1.180 and adjust the air supply automatically up and down 90, which can not only automatically shake your head about 180 and supply air in a large area, but also manually adjust the air supply angle up and down 90, making the distance and height refreshing. 2. Strong endurance, continuous air supply hours, built-in 2000mAh rechargeable battery, and only 7W energy-saving design, the endurance time of the first wind speed is as long as 5 hours, the second gear is 3.5 hours, and the third gear is 2 hours Using brushless copper-core motor, running softly and slowly can not only reduce the sound when running, but also reduce the power consumption, which is more energy-saving and electricity-saving. 3. One-key switching of three-speed wind speed, simple design and simple life The first gear: the refreshing experience of the breeze The second gear: refreshing and double sweeping away the sultry Third gear: strong wind speed and instant coolness. 4. Newly upgraded 7 turbine blades are strong and soft, and 7 inclined and rotating blades are more powerful Innovative aerodynamic design, aerodynamic design can be reduced with external environmental factors Air resistance, compared with similar competing products, the wind speed increased by more than 20 percent , and the work efficiency jumped by 30 percent . 5. Easy-to-remove masks are easier to clean, and fans will naturally cause dust accumulation for a long time, which will affect health. We design easy-to-remove masks to clean the fan blades more easily.
