>>2216159Those are pretty small and weak panels. If you were looking at that, you would be better off bringing two large regular power banks without the tiny solar panel. They claim max 6W of power, but that’s going to be perfect summer sun and keeping the thing aimed perfectly and maybe you can recharge the bank to 50% over 12+ hours of direct sun.
It you want to get anything from the solar panel, you need something more like pic related, and even that one is going to be more like supplemental power hanging off a backpack.
