Koolatron, cooler heater combo unit. Works great! 120v. I just plugged it in for an hour and it was really roasty, then flipped the ac plug in upside down, the other way, as it states on the side, and 1 hour later, nice and cool! 16" wide x 15" high x 15" deep. A good size to hold alot of beers! Or milk?! Pretty good shape. $40
