Is cooking in the summer unbearably hot? Does the slow heating of your heater in winter give you a headache? Does the noise of your fan bother you when you're trying to sleep? Then you need this silent fan. It can be used as a ceiling fan or a table fan. It automatically adjusts the airflow based on your body temperature while effectively reducing noise. Features include turbine blades, a concentrated airflow design, four adjustable wind speeds, and easy operation. A silent motor effectively reduces noise. No drilling required, allowing for flexible hanging. A high-capacity battery makes it compact and portable. The turbine blades and concentrated airflow design achieve a wind speed of up to 5.24 m/s and a rotation speed of up to 2250 rpm. Thanks to the extended airflow duct inside the unit, it can quickly lower body temperature in summer and quickly raise the temperature of your heater in winter. Four adjustable wind speeds and easy operation: This fan offers four wind speed modes: gentle breeze, comfortable breeze, strong breeze, and sleep breeze. These modes are all steplessly adjustable, and the fan head can rotate 90°. The knob, located on the back of the fan, allows you to adjust the wind speed and angle to meet your different needs. A silent motor reduces noise pollution. This fan uses a silent motor with a noise level as low as 25 decibels, quieter than a light rain, effectively reducing noise disturbance during sleep. The built-in hook allows for flexible hanging; you can hang the fan anywhere—in the kitchen, on your desk, beside your bed, or anywhere else—for easy portability. A large-capacity battery keeps it compact and portable. This fan has a built-in 4000mAh 18650 lithium battery, providing up to 19 hours of continuous use, so you don't have to worry about power even when using it outdoors.
