    • Our take on the Voltage Display OBD Cable

    This is a hardwire power cable that runs a Type-C dash cam straight from the car's OBD port, so the camera keeps recording around the clock for parking surveillance. An LED screen shows live battery voltage and the cutoff you set, and the cable cuts power when voltage falls below 11.6V, 12V or 12.4V on 12V systems (23.6V, 24V or 24.4V on 24V systems). It suits owners of Vantrue-style Type-C cams who want parking mode without splicing into the fuse box. Against fuse-tap hardwire kits it is simpler to install and adds a voltage readout, but it occupies the OBD port and only fits Type-C cameras.

    Best forOwners of Type-C dash cams wanting parking modeDrivers who prefer plugging into the OBD port over fuse-box wiringPeople who want to watch battery voltage at a glance
    Pros

    About the Voltage Display OBD Cable

    This is an OBD hardwire power cable with a Type C USB plug for Type C dash cams. It connects directly to the car battery to supply constant power, so the dash cam can keep recording for 24/7 parking surveillance.

    An LED digital display screen shows the battery's real-time voltage and the set voltage. This lets you monitor whether the battery is operating normally.

    A low voltage protection system automatically cuts power to the dash cam when the battery voltage drops below the value you set. This prevents the dash cam from draining the battery.

    Questions and answers

    Will it work with my dash cam?
    It fits dash cams with a Type-C USB power input, including the listed Vantrue N4, N5, E1, E2, E3, S1 Pro, S2, X4S and T3 models. Cameras with mini-USB or other connectors will not work.
    How does the low-voltage protection work?
    You set a cutoff of 11.6V, 12V or 12.4V on 12V systems, or 23.6V, 24V or 24.4V on 24V systems. When battery voltage drops below that value, the cable cuts power to the camera so the battery is not drained.
    Does it record while the car is off?
    Yes. Wired to the OBD port, it supplies constant power so the dash cam can run parking surveillance 24 hours a day, subject to the voltage cutoff.
    What is the LED screen for?
    It shows the battery's real-time voltage alongside your set cutoff, so you can check that the battery is behaving normally.
    Can I still use my OBD port for diagnostics?
    Not while the cable is plugged in. You would need to unplug it to connect a scan tool.
    Where is the Voltage Display OBD Cable cheapest?
    At Vantrue, for $29.99, as of our latest check.
    What do buyers say about the Voltage Display OBD Cable?
