Ultrasonic Car Mice Repeller Ultrasonic Pest Repeller Aluminum Alloy Mice Repeller Electronic Mice Car Deterrent Humane Harmless Mice Repeller Features: TWO WORKING MODES: Its ultrasound has two working modes: one is mice repellent, and the other is strong mice repellent. The first one means ultrasonic frequency changes automatically and slowly in 120 seconds. And the second can fast produce powerful and random blasts of LED strobe lights and ultrasounds in 130 seconds to keep mice and pests away from your beloved car. AUTO ON/OFF: When the car works, detecting the voltage of the generator, the product stops working automatically. When the car stops, detecting the voltage of the battery is lower than that of the generator, it enters the working mode in about 120 seconds (the 120 seconds is to prevent the car from burning out the internal components of the product as the temperature is too high just after the car stops), so this can prolong the service life of the product. PREMIUM-QUALITY MATERIAL: The ultrasonic car mice repellent is mainly made of high-quality aluminum alloy material, which is anti-corrosive and durable, serving you for a long time. HUMANE & SAFE: The mise repellent device, harmless and humane, is designed and developed for pest-sensitive frequency, whose sound can not be heard by human beings. DUAL BATTERY SUPPLIES: When the car stops, it runs on battery power; while it is powered by a generator when the car works.
