I have both of these, have tried them out, and recommend them highly. They're solar powered lanterns by a company called D.Light whose altruistic goal is to provide low cost solar lanterns to the 3rd world. I have the 3rd, highest powered lantern, as well but have a harder time charging it than these 2. These 2 charge even on low level light. http://www.amazon.com/d-light-Solar-Rechargeable-S2-Light/dp/B00BJF86A6/ref=sr_1_2?ie=UTF8&qid=1385417229&sr=8-2&keywords=d.light

Like I said, I bought them, myself and use them camping, etc. Good luck :)
