the d.light solar lanterns are wonderful. I have a couple of them and one of the task lights. For your needs I would be more inclined to buy couple of those, a $30 8 watt Anker solar panel or, planning ahead, in case you have other electronics, a $60 14 w panel. http://www.amazon.com/Anker%C2%AE-Dual-Port-Charger-PowerIQ-Technology/dp/B00E3OL5U8/ref=sr_1_1?s=electronics&ie=UTF8&qid=1424032021&sr=1-1&keywords=anker+solar

And of course, a $19 back up battery for cloudy, rainy days: http://www.amazon.com/5200mAh-Compact-Portable-External-Technology/dp/B00P7N0320/ref=sr_1_6?s=electronics&ie=UTF8&qid=1424032304&sr=1-6&keywords=anker+lipstick+charger
