USB fan stepless speed controller!

Principle of fan speed regulation:

    The non-adjustable USB fan is a 5V direct-supply fan motor, and the two-speed fan has a booster circuit board inside. When placed in the second gear, the booster board will raise the 5 volts of the USB. Connect the motor, the air volume will be large!

    The output voltage range of the stepless speed regulator smoothly changes from 2.5V to 8.0V, and the air volume can be set arbitrarily! And the scope is wider! Turn the knob clockwise to increase the air volume, turn it counterclockwise to decrease the air volume, and the knob has a switch function!

Instructions:

     Plug the male connector of the speed controller into the mobile phone charger, power bank, computer USB, etc., and then insert the fan plug into the female connector of the speed controller! Or use Micro USB 5.0V power supply.
