Xiaomi introduces true wireless charging from across a room

(Web Desk) - Xiaomi has introduced its latest wireless charging tech - Mi Air Charge - which can charge multiple devices simultaneously. It will also be able to recharge a smartphone that’s being used while walking around or even when something’s in the way.

The transmitter of the charge can provide a 5W charge wirelessly to a smartphone and has nothing to do with the Qi standard. The smartphones need to be outfitted with a “miniaturized antenna array with built-in ‘beacon antenna’ and ‘receiving antenna array’.” The smartphone has 14 antennas to convert a millimeter wave signal that’s emitted by the charging pile. The signal is converted into electric energy through a rectifier circuit.

In its current state, Xiaomi’s remote charging technology can charge multiple devices with a 5W current within a radius of “several meters”. Xiaomi claims that physical objects don’t reduce the charging efficiency.

This tech would be eventually compatible with smartwatches, fitness bands, and other wearables as well.
