The Dometic CFX3 45 is the fridge that quietly ruins coolers for you. After a summer of weekends and a couple of longer trips, what stands out isn't any single feature — it's how little you 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 our house battery it ran 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.
FAQ
Is the CFX3 45 big enough for two people?
Yes. At 46 litres it holds several days of food and drinks for two, especially if you shop along the way. For longer trips or families, step up to the 75 L dual-zone model.
