    What about 12V DC Outlets that are built into the car?

    My civic has one 12V DC Outlet in the car (it looks like a regular home outlet). Will this be able to power my comp?

    Regular home outlets are not 12 volts DC, they are 110 volts AC in the US, 220 elsewhere.

    If it looks like a home outlet, it'd be AC. Use "the brick" for morex's, that converts AC to 12v DC at 5 amps. Then you can plug that right into your morex/pw70a. Or if you don't have those PSU's, and you use a standard ATX PSU, you can just plug it right into that plug. I don't know much about AC in a car, but I don't think you need (or that there's any possible way/any need) to regulate it. I think since it's AC, you're good to go. Anybody else?

    it's probably AC ... a lot of cars are puting inverters in now.

    i always think converting from DC to AC just to take it back to DC is a waste.

    there's many other 12v sources in your car (i.e. the cig lighter)

    It's a waste of valuable amp hours, not of money... The regulation you get from doing this can be very expensive... and my inverter was cheap.

    I would suggest you look for the output specifications to see if it can handle your pc. I imagine it was purposed for a laptop and is anywhere from 85 - 100 watts. Pay attention to the continuous and peek ratings.

    Good Luck,

    The Pontiac Vibe also has AC outlets in it. I've never heard of anybody using it to power a computer though.
