Yes, I use that one too with a laptop to run forscan. It also works with your phone for track apps for engine data etc. Overall its the best option IMHO.
? You sure about that idea ? OBD is always powered, it'll discharge your battery.Is there any scan tool (OBD rig) that also provides an USB port to power my dash cam? That would be a cool feature but I cannot find one.
There are power cables like this https://www.garmin.com/en-US/p/735279 where you can set the power-off timing and they disconnect the cam. But it wont allow to connect anything to the OBD port.? You sure about that idea ? OBD is always powered, it'll discharge your battery.
