Why Use the OBD Port?

By tapping into the OBD-II port rather than the cigarette lighter socket, you free up your 12V outlet for other uses and enjoy a far cleaner install. This makes it the ideal solution for dash cam installations, GPS trackers, and any Mini USB device that needs a permanent, always-on or switched power source in your vehicle.

Frequently Asked Questions

Q: What devices is this OBD car power adapter compatible with?

A: This adapter is designed for any device that charges or powers via a Mini USB 5-pin connector, most commonly dash cameras (DVRs), GPS loggers, and early-generation MP3/MP4 players. If your device uses a Mini USB port, this adapter is an excellent hardwire power solution for your vehicle.

Q: Will this OBD adapter work in both cars and trucks?

A: Yes. The wide input voltage range of DC 8–36V means it is fully compatible with standard 12V passenger cars and 24V commercial trucks alike. No special configuration is needed — simply plug it into the OBD-II port and connect your device.

Q: Is it safe to leave this adapter plugged in all the time?

A: The adapter features a 15-second boot delay and multiple built-in protections — including low voltage cut-off (at 11.6V), reverse connection protection, overvoltage, overcurrent, overheating, and short circuit protection with automatic recovery. These safeguards make it suitable for long-term installation, helping to protect both your vehicle's electrical system and your connected device.

Q: How long is the cable and is it enough to hide the wiring?

A: The cable is 3.5 metres (approx. 11.5 feet) long, which is more than sufficient for most vehicles to neatly route the cable along the headliner, A-pillar, or dashboard to your dash cam or GPS unit for a clean, professional-looking installation.
