Mobile World Congress MWC 2021 kicked off in Shanghai with the theme “Harmony and Symbiosis”. At the exhibition, OPPO and industry partners held a flash charging technology ecological communication meeting, showing the ecological layout of multiple scenarios. Among them, OPPO’s core competence flash charging technology debuted as the protagonist, and at the same time, there is currently a heated discussion on air-space wireless charging technology.

It is understood that OPPO air-space wireless charging technology utilizes two technical support of “adaptive matching technology” and “magnetic field equalization technology”, and is based on a new upgrade of the OPPO X 2021 roll axis concept machine, further expanding the user’s freedom of charging scenarios. Come true wireless charging without contact, disconnected from the charging cable and charging pad.
There is no need for air charging piles and millimeter wave transmitters. The current OPPO air charging technology can support 7.5W charging power within 10 cm. At the same time, it has low requirements for the angle and placement of the device, and has a certain degree of usability.

Last year, Xiaomi and Motorola both announced their own space charging technology.
First of all, Xiaomi’s air-to-air charging technology is based on Xiaomi’s self-developed air-to-air charging pile. With 5 built-in phase interference antennas, the mobile phone can be positioned in millisecond space and accurately detect the location of the mobile phone.
At the same time, the phase control array composed of 144 antennas transmits millimeter waves to the mobile phone through beamforming. The mobile phone receives the micro beacon antenna, which can realize 5W long-distance charging within a few meters.
Secondly, Motorola relies on the desktop millimeter wave transmitter to achieve directional charging with a range of 80-100 cm. It is worth noting that if the transmitter is blocked by hand, charging will stop immediately. Motorola subsequently updated the video again. When foreign objects are blocked in the video, it does not affect the charging in the air. It supports charging while playing.
