In detail: Mobicool MQ40W Portable Electric Cooler 39L
The Mobicool MQ40W carries the name of Mobicool, the consumer-facing brand of the Dometic group, a historic and global reference for mobile cooling in cars, boating and motorhomes. That heritage translates into proven technical know-how, applied here to a 39-litre thermoelectric electric cooler.
Its generous capacity, larger than most entry-level electric coolers, covers the needs of a family over a weekend or several days of holiday, without having to carry multiple coolers. Dual 12V (cigarette lighter) and 230V (mains) power supply offers real flexibility of use, in a car, campervan, boat or at home on a standard socket.
The compact format with built-in carry handles makes the unit easy to move despite its generous capacity, an important point for regular use between the car boot and the destination.
The Mobicool MQ40W stands out as one of the most popular references in the thermoelectric electric cooler segment, carried by trust in the brand and a level of popularity well above the market average.
