Review on 🌞 Moolsun 25W Solar Panel Power, XT60 DC USB Portable Waterproof Monocrystalline Solar Panel Kit for Camping RV - Support 2-4 Parallel Power Increase (100W Max) with High Output Performance and Light Strength Sensor by Dustin Wright

This is a quality solar panel that is convenient to have on hand. It has a solid aluminum frame and is fairly small and light, making it perfect for travel (e.g. camping and more). I bought it with a 24v portable power station and it works well enough to keep charged for easy use. The maximum power output I measured in bright sunlight was around 500mA/12W, so I'm not sure about 20W, but 12W is still enough to handle the load of a phone or tablet.
