I just wanted to add something to this thread. I bought this and like others I discovered it would not charge the phone with the GPS and other stuff on. I emailed the company and told them mine wasn't charging. They said they would send a new one out. It seemed to take forever, it arrived today and the new one appears to charge. I have the GPS, Bluetooth, 4g on and have it hooked to a 1 amp charger. Its charging anywhere from 70-200 mA. I admit that's not a large charge but at least the battery won't go dead on the road. I suspected they modified it I'll pop it apart tomorrow and take a peek.
