Dometic CFX3 35 Portable Refrigerator and Freezer 36L Review (2026)

Who the CFX3 35 is for

The Dometic CFX3 35 targets overlanders, van campers and car campers who have already decided a compressor fridge is worth the investment and want a brand with a long history in the category. A 36 liter capacity, which the manufacturer states holds around 50 cans, suits two people on a long weekend or a solo traveler stretching food over a longer trip. Because it can run on AC, DC and solar power, it fits people building out a vehicle electrical system who want a fridge that integrates cleanly with a house battery and solar setup. The app control feature also appeals to campers who want to check or adjust the fridge temperature from a phone without opening the lid or walking back to the vehicle.

Compressor, dimensions and features

According to the manufacturer, the CFX3 35 measures about 15.7 by 27.3 by 16 inches and weighs roughly 37.3 pounds, built with what Dometic calls an ExoFrame construction using aluminum alloy handles for a lighter yet durable frame. It uses Dometic's own VMSO3 variable speed compressor with software described as optimized for efficiency, and the manufacturer lists a temperature range from about 50 down to negative 7 degrees Fahrenheit, allowing it to function as a freezer as well as a fridge. Power flexibility covers AC, DC and solar input, and the companion app lets users monitor and adjust settings remotely over a wireless connection when in range.

Living with it at camp

Setup follows the same pattern as most 12 volt compressor fridges: connect to a power source, set the target temperature through the panel or the app, and let the compressor cycle to hold it steady. Dometic's compressor line has a long reputation among overlanders for consistent, efficient cooling that does not spike battery draw the way cheaper compressors can, which matters on multi-day trips relying on a single house battery or solar panel. The lighter ExoFrame build makes it somewhat easier to load and unload than older all-metal Dometic fridges, though at 36 plus pounds empty it is still a two-hand lift once loaded with food. App control is a genuine convenience for checking temperature from inside a tent on a cold night rather than getting up to check the display.

Trade-offs and rivals

The clearest trade-off is price: the CFX3 35 costs noticeably more than similarly sized fridges from newer brands, which is reflected in its comparatively lower value score in the site's guide despite topping the ratings for features and build quality. The ICECO VL45, which uses a SECOP compressor and offers a larger 45 liter capacity, is the closest rival for buyers who want strong compressor performance without paying for the Dometic name and app ecosystem. Campers who need a bigger single unit for longer trips or larger groups should look at the Dometic CFX3 100, which trades portability for significantly more interior volume, including features like an available ice maker on some CFX3 models.

Verdict and who should pick something else

For campers who want proven compressor reliability, app-based monitoring and a fridge sized for a couple or two on the road, the Dometic CFX3 35 lives up to its strong feature and build scores in the site's fridge guide. Budget-focused buyers who mainly want raw cooling capacity should consider the ICECO VL45, which offers more liters for less money using a comparably respected compressor. Anyone who needs to keep frozen and chilled items at different temperatures simultaneously should look at a dual-zone model instead, since the CFX3 35 operates as a single zone that can be set to fridge or freezer temperatures but not both at once.
