So far The Wireless charging Comes in the form of a docking station or dock where you need to place your smartphone. The latter must actually interact with the load support so that the energy generated by the station’s coil goes on its own. A major drawback compared to a traditional wired connection is that it is not really possible to use it while charging the device.
With its Mi Air charger, Xiaomi transforms the game. The Chinese manufacturer has designed a box with five antennas that can locate the smartphone; 144 other antennas can then transmit millimeter waves to recharge the battery.
For its part, the associated smartphone is a ” Beacon Capable of sharing its position with the box – so precisely the location of the earth – and converting the millimeter waves received by 14 antennas into energy.
Currently, the technology allows charging at 5 watts from a distance of several meters. Of course, this is not much compared to the 65 watt wire chargers, in full expansion, but at home, the smartphone continues to operate.
Xiaomi also explains that it is possible to charge multiple smartphones (5 watts each) at the same time. The performance of the recharge will not be affected by the objects placed in front of the case.
