iPods are great devices to listen to, but they fall short in the battery life department when it comes to viewing videos. The Macally IP-A480 external li-ion battery aims to solve this problem, offering an additional 6 to 8 hours of power for your iPod. It is compatible with all Dock Connector iPods except for the 3G iPod. The battery level is indicated by 3 lights located at the front, while the fourth light depicts the charging status. Just press a button to check the current levels. There is an on-off button at the bottom for you to control the power flow. This battery is recharged via a computer’s USB port.
