FORGET A COOLER FULL OF ICE: The thermoelectric system in the Cooluli Cooler and Warmer allows for easy switching from beverage cooler to food warmer! Ideal for use on camping and road trips, picnicking, or for people who spend time in their vehicles. Keep your drinks cold and refreshing, no ice necessary! Not to mention it holds up to 12 12-ounce cans or whatever else you want to bring on your next road trip.
EASY SWITCH FROM COOLING TO HEATING: Take the cooler/warmer on the go and transition from cooling to heating with the flip of a switch! Easily fits in the back seat and plugs into the cigarette lighter with the included 6 and a half foot DC power cable to reach the back seat in any car regardless of the size. Cab and truck drivers love our product to keep them on the road and avoid wasting time and money at rest stops.
