Wax On, Woot-Off
Charges things from the power of your car, but does not charge your car itself. Sorry if that wasn't clear from the name.
We were giving our warehouse its spring cleaning, its vernal sprucification, its annual zhuzhing - and look at this crazy gunk we scraped off the shelves! This Woot-Off promises to be full of surprises! (And now that we've said that, a complete lack of surprises would, itself, count as a "surprise". Called it.)
