@codl I use the skullnco Jumpgate dock (second one, actually, because they had to update it for OLED compatibility) and it works with any power source that gives enough current (not sure what the limit is but it runs off of a USB-C port)
re: network adapters any old one will probably work, but be aware that a USB-2 one will be limited below gigabit speeds which can be annoying for downloads
@codl yeah it definitely has to do some funny stuff, but the dock still works with my iPad so it's also a generic USB-C dock which is really funny
only issue is some early/cheap docks can overload the switch's internal power regulator and fry it, but I think the more well-known sellers have all adjusted their designs by now
