Hi guys, Scoured the internet but came up with nothing. Im looking for a portable charger with built in battery that has both a 30-pin connector built in and wall-plug. This way I won't forget either a usb cable or be forced to plug a portable charger into a computer when I'm not near one. Was able to find a few charger with either the wall plug built in or 30 pin connector and not both. Any help?
