It doesn’t matter, USB-C won’t use a voltage that’s in excess of the voltage the receiving device can accept, so even if the cable is theoretically capable of a higher voltage it won’t matter. Just like you can’t overcharge your phone battery anymore, the charging will just stop automatically at 100%.
The switch cable won’t carry data which is odd, but it won’t break your phone and you probably don’t need data most of the time anyway.
No, this is correct. The switch and adaptor use voltages that arent standard to the usb-pd protocol. However, using the adaptor on your phone should be fine as both need to accept the voltages before it switches
I’ve been paranoid to do that since I’d heard that the switch charger is non-standard, but that may just be Nintendo propaganda.
