The Easiest Way to Power Your Dash Cam
The VIOFO OP100 OBD-II Power Cable is a plug-and-play parking mode solution that connects directly to your vehicle’s OBD-II diagnostic port. This eliminates the need for complex fuse box hardwiring, making it the best OBD-II power cable for drivers who want a quick, clean installation.
The OBD-II port is a standard feature on nearly all vehicles manufactured for the US and Canadian market since 1996. Installation takes just a few minutes: plug the cable into the port, route the wire along your headliner, and connect it to your dash cam. No tools, no fuse taps, no electrical knowledge required.

Universal Vehicle Compatibility
The VIOFO OP100 is compatible with most OBD-II (16-pin) vehicles manufactured since 2010, including gasoline, diesel, hybrid, and most electric vehicles. The OBD-II standard uses a unified 16-pin connector with consistent physical shape, pin definitions, and power protocols, so the OP100 works seamlessly across nearly all modern passenger vehicles regardless of fuel type.
The cable features built-in low voltage protection that constantly monitors your vehicle’s battery. If the voltage drops below a selectable threshold (11.8V or 12.4V), the cable automatically cuts power to the dash cam within 90 seconds. This intelligent safeguard ensures your vehicle will always start, even after extended parking mode sessions. For drivers who need longer parking protection without any risk to their vehicle battery, consider the VIOFO BP100 battery pack as an alternative standalone power solution.

Unlock Intelligent Parking Mode
To protect your vehicle when it’s parked, your dash cam needs a constant source of power. The OP100 provides this continuous power, allowing your VIOFO dash cam to enter its intelligent parking surveillance modes. Once connected, your camera can automatically monitor for motion and impacts, recording and saving footage of any incidents that occur while you’re away. This is essential for capturing evidence of hit-and-runs, vandalism, or other parking-related events. This plug-and-play design is ideal for drivers who are not comfortable with traditional hardwiring, or for those who want the flexibility to easily move their dash cam between vehicles. The cable includes a simple ACC/constant power switch, giving you full control over whether the dash cam records only while driving or continues into parking surveillance mode.

Smart Power Management and Battery Protection
The OP100 is engineered with your vehicle’s battery health in mind. It features built-in low voltage protection, which constantly monitors your car battery’s voltage level. If the voltage drops below a preset threshold (11.8V or 12.4V), the cable will automatically cut power to the dash cam. This intelligent feature prevents the dash cam from ever draining your vehicle’s battery, ensuring you can always start your car. Additionally, the cable includes a timer switch with three settings (3 hours, 24 hours, or continuous), allowing you to control how long the dash cam records after you park. This gives you complete control over your parking surveillance and power consumption, providing both security and peace of mind.
A Clean and Discreet Installation
Achieve a professional, factory-installed look without the effort. The OP100 OBD-II cable allows you to neatly tuck the power wire along your vehicle’s headliner and A-pillar, keeping it completely out of sight. This eliminates the clutter of a power cord dangling from your rearview mirror to the cigarette lighter, keeping your dashboard tidy and your view unobstructed. By using the OBD-II port, you also free up your 12V cigarette lighter socket for other essential devices like your phone charger or a GPS unit. It’s the perfect solution for maintaining a clean, organised, and functional vehicle interior while ensuring your dash cam is seamlessly integrated for maximum protection. {“__shgImageV2Elements”: { “uuid”: “s-d0b35a67-06ea-4572-8403-c556f549d89b” } }
