Highlights
- Two Ultrasonic Outputs Plus Four LED Strobes: A 25 kHz fixed-frequency speaker and a 22-50 kHz variable-frequency speaker provide fixed and changing ultrasonic patterns, while four LED strobes add a visual signal to help deter mice, rats, and squirrels
- Power Each Location Your Way: Use 5V USB power through the USB-C input, a compatible 5-12V vehicle-battery connection, or four 1.5V AA dry batteries to match the power available; AAs are not included, and the device does not charge batteries
- Smart vehicle-Battery Protection: If AA backup installed, the unit switches to AA power vehicle battery below 11.8V, switches to power off when backup battery drops below 3.4V, and restarts when vehicle power recovers; vibration standby limits needless power use and resumes about 90 seconds after vibration stops
- Four Units for Multiple Locations: Divide the pack among compatible vehicle engine bays or separate dry, protected spaces, so you can keep multiple locations set up without moving one device back and forth
- Install for a Clear Output Path: Clean the engine bay, secure units through their mounting holes, keep speaker openings unobstructed, and stay clear of water, high heat, belts, fans, and moving parts; intermittent non-flashing periods can be normal

Detailed Review
The Peepst Ultrasonic Mouse and Rat Repellent 4-Pack is designed to help vehicle owners protect engine compartments and dry storage areas from mice, rats, and squirrels. Combining audio and visual deterrence, each unit emits sounds using a 25 kHz fixed-frequency speaker alongside a 22-50 kHz variable-frequency speaker, paired with four flashing LED strobes.
Power flexibility makes these units practical for various setups. You can power each device via a 5V USB-C input, hardwire it directly to a 5-12V vehicle battery, or insert four 1.5V AA dry batteries. When wired to a vehicle battery with backup AAs installed, the unit automatically switches to AA power if the vehicle battery drops below 11.8V, helping prevent dead vehicle batteries. If backup battery levels drop below 3.4V, the unit shuts down entirely until vehicle power recovers.
Installation is straightforward using the built-in mounting holes. To manage power efficiently, built-in vibration detection places the device into standby mode while the vehicle is in motion and resumes operation approximately 90 seconds after vibration stops. Intermittent non-flashing LED periods are part of normal operation, and the set of four lets you cover several engine bays without moving hardware around.
Keep in mind that these devices require clean, dry mounting areas away from water, high engine heat, belts, fans, and moving parts. The speaker openings must remain unobstructed to project sound clearly. Additionally, AA batteries are not included in the package, and the unit does not charge installed batteries when plugged into external power.
Verdict: This 4-pack is an ideal solution for drivers and homeowners who want flexible, automated rodent deterrence across multiple vehicles or protected dry areas. It offers dependable battery protection and versatile power options right out of the box.
