Yes, you are correct here, and Jeff, as an EE understands KW and KWH, however the deceptive wording of the puff story makes it sound like he was getting 17 KWH, and never mentions that he only had a 1 KW inverter. It also makes an incorrect comparison between the "Delco" battery of a normal car and the special battery of the prius, with no concern for the fact that the only 12 volt battery the Prius has, is a gel cell not much bigger than a motorcycle battery, and considerably smaller than the Delco. You can buy into this garbage if you so choose, but some of us live in the world where laws of physics matter
