Ultrasonic Wireless Charging Technology SonicPower Passes Safety Certification: Powering Multiple Devices Simultaneously Within 5-Meter Range
US startup Ubeam's SonicPower ultrasonic wireless charging system passes UL safety certification, simultaneously charging up to 8 devices within 5 meters at 15 watts total output.
US wireless charging startup Ubeam announced on July 20 that its SonicPower ultrasonic wireless charging system has passed UL safety certification, becoming the first commercially approved ultrasonic wireless charging product. The system converts electrical energy into acoustic beams through ultrasonic transducers, directionally transmitting power to piezoelectric receivers on devices within a 5-meter range, simultaneously charging up to 8 devices with total output power of 15 watts.
Ubeam CEO Molly Blocher stated: "Electromagnetic wireless charging requires devices to sit on charging pads. Acoustic charging allows devices to charge continuously while moving freely around the room." The first smartphones with SonicPower receiver modules are expected to launch in Q2 2030.
