Third wireless charging system boasts multiple device charging
The Alliance for Wireless Power (A4WP) has launched a new brand for devices that adhere to its certification program. The "Rezence" logo will be applied to devices that are compatible with a third wireless charging system that relies on the principles of magnetic resonance to transfer power, something that offers a number of advantages over existing wireless power systems.
By using magnetic resonance, the Rezence system lets multiple devices with different power requirements charge from the same charging mat simultaneously. The system is also claimed to work when other metallic items are nearby, and even through thin obstructions such as fabric or paper. Current wireless power systems don't offer these, but the groups behind them are already looking at how to incorporate Rezence's advantages into their own offerings.
While A4WP is slower in announcing Rezence than the Wireless Power Consortium and the Power Matters Alliance with Qi and Power 2.0 respectively, it firmly believes adoption of its own wireless power system will be much faster, thanks to these advantages. "We are already here with the future, and those other groups are a ways away," A4WP marketing chairman Jeff Gordon told The Verge.
The group will be showcasing devices using Rezence charging at CES in January, and hopes for the first devices loaded with Rezence to launch early next year. While the group did not advise what devices will offer it, the fact that the membership includes 70 companies, including a number of major manufacturers that are involved in all three wireless charging groups, suggests that a variety of devices will be on show, with smartphones being extremely likely to make an appearance.
