Made for Battery Maintenance
The solar battery charger is essential if you have seasonal vehicles that sit for months without being used. With this unit, your vehicle's battery will still be as fresh as the day you left it. It's designed to fully charge a battery and maintain it at proper storage voltage with free energy source - the sunlight.
18W SunPower Solar Panel
The solar charger has a high solar cell efficiency of 22.5%, and output voltage of 18V with 18W of energy, which is better than 4.5W, 7W of similar product on the market. It's made of polycrystalline which is more efficient than monocrystalline silicon.
Two Ways of Charging
Simply plug the included cigarette lighter plug in the socket and place the panel facing the direction with the most sunlight possible. You can also use the crocodile clips to connect it directly to the battery. You can mount the panel on your windshield with the 4 suction cups.
