First Look: Macally IP-A481 External Li-ion Battery for iPod
Compatible: iPod 4G, 5G, nano, mini, shuffle
Available in black, this new external Lithium-Ion battery pack is packaged as a way to add "approx. 6-8 hrs" of run time to an iPod - model not specified, but bear in mind that newer iPods are more efficient than old ones, and flash-based iPods (nanos, shuffles) are more efficient than hard drive-based ones. It will work with all Dock Connector iPods save the 3G iPod, assuming you provide a Dock Connector-to-USB cable (not supplied). Three lights on its front indicate battery level, while a fourth indicates charging status, and a button is used to check the current levels. An on-off switch on the bottom lets power flow to your connected iPod, or turns it off. Despite the presence of a 5-volt DC port on the bottom, there's no wall charger in the box; the pack includes a USB-to-USB cable, and you're supposed to recharge using a computer's USB port. A fabric carrying case for the battery and cable is included.
