The Macally PowerLink can do three things, it can sync between your computer and your iPod/iPhone, charge your iPod/iPhone, and hold up to 2GB of memory from your computer. This seems to be perfect for the person who constantly needs a computer and a genius apple device nearby. The battery inside the PowerLink is a rechargeable Lithium Ion, so it serves well as an emergency charge for your iPod or iPhone. The level of charge is displayed on the top of the PowerLink, and also has an On/Off switch that shows you in a flash what is going on.
