At CES at the beginning of the year, Motorola demonstrated a new wireless charging technology-different from the typical Qi charger, it allows mobile phones to be 1 meter away (3.3 feet). It can handle two devices at the same time. The company has developed the second generation of this technology with greatly improved functions.
Now, the cell phone and the charger can be charged in clean air up to 3 meters (10 feet) away. This is a large charger equipped with a phased array and up to 1,600 antennas. The arc covered by the charger exceeds 100º, so even if the phone is put aside, it can still supply power to the phone.
Due to the wider coverage, the new charger can handle up to four mobile phones at the same time, which is twice as much as the original device can manage. The charger can even handle some obstacles between it and the phone.
This means that the phone can be charged in your hand or pocket. The charger can detect your body and aim the beam away from it so that it only hits the phone.
Last year we saw some competing technologies, such as Xiaomi’s Xiaomi Air Charge, It uses 144 antenna arrays to provide 5W power to mobile phones “within a few meters”. This can handle two mobile phones at the same time.And OPPO Air charging Technology, promises up to 7.5W, although it can only work within a distance of 10 cm (4 inches) and does not seem to be able to handle multiple devices.
