Product details: Thanks to integrated cooling technology, the cooling speed is fast. Thanks to integrated TEC cooling technology and environmentally friendly refrigerant, the outlet temperature can drop by approximately 11 to 16 degrees Celsius in a very short time. Compared to traditional fans without a cooling function, this provides a more powerful cooling experience. Especially during hot summers, during exercise or long walks outdoors, this function provides a significant and immediate cooling sensation throughout the body. Hidden fins ensure safe transport. The fan blades are completely hidden inside the casing, which avoids direct contact with hair or clothes. This completely solves the problem of hair tangling, which is common with traditional fans. Therefore, you can safely wear this device around your neck without worrying about hair accidentally tangling during exercise. Powerful and even airflow, and no annoying noise. A powerful brushless motor combined with a multi-stage airflow system ensures a strong and even airflow from the head to the shoulders. This allows for discreet use of this product even in quiet environments such as offices or on public transport. Easy operation, equipped with an LED display and light effects. The clear LED display makes the current operating status and other settings easily visible, which significantly simplifies daily use. Three different wind speeds are available, allowing you to adjust the airflow to your preferences. In addition, the multi-colored ambient lighting adds a touch of style, especially at night or during evening activities. The long-lasting battery has fast charging.
