Greetings, I received this charger yesterday and tested it today on a fully discharged iPhone 3GS. It charged up to 82% of the iPhone's battery capacity and ran out of juice. Bad charger. Walk well, Jim Keener ( J J ) _________________ jj at ridgetrailhiker.com http://postholer.com/jj http://ridgetrailhiker.com http://olderhealthier.com
