I will be returning this to the Apple Store tonight. Nice design, but cheaply engineered. Disappointed. Might be good if you dont ever plan to unplug the wire from the base, if you do you"ll have to be very careful not to bend the fragile metal parts in the base receptor.
I have now tried two of these and they both do the same thing. One device, plugged into one of the USB ports works great. It charges my iPhone 4S more quickly than any other car charger I have used. When you plug a second device in, however, neither one gets power and you have to unplug both devices, unplug the charger and then plug it back in to get it to work again. My intent was to power my Elevate 4G Hotspot and my iPhone, but it won't do it. The vehicle is a full size Range Rover. I even took the truck to the dealer to be sure that it wasn't the problem, but they said the RR was fine. The problem occured on 3 of the vehicle's outlets.
Looking for another solution
