However, electric cool boxes may have the option of either cooling or maintaining food at warm conditions. Theses boxes could vary in size from a small portable one to big family ones that are wheeled.

Thermoelectric System Of Cooling

Best-Electric-Cool-Box

Invention did not stop on the latter cool box. Thermoelectric coolers then came into being. These coolers require a power supply for them to operate. Therefore they are plugged into the vehicle's cigarette lighter socket. The system however guaranteed longer durations of cooling than their predecessor, increasing the popularity of this technology to new and upcoming brands.

These coolers incorporate the use of an external fan, used in drawing heat away as well as the Peltier effect to keep the contents of the box cool. This process, though, can be reversed, and by so doing the cooler becomes a warmer for foods.

This, however, comes at a price as the coolers are known to draw a lot of the car's power. Suppose the vehicle owner forgets to switch the cooler off, and the car engine is not running, the cooler may draw all the electric charge from the battery to the point it can't start the car without jumping it. This necessitated the incorporation of an off switch to the cooler on low voltages. This works perfectly.

It should also be noted that some coolers use a thermoelectric system of cooling, but do not incorporate the heating feature in their system. The heating aspect of a cool box increases its market appeal. However, not all people looking for a cool box are interested in the heating feature.

Some of this coolers come with an adapter containing a transformer which converts AC mains to 12 volts.

Benefits Of Using An Electric Cooler

  • Maintains food and drinks at a cool temperature. Thermoelectric boxes are able to keep temperatures at as low as 40°F below the ambient temperatures. These temperatures are sufficient to keep food and drink cool enough as they left the refrigerator.

  • Keeps beverages at warm temperatures. Electric coolers can raise the temperatures within them to a good range of the ambient temperatures. This feature comes in handy when you have ordered take out, and you do not want to eat it immediately.

This feature may also come in handy in very cold places, as it may protect its contents from freezing.
  • May be used for carrying medical supplies that require being maintained at a cool temperature. Suppose you have diabetes, or there is one in your family, an electric cooler can be used to store their insulin so that they may be able to access them whenever they are in transit.

Electric coolers are undoubtedly very beneficial. Different brands have flooded the market claiming to have the best cooler out of all.
