Isn't the use of USB-C promotion without at minimum basic USB compatability disallowed?

I have a few devices which have a USB-A to barrel plug, but they do not advertise anything and afaik that is perfectly fine. And they also only work with a normal USB charger, not the fancy ones.

What?

_reads on_

Turns out, he uses a specific ESP32 breakout board (AFAIK a Lolin one) that includes a charging circuit for a 1S battery. It's a really nice board, but to say that ESP32 includes a charging circuit is wrong, for anyone else curious.
