What are 12 volt freezers?
The built of these freezers are similar to the portable ice chests. These freezers are portable electronic/battery operated appliances and are small to medium sized. These freezers help in keeping the food and beverages cool and fresh irrespective of the outer/ room temperature. These refrigerators have an air intake port and a thermoelectric unit which keeps the interior temperature of the refrigerator lower than the ambient temperature. These appliances have a 12 volt cooler fitted in them which reduces the freezer’s temperature by circulating the formed cool air inside the freezers. The cool air which gets distributed inside the freezer is formed by the thermoelectric plate and fan fitted on the back side of the freezer. The air formed enters the interior compartments of the portable refrigerator through a duct connected to the fan.
The working
The main mechanism behind the functioning of 12v freezers are the thermoelectric units. The thermoelectric units have two plates in them which are different types of semiconductors and these together create a heat pump. One part of the thermoelectric units heats up while the other cools down, depending on the direction of the current any one side gets cool down. Aluminum fans are then attached to the units which distribute either the heat or the cold which has been already produced by the units. The fans are connected to a duct which channelizes the treated air into the insulated chambers of the freezer. Through this process the temperature inside the freezers can be lowered up to several degrees than the outside resident temperature. The entire cycle of heat production of the thermoelectric units are done through switching on and off the power plug.

Disadvantages
Like every other product available in the market, the 12volt freezers too have their share of critics along with their share of admirers. One of the biggest disadvantages of these is that the food items stored inside take a long time to get cold or frozen. So it is advisable to cool the food items beforehand in bigger refrigerators and then store them in 12v freezers whose temperature should be set at minimum degrees.
