The Alliance for Wireless Power changed its branding last year by focusing its wireless charging efforts under the Rezence banner. The consortium today announced plans to expand beyond smartphones by adding compatibility to tablets, PCs, and peripheral items. The Rezence charging standard has been updated to support to 50 watts of charging multiple devices. Increasing to that higher wattage, compared to 10 to 15 watts typically seen when charging smartphones, it's possible to recharge larger consumer devices. The need for the boost is obvious. While an above average smartphone battery might have a capacity of 3,000 mAh or higher, even run of the mill tablets have 5,000 mAh batteries. Pumping out more power will make it possible to recharge a tablet and a phone on the same pad.

Rezence is one of several competing standards to grow wireless charging. Though there are some plans for limited interoperability between Rezence and the Power Matters Alliance PMA, there's still stiff competition with Qi to become a real standard. The competition between all these factions has proved detrimental to consumers because it has created cases where companies favor one standard over the other, so the phone capable of charging in one location may not be able to charge at another venue. Feedback from carriers has also caused some phones to remove wireless charging altogether, such as AT&T removing Qi from phones from Nokia and LG.

Increasing its diversity of devices supported is definitely one way to help improve the A4WP's aim to make Rezence the more popular choice. To that end, the group has added Dell, Fujitsu, Foxconn, Lenovo, Logitech, and Panasonic as members.
