In detail: Dometic CoolFreeze CFX3 35 Wifi-Connected Compressor Cooler
The Dometic CoolFreeze CFX3 35 belongs to the connected generation of compressor coolers: beyond the classic performance of a compressor-driven cooler, capable of reaching sub-zero temperatures, it comes with a Wifi module that lets you monitor the internal temperature and adjust settings remotely from a smartphone, via the dedicated CFX3 app.
With a capacity of 36 litres, it offers comfortable storage space for a multi-day stay in a van, motorhome or boat, while remaining portable thanks to its ExoFrame structure and folding aluminium handles, designed to reduce the perceived weight when handling compared with bulkier models.
Power supply is particularly versatile: 12V and 24V for connecting to the vehicle battery, 230V for mains use, and solar compatibility for anyone who already has a portable photovoltaic setup. This flexibility makes it a relevant choice for van conversion or motorhome enthusiasts who prioritise energy independence.
The remote monitoring function via the app is the main differentiating feature of this CFX3 generation: it lets you, for example, check that the temperature stays stable while away from the vehicle, or adjust the setting before even getting back to it. A modern convenience that comes with a higher price tag than compressor coolers without connectivity, to be chosen according to how much value you place on this remote monitoring.
