A4WP Amps Rezence Wireless Charging Spec Up To 50 Watts

TAIPEI, TAIWAN – The Alliance for Wireless Power (A4WP) formally announced an increase in the capability of the group’s Rezence wireless charging standard to 50 watts.

The increase, first revealed by A4WP member Intel at Computex 2014, here, expands the range of products capable of using Rezence technology to charge multiple devices wirelessly beyond smartphones to include laptops, tablets and other power-hungry consumer electronics.

To support “upcoming rapid product launches,” the publication and upgrade of the existing Baseline System Specification and certification program is expected by the end of 2014, the A4WP said.

In addition, Fujitsu, Hon Hoi (Foxconn), Lenovo, Logitech and Panasonic were announced as new members of the alliance. Member companies now top 100 for the first time.

An A4WP statement claimed wireless charging technologies operating at frequencies lower than 6.78MHz are subject to technical limitations that make the move to higher power difficult to implement in a manner acceptable to consumers. “While the organizations associated with these technologies are only now discussing the delivery of power in the 10- to 15-watt range, Rezence technology now delivers wireless power solutions in the 1- to 50-watt range that support multi-device charging while preserving freedom of placement in horizontal and vertical dimensions for a true drop and go user experience.”

A4WP members including Intel, Broadcom, MediaTek, PowerWow and iCirround showcased Rezence-based products at Computex.
