In detail: Dometic BordBar AS 25 Thermoelectric Electric Cooler, 20 Litres
The Dometic BordBar AS 25 is a 20-litre thermoelectric electric cooler, not to be confused with a passive insulated bag: it's a genuinely powered appliance that keeps things cold continuously, with no need for ice packs. It belongs to Dometic's BordBar range, alongside smaller models such as the TB 08 (8 litres) or the TF 14 (14 litres), all built on the same Peltier module technology.
Its dual power supply, 12V from the vehicle's cigarette lighter socket and 230V mains, with automatic switching between the two sources, lets you use it both during a journey and on arrival at your holiday destination. It cools up to 18°C below ambient temperature, enough to keep already-cool drinks and food chilled, without reaching the sub-zero temperatures of a compressor cooler. A compact internal compartment of about 10.5 litres acts as a small freezer for the most sensitive items.
Its power consumption stays reasonable for the technology, 47 W maximum on 12V and 55 W on 230V, with an eco mode down to 7.5 W for quieter nighttime use. The noise level, around 39 dB(A), keeps it generally quiet on 230V, though several users report louder operation on 12V at full power. Compact at 28 x 39 x 43 cm for about 4.3 kg, it attaches easily to the passenger seat or rear bench using Velcro fastenings and can be strapped in with the vehicle's seatbelt, in addition to its shoulder strap for carrying.
This cooler particularly suits car journeys, shopping trips, picnics and short stays where access to a mains socket or cigarette lighter is guaranteed. Like any Peltier technology, it remains less capable than a compressor model for heavy use or prolonged high heat, but its compact format and dual power input make it a simple, accessible solution for occasional use.

In the segment of small 12V/230V thermoelectric electric coolers, the Dometic BordBar AS 25 regularly comes up against the Severin KB 2922, the other accessible reference in our selection, in searches such as "Dometic vs Severin electric cooler". Here's how the two compare, based on the public specifications of both manufacturers.
| Criterion | Dometic BordBar AS 25 | Severin KB 2922 |
|---|---|---|
| Capacity | 20 litres | 19 litres |
| Power supply | 12V / 230V, automatic switching | 12V / 230V |
| Consumption | 47 W (12V) / 55 W (230V), eco 7.5 W | 58 W, eco mode 8 W |
| Temperature gap | Up to 18°C below ambient (cooling only) | Up to 20°C below ambient, plus heating function (60°C) |
| Noise level | ≈39 dB(A) | ≈35 dB(A) |
| Weight | ≈4.3 kg | ≈4 kg |
| Price observed | ≈€299 (marketplace offer, worth checking) | ≈€96.71 |
In short, the Severin KB 2922 stands out for its reversible heating/cooling function, a slightly wider temperature gap in cooling-only mode, and above all a much more affordable price. The Dometic BordBar AS 25 relies on its seatbelt mount and dedicated internal freezer compartment, but its observed price has risen sharply and now puts it well above the Severin: at an equivalent budget, the KB 2922 is the more reasonable pick, the BordBar AS 25 being justified mainly by its mounting system or a brand preference.
Our tester's verdict: Gilles Caron
Brought along on a road trip to northern Europe, this Dometic BordBar AS 25 first ran off the van's cigarette lighter socket through the long stretches, before switching automatically to mains power once plugged in at a serviced stopover. The seatbelt mount on the passenger seat proved genuinely useful through mountain bends, the unit never budged. It kept already-cold drinks and food from a campsite fridge nicely chilled, but never turned a warm can into an ice-cold one, a familiar limitation of Peltier technology I already knew about. On mains power, noise stays discreet, almost unnoticeable once the door is shut; on the cigarette lighter, though, the hum becomes noticeably more present, especially with the engine off. The small 10.5-litre internal freezer compartment proved handy for keeping ice packs ready in reserve. For short to medium trips, used alongside a proper compressor cooler, it remains an honest choice, provided you check the price at the time of purchase: the going rate has climbed noticeably lately against comparable competitors.
Frequently asked questions: Dometic BordBar AS 25 Thermoelectric Electric Cooler, 20 Litres
No, it's a thermoelectric electric cooler: it must stay plugged in, either 12V to the cigarette lighter or 230V to the mains, to keep things cold. Unplugged, it behaves like a simple insulated cooler with no active cooling.
It's designed for continuous operation, for as long as the power source allows: on mains (230V) with no time limit, on the cigarette lighter (12V) while keeping an eye on the vehicle's battery level to avoid draining it if the engine stays off for a long time.
Up to 18°C below ambient temperature, a typical performance for Peltier technology coolers. It effectively cools already-mild products, but doesn't reach the sub-zero temperatures of a compressor cooler like an Engel or a Dometic CoolFreeze CFX3.
The manufacturer states about 39 dB(A), a discreet level on mains power. Several users do report louder operation on 12V at full power, though it's less noticeable once the vehicle is moving.
