Cleaning
To clean the fan, gently wipe the exterior surfaces with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water. Ensure the air inlets and outlets are free from dust and debris for optimal performance.

Check the battery level on the LED display. Recharge the fan if the battery is low. Ensure the power button is pressed and held correctly for a few seconds to activate the device.
- Weak airflow:
Inspect the air inlets and outlets for any obstructions like dust or lint. Clean them if necessary. Ensure the fan is fully charged, as low battery can affect performance. Increase the fan speed setting to a higher level.
- Battery not holding charge:
Verify that the USB-C charging cable and the power adapter are functioning correctly. Try using a different cable or adapter if available. If the issue persists, the battery may require service.
