Speed principle:
The non-adjustable USB fan is a 5V electric straight power supply, and the two-speed fan has a boost circuit board inside. When placed in the second gear, the booster board raises the USB 5V and then connects the motor to the air volume. It is big. The output voltage range of the stepless governor varies from 2.5V to 7.5V. The air volume is arbitrarily set and the range is wide. The clockwise knob can increase the wind speed, the counterclockwise knob reduces the wind speed, and the knob has a switch function.
Note: When using the second gear to adjust the fan, please put the fan in the first gear, otherwise it may not be able to adjust the speed.
