Battery maker Duracell has recently announced a charging system called myGrid that will charge cellphones and other devices placed on its surface. Similar in concept and execution to the WildCharge energy plate, the device can be ordered as a kit that is compatible with Apple's iPods, the iPod touch and the iPhone, as well as a number of handsets from Nokia, Motorola and RIM's BlackBerry handsets, though each kit requires a charging sleeve.

Duracell says rechargeable portable audio players can also be charged, though does not elaborate on applications. The mat can also reportedly recognize when water, metal or a hand is resting on its surface and automatically shuts off.

While a price is not yet announced, the device is due for a release in October.
