When wireless charging made its way to smartphones a couple of years ago, the world sighed in relief at the thought that at last we’re getting rid of at least one cord.
The Alliance for Wireless Power, which includes such big players as Dell, Fujitsu, Lenovo, Logitech and Panasonic, claims that the resonance charging model it has been working on has now 50 W of power. This is enough for charging laptops, tablets, and other devices that are not extremely power hungry. The jump from smartphones to laptops is quite noticeable, and we hope that Rezence, the wireless charging brand of this alliance, will get its products on the market in the not so distant future.
Peter Hortensius, chief technology officer, Lenovo, stated: “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. In evaluating the different wireless charging technologies, we determined that the A4WP system operating at 6.78 MHz best meets our customers’ needs because it delivers the power and convenience necessary to easily charge all your devices.”
Marcel Stolk, senior vice president, Logitech, detailed the advantages of a universal charging solution from the perspective of a manufacturer of various types of hardware: “Logitech makes consumer electronics that span the power gamut, including computer and mobile accessories, gaming and music products. Having a universal wireless charging solution that is both flexible and scalable is important as consumers buy more devices that require charging. Rezence is the logical fit to enable us to deliver a superior customer experience.”
Kamil Grajski, President, Alliance for Wireless Power, concluded that “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.”
I must admit that I like the idea of living in a world without wires, and I hope that Rezence’s solutions will be available soon. If the price is right, we might get to say goodbye to laptop and tablet chargers forever.
