I want to add an USB port on my APC UPB50 battery so i can charge my phone and laptop. Answered
I want to add an USB port on my APC UPB50 battery so I can charge my phone and laptop. Since the battery is seal, I can't open it up. I plan to make an adapter from the power out plug.
When I check the power from the outside and inside walls of the plug i get 19v.
From the outside wall and the pin inside, i get 5v, can i use the 5v to charge my phone.
Can I just hook up a wall charger to the power out plug and charge my phone?
I'm new to this kind of tinkering and it's a step up from what I normally make. I need guidance.
