I tried mine on the Kill-a-watt and it seems to only be around 375 watts.
Just about right.
What I'm curious about is if everyone is just popping the hood a couple times a day to plug/unplug, or if anyone's figured out a better way?
My plug snakes through in front of the radiator, and tucks up behind the bumper when not in use. Stays relatively clean there, and is easy to grab without popping the hood. -- Jim
