I have read a long time ago the Pi went up to 5.25v for its power supply but at the time 5.3v didn't commonly exist. Would I have any problems with using one that gives a little to much voltage. It will be for a Pi 2.
I ask because in a unrelated thing I read before when they first started coming out on a Android phone forum was that you could charge older phones with them but the extra voltage would over time lower the batteries life. I know the Pi doesn't have a battery but would other components have any problem.
I let someone borrow one of my Pi's to try it out and they are using my good 5.25v 2 amp. So I'm seeing what I have laying around until I can buy a 5.25v 3 amp I saw online.
