How to choose a car refrigerator
A refrigerator for vehicles is not an essential item; it is necessary for people who travel a lot or in cases where work involves long journeys.
Car refrigerators can be in the form of a regular cooler bag, or connected to a cigarette lighter and powered by electricity. The bag will keep the cold for the time allotted to it by the manufacturer, and the refrigerator powered by the network will independently produce a cooling effect on the food, like a regular home refrigerator, only several times less.

Types of car refrigerators
Mini-refrigerators that connect to a vehicle’s cigarette lighter have several types:
- Thermoelectric models. Inside there is a small fan and a thermocouple, which comes into operation either from the power supply or from the cigarette lighter. Consumption of energy reserves is low. Takes up little space. The only downsides are that it can’t freeze and cools rather slowly.
- Absorption models. It operates from the same sources as the previous type, but adds the ability to operate using gas. Refrigerant circulates inside the tubes, which allows for rapid cooling of products.It is also quite compact and wastes little energy. Sensitive to tilts exceeding 30 degrees - it stops working due to impaired refrigerant movement.
- Compressor models. Freon acts as a refrigerant, so the structure of this type resembles a conventional refrigerator. There's plenty of space inside and cooling is quite fast. The negative features of this choice are weight and rather high price. These models do not run on gas.
- Hybrid equipment - an expensive option that offers the owner several cooling options.
We recommend choosing a car refrigerator with a compressor.
Advantages of a cooler bag
Spending a long time in the car leads the driver to the idea of purchasing a cooler bag. This is especially true for avid fishermen, hunters or just travelers.
Thermoboxes help keep food fresh during relatively short trips. There will be enough supplies for a small group of people, especially since there may be several such bags. Why choose a cooler bag:
- low cost;
- ease of use;
- keeps food warm for up to five hours;
- connects to the cigarette lighter;
- can be used for a long time, for example, when traveling.
What is the difference between isothermal bags?
Such bags keep food warm for a certain amount of time and work like a thermos. It is convenient that such models can be used without connecting to a power supply. The bag will help maintain the temperature for a short time.
On what principle do adsorption models work in a car?
These refrigerators contain a pump inside that is driven by heat, which combines with refrigerant and hydrogen to create pressure.Such models can also heat food if necessary, and their operation in cooling mode is not interrupted. Moreover, the models can operate both from a household outlet and from a cigarette lighter.
Conveniently, the design of this refrigerator is closed, and no parts interfere with its installation where it is convenient for the driver.
Pros and cons of low temperature chambers
Such models are shock-resistant. Can be connected to the cigarette lighter and to the power supply. Depending on the type, gas operation is possible. It is convenient to use, but the disadvantages include its rather high price.
