Improved reliability: The enhanced interface increases stability and minimizes reboots and deformation at high temperatures, so most dashboard and rear view cameras operate reliably. Uninterrupted monitoring: Provides 24-hour power to your dash cam even when the vehicle is not in use. Connect the hard wiring kit to your car battery or fuse box for continuous recording. High safety standards: The built-in precision switching power supply converts 12V (24V) to 5V, with safeguards to prevent overcurrent and overheating. Comprehensive compatibility: Compatible with most models from 12-24V and adapts to almost all automotive USB devices, including rear-view mirror cameras, GPS navigation devices, and radar detectors. Use scenarios: - Personal vehicle parking mode: Power your dash cam continuously so footage is captured during long stops or overnight parking. - Fleet or service vehicles: Centralized power to dash cams and USB devices via the fuse box for reliable operation across multiple vehicles. - Truck, RV or SUV setups: Supports a range of USB devices (GPS, cameras, radar detectors) from a 12-24V supply for flexible installations.
