Anyone ever use a power inverter to power a laptop using your 12v dc outlet in your truck/car? I found one on Walmart,
http://www.walmart.com/ip/Belkin-F5C...#ProductDetail, that I'm thinking of picking up for an upcoming roadtrip but not sure about it. It says it will kick out 110-v current (household current) but I had one of these before and I thought it was roughly the same power and it couldn't even power my air pump to inflate my air mattress.
If you've had success with a power inverter before what brand and model did you buy? Any recommendations are appreciated.
