Product description

The charger will not overcharge the battery, and there are reverse diodes on the board to ensure that the battery power is not wasted at night.
The product is compact in small size and can be installed outdoors.
It can also be used to maintain automobiles, trucks, all-terrain vehicles, motorcycles, ships, farm equipment or any 12V battery applications.

Reminder:

If the car is charged, do not use it when starting the car and driving to avoid the surge of the car engine may damaging the solar charger.
