Goal Zero Nomad 7 Adventure kit...best solar charging option at a decent price. It's efficient, powerful, and charges 4 AA eneloops, no prob. Got it wet a few times, still workin'. Comes with a car plug adapter as well. Last time I went camping, I brought it, and I was charging in laws Iphones, there r/c air pump, two-way radios...even topped off my next "Man I'm glad I got that!"
Portable power pack. Can jump start a car, has USB ports, two car ports. I ran my base scanner off it for 8 eight hours, and it still had plenty of juice. Great for topping off my rc's for lights, or my two way radios during an extended power outage.
These are just two of the few items that are worth their weight in gold when they are needed.
