This is a 5V/2A USB wall adapter. The input is AC 100-240V.
Note: It doesn't come with a USB cable.
Plenty of power

This is a good USB power adapter with plenty of power at a reasonable price. The unit I received does not match the picture shown here, what I received looks a bit nicer, more rectangular, with a smooth finish and with the AC prongs on one of the flat sides. It's still a little bulky and it would be nicer if the prongs folded into the unit for easier storage and transport.
