Long car trips - have kids!!!!

Car power inverter, that's what I use, and it is nice because you can use it with anything. Make sure you get a big enough one. i would look online for a good deal.

O had one, and started using it for everything like a slushie machine in my Jeep and stuff, and found the one I got wasn't powerful engouh. It was one of those deals that plugs into the lighter power plug. Anyway, i got one that I wired right into the car battery and gives me 2 outlets.

Now there is no problem running my popcorn machine and the plasma tv at the same time. Also look into MS Streets & Trip '06 with the USB GPS. THAT is a sweet thing for $80 online.
