Review on 🌞 Renogy Portable E.Flex Monocrystalline 5W Plus Solar Panel: Efficient Charging on the Go for Hiking and Biking with USB Port by Amy Weaver

I am currently traveling long distance trails in the Middle East deserts so I use it every day. For the record, I've been using solar chargers for hiking for 10 years and recently bought this one because my favorite was wearing out from all the scratches. Here's the riddle: the panel worked flawlessly during pre-ride testing, and then for two weeks in the Jordan desert I was very happy with my battery and everything I had with it. And the last 2 weeks everything is exactly the opposite: it no longer produces energy. Here in the desert, I'm always under clear skies, trying to change all the variables: cable, battery, exposure, temperature. it just won't work. He thinks maybe something broke in the USB socket, but I know it wasn't due to mishandling or water :( I've only noticed a few other reviews that had similar cryptic errors. I want so desperately that it works again, it's critical for my gps navigation.
