★ Brand New, Unused ★ Free Shipping ★ 【Most Powerful Airflow & Rear Airflow】Neck Fan Neck Cooler 4000mAh Long Continuous Use Foldable Neck Fan 4 Air Ducts Neck Fan Portable Fan 3-Level Airflow 360° Airflow Hands-Free Blade-less Heatstroke Prevention Hiking/Sports Viewing/Fireworks Display/Outdoor Activities/Commuting Conventional fans have revealed shortcomings such as "wind only from one side," "no cooling effect on the neck," and "battery life is so-so." To overcome these shortcomings, we have created a new genre of "foldable fan" called the "Evolved Neck Fan" based on 10 years of fan patent technology and 6 years of research and development, with 5000 prototypes. We always consider the user, listen to the voices of those who have purchased our products, and improve by repeatedly prototyping, verifying, and addressing even minor issues. 【Unimaginable Airflow & 8x Airflow UP】For the first time in the industry, we have developed a DC motor that has never been used in conventional neck fans! Equipped with four innovative turbines, we have evolved with our unique technology to reproduce natural wind. This enables ultra-high-speed airflow from all directions, allowing for rapid airflow in 3 seconds in any situation. The design circulates air behind the neck, delivering 360° airflow. For those who want to get through the rainy season and hot summer, on hot days, or on days when the sun is a concern, it instantly sends cool air from the neck to the whole body. 【4000mAh Large Capacity & Long Continuous Use】Equipped with a 4,000mAh large-capacity battery, the energy-efficient, long-lasting battery saves on cooling costs and maintains comfort for a long time! ○ Approximately 14 hours on low mode, approximately 8 hours on medium mode, and approximately 6 hours on high mode. It is used in high-temperature work environments where air conditioning is difficult to install, such as construction sites, kitchens, agricultural sites, home delivery services, factories, and warehouses. 【Angle Adjustment Function & Foldable】Designed based on ergonomics, the neck fan's arm can be adjusted 150 degrees. It fits well with a thick neck. The newly developed foldable design allows you to easily carry it in your bag, and you can use it as a hands-free fan around your neck anytime, anywhere. The neck arm uses a contact-cooling material that is gentle on the skin and also has a cooling effect. The lightweight design puts almost no burden on the neck.
