Apparently Xiaomi isn’t the only mobile phone company working on over-the-air wireless charging. At MWC Shanghai 2021 earlier today, Oppo unveiled its own take on the futuristic technology, which is aptly dubbed “Wireless Air Charging” for now. The company’s demo – both on the stand and in the official video – featured a Oppo X 2021 Roll-up concept phone placed on a wireless charger, and even when lifted slightly while tilted slightly in different directions, the device was still able to charge.
According to Oppo, its Wireless Air Charging technology uses magnetic resonance to deliver up to 7.5W of power, and it kicks in when the device is within 10cm of the charging mat. It may not sound as impressive as Xiaomi’s “Mi Air Charge” which, using RF millimeter waves, can deliver 5W of power in any direction for several meters, although it requires a lot of charging station. larger (and probably more expensive) – much like the router for Energetic ‘WattUp system.
Magnetic resonance and RF wireless charging are of course not new. Members of AirFuel Alliance have been pushing these standards for nearly a decade, and we handle of demos in person too. But for various reasons, the industry as a whole is yet to be convinced of what is supposed to be the next evolution in wireless charging. For now, we’re stuck with wireless inductive charging, until Samsung and Apple make a call – much like they finally popularized Qi.
Meanwhile, Oppo has found a few new partners to help expand its VOOC fast charging ecosystem (which can also be fully utilized by recent devices from OnePlus and True me, of course). One of the latest recruits is Chinese company FAW-Volkswagen, which will integrate Oppo’s mobile charging technology into its locally manufactured vehicles. anchor, a brand known for its mobile accessories, today launched its first VOOC compatible charger and its first portable battery, both of which offer 20W VOOC and 18W USB-PD charging.
Semiconductor company NXP has also become one of over 40 VOOC licensees, with its MWCT2013A car charger platform supporting the existing 40W AirVOOC (as featured on Oppo Evangelion Phone) as well as Qi wireless charging standards. Apparently, there’s a good chance this solution will end up in an FAW-Volkswagen car, and who knows, maybe car makers in other countries will join in the fun as well.
