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

This solar charger can fully charge the car battery and extend the battery life. It is very easy to use - just plug it into the 12V socket on the dashboard. The charger is not powerful enough to charge a very weak or dead battery. If your 12 volt outlet is not hot (live) when the engine is not running, the kit includes the wire connectors needed to connect two additional ways. The charger comes in very handy when your car sits idle for several days without moving. Park your car so that the front is not in the shade and faces the direction where the sun is in the sky for most of the day. Then connect the charger and place it in the windshield on the dashboard. It typically takes an hour or less a day to fully charge the battery in bright sunlight.
