VIOFO OP100 OBD‑II Constant Power Cable (Type‑C) is a plug‑and‑play power solution that supplies your dash cam directly from the vehicle’s OBD‑II port—no fuse box wiring required.
It’s an ideal choice if you want easy installation, a cleaner interior with fewer visible cables, and the ability to use parking mode without a traditional hardwire kit.

OP100 provides constant power even when the car is turned off, and helps protect your car battery with low‑voltage protection: if the voltage drops too low, the cable automatically cuts power.
It also features an ON/OFF switch and a parking recording timer (3h / 24h / ∞), allowing you to control how long power is supplied in parking mode.

As a practical bonus, OP100 offers dual output ports: a USB‑A port (prioritized for the dash cam) and an additional Type‑C port for charging a phone or another device.
