The transmission of electric power via wireless is no more science-fiction. Today it is possible thanks to the development of the technologies that passed from the experimental labs to the mass production. An example is Powermat, a plane surface that transmits to the device the power. After the devices are charged, Powermat will stop send energy to that device, and in this way energy is not wasted.

Thanks to this technology, can be charged up to 3 devices, of different size, and Powermat will deliver the exact quantity of energy.  Magnetic attraction between every receiver and each access point on every mat assures that alignment is precise and the most efficient charging will occur-it’ll be as fast as or faster than the original power adapter. Also is available the option of charging the devices via a USB connection, available on every mat.

Is great news and we will forget about tens of types of chargers, for every device, each with its own shape, size, and voltage.
