A Simple, Plug-and-Play Connection with Full Parking Mode Support

The IROAD OBD-II Power Cable (IM-300) is designed to provide a simple, plug-and-play solution for seamlessly powering dash cams whether the vehicle is on or off. It automatically switches between Standard recording mode (when the vehicle is on) and Parking Mode (when the vehicle is off). This can be changed through the S and P switches on the cable, with S only allowing Standard power draw when the vehicle is on, and P allowing both Standard and Parking Mode functionality. Its user-friendly design eliminates the need for complex installations, allowing even those without technical expertise to easily connect their dash cams.

Improved Version, Wider Compatibility

The IM-300 is compatible with all vehicle types, including fuel, hybrid, and electric vehicles. It features an OBD connector switch that allows users to toggle between general and EV modes.
With the ability to support both 12V and 24V batteries, the IM-300 is even more versatile, allowing compatibility with larger vehicles such as commercial trucks and RVs.

With added Stop & Go support, the IM-300 ensures compatibility with Start-Stop engines, which other OBD cables can have issues with.

Works great

Works great. Much better than hardwiring your dashcams.

Can’t return it!

The description for this item on the OBD Power Cable page was "The IROAD OBD-II IM-300 power cable and BlackVue OBD-II power cable are both compatible with various dash cams.” The BlackVue cable was out of stock, so I ordered the IROAD cable to see if it would work. Upon reading the installation instructions, I realized that this cable wouldn’t work with my dash cam. So I thought, no problem, the cable was never plugged in and is still in it’s original packaging, so I’ll just ask for return authorization. BUT, it turns out that BlackBoxMyCar — unlike any other place that I’ve ever ordered from online — does not accept returns of cables. Period. No explanation other than “that’s our policy”. So I’m out $60 for a cable that I can’t use, and BlackBoxMyCar has lost a customer for life!

Works as advertised

I ordered this and installed it in my 2023 Ram 2500 to power an IROAD dash-cam. It was extremely easy and has not caused any problems so far. It's refreshing when something performs precisely as it should.
