The solar charger has a solar cell efficiency of up to 20%, a dual output voltage of 18v-5v and a power of 20W, making it ideal for maintaining the batteries of cars, motorcycles, tractors and even ships. It also offers you two.
Charging method:
1.
Insert the attached plug into the socket and point the panel in as many directions as possible.
2.
You can also use the alligator clip to connect it directly to the battery. You can attach the panel to the windshield.
Please note:
This machine is not suitable for your vehicle's dead battery. As a solar cell maintainer, the solution is to charge your battery to extend its life expectancy.
In addition, it is recommended to unplug the charger at night in case the diode is blocked and not able to block all reverse discharges.
