Earlier this month at Mobile World Congress in Barcelona, we had the chance to take a look at the infamous Powermat. Powermat is a wireless charging system and an aspirant for the hottest gadget of this year. Instead of having a spaghetti of cables for charging your various gadgets, Powermat confines all this mess into one simple and revolutionary mat. All you need to do is place your phone or device on the mat and it begins charging instantly. So how does this wireless charging technology work? Well, the whole system consist out of one mat, that is available in different sizes allowing you to charge up to three devices simultaneously, and a receiver which is attached to your device of choice. The Powermat X1, X2 and X3 will be available in Summer 2010 for a retail price of $29,99, $44.99 and $59,99 retrospectively. The number of the mat, i.e. X# indicates the number of devices that the mat can charge. There are potable as well as home and office mats available which can be used as a very nifty hub.
