This is a smaller package to a total solar hiking solution I bought composed of this and the Sherpa 50 Adventure kit. This serves a daypack function and keeps my iphone charged while it's in GPS mode ont he hikes. Paired with the Nomad 13 in my Sherpa kit, this gives unlimited juice to my iphone 4S and other USB devices.
Pros: quick charging, light weight, can use eneloops
