More Stable Output Voltage The vehicle hard wiring kit with built-in precise switching power supply converts 12V (24V) to 5V, ensuring a more stable output voltage.
Low voltage protection: the current output will be automatically interrupted when the voltage drops below 11.6V. Compatible with large and small vehicles to ensure a smooth start.
Input: 12-24V | Output: DC 5V 2.5A 24-hour monitoring and protection against deep discharge.
EASY INSTALLATION - Simple, concealed wiring keeps your car tidy and allows you to connect more devices via the cigarette lighter.
24-hour monitoring: the vehicle-fixed cable set connects to the car battery or fuse box, ensuring continuous power supply for 24 hours. The system remains powered even when the vehicle is switched off. (Note: For an old or weak vehicle battery, disable the 24-hour recording during longer parking times. Continuous power consumption can lower the battery voltage below 11.6V and prevent vehicle starting.)
