Juicebox Portable Power Box

During my morning browsing I came across the Juicebox portable battery backup box. Built into a USGI surplus ammo can, the manufacturer claims that on a single charge it can:

• Charge a typical laptop six times
• Charge a Smart Phone 50 times
• Charge a Cell Phone 80 times
• Run an I-Pad® for nearly 100 hours
• Run a portable radio for weeks
• Run a GPS for 140 hours
• Run a desktop fan for 20 hours
• Light up a campsite for several nights

It's a neat solution for providing power in the field or in the event of an outage. Even if you don't want to buy one from them, it can serve as inspiration for a homebrew setup. See, for example, ChinoUSMC's emergency communications ham radio and backup power setup, here.
