OPPO is the latest OEM with an over-the-air charging technology demo
Wireless charging is currently touted to evolve into a purer, more accurate form of this term in the future. Also known as remote or over-the-air charging, it is based on "beaming" power in forms such as millimeter-wave energy to a receiver on a given mobile device to fill its battery.
Xiaomi has claimed to demonstrate its prototype remote-charging system, called Mi Air Charge, in the works, in a concept video shortly followed by one from Motorola showing its competing One Hyper standard off. Now, OPPO has jumped on this bandwagon with one of its own.
It has shared its own clip of what is depicted as a phone using a form of wireless charging that kept working even when the (completely unconnected) device in question was lifted off a surface. Then again, this video - released as a teaser for OPPO's MWC Shanghai 2021 showcase, does not mention any specs for this apparent new breakthrough.
This technology - called Wireless Air Charging by OPPO - is particularly interesting as it is depicted as built into the X 2021: the OEM's slidable phone concept. Whether the truly wireless charging system is to be built into all of its units should it hit the market soon is unknown; nevertheless, it brings a little more interest to what might turn out to be vaporware (or tremendously impractical, at the least) in the end.
In any case, OPPO might release more details on its form of remote charging as MWC Shanghai progresses over the next few days. Meanwhile, the OEM also intends to bring its fastest 125W wired charging system to the show, as well as its 5G CPE product and the Reno5 smartphone series.
