WattUp Distance Wireless Charging Coming To Major-Brand Phone
Energous has revealed that a "tier 1" consumer electronics company has agreed to implement WattUp wireless charging technology in a number of consumer products, including a phone. WattUp is an RF-based wireless charging technology that can be implemented in a number of ways, including transmitters that can send power wirelessly up to 15 feet, using a large array of antennas and beam-forming technology to send focused energy in the 5.8 GHz radio band. Smaller transmitters using fewer antennas can be pocket-sized, but only send power about an inch. In both cases, typical power sent is about a half a watt, enough to charge a wearable, or trickle-charge a phone, although higher power is possible with more antennas and shorter distances. Energous representative Gordon Bell gave an example of a computer monitor with the company's transmitters built into the bezel, that could wirelessly charge any wearable device on the user's desk, or trickle-charge a phone. A wearable device might ship with a small WattUp charger in the form of a USB stick, eliminating the need for a wired charger and wired connector. WattUp receiver antennas are smaller than wireless charging antennas from competitors such as Qi. Energous expects this tier-1 manufacturer to release WattUp-enabled products by the end of this year or early next year. Further details about products and configurations has yet to be announced.
