Arrived quickly, well packed and high quality USB cable. I'm impressed!
I just tested the adapter and IT DOES NOT WORK. No POWER goes to camera. Tried 3 different 2Amp plugs. Nothing. Unit is dead on arrival. I'm waiting for response from seller. I asked for a new unit. Let's see.
Works perfectly, BUT you NEED to use a usb charger with more voltage output than your camera's battery. (For example: EOS 600D battery is 7.1V. This won't work in a usb charger with 5V output. It works fine in a usb charger with 12V output.)
