Multiple built-in safety features, including spark-proof connections, reverse polarity protection, and temperature compensation, provide peace of mind during every use. Advanced Safety Circuit Protection with SafeGuard circuitry prevents potentially dangerous back-feeding from your vehicle's battery to the jump starter, ensuring safe operation while protecting both power sources and your vehicle's sensitive electronics.
