Brand: SOLPERK
Our company has an experienced professional technical team to help customers solve various solar charging problems, so that we can use pollution-free solar energy. That batteries will slowly leak after being stored for a period of time. And it will consume power for a long time, which will make the battery unchargeable. Therefore, we can use our solar charger to charge and maintain the battery.
This product has the following characteristics: :

1. Using high-efficiency polycrystalline solar cells, even if the panel is smaller than the traditional model, it still can achieve higher power efficiency.
2. Equipped with a charging controller, it has various protection functions that never cause any damage to the battery.
3. It is convenient to charge as long as there is sunlight to charge the battery.
4. Easy to connect. No need to pull long and complicated extension cords. At the same time it works under human body safety voltage and is very safe.
5. The surface is made of glass and easy to clean.
Reminder:
1. Before connecting the wires, separate the red and black clips to avoid collision and short circuit.
2. This product is a solar charging board which should be installed in a place where the sun is shining directly. The more sunlight, the better the charging effect.
