DC 4V-12V 5W XY-FS USB Fan Stepless Governor USB Fan Speed Controller Multi-Gear Auxiliary Cooling Tool

     USB fan speed controller, wind speed and air volume regulator, heat dissipation, noise reduction, multi gear office dormitory, bedside mini

Module highlights:

● USB fan air v a aolume regulator!

● Strong and weak winds can be adjusted freely!

● USB fan infinite speed controller!

Fan speed regulation principle:

      The non adjustable USB fan is a 5-volt direct supply fan motor, while the two speed fan has an internal boost circuit board. When placed in the second speed, the boost board raises the USB's 5-volt voltage before connecting to the motor, resulting in a higher air volume!

      The output voltage range of this stepless speed controller smoothly varies between 2.5 volts and 8.0 volts, and the air volume can be set arbitrarily! And the scope is wider! Turning the knob clockwise can increase the air volume, while turning it counterclockwise can reduce the air volume, and the knob has a switch function!
