Instructions：
1. First, the solar panel surface of the solar panel faces the sun, and the back USB output surface has a red light indicating that the current output is normal.
2. Plug the USB 2.0 cable into the USB output port, and the USB output standard 5.0V DC voltage.
3. Connect the mated DC alligator clip, and the alligator clip outputs a DC voltage of 12v (14V at no load). Note: The positive and negative crocodile clips cannot be connected or touched during use,
which may cause short-term heat or burn the line.
4. With the mountaineering bag, this product is suitable for low-power products with 5V power supply or low-power products with 12V power supply.


Package includes:
1x Solar panel
1x Alligator clip
1x Cigarette lighter


Tips:
1.Light intensity
The amount of electricity generated by a photovoltaic system is determined by the radiation intensity of the sun, and the amount of solar radiation is positively correlated with the amount of electricity generated. solar
Radiation intensity and spectral characteristics change with meteorological conditions.
2. Component installation method
The amount of radiation on the inclined surface is different for different installation angles in the same area. The amount of radiation on the inclined surface can be adjusted by adjusting the inclination of the panel (bracket Increased by using a fixed adjustment) or by adding a tracking device (the bracket is tracked).
3. Component occlusion
Component occlusion includes occlusion of dust, snow cover, weeds, trees, panels, and other buildings, and occlusion will be reduced.
The amount of radiation received by the component affects the heat dissipation of the component, causing the component output power to drop and possibly causing hot spots.


Note:

1. Please do not scratch the surface of the solar panel with a sharp object.
2. When charging the charger with solar energy, please place the solar panel upwards in direct sunlight to ensure the charging effect.
3. Please do not put the charger outdoors on rainy days to avoid short circuit. The front of the solar panel is waterproof, but it is best not to enter the water at the USB and DC interf
