for people buying USB c cable extenders without doing some research:
" But the issue of incompatible cables is even more serious. Many companies, including my go-to source, Monoprice, are building USB-C cables of various quality and compatibility. If youre not careful, you can neuter or even damage your devices by using the wrong cable. Seriously: Using the wrong cable can damage your machine! This should not be possible, but there it is.
The problem is that the nintnedo switch DOCKED uses more power than handheld mode, and they switch basically overclocks. If you use an extender, the switch might not get enough power required to work harder, which might damage.
