At the first glance, I thought I was some kind of aquarium filter. No it’s not. It is a Plug-In Commuter’s Warming and Cooling Mug, a car cup holder which can heats a cup of drink to 140 F and chills to 40 F in minutes. It comes with Hot/cold/off switch and gets its power from the cigarette lighter socket. Available for $25.
