Review on 🌞 POWISER 10W Solar Battery Charger for Automotive, Motorcycle, Boat, Marine, RV, and More - 12V Solar Powered Battery Maintainer & Charger (10W Poly) by Steve Snyder

Product works great. My only complaint is that the SAE power connector on the unit is reversed so compared to my other plug-in the positive is on the negative side and the negative is on the positive side. Charger, so when I plug it directly into an SAE outlet to charge the battery it doesn't work. Since the polarity is reversed, you must use the connector on the adapter and tie it directly to the battery.
