Alliance For Wireless Power Expands Rezence Initiative To 50 Watts To Include Tablets And Laptops

The promise of wireless charging isn't without its limitations. Two of the big ones are that it usually requires a pad of some sort, and it's limited to smaller devices. Not so with Rezence, the first standard to wirelessly charge higher power devices with spatial freedom. It's backed by the Alliance for Wireless Power (A4WP), which is comprised of companies like Dell, Fujitsu, Intel, Lenovo, Logitech, Panasonic, and many more.

A4WP announced today the expansion of its Rezence-based wireless charging capabilities, making it the first to deliver a specification for multi-device wireless charging up to 50 watts. That also expands the type of products that can use Rezence technology to include bigger devices like laptops, tablets, and other consumer electronics.


"The ability to easily wirelessly charge a laptop, smartphone, or accessory marks a powerful shift, untangling us from the wires that have become a part of our everyday lives," said Peter Hortensius, chief technology officer, Lenovo. "In evaluating the different wireless charging technologies, we determined that the A4WP system operating at 6.78MHz best meets our customers’ needs because it delivers the power and convenience necessary to easily charge all your devices."

According to A4WP, wireless charging technologies that operating at frequencies below 6.78MHz face technical limitations that make the move to higher power difficult to implement in a way that would be usable for consumers. Rezence isn't bound by those same limitations.

"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," said Kamil Grajski, President, Alliance for Wireless Power.
