I have a Zire 72 palm PDA and I need a car power supply adapter for it. One that is a true power supply and not a trickle charger. I have the trickle charger that plugs into the USB port on the bottom of the unit. But the problem with that is that if I leave my Zire on while driving around in the car all day the battery in the Zire slowly loses its charge.
Is there something out there beside the trickle charger?
