Qualcomm Develops Rezence Wireless Charging Solution Tolerant of Metal Devices

Qualcomm, a founder of the Alliance for Wireless Power, said it engineered Rezence wireless charging for devices with metal exteriors. Using Qualcomm WiPower, it is the first announced technology to support wireless charging for metal devices, Qualcomm said Tuesday. Until now, it said, charging a device with a metal exterior has been incompatible with wireless charging technologies. "Building a wireless charging solution into devices with metal exteriors is a significant step for moving the entire industry forward" because device manufacturers are increasingly using metal alloys in product designs for better structural support and aesthetics, said Steve Pazol, general manager-wireless charging, Qualcomm. WiPower, along with other technologies that meet the Rezence standard, operate at a frequency more tolerant of metal objects that come within the charge field such as keys and coins, he said. WiPower added the ability to have the device itself made of metal while maintaining the ability to charge devices up to 22 watts at speeds equal to or faster than other charging technologies, said Pazol. WiPower allows wireless charging without the need for precise alignment or direct physical contact, while enabling simultaneous charging of multiple devices with different power requirements using Bluetooth Smart, said Qualcomm.
