I have one connected to my Television, but it’s a hassle for games to unhook for games I want to play on the monitor for better latency like rhythm games.
I had heard of some third party ones potentially damaging switches back in the day, and wondered if they have improved since then.
Genki themselves have been the ones to identify the shoddy implementation of USB-C PD by Nintendo: https://www.reddit.com/r/NintendoSwitch/comments/ckaiiv/an_engineers_pov_on_the_3rd_party_dock_switch/
And while Genki addressed the specific issue of power switching and cross signaling with that one specific chip, they didn’t address the USB-C protocol errors the Switch reportedly has. Having a charger physically able to output more than 18W has a residual risk of frying the switch, since the switch is not guaranteed to negotiate PD correctly.
I know this is an emotional topic coming down to either “I never had my switch bricked!” vs. “My switch was bricked by wisps!” and I don’t really care what you put into your switch. But if one would want to be safe, only the original charger/dock is guaranteed to work as expected.
