I've bought a USB wall charger to power my Raspberry Pi. I chose the 3A one so that I can connect some more power hungly devices like hard drives to the Pi's USB ports.
I can connect 2 cables to the charger I bought. I have two questions about it.
- the charger that came with my Android is 1,2 A I think. Is it potentially harmfull to my phone if I charge it with my new charger since it is 3 A?
- will I have a maximum of 3 A in total on the ports (so 2 * 1.5 for example), of will I have 3 A on each?
