Oppo wireless Air charge in its rollable phone – Oppo X 2021

Oppo has launched a new wireless charging solution that works when a phone is 10 cm (3.9 in) away from a charging pad. The company featured its wireless air charging technology in a 30-second clip on its Weibo page to coincide with MWC Shanghai.

The clip shows the Oppo X2021 rollable concept phone, announced in November with a rollable screen, charging above the pad even when held at an angle. Oppo states that the technology provides charging speeds of up to 7.5W. The company also introduced Oppo AR Glass 2021. The Oppo X2021 is equipped with a roll motor power-train, allowing two displays to be rolled.

Is it the best wireless air charger?

The company said that this charger also works on/off axis. You can charge a smartphone at a time without the help of a charging stand or cable. In November 2020, the company shared a video clip showing the rollable smartphone charging above the pad. Oppo technology offers charging speeds of up to 7.5 watts.

Even the wall will not stop charging

Back to January, Xiaomi announced Mi Air Charge Technology works on remote charging technology, in which the smartphone in your hand starts charging only a few feet away from the charger. The special thing about this charger is that there is a wall or some other obstruction in the middle of the charger, yet this technology works. Earlier, Motorola has also shown one of its smartphones by charging from a distance of 100cm (40 inches).

Oppo Air charge VS Mi air charge

It was able to charge devices within a radius of a few meters. Remote charging technology is capable of 5W remote charging for a single device. In additional, multiple devices can also be charged at the same time. These devices should have 5 watt charging support. However, the Oppo Air charge has capacity of 7.5W, that’s more, but one thing is that there are not much features compared to Mi Air charging technology.

Along with developing long-range wireless chargers, manufacturers are also working to speed up standard wireless charging. Xiaomi is developing an 80W wireless charging solution, which was announced a few months after Oppo revealed its 65W wireless charging technology.
