With the number of gadgets we carry around on a daily basis, it’s not uncommon for one of these electronic doo-hickeys to run out of juice at the most inopportune time. The Mobile Power Pack from APC isn’t the lightest or smallest solution imaginable, but it does provide a portable battery boost for all your USB-charging devices.

Say you’re going for an extended road trip on the Greyhound. You could take the low tech route and pick up a novel and read the hours away, but personally, I’d probably kill the time jamming to an MP3 player instead. When your iPod nano runs out of power, you can connect it to the MPP UPB10 for an extra 55 hours of head bobbing goodness. No boredom to ensue. For mobile professionals, the APC solution can give up to ten hours of power for your Treo.

Compatible with most USB or mini-USB devices, the MPP UPB10 should be available now for about $70.
