Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	3. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Regulation S-X and do not include all the information and disclosures required by generally accepted accounting principles in the United States of America ( “GAAP” Principles of Consolidation The condensed consolidated financial statements include the accounts of Digital Power, its wholly-owned subsidiaries, DP Limited, Coolisys, Power-Plus and DP Lending and its majority-owned subsidiary, Microphase. All significant intercompany accounts and transactions have been eliminated in consolidation. Accounting Estimates The preparation of financial statements, in conformity with GAAP, requires management to make estimates, judgments and assumptions. The Company's management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Key estimates include acquisition accounting, fair value of certain financial instruments, reserve for trade receivables and inventories, carrying amounts of investments, accruals of certain liabilities including product warranties, and deferred income taxes and related valuation allowance. Investments in Debt and Equity Securities The Company classifies its investments in Avalanche International, Corp ( “AVLP” Investment in Debt and Equity Securities “ASC No. 320” Investment – Other “ASC No. 325” Revenue Recognition The Company generates revenues from the sale of its products through a direct and indirect sales force. Revenues from products are recognized in accordance with ASC No. 605, Revenue Recognition Warranty The Company offers a warranty period for all its products. Warranty periods range from one to two years depending on the product. The Company estimates the costs that may be incurred under its warranty and records a liability in the amount of such costs at the time product revenue is recognized. Factors that affect the Company's warranty liability include the number of units sold, historical rates of warranty claims and cost per claim. The Company periodically assesses the adequacy of its recorded warranty liability and adjusts the amounts as necessary. As of September 30, 2017 and December 31, 2016, the Company’s accrued warranty liability was $86. Common Stock Purchase Warrants and Other Derivative Financial Instruments The Company classifies common stock purchase warrants and other free standing derivative financial instruments as equity if the contracts (i) require physical settlement or net-share settlement or (ii) give the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). The Company classifies any contracts that (i) require net-cash settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside the control of the Company), (ii) give the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement), or (iii) contain reset provisions as either an asset or a liability. The Company assesses classification of its freestanding derivatives at each reporting date to determine whether a change in classification between assets and liabilities is required. The Company determined that certain freestanding derivatives, which principally consist of issuance of warrants to purchase shares of common in connection with convertible notes, units and to employees of the Company, satisfy the criteria for classification as equity instruments as these warrants do not contain cash settlement features or variable settlement provision that cause them to not be indexed to the Company’s own stock. Stock-Based Compensation The Company accounts for stock-based compensation in accordance with ASC No. 718, Compensation – Stock Compensation "ASC No. 718" The Company’s accounting policy for equity instruments issued to consultants and vendors in exchange for goods and services follows the provisions of ASC No. 505-50, Equity Based Payments to Non-Employees Convertible Instruments The Company accounts for hybrid contracts that feature conversion options in accordance with ASC No. 815, Derivatives and Hedging Activities “ASC No. 815” Conversion options that contain variable settlement features such as provisions to adjust the conversion price upon subsequent issuances of equity or equity linked securities at exercise prices more favorable than that featured in the hybrid contract generally result in their bifurcation from the host instrument. The Company accounts for convertible instruments, when the Company has determined that the embedded conversion options should not be bifurcated from their host instruments, in accordance with ASC No. 470-20, Debt with Conversion and Other Options “ASC No. 470-20” Comprehensive Loss The Company reports comprehensive loss in accordance with ASC No. 220, Comprehensive Income Fair value of Financial Instruments In accordance with ASC No. 820, Fair Value Measurements and Disclosures The guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors that market participants would use in valuing the asset or liability. The guidance establishes three levels of inputs that may be used to measure fair value: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or model-derived valuations. All significant inputs used in our valuations are observable or can be derived principally from or corroborated with observable market data for substantially the full term of the assets or liabilities Level 2 inputs also include quoted prices that were adjusted for security-specific restrictions which are compared to output from internally developed models such as a discounted cash flow models. Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The carrying amounts of financial instruments carried at cost, including cash and cash equivalents, trade receivables and trade receivable – related party, investments, notes receivable, trade payables and trade payables – related party approximate their fair value due to the short-term maturities of such instruments. As of September 30, 2017 and December 31, 2016, the fair value of the Company’s investments were $3,782 and $1,036, respectively, and were concentrated in debt and equity securities of AVLP, a related party (See Note 4), which are classified as available-for-sale investments. At September 30, 2017, the Company's investment in AVLP is comprised of convertible promissory notes of $3,670, net of unamortized discount, and marketable equity securities of $112. At December 31, 2016, the Company's investment in AVLP is comprised of convertible promissory notes of $952, net of unamortized discount, and marketable equity securities of $84. For investments in marketable equity securities, the Company took into consideration general market conditions, the duration and extent to which the fair value is below cost, and the Company’s ability and intent to hold the investment for a sufficient period of time to allow for recovery of value in the foreseeable future. As a result of this analysis, the Company has determined that its cost basis in AVLP equitable securities approximates the current fair value. Consistent with the guidance at ASC No. 835, the Company’s presumption is that the fair value of its convertible promissory notes in AVLP have a present value equivalent to the cash proceeds exchanged. Further, the discount shall be reported in the balance sheet as a direct deduction from the face amount of the convertible promissory notes. Thus, the Company has determined that the amortized cost of its convertible promissory notes approximates fair value and are subject to a periodic impairment review. The interest income, including amortization of the discount arising at acquisition, for the convertible promissory notes are included in earnings. In the future, if the Company does not expect to recover the entire amortized cost basis, the Company shall recognize other-than-temporary impairments in other comprehensive income (loss). During 2017, the Company purchased at the market shares of common stock of three companies for a total cost of $25. In accordance with ASC No. 320-10, these investments are accounted for pursuant to the fair value method based upon the closing market prices of common stock for these three companies at September 30, 2017. The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following table sets forth the Company’s financial instruments that were measured at fair value on a recurring basis by level within the fair value hierarchy: Fair Value Measurement at September 30, 2017 Total Level 1 Level 2 Level 3 Investments – AVLP – a related party $ 3,782 $ 112 $ 3,670 $ — Investments in other companies $ 25 $ 25 $ — $ — Fair Value Measurement at December 31, 2016 Total Level 1 Level 2 Level 3 Investments – AVLP – a related party $ 1,036 $ 84 $ 952 $ — We assess the inputs used to measure fair value using a three-tier hierarchy based on the extent to which inputs used in measuring fair value are observable in the market: ● Level 1 – inputs include quoted prices for identical instruments and are the most observable. ● Level 2 – inputs include quoted prices for similar assets and observable inputs such as interest rates, currency exchange rates and yield curves. ● Level 3 – inputs are not observable in the market and include management’s judgments about the assumptions market participants would use in pricing the asset or liability. Debt Discounts The Company accounts for debt discount according to ASC No. 470-20, Debt with Conversion and Other Options Net Loss per Share Net loss per share is computed by dividing the net loss to common stockholders by the weighted average number of common shares outstanding. The calculation of the basic and diluted earnings per share is the same for all periods presented, as the effect of the potential common stock equivalents is anti-dilutive due to the Company’s net loss position for all periods presented. The Company has included 317,460 warrants, with an exercise price of $.01, in its earnings per share calculation for the three and nine months ended September 30, 2017. Anti-dilutive securities consisted of the following at September 30, 2017 2016 Stock options 2,891,000 1,001,000 Warrants 10,233,199 — Convertible notes 3,157,576 — Conversion of preferred stock 4,606,131 — Total 20,887,906 1,001,000 At September 30, 2017, the 20,887,906 of potential common stock equivalents included 6,926,095 in warrants, convertible notes and preferred stock in which the holders are contractually prohibited from exercising or converting the warrants, convertible notes and preferred stock into shares of the Company’s common stock. The restriction shall remain until shareholder approval is received. Subsequent to September 30, 2017, the Company entered into agreements to issue an additional 2,042,239 shares of common stock and issued convertible notes and warrants that when exercised would result in the issuance of an additional 2,274,800 shares of common stock. As a result, on November 2, 2017, if all of the potential common stock equivalents in which there are no contractual restrictions upon exercise were converted into shares of the Company’s common stock it would exceed the Company’s authorized shares of common stock. Recently Issued Accounting Standards The Company has considered all other recently issued accounting standards and does not believe the adoption of such standards will have a material impact on its condensed consolidated financial statements.

On September 6, 2017, the Company and AVLP entered into a Loan and Security Agreement ( “AVLP Loan Agreement” In consideration of entering into the AVLP Loan Agreement, the Company and AVLP cancelled the AVLP Notes and consolidated the AVLP Notes and prior advances totaling $3,309 plus original issue discount of $165 and issued a new Convertible Promissory Note in the aggregate principal amount of $3,474 (the “New Note” The Warrant entitles the Company to purchase up to 6,948,800 shares of AVLP common stock at an exercise price of $0.50 per share for a period of five years. The exercise price of $0.50 is subject to adjustment for customary stock splits, stock dividends, combinations or similar events. The Warrant may be exercised for cash or on a cashless basis. The original issue discount of $165 on the New Note is being amortized as interest income through the maturity date using the interest rate method. During the three and nine months ended September 30, 2017, the Company recorded $18 and $38, respectively, of interest income for the discount accretion. As of September 30, 2017, and December 31, 2016, the Company recorded contractual interest receivable attributed to the AVLP Notes and AVLP Loan Agreement of $208 and $13, respectively.

Subsequent to quarter-end, the closing market price of AVLP’s common stock was in the range of $0.51 and $ 0.85 and due to the illiquidity and significant volatility of AVLP’s common stock, the Company has determined that its cost basis in AVLP common stock approximates the current fair value. The Company has concluded that indicators of impairment, including those described in ASC No. 320-10-35-27, do not currently exist for the Company’s investment in debt and equity securities of AVLP.

STOCK-BASED COMPENSATION	6. STOCK-BASED COMPENSATION Under the Company's 2016 Stock Incentive Plan (the “2016 Plan” “2012 Plan” “Plans” “2002 Plan” Options granted under the Plans have an exercise price equal to or greater than the fair value of the underlying common stock at the date of grant and become exercisable based on a vesting schedule determined at the date of grant. Typically, options granted generally become fully vested after four years. Any options that are forfeited or cancelled before expiration become available for future grants. The options expire between 5 and 10 years from the date of grant. Restricted stock awards granted under the Plans are subject to a vesting period determined at the date of grant. As of September 30, 2017, an aggregate of 1,350,832 of the Company's options are still available for future grant. During the three and nine months ended September 30, 2017, the Company granted 50,000 and 560,000 options, respectively, from the Plans to its employees at an average exercise price of $0.61 per share. These options become fully vested after four years. The Company estimated that the grant date fair value of these options was $251, which is being recognized as stock-based compensation expense over the requisite four-year service period. During the three and nine months ended September 30, 2017, the Company also issued 380,645 and 1,336,798, respectively, shares of common stock to its consultants and service providers pursuant to the 2016 Plan. The Company estimated that the grant date fair value of these shares of common stock was $742, which was determined from the closing price of the Company’s common stock on the date of issuance. The Company did not grant any options or restricted stock awards during the three and nine months ended September 30, 2016. The Company has valued the options at their date of grant utilizing the Black-Scholes option pricing model. This model is dependent upon several variables such as the options’ term, exercise price, current stock price, risk-free interest rate estimated over the expected term and estimated volatility of our stock over the expected term of the options. The risk-free interest rate used in the calculations is based on the implied yield available on U.S. Treasury issues with an equivalent term approximating the expected life of the options as calculated using the simplified method. The estimated volatility was determined based on the historical volatility of our common stock. During the nine months ended September 30, 2017, the Company estimated the fair value of stock options granted using the Black-Scholes option pricing model with the following weighted average assumptions: September 30, 2017 Weighted average risk free interest rate 1.73% — 2.14 % Weighted average life (in years) 5.0 Volatility 98.41% — 107.22 % Expected dividend yield 0 % Weighted average grant-date fair value per share of options granted $ 0.45 Outstanding Exercisable Weighted Average Weighted Weighted Remaining Average Average Exercise Number Contractual Exercise Number Exercise Price Outstanding Life (Years) Price Exercisable Price $0.57 - $0.79 2,425,000 9.14 $ 0.66 1,249,167 $ 0.66 $1.10 - $1.32 25,000 6.10 $ 1.28 20,000 $ 1.27 $1.51 - $1.69 441,000 5.11 $ 1.61 378,500 $ 1.60 $0.57 - 1.69 2,891,000 8.50 $ 1.10 1,647,667 $ 0.88 The total stock-based compensation expense related to stock options and restricted stock awards to the Company’s employees, consultants and directors, included in reported net loss Three Months Ended Nine Months Ended Sept. 30, 2017 Sept. 30, 2016 Sept. 30, 2017 Sept. 30, 2016 Cost of revenues $ 2 $ 1 $ 6 $ 5 Engineering and product development 6 1 20 3 Selling and marketing 8 5 18 13 General and administrative 349 35 1,017 108 Stock-based compensation from Plans 365 42 1,061 129 Stock-based compensation from issuances outside of Plans 152 — 208 — Total stock-based compensation $ 517 $ 42 $ 1,269 $ 129 The combination of stock-based compensation of $1,061 from the issuances of equity based awards pursuant to the Plans and stock-based compensation attributed to restricted stock awards of $130 and warrants and options of $78, which were issued outside of the Plans, resulted in aggregate stock-based compensation of $1,269 during the nine months ended September 30, 2017. During the three months ended September 30, 2017, aggregate stock-based compensation was $517, which consisted of $365 from the issuances of equity based awards pursuant to the Plans and stock-based compensation attributed to restricted stock award of $120 warrants and options of $32, which were issued outside of the Plans. During the three and nine months ended September 30, 2016, the only stock-based compensation expense was from issuances pursuant to the Plans. A summary of option activity under the Company's stock option plans as of September 30, 2017, and changes during the nine months ended are as follows: Outstanding Options Weighted Weighted Average Shares Average Remaining Aggregate Available Number Exercise Contractual Intrinsic for Grant of Shares Price Life (years) Value December 31, 2016 3,247,630 2,331,000 $ 0.83 9.08 $ 0 Restricted stock awards (1,336,798 ) Grants (510,000 ) 560,000 $ 0.61 September 30, 2017 1,350,832 2,891,000 $ 0.81 8.50 $ 0 The aggregate intrinsic value in the table above represents the total intrinsic value (the difference between the Company's closing stock price on September 30, 2017, $0.55 and the exercise price, multiplied by the number of in-the-money-options). As of September 30, 2017, there was $425 of unrecognized compensation cost related to non-vested stock-based compensation arrangements granted under the Company's stock option plans. That cost is expected to be recognized over a weighted average period of 2.3 years.

Each share of Series B Preferred Stock shall have the right to receive dividends equal to one ten millionth (0.0000001) of earnings before interest, taxes, depreciation, amortization and stock-based compensation ( “EBITDAS” At such time as (i) all shares of common stock issuable upon conversion of all outstanding shares of Series B Preferred Stock (the “Conversion Shares” In addition, for each share of Series B Preferred Stock purchased, Philou will receive warrants to purchase shares of common stock in a number equal to the stated value of each share of Series B Preferred Stock purchased divided by $0.70, at an exercise price equal to $0.70 per share of common stock. The warrants do not require a net cash-settlement or provide the holder with a choice of net-cash settlement. The warrants also do not contain a variable settlement provision. Accordingly, any warrants issued to Philou pursuant to the terms of the Preferred Stock Purchase Agreement shall be classified as equity instruments. Further, Philou shall have the right to participate in the Company’s future financings under substantially the same terms and conditions as other investors in those respective financings in order to maintain its then percentage ownership interest in the Company.

As the effective conversion price of the Series B Convertible Preferred Stock on a converted basis was below the market price of the Company’s common stock on the date of issuance, it was determined that these discounts represent contingent beneficial conversion features, which were valued at $265 based on the difference between the effective conversion price and the market price of the Company’s common stock on the date of issuance. The Company, however, is prohibited from issuing shares of common stock pursuant to the Series B Convertible Preferred Stock unless stockholder approval of such issuance of securities is obtained as required by applicable NYSE MKT listing rules.

As the effective conversion price of the Series C Convertible Preferred Stock on a converted basis was below the market price of the Company’s common stock on the date of issuance, it was determined that these discounts represent beneficial conversion features, which were valued at $371 and recognized as a deemed dividend, based on the difference between the effective conversion price and the market price of the Company’s common stock on the date of issuance. Each share of Series C Preferred Stock has the right to receive dividends equal $0.24 per share per annum as declared by the Company’s Board of Directors.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements include the accounts of Digital Power, its wholly-owned subsidiaries, DP Limited, Coolisys, Power-Plus and DP Lending and its majority-owned subsidiary, Microphase. All significant intercompany accounts and transactions have been eliminated in consolidation.
Accounting Estimates	Accounting Estimates The preparation of financial statements, in conformity with GAAP, requires management to make estimates, judgments and assumptions. The Company's management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Key estimates include acquisition accounting, fair value of certain financial instruments, reserve for trade receivables and inventories, carrying amounts of investments, accruals of certain liabilities including product warranties, and deferred income taxes and related valuation allowance.
Investments in Debt and Equity Securities	Investments in Debt and Equity Securities The Company classifies its investments in Avalanche International, Corp ( “AVLP” Investment in Debt and Equity Securities “ASC No. 320” Investment – Other “ASC No. 325”
Revenue Recognition	Revenue Recognition The Company generates revenues from the sale of its products through a direct and indirect sales force. Revenues from products are recognized in accordance with ASC No. 605, Revenue Recognition
Warranty	Warranty The Company offers a warranty period for all its products. Warranty periods range from one to two years depending on the product. The Company estimates the costs that may be incurred under its warranty and records a liability in the amount of such costs at the time product revenue is recognized. Factors that affect the Company's warranty liability include the number of units sold, historical rates of warranty claims and cost per claim. The Company periodically assesses the adequacy of its recorded warranty liability and adjusts the amounts as necessary. As of September 30, 2017 and December 31, 2016, the Company’s accrued warranty liability was $86.
Common Stock Purchase Warrants and Other Derivative Financial Instruments	Common Stock Purchase Warrants and Other Derivative Financial Instruments The Company classifies common stock purchase warrants and other free standing derivative financial instruments as equity if the contracts (i) require physical settlement or net-share settlement or (ii) give the Company a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement). The Company classifies any contracts that (i) require net-cash settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside the control of the Company), (ii) give the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement), or (iii) contain reset provisions as either an asset or a liability. The Company assesses classification of its freestanding derivatives at each reporting date to determine whether a change in classification between assets and liabilities is required. The Company determined that certain freestanding derivatives, which principally consist of issuance of warrants to purchase shares of common in connection with convertible notes, units and to employees of the Company, satisfy the criteria for classification as equity instruments as these warrants do not contain cash settlement features or variable settlement provision that cause them to not be indexed to the Company’s own stock.
Stock Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation in accordance with ASC No. 718, Compensation – Stock Compensation "ASC No. 718" The Company’s accounting policy for equity instruments issued to consultants and vendors in exchange for goods and services follows the provisions of ASC No. 505-50, Equity Based Payments to Non-Employees
Convertible Instruments	Convertible Instruments The Company accounts for hybrid contracts that feature conversion options in accordance with ASC No. 815, Derivatives and Hedging Activities “ASC No. 815” Conversion options that contain variable settlement features such as provisions to adjust the conversion price upon subsequent issuances of equity or equity linked securities at exercise prices more favorable than that featured in the hybrid contract generally result in their bifurcation from the host instrument. The Company accounts for convertible instruments, when the Company has determined that the embedded conversion options should not be bifurcated from their host instruments, in accordance with ASC No. 470-20, Debt with Conversion and Other Options “ASC No. 470-20”
Comprehensive Loss	Comprehensive Loss The Company reports comprehensive loss in accordance with ASC No. 220, Comprehensive Income
Fair value of Financial Instruments	Fair value of Financial Instruments In accordance with ASC No. 820, Fair Value Measurements and Disclosures The guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors that market participants would use in valuing the asset or liability. The guidance establishes three levels of inputs that may be used to measure fair value: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or model-derived valuations. All significant inputs used in our valuations are observable or can be derived principally from or corroborated with observable market data for substantially the full term of the assets or liabilities Level 2 inputs also include quoted prices that were adjusted for security-specific restrictions which are compared to output from internally developed models such as a discounted cash flow models. Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The carrying amounts of financial instruments carried at cost, including cash and cash equivalents, trade receivables and trade receivable – related party, investments, notes receivable, trade payables and trade payables – related party approximate their fair value due to the short-term maturities of such instruments. As of September 30, 2017 and December 31, 2016, the fair value of the Company’s investments were $3,782 and $1,036, respectively, and were concentrated in debt and equity securities of AVLP, a related party (See Note 4), which are classified as available-for-sale investments. At September 30, 2017, the Company's investment in AVLP is comprised of convertible promissory notes of $3,670, net of unamortized discount, and marketable equity securities of $112. At December 31, 2016, the Company's investment in AVLP is comprised of convertible promissory notes of $952, net of unamortized discount, and marketable equity securities of $84. For investments in marketable equity securities, the Company took into consideration general market conditions, the duration and extent to which the fair value is below cost, and the Company’s ability and intent to hold the investment for a sufficient period of time to allow for recovery of value in the foreseeable future. As a result of this analysis, the Company has determined that its cost basis in AVLP equitable securities approximates the current fair value. Consistent with the guidance at ASC No. 835, the Company’s presumption is that the fair value of its convertible promissory notes in AVLP have a present value equivalent to the cash proceeds exchanged. Further, the discount shall be reported in the balance sheet as a direct deduction from the face amount of the convertible promissory notes. Thus, the Company has determined that the amortized cost of its convertible promissory notes approximates fair value and are subject to a periodic impairment review. The interest income, including amortization of the discount arising at acquisition, for the convertible promissory notes are included in earnings. In the future, if the Company does not expect to recover the entire amortized cost basis, the Company shall recognize other-than-temporary impairments in other comprehensive income (loss). During 2017, the Company purchased at the market shares of common stock of three companies for a total cost of $25. In accordance with ASC No. 320-10, these investments are accounted for pursuant to the fair value method based upon the closing market prices of common stock for these three companies at September 30, 2017. The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following table sets forth the Company’s financial instruments that were measured at fair value on a recurring basis by level within the fair value hierarchy: Fair Value Measurement at September 30, 2017 Total Level 1 Level 2 Level 3 Investments – AVLP – a related party $ 3,782 $ 112 $ 3,670 $ — Investments in other companies $ 25 $ 25 $ — $ — Fair Value Measurement at December 31, 2016 Total Level 1 Level 2 Level 3 Investments – AVLP – a related party $ 1,036 $ 84 $ 952 $ — We assess the inputs used to measure fair value using a three-tier hierarchy based on the extent to which inputs used in measuring fair value are observable in the market: ● Level 1 – inputs include quoted prices for identical instruments and are the most observable. ● Level 2 – inputs include quoted prices for similar assets and observable inputs such as interest rates, currency exchange rates and yield curves. ● Level 3 – inputs are not observable in the market and include management’s judgments about the assumptions market participants would use in pricing the asset or liability.
Debt Discounts	Debt Discounts The Company accounts for debt discount according to ASC No. 470-20, Debt with Conversion and Other Options
Net Loss per Share	Net Loss per Share Net loss per share is computed by dividing the net loss to common stockholders by the weighted average number of common shares outstanding. The calculation of the basic and diluted earnings per share is the same for all periods presented, as the effect of the potential common stock equivalents is anti-dilutive due to the Company’s net loss position for all periods presented. The Company has included 317,460 warrants, with an exercise price of $.01, in its earnings per share calculation for the three and nine months ended September 30, 2017. Anti-dilutive securities consisted of the following at September 30, 2017 2016 Stock options 2,891,000 1,001,000 Warrants 10,233,199 — Convertible notes 3,157,576 — Conversion of preferred stock 4,606,131 — Total 20,887,906 1,001,000 At September 30, 2017, the 20,887,906 of potential common stock equivalents included 6,926,095 in warrants, convertible notes and preferred stock in which the holders are contractually prohibited from exercising or converting the warrants, convertible notes and preferred stock into shares of the Company’s common stock. The restriction shall remain until shareholder approval is received. Subsequent to September 30, 2017, the Company entered into agreements to issue an additional 2,017,239 shares of common stock and issued convertible notes and warrants that when exercised would result in the issuance of an additional 2,274,800 shares of common stock. As a result, on November 2, 2017, if all of the potential common stock equivalents in which there are no contractual restrictions upon exercise were converted into shares of the Company’s common stock it would exceed the Company’s authorized shares of common stock.
Recently Issued Accounting Standards	Recently Issued Accounting Standards The Company has considered all other recently issued accounting standards and does not believe the adoption of such standards will have a material impact on its condensed consolidated financial statements.

[1]	Between May 5, 2017 and June 30, 2017, Digital Power received additional short-term loans of $140 from four accredited investors, of which $75 was from the Company's corporate counsel, a related party. As additional consideration, the investors received five-year warrants to purchase 224,371 shares of common stock at a weighted average exercise price of $0.77 per share. The warrants are exercisable commencing six months after the issuance date and are subject to certain beneficial ownership limitations. The exercise price of these warrants is subject to adjustment for customary stock splits, stock dividends, combinations and other standard anti-dilution events. The warrants may be exercised for cash or on a cashless basis. During the quarter ended June 30, 2017, the Company recorded debt discount in the amount of $95 based on the estimated fair value of these warrants. The Company computed the fair value of these warrants using the Black-Scholes option pricing model. As a result of the short-term feature of these loans and advances, the debt discount was amortized as non-cash interest expense upon issuance of the warrants using the effective interest method.
[2]	In December 2016, Microphase issued $705 in 10% short-term promissory notes to nineteen accredited investors which, after deducting $71 of placement fees to its selling agent, Spartan Capital Securities, LLC ("Spartan"), resulted in $634 in net proceeds to Microphase (the "10% Short-Term Notes"). The 10% Short-Term Notes are due one year from the date of issuance. The amount due pursuant to the 10% Short-Term Notes is equal to the entire original principal amount multiplied by 125% (the "Loan Premium") plus accrued interest. During the three months ended September 30, 2017 and the period June 3, 2017 to September 30, 2017, Microphase incurred $19 and $25, respectively, of interest on these 10% short-term promissory notes. Concurrently, Microphase entered into a one-year agreement with Spartan for investment banking services which provided for: (i) $120 of consulting fees that were paid in cash from the proceeds of the 10% Short-Term Notes; and (ii) if Microphase completes an initial public offering, $90 payable in shares of Microphase common stock. As of September 30, 2017, accrued interest on the 10% Short-Term Notes was $237.
[3]	On June 2, 2017, pursuant to the terms of the Share Exchange Agreement and in consideration of legal services, Microphase issued a $450 8% promissory note with a maturity date of November 25, 2017 to Lucosky Brookman, LLP (the "Lucosky Note"). In conjunction with the issuance of the Lucosky Note, the Company issued Lucosky Brookman 10,000 shares of redeemable convertible Series E preferred stock (the "Series E Preferred Stock") with a stated value of $45 per share as an alternative to providing a guarantee for the amount of the Lucosky Note. The Company, at its option, may redeem for cash, in whole or in part, at any time and from time to time, the shares of Series E Preferred Stock at the time outstanding, upon written notice to the holder of the shares, at a cash redemption price equal to $45 multiplied by the number of shares being redeemed. Any such optional redemption by the Company shall be credited against the Lucosky Note. During the three months ended September 30, 2017 and the period June 3, 2017 to September 30, 2017, Microphase incurred $3 and $6, respectively, of interest on the Lucosky Note. As of September 30, 2017, accrued interest on the Lucosky Note was $6.
[4]	At September 30, 2017, Microphase had guaranteed the repayment of two equity lines of credit in the aggregate amount of $304 with Wells Fargo Bank, NA ("Wells Fargo") (collectively, the "Wells Fargo Notes"). Microphase had previously guaranteed the payment under the first Wells Fargo equity line during 2008, the proceeds of which Microphase had received from a concurrent loan from Edson Realty Inc., a related party owned real estate holding company. As of September 30, 2017, the first line of credit, which is secured by residential real estate owned by a former officer, had an outstanding balance of $214, with an annual interest rate of 4.00%. Microphase had guaranteed the payment under the second Wells Fargo equity line in 2014. Microphase had received working capital loans from the former CEO from funds that were drawn against the second Wells Fargo equity line. As of September 30, 2017, the second line of credit, secured by the former CEO's principal residence, had an outstanding balance of $90, with an annual interest rate of 3.00%. During the three months ended September 30, 2017 and the period June 3, 2017 to September 30, 2017, Microphase incurred $3 and $4, respectively, of interest on the Wells Fargo Notes.
[5]	In August 2016, Microphase received a $300 loan pursuant to the State of Connecticut Small Business Express Job Creation Incentive Program which is administered through the Department of Economic and Community Development ("DECD") (the "DECD Note"). The DECD Note bears interest at a rate of 3% per annum and is due in August 2026. Payment of principal and interest is deferred during the initial year and commencing on the thirteenth month, payable in equal monthly installments over the remaining term. During the three months ended September 30, 2017 and the period June 3, 2017 to September 30, 2017, Microphase incurred $3 of interest on the DECD Note. In conjunction with the DECD Note, Microphase was awarded a Small Business Express Matching Grant of $100. State grant funding requires a dollar for dollar match on behalf of Microphase. As of June 30, 2017, the Company has utilized $18 of the grant and the balance of $82 is reported within deferred revenue.
[6]	In December 2016, Microphase utilized a $20 overdraft credit line at People's United Bank with an annual interest rate of 15%. As of September 30, 2017, the balance of that overdraft credit line was $19.
[7]	At September 30, 2017, Power-Plus had guaranteed the repayment of two lines of credit in the aggregate amount of $182 with Bank of America NA ("B of A") and Wells Fargo (collectively, the "Power-Plus Lines"). As of September 30, 2017, the B of A line of credit had an outstanding balance of $107, with an annual interest rate of 6.25%. As of September 30, 2017, the Wells Fargo line of credit had an outstanding balance of $75, with an annual interest rate of 10.00%. During the period September 2 to September 30, 2017, Power-Plus incurred $1 of interest on the Power-Plus Lines.
[8]	Pursuant to the terms of the Purchase Agreement with Power-Plus, the Company entered into a two-year promissory note in the amount of $255 payable to the former owner as part of the purchase consideration. The $255 note is payable in 24 equal monthly installments.

Description of conversion		An additional $75 in short-term loans from the Company’s corporate counsel was converted into the Company’s equity securities; $52 was converted into one of the Series C Units and $23 was converted into the Company’s common stock. The Company did not record any additional interest expense as a result of the extinguishment of $130 in short-term loans since the carrying amount of the short-term loans was equivalent to the fair value of the consideration transferred, which was determined from the closing price of the Company’s equity securities on the date of extinguishment. During the three months ended September 30, 2017, the Company also repaid $30 in short-term loans.

[5]	In August 2016, Microphase received a $300 loan pursuant to the State of Connecticut Small Business Express Job Creation Incentive Program which is administered through the Department of Economic and Community Development ("DECD") (the "DECD Note"). The DECD Note bears interest at a rate of 3% per annum and is due in August 2026. Payment of principal and interest is deferred during the initial year and commencing on the thirteenth month, payable in equal monthly installments over the remaining term. During the three months ended September 30, 2017 and the period June 3, 2017 to September 30, 2017, Microphase incurred $3 of interest on the DECD Note. In conjunction with the DECD Note, Microphase was awarded a Small Business Express Matching Grant of $100. State grant funding requires a dollar for dollar match on behalf of Microphase.

[1]	On December 29, 2016, the Company entered into an agreement with MCKEA Holdings, LLC ("MCKEA"). MCKEA is the majority member of Philou Ventures, LLC, which is the Company's controlling shareholder. Kristine L. Ault, a director and the wife of Milton C. Ault III, Executive Chairman of the Company's Board of Directors, is the manager and owner of MCKEA, for a demand promissory note (The "MCKEA Note") in the amount of $250 bearing interest at the rate of 6% per annum on unpaid principal. The MCKEA Note may be prepaid, in whole or in part, without penalty, at the option of the Company and without the consent of MCKEA. As of December 31, 2016, no interest was accrued on the MCKEA Note. On March 24, 2017, the MCKEA Note was cancelled to purchase the Company's Series B Preferred Stock pursuant to the terms of the Preferred Stock Purchase Agreement entered into on March 9, 2017 (See Note 14). Since there was no difference between the reacquisition price and the net carrying value of the cancelled debt, no gain or loss was recognized as a result of this transaction.
[2]	Microphase is a party to several notes payable agreements with seven of its past officers, employees and their family members. As of September 30, 2017, the aggregate outstanding balance pursuant to these notes payable agreements, inclusive of $87 of accrued interest, was $493, with annual interest rates ranging between 3.00% and 6.00%. During the three months ended September 30, 2017 and the period June 3, 2017 to September 30, 2017, Microphase incurred $7 of interest on these notes payable agreements. In July 2016, one of these noteholders initiated litigation to collect the balance owed under the terms of his respective agreement. At September 30, 2017, the outstanding principal balance and accrued interest owed under this particular agreement was $162.

Description of preferred stock		Each share of Series C Preferred Stock has a stated value of $2.40 per share. Each share of Series C Preferred Stock may be convertible at the holder’s option into shares of Common Stock of the Company at a conversion price of $0.60 per share, which, currently, represents four shares of Common Stock. The conversion price is subject to standard anti-dilution provisions in connection with any stock split, stock dividend, subdivision or similar reclassification of the Common Stock. Each share of Series C Preferred stock is mandatorily converted into shares of Common Stock based on the then conversion price in effect in the event that the Company’s Common Stock closing price exceeds $1.20 per share for 20 consecutive trading days. As the effective conversion price of the Series C Convertible Preferred Stock on a converted basis was below the market price of the Company’s common stock on the date of issuance, it was determined that these discounts represent beneficial conversion features, which were valued at $371 and recognized as a deemed dividend, based on the difference between the effective conversion price and the market price of the Company’s common stock on the date of issuance.

[1]	On June 2, 2017, pursuant to the terms of the Share Exchange Agreement and in consideration of legal services, Microphase issued a $450 8% promissory note with a maturity date of November 25, 2017 to Lucosky Brookman, LLP (the "Lucosky Note"). In conjunction with the issuance of the Lucosky Note, the Company issued Lucosky Brookman 10,000 shares of redeemable convertible Series E preferred stock (the "Series E Preferred Stock") with a stated value of $45 per share as an alternative to providing a guarantee for the amount of the Lucosky Note. The Company, at its option, may redeem for cash, in whole or in part, at any time and from time to time, the shares of Series E Preferred Stock at the time outstanding, upon written notice to the holder of the shares, at a cash redemption price equal to $45 multiplied by the number of shares being redeemed. Any such optional redemption by the Company shall be credited against the Lucosky Note. During the three months ended September 30, 2017 and the period June 3, 2017 to September 30, 2017, Microphase incurred $3 and $6, respectively, of interest on the Lucosky Note. As of September 30, 2017, accrued interest on the Lucosky Note was $6.
