Hi, i have a PSU that can deliver 5A at +5V. I would like to use it to charge my phone. I was wondering though, whether its high current capability would affect my phone (would the 5A be flowing through my phone, or is it somehow limited inside the phone?). I'm not sure whether to add a current limiting circuit (transistor, or even a simple series resistor). Could someone tell me whether i should add a current limiting circuit in series with the phone to limit it at a safe current (1A is what im looking for) thanks.
