Freezers

when choosing a car refrigerator, pay attention to how many volts it works on. folds can be different:
12v (volt) refrigerators work in vehicles with 12v current from the cigarette lighter socket, which are passenger cars, vans.
24v (volt) car refrigerators work in 24v vehicles, which are trucks.
220/230/220-240v gives the possibility to use the refrigerator at home directly from the wall socket.

if the refrigerator does not have a 220-240v option, but you still want to use it at home, you need to purchase an additional voltage transformer, which is installed in the wall socket at home and has a special socket with the possibility of installing a 12v cigarette lighter. the transformer also converts 230v current into 12v current suitable for the refrigerator.

car refrigerators are generally divided into those that do not have the possibility of a deep freezer and that generally cool the temperature to about 16-20 degrees lower than the ambient temperature (thermoelectric refrigerators). i.e. if it's 30 degrees in your car, it's 10-14 degrees in the fridge. cooling-only refrigerators generally also have a heating function that helps keep the temperature in the refrigerator up to 65 degrees. you can keep your food warm by using this function.
in addition, there are car refrigerators with a freezer function that cool down to minus degrees. such refrigerators are significantly more expensive.

some modern car refrigerators also have USB sockets for charging, bluetooth and wifi interfaces, which you can use to set up and monitor the refrigerator's operation with your phone.

as additional functions, the car refrigerator can also have interior lighting, operation on gas, LED screen.
