Did You Know?
Wind turbines can produce electricity in over 90% of the world’s land area.
The world's largest wind turbine can power over 10,000 homes!
Materials Required
Before starting, gather these components:
Component | Quantity | Description |
Mini Wind Turbine | 1 | Captures wind energy and converts it into mechanical energy. |
Small DC Motor | 1 | Acts as a generator to produce electricity. |
USB Charging Module | 1 | Converts generated electricity to a stable output for charging. |
Wires & Connectors | Several | Connects different components for power transfer. |
LED Indicator (Optional) | 1 | Shows when power is being generated. |
Mounting Board | 1 | Provides a stable base for the project. |
Small Fan Blades (3D Printed or Pre-made) | 1 Set | Used to capture wind efficiently. |
Hot Glue Gun | 1 | Secures components in place. |
Building the Wind-Powered Phone Charger
Step 1: Assembling the Wind Turbine
Attach the fan blades to the small DC motor securely.
Mount the motor onto the stand or board to ensure stability.
Position the turbine where it can capture strong airflow—outdoors or near a fan for testing.

Step 2: Connecting the Generator
Identify the positive and negative terminals of the DC motor.
Connect wires to the terminals and extend them to where the USB charging module will be placed.
Step 3: Wiring the USB Charger
Component | Connection |
DC Motor - Positive | USB Module - Input Positive |
DC Motor - Negative | USB Module - Input Negative |
USB Module - Output | Connects to charging cable |
Secure all connections using a hot glue gun or soldering iron.
If using an LED indicator, connect it in parallel with the USB module to visualize power flow.
Step 4: Testing the Setup
Place the turbine in front of a strong airflow source (fan or outdoor wind).
Connect a USB charging cable to your phone.
If everything is working, your phone should start charging using pure wind energy!
If no power is generated, check connections and wind speed.

Answer Key:(A) Wind Energy
FAQs
1. How much power does this wind charger produce?
Ans. It depends on wind speed, but it can generate enough power to charge small devices.
2. Can I use a bigger wind turbine?
Ans. Yes! A larger turbine will generate more power and charge devices faster.
3. What if my charger isn’t working?
Ans. Check all wire connections, ensure proper wind exposure, and test with another device.
4. Can this be used as a permanent phone charger?
Ans. For a consistent power supply, consider adding a battery storage unit to store energy for later use.
