watt = amps *volt
this mean
amps = watt / volt
the ac charger is 5Watt and 5volt
so 1 amp
but the phone also charge at usb which in some cases is 5volt 0.5amp == 2.5watt
are you looking for how further down then 0.5 amps you can go ?
the lower the amps the slower it charges
The minimum is 0.5 amps. It will not charge at lower currents. The maximum it will draw is 1 amp, even if you connect it to a USB adapter that can supply more than 1 amp.
