Title: Make sure your car has a 15 amp power socket.
Review: The first time I used it it blew my car's cigarette lighter socket fuse. It turns out your car must have at least a 15 amp socket, and my Honda does not (it's only 10 amps). So I had to go to Radio Shack and buy a socket that connects directly to the car battery with alligator clips. (Amazon sells one called a "12V Battery Clip-On and Cigarette Lighter Adapter"). When I used that it worked fine.
