I need advice on how to power a Canon R5 with a power bank in remote locations without electrical power. Often in need 5 plus hours of continuous power. I have a Canon dummy battery and hope to find a power bank that will provide enough safe power that I can pair with it without damaging the camera. 5 volt 2 amp power banks will not power the camera. I believe I will need a 9volt 3 amp minimum battery but wondering if the dummy battery or internal circuitry can regulate a 12 volt 5 amp battery input.
