This is part of a total solar hiking solution I bought composed of this, a Guide 10 Plus (for smaller day trips), and 12V Alligator Clips. This supplies all my USB, 12v, and wall charging (for the most part, using the 110 inverter) power needs while hiking, using solar. Lightweight and powerful. Can't beat that for the price, trust me I've looked.
Pros: light weight for the power it generates, solar panel and Sherpa 50 output is some of the best in the business
