I made a video last year about charging my boosted board from my Yeti 400 solar generator. This is a SUCCESSFUL re-engineering of that system, designed to get size and weight down to a level that can be comfortably transported via a backpack.
Here’s Part 1 showing assembly process: https://youtu.be/vAMekgM32Z4
Here’s Part 3, all about folding solar panels: https://youtu.be/aFuZlnsunKg
Here’s the original Yeti 400 video that started this project: https://youtu.be/VlaHBB3GRwg

These are similar to the panels used in the video (solar panels go in and out of stock quickly, so these may not be the exact brand in the video, but they’re equivalent):
