29th Jan, 2021 old smartphone manufacturer Motorola released a new charging technology: Air Wireless Charging.
This technology working principle is the same with now wireless charging, just send electromagnetic wave by launcher to one direction, then QI enabled cellphones receive the electromagnetic wave and transfer it into electrisity to charge cellphone. Unlike introditional 6-8mm distance limit, this new technoloy could wirelessly charge your cellphone over 1m or much more, its output is only have 5W, much slow than now wireless charging in the market.
Recently famous smartcellphone manufacturer Xiaomi also pushed their own air wireless charging, they called it Mi Air Charge, the same working principle and output, but what is improvement for Mi Air Charge is that the cellphone still could be air charged cellphone even there has some objects in front of cellphone, no need to remove the object, your cellphone still could be charged, what is a amazing technology !
What are the advantages for Air Wireless Charging:
- Real wirelessly charging for cellphone, not limited by charging distance.
- Avoid extra heat produced by charging demaging cellphone and charger.
- Much more convenient charging method without bring any extra cable and adapter. You can charge cellphone every where in charging area.
- This technology also could be used to charge for LoT devices in the future. There you never need to prepare so many sockets for them, only a charging launcher is enough, brief and convenient.
What are the limits of Air Wireless Charging:
- For now air wireless charging technology, its 5W wireless charging output is too low. As now most smartcellphones battery capacity is over 4000mAh, charging by 5W may will take too long time. Your charging speed may not keep up with the speed of power consumption. Like troditional wireless charging technology, i think its output maybe increase later in the future.
- Wireless charging launcher will produce much electromagnetic radiation when it works, we need to keep a lower electromagnetic radiation to ensure cellphone user safety. Improving charging efficiency and maintaining low electromagnetic radiation are the core issues that mobile phone manufacturers need to solve.
- If need charge cellphone by air wireless, the charger launcher need to release electromagnetic wave to one direction. The cellphone must be in this direction at the same time, so if there could be charge in a big range, the launcher releasing issues need to be solved later as well.
- The charging launcher and cellphones maybe very expensive at beginning of sales.
- This technology will take a long time for cellphone manufacturer to use it in their new launch cellphones.
Hoping we could enjoy this air wireless charging as soon as possible !
