Cash and cash equivalents primarily consist of cash and deposits with financial institutions which are unrestricted as to withdrawal and use. Cash equivalents consist of highly liquid investments that are readily convertible to cash generally with original maturities of three months or less when purchased.

The Company had bank acceptance notes outstanding with the bank and is required to keep certain amounts on deposit that are subject to withdrawal restrictions. Those notes are generally short term in nature due to their short maturity period of six to nine months; thus, restricted cash is classified as a current asset.

In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts presented in the statement of cash flows. The Company adopted the new standard effective January 1, 2018, using the retrospective transition method.

As of June 30, 2026, and December 31, 2025, restricted cash was $337,426 and $251,932, respectively.

Accounts receivables are recognized and carried at the original invoiced amount less an estimated allowance for uncollectible accounts. The Company usually determines the adequacy of reserves for doubtful accounts based on individual account analysis and historical collection trends. The Company establishes a provision for doubtful receivables when there is objective evidence that the Company may not be able to collect amounts due. The allowance is based on management’s best estimates of specific losses on individual exposures, as well as a provision on historical trends of collections. Based on management of customers’ credit and ongoing relationship, management makes conclusions whether any balances outstanding at the end of the period will be deemed uncollectible on an individual basis and on aging analysis basis. The provision is recorded against accounts receivables balances, with a corresponding charge recorded in the consolidated statements of income and comprehensive income. Delinquent account balances are written off against the allowance for doubtful accounts after management has determined that the likelihood of collection is not probable.

Inventories are stated at the lower of cost or net realizable value. Cost is principally determined using the weighted-average method. The Company records adjustments to inventory for excess quantities, obsolescence or impairment when appropriate to reflect inventory at net realizable value. These adjustments are based upon a combination of factors including current sales volume, market conditions, lower cost or market analysis and the expected realizable value of the inventory.

Advances to suppliers refer to advances for purchase of materials or services, which are applied against accounts payable when the materials or services are received.

The Company reviews a supplier’s credit history and background information before advancing a payment. If the financial condition of its suppliers were to deteriorate, resulting in an impairment of their ability to deliver goods or provide services, the Company would write off such an amount in the period when it is considered impaired. As of June 30, 2026 and December 31, 2025, the Company had no write-offs for advances to suppliers.

Advances from customers refer to advances received from customers, which are applied against accounts receivable when products are sold.

Property, plant, and equipment are recorded at cost less accumulated depreciation. Depreciation commences upon placing the asset in use and is recognized on a straight-line basis over the estimated useful lives of the assets with 5% of residual value, as follows:

Expenditures for maintenance and repairs, which do not materially extend the useful lives of the assets, are charged to expense as incurred. Expenditures for major renewals and betterments which substantially extend the useful life of assets are capitalized. The cost and related accumulated depreciation of assets retired or sold are removed from the respective accounts, and any gain or loss is recognized in the consolidated statements of income and other comprehensive income in other income or expenses.

Effective January 1, 2018, the Company adopted the new lease accounting standard using a modified retrospective transition method which allowed the Company not to recast comparative periods presented in its consolidated financial statements. In addition, the Company elected the package of practical expedients, which allowed the Company to not reassess whether any existing contracts contain a lease, to not reassess historical lease classification as operating or finance leases, and to not reassess initial direct costs. The Company has not elected the practical expedient to use hindsight to determine the lease term for its leases at transition. The Company combines the lease and non-lease components in determining the ROU assets and related lease obligation. Adoption of this standard resulted in the recording of operating lease ROU assets and corresponding operating lease liabilities as disclosed in financial statements. ROU assets and related lease obligations are recognized at commencement date based on the present value of remaining lease payments over the lease term. 

The Company’s management reviews the carrying values of long-lived assets whenever events and circumstances, such as a significant decline in the asset’s market value, obsolescence or physical damage affecting the asset, significant adverse changes in the assets use, deterioration in the expected level of the assets performance, cash flows for maintaining the asset are higher than forecast, indicate that the net book value of an asset may not be recovered through expected future cash flows from its use and eventual disposition. If the estimated cash flows from the use of the asset and its eventual disposition are below the asset’s carrying value, then the asset is deemed to be impaired and written down to its fair value.

There was no impairment charge recognized for long-lived assets for the periods ended June 30, 2026 and December 31, 2025.

Fair Value Measurements and Disclosures requires disclosure of the fair value of financial instruments held by the Company. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

ASC 820-10 describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations for those future amounts. The cost approach is based on the amount that would currently be required to replace an asset. 

For the Company’s financial instruments, including cash and cash equivalents, restricted cash, accounts receivable, other receivables, accounts payable, other current liabilities, and bank loans, the carrying amounts approximate their fair values due to their short maturities as of June 30, 2026 and December 31, 2025.

Sales revenue represents the invoiced value of goods, net of VAT. All of the Company’s products that are sold in the PRC are subject to a VAT on the gross sales price.  The Company is subject to a VAT rate of 17% before May 1, 2018, 16% on and after May 1, 2018, and a new VAT rate of 13% effective on April 1, 2019. The VAT may be offset by VAT paid by the Company on raw materials and other materials included in the cost of producing or acquiring its finished products.

The Company generates its revenues mainly from sales of electrical products, such as electrical converters and inverters, to third-party customers, who are mainly distributors and retailers. The Company follows Financial Accounting Standards Board (FASB) ASC 606 and accounting standards updates (“ASU”) 2014-09 for revenue recognition. On January 1, 2018, the Company has early adopted ASU 2014-09, which is a comprehensive new revenue recognition model that requires revenue to be recognized in a manner to depict the transfer of goods or services to a customer at an amount that reflects the consideration expected to be received in exchange for those goods or services. The Company considers revenue realized or realizable and earned when all the five following criteria are met: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation.

The Company considers customer purchase orders, which in some cases are governed by master sales agreements, to be the contracts with a customer. As part of its consideration of the contract, the Company evaluates certain factors including the customer’s ability to pay (or credit risk). For each contract, the Company considers the promise to transfer products, each of which is distinct, to be the identified performance obligations. In the principal versus agent consideration, since no another party is involved in transactions, the Company is a principal.

In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. The Company analyzed historical refund claims for defective products, and since no warranty, discount or return policy are documented in the sales agreements, the Company concluded that they have been immaterial.

Revenues are reported net of all value added taxes. As the Company’s standard payment terms are less than one year, the Company has elected the practical expedient under ASC 606-10-32-18 to not assess whether a contract has a significant financing component. The Company allocates the transaction price to each distinct product based on their relative standalone selling price.

Revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied at a point in time), which typically occurs at delivery. For international sales, the Company sells its products primarily under the free onboard (“FOB”) shipping point term. For sales under the FOB shipping point term, the Company recognizes revenues when products are delivered from Company to the designated shipping point. Prices are determined based on negotiations with the Company’s customers and are not subject to adjustment. 

Rental income is from subleasing part of the leased assets under operating leases, and it is recognized in the statements of comprehensive income on a straight-line basis over the term of the lease.

Government grants are compensation for expenses already incurred or for the purpose of giving immediate financial support to the Company. The government evaluates the Company’s eligibility for the grants on a consistent basis, and then makes the payment. Therefore, there are no restrictions on the grants.  

Government grants are recognized when received and all the conditions for their receipt have been met. The grants received were $49,468 and $87,823 for the six months ended June 30, 2026 and 2025, respectively, which were included in other income on Income Statement.  

Research and development activities are directed toward the development of new products as well as improvements in existing processes. These costs, which primarily include salaries, contract services and supplies, are expensed as incurred.

Shipping and handling costs are expensed when incurred and are included in selling and marketing expenses. Shipping and handling costs were $123,272 and $70,765 for the six months ended June 30, 2026 and 2025, respectively.

Advertising costs are expensed as incurred in accordance with ASC 720-35, “Selling and Marketing Expenses-Advertising Costs”. Advertising costs were $83,605 and $28,714 for the six months ended June 30, 2026 and 2025, respectively.

The Company accounts for income taxes using the asset and liability method whereby it calculates deferred tax assets or liabilities for temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements, net operating loss carry forwards and credits by applying enacted tax rates applicable to the years in which those temporary differences are expected to be reversed or settled. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws of the relevant taxing authorities. The components of the deferred tax assets and liabilities are individually classified as non-current amounts.

The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process whereby (1) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

To the extent applicable, the Company records interest and penalties as other expense. All the tax returns of the Company’s PRC subsidiaries remain subject to examination by PRC tax authorities for five years from the date of filing. The fiscal year for tax purposes in PRC is December 31.

The Company and its subsidiaries are not subject to U.S. tax laws and local state tax laws. The Company’s income and that of its related entities must be computed in accordance with Chinese and foreign tax laws, as applicable, and all of which may be changed in a manner that could adversely affect the amount of distributions to shareholders. There can be no assurance that the Income Tax Laws of PRC will not be changed in a manner that adversely affects shareholders. Any such change could increase the amount of tax payable by the Company, reducing the amount available to pay dividends to the holders of the Company’s ordinary shares.

Earnings (loss) per share is calculated in accordance with ASC 260 Earnings per Share. Basic earnings (loss) per share is computed by dividing the net income (loss) attributable to shareholders of the Company by the weighted average number of ordinary shares outstanding during the year. Diluted earnings per share are computed in accordance with the treasury stock method and based on the weighted average number of ordinary shares and dilutive ordinary share equivalents. Dilutive ordinary share equivalents are excluded from the computation of diluted earnings per share if their effects would be anti-dilutive. There were no dilutive ordinary share equivalents outstanding during the six months ended June 30, 2026 and 2025.

The Company did not use the two-class method to compute net income per ordinary share, because it did not have other issued securities other than ordinary shares. Class A and Class B shares are both ordinary shares, and per Article 6 in Memorandum and Articles of Association (amended and restated), they have the same rights, preferences, privileges, and restrictions, except for voting and conversion rights. 

Comprehensive income/(loss) is defined as the changes in shareholders’ equity during a period arising from transactions and other events and circumstances excluding transactions resulting from investments by shareholders and distributions to shareholders. Comprehensive income or loss is reported in the consolidated statements of comprehensive income/(loss). Accumulated other comprehensive income/(loss), as presented on the accompanying consolidated balance sheets, consists of accumulated foreign currency translation adjustments.

Exchange Rate Risks

The Company operates in PRC, which may give rise to significant foreign currency risks mainly from fluctuations and the degree of volatility of foreign exchange rates between the USD and the RMB.

Currency Convertibility Risks

Substantially all the Company’s operating activities are transacted in RMB, which is not freely convertible into foreign currencies. All foreign exchange transactions take place either through the People’s Bank of China or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the People’s Bank of China. Approval of foreign currency payments by the People’s Bank of China or other regulatory institutions requires submitting a payment application form together with other information such as suppliers’ invoices, shipping documents and signed contracts.

Concentration of Credit Risks

Financial instruments that potentially subject the Company to concentration of credit risks consist primarily of cash and cash equivalents, restricted cash, notes receivable. The Company places its cash and cash equivalents, restricted cash, and note receivable in good credit quality financial institutions in Hong Kong and PRC. Concentration of credit risks with respect to accounts receivables is linked to the concentration of revenue. To manage credit risk, the Company performs ongoing credit evaluations of customers’ financial condition.

Interest Rate Risks

The Company is subject to interest rate risk. The Company has bank interest bearing loans charged at variable interest rates. And although some bank interest bearing loans are charged at fixed interest rates within the reporting period, the Company is still subject to the risk of adverse changes in the interest rates charged by the banks when these loans are refinanced.

Risks and Uncertainties

The operations of the Company are located in the PRC. Accordingly, the Company’s business, financial condition, and results of operations may be influenced by political, economic, and legal environments in the PRC, as well as by the general state of the PRC economy. The Company’s results may be adversely affected by changes in the political, regulatory and social conditions in the PRC. Although the Company has not experienced losses from these situations and believes that it is following existing laws and regulations including its organization and structure disclosed in Note1, this may not be indicative of future results.

Liquidity Risks

Our primary sources of liquidity consist of existing cash balances, cash flows from our operating activities and availability under our revolving credit facility. Our ability to generate sufficient cash flows from our operating activities is primarily dependent on our sales of converters and power generating products to our customers at margins sufficient to cover fixed and variable expenses.

As of June 30, 2026, and December 31, 2025, we had cash and cash equivalents of $2,830,218 and $436,788, respectively. We believe that our current cash, cash to be generated from our operations and access to loans from our related parties will be sufficient to meet our working capital needs for at least the next twelve months. Although we do not have any amounts committed to be provided by our related parties, due to their relatively small amounts, we do not believe our working capital needs will be negatively impacted without such funds provided by related parties.   We are also not dependent upon additional external financing   to meet our liquidity needs for the next twelve months. However, we plan to expand our business to implement our growth strategies in our existing market and strengthen our position in the marketplace. To do so, we will need more capital through equity financing to increase our production and meet market demands.
