The input power supply is DC 5V for the non-adjustable USB fan. There is a boost board inside for the two-position fan. The boost board step up voltage for motor in the fan when in second gear causes the fan to go faster. The stepless governor output voltage range varies from 2.5 volts to 8.0 volts.The wind speed is set arbitrarily. Turn the knob clockwise to increase the wind speed. Micro USB and male USB are input terminals that are used to connect to the power supply. The female USB is an output, which is used to connect to the fan.
When using the two-speed adjustment fan, please put the fan in first gear, otherwise it may not be able to adjust the speed..
