Hello I have a question the device I'm powering up needs 12v 2amps to run it. Well it said that but i measure it at 1.6amps close to 1.7amps. and i have also a arduino on it going from the 12v down to 5v with no problem. Right now currently it's on a Power adapter but i need to make it portable. So…

12V 2Amps on 18650 batteries.
