VANTRUE OBD Hardwire Power Cable LED Screen 10ft USB-C

The VANTRUE LED Screen OBD Hardwire Power Cable is a 10ft USB-C hardwiring kit that supplies continuous, monitored power to dash cams with selectable low-voltage cutoffs to protect your car battery.

Designed to keep dash cameras running while your vehicle is parked, this hardwire power cable connects directly to the car battery via an OBD-style plug and provides steady 24/7 surveillance. It includes a visible LED display that shows both the battery's real-time voltage and the cutoff threshold you choose, so you can trust the camera remains powered without risking a dead starter battery. The 10-foot USB-C lead and compatibility with VANTRUE dash cams make it a neat, professional-looking install for sedans, SUVs, and larger vehicles.

How does this hardwire kit keep my dash cam recording while parked?

The cable draws power directly from the vehicle battery through an OBD connection, bypassing accessory sockets that can be turned off. It supports continuous parking-mode operation so motion or impact events are still captured when the engine is off. The integrated LED screen confirms the unit is active and shows battery status at a glance.

• Direct battery connection for uninterrupted power
• 10ft USB-C cable reaches most dash cam mounting positions
• Works with VANTRUE dash cams via bracket power port

What prevents the hardwire cable from draining my vehicle battery?

The unit includes an adjustable low-voltage protection system that automatically cuts power when the battery drops below the preset threshold, preventing excessive discharge. Multiple cutoff options let you match the setting to your battery type and driving habits. The LED display shows both the current voltage and the selected cutoff so you can change settings confidently.

• Settable protections at common thresholds (11.6V/12V/12.4V; 23.6V/24V/24.4V for higher-voltage systems)
• Automatic shutoff to preserve starting power
• Real-time voltage monitoring on the screen

Is this cable easy to install and compatible with my dash cam?

Installation is straightforward: plug the OBD-style connector into the vehicle’s OBD port and route the 10ft USB-C cable to the dash cam bracket power input. It's tailored for VANTRUE dash cams but can also work with other USB-C dash cameras that accept a hardwired bracket supply. The neat OBD plug avoids cutting factory wiring, making it more reversible than a direct-wire kit.

• 10-foot length for flexible routing behind trim and headliners
• Connects into the dash cam bracket’s power port for clean installation
• Non-invasive OBD connection — no fuse tapping required

What does the LED display show and why does it matter?

The LED digital display provides instant feedback by showing the vehicle battery’s present voltage and the chosen low-voltage cutoff. This visibility helps you confirm the system is functioning and lets you change cutoff settings without guesswork. It’s useful during long parking periods or when monitoring battery health in older vehicles.

• Current battery voltage readout for quick diagnostics
• Displays the active low-voltage threshold setting
• Helps detect abnormal battery drain or charging issues

Who is this for? The VANTRUE LED Screen OBD Hardwire Power Cable is ideal for drivers who need dependable parking surveillance without altering factory wiring: commuters, rideshare drivers, fleet vehicles, and anyone who wants continuous dash cam coverage but also needs to protect their car battery. It fits users who prefer a plug-and-play OBD solution with visible voltage feedback and the convenience of a 10-foot USB-C lead.
