  1. Check whether USB power can maintain operation normally at a low fan speed. If it can, the device’s USB power supply and related functions are working properly.
  2. USB-C charging power may not be enough to cover the power consumption required for high fan speed operation. If you use the device at medium or high fan speed for a long time, we recommend using the AC power cable to keep it powered.
