Dash Camera OBD Hardwire Kit OBD Power Cable - 24h Parking Protection

In this review the Dash Camera OBD Hardwire Kit is evaluated for drivers who want uninterrupted dashcam power without splicing into vehicle wiring. The bottom line: this OBD power cable is for people who need a simple, reversible hardwire solution that supports Type-C and micro USB dash cams and offers intelligent low voltage protection to avoid a dead battery. The reviewer found installation straightforward through the OBD port and especially useful for 24 hour parking surveillance or ACC-only operation, with a clear behavior change between the two modes.

Key Features

• Wide input range: Accepts 11.6V to 36V input so it works across most gasoline and diesel cars and trucks (not for electric vehicles), avoiding compatibility surprises.
• Stable output: Provides a DC 5V/3A output suitable for Type-C dash cams and many micro USB models, keeping recording stable while driving.
• Dual modes: Offers a 24 hour parking monitoring mode and an ACC mode that shuts power off 20 minutes after engine stop, giving control over when the camera draws power.
• Low voltage protection: Automatically cuts output when vehicle battery drops below 11.6V to protect starting power and prevent over-discharge.
• Easy installation: Plugs into the vehicle OBD connector for power without altering wiring, with a 3.5 m (11.5 ft) cable and an L-shaped Type-C plug to fit tight spaces.
• Hidden routing: Long cable and included organizers let users tuck wiring under trim and roof lining for a clean interior appearance.

Who It's For

This product is best for owners of conventional gas or diesel cars and trucks who want a no-fuss hardwire option for dash cams, GPS or radar units that use Type-C or micro USB power. Fleet vehicles, commuters parking on street overnight, and owners who want an easy reversible install will appreciate the OBD plug approach and the 24 hour parking mode.

It is not for electric vehicles, and buyers who require programmable timers beyond the two built-in modes or professional hardwire kits that integrate with vehicle CAN data should look elsewhere. Also, if a dashcam requires more than 5V/3A power or non-USB power delivery, this cable will not meet that need.

Pros & Cons

Pros

• Simple plug-and-play installation via the OBD port avoids cutting factory wires.
• Intelligent low voltage cutoff at 11.6V preserves battery health and ensures start power.
• Two operation modes let users choose continuous parking monitoring or ACC-only power for flexibility.
• Long 3.5 m (11.5 ft) cable and L-shaped Type-C plug help route and connect in tight dashboards.

Cons

• Not compatible with electric vehicles, which limits applicability for EV owners.
• Mode switching requires unplugging and reinserting the OBD adapter, which is mildly inconvenient.

Our Verdict

The OBD Hardwire Kit is a practical, cost-effective way to power Type-C and micro USB dash cams without modifying vehicle wiring. It is a good value for drivers who need 24 hour parking surveillance or a simple ACC-only option, and the low voltage protection reduces the risk of a dead battery. Those with electric vehicles or specialized power requirements should consider alternate hardwiring solutions.

Frequently Asked Questions

Will this work with my dash cam?
It powers dash cams that accept USB Type-C or micro USB at 5V/3A; verify your camera uses USB power and does not need higher voltage.

Does it drain the car battery when parked?
The cable has an intelligent low voltage cut-off at 11.6V to stop drawing power and help prevent battery discharge during parking mode.

How do you switch between modes?
Change modes by unplugging and reinserting the OBD adapter into the OBD port; the adapter uses this reset to register the new mode.
