Iphone 5s charging using 5V/2.1A powerbank
I Bought a power bank whose output is 5V/2.1A . Is there any problem of charging my iphone 5s using this powerbank?
iPhone 5s, iOS 9.3
as long as the volts are 5volts it can't hurt amps is just an indication of how much amp can be drawn from it it could be 100 and work fine.
