Re: E-Power Inc.

Ladies and Gentlemen:

We have acted as U.S. securities counsel to E-Power Inc., a company established under the laws of the Cayman Islands (the “Company”), in connection with (i) the registered direct offering (the “Offering”) by the Company of 229,097 Class A ordinary shares, par value US$0.0025 per share (the “Shares”), and 292,393 pre-funded warrants (the “Pre-Funded Warrants”) to purchase Class A ordinary shares of the Company (the “Pre-Funded Warrant Shares”) pursuant to that certain Securities Purchase Agreement, dated September 29, 2026 (the “Securities Purchase Agreement”), by and between the Company and the purchaser identified on the signature page thereto, and (ii) the issuance by the Company of warrants to the placement agent or its designees to purchase an aggregate of 26,074 Class A ordinary shares (the “Placement Agent Warrants” and the shares issuable upon exercise thereof, the “Placement Agent Warrant Shares”) pursuant to the Placement Agency Agreement, dated September 29, 2026 (the “Placement Agency Agreement”), by and between the Company and FT Global Capital, Inc. relating to the Offering.

The Company registered the offering and sale of the Shares, the Pre-Funded Warrants, and the Pre-Funded Warrant Shares by means of a prospectus supplement filed with the U.S. Securities and Exchange Commission (the “SEC”) on September 30, 2026 (the “Prospectus Supplement”), related to the registration statement on Form F-3 (File No. 333-297688), including the base prospectus (the “Base Prospectus”) (the “Registration Statement”), which was initially filed with the SEC on July 24, 2026 and declared effective on July 30, 2026. The Placement Agent Warrants and the Placement Agent Warrant Shares are not being registered under the Securities Act of 1933, as amended (the “Securities Act”), are not being offered pursuant to the Prospectus Supplement and the accompanying Base Prospectus and are being offered pursuant to the exemption provided in Section 4(a)(2) under the Securities Act and/or Rule 506(b) promulgated thereunder. All capitalized terms used herein and not expressly defined herein have the meanings specified in the Placement Agency Agreement and the Securities Purchase Agreement. This opinion is being furnished to you in connection with the Registration Statement, the Base Prospectus and the Prospectus Supplement.

In rendering the opinions expressed below, we have examined physical or electronic copies of:

For purposes of this opinion, we have assumed (i) the validity and accuracy of the documents and corporate records that we have examined, (ii) the genuineness of all signatures, (iii) the legal capacity of all natural persons, (iv) the authenticity of all documents submitted to us as originals, (v) the conformity to original documents of all documents submitted to us as certified or photostatic copies, and (vi) the authenticity of the originals of such documents. As to any facts material to the opinion expressed herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Company and have assumed that such statements and representations are true, correct and complete without regard to any qualification as to knowledge or belief. Our opinion is conditioned upon, among other things, the initial and continuing truth, accuracy, and completeness of the items described above on which we are relying.

You are advised that we are members of the Bar of the State of New York. We express no opinion concerning any matters respecting or affected by any laws other than laws that a lawyer in New York exercising customary professional diligence would reasonably recognize as being directly applicable to the transactions contemplated by the Placement Agency Agreement, the Securities Purchase Agreement, the Pre-Funded Warrants, and the Placement Agent Warrants (collectively, the “Transaction Documents”). Because the agreements governing the Pre-Funded Warrants and the Placement Agent Warrants contain a provision stating that they are to be governed by the laws of the State of New York, we are rendering this opinion as to New York law. We advise you that we are licensed to practice law only in the State of New York. We express no opinion as to any county, municipal, city, town or village ordinance, rule, regulation or administrative decision. With respect to the Shares, the Pre-Funded Warrant Shares and the Placement Agent Warrant Shares being duly and validly issued, fully paid and non-assessable, we have relied on the opinion of Ogier (Cayman) LLP filed as Exhibit 5.1 to the Company’s Report of Foreign Private Issuer on Form 6-K filed on October 5, 2026.

Based upon and subject to the foregoing, we are of the opinion that each of the Pre-Funded Warrants and the Placement Agent Warrants, if and when issued, delivered and paid for as contemplated by the terms of the Transaction Documents, will be valid and binding obligations of the Company enforceable against the Company in accordance with their respective terms, except: (a) as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally and by general equitable principles (regardless of whether enforceability is considered in a proceeding in equity or at law); (b) as enforceability of any indemnification or contribution provision may be limited under the federal and state securities laws; (c) that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to the equitable defenses and to the discretion of the court before which any proceeding therefor may be brought; (d) the effect of course of dealing, course of performance, oral agreements or the like that would modify the terms of an agreement or the respective rights or obligations of the parties under an agreement; and (e) we have assumed the Exercise Prices (as defined in the Pre-Funded Warrants and the Placement Agent Warrants, respectively) will not be adjusted to an amount below the par value per Class A ordinary share.

Notwithstanding anything in this letter which might be construed to the contrary, our opinion herein is expressed solely with respect to the laws of the State of New York. Our opinion is based on these laws as in effect on the date hereof. Our opinion represents only our interpretation of the law and has no binding, legal effect on any court. It is possible that one or more courts may sustain such contrary positions. Our opinion is expressed as of the date hereof, and we are under no obligation to supplement or revise this opinion to reflect any changes, including changes which have retroactive effect (i) in applicable law or (ii) in any fact, information, document, corporate record, covenant, statement, representation, or assumption stated herein that becomes untrue, incorrect or incomplete.

This letter is furnished to you for use in connection with the Offering and is not to be used, circulated, quoted, or otherwise referred to for any other purpose without our express written permission. We hereby consent to the filing of this opinion as an exhibit to a Report of Foreign Private Issuer on Form 6-K that is incorporated by reference in the Registration Statement and to the use of our name in the Registration Statement, the Base Prospectus and the Prospectus Supplement wherever it appears. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the SEC thereunder.
