You drop the CFX3 35 from Dometic Group AB into the back of the car, slam the tailgate and hear a quiet hum instead of the rattle of ice packs. The lid feels solid and slightly textured under your fingers, more like a travel suitcase than a camping box. In the evening, its white LED light floods cold air over neatly stacked drinks and a half-melted tub of ice cream that somehow still holds its shape.

Compact compressor, real freezer

The CFX3 35 is one of Dometic's compact compressor coolers, offering around 32 liters of usable volume in a footprint that fits between the wheel arches of many estate cars. Inside, a removable wire basket and divider help you keep food and drinks separated instead of tumbling together. The walls feel thick and robust when you rap your knuckles on them, a reminder that high-density insulation is hiding inside.

Unlike passive cool boxes, the CFX3 35 uses a variable-speed compressor that can cool from +20 °C down to around -22 °C, turning the box into a genuine portable freezer for ice cream or meat. According to Dometic, the unit runs on 12/24 V DC or 100-240 V AC, which means a single product covers car, boat and home use without adapters.

Controls, app and display

On the front, a color display shows temperature, operating mode and battery protection level, with rubberized buttons that give a clear click under the thumb. Product manager Alexander Bengtsson has emphasized in Dometic materials that the CFX3 line was designed to be controlled without a manual in hand, and the menu structure reflects that aim. You see temperature, tap up or down, and the compressor quietly responds.

The cooler also talks to the Dometic CFX3 app via Bluetooth, letting you set target temperatures, check battery status and receive alerts if the lid is not properly closed. In practice, this is handy when you are sitting at the campfire and wonder whether the steaks are still at -5 °C. You open the app, glance at the graph and decide whether to nudge the temperature or leave it.

Battery protection and power draw

Dometic equips the CFX3 35 with a three-stage battery protection system that shuts the cooler down before your starter battery drains too deeply. You select low, medium or high depending on whether you are on a dedicated auxiliary battery or the main vehicle battery. For many van owners, this is the difference between a cold breakfast and a call to roadside assistance.

Power consumption naturally depends on ambient temperature and setpoint, but the CFX3 line is specified with modest average draw thanks to the variable-speed compressor and improved insulation. Longtime reviewer Jan Höglund has noted in field tests that the CFX3 35 can run for a weekend on a mid-sized AGM leisure battery if you avoid permanently freezing at -22 °C and instead hover around fridge temperatures.

Build quality and ergonomics

The outer shell combines ABS plastic and reinforced corners, aimed at surviving being dragged over gravel or knocked by a mountain bike pedal. Two spring-loaded handles fold down neatly when not in use, so the cooler does not snag on cargo nets. When you lift the box with a partner, the weight feels manageable for its class, though single-handed carrying gets tiring once fully loaded.

The lid uses a spring-lock mechanism with a wide latch that is easy to grab even with cold or greasy fingers. A soft-close feel is missing; you need to press until you hear a clear click, which reassures but may annoy users expecting a smoother motion. Inside, the integrated LED light illuminates the contents in a clean white tone, which makes it easier to distinguish the yogurt from the mayonnaise in the dark.

Price, availability and target users

The CFX3 35 sits roughly in the mid-range of Dometic's CFX3 portfolio, below bigger siblings like the CFX3 45 and 55 but above smaller units aimed at day trips. Retail prices in Europe typically hover around the mid hundreds of euros, with variations between outdoor chains and online retailers. In Germany and wider EU markets, the cooler is available through camping specialists, automotive accessory retailers and Dometic's own online channels.

Target users range from weekend campers and vanlifers to small-boat owners who want reliable cooling without installing a permanent fridge. Compared with cheaper thermoelectric coolers, the CFX3 35 offers freezer capability and faster pull-down, at the cost of higher upfront price and the need to plan battery capacity. Many users treat it as a semi-permanent fixture in their vehicle, moving it only when seasons change.

Stock context and market angle

For Dometic Group AB, portable compressor coolers like the CFX3 35 sit at the intersection of camping, automotive and marine markets, reinforcing the brand in several ecosystems at once. Dometic Group AB shares (ISIN SE0007691613) trade on Nasdaq Stockholm in Swedish kronor, giving investors direct exposure to this mix of leisure and mobile-living demand.
