Features Compact - Wind turbines are small, light and easy to carry. It can work in the breeze and is very suitable for demonstration. It can be used as a teaching experiment of wind power generation, with stable performance and strong practicability. With LED lamp - This generator is equipped with LED lamp, which has low power consumption. The fan on the generator is enough to light the LED. It is a brand new high-quality, reliable and safe generator. The generator can be used as a scientific model with fine workmanship and smooth appearance. This is a good teaching tool for wind power generation. I believe it can bring convenience to your life. 360 degree rotation - The wind turbine can work no matter from which direction it blows, it will automatically face the wind direction, and has a wide range of effects and obvious effects. It is very suitable for DIY - you can assemble and disassemble by yourself. It does not take too long. It is easy to use and operate. It is very suitable for cultivating children's hands-on ability and interest. Warm prompt: "Wind level: the third level starts to generate electricity and lights up the LED. This generator is suitable for demonstration of wind power generation and lights up the F5mm red LED. For other purposes, it must have certain electronic and electrical technology. Without basic knowledge of electronic and electrical technology, please do not use it in other areas, so as to avoid being unavailable and inappropriate after buying it back."
