Thanks for the inspirational links! But all those things are huge! My personal goal is to fit all of my power making stuff in EDC kit (on-body EDC!). So the primary criteria for me is how thick it is. Anything more than 3/4 inch (2cm) thick - is not acceptable!

38mm thick solar panel (Explorer)??? Mine is 6 times larger in square inches but only 3mm thick folded with the same footprint!
