Very very cool. Thanks for sharing that video.
There are days you will not want to crank it. Look into building a small solar powered 12 volt system, that will free up your hands to do other things....a great source of emergency power that I can add to my emergency kit! Great job! Any other great ideas to add?
I'd actually while you have it open , replace the cell batteries with a bigger vape one or something! Great ideaLearn How-To in Less Than a Minute!
I found a really cool video that I wanted to share with you guys. If you have a spare hand-crank flashlight you can turn it into a cellphone charger.
