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.
30W GaN sounds like a sure way to brick your switch when powered off.
Well it’s a good thing the max draw of a switch is 18W, and this device has a specific 9V power profile for the switch. The 30W is there to support devices with a faster power delivery spec (such as the Steam Deck).
