1. This turbofan has a simple design, reasonable structure, and strong performance. The wind speed exceeds 45m/S. 2. Use a 32mm diameter customized low-voltage brushless high-speed motor (the 32mm motor uses 4-pole sintered magnets, which has high efficiency, low heat generation, and produces extremely strong wind power with low power, and its performance far exceeds that of the 28.8mm 2-pole motor) 3. Built-in 13 -size blades, processed by precision CNC 4. Built-in 3 18650 power batteries (the capacity of a single battery is 2500MaH), long-lasting (the highest level can last for about 15 minutes) 5. Using 30A ESC, low heat generation; maximum power 150W, strong performance Support type-c fast charging protocol Supports stepless speed adjustment function, which can adjust any wind speed. Press and hold to start and release the button to stop.
