MWC Shanghai is officially underway and Oppo used the event to show out a prototype Air Charger working in tandem with its Oppo X 2021 rollable concept. The short 30-second video shows the phone charging at all times from laying flat on the surface to being at an arm’s length away.
There’s not much detail as to how Oppo’s implementation works but well-known tipster Digital Chat Station claims Oppo’s air charging speeds can reach up to 7.5W speeds.
Digital Chat Station clarification
Back on April 1, Oppo teased a similar air charging tech called FreeVOOC. That implementation was touted of achieving stable charging power of 5-10W within 10 meters and relied on special embedded coils in the phone itself. It remains to be seen how the new implementation works and when we’ll see it in a commercially available form.
Xiaomi is another maker that is working on air charging and even showcased its development last month. Mi Air Charge relies on a large cube transmitter that beams up to 5W charges to compatible phones with built-in beacon antennas and receivers up to several meters away.
