VIOFO OP100 OBD-II Power Cable

Power a compatible VIOFO dash cam from the vehicle’s OBD-II port without tapping the fuse box. The OP100 bundle includes the adapter and your selected camera cable, with a parking timer and low-voltage cutoff to manage the power supplied after parking.

OBD-II Connection

Parking Timer

Two Cable Choices

Voltage Cutoff

Separate USB-C Port

Choose the camera cable before ordering

The USB-C bundle supports the listed A329S/A329, A229, A119M Pro, A119 Mini 2, VS1, A139, T130 and WM1 models. The Mini-USB bundle fits A119 V3 and A129 Duo, Plus and Pro. For example, the A229 Plus 2CH uses the USB-C choice; the A119 V3 uses Mini-USB.

Each bundle contains one camera cable, not both. Use that dedicated parking cable from the adapter’s USB-A dash cam port. The separate USB-C output is for a mobile device; it is not a substitute for the camera’s parking-mode cable.

Set the timer and test parking mode

Choose 3 hours, 24 hours or continuous power with the timer switch. The separate ON/OFF switch controls the supply. Enable a supported parking mode in the camera, then test the transition after turning the engine off. OP100 uses the vehicle’s voltage behavior to signal parking mode, so the presence of an OBD-II socket alone does not confirm vehicle compatibility.

The cutoff is fixed: below 12V on a 12V system, or below 24V on a 24V system, the adapter shuts down within 90 seconds. It does not have selectable 11.8V/12.4V thresholds. Continuous mode runs until power is disconnected or the voltage cutoff is reached.

Route the cable and keep the diagnostic port accessible

Use the vehicle manual to locate the OBD-II port, usually beneath the dashboard. Check that the adapter and cable clear the pedals, steering and trim before fitting the fasteners. Route the camera lead using the vehicle’s airbag guidance, and get installation help if the route is uncertain.

The adapter occupies the diagnostic socket, so unplug it when the port is needed for service or a scan tool. It supplies power rather than reading vehicle diagnostics. Do not select it for a hybrid or EV, even if that vehicle has a similar connector.

Frequently Asked Questions

Can I use OP100 in a hybrid or electric vehicle?

No. VIOFO specifies gasoline and diesel vehicles only. Hybrids, plug-in hybrids and EVs are excluded even when they have an OBD-II port.

Should I choose USB-C or Mini-USB?

Match the exact camera to the list in Specifications. A229 models use the USB-C parking cable; A119 V3 and the listed A129 models use Mini-USB. Contact us for an unlisted camera rather than relying only on the plug shape.

Does this bundle include the parking-mode cable?

Yes. Both offered bundles include the OP100 adapter and one selected camera cable. You do not receive both USB-C and Mini-USB leads.

Will it guarantee that my vehicle battery cannot run down?

No. The camera consumes vehicle battery energy while parked. The low-voltage cutoff limits further draw once its threshold is reached, but battery age, charge, temperature and other vehicle loads still affect starting.

Can I change the cutoff voltage?

The published OP100 thresholds are fixed at below 12V or 24V for the corresponding vehicle system. The adjustable switch sets the parking timer, not a choice of 11.8V and 12.4V.

Why does the camera turn off instead of entering parking mode?

Check that the correct OP100 parking cable is connected and a supported parking mode is enabled in the camera. A timer expiration or low-voltage cutoff can also stop power. Vehicle standby voltage affects detection; follow the camera and OP100 instructions.

Can I use the USB-C output to power the camera?

Use the dedicated USB-A output with the selected parking-mode cable for the dash cam. The extra USB-C port is provided for mobile devices and does not replace that connection.

Can a diagnostic scanner share the same port?

The OP100 occupies the OBD-II socket. Disconnect it when that socket is needed for diagnosis or service. This adapter is a power accessory, not a vehicle code reader.

Will OP100 work with every gasoline or diesel vehicle?

Confirm the exact vehicle and port wiring. Gasoline and diesel vehicles still need a diagnostic port and voltage behavior that suit OP100. Older vehicles and some commercial vehicles can use different diagnostic standards despite a familiar-looking socket. Check your model and year, then test the transition from driving to parking recording.

How does OBD parking detection differ from hardwiring?

Detection methods vary by cable. An OBD cable may use voltage changes, motion or timers, and some generate an ignition signal for the camera. A three-wire hardwire kit connects directly to the vehicle’s ignition circuit. Follow this cable’s instructions and test driving and parking recording after installation.
