Nature shows that whenever water molecules evaporate into a gas the area surface from which this process takes place will cool down as a result. Designers used this law of nature to design the portable cooler. The method is quite easy.

Air is blown thru a surface that suspends a thin layer of water on a fabric like material and allows for quick evaporation to occur. The air conditioner uses a tiny volt charge to turn a fan. This fan sends the air through the wet fabric like area where it makes contact with water molecules.

The air molecules touch the water molecules for a short instant during which the water evaporates from the air molecules, resulting in the air being cooled down. You can feel this effect as it occurs.

Clever design saw all the components of the unit housed in a single plastic casing where all the above mentioned processes happen. For the unit to work, water needs to be replenished to keep the wet fabric wet.

Portability came simply as such a low voltage charge ( 12 volts actually ) can be generated using batteries and or solar chargers. This suggests you can take your cooler with you wherever you go.

This very handy transportable auto Air Conditioner design just proofs that simplicity in technological designs work enormously well. Add to that the fact the unit will never pollute the planet and you will understand the huge sales this cooling system enjoys.
