Solar energy for the car battery. During the winter break for motorcycles or boats, when temporarily putting the car out of service, for electric fences or campers: The solar cell converts solar energy into electricity, allowing for independent charging of 12V lead-acid batteries. And all of this is ecologically sustainable and location-independent. Even low sunlight is sufficient to prevent battery discharge. The solar battery protector can be easily connected via the terminals or, if technically possible, through the cigarette lighter. For permanent installation of the charger, which is dustproof and splash-proof according to IP64, screws and plugs are also included along with the two 0.5-meter long cables. Special feature: Amorphous solar cell.
