Whether or not this is the case, Nintendo makes it very clear in their warranty that using an unauthorized charger is not covered. They definitely did not intend for it to be a universal port.

And in a year or two I expect that clause will be found to be unreasonable by the ACCC (Australian consumer protection body) and Nintendo will end up getting fined for it.

Their website says that it uses USB-C for charging and the charging port accepts stock USB-C cables, it's not even remotely reasonable to bury within the warranty a statement which says "oh, by the way the device cannot accept USB-C cables -- if you use a made-to-spec cable that fits in the port, no warranty for you!".

The problem is that most consumers don’t read those warnings. And the “reasonable person” would assume that any USB-C cable would work if the USB-C-like receptacle mates with their USB-C cable.

Why would nintendo warranty try to cover scenarios entirely out of their hands? Just because the other guy claims they've produced a usb-c charger doesnt mean they actually did it correctly (which is apparently the case with these docks)

If you shove 9V into a 5V device, bad things will happen, regardless of Nintendo is anti-standard or not

Nintendo say that for all their devices, even the ones that use Nintendo-specific connectors.

I bricked a switch using my macbook charger. It's poor design in the switch to accept a USB cable that can potentially zap the device.

You should look for a lawyer who would take it on contingency and sue. Sounds like a great class action. You often get more money as a class representative rather than just a class member.

They put USB-C on the box. They screwed up the design. They should be forced to have a recall, or extend the warranty.
