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. Basically, the idea is to create a world that is "always on, always connected" and always powered. Having a specific standard for wireless charging is important: it means that any device is charged wherever wireless charging is available. Imagine being at the coffee shop with a charging station, where your laptop stays powered all day while you sip on lattes and write the next great American novel. Or even better, imagine charging stations at the airport that don’t force you to stand in line just to use an electrical outlet. Having a standard means everyone wins: businesses and consumers.
Let’s face it, the idea of not having to lug power cords around with our laptops is one to get excited about. Unfortunately, a Rezence-powered device doesn't yet exist. We don’t really even have a lot of options for wirelessly charging our smaller devices (which is ridiculous when you think about it). However, now that Dell has jumped on board with The Alliance for Wireless Power, we may actually see some cord-free laptops and other devices in our near future. The only question left to ask is: why did it take so long?
