Powered 12 Volt Cooler, 46L The award winning powered cooler for weekend camping, the Dometic CFX3 45 electric cooler has the same footprint as the 35, but is 2.75 inches taller. Powered by AC (110-240), DC (12 volt / 24 volt), or solar, the car fridge freezer reaches temperatures as low as -7°F, while using less power than a 60W light bulb. Its lightweight fender frames and strong aluminum alloy handles are designed for rough backroads, while the high-performance compressor is constructed to isolate noise and reduce vibrations. The CFX3 electric car cooler series connects to a phone app, allowing easy temperature adjustments via Bluetooth.
