Oppo has a rollable phone with true wireless charging

Chinese smartphone maker Oppo has always been at the forefront when it comes to charging technology, and the company is proving it once again with a new smartphone that charges completely wirelessly.

The charging tech is not without limitations. The Oppo X 2021 smartphone, presented during the Mobile World Congress Shanghai, which kicked off on Tuesday, can charge up to 10 centimetres away from a charging mat. This is achieved with magnetic resonance tech which can deliver up to 7.5W of power to the device. No cable or charging stand is required, Oppo says.
