The Best Electric Cool Box to Buy with Reviews

An electric cool box has significantly revolutionized from their invention in the 50s. This is basically a portable box that mimics the functionality of a refrigerator. 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.

Earlier boxes were simply made from plastic, stuffed with foam in between the walls. These boxes required no electrical power to keep them functioning, but they relied on the foams insulating characteristics. Ice cubes or ice packs would be placed inside the boxes to keep the contents cool.

Thermoelectric System Of Cooling


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.

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