I previously purchased this item here, but I haven't had a chance to use it, so I'm putting it up for sale. 【3-Stage Wind Speed Adjustment & 2-Stage Cooling & Enjoy the Coolness】You can choose from 3 wind speeds: low, medium, and high. Simply press the power button repeatedly to switch to the appropriate speed. Cooling can be selected in 2 stages: low and high. You can also switch the cooling mode on/off with the snowflake button. 48 fan blades gather the wind, and 32 air outlets provide powerful and swirling 360° uniform airflow. With a cooling plate, the cooling effect is improved by 400%, providing instant cooling and a perceived temperature of -15°C. 【Type-C Rechargeable & 4000mAh Large Capacity】This portable fan is USB rechargeable and supports various charging methods, including computers, charging heads, and mobile power sources. Please charge it with a 5V/1A charger. It can also be charged from a computer or rechargeable battery, which is convenient. A full charge takes about 4 hours. It has a built-in 4000mAh lithium-ion battery, allowing for up to 8 hours of continuous use. 【Easy to Use & Simple Button Switch】Press and hold the power/wind speed button for 3 seconds to turn it on. Each press of the power switch cycles through "low wind" ⇒ "medium wind" ⇒ "high wind," and pressing it again turns it "OFF." The wind speed and cooling buttons are controlled separately. Each press of the cooling (snowflake) button switches between low and high cooling. Pressing the cooling button again turns off the cooling function. The operation is simple and can be used by the elderly and children. 【Quiet Design & Great for Commuting】Upgraded in 2025, the use of ABS material and a high-quality brushless motor minimizes noise. The operating noise is less than 40dB. The low noise allows you to enjoy a comfortable and quiet environment.
