As much as you love your iPod nano, it's going to run out of power during that flight to Australia. So will your BlackBerry. And your Dell notebook. If you want to keep using them — all of them — then simple portable power isn't enough. You need the versatility of the Xantrex Xpower PowerSource Mobile 100. Yeah, it's a ridiculously overnamed device, but the idea is pretty good: a portable power supply that can juice up a bunch of separate gadgets simultaneously. It has a pair of USB ports and a regular AC outlet, able to power three of your toys even if they demand different voltages or power levels. Available now for $130, the PowerSource can store reserves that'll get you an extra 2 hours for your laptop, 3 hours for a portable DVD player, and no less than 72 hours for your nano — enough for your return flight, too. Though you might want to save a little in case you encounter any… uh, unscheduled stopovers. — Peter Pachal
