Dock and USB cable for charging and data exchange work very well on the PC! The Netztadapter but fails completely, either with or without dock no charging function for the S3! SAMSUNG seems to prefer his own power supplies here. Here I sit, and would have liked that this would pdashop previously tested properly. Unfortunately not. On my complaint he refers to his right to force me to pay the return postage. This obliges me to dispose of the part and an original SAMSUNG to buy, but not in pdashop.
