True wireless charging: How does it work?
The Air Charge tech is certainly bizarre, but explainable wizardry. The unit itself is an isolated charging pile that has five-phase interference antennas built-in, which in turn, can detect the location of the smart device. Then, a phase control array with 144 antennas transmits waves directly to the phone through beamforming — a way of focusing wireless signals directly to a receiving device. Xiaomi’s smartphone then converts the wave signal from the charging pile into electric energy through a rectifier circuit, all thanks to a miniaturized antenna array with a built-in “beacon antenna.” Thanks to all that, the Air Charge tech will supposedly still work even if there are obstacles in the way. Regardless, I still like to think of it as the beginnings of The Force. Xiaomi hasn’t provided a launch date or price for the new type of charging tech, but judging by its size and future prospects, we can’t imagine it being cheap.
