Powering the Fan

Operating Instructions
Power On/Off and Speed Control
The fan features a control switch, typically located on the side or back, with the following settings:
- OFF: Turns the fan off.
- LOW: Activates the fan at a lower speed for gentle airflow and extended battery life.
- HIGH: Activates the fan at a higher speed for maximum air circulation.
Smart Power Technology
The fan's Smart Power technology automatically prioritizes the most energy-efficient power source available. For example, if both the AC adapter and D-cell batteries are connected, the fan will primarily draw power from the AC adapter, preserving battery life.
USB Charging Port
To charge your mobile devices, connect your device's USB charging cable to the USB output port located on the side of the fan. The fan must be powered on or connected to an AC source for the USB port to function.
Adjusting Airflow Direction
The fan head can be manually tilted up or down to direct the airflow to your desired angle. Gently push or pull the fan head to adjust its position.
Maintenance
Cleaning
Regular cleaning helps maintain optimal performance.
- Always unplug the fan before cleaning.
- Use a soft, damp cloth to wipe the exterior surfaces.
- Do not use abrasive cleaners or solvents.

Battery Care
- For rechargeable batteries, fully charge the fan before first use and periodically if stored for long periods to maintain battery health.
- Remove D-Cell batteries if the fan will not be used for an extended period to prevent leakage.
