We have a new Pantech Breeze II cell phone that is charged via USB cord. The provided USB cord attaches to 110 AC to DC adapter. I wonder if thesame USB cable that connects the phone to the AC->DC adapter can be used in the USB port provided in the 2010 Ford Edge. I worry the voltage out of the USB port may not be controlled. Maybe a better solution is to buy a regulated adapter that can be plugged into the cigar lighter.
