CERRXIAN OBD Power Cable for Dash Camera OBD2 to Type C Adapter Hardwire Charger Cable 24 Hours Surveillance/Acc Mode with Low Voltage Protection 13-40V to 5V 3A (11.5FT/3.5M) (Straight USB C)

Better easier option power cable for dash cam very easy to install no need to hardwire. Work well with multiple brand dash cams, great value

Got this for a dash cam, but wanted to keep the wires hidden and not in a USB or 12v outlet and fighting the wires. I liked this since it has the switch to be keyed power or constant power. There is plenty of length to go from the rearview mirror all the way to the OBD2 port. Installation was easy because of the plug and play. But will ultimately depend on the vehicle being installed on. So far it's worked without a hickup. Will be buying more for my other vehicle as well.

This adapter is awesome, the fuse box in my car is very difficult to access and after trying to figure how to wire into the fuse box I gave up. However, with the OBD adapter there is no guessing, just plug and connect. I like the feature to enable constant monitoring, the adapter will turn off to save battery power should the voltage drops below a predetermined amount. I highly recommend this for its simplicity. Mind that this provides a hardwire connection for power without using the ugly cigarette plug connector.

Bought as an alternative to the 12volt adapter that came with our dash cam. Added bonus it has a toggle switch that allows you to switch between constant and accessory power. The cable is very long so figure out where you'll stow the excess beforehand. The plastic trim tool is easy to use and I was not worried about damaging my car. Cable is plastic encased but thick and durable while small enough to get under trim edges.

This adapter was easy to install and the cable was plenty long enough to reach the dash cam I mounted on the passenger side of my car's windshield. It powered the cam as soon as I turned on the ignition, and I didn’t experience any erratic behavior like spontaneous shutdowns or reboots. The adapter cut power about 20 minutes after I turned off my car, so battery drain was negligible and not a concern. (My remote starter app also monitors my car's vitals, and it never showed any significant battery drain from the delayed shutdown.)The only downside was that parking mode didn’t work with my dash cam. I have a Redtiger F77, which requires voltage from both a 12V constant and an ACC source to enable parking mode. Since this adapter only provides the 12V constant, the camera wouldn’t enter parking mode and instead displayed the message: "Unsupported, please insert the ACC." I suspect this is the same issue others mentioned in their reviews when they said parking mode didn’t work for them either.Because I never had the opportunity to test it, I can’t comment on how well the low-voltage cutoff feature works. Otherwise, it's nice quality and the inclusion of a panel removal tool is convenient. Ultimately, though, I ended up returning it.

This product claims that it will shut off once the battery level reaches 11.6 volts to prevent damage and drainage to the car battery. Teice this thing happened to me where my battery died and can’t get it to jump start so I can go on with my day. I had to huy bew battery for both my cars. Caution to those who wants to use this product, it will drain your battery.

I have bought this to avoid tempering the fuse box and wasting off time! It works perfectly. It has a switch to turn it On/Off as you wish. I would recommend it for people unnecessarily don't want to mess with their car’s original design.

Works great. This is the 3rd one I have in as many cars and highly recommend it for dash-cam applications. Worry free, peace of mind, easy to install.
