I’m planning to install an 70mai pro plus A500 dash cam and I wonder if any of you used an OBD2 power cable to power your dash cams?
This should be the links of what I’m getting, hope they can be posted.

neat. I've never seen OBD to USB. But that takes up the OBD port. I wonder if there is a splitter that lets you keep the existing OBD port, so you get your power but can still plug in a scanner when you want to.

Otherwise, it kinda makes more sense to tap off the cigarette lighter to hide a 12v USB converter under the dash. That's what I did for my Qi cradle in the car.

Thanks a lot for your feedback, I will see how long the cable from the dash cam is and decide, still waiting for the camera. Got the OBD plug and that cable is long enough.

Why not use one of the USB plugs in the center console?

I don’t want any cables in the center console, however I’ll see if it’s easier to be done I’ll use your suggestion
Need to check if they are power full time or when the switch is turned on. No sure which it is, think you will want power when switch is on

For parking mode with the OBD II the switch will be on position 1 and that will supply power when the car is parked
