Life does not stand still, and people for various reasons spend a long time in their car. Someone's work involves long trips. Someone loves to wave far away for the weekend. Many parents prefer traveling with their young children in their car: it’s convenient, you don’t have to spend tedious hours in the airport lounge or shake in a stuffy train carriage. It also allows you to visit areas where there are problems with public transport. In these cases, there is a need to store the products in the vehicle. A cooler bag powered by a cigarette lighter is a great option in the absence of standard outlets.
Car refrigerators: types
Depending on the purpose and frequency of operation, you can choose the right device for yourself. Manufacturers, taking into account the preferences of different categories of car owners, produce a wide variety of refrigerators for use in the car: portable freezers, spacious stolitrovye containers, small convenient thermobags, and even cigarette lighter powered devices with built-in radio. Consider their main types:
- Soft thermobags are the simplest cooling devices. Available in various shapes and sizes: the volume of such devices is from 5 to 80 liters. If the cooler bag powered by the cigarette lighter is able to cool the contents, then its relative maintains the initial temperature of the products due to the insulating layer. Suitable for transporting food and drinks, for outdoor trips.
- Thermal containers: large thermos in the form of a box. They do not need electricity, they are lightweight and easy to carry. They do not cool the contents, but simply keep the original temperature. Available in volumes from 5 to 150 liters.
- Thermoelectric cooler bag powered by a cigarette lighter: the cooling is based on the so-called Peltier effect, named after the French scientist who discovered it. The heat from the products is brought out and dissipated using a cooler. The degree of cooling depends on the environment. The temperature difference in the refrigerator chamber and outside does not exceed 20 0 . If it is necessary to cool the contents below three degrees of heat, it is necessary to additionally place a cold accumulator in the chamber .
- Compressor car refrigerator. This is not just a cooling bag. A fridge powered by a cigarette lighter or a car battery can freeze foods to -18 0 . The smallest of this family are designed for 10 liters. For the largest, with a volume of 100-110 liters, you will need free space in the cabin or trunk. Cons are the high price and ability to put the battery in a short time.
Optimal solution
Based on the characteristics of the produced models - their price, dimensions, impact on the battery and cooling capacity - it becomes obvious that the cooler bag, which works without interruption from the cigarette lighter, is the best choice. Many models can work both for cooling and heating. They are available in volumes from 5 to 50 liters and can be used by both families and people traveling alone.
