The solar trickle charger for car battery is an eco-friendly 1.5-watt, 100-mm charger that harnesses the power of the sun to slowly charge your car battery.
This handy solar panel connects directly to your battery to provide a continuous charge that prevents discharge even when your vehicle is idle.
Its amorphous silicon solar cell is durable and efficient at converting sunlight into charging power.
Simply place the panel on a sunny spot on your dashboard or exterior roof and let the free solar energy work its charging magic.
WARNING: Battery charging using the 12 V cigarette lighter socket is only possible when the voltage in the socket is present even after the engine has been turned off and the starting key has been removed.
