Energous claims to have a solution to the often imperfect practice of wirelessly charging our mobile devices. The company’s WattUp technology — winner of this year’s Best Innovation from Engadget’s Best of CES — can charge up to 12 gadgets at once within a radius of 15 feet (the closer your device is to the $300 transmitter, the faster the charge). According to The Verge, “Energous’ vision is that your phone, wearables, and other devices will slowly charge throughout the day, preventing you from ever having to actually plug it in or worry about power level.” The tech may one day appear in smartphones and wireless speakers, but in the short term you’ll need to place your phone in a WattUp battery pack.
