And, you'll never have to remove the Power Pack from your iPhone. Simply use the cable supplied with your Power Pack to both charge your iPhone and Power Pack and synchronize your phone. Charge and synch simultaneously!nnnnAvailable in Black and White.nnnnThe Power Pack makes a fabulous Holiday Gift! And, don't forget to treat yourself.
