I own a Switch 1, and the other day I wanted to play on the train, but the battery was low. I figured "no problem, I can connect it to my laptop and let it charge off is battery".

Nope. The MacBook Pro started charging off the Switch instead.

I was really excited when I learned that unplugging the cable, waiting some short period of time and plugging it back in, triggers a power-role swap.

I've only tried it out on one occasion, and I'm not clear on the delay, or whether both ends need to be disconnected or only one. I was a little surprised it isn't talked about more.

Is that for a specific device? For standard dual-role USB-C devices they do a negotiation that is partially based on chance which power role they land on (but they can have policy that strongly prefers one role over the other).

Whatever I read made me think it was some sort of standard.

You know more about this than me, so now I think what I stated about unplugging and re-plugging is likely incorrect advice, one step above "turn the cable around" which I think also works enough of the time that people keep trying it and repeating it as a method.
