oh did this mod to one of my el cheapo twin pack PRS radio's the radio's are great but chew the AAA batteries so decided to modify one to run on USB as it works out to the same voltage/amps, added a 3 way cigarette adapter to the top of the dash and now i can just plug the PRS into a spare USB charger and run it off that when in the cab and use the other unmodified one when out of the truck.
