My Megasolar 100W foldable solar panel (https://amzn.to/2YNf6xV) has finally arrived (the post seems to have lost it for a week). It has both a USB Type-C + PD that outputs 20V and a DC output that can be configured to output 12/15/20V. There are a number of adapters available. I was able to charge my Ryobi One+ 18v batteries using an adapter I made (see #4582408 for things) both via the 20v plug and via the USB Type-C cable at the same time! I can charge my Dell Inspiron 15 laptop or my Suaoki S200 Powerstation (https://amzn.to/3gHPfh7) directly. It's really designed to run a laptop, not charge a trailer battery. It doesn't have MC4 connectors that you could use to daisy chain or parallel them. The packaging is beautiful. It folds down to the size of a folder (much smaller than my Renogy 100W folding panels https://amzn.to/3jy3Xcw). The only negative I can say at the moment is that it came without a cable. So I contacted the seller. If I don't get a replacement quickly, I'll downgrade my rating because of the service, not the product.
