I haven't ever looked into these, but I may need to. Where can I get one that will be sufficient to run a regular desktop PC and monitor? I know that sounds rediculous but my emanage engine management system won't link up with my laptop for some reason, but it will link up with an old desktop I am using, and for tuning purposes I NEED to get the thing linked up so I can tune this car so I don't blow another motor on it. Or if someone just wants to sell me a cheapo Laptop with WinXP that would be even better lol.

 

i know radioshack sells some, but not sure on the quality. why not run an extension cord from the house to the car while you tune?

 

if im not mistaken, you are looking for a power inverter. they either plug into the cig lighter or directly to the battery. Check this link out.....has everything u need...
