RE: Solar power banks... Don't. Unless you don't have an alternative for a long time. I think it takes around 30-50 hours to fully charge most power banks, but I honestly also don't know what the discrepancies are in terms of larger solar panels (ie: Fold out ones) and side of the bank itself (ie: 10,000 mAh vs 25,000 mAh).
I think it'll charge enough to top up the bank and be enough to keep a phone well charged in a regular state, but perhaps not enough to justify the difference between a regular vs solar panel power bank.
Like, if you're going to be days up to weeks between being consistently around an outlet to charge, like a back packing trip or traveling, sure. But for weekends, I don't recommend it as an upgrade. Just get a larger basic power bank for the premium you're paying (ie: 20K or 2x 10K mAh power banks and wireless charging features). It's honestly more nuisance than benefit.
I have a solar power bank. If the world goes to #### it'll be something I have to keep a phone on airplane mode as a flashlight and a place to look at pics of loved ones... but for premium camping, it ain't something I'm contemplating.
