The Dometic CFX3 45 is the fridge that quietly ruins coolers for you. Across the spec sheet and years of owner threads, what stands out isn't any single feature — it's how little owners have to think about it.
Cooling and efficiency
It pulls down to temperature fast and holds it without drama. The real win is insulation: the compressor cycles less, so it sips power. On a typical 100 Ah house battery it runs comfortably for days between charges.
Living with it
App control is genuinely useful for pre-cooling and monitoring, and the low-voltage cutoff means it can't flatten your battery. The build feels overengineered in the best way.
Worth it?
For occasional campers, cheaper fridges make sense. But if you're out often, the CFX3's efficiency can save you the cost of extra battery capacity — and it's a joy to use.
