Turbine motor for strong airflow: Using a high-efficiency turbine brushless motor with a rotation speed of 16000rpm, our high-quality silent handheld fan produces less than 25db of noise, but can produce powerful storm air with speeds up to 9m/s and longer cooling distance to 5 meters to 3 times to help you cool down faster in hot summer. Jet fans release compressed and concentrated air, which is filtered and cooled like the air in an air conditioner.

100-level stepless speed adjustment: Our powerful fan provides 100-level customizable wind speed to meet all your different needs. There are 2 adjustment buttons to change the speed. You can increase or decrease the numbers by pressing the "+" or "-" buttons, up or down 20 digits at a time. Additionally, you can seamlessly customize specific speed steps by holding a button, providing an incredible cooling experience.
