Works great. Perfect product for the daily business commute, or day trip. Easy to carry with lots of pockets. The battery dies in about 6 hours if you are inside. Well worth the time of charging your phone and other items. Once you go outside and the sun light is on the panels it charges right back up. It took about 2 hour to charge to full. This is a good item for the money.
I would recommend this for anyone interested in a solar backpack.

Nice hunt. Keep hunting.
