Solarpunk

Yeah but, what about all the other battery generators that have already existed for years? Small rugged generators are already a thing, why is this one different? What am I missing here?

Why are those things important for solarpunk though? Why is that the most solarpunk thing ever, when equally (arguably more) capable portable battery packs have existed for at least a decade. I have a half dozen of various sizes, they are very rugged and some of them are very lightweight. (The better ones use LiFePo4 batteries and are vastly safer but therefore also somewhat heavier relative to their power and capacity but you can choose whichever you prefer to optimize for)
