Jumpbox

This is hands-down the best emergency battery that we've seen. Imagine being able to jumpstart your car as well as power/charge any device that you have. Jumpbox does just that... and it maintains its own charge for up to 2 years.

 

From the manufacturer:

StarkPower's "JumpBox" Lithium Ion battery is the ultimate in weight versus power technology to jump start 12V vehicles (SUV, TRUCKS, BOATS, RV, PowerSport).
