The main convenience offered is no longer having to plug a cable into the device that needs charging, but you still need to position each device accurately on a charging pad and a bigger or multiple pads are required for charging more devices.
Shares of tech companies were more or less flat as fears about demand for Apple's latest iPhone persisted. The FCC certification of Energous' power-at-a-distance wireless charging transmitter is a major market milestone.
Wireless Charging provides a convenient, safe, and reliable way to charge and power millions of electrical devices at home, in the workplace and in industry. The transmitter converts electricity into radio frequencies, then beams the energy to nearby devices outfitted with a corresponding receiver.
The wireless standard hasn't yet been specified by the company.
While Energous' WattUp transmitter has FCC approval, it isn't ready for retail yet. This is the first FCC certification for power-at-a-distance wireless charging under Part 18 of the FCC's rules. The company has not yet launched its system yet but instead intends on showcasing it at the CES 2018, which will be held mid-January in Las Vegas, Nevada. In theory, any device that has the receiver connected to will be able to use this technology. While companies like Energous may be able to ideal their own systems, these are all but destined to require bulky phone cases to function as a receiver for the near future until phonemakers are enthused enough about the tech to build it into phones directly. The new technology sends focused RF power to devices up to three feet away. Energous says that its product is the only one that can deliver both contact and non contact wireless charging.
Wireless charging devices are already available, but have to be in direct contact with the phone or other device they are recharging. If any wireless charging supported device goes below 100% charge and is within the range of WattUp, it will start charging that particular device.
