Xiaomi Announces Remote Wireless Charging named ‘Mi Air Charge’

Xiaomi has developed an isolated charging pile unit with five phase interference antennas, which can accurately detect the location of a smartphone. A phase control array with 144 antennas then transmits millimeter-wide waves directly to the phone through beamforming.

The remote charging technology is capable of charging multiple devices within a radius of several meters, with each device able to receive 5W of power. Xiaomi also notes that physical objects placed in between the charging pile and the device do not reduce the charging efficiency.

Xiaomi says that it is looking to expand the technology to smartwatches, wristbands, and other wearables, as well as smart home speakers, desk lamps, and more in the future. It is unclear how close Xiaomi is to bringing its Mi Air Charge Technology and charging pile to the consumer market, but today’s reveal may suggest that it is sooner rather than later.

The announcement indicates that progress on remote wireless charging technology within the industry is steadily developing. Several years ago, Apple was rumored to be partnering with Energous to deliver its own remote wireless charging solution. Apple is still believed to be researching new wireless charging technologies, and with the advent of MagSafe on iPhone 12 models, the company is clearly interested in new ways to power devices.
