APC's Mobile Power Pack delivers juice via USB
Add the Mobile Power Pack from APC to the growing list of accessories able to provide your portable gadgets with precious extra hours of runtime. Promising up to 55 more hours of juice for your iPod nano or eight to ten hours for your Treo, the MPP UPB10 sports a high-capacity, user-replaceable lithium polymer battery that can power and charge nearly any device with a USB or mini-USB jack. If you don't have the time/inclination to build your own solution, this may be seventy bucks well spent.

















I'll wait until something like this shows up on woot for probably $40 instead of the $70. I'm still not sure how this is such a good advantage. Anywhere I could leave this black box I probably have a laptop I could plug in and charge my iPod.
10Wh is kinda pathetic for $70.
Yes, but can I use it to charge my /other/ APC Mobile Power Pack?
