Fan speed regulation principle:

A USB fan without a gear is directly connected to the fan motor with a USB 5V power supply, while a fan with two gears has an internal boost circuit board. When placed in second gear, the boost board raises the USB 5V power supply and then connects it to the motor, resulting in a higher air volume!

When using a USB fan speed controller, please place the fan in first gear, otherwise it may not be possible to adjust the speed!!!

Usage:

1. First, insert the male connector of the USB fan speed controller into the power interface of the phone charger, power bank, computer USB, etc. (ensure that the power of the power interface is greater than the required power of the fan or LED light power), then insert the USB fan plug or USB desk light plug into the female connector of the USB fan speed controller. The default output of the governor is turned on.

2. The output voltage of the left dial button increases; Right shift output voltage decreases.

3. Click the dial button to switch the output on or off.

4. Double click the dial button to turn off the digital display, and press any button to wake up the digital display.

Timed time setting:

1. Long press the dial button for 3 seconds to enter the timed time setting interface. "---" represents timed off, and the displayed number represents timed on.

2. In the settings interface, click the dial button to switch the timer function on or off.

3. In the settings interface, press the left dial button to increase the timing time, and press the right dial to decrease the timing time.

4. Press and hold the dial button for 3 seconds to exit the timed time setting interface and start.

Voltage limit threshold setting:

1. Press and hold the dial button twice for 3 seconds, and the voltage limit threshold setting interface will display "H" and a number "H" represents the voltage limit, and the number represents the specific voltage value in V.

2. In the settings interface, press the left dial button to increase the voltage limit threshold, and press the right dial to decrease the voltage limit threshold.

3. Press and hold the dial button for 3 seconds to exit the timed time setting interface and return to the normal interface.
