The Samsung adapter I have here is 0.7amps, slow as treacle compared to the one which came with my N5.
But the cable cannot be rated for amps, that doesn't make sense.
Get a PortaPow cable from Amazon and it will charge at full speed. However, you also need a minimum of a 2A charger for it to charge in a decent time.
But the cable is not rated for amps, please stop saying that.
Why are you upset?
Because he has a low ampage cable, so low that it only works when charging downhill.
Because people are spouting incorrect information. It annoys me when they do that.
