MI Air Charging Technology – Is It Reality?

Mi Air Charging Technology 

Xiaomi has been one of the few phone companies setting the pace in terms of new technology. Today, it has taken it to another level with its Mi Air Charge Technology which allows you to charge multiple devices simultaneously without any cables or a wireless charging stand.

Working of the Mi Air charging technology: – 
  • The company has shared some details on its new Mi Air Charge technology on its official video. According to the company, this technology is capable of delivering 5W of power to many devices over a distance of a couple of meters from the “self-developed isolated charging pile”. This charging pile has 5 phase interference antennas to accurately determine the position of your devices. This helps in better connectivity with the MI Air charging station. 
  • After determining the position, a phase control array composed of 144 antennas directionally transmits millimetre-waves through beamforming. The receiving device has a miniaturized antenna array with a built-in “beacon antenna” and “receiving antenna array”. The former determines the position information. While the latter is a 14-antenna array which converts the millimetre-wave signals into electrical energy through the rectifier circuit. 

Concerns raised by the users: – 
  • Though the company has clarified that Mi Air Charge is just a tech demo at this stage. However, it’s not clear if the company will be able to overcome the implementational and structural marketing problems faced by other vendors which have shown off the no-contact wireless charging prototypes. Moreover, there are health concerns and there’s no doubt that if this technology ever makes it to market. It’ll be heavily inspected by regulatory authorities.
Final Verdict: – 
  • Xiaomi plans to add its Mi Air Charge Technology to its wearable devices such as smartwatches and fitness trackers in the future. It is also expected that it will be able to power other small devices in the homes such as speakers and desk lamps. However, the ultimate goal is to eliminate the need for wires which have become a concern in most households.
