CFIKTE Ultrasonic repellers Drives mouse, Rodent Repellent for car Engines,Used 12V Conventional Battery Power Supply, Easy to Install and use.

Using modern and latest biological concepts and scientific methods to generate specific ultrasound waves, stimulating the nervous and auditory systems of pests such as mice, causing discomfort and escaping from the covered area. The white LED light is flashing. The white LED flashing inside the car has a more frightening effect.  Powered by a 12V conventional car battery, there is no need to use an additional power source, making installation and use convenient. Reverse connection protection function.

If the battery voltage is too low (below 9.2V), the product will emit an alarm sound, indicating that the voltage is too low. At this time, it will no longer work to prevent battery power loss and protect the battery. After the battery voltage is restored, the product will automatically stop alarming and enter standby mode.  Variable frequency output. The product uses a sweep frequency output and a fixed frequency output, and the output time also varies intermittently, reducing the hearing resistance of mice and making it easier to work.  Vibration detection. This product has a vibration detection function. When the car starts, it will drive the product to vibrate. When the product detects this situation, it will stop working. At this time, pests such as mice will not harm the car and reduce power consumption.
