Take food and drinks on the go without having to buy bags of ice with the Koolatron Kool Kaddy Wheeler 12V Plug-In Cooler featuring a thermoelectric cooling unit. The 34L (36 quart) capacity cooler plugs into your car's cigarette lighter to keep your snacks and drinks cool no matter how long your trip. The cooler can be used two different ways - sit it horizontally and use it as a chest-style cooler or turn in on its end, insert the sliding shelf and use it like a small fridge! The built-in wheels make it very easy to take the cooler with you outside of the car too.
