【Industry First! Equipped with Four Turbo Fans, Front and Back】 For the first time in the industry, we have succeeded in developing a DC motor that has never been used in conventional neck fans. This innovative fan is equipped with four turbines and utilizes unique technology to reproduce natural wind. 【Unprecedented Air Volume & 4000mAh Large Capacity Battery】 The industry's first design with four turbo fans enables ultra-high-speed airflow from all directions, allowing for rapid cooling in 3 seconds, no matter the situation. The refreshing breeze that passes from your neck to your entire body will leave you feeling refreshed! With 8 times the airflow compared to conventional models, you don't have to worry about makeup smudging or heatstroke! In addition, it is equipped with a 4000mAh large-capacity battery, allowing for long hours of continuous use, and its unique safety design ensures safe use even for extended periods. 【Angle Adjustment Function & Foldable】 Designed based on ergonomics, the neck fan's arms are adjustable up to 150 degrees. The newly developed foldable design allows you to easily carry it in your bag, and you can use it as a neck fan anytime, anywhere. 【Rear Airflow Function & Three-Stage Adjustment】 As the industry's first newly developed neck cooler, it also has a rear airflow function, making it possible to blow air to the back of the head, which is effective in preventing heatstroke with powerful airflow from all directions. In addition, you can choose your preferred wind strength according to the place you are using and the heat, as you can adjust the wind volume in three stages: weak, medium, and strong, by simply pressing a button. 【Safe and Secure Protection Design】 Compared to regular batteries, we use a safer 4000mAh battery. We have repeatedly improved the product to create a safer product, and with safety protection circuit designs such as over-power and over-current protection, you can use it safely even for long hours of continuous use. 【Notes】 Please charge with the included cable. Foldable: Adjustable up to 150 degrees, so please adjust to the optimal angle when using.
