It is a small air conditioner, it is a 14 cm cube, silent and does not require power. With a cost of just 2 cents it promises to cool a room of approximately 12 square meters by 3 degrees, giving a minimum of relief from the heat but without the contraindications of a normal air conditioner. Its operation is very simple, it is a cube made up of two components inside which there is a small fan and where a eutectic plate is inserted, that is, one of those plastic elements that accumulate the cold and which are used in "cool bags". ”. The air is cooled and then pushed through 360 degrees. Its battery recharges via USB and consumes the equivalent of 2 euro cents in electricity. It does not have on and off buttons: just insert the ice-pack - previously frozen in the freezer - into the lower half of the cube, arrange the two halves on top of each other, making the two on marks coincide in order to close the circuit electric. To turn it off, simply lift and rotate the lid again. The color will be sent based on stock availability.
