Review on 🌞 Efficient Newpowa 50W Solar Panel for Battery Charging on Boats, RVs, Campers, SUVs, and Off-Grid Applications by Marc Cahoon

I bought this solar panel and charge controller to charge a car battery that was too far from an outlet for my charger. When I checked the battery it went back to 11.5 volts on its own after a few weeks of idling. the engine did not turn. After purchasing this panel and a charge controller, the engine started immediately after 8 hours of sunlight. A day later the battery voltage was 13.8 volts. I hooked everything up to make the charge controller and 50 watt panel portable so I can use it anywhere and at almost 3 amps this panel could have many practical uses.
