I know this may sound retarded to some of you, but are there any risks in using a USB wall plug with 5V/0.85A to charge a 5V/0.5A device? what about a 5.1V/2.3?
I'm afraid this might damage the battery in the long run, but what's the point of the USB if that can happen?
read the specifications written on the battery, they're written there for a reason
It's perfectly safe. You could use something with a 5v 100a output and the device will only draw the power it needs. If the voltage was way off that would be a different story.
