Need a power cable for laptop so that I dont have to worry about battery wearing down while at the track. Where do you get it from, or how do you make one?
Do you have the cable that plugs into the wall?
If not you'll need to contact the manufacturer for that.
If you do have it, then all you need is one of those little adapters that plug into the cigarette lighter that you can plug that cable into.
I got mine from Wal-Mart...works just fine.
Hope that helps.
