Significant Accounting Policies [Text Block]	Note 1 Business Qualstar Corporation and Subsidiary (collectively, “Qualstar”, the “Company”, “we”, “us” or “our”), was incorporated in California in 1984. N2Power 1995, July 2002, N2Power, N2Power We design our products at our location in California, and we sell our products globally through authorized resellers and directly to original equipment manufacturers (“OEMs”). N2Power June 30, 2014, The consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiary in Singapore. All significant intercompany accounts and transactions have been eliminated in consolidation. On January 4, 2016, June 30 December 31. twelve December 31, 2015. July 1, 2015 December 31, 2015, twelve December 31, 2016, twelve December 31, 2015, Accounting Principles The consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Estimates and Assumptions Preparing financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses. Examples include estimates of loss contingencies, product life cycles and inventory obsolescence, bad debts, sales returns, warranty costs, share-based compensation forfeiture rates, the potential outcome of future tax consequences of events that have been recognized in our consolidated financial statements or tax returns, and determining when investment impairments are other-than-temporary. Actual results and outcomes may Revenue Recognition We recognize revenue when there is persuasive evidence that an arrangement exists, title and risk of loss have passed, delivery has occurred or the services have been rendered, the sales price is fixed or determinable and collection of the related receivable is reasonably assured. Title and risk of loss generally pass to our customers upon shipment. In limited circumstances where either title or risk of loss pass upon destination or acceptance or when collection is not reasonably assured, we defer revenue recognition until such events occur. In general, customers are allowed to return the product, free of penalty, within thirty We record an allowance for estimated sales returns based on past experience and current knowledge of our customer base. Our experience has been such that only a very small percentage of products are returned. Should our experience change, however, we may Revenue for established products that have previously satisfied a customer’s acceptance requirements and provide for full payment tied to shipment is generally recognized upon shipment and passage of title. In limited cases where a prior history of customer acceptance cannot be demonstrated or sales where customer payment dates are not determinable or when collection is not reasonably assured, revenue is deferred until customer acceptance occurs or payment has been received. On the limited shipments where sales are not recognized, gross profit is generally recorded as deferred profit in our balance sheet representing the difference between the receivable recorded and the inventory shipped. At December 31, 2016, $892 ,000 no December 31, 2015, $1,098,000 no Cash and Cash Equivalents Qualstar classifies as cash equivalents only cash and those investments that are highly liquid, interest-earning investments with original maturities of three Restricted Cash At December 31, 2016 2015, $100,000 Concentration of Credit Risk, Other Concentration Risks and Significant Customers Qualstar sells its products primarily through value added resellers located worldwide. Ongoing credit evaluations of customers’ financial condition are performed by Qualstar, and generally, collateral is not required. Potential uncollectible accounts have been provided for in the financial statements. We are exposed to foreign currency and interest rate risks. Our interest income is sensitive to changes in the general level of U.S. interest rates, particularly since all of our investments are in US fixed income securities. We have no outstanding debt nor do we utilize auction rate securities or derivative financial instruments in our investment portfolio. Cash and other investments may Our financial results could be affected by changes in foreign currency exchange rates or weak economic conditions in foreign markets. As all sales are currently made in U.S. dollars, a strengthening of the dollar could make our products less competitive in foreign markets. Sales outside North America represented approximately 46.1% twelve December 31, 2016, 50.3% twelve December 31, 2015, 41.9% six December 31, 2015, 54.0% twelve June 30, 2015.

Share-Based Compensation Share-based compensation cost is measured at the grant date based on fair value of the award and is recognized as expense over the applicable vesting period of the stock award (generally four Income Taxes Income taxes are accounted for using the liability method. Under this method, deferred tax liabilities and assets are recognized for the expected future tax consequences of temporary differences between the financial statement and tax bases of assets and liabilities, and for the expected future tax benefit to be derived from tax credits and loss carry forwards. Current income tax expense or benefit represents the amount of income taxes expected to be payable or refundable for the current year. A valuation allowance is established when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Comprehensive Loss Comprehensive loss includes unrealized gains and losses on debt and equity securities classified as available-for-sale and included as a component of shareholders’ equity. Net Loss per Share Basic net loss per share has been computed by dividing net loss by the weighted average number of common shares outstanding. Diluted net loss per share has been computed by dividing net loss by the weighted average common shares outstanding plus dilutive securities or other contracts to issue common stock as if these securities were exercised or converted to common stock.

The fair value of each option award is estimated on the date of grant using the Black-Scholes option valuation model that uses the assumptions, such as volatility, expected term and risk-free interest rate. Expected volatilities are based on the historical volatility of the Company’s stock. The Company uses historical data to estimate option exercise and employee termination in determining forfeiture rates and evaluates separate groups of employees by functional area that have similar historical exercise behavior. The expected term of options granted is estimated based on the vesting term of the award, historical employee exercise behavior, expected volatility of the Company’s stock and an employee’s average length of service. The risk-free interest rate used in this model correlates to a U.S. constant rate Treasury security with a contractual life that approximates the expected term of the option award.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Accounting Principles The consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).
Use of Estimates, Policy [Policy Text Block]	Estimates and Assumptions Preparing financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses. Examples include estimates of loss contingencies, product life cycles and inventory obsolescence, bad debts, sales returns, warranty costs, share-based compensation forfeiture rates, the potential outcome of future tax consequences of events that have been recognized in our consolidated financial statements or tax returns, and determining when investment impairments are other-than-temporary. Actual results and outcomes may
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition We recognize revenue when there is persuasive evidence that an arrangement exists, title and risk of loss have passed, delivery has occurred or the services have been rendered, the sales price is fixed or determinable and collection of the related receivable is reasonably assured. Title and risk of loss generally pass to our customers upon shipment. In limited circumstances where either title or risk of loss pass upon destination or acceptance or when collection is not reasonably assured, we defer revenue recognition until such events occur. In general, customers are allowed to return the product, free of penalty, within thirty We record an allowance for estimated sales returns based on past experience and current knowledge of our customer base. Our experience has been such that only a very small percentage of products are returned. Should our experience change, however, we may Revenue for established products that have previously satisfied a customer’s acceptance requirements and provide for full payment tied to shipment is generally recognized upon shipment and passage of title. In limited cases where a prior history of customer acceptance cannot be demonstrated or sales where customer payment dates are not determinable or when collection is not reasonably assured, revenue is deferred until customer acceptance occurs or payment has been received. On the limited shipments where sales are not recognized, gross profit is generally recorded as deferred profit in our balance sheet representing the difference between the receivable recorded and the inventory shipped. At December 31, 2016, $892 ,000 December 31, 2015, $1,098,000

Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentration of Credit Risk, Other Concentration Risks and Significant Customers Qualstar sells its products primarily through value added resellers located worldwide. Ongoing credit evaluations of customers’ financial condition are performed by Qualstar, and generally, collateral is not required. Potential uncollectible accounts have been provided for in the financial statements. We are exposed to foreign currency and interest rate risks. Our interest income is sensitive to changes in the general level of U.S. interest rates, particularly since all of our investments are in US fixed income securities. We have no outstanding debt nor do we utilize auction rate securities or derivative financial instruments in our investment portfolio. Cash and other investments may Our financial results could be affected by changes in foreign currency exchange rates or weak economic conditions in foreign markets. As all sales are currently made in U.S. dollars, a strengthening of the dollar could make our products less competitive in foreign markets.

Income Tax, Policy [Policy Text Block]	Income Taxes Income taxes are accounted for using the liability method. Under this method, deferred tax liabilities and assets are recognized for the expected future tax consequences of temporary differences between the financial statement and tax bases of assets and liabilities, and for the expected future tax benefit to be derived from tax credits and loss carry forwards. Current income tax expense or benefit represents the amount of income taxes expected to be payable or refundable for the current year. A valuation allowance is established when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive Loss Comprehensive loss includes unrealized gains and losses on debt and equity securities classified as available-for-sale and included as a component of shareholders’ equity.
Earnings Per Share, Policy [Policy Text Block]	Net Loss per Share Basic net loss per share has been computed by dividing net loss by the weighted average number of common shares outstanding.
