Callpod, maker of the six-way Chargepod charging system, has just announced the Fueltank, a portable battery that can recharge two gadgets simultaneously. It uses the same adapters as the Chargepod, which means it's very customizable, and should support just about all the devices its older, more plugged-in brother can. It'll retail soon for a not-too-bad price of $59. [Callpod]
