In detail: Severin KB 2922 Thermoelectric Electric Cooler, 19 Litres
The Severin KB 2922 electric cooler suits those looking for a compact solution for short trips or brief stays, without needing a large volume or extreme cooling performance. With its 19 litres and dimensions of 28.5 x 40 x 42 cm, it's easy to fit into an already loaded car boot and to store once the trip is over.
Its distinguishing feature, compared with many competing electric coolers, is its reversible function: it cools up to 20°C below ambient temperature, but can also keep food warm at around 60°C, a real plus for carrying a cooked meal without having to juggle several appliances. The dual power supply, 12V from the vehicle's cigarette lighter socket and 230V mains, cables included, lets you use it both on the move and on arrival at your holiday destination.
Its power consumption of 58 W in normal operation drops to 8 W in eco mode, a welcome option for nighttime use with no noise disturbance: the stated noise level stays around 35 dB(A), one of the lowest in its category. Note that its energy class is labelled E on the new European scale, which corresponds to the old A++ class still sometimes displayed by some retailers: an annual consumption of about 70 kWh, consistent for this type of appliance.
The German brand Severin, historically well known for small appliances, applies the same standard of reliability to its range of electric coolers, as shown by the number of verified reviews accumulated on its product listing. This type of appliance particularly suits a couple or small family on a weekend, where a 19-litre volume is enough to keep a few drinks and basic food items without excess. Simple to use, with a cooling or heating selector button and an indicator light showing the active function, this electric cooler is aimed at users who value simplicity and versatility over the advanced features of a pricier compressor model.

In the segment of small 12V/230V thermoelectric electric coolers, the Severin KB 2922 regularly comes up against the Dometic BordBar AS 25, the other accessible reference in our selection, in searches such as "Severin vs Dometic electric cooler". Here's how the two compare, based on the public specifications of both manufacturers.
| Criterion | Severin KB 2922 | Dometic BordBar AS 25 |
|---|---|---|
| Capacity | 19 litres | 20 litres |
| Power supply | 12V / 230V | 12V / 230V, automatic switching |
| Consumption | 58 W, eco mode 8 W | 47 W (12V) / 55 W (230V), eco 7.5 W |
| Temperature gap | Up to 20°C below ambient, plus heating function (60°C) | Up to 18°C below ambient (cooling only) |
| Noise level | ≈35 dB(A) | ≈39 dB(A) |
| Weight | ≈4 kg | ≈4.3 kg |
| Price observed | ≈€96.71 | ≈€99.99 |
In short, the Severin KB 2922 stands out for its reversible heating/cooling function, a lower noise level and a slightly wider cooling-only temperature gap, while the Dometic BordBar AS 25 relies on automatic switching between power sources and its dedicated internal freezer compartment. The two remain very close in weight and price: the choice will mainly depend on whether the heating function matters to you.
Our tester's verdict: Gilles Caron
With several thousand verified reviews on its product listing, the KB 2922 is by far the most reviewed electric cooler in our selection, and overall feedback confirms what we found in use: it does the job without fuss. The heating function is the real plus over a standard electric cooler, handy for carrying a hot cooked meal rather than betting everything on cooling. The 8 W eco mode makes it discreet for a hotel night or an overnight drive, and the noise level stays contained even during normal operation. Two points to know before buying: its E energy class on the new European scale, less flattering than the old A++ still displayed by some retailers, and cooling that remains that of Peltier technology, effective for keeping already-cold products cool but not for turning a warm drink into an ice-cold one. For occasional use, a weekend, a holiday road trip, a top-up in a hotel room, it remains a reliable and affordable choice.
