We've seen plenty of mobile chargers
in our day, but the Xantrex PowerSource Mobile 100 claims to be the first to power multiple devices simultaneously at different voltage and power levels. The $130 unit includes a pair of USB ports and an AC plug, making it a quite convenient way to power your phone, iPod and laptop all at once. Xantrex promises plenty of power, too: 2 hours for laptops, 12 hours for portable game systems, and a spankin' 72 hours for the iPod nano. Of course, the lithium-ion based PowerSource is a decent bit heftier than a spare laptop or phone battery, but if gadget diversity is your game it doesn't seem you can go far wrong here.
