If it bears the USB logo, the charger should be standards compliant. The switch charger will charge your devices just fine.

The switch console, however, has a non-compliant USB port, which can be damaged when hooked up to a standard USB-PD charger; the pins can get mechanically shorted. Blame Nintendo for that one.

this is literally the problem with any specification then, because there is nothing stopping anyone from not following the specification for a particular port and just doing whatever the fuck they want.

I could hook a lightning cable up to a car battery, and you'd blame the connector.

Hasn’t done anything like this yet, it works perfect.

I’ve charged my MacBook with all sorts of USB-C chargers with no issues, including from USB power banks (I was never able to charge my laptop from a standard portable external battery before usb-c!).
