Working Principle:
For USB fans without gear, USB5V power supply is directly connected to fan motor. There is a boost circuit board inside two-speed fan. When running in the second-speed, the boost board will raise USB 5V power and then connect motor, and the air volume will be large.

When using a USB fan speed controller, please make your fan run at first-speed,  otherwise the speed may not be adjusted.

Using Methods:
1. Plug the male port of USB fan speed regulator into the power port of your mobile phone charger, power bank, computer USB (make sure that the power of power port is greater than the power required by your fan or the power of LED light). And then connect USB fan or USB desk lamp with female port of our product. The governor's default output status is on.
2. Thumbwheel: Turn it to the left side to increase voltage. Turn it to the right side to decrease voltage.
3. Click the thumbwheel once to turn output ON/OFF.
4. Double-click the thumbwheel to turn off digital tube. Press any button to wake up the digital tube.

Timing Setting:
1.Press and hold the thumbwheel for 3 seconds to enter into time setting interface. --- represents timing off, and number displayed represents timing on.
