Mini wind power generator alternator kit designed for DIY assembly and classroom experiments. This complete set provides a simple way to generate small amounts of electrical power from wind and to learn about wind energy and alternator operation. Key specifications Output voltage: DC 0.1 to 6 V Output current: 0.01 to 0.3 A Rated speed: 200 to 6000 RPM USB output: 5 V plus or minus 0.2 V via supplied voltage regulator Quantity: 1 set What you get and how it works Complete alternator kit that you assemble yourself, providing handson experience in building a small wind turbine. A voltage regulator with a USB output lets you connect standard USB devices. Insert the turbine into a steady wind stream and the alternator generates current that the regulator conditions to USB output. The kit requires sufficient wind speed for useful power output. Performance depends on wind conditions and assembly. Important handling and compatibility notes The alternator has a positive and negative pole. Identify the polarity before connecting to the regulator or devices. Reversing polarity can damage the unit. Output current is limited to 0.01 to 0.3 A, so charging speed and compatibility depend on the device and wind conditions. Use the regulator and a compatible USB cable for connection. This product is suitable for small electronics projects, demonstrations, and educational use rather than as a primary power source. Practical use scenarios Remote charging demonstration: Provide a lowrate USB charge to a phone or small device in windy outdoor situations when conventional power is not available; requires strong wind and compatible device behavior. Classroom experiment: Demonstrate wind to electricity conversion, alternator polarity, and basic power measurement for students learning about renewable energy. Hobby projects: Power small LEDs, low current sensors, or microcontroller projects during maker activities where wind energy is being explored. Additional information Quantity included: 1 set of wind power generator alternator. Color may vary slightly from the pictures due to monitor and lighting differences. Please allow a measurement tolerance of about 2 to 3 mm due to manual measurement. This kit provides a practical, handson way to explore small scale wind power generation, assembly skills, and alternator operation.
