VIOFO OP100 USB-C & Mini-USB OBD-II Power Cable

The VIOFO OP100 OBD-II Power Cable is the easiest way to unlock parking mode on your VIOFO dash cam without complex hardwiring. Simply plug into your vehicle's OBD-II port for instant, constant power. Available in both USB-C and Mini-USB variants to fit the full range of VIOFO dash cams, from the latest A329 and A229 series to the proven A119 V3 and A129 lineup. Select your connector type above to ensure the perfect fit for your model.

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.

Please verify that your vehicle meets standard OBD-II specifications before purchasing. If you are unsure, contact our team and we'll be happy to help.

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.

Designed for Modern VIOFO Dash Cams

The VIOFO OP100 is available in two variants to ensure compatibility with the full range of VIOFO dash cams. Select the correct connector type for your model before purchasing.

  • A329 Series (A329S, A329)

  • A119M Pro

Not sure which connector your dash cam uses? Check the power port on your camera or look up your model on the VIOFO website. If you are still unsure, contact our team and we will help you find the right fit.

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.

FAQs

How is this different from a standard hardwiring kit?

An OBD-II power cable is a plug-and-play solution that draws power from your vehicle's diagnostic port. A traditional hardwiring kit requires you to tap into your vehicle's fuse box, which is a more involved installation process. The OP100 is ideal for drivers who want a quick, tool-free installation or the flexibility to move their dash cam between vehicles.

Can I use the OP100 with the VIOFO BP100 battery pack?

No, the OP100 OBD-II power cable and the BP100 battery pack serve different purposes and cannot be used together. The OP100 draws power from your vehicle's OBD-II port, while the BP100 is a standalone external battery pack that powers your dash cam independently. If you need extended parking mode without draining your car battery, consider the BP100 battery pack as an alternative solution.

Will this drain my car's battery?

No. The OP100 has a built-in low voltage protection feature that automatically cuts power to the dash cam if it detects your car battery's voltage is getting too low, ensuring your car will always be able to start.

Where is my car's OBD-II port located?

The OBD-II port is usually located under the dashboard on the driver's side, often near the steering column. Your vehicle's owner's manual will show the exact location.

How do I know whether to buy the USB-C or Mini-USB version?

Check the power port on your VIOFO dash cam. Newer models like the A329, A229, A119 Mini 2, A119M Pro, VS1, and A139 series use USB-C. Older models like the A119 V3, A129 Duo, A129 Plus, and A129 Pro use Mini-USB. If you are unsure, check your dash cam's user manual or contact our support team before purchasing.

Is this compatible with my VIOFO dash cam?

The OP100 is available in two versions. The USB-C version works with newer models including the A329, A229, A119 Mini 2, A119M Pro, VS1, A139, T130, and WM1 series. The Mini-USB version works with the A119 V3, A129 Duo, A129 Plus, and A129 Pro. Make sure to select the correct connector type for your dash cam model.

Can I still use an OBD-II scanner with this cable installed?

This cable plugs directly into your OBD-II port, so you would need to unplug it to use another OBD-II device like a diagnostic scanner. However, for daily driving and parking protection, it can remain plugged in at all times.
