Manual 1. First, the surface of the solar panel faces the sun, and a red light will appear on the USB output surface on the back, indicating that the current output is normal. 2. Insert the USB 2.0 cable into the USB output port. The USB output voltage is a standard 5.0V DC. 3. Connect the corresponding DC alligator clips. The alligator clips produce a DC voltage of 12 volts (14 volts open circuit). Note: The positive and negative alligator clips must not be connected or touched during use, as this may cause short-term interruptions to the heating circuit or burnout. 4. This product is suitable for low-power products with a 5V power supply or low-power products with a 12V power supply.

Precautions: 1. Please use it outdoors in a sunny location. Using it in cloudy weather or through a window may result in insufficient discharge capacity or power failure. 2. The solar panel should face the sun and be at a 30-40 degree angle to the ground. If placed on the ground, the conversion effect will be very low. 3.
