## Overview

It safeguards your car battery by shutting off at 11.6V and supports a wide voltage input range (8V-36V). Compatible with most vehicles through a 3-pin OBD interface, it also charges other USB devices, making it a versatile, professional-grade solution for uninterrupted in-car surveillance.

## Description

Working Mode: Mode “O”: ACC mode, when your car ACC is off, the OBD power cable will also power off after 5 minutes. Mode “—”: Surveillance mode, when you car ACC is off, the OBD power cable will keep working until detecting the car battery voltage is at 11.6V(low voltage),it will power off after 30 seconds. The low voltage protection for mode “—” protect your car from running out the battery, enable you have enough voltage to start the car for next driving. Attention: 1. Please note that the OBD power cable is only working for dash cams or other devices which range from 8V-36V,other voltage range is not supported. With the step-down function, the voltage will be converted to 5V output. 2.
