Keep food fresh with a small electric cooler built for rugged outdoor use. The Dometic CFX3 35 12 volt cooler can be used as a car fridge freezer, reaching temperatures as low as -7°F, while using less power than a 60W light bulb. Dometic’s CFX3 is the best single zone electric cooler for camping and can be powered by AC (110-240), DC (12 volt / 24 volt), or solar power. The powerful compressor in the offroad-ready cooler was built to isolate noise and reduce vibration, while the CFX3 series’ user-friendly phone app means that you can monitor and adjust temperatures while relaxing comfortably at camp.
