1. Pulse mode imitates natural wind-using the principle of fluid dynamics, the natural wind with smoother, wider wind range, softer and quieter can be restored. 2. The stepless speed change wind gear is cool and relaxed at will, and the DC brushless motor can adjust the wind speed at stepless speed change and switch the mode suitable for you at will. 3.90 up-and-down angle is adjusted manually, and the wind direction is controlled at will, and the wind direction is adjusted at 90-180. Strengthen the locking axis to be solid and reliable; The design of 136 automatic shaking head and automatic rotating shaking head can avoid the discomfort caused by long-term direct blowing, and it can be opened by gently pressing the shuttle knob to make the air supply range wider and meet the common use of many members. 4. The battery life can be carried for outdoor use for up to 6 hours, and the small gear and shaking head can last for about 6 hours; Using the principle of fluid dynamics, the natural wind with smoother, wider, softer and quieter wind can be restored. 5.30dB static soft wind and gentle breeze run with low noise, and the brushless motor is quieter with 3 large blades. Brushless machine core mute strong wind, original digital brushless motor, high speed to provide lasting strong wind, low wear and quiet life longer.
