Description of Business	'
	Note 1 -  Description of Business
	Organization
	Ener-Core, Inc. (the “Company”, “we”, “us”, “our”), a Nevada corporation, was formed on April 29, 2010 as Inventtech, Inc.  On July 1, 2013, we acquired our wholly owned subsidiary, Ener-Core Power, Inc., (formerly Flex Power Generation, Inc.), a Delaware corporation.  The shareholders of Ener-Core Power, Inc. are now our majority shareholders and the management of Ener-Core Power, Inc. is now our management.  Therefore the acquisition is treated as a “reverse merger” and our financial statements are those of Ener-Core Power, Inc.  All equity amounts presented have been retroactively restated to reflect the reverse merger as if it had occurred November 12, 2012.
	Reverse Merger
	We entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Ener-Core Power, Inc. (“Ener-Core Power”), a Delaware corporation, and Flex Merger Acquisition Sub, Inc., a Delaware corporation and our wholly owned subsidiary (“Merger Sub”), pursuant to which the Merger Sub would merge with and into Ener-Core Power, with Ener-Core Power as the surviving entity (the “Merger”). Prior to the merger, we were a public reporting “shell company,” as defined in Rule 12b-2 of the Securities Exchange Act of 1934, as amended.  The Merger Agreement was approved by the boards of directors of each of the parties to the Merger Agreement.  In April 2013, the pre-merger public shell company effected a 30-for-1 forward split of its common stock.  All share amounts have been retroactively restated to reflect the effect of the stock split.
	As provided in the Contribution Agreement dated November 12, 2012 (the “Contribution Agreement”) by and among FlexEnergy, Inc. (“FlexEnergy”, “Parent”,), FlexEnergy Energy Systems, Inc. (“FEES”), and Ener-Core Power, Inc. (“Successor”), Ener-Core Power, Inc. was spun-off from FlexEnergy, Inc. as a separate corporation.  As a part of that transaction, Ener-Core Power, Inc. received all assets (including intellectual property) and certain liabilities pertaining to the Gradual Oxidizer business (Predecessor), the business carved out of Parent.  The owners of Predecessor did not distribute ownership of Successor entity pro rata.  The assets and liabilities were transferred to us and recorded at their historical carrying amounts since the transaction was a transfer of net assets between entities under common control.
	On July 1, 2013, Ener-Core Power completed the Merger with us.  Upon completion of the merger, the operating company immediately became a public company.  The Merger was accounted for as a “reverse merger” and recapitalization. As part of the reverse merger, the pre-merger public shell company shareholders cancelled 120,520,000 of common stock which were then outstanding.  This cancellation has been retroactively accounted for as of the inception of Ener-Core Power, Inc. on November 12, 2012. Accordingly, Ener-Core Power was deemed to be the accounting acquirer in the transaction and, consequently, the transaction was treated as a recapitalization of Ener-Core Power.  Accordingly, the assets and liabilities and the historical operations that are reflected in the financial statements are those of Ener-Core Power and are recorded at the historical cost basis of Ener-Core Power.  Our assets, liabilities and results of operations were de minimis at the time of merger.
	Description of the Business
	We design, develop, and manufacture products based on proprietary technologies that aim to expand the operating range of gaseous fuel while improving emissions, which technologies we refer to collectively as “Gradual Oxidization” or “Gradual Oxidizer.”  Our products aim to expand power generation into previously uneconomical markets while, at the same time, reduce gaseous emissions from industrial processes that contribute to air pollution and climate change.  The Gradual Oxidizer integrates with a gas turbine and generator to create a power station.
	Our product, the FP250, is a complete system consisting of our designed and patented gradual oxidizer, integrated with a gas turbine and generator.  The FP250 has been designed to operate on fuels from 100% combustible gas down to concentrations of 5% or less combustible gas content.  The FP250 has applications in landfill, oil production, coal mining, and other operations, and offers our customers two distinct value propositions: the destruction of low quality waste gases with no harmful emissions and the generation of energy from a renewable fuel source.
	We are currently developing our second commercial product, the Ener-Core Powerstation KG2-3G/GO (“KG2”), which will combine our Gradual Oxidizer with a two megawatt gas turbine developed by Dresser-Rand a.s., a subsidiary of Dresser-Rand Group Inc. (“Dresser Rand”).  We have completed system layout and analytic models integrating our Gradual Oxidizer with the turbine and have initiated design and development of the KG2.  We expect to field test units in late 2014 or 2015, with initial commercial shipments shortly thereafter.
	We sell our products directly and through distributors in two countries, the United States and Netherlands.
	Going Concern
	Our condensed consolidated financial statements are prepared using the accrual method of accounting in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and have been prepared on a going concern basis, which contemplates the realization of assets and settlement of liabilities in the normal course of business.  Since our inception, we have made a substantial investment in research and development to develop the Gradual Oxidizer, have successfully deployed a FP250 field test unit at the U.S. Army base at Fort Benning, Georgia, and shipped our first commercial product in November 2013.
	We have not achieved profitable operations or positive cash flows since inception and have not yet established an ongoing source of revenues sufficient to cover our operating costs and allow us to continue as a going concern.As of May 9, 2014, we have a substantial working capital deficit and require significant additional capital to continue operations.  We must secure additional funding to pay our current liabilities, continue as a going concern and execute our business plan.
	Management’s plan is to obtain such resources by obtaining capital sufficient to meet our operating expenses by seeking additional equity and/or debt financing. The cash and cash equivalents balance (including restricted cash) on March 31, 2014 and May 9, 2014 was $0.2 million and $3.4 million (including restricted cash of $2.3 million), respectively. On April 16, 2014, we closed $4.6 million of senior secured financing (Note 13), whereby the lender made available gross proceeds of $4.0 million, of which $2.3 million is constrained in a Control Account subject to be released at the lender’s option when we are not in default and there is no Equity Control Failure and to the extent such funds exceed the aggregate principal amount then outstanding.  We project that our unrestricted cash balance of $1.1 million as of May 9, 2014, will continue to meet our working capital needs, general corporate purposes, and related obligations into the third quarter of 2014.  To the extent that the lender, at its sole option, releases funds from the Control Account, we will be able to meet our operating needs and obligations further into 2014.
	We will pursue raising additional debt or equity financing to fund our operations and product development.  If future funds are raised through issuance of stock or debt, these securities could have rights, privileges, or preferences senior to those of common stock and debt covenants that could impose restrictions on the Company’s operations. The sale of additional equity securities or debt financing will likely result in additional dilution to the Company’s current shareholders.  We cannot make any assurances that any additional financing will be completed on a timely basis, on acceptable terms or at all.   Management’s inability to successfully complete any other financing will adversely impact our ability to continue as a going concern. Even if we are able to secure financing, we may still have to significantly reduce costs and delay projects, which would adversely affect our business, customers and program development.  If our business fails or we are unable to seek immediate financing, our investors may face a complete loss of their investment.
	The accompanying unaudited condensed consolidated financial statements do not give effect to any adjustments that might be necessary if we were unable to meet our obligations or continue operations.

Summary of Significant Accounting Policies	'
	Note 2 -  Summary of Significant Accounting Policies
	Basis of Presentation
	The Company has prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim reporting. We have condensed or omitted certain information and footnote disclosures normally included in our annual financial statements prepared in accordance with GAAP pursuant to such rules and regulations. The unaudited condensed financial statements reflect all adjustments, which are normal and recurring, that are, in the opinion of management, necessary to fairly state the financial position as of March 31, 2014 and the results of operations and cash flows for the related three months ended March 31, 2014 and 2013. The results of operations for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 or for any future periods. The unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2013, that have been included in the Company's Form 10-K filed on April 15, 2014.
	The accompanying consolidated financial statements include our accounts and our wholly-owned subsidiary, Ener-Core Power, Inc.  All significant intercompany transactions and accounts have been eliminated in consolidation. All amounts are rounded to the nearest $000, except certain per share amounts within the footnotes.
	The accompanying financial statements have been prepared in accordance with GAAP.
	Segments
	We operate in one segment.  All of our operations are located domestically.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period.  Significant items subject to such estimates and assumptions include the valuation of certain assets, useful lives, and carrying amounts of property and equipment, equity instruments and share-based compensation; provision for contract losses; valuation allowances for deferred income tax assets; and exposure to warranty and other contingent liabilities.  We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.  Actual results may differ from these estimates.
	Foreign Currency Adjustments
	Our functional currency for all operations worldwide is the U.S. dollar.  Nonmonetary assets and liabilities are translated at historical rates and monetary assets and liabilities are translated at exchange rates in effect at the end of the year. Income statement accounts are translated at average rates for the year.  At March 31, 2014 and December 31, 2013, we did not hold any foreign currency asset or liability amounts.  Gains and losses resulting from foreign currency transactions are reported as other income in the period they occurred.
	Concentrations of Credit Risk
	Cash and Cash Equivalents
	We maintain our non-interest bearing transactional cash accounts at financial institutions for which the Federal Deposit Insurance Corporation (“FDIC”) provides insurance coverage of up to $250,000.  For interest bearing cash accounts, from time to time, balances exceed the amount insured by the FDIC.  We have not experienced any losses in such accounts and believe we are not exposed to any significant credit risk related to these deposits.  At March 31, 2014, we did not have amounts in excess of the FDIC limit.
	We consider all highly liquid investments available for current use with an initial maturity of three months or less and are not restricted to be cash equivalents.  We invest our cash in short-term money market accounts.
	Restricted Cash
	Under a credit card processing agreement with a financial institution that was entered in 2013, we are required to maintain funds on deposit with the financial institution as collateral.  The amount of the deposit is at the discretion of the financial institution was $50,000 on March 31, 2014 and December 31, 2013.
	Accounts Receivable
	Our accounts receivable are typically from credit worthy customers or, for international customers are supported by guarantees or letters of credit.  For those customers to whom we extend credit, we perform periodic evaluations of our customers and maintain allowances for potential credit losses as deemed necessary.  We generally do not require collateral to secure accounts receivable.  We have a policy of reserving for uncollectible accounts based on our best estimate of the amount of probable credit losses in existing accounts receivable.  We periodically review our accounts receivable to determine whether an allowance is necessary based on an analysis of past due accounts and other factors that may indicate that the realization of an account may be in doubt.  Account balances deemed to be uncollectible are charged to the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.
	At March 31, 2014 and December 31, 2013, we did not have any allowance for doubtful accounts.  Although we expect to collect amounts due, actual collections may differ from the recorded amounts.
	As of March 31, 2014 and December 31, 2013, one customer accounted for 100% of total accounts receivable. There were no revenues for the three months ended March 31, 2014.  One customer accounted for 100% of net revenues for the three months ended March 31, 2013.
	Accounts Payable
	As of March 31, 2014 and December 31, 2013, four and two vendors accounted for approximately 57% and 48% of total accounts payable, respectively.
	Inventory
	Inventory, which consists of raw materials, is stated at the lower of cost or net realizable value, with cost being determined by the average-cost method, which approximates the first-in, first-out method.  At each balance sheet date, we evaluate our ending inventory for excess quantities and obsolescence.  This evaluation primarily includes an analysis of forecasted demand in relation to the inventory on hand, among consideration of other factors.  Based upon the evaluation, provisions are made to reduce excess or obsolete inventories to their estimated net realizable values.  Once established, write-downs are considered permanent adjustments to the cost basis of the respective inventories.  At March 31, 2014 and December 31, 2013, we did not have a reserve for slow-moving or obsolete inventory.
	Costs in Excess of Billings on Uncompleted Contracts
	Costs in excess of billings on uncompleted contracts in the accompanying consolidated balance sheets represents accumulation of costs for labor, materials, overhead and other costs that have been incurred. These costs will be recognized as costs of goods sold when the contract is considered complete in accordance with the completed-contract method.
	Property and Equipment
	Property and equipment are stated at cost, and are being depreciated using the straight-line method over the estimated useful lives of the related assets, ranging from three to ten years. Maintenance and repairs that do not improve or extend the lives of the respective assets are expensed.  At the time property and equipment are retired or otherwise disposed of, the cost and related accumulated depreciation accounts are relieved of the applicable amounts.  Gains or losses from retirements or sales are reflected in the consolidated statements of operations.
	Deposits
	Deposits primarily consist of amounts incurred or paid in advance of the receipt of fixed assets or are deposits for rent and insurance.
	Deferred Rent
	We record deferred rent expense, which represents the temporary differences between the reporting of rental expense on the financial statements and the actual amounts remitted to the landlord. The deferred rent portion of lease agreements are leasing inducements provided by the landlord. Also, tenant improvement allowances provided are recorded as a deferred rent liability and recognized ratably as a reduction to rent expense over the lease term.
	Intangible Assets
	We amortize our intangible assets with finite lives over their estimated useful lives.  See Note 6 for additional details regarding the components and estimated useful lives of intangible assets.
	Impairment of Long-Lived Assets
	We account for our long-lived assets in accordance with the accounting standards which require that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the historical carrying value of an asset may no longer be appropriate.  We consider the carrying value of assets may not be recoverable based upon its review of the following events or changes in circumstances: the asset’s ability to continue to generate income from operations and positive cash flow in future periods; loss of legal ownership or title to the assets; significant changes in our strategic business objectives and utilization of the asset; or significant negative industry or economic trends.  An impairment loss would be recognized when estimated future cash flows expected to result from the use of the asset are less than its carrying amount. As of March 31, 2014 and December 31, 2013, we do not believe there have been any other impairments of our long-lived assets.  There can be no assurance, however, that market conditions will not change or demand for our products will continue, which could result in impairment of long-lived assets in the future.
	Fair Value of Financial Instruments
	Our financial instruments consist primarily of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, and capital lease liabilities.  The carrying amounts of the financial instruments are reasonable estimates of their fair values due to their short-term nature or proximity to market rates for similar debt.
	We determine the fair value of our financial instruments based on a three-level hierarchy established for fair value measurements under which these assets and liabilities must be grouped, based on significant levels of observable or unobservable inputs.  Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect management’s market assumptions.  This hierarchy requires the use of observable market data when available.  These two types of inputs have created the following fair-value hierarchy:
		·	Level 1: Valuations based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Currently, we do not have any items classified as Level 1.
		·	Level 2: Valuations based on observable inputs (other than Level 1 prices), such as quoted prices for similar assets at the measurement date quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability.   Funds maintained in our money market account are classified as Level 2.
		·	Level 3: Valuations based on inputs that require inputs that are both significant to the fair value measurement and unobservable and involve management judgment (i.e., supported by little or no market activity). Currently, we do not have any items classified as Level 3.
	If the inputs used to measure fair value fall in different levels of the fair value hierarchy, a financial security’s hierarchy level is based upon the lowest level of input that is significant to the fair value measurement.
	Revenue Recognition
	We generate revenue from the sale of our clean power energy systems and from consulting services. Revenue is recognized when there is persuasive evidence of an arrangement, product delivery and acceptance have occurred, the sales price is fixed or determinable and collectability of the resulting receivable is reasonable assured.  Amounts billed to clients for shipping and handling are classified as sales of product with related costs incurred included in cost of sales.
	Provisions for discounts and rebates to customers, estimated returns and allowances, and other adjustments are provided for in the same period the related revenue is recorded.  We defer any revenue for which the services have not been performed or is subject to refund until such time that we and our customer jointly determine that the services have been performed or no refund will be required.
	Revenues under long-term construction contracts are generally recognized using the completed-contract method of accounting.  Long-term construction-type contracts for which reasonably dependable estimates cannot be made or for which inherent hazards make estimates difficult are accounted for under the completed-contract method. Revenues under the completed-contract method are recognized upon substantial completion – that is acceptance by the customer, compliance with performance specifications demonstrated in a factory acceptance test or similar event.  Accordingly, during the period of contract performance, billings and costs are accumulated on the balance sheet, but no profit or income is recorded before completion or substantial completion of the work.  Anticipated losses on contracts are recognized in full in the period in which losses become probable and estimable.  Changes in estimate of profit or loss on contracts are included in earnings on a cumulative basis in the period the estimate is changed.  We have  deferred all amounts received on our contract with Efficient Energy Conversion Turbo Machinery, B.V. (“EECT”) until the contract is substantially complete, at which time all advanced payments received on the contract ($701,000), will be recorded as revenue.  As of March 31, 2014 and December 31, 2013, we had a provision for contract loss of approximately $75,000 and $100,000, respectively, related to our contract with EECT.
	Research and Development Costs
	Research and development costs are expensed as incurred.  Research and development was $792,000 and $276,000 for the three months ended March 31, 2014 and 2013, respectively.
	Share-Based Compensation
	We maintain a stock option plan (see Note 10) and record expenses attributable to the stock option plan. We amortize share-based compensation from the date of grant on a weighted average basis over the requisite service (vesting) period for the entire award.
	We account for equity instruments issued to consultants and vendors in exchange for goods and services at fair value.  The measurement date for the fair value of the equity instruments issued is determined at the earlier of (i) the date at which a commitment for performance by the consultant or vendor is reached or (ii) the date at which the consultant’s or vendor’s performance is complete.  In the case of equity instruments issued to consultants, the fair value of the equity instrument is recognized over the term of the consulting agreement.
	In accordance with the accounting standards, an asset acquired in exchange for the issuance of fully vested, non-forfeitable equity instruments should not be presented or classified as an offset to equity on the grantor’s balance sheet once the equity instrument is granted for accounting purposes.  Accordingly, we record the fair value of the fully vested, non-forfeitable common stock issued for future consulting services as prepaid expense in our consolidated balance sheets.
	Income Taxes
	We account for income taxes under FASB ASC 740 “Income Taxes.” Under the asset and liability method of FASB ASC 740, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under FASB ASC 740, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period the enactment occurs. A valuation allowance is provided for certain deferred tax assets if it is more likely than not that we will not realize tax assets through future operations.
	Earnings (Loss) per Share
	Basic loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares assumed to be outstanding during the period of computation.  Diluted loss per share is computed similar to basic loss per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential shares had been issued and if the additional common shares were dilutive.  Options and warrants to purchase approximately 9.3 million shares of common stock were outstanding at March 31, 2014.  There were no options or warrants outstanding at March 31, 2013. Dilutive equivalents were excluded from the computation of diluted loss per share due to the anti-dilutive effect on net loss per share.

Effective January 1, 2014, we adopted FASB ASU 2013-07, Presentation of Financial Statements (Topic 205): Liquidation Basis of Accounting (“ASU 2013-07”). The amendments in ASU 2013-07 clarify when an entity should apply the liquidation basis of accounting and provide principles for the recognition and measurement of associated assets and liabilities. In accordance with the amendments, the liquidation basis is used when liquidation is imminent.  Liquidation is considered imminent when the likelihood is remote that the organization will return from liquidation and either: (a) a plan for liquidation is approved by the person or persons with the authority to make such a plan effective and the likelihood is remote that the execution of the plan will be blocked by other parties; or (b) a plan for liquidation is being imposed by other forces. The adoption of ASU 2013-07 did not have a material impact on our condensed consolidated financial statements.
Effective January 1, 2014, we adopted FASB ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). The amendments in ASU 2013-11 clarify that an unrecognized tax benefit, or a portion of  an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed.  In situations where a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The adoption of ASU 2013-11 did not have a material impact on our condensed consolidated financial statements.

	Note 10 -  Stock Options and Warrants
	On July 1, 2013, our Board of Directors adopted and approved the 2013 Equity Incentive Plan.  The plan authorizes us to grant non-qualified stock options and restricted stock purchase rights to purchase up to 14,000,000 shares of our common stock with vesting to employees (including officers) and other service providers.  At March 31, 2014, 5.3 million shares were available for future grants and total unrecognized deferred stock compensation expected to be recognized over the remaining weighted-average vesting periods of 2.5 years for outstanding grants was $5.2 million.
	The fair value of option awards is estimated on the grant date using the Black-Scholes option valuation model.
	Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive equity awards, and subsequent events are not indicative of the reasonableness of the original estimates of fair value made by us.  The following table presents the weighted-average grant date assumptions used to estimate the fair value of options and stock appreciation rights granted.
		March 31,		December 31,
		2014		2013
		(unaudited)
	Expected volatility	N/A			73.50%
	Dividend yield	N/A			0.00%
	Risk-free interest rate	N/A			1.26%
	Expected life (in years)	N/A			6.64
	Expected volatility represents the estimated volatility of the shares over the expected life of the options.  We have estimated the expected volatility based on the weighted-average historical volatilities of a pool of public companies that are comparable to Ener-Core.
	We use an expected dividend yield of zero since no dividends are expected to be paid.  The risk-free interest rate for periods within the expected life of the option is derived from the U.S. treasury interest rates in effect at the date of grant.  The expected option life represents the period of time the option is expected to be outstanding.  The simplified method is used to estimate the term since we do not have sufficient exercise history to calculate the expected life of the options.
	Stock-based compensation expense is recorded only for those awards expected to vest.  Currently, the forfeiture rate is zero.  The rate is adjusted if actual forfeitures differ from the estimates in order to recognize compensation cost only for those awards that actually vest.  If factors change and different assumptions are employed in future periods, the share-based compensation expense may differ from that recognized in previous periods.
	Stock-based award activity was as follows:

	Exercisable on March 31, 2014			2,587,000		$	1.227		5.84	$	-
	The options granted have a contract term ranging between five and seven years.  Options granted prior to November 2013 vest over a 2.8 to 3 year period, with 33% of the options vesting three to six months after grant and the remainder ratably over the vesting term.  Options granted after November 2013 vest over a four year period, with 25% vesting after one year and the remainder ratably over the remaining three years.

	During the first quarter of 2013, stock options were exercised prior to vesting and all unvested options are subject to repurchase rights.  Under the terms of the stock option plan, we repurchased 92,323 shares from an employee for $92 during the three months ended March 31, 2014.  These shares have been returned to the pool of shares eligible to be issued under the stock option plan.

	In March 2013, we borrowed $260,000 from a stockholder under a note payable that was due March 28, 2014, or earlier, upon completion of the merger.  The note accrued interest at the rate of 12% and was convertible at the lender’s option into common stock at $0.75 per share.  The note was subsequently converted in April 2013 as described in Note 10.  As the note was outstanding less than one month, no interest was due to the lender.
	In March 2013, a stockholder advanced us a total of $411,000 for operating capital.  The advance did not bear interest and was due on demand.  In April 2013, the advances were converted into our common stock at $0.75 per share at the stockholders’ election, as described in Note 10.
	In June 2013, we borrowed $100,000 from each of three individual stockholders under notes payable that were due December 31, 2013, or earlier, upon completion of the merger.  The notes accrued interest at the rate of 8% and are convertible at the lender’s option into common stock at $0.75 per share. On July 1, 2013, $100,000 was converted into shares of common stock in the merger-related private placement and $200,025, which included $25 of accrued interest, was repaid at the closing of the Merger.

	EECT Agreement
	On December 31, 2012, we entered into a Master Purchase and Resale Agreement (“MPRSA”) with EECT. As part of this agreement, EECT is committed to buy a certain number of the FP250 and related optional equipment in order to maintain exclusivity in the region.  The pricing for the first unit was $760,000 and subsequent units will be sold at a higher price than the first unit.  In accordance with the MPRSA, EECT placed a Purchase Order (“PO”) with us on December 31, 2012, for the purchase on the first unit at $760,000.  The order was conditional on the issuance of an irrevocable letter of credit to us, according to the terms of the PO.  Such irrevocable letter of credit was issued on March 1, 2013, in the amount of 533,000 Euros, and we have acknowledged the acceptance of the PO on the same date.  On November 14, 2013, we shipped the FP250 and on December 24, 2013, we received the proceeds from the letter of credit.
	Lease
	We lease our office facility, research and development facility and equipment under operating leases, which for the most part, are renewable.   The leases also provide that we pay insurance and taxes.
	Future minimum rental payments under operating leases that have initial noncancelable lease terms in excess of one year as of March 31, 2014 are as follows:

	2016		329,000
	2017		3,000
	2018		2,000
		$	933,000
	Minimum rent payments under operating leases are recognized on a straight-line basis over the term of the Lease.  Rent expense, net of sublease income, was $70,000 and $35,000 for the three months ended March 31, 2014 and 2013, respectively.
	Our current headquarters is located at 9400 Toledo Way, Irvine, California 92618.  The property consists of a mixed use commercial office, production, and warehouse facility of 32,649 square feet.  Effective August 1, 2013, we assumed this lease (the “Lease”).  The Lease has a remaining term of 39 months and expires December 31, 2016.  The monthly expense rent is $25,285 and increases on an annual basis.
	In addition, we lease space from the Regents of the University of California, Irvine, for the installation and demonstration of the FP250 equipment. The lease expires on April 1, 2015 and the monthly payment is $7,780. The university will provide certain goods and services including certain research and development services.
	Sublease – 9400 Toledo
	In September 2013, we began subleasing a certain portion of this property to a third party on a month-to-month basis at a rate of $720 per month.
	We also finalized a Sublease Agreement with FEES, effective August 1, 2013 through October 1, 2013, (the “Sublease”), whereby FEES is temporarily subleasing 6,000 square feet of the property for warehousing, storage and/or office purposes for a monthly rent of $3,300.  Under the Sublease, FEES assigned to us its initial security deposit under the Lease of $27,630.
	On March 7, 2014, we subleased 5,000 square feet of office space at our headquarters, commencing March 1, 2014 to a third party tenant.  The lease is for 34 months and requires payments of $7,000 per month for twelve months increasing to $7,210 for the next twelve months and $7,426.30 for the remaining ten months.  The lease includes use of the existing furniture and telephone equipment over the life of the lease.

	On April 16, 2014, we closed a securities purchase agreement (“April 2014 SPA”), with five institutional and accredited investors.  Pursuant to the terms of the April 2014 SPA, we issued and sold to these investors our senior secured convertible notes in the aggregate original principal amount of $4,575,000 (“Notes”), and warrants to purchase up to 4,097,015 shares of our common stock (“Warrants”), on the terms set forth below (“April 2014 Private Placement”).
	The Notes mature 18 months from their issuance and were purchased for $4,003,125 in the aggregate with an original issue discount of $571,875.  The Notes bear an effective annual interest rate of 8.61%, which increases to 15% if there is an event of default (as defined in the Notes).  The initial conversion price of the Notes is $0.67 per share (“Conversion Price”).  Beginning on July 1, 2014, we will pay to the Note holder an amount equal to (i) one-sixteenth (1/16th) of the original principal amount of the Note (or the principal outstanding on such date, if less) plus (ii) the accrued and unpaid interest with respect to such principal plus (iii) the accrued and unpaid late charge (if any) with respect to such principal and interest (each, an “Installment Amount”). The Holder has the ability to defer such monthly payments in its sole discretion.  Up to four times prior to maturity of the Notes, each holder may accelerate payment of the sum of the following: (a) the Installment Amount, (b) any Installment Amount which payment such Note holder previously deferred, and (c) any accrued and unpaid interest and late charges, if any; provided, however, that any such accelerated amount shall not be greater than two times the amount set forth in clause (a) above. Each monthly payment may be made in cash, in shares of our common stock, or in a combination of cash and shares of its common stock. Our ability to make such payments with shares of our common stock will be subject to the satisfaction of certain equity conditions.  Subject to the satisfaction of certain equity conditions, we may redeem all, but not less than all, of the Notes then outstanding at any time at 115% of the Conversion Amount being redeemed
	The Warrants issued to the investors are immediately exercisable, have an initial exercise price of $0.78 per share (“Exercise Price”) and expire on the 60-month anniversary of their initial issuance.  If we sell or issue shares of Common Stock at less than the then applicable exercise price (subject to certain exceptions), then the exercise price shall be reduced to the price of such dilutive issuance.
	In connection with the sale of the Notes and the Warrants, we entered into a registration rights agreement (“April 2014 RRA”) to register 135% of the shares issuable under the Notes and the Warrants.  In addition, we entered into a pledge and security agreement (“Security Agreement”) granting security interest of all of our personal property to the collateral agent for the investors (“Collateral Agent”), as well as a special deposit account control agreement (“Control Agreement”) granting the Collateral Agent control of the control account established to hold a portion of the proceeds from the investors (the “Control Account”).
	We received gross proceeds of $4.0 million, less transaction expenses of approximately $250,000, of which $2.3 million placed in a control account pursuant the Control Agreement and is restricted to our usage.
	Stock Option Re-Pricing
	On April 28, 2014, our board of directors approved the re-pricing and vesting schedules of outstanding stock options of 8,630,000 shares of our common stock previously granted to officers, directors, employees and consultants pursuant to the 2013 Equity Incentive Award Plan.  The options were re-priced at $0.35, the closing price of our stock on April 28, 2014.
	The Outstanding Options had been issued with exercise prices ranging from $1.00 to $1.54 per share.  The vesting schedule for the Outstanding Options also varied.
	The re-pricing and vesting schedule changes are being effected by cancelling the Outstanding Options and concurrently entering into new Stock Option Agreements with the Optionees (the “New Options”) to reflect the new exercise price and vesting schedule.   The New Options will all have the following vesting schedule, 15% of the total number of shares granted shall vest immediately upon signing the new Stock Option Agreements, and 1/36 of the remainder number of shares shall vest each full month thereafter.

Summary of Significant Accounting Policies (Policies)	3 Months Ended

Summary of Significant Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	The Company has prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim reporting. We have condensed or omitted certain information and footnote disclosures normally included in our annual financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) pursuant to such rules and regulations. The unaudited condensed financial statements reflect all adjustments, which are normal and recurring, that are, in the opinion of management, necessary to fairly state the financial position as of March 31, 2014 and the results of operations and cash flows for the related three months ended March 31, 2014 and 2013. The results of operations for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 or for any future periods. The unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2013, that have been included in the Company's Form 10-K filed on April 15, 2014.
	The accompanying consolidated financial statements include our accounts and our wholly-owned subsidiary, Ener-Core Power, Inc.  All significant intercompany transactions and accounts have been eliminated in consolidation. All amounts are rounded to the nearest $000, except certain per share amounts within the footnotes.
	The accompanying financial statements have been prepared in accordance with GAAP.
Segments	'
	Segments
	We operate in one segment.  All of our operations are located domestically.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period.  Significant items subject to such estimates and assumptions include the valuation of certain assets, useful lives, and carrying amounts of property and equipment, equity instruments and share-based compensation; provision for contract losses; valuation allowances for deferred income tax assets; and exposure to warranty and other contingent liabilities.  We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.  Actual results may differ from these estimates.
Foreign Currency Adjustments	'
	Foreign Currency Adjustments
	Our functional currency for all operations worldwide is the U.S. dollar.  Nonmonetary assets and liabilities are translated at historical rates and monetary assets and liabilities are translated at exchange rates in effect at the end of the year. Income statement accounts are translated at average rates for the year.  At March 31, 2014 and December 31, 2013, we did not hold any foreign currency asset or liability amounts.  Gains and losses resulting from foreign currency transactions are reported as other income in the period they occurred.
Concentrations of Credit Risk	'
	Concentrations of Credit Risk
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	We maintain our non-interest bearing transactional cash accounts at financial institutions for which the Federal Deposit Insurance Corporation (“FDIC”) provides insurance coverage of up to $250,000.  For interest bearing cash accounts, from time to time, balances exceed the amount insured by the FDIC.  We have not experienced any losses in such accounts and believe we are not exposed to any significant credit risk related to these deposits.  At March 31, 2014, we did not have amounts in excess of the FDIC limit.
	We consider all highly liquid investments available for current use with an initial maturity of three months or less and are not restricted to be cash equivalents.  We invest our cash in short-term money market accounts.
Restricted Cash	'
	Restricted Cash
	Under a credit card processing agreement with a financial institution that was entered in 2013, we are required to maintain funds on deposit with the financial institution as collateral.  The amount of the deposit is at the discretion of the financial institution was $50,000 on March 31, 2014 and December 31, 2013.
Accounts Receivable	'
	Accounts Receivable
	Our accounts receivable are typically from credit worthy customers or, for international customers are supported by guarantees or letters of credit.  For those customers to whom we extend credit, we perform periodic evaluations of our customers and maintain allowances for potential credit losses as deemed necessary.  We generally do not require collateral to secure accounts receivable.  We have a policy of reserving for uncollectible accounts based on our best estimate of the amount of probable credit losses in existing accounts receivable.  We periodically review our accounts receivable to determine whether an allowance is necessary based on an analysis of past due accounts and other factors that may indicate that the realization of an account may be in doubt.  Account balances deemed to be uncollectible are charged to the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.
	At March 31, 2014 and December 31, 2013, we did not have any allowance for doubtful accounts.  Although we expect to collect amounts due, actual collections may differ from the recorded amounts.
	As of March 31, 2014 and December 31, 2013, one customer, accounted for 100% of total accounts receivable. There were no revenues for the three months ended March 31, 2014.  One customer accounted for 100% of net revenues for the three months ended March 31, 2013.
Accounts Payable	'
	Accounts Payable
	As of March 31, 2014 and December 31, 2013, four and two vendors accounted for approximately 57% and 48% of total accounts payable, respectively.
Inventory	'
	Inventory
	Inventory, which consists of raw materials, is stated at the lower of cost or net realizable value, with cost being determined by the average-cost method, which approximates the first-in, first-out method.  At each balance sheet date, we evaluate our ending inventory for excess quantities and obsolescence.  This evaluation primarily includes an analysis of forecasted demand in relation to the inventory on hand, among consideration of other factors.  Based upon the evaluation, provisions are made to reduce excess or obsolete inventories to their estimated net realizable values.  Once established, write-downs are considered permanent adjustments to the cost basis of the respective inventories.  At March 31, 2014 and December 31, 2013, we did not have a reserve for slow-moving or obsolete inventory.
Costs in Excess of Billings on Uncompleted Contracts	'
	Costs in Excess of Billings on Uncompleted Contracts
	Costs in excess of billings on uncompleted contracts in the accompanying consolidated balance sheets represents accumulation of costs for labor, materials, overhead and other costs that have been incurred. These costs will be recognized as costs of goods sold when the contract is considered complete in accordance with the completed-contract method.
Property and Equipment	'
	Property and Equipment
	Property and equipment are stated at cost, and are being depreciated using the straight-line method over the estimated useful lives of the related assets, ranging from three to ten years. Maintenance and repairs that do not improve or extend the lives of the respective assets are expensed.  At the time property and equipment are retired or otherwise disposed of, the cost and related accumulated depreciation accounts are relieved of the applicable amounts.  Gains or losses from retirements or sales are reflected in the consolidated statements of operations.
Deposits	'
	Deposits
	Deposits primarily consist of amounts incurred or paid in advance of the receipt of fixed assets or are deposits for rent and insurance.
Deferred Rent	'
	Deferred Rent
	We record deferred rent expense, which represents the temporary differences between the reporting of rental expense on the financial statements and the actual amounts remitted to the landlord. The deferred rent portion of lease agreements are leasing inducements provided by the landlord. Also, tenant improvement allowances provided are recorded as a deferred rent liability and recognized ratably as a reduction to rent expense over the lease term.
Intangible Assets	'
	Intangible Assets
	We amortize our intangible assets with finite lives over their estimated useful lives.  See Note 6 for additional details regarding the components and estimated useful lives of intangible assets.
Impairment of Long-Lived Assets	'
	Impairment of Long-Lived Assets
	We account for our long-lived assets in accordance with the accounting standards which require that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the historical carrying value of an asset may no longer be appropriate.  We consider the carrying value of assets may not be recoverable based upon its review of the following events or changes in circumstances: the asset’s ability to continue to generate income from operations and positive cash flow in future periods; loss of legal ownership or title to the assets; significant changes in our strategic business objectives and utilization of the asset; or significant negative industry or economic trends.  An impairment loss would be recognized when estimated future cash flows expected to result from the use of the asset are less than its carrying amount. As of March 31, 2014 and December 31, 2013, we do not believe there have been any other impairments of our long-lived assets.  There can be no assurance, however, that market conditions will not change or demand for our products will continue, which could result in impairment of long-lived assets in the future.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	Our financial instruments consist primarily of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, and capital lease liabilities.  The carrying amounts of the financial instruments are reasonable estimates of their fair values due to their short-term nature or proximity to market rates for similar debt.
	We determine the fair value of our financial instruments based on a three-level hierarchy established for fair value measurements under which these assets and liabilities must be grouped, based on significant levels of observable or unobservable inputs.  Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect management’s market assumptions.  This hierarchy requires the use of observable market data when available.  These two types of inputs have created the following fair-value hierarchy:
		·	Level 1: Valuations based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Currently, we do not have any items classified as Level 1.
		·	Level 2: Valuations based on observable inputs (other than Level 1 prices), such as quoted prices for similar assets at the measurement date quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability.   Funds maintained in our money market account are classified as Level 2.
		·	Level 3: Valuations based on inputs that require inputs that are both significant to the fair value measurement and unobservable and involve management judgment (i.e., supported by little or no market activity). Currently, we do not have any items classified as Level 3.
	If the inputs used to measure fair value fall in different levels of the fair value hierarchy, a financial security’s hierarchy level is based upon the lowest level of input that is significant to the fair value measurement.
Revenue Recognition	'
	Revenue Recognition
	We generate revenue from the sale of our clean power energy systems and from consulting services. Revenue is recognized when there is persuasive evidence of an arrangement, product delivery and acceptance have occurred, the sales price is fixed or determinable and collectability of the resulting receivable is reasonable assured.  Amounts billed to clients for shipping and handling are classified as sales of product with related costs incurred included in cost of sales.
	Provisions for discounts and rebates to customers, estimated returns and allowances, and other adjustments are provided for in the same period the related revenue is recorded.  We defer any revenue for which the services have not been performed or is subject to refund until such time that we and our customer jointly determine that the services have been performed or no refund will be required.
	Revenues under long-term construction contracts are generally recognized using the completed-contract method of accounting.  Long-term construction-type contracts for which reasonably dependable estimates cannot be made or for which inherent hazards make estimates difficult are accounted for under the completed-contract method. Revenues under the completed-contract method are recognized upon substantial completion – that is acceptance by the customer, compliance with performance specifications demonstrated in a factory acceptance test or similar event.  Accordingly, during the period of contract performance, billings and costs are accumulated on the balance sheet, but no profit or income is recorded before completion or substantial completion of the work.  Anticipated losses on contracts are recognized in full in the period in which losses become probable and estimable.  Changes in estimate of profit or loss on contracts are included in earnings on a cumulative basis in the period the estimate is changed.  We have  deferred all amounts received on our contract with Efficient Energy Conversion Turbo Machinery, B.V. (“EECT”) until the contract is substantially complete, at which time all advanced payments received on the contract ($701,000), will be recorded as revenue.  As of March 31, 2014 and December 31, 2013, we had a provision for contract loss of approximately $75,000 and $100,000, respectively, related to our contract with EECT.
Research and Development Costs	'
	Research and Development Costs
	Research and development costs are expensed as incurred.  Research and development was $792,000 and $276,000 for the three months ended March 31, 2014 and 2013, respectively.
Share-Based Compensation	'
	Share-Based Compensation
	We maintain a stock option plan (see Note 10) and record expenses attributable to the stock option plan. We amortize share-based compensation from the date of grant on a weighted average basis over the requisite service (vesting) period for the entire award.
	We account for equity instruments issued to consultants and vendors in exchange for goods and services at fair value.  The measurement date for the fair value of the equity instruments issued is determined at the earlier of (i) the date at which a commitment for performance by the consultant or vendor is reached or (ii) the date at which the consultant’s or vendor’s performance is complete.  In the case of equity instruments issued to consultants, the fair value of the equity instrument is recognized over the term of the consulting agreement.
	In accordance with the accounting standards, an asset acquired in exchange for the issuance of fully vested, non-forfeitable equity instruments should not be presented or classified as an offset to equity on the grantor’s balance sheet once the equity instrument is granted for accounting purposes.  Accordingly, we record the fair value of the fully vested, non-forfeitable common stock issued for future consulting services as prepaid expense in our consolidated balance sheets.
Income Taxes	'
	Income Taxes
	We account for income taxes under FASB ASC 740 “Income Taxes.” Under the asset and liability method of FASB ASC 740, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under FASB ASC 740, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period the enactment occurs. A valuation allowance is provided for certain deferred tax assets if it is more likely than not that we will not realize tax assets through future operations.
Earnings (Loss) per Share	'
	Earnings (Loss) per Share
	Basic loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares assumed to be outstanding during the period of computation.  Diluted loss per share is computed similar to basic loss per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential shares had been issued and if the additional common shares were dilutive.  Options and warrants to purchase approximately 9.3 million shares of common stock were outstanding at March 31, 2014.  There were no options or warrants outstanding at March 31, 2013. Dilutive equivalents were excluded from the computation of diluted loss per share due to the anti-dilutive effect on net loss per share.

	We have no items of other comprehensive income (loss) in any period presented. Therefore, net loss as presented in our Condensed Consolidated Statements of Operations equals comprehensive loss.
Recently Issued Accounting Pronouncements	'
	Recently Issued Accounting Pronouncements
	Effective January 1, 2014, we adopted FASB ASU 2013-07, Presentation of Financial Statements (Topic 205): Liquidation Basis of Accounting (“ASU 2013-07”). The amendments in ASU 2013-07 clarify when an entity should apply the liquidation basis of accounting and provide principles for the recognition and measurement of associated assets and liabilities. In accordance with the amendments, the liquidation basis is used when liquidation is imminent.  Liquidation is considered imminent when the likelihood is remote that the organization will return from liquidation and either: (a) a plan for liquidation is approved by the person or persons with the authority to make such a plan effective and the likelihood is remote that the execution of the plan will be blocked by other parties; or (b) a plan for liquidation is being imposed by other forces. The adoption of ASU 2013-07 did not have a material impact on our condensed consolidated financial statements.
	Effective January 1, 2014, we adopted FASB ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). The amendments in ASU 2013-11 clarify that an unrecognized tax benefit, or a portion of  an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed.  In situations where a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The adoption of ASU 2013-11 did not have a material impact on our condensed consolidated financial statements.
