Overlanders, RV travelers and vehicle-based campers with reliable 12-volt power have a benchmark in the Dometic CFX3 45. The VMSO3 variable-speed compressor uses less power than a 60-watt bulb, and the cooler freezes down to -7 degrees F. Roughly $950 is the obvious trade-off, but for buyers who stop making ice resupply runs and gain three to four times the cold-storage capacity per cubic foot, the math works.
- — Refrigerates or freezes to -7 degrees F using less power than a 60-watt bulb
- — VMSO3 variable-speed compressor with WiFi and Bluetooth app control
- — Not waterproof; cannot be exposed to rain or dunked
- — Heavy at 41 lbs empty and requires power source to function
