Fan speed principle:
The non-adjustable USB fan is a 5 volt electric fan motor directly, while the two-speed fan has a boost circuit board inside.When placed in the second gear, the booster board raises the USB 5 volts.When the motor is connected,the air volume will be big.The stepless governor output voltage range varies from 2.5 volts to 8.0 volts, and the air volume is arbitrarily set!And the scope is wider! Turn the knob clockwise to increase the air volume, counterclockwise to reduce the air volume, and the knob with switch function.
