Instructions for Use: 1. Point the solar panel towards the sun. The USB output port on the back will light up red, indicating normal current output. 2. Connect the USB 2.0 data cable to the USB output port. The USB output voltage is 5.0V DC. 3. Connect the corresponding DC alligator clips.

The alligator clips generate a 12V DC voltage (14V open circuit). Note: During use, do not allow the positive and negative alligator clips to touch or connect, as this could cause a temporary interruption or damage to the heating circuit. Package Contents: 1 solar panel, 1 user manual (English/Chinese), 1 alligator clip, 1 lighter. This package contains only the items mentioned above and no other products. Note: Due to differences in lighting and display, the color of the items in the photo may slightly differ from the actual product. A margin of error of +/- 1 to 3 cm is possible. Precautions: 1. Use the solar panel outdoors in direct sunlight. Using it in cloudy weather or through a window may result in insufficient discharge capacity or a power outage. 2. The solar panel should be oriented towards the sun and tilted at a 30-40° angle to the ground. Direct ground placement significantly reduces its efficiency. 3. Do not leave the charger outside in the rain to avoid short circuits. The front of the solar panel is waterproof, but it is best to prevent water from entering the USB and DC ports. Do not scratch the surface of the solar panel with sharp objects.
