OTOH we have tons of crazy non-usb transformers with all kinds of different plugs that might or might not plug into devices they're meant for.
It seems like somehow we're used to the idea that this particular plug will only work with the device that came with it, but we assume that USB-A is USB-A. I know I do.
This does make me wonder about the USB adapter I got with my dash cam. The documentation says all over the place to pretty please with sugar on top use our adapter. I'll have to stick a meter on it. [Edit: 5.1v.]
It's likely that they are trying to avoid support calls from users plugging into whatever USB port is on their dash that might not supply enough current, or is intended for media/AA/Carplay and forcing the camera into interfacing with the infotainment system.
