The built-in LED lights automatically cycle through 7 colors, including red, orange, yellow, green, blue, indigo, and violet rainbow colors. The current version of the fan does not support manually setting a fixed color; it's designed primarily for automatic cycling to add fun and practical lighting functionality for nighttime use. Each color stays for about 3-5 seconds, with the entire cycle flowing naturally to create a brilliant visual effect.

The fan shell is made of high-quality PC (polycarbonate) material with special pearl powder treatment, which not only creates a unique pearl luster effect but also maintains the excellent properties of PC material, including lightweight, impact resistance, and durability. This material is more robust and durable than ordinary plastic and can withstand daily impacts and friction. However, it's recommended to avoid dropping from heights or heavy pressure to extend the aesthetic appeal and service life.

The double-click power-on design prevents accidental activation of the power button in bags or pockets. To use it, you need to quickly press the power button twice within 1 second to start the fan. After the first press, there may be a slight indicator light flash, prompting you to press again. Once successfully turned on, the fan will start at low speed by default, and you can press the button again to cycle through speeds (Low→Medium→High→Rhythm Wind→Off). This design effectively prevents accidental power consumption and unintended blade rotation.

Rhythm wind mode is a feature designed to simulate natural wind. In this mode, the fan automatically alternates between different wind speeds, creating an effect similar to natural wind that varies in strength, avoiding the monotony of continuous single-speed airflow. This design not only provides a more comfortable user experience but also reduces the dryness and discomfort to skin and eyes caused by prolonged exposure to fixed wind speeds. Rhythm wind mode is particularly suitable for extended use, such as in the office, while reading, or before sleep, offering a more natural and comfortable wind sensation.

Yes, this product supports using while charging. However, to protect battery life and avoid overheating, we recommend prioritizing battery power mode when conditions allow. Extended use while charging may lead to increased body temperature and reduced battery cycle life. If you're low on power during outdoor activities or business trips, you can connect to a power bank to continue using, but it's advisable to select an appropriate wind speed and avoid operating in high-speed mode for extended periods to reduce heat generation and extend device lifespan.
