Customer Rating: Summary: Too weak to be helpful Comment: I took one of these on several backcountry mountaineering excursions in Colorado over the course of several months. In all but the strongest sunlight, it is too weak of a unit to satisfactorily charge any battery or appliance, and when it can, it takes many hours to do so. If the sky is anything other than crystal clear with direct sunlight hitting the panels, you could spend an entire day trying to trickle charge just one small camcorder battery. Yes, the previous reviewer had several units linked together, but I'm not prepared to have my backpack look like the International Space Station. Don't waste your money. Customer Rating: Summary: great electric power while hiking or camping in the boonies Comment: i have three of these to power my cell phone and rechargeable lantern while i go hiking for the weekend
