Qualcomm Intros Wireless Charging Through Metal
Qualcomm today announced new technology that allows metallic handsets to charge wirelessly. Most wireless charging pads are tolerant of some metal in the charging field, but Qualcomm says it was able to boost the sensitivity enough, via Near Field Magnetic Resonance technology, to allow for wireless charging through metal handset enclosures. Qualcomm's WiPower is based on the A4WP's Rezence standard and can deliver up to 22 watts of power to charge handsets wirelessly. Rezence pads can handle several different devices, with varying charging requirements, at a time. Qualcomm did not say when it expects to see the metallic device charging technology reach consumer handsets.
