Accurate power failure monitoring and fast response Builtin sensitivity sensors monitor the circuit in real time, enabling immediate power failure protection. Performance is significantly faster than traditional protection equipment, with an 80 percent faster response. Supports autodetection of incoming power and intelligent assessment of power restoration stability to avoid repeated starting and stopping caused by voltage fluctuations. Easy installation and convenient operation Standard plugandsocket design, plugandplay, no professional electrician required. LED status indicators provide realtime operation feedback: Red light indicates a good connection with the battery; the red display shows the current battery voltage. Blue light indicates connection to the vehicle diagnostic interface; the blue display shows the current. Widely applicable for automotive power protection Automotive battery diagnostic functionality helps preserve memory for automotive computer systems, audio, navigation, air conditioning, and other electronic equipment during battery replacement. Provides temporary power by connecting to the vehicle's onboard diagnostic port to keep electronics powered during battery replacement, reducing the need to power down or reconfigure devices. Vehicle ECU data memory Supplies power to the vehicle ECU during battery replacement to prevent data loss. Eliminates the need to reset vehicle electronics after battery replacement, saving time and effort. Use scenarios Replacing a car battery at home without losing radio presets, navigation data, or climate settings. Servicing fleet vehicles in a workshop, maintaining ECU memory and avoiding reentry of configurations after battery swaps. Incar maintenance or diagnostics requiring continuous power to electronic systems during battery work.
