The set of 4 LED propellers is specially designed for DJI Mini 3/Mini 3 Pro/Mini 4 Pro drones. During night flights, the spectacle will be amazing; the drone will look very interesting in the sky and you will be able to see it from a distance. These next-generation propellers are made of nylon and fiberglass, offering excellent noise reduction performance and longer flight time. They are drop-resistant, durable, and have superior stiffness compared to the originals. Connect the USB cable to the propeller's charging port and the other end to a computer or mobile phone charger. The charging time is 50 minutes, and the LED light can be used for 60 minutes. They are easy to install and remove and do not affect normal flight.
