Product Components

Setup
1. Charging the Battery
For optimal performance, fully charge the fan before first use. The fan is equipped with a rechargeable battery that provides portable cooling.
- Locate the Micro-USB charging port on the clip base of the fan.
- Connect the included USB charging cable to the fan's Micro-USB port.
- Plug the other end of the USB cable into a compatible USB power source (e.g., computer, USB wall adapter, power bank).
- The charging indicator light will illuminate (color may vary by model, typically red or blue) to show that the fan is charging.
- Once fully charged, the indicator light may change color or turn off. A full charge typically takes several hours.
2. Installation and Placement
The versatile design allows for various placement options:
- Using the Clip: The heavy-duty clip allows you to securely attach the fan to desks, shelves, strollers, or other surfaces up to a certain thickness. Ensure the clip has a firm grip to prevent the fan from falling.
- Desk Stand: The clip base also functions as a stable desk stand when placed on a flat surface.

3. Adjusting the Gooseneck
The flexible gooseneck allows for multi-directional airflow. Gently bend and position the gooseneck to direct the fan head to your desired angle. Ensure the gooseneck is securely positioned to maintain the fan's direction.

Maintenance
