No batteries, no problem. Solar-powered flashlights are here to save the day.
There's a time and place to hate on solar energy, but I think we can all agree that solar power is neat when it comes to survival products. Solar-powered flashlights are becoming popular survival tools for campers (and doomsday preppers).
These nifty flashlights use the sun's energy to charge, which means you don't have to worry about having batteries ready. However, some can be charged with USB cables as well. It's nice to know that you have another way of keeping a charge on your survival products! Here are six flashlights Amazon customers swear by.
