Using wireless energy is far simpler as it might sound as although some new things have to be installed to the devices that will start to use the wifi electricity and a new device that would start to generate the wireless energy. So more precisely, the devices that will start to be charged with the wireless energy need the tiny adapter controller to be installed in them. And the other thing is the power base station that will also need the contact controller chip to be installed in that one. When taking into account where the technology has developed in this point in time than the system is not yet completely wireless as the base station will still be plugged into a power outlet.
