Good news! The best and most rugged solar battery for outdoor (hiking) use is the”Waka-Waka”. The brand also helps hundreds of thousands of children in refugee camps and remote off-grid areas to read and learn at night. And the”Waka-Waka” company just relaunched.
If you buy one for yourself, another person will also get access to light.
The “WakaWaka Power+” gives you light (instead of having to use a smoking oil lamp) and can charge mobile phones/ cell phones/ smartphones for connectivity .
Available from stores, see the list at: https://waka-waka.com/
These things make a difference in the lives of many in the world, not only yourself.
