I can only say: BUY - BUY - BUY !! Try also to my new Galaxy Tab 10.1 to load the adapter directly to the PC. The adapter is plugged into the USB port of a desktop PC and on the other hand, the original cable from Tab. Works excellent and invites in the same time as on the original power supply. The same I've tried in the car (Audi A6 Variant) ..... works just. Hab equal ordered me a second adapter to not always between car and home now and take her ... at the price that's easy indoors. If you put between this adapter it is completely no matter what device is being charged. Absolute buy recommendation!
