Dometic’s portable fridges have a reputation for being overbuilt and reliable. The CFX3-35L carries that forward, but its real advantage is how it simplifies power management. The three-stage battery protection system is smart enough to monitor your vehicle’s voltage and automatically shut down before you’re stranded.

It can freeze contents down to -7°F, which is overkill for drinks but perfect for preserving fish or ice cream on a multi-day trip. The 35-liter capacity fits about 40 cans, plus some food. You control it all from the CFX3 app, letting you adjust temperature or check power draw from your phone. The compressor is quiet, drawing about as much power as a car stereo on a hot day.

The ExoFrame construction feels solid, though the plastic shell can pick up scuffs. This is a premium tool for camping or overlanding where a dead battery isn’t an option. For tailgating, its deep-freeze capability is likely more than you need.
