Xiaomi Air Charge Technology Boost up your device Wirelessly


A revolutionary move by Xiaomi, the Chinese tech giant has released a new charger called “Mi Air Charge Technology,”. This charger allows devices to charge wirelessly without feeling the need to plugging the phone and saves you from sitting near a wall for a power supply. The “true wireless charging” device from Mi Air Charge Technology is free of cables or stands. Devices charge 5W of power remotely with advanced spatial positioning and beamforming transmission of energy. Multiple devices without cables or charging pads/stands can be charged remotely With Mi Air Charge.

In device charging technology, Xiaomi has taken advanced moves. Recently, the company unveiled an 80W wireless traditional charger, which charges a phone completely in less than 20 minutes. Likewise, the upcoming Mi 11 Pro will allow a 120W wired charger as per rumors. The Mi Air Charge is a new product category with remarkable features. The patented technology is presented in a short clip by Xiaomi.

How does it work?

The core technology behind Xiamoi’s remote charging phenomenon lies in space positioning and energy transmission. Sounds too complicated, right? Let’s take it this way, Xiaomi has a self-developed isolated charging pile, more like a set of interference antennas. Which can accurately detect the location of your smartphone.

If your smartphone comes in contact with the said charging pile, it transmits millimeter wide waves through beamforming. Beamforming essentially allows an antenna to transmit a wireless signal from one location to a specific endpoint (in this case your device) instead of aimlessly and inefficiently around an area.

So we know how the charging pile emits waves, but is there anything on the smartphone side? Xiaomi has developed an antenna array comprising a ‘beacon antenna’ and ‘receiving antennas.’ These antennas convert the millimeter-wave signal emitted by the charging pile into electric energy through the rectifier circuit, which is basically turning the sci-fi charging experience into reality.
