Not all USB ports are created equal, indeed. There's a lot of false
advertising and just faulty equipment being pumped out of China. I got so
sick and tired of odd charging rates and the like, that I picked up this USB
Power Meter <https://smile.amazon.com/gp/product/B073R7YRM9/> from Amazon
to validate that I was getting what was advertised. Definitely overkill for
your needs, but I also use it to troubleshoot external devices and hubs
being connected to computers, so it's been very useful.

All that said, I've had very little trouble with the traditional USB 2
series of ports and cables. Most of the trouble has been with the newer USB
C-based ports and/or cables and the much higher power they can support. I
haven't really seen any hardwired USB C-based ports for 12V applications,
but have for 24V.
