With more smartphones being sold than ever before, it's not surprising to see plenty of innovative chargers being designed for the battery-guzzlers. This "Juice" model not only charges phones, but AA and AAA batteries too.
On either side of the device is an "air holder," where batteries can be recharged, and there's also a USB port for charging other gadgets, like your iPhone, and the AC input for charging the actual device. While it's shown up on king of the concepts site Yanko Design, it's actually going on sale in Japan and Taiwan in the first half of 2010, and then the US after that. [Nobil via Yanko Design]
