Ladies and Gentlemen:

We have acted as counsel to Blink Charging Co., a Nevada corporation (the “Company” or the “Registrant”), in connection with the preparation and filing by the Registrant of a shelf registration statement on Form S-3 (the “Registration Statement”) with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the offering from time to time, pursuant to Rule 415 under the Securities Act, of (i) shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), (ii) shares of the Company’s preferred stock, par value $0.001 per share (the “Preferred Stock”), (iii) debt securities of the Company (the “Debt Securities”), which may be senior or subordinated, (iv) warrants to purchase Common Stock, Preferred Stock, or Debt Securities (the “Warrants”), (v) rights to purchase Common Stock, Preferred Stock or Debt Securities (the “Rights”), and (vi) units consisting of one or more shares of Common Stock or Preferred Stock, Debt Securities, Warrants, Rights or any combination of those securities (the “Units” and, together with the Common Stock, the Preferred Stock, the Debt Securities, the Warrants and the Rights, the “Securities”). The offering of the Securities will be as set forth in the prospectus forming a part of the Registration Statement (the “Prospectus”), as supplemented by one or more supplements to the Prospectus (each, a “Prospectus Supplement”). The aggregate offering price of the Securities being registered will not exceed $100,000,000.
