I discovered this by chance last year while packing for camping. I took my 2 outdoor solar lights to use in my tent. These have a flat bottom because they hang from small shepard hooks. I put them outside the tent door in sunlight to recharge during the day and brought them inside at night. Worked great and were fireproof.

If you are a camper, you have probably at one time or another experienced having a very dark campsite. I have a simple and inexpensive solution for you. Pack one of the solar yard lights to take with you camping.
I purchased a wind up flashlight to use, never have to worry about if I bought enough batteries or if they will last long enough. A minute of cranking will last about 20 minutes and that's usually enough time to get to the shower house/restrooms.
