**Changes in Registrant's Certifying Accountant**

On July 25, 2025, the audit committee of the board of the directors (the "Board") of U Power Limited, a company incorporated under the laws of the Cayman Islands (the "Company"), recommended, and the Board approved, the change of the Company's independent auditor to HHL LLP ("HHL"), in place of Onestop Assurance PAC ("Onestop"). The termination of the engagement with Onestop became effective as of July 24, 2025, and the engagement of HHL as the independent auditor of the Company became effective as of July 24, 2025.

Onestop's report on the Company's financial statements for the years ended December 31, 2024 and 2023 did not contain an adverse opinion or disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit scope, or accounting principles. Furthermore, during the Company's two most recent fiscal years and through July 24, 2025, there were no disagreements with Onestop on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to Onestop's satisfaction, would have caused Onestop to make reference to the subject matter of the disagreement in connection with its reports on the Company's financial statements for such periods. During the Company's two most recent fiscal years and through July 24, 2025, there were no "reportable events," as that term is described in Item 16F(a)(1)(v) of Form 20-F, other than the material weaknesses identified by management under the Company's annual report on [Form 20-F](https://www.sec.gov/Archives/edgar/data/1939780/000121390025044284/ea0239478-20f_upower.htm) (File No. 001-41679), which was filed with the U.S. Securities and Exchange Commission on May 15, 2025.

The Company has provided Onestop with a copy of the above disclosure and requested that Onestop furnish a letter addressed to the Commission stating whether or not it agrees with the above statements. A copy of Onestop's letter is filed herewith as Exhibit 16.1.

During the two most recent fiscal years and any subsequent interim periods prior to the engagement of HHL, neither the Company, nor anyone on behalf of the Company, has consulted HHL regarding either the application of accounting principles to a specified transaction, whether completed or proposed, or the type of audit opinion that might be rendered on the Company's consolidated financial statements. Neither a written report was provided to the Company nor was any oral advice provided that HHL concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing, or financial reporting issue. Additionally, neither the Company, nor anyone on behalf of it, has consulted HHL regarding any matter that was the subject of a "disagreement" as defined in Item 16F(a)(1)(iv) of Form 20-F and related instructions to Item 16F of Form 20-F, or any "reportable events" as described in Item 16F(a)(1)(v) of Form 20-F.

**SIGNATURE**

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.
