I am the proud new owner of a PS Pass thru and it works awesome plugged into my 2 amp AC to USB wall unit. But I really want to use this PT in the car. Has anyone found a cigarette lighter USB adapter that is rated at 1 1/2 or 2 amps? The units I have are all rated at 1/2 amp or 750 ma. They won't even start the PT up! I know someone has to have tackled this issue.
