TomTom XXL 550-T Question

[Bionic]

Hey guys,

I have been using an old Garmin for years and years - got a new TomTom from Santa Claus, but have an issue:

My car is very, very old and there is a problem with the fuses/cigarette lighter/everything in the car.

My basic question is this: What is the best external/usb battery I can buy so I can get the maximum hours out of my GPS? I'm looking for something so that I can go on road trips without worry. I won't be going any longer than 5 hours each way.

I've been searching online all day, and haven't really come up with anything concrete.

Thank you so much for your help -
Michael

You might want to have a look at this device - although hard wiring a 12V cable + cig outlet + fuse (available as an assembly from Radio Shack) might be easier and won't need charging all the time...

The Radio Shack part gives you a hardwired input and 3 cig lighter sockets to power whatever:
