The dream of wireless charging in the middle of the air teased with rollable Oppo X



Oppo has teased a new wireless charging solution that works when a phone is up to 10 cm (3.9 inches) away from a charging plate. The company has demonstrated its wireless charging technology in a 30-second clip on the Weibo page to coincide with MWC Shanghai. The clip shows the rollable concept phone Oppo X 2021, announced in November, and is charged over the pad, even when held at an angle. The technology offers charging speeds of up to 7.5 W, says Oppo.

The Chinese manufacturer is the latest to announce a truly wireless charging system, after Xiaomi and Motorola’s peas from earlier this year. Back in January, Xiaomi announced the Mi Air Charge Technology, which they say can charge multiple devices at 5W “within a radius of several meters.”

; The next day, XDA developers reported a demonstration from Motorola that showed that one of the phones is charging 100 cm (40 inches) from a charger.

At 10 cm, the range of Oppos technology is more limited than Xiaomi’s competitor, Android authority notes. The video’s presenter makes a very conscious effort to keep the phone directly over the charging mat. However, the charging displayed works even when the phone is slightly tilted over the wireless charger and while playing a video.

Differences like this are academic just since none of these technologies are released in commercial products. Xiaomi has confirmed that the technology will not be ready for release this year, and the mobile phone that Oppo used for the demonstration does not have an official release date.

In addition to developing wireless chargers that work over longer distances, manufacturers are also working to make standard wireless charging faster. Xiaomi is developing an 80W wireless charging solution, which it announced just months after Oppo unveiled its own 65W wireless charging technology.

Update February 23, 06:53 ET: Updated with the official name of the charging solution and more details.
