Can’t say I’ve done extensive research, and Nintendo would be the first company I would assume would ignore standards, but my understanding is that any half decent charger has a sort of power negotiation to prevent such issue. I suppose if you have some cheap dollar store USB-C chargers laying around it might be risky if they too ignore the standards.

That said, I did have a USB-C PD 65w charger fry a laptop. It was, for sure, the charger screwing up though, I even had warning signs I completely ignored. I miss that laptop, it was a good laptop.
