Dell joins alliance that hopes to bring wireless charging to laptops

All around the world, we see computer users in coffee shops, at airports, and in many other public places wrestling with power cords and those huge adapters that keep their laptops charged. Wouldn’t it be so much easier if wireless charging for these devices finally came into its own? It could happen soon, with major computer manufacturer Dell hopping on the wireless charging bandwagon by becoming the first PC maker to back The Alliance for Wireless Power. The Alliance for Wireless Power calls for a standard for wireless charging of devices that need anywhere from 20 to 50 watts of power, such as laptops. The concept is to use something called Rezence, which uses magnetic resonance to charge multiple laptops and other devices at the same time, without the need for cords or docks.
