Xiaomi has announced their new Mi Air Charge which allows you to charge your device without connecting the charger or wireless charging pad. So how does it work? The smartphone is needed to be fitted with an Antenna Array. The smartphone has 14 antennas that will convert millimeter-wave signals emitted by the charging pile. The signal will be converted into electric energy through a circuit rectifier.
Xiaomi’s Mi Air Charge can charge multiple devices simultaneously with a 5W current within a radius of several meters. Xiaomi is claiming that no physical object doesn’t disturb or reduce the charging efficiency.
