Review on ⚡ Efficient 20W Solar Panel Car Battery Charger: Portable, Waterproof, Ideal for Car, Boat, RV | POWISER by Jessie Ritchie

This is a 20W solar panel. I hooked it up to a small air pump that only draws 6 watts and barely works even in full cloudless sun. The blue charge indicator light came on and as soon as I connected the pump all the lights went out. I connected the pump to the battery and everything worked. Others who reviewed the air pump said they were able to run it on solar power, so I believe it's a panel and not a pump. I would expect it not to be as efficient or powerful as advertised, but far from it.
