Maybe this is only 9V and is QC but is providing more current than it should for QC. I think USB PD would use 12/18V for 24W.
Maybe a USB Type C output would be preferable? After all, it is probably not for a dashcam, no dashcam needs 24W of power!
for 24V power input 18V or 20V is OK, for 12V car a buck converter can only output MAX 12V while driving. (0.5V pressure drop on 13.X V generator)
