The Chinese gadget company Xiaomi is bringing a new device for wireless charging, and truly it is according to the name, Mi Air Charge, it allows multiple devices to be charged with 5W power. It differs from the already existing technique where devices only within a specific distance of four centimeters are charged, the widely known Qi standard. This new device will charge many devices simultaneously, even with physical barriers, which means things placed between the charging pile and devices won’t hamper charging, placed within a “radius of several meters.”
Technical Features Of The Device
The device is equipped with an isolated charging pile unit with five phase interference antennas for detecting the location of the devices to be charged. There are 144 antennas in the phase control array for direct transmission of the mm-wide wave to the device through beamforming.

According to the makers, the former will broadcast position information with low power consumption, while the latter will be composed of 14 antennas, which will convert the mm-wave signal given off by the charging pile to electric energy with the help of the rectifier circuit.
Xiaomi aims at extending the charging to other gadgets like smartwatches, wristbands, and other wearables. Even smart home speakers, desk lamps, and more in the future. The makers elaborately said that in the coming days, our lamps, speakers, small home products would get powered wirelessly, making our houses and lives free of them.
