【Smart Automatic Cut-Off】 Never worry about a dead battery again! The system detects voltage levels and automatically disconnects power if it drops below 11.8V for 120s. This preserves enough energy to start your car while preventing drain from aging wiring.

【Anti-Theft & Remote Control】 Secure your vehicle with one click! Use the included remote to cut off power instantly, making it impossible for thieves to start the engine. It effectively eliminates battery drain during long-term parking or storage.

【Safe Driving Protection】 Engineered for safety, the remote function is automatically disabled when voltage exceeds 13.2V (engine running). This prevents accidental power cuts while driving, ensuring the switch can only be operated when the car is parked.

【Energy-Saving Magnetic Relay】 Featuring a magnetic latching design, this switch draws only 3mA in standby mode, placing zero burden on your battery. Rated for 240A continuous current, it ensures stable, heat-free performance for 12V cars, RVs, and trucks.

【Easy Negative Pole Install】 No professional help needed! Designed for the negative battery post (9-17mm), it installs in minutes on most 12V vehicles. Note: Please measure your battery compartment (needs 3.3"x2.4" space) before ordering to ensure fit.
