If you are thinking of getting one yourself cooling boxyou’ll soon find out that’s not so easy. There is a very large, almost unmanageable offer in the market. The cool boxes differ in quality as well as in price and functionality.

In order to make the purchase decision easier, one should subject the cool boxes to a direct comparison.

Funtionsweisen

The absorber cooler.

The absorber cooler works similar to a fridge, In a closed system, a refrigerant is first liquefied and then vaporized using electricity or gas to produce the refrigeration.

The Peltier cooler

The Peltier cooler uses a thermoelectric converter that, when in operation, conducts the heat from inside to outside to provide cooling inside the box. This system is the most widespread and, due to the simple principle, also very favorable. However, the cooling in this Kühlboxart strongly dependent on the ambient temperature.

The compressor cooler

This cool box has, as the name implies, on a compressorwhich compresses a gaseous refrigerant. In this liquefaction, heat is released. Subsequently, the coolant is converted back into a gaseous state of matter with an evaporator, wherein the interior of the cooling box is cooled. The functionality is comparable here with a refrigerator.

At this point, I would like to focus on two Mobicool Peltier coolers and introduce you to two good models. Of course, there are also very good models from other manufacturers, but for which you decide is above all a matter of your taste.

Mobicool W40 Electric trolley Cooler (available at Amazon, among others)

This cool box has a sufficiently large volume of about 39 liters and a divisible lid that keeps the cold loss when opening the box low. Two sturdy wheels and fold-out handles ensure safe and comfortable transport of the Mobicool box. With this box you can cool your cold goods to 18 ° C below ambient temperature. The box is powered by 12V (car or caravan) or 230V (socket) and has the energy efficiency class A ++. A removable divider ensures order in the cool box. With 8.4 kilograms, it is rather a lightweight among the comparable boxes and yet stable.

Mobicool B40 Hybrid Thermoelectric / Compressor Cooler (available at Amazon, for example)

If you are one of the less decision-making people, maybe the Mobicool hybrid cooler B40 is just the thing for you. As the name already reveals, this is a hybrid cooling model, which is technically superior to the normal Peltier cooler. With this cooler even the freezing of the contents at -15 ° C is possible regardless of the outside temperature, but also the normal cooling mode. For mobile use, you can also operate the box with 12V (car or caravan). So you do not have to interrupt the cold chain. For mobile use, the cool box still creates a temperature drop of 20 ° C below the ambient temperature. The housing is made of coated sheet steel and is visually appealing. The size is designed sufficiently large with 40 liters of content. Side recessed handles ensure safe transport.
