Review on ECO-WORTHY 12V 10W Solar Battery Charger & Maintainer with Alligator Clip Adapter 🌞 - Portable Car, Boat, Automotive, Motorcycle, RV Solar Panel Trickle Charger & Power Backup Kit by Chris Hernandez

Very happy with this purchase. I have another more expensive solar charger (hard panel) and I like it much better. The 1 star reviewers don't understand the purpose of the solar charger, it's not to charge a battery, it's to keep it going. If you put a discharged battery in a solar charger, it will remain discharged but will not lose more power than it has already lost. Batteries often die within a week or two if you are not driving this will prevent this from happening.
