A4WP announces wireless charging up to 50 watts for the first time for mobile devices

Wireless charging is gradually becoming one of the most important elements of the smartphone ecosystem. The Alliance for Wireless Power (A4WP) has introduced multi device wireless charging solution for mobile devices at the Computex. The company announced continued momentum on the expansion of the organizations Rezence-based wireless charging capabilities, becoming the first to deliver a specification for multi-device wireless charging up to 50 watts for mobile devices like laptop, smartphones and tablets.


The Rezence brand is backed by hundreds of consumer device makers and chip companies. Dell, Fujitsu, Hon Hoi (Foxconn), Lenovo, Logitech and Panasonic have joined the A4WP with the aim of integrating wireless charging into a wide range of consumer electronics devices. A4WP claims that its Rezence technology delivers wireless power solutions in the 1-50W range whereas other wireless charging solutions deliver power in the 10-15 watt range. The broad industry support and continued momentum confirms the overall interest and investment in Rezence technology scalability, flexibility and consumer benefits. Moreover, Rezence also supports wireless charging of multiple devices with differing power requirements on the same charging surface which is a unique to magnetic resonance technologies.

Kamil Grajski, President, Alliance for Wireless Power in an official release said, “As highlighted by A4WP member companies at Computex, wireless power is about more than charging a phone on a pad. Flexibility, in both power and placement, are key to expanding wireless charging beyond a niche. A4WP member companies are driving the expansion of the Rezence specification to enable new usage models. Extending Rezence to include laptops, tablets and peripherals is a necessary step towards a wire-free and universal charging experience for everyone”

A4WP members including Intel, Broadcom, MediaTek, PowerWoW and iCirround will showcase a variety of Rezence-based demonstrations at Computex 2014, in Taipei, Taiwan, 3-7 June, 2014. Last week, Broadcom released multi-standard wireless charging chipset for smartphones.
