My daughter gave me a Duracell Powermat for Christmas and I'm loving it so much I bought a second one for my New York office. The system consists of a sleek base unit that can accommodate two devices, a case for my Samsung Galaxy S3, and a portable battery unit that can charge a fading phone away from the base. This is cordless charging, the same inductive technology used to recharge electric toothbrushes. I first saw it demonstrated in 2009 at Qualcomm, but it was a bit clunky and didn't seem all that interesting at the time.
But in practice the system is awesome with a couple irritations. After fitting the case over the phone and plugging it's male connector into the phone's female micro-USB port (tight fit, which makes changing cases a bit of a hassle -- more on that in a second) the phone can be placed on the charging base where it magnetically slips into the proper position with an audible confirmation that charging has started. I set the phone to go into "bedside" mode when its docked on the Powermat. Only two phones are supported -- the Galaxy and the iPhone 4s -- but the iPhone 5 case is expected sometime soon. The base units come in three, two and single device configurations. I thought the spare battery brick was a nice-to-have, not a need-to-have, but on a recent vacation it was pressed into use.
The hard plastic case isn't as rugged as an Otterbox and has to be removed if I want to dock the phone in the car cradle. I imagine Duracell has a car unit in the works, but for now I have to peel off the Duracell case to use the phone in the car for the usual GPS/handsfree/Audible/music stuff.
Duracell is pushing the technology hard, painting a picture where charging bases will be available in coffee shops, nightclubs, airport lounges, stadiums, etc.. and apparently truly wireless charging is over the horizon.
Here's the obligatory YouTube vision of Millenial bliss:
The double-device mat is $90 at Amazon and includes the portable battery pack and a case for a single phone.. A one-device mat is $32.
