Motorolas over the air Space Charging station shown to charge four phones at once from up to three meters away.

FULL STORY ======================================================================

Motorola showed off its over-the-air (OTA) wireless Space Charging tech in an unlisted and supposed demo video and while it still seems a ways off from being production-ready, the company demonstrated that one of its charging stations can remotely juice up four phones at once.

The station itself (or the prototype shown in the video, at least) looks like a WiFi router a gray plastic rectangle on a stand with blinking lights on
the side and a Motorola logo emblazoned in the middle.

The video shows the station charging up to four phones (what appear to be Motorola Edge flagship devices, presumably with wireless charging coils) at a distance of one meter, and shows the station recharging a phone at up to
three meters. Whether it can juice up multiple devices at that range is unclear, and it seems to have a maximum charging rate of 5W according to Android Central , which first found the video.

Thats a paltry rate compared to other wireless chargers on the market, which exceed 15W in even affordable models; of course, those only charge if devices are placed directly over the charger. Its much easier, if slower, to have one station in the center of a room recharge a phone in a pocket or in hand. Analysis: over the air charging, the next frontier?

Most flagship phones pack wireless charging these days, but as previously mentioned, the wireless part only means there isnt a wire between the phone and charger it still requires extremely close proximity to transfer power.

The advantage for over the air charging is obvious, but its unclear how close we are to getting a fully-functioning version, let alone phones that are compatible if they need more than stock wireless charging cables. Not many phonemakers seem to be ahead with over the air charging, however only Motorola, Xiaomi, and Oppo have claimed theyre working on the tech.

Motorola is working with the company GuRu to develop its Space Charging tech, using radio waves to recharge devices at a distance, while Xiaomis Mi Air Charge is an in-house solution with five phase interference antennas to
locate and distantly charge phones. Oppos solution opts for magnetic
resonance to juice up phones, but has less range than Xiaomis option, at
least for now.

All this tech still seems far from ready to hit the market, but at least theyre on the way which is more than we can say for a possible Samsung OTA option, which has only shown up in a patent . Wireless charging on
smartphones : what could the next 10 years bring?
