I know about the LM7805 to wire usb ports into the car, but is there an equivalent for 12 volt to 120 volt? Or do I have to build one?

You'll need a power inverter. You can mount it in your trunk like an amplifier, run it straight to the battery for the best power. A decent one that will run just about anything except a microwave will cost about $30-40. Then plug an extension cord into one end and strip the other end off and wire on your own receptacle and cut a hole somewhere like in your center console. That's what I did anyways.
I'm putting one under the passenger seat. I need to power 2 laptops and the occasional random other items. I figure that I want 800 watts of power is more than enough for my needs, but your needs are probably less.
I was able to run a desktop PC, laptop, and CRT off of a 400 watt peak inverter. 800 watts should do nicely.Originally Posted by Vanilla Sky
Just hack off the lighter socket end and solder it to a 12v wire? Also, what's the easiest way to get the power to my dash 12v plug to shut off when I shut the car off? I hate having to unplug stuff so my car doesn't die overnight.
your best bet is to tap off the fuse panel...i used the radio fuse to power my radar detector

No, wire it off your battery and put a relay in line with a switch on your dash. Then you can flip the switch on and off to turn off the 120v setup.
