PROSPECTUS
SUPPLEMENT
(To
Prospectus dated September 25, 2026)
POLAR
POWER, INC.
Up
to 8,653,774 Shares of Common Stock
This
prospectus relates to the offer and resale from time to time by the Selling Stockholders named herein (the “Selling Stockholders”)
of up to 8,653,774 shares (the “Shares”) of our common stock, par value $0.0001 per share (“Common Stock”). Certain
of the Selling Stockholders will be selling Shares to be issued to them pursuant to their conversion of certain convertible notes or
preferred stock or their exercise of certain warrants. The exact number of shares of our Common Stock that may be issued to Selling Shareholders
pursuant to the convertible notes and preferred stock is not currently determinable because the applicable conversion prices are variable
and are determined by reference to the market price of our Common Stock at the time of conversion. The number of shares set forth in
this prospectus is an estimate determined by us and does not necessarily reflect the number of shares that will actually be issued or
resold. See “Risk Factors.”
We
are not selling any securities under this prospectus and will not receive any proceeds from the sale of shares of Common Stock by the
Selling Stockholders. However, certain of the Selling Stockholders may acquire the Shares they are selling in this offering through their
exercise of warrants, and we would receive the proceeds of any exercise of the warrants to the extent they are exercised for cash. See
“Use of Proceeds.”
The
Selling Stockholders may offer and sell the shares of Common Stock from time to time at fixed prices, at prevailing market prices at
the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated
prices. The Selling Stockholders may sell shares through agents, broker-dealers, or underwriters, or directly to purchasers. For additional
information on the methods of sale that may be used by the Selling Stockholders, see “Plan of Distribution.”
Our
Common Stock is listed on the Nasdaq Capital Market under the symbol “POLA.” On October 27, 2026, the last reported
sale price of our Common Stock on the Nasdaq Capital Market was $0.6429 per share.
We
are a “smaller reporting company” as defined in Rule 12b-2 of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”), and have elected to take advantage of certain of the scaled disclosures available to smaller reporting companies. See “Prospectus
Summary—Implications of Being a Smaller Reporting Company.”
Investing
in our securities involves a high degree of risk. See “Risk Factors” beginning on page 7 of this prospectus for a discussion
of information that should be considered in connection with an investment in our securities.
Neither
the Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of these
securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.
The
date of this prospectus is October 28, 2026.
Selling
Stockholders
The
following information amends and supplements the information that appears under the heading “Selling Stockholders” beginning
on page 11 of the prospectus. Capitalized terms used herein but not defined have the meanings ascribed to such terms in the prospectus.
Mayers
Ventures LLC, a Selling Stockholder included in the prospectus, transferred the securities it holds in the Company to Mandragula Ltd.
The table that appears under the heading “Selling Stockholders” in the prospectus is being amended and supplemented to (i)
remove Mayers Ventures LLC as a Selling Stockholder and (ii) add Mandragula Ltd. as a Selling Stockholder. This prospectus supplement
does not impact any other Selling Stockholder set forth in the table appearing under the heading “Selling Stockholders” in
the prospectus.
The

outstanding as of September 10, 2026, and assumes the exercise or conversion of any securities exercisable or convertible into Common
Stock owned by such Selling Stockholder but not the exercise or conversion of such securities owned by any other Selling Stockholder.

shares of Common Stock issuable upon the exercise of Warrants. The exact number of shares that may be issued to Mandragula Ltd. pursuant
to the Note is not currently determinable because the applicable conversion prices are variable and are determined by reference to the

the Note. Number of shares owned prior to offering reflects a limit on convertibility and exercise equal to 9.99% of total shares outstanding.
The shares as referenced herein are directly held by Mandragula Ltd., and may be deemed to be indirectly beneficially owned by Gur Aryeh
Segal, who may be deemed to have sole voting and dispositive power with respect to the shares held by Mandragula Ltd. The address of
Mandragula Ltd. is 8 Gavish Street, Bet Sarel, Netanya, Israel.
