Power Adapters

I am wondering if anybody here is using any sort of power adapters with their GPS and other electronic devices? I have a Uniden Home Patrol HP-1 scanner or order. I only have one 12 volt 10 amp power outlet up front. I am considering one of the following devices:

-XTG Technology 5-in-1 Auto Charger. 4-Port USB Car Charger and 1 12V DC Cigarette Socket Model Number: XTG-4USB12V

-Tom Tom High Speed Multi-Charger

What I am planning on doing is using the 12 volt port of either device for the Uniden Home Patrol HP-1 and one of the USB ports for the Garmin Nuvi 350. Does anybody here have any thoughts on which, if either, would be better than the other for that appplication? I guess I don't know what the power requirements of the Garmin Nuvi 350 are at 5 volts. I would suspect that it is around 1 amp at 5 volts.

Specs

Power Input: 12/24 VDC
Usage: 13W max @ 13.8 VDC

I am not sure what the charge input is anymore - The 350 was my first one and I belive the wall charger was rated at 5V @ 2A.

Anyway the specs are in the manual - here's the link.

looking at the XTG

Looking at the specs for the XTG I see:
Input: 12 ~ 24VDC. Output 5.0 ~ 5.5V. Output Current: 2000mA (total for the 5 charge ports).

The typical USB output current is 1/2 an amp, so if all 4 were in use, that's 2,000 mA which leaves none for the cigarette lighter socket. My feeling is this will not accomplish what you want as the output power is woefully inadequate for more than 1 or 2 devices. You'd better check the current draw on your devices before spending the money for something you would end up throwing away.

As I was saying

I split the 12 volts in two using this cheapie.

Then a USB charger would work on one and GPS on the other. I use it for my 2 GPS units.

I know it's not what you're looking for,

but I've installed one of these things at home to charge GPS, cell phones and iTouches via usb port or by wall wart. It works very good!
