You can get “solar panels to charge your power bank” (e.g. I have https://www.anker.com/products/variant/powerport-solar-2-ports/A2421011 ), but is there any options for a hand crank? In case there's no light?
I see a few "hand crank radio/torches" which seem like doing 2 things, when I only want one (the hand crank power generation)
