My "favorite" are these pepper grinders, milk frothers etc that have a usb c plug but only work with usb a to c cables since they do not include the two resistors that are needed to enable 900mA on usb c to c cable. And if anyone says cost reduction, SMT resistors are like 0.1 cent or less... Seems just stupid.

The much stupider version of this is devices which will charge the wrong way half the time. Eg if I plug my 16” MacBook Pro into a tiny Nintendo switch lite it will charge the MacBook from the switch half the time which isn’t useful 99% of the time

I just noticed this recently with a USB-C flashlight. It wouldn't charge with a C-C cable but started working when I switched to an A-C cable. Good to know why.

Wow...I was just about to throw out a charger that has both USB-A and USB-C ports. The A ports work to charge a device I plugged in, the C ports do not. I thought it was the charger, I'll have to check some more.

Oh, no...

My cheap IKEA milk frother just broke. I'd been using it for years, with the same AA batteries I put in when I bought it. It doesn't require a lot of power.

If the replacement requires re-charging, especially with a cable that I don't usually have ready to hand, I shall be disappointed.

Huh. I have a device that charges fine with A-C, but only charges in one orientation with C-C. Does this suggest that one of the resistors is busted?
