powering laptop in a car

[MrSlacker]

my parents decided to take a trip to Florida to see our relatives. we will be driving there so its gonna be 24+ hours drive. i dont want to die from boredom so we will have 2 laptops with us to watch movies and stuff like that. so my question is, what is the best car surge that can power 2 laptops. i found these http://www.apc.com/resource/include/..._sku=PNOTEAC75

get any cheap power inverter.

i personally use a 300W one from target when i was doing stuff with my laptop int eh car. the battery int eh lappy only lasted long enough to get the car running again when i had to shutdown to reprogram....

anyways, any 300W inverter, prefferably with 2 ac plugs, then just plug your lapptop's psu/charger thingy into that.

if you go to radioshack, and pay too much for not enough, i will hurt you.

i will probly get this one http://www.apc.com/resource/include/...sku=PNOTEAC350
its made by APC 350W and 2 outlets. $50 is not too bad too.
