It is the Mi Air Charge system, which can charge a phone with a power of 5 watts within a radius of ‘several meters’ and it supports up to five devices at the same time.
Xiaomi presented this Friday its Mi Air Charge wireless charging technology, which allows the process to be carried out remotely “without cables or supports”. “Today we are entering a real era of wireless charging,” the Chinese company says on its blog.
It is an isolated charging battery developed by Xiaomi itself and equipped with five-phase interference antennas that allow it to “accurately” detect the location of a phone. The 144 antennas it contains “send millimeter waves directly to the device by beamforming,” explains the manufacturer.
To make this technology functional, the equipment to be loaded must have a receiving system. Xiaomi has developed a “set of miniaturized antennas” that convert the signal from the battery into electrical energy and a “beacon antenna” that transmits the positioning of the ‘smartphone’ and uses little energy.
Currently, Mi Air Charge allows to charge a phone with a power of 5 watts within a radius of ‘a few meters’. Supports up to five devices at the same time without physical obstacles reducing charging efficiency.
The electronics giant estimates that this “revolutionary technology”, “completely cable-free”, could work with smart watches, bracelets and other wearable devices in the future. In addition, Xiaomi believes that devices such as speakers, desk lamps and other household electrical accessories will be equipped with external power supplies to “make the whole house wireless”. “This is a revolutionary innovation. It’s not science fiction, it’s technology,” he concludes.
