Powermat has a wireless charging solution that uses, you guessed it, a mat that you just place your gadgets on, and voila!, they’re charged up. It uses magnetic induction just like many of the other (promised) solutions. They have a wide range of products ranging from the small, folding to the large desktop variety. Apart from the added price, the only 2 drawbacks that I can see is the limited number of devices that they support, and that you need some kind of device adapter and/or support pre-built-in.
Devices: iPod, iPhone, Blackberry, Razr, GPS unit, handheld game, laptop computer. Not yet available, but expect $100 mats and $30 chargers.
