I’d get this instead: JSAUX Docking Station Compatible with Steam Deck/ROG Ally, 5-in-1 Steam Deck Dock with HDMI 2.0 4K@60Hz, 100Mbps Ethernet, Dual USB-A 2.0 and 100W USB-C Charging Port for Valve Steam Deck-HB0602 amzn.eu/d/c71hbV8

It’s a fairly well known dock for the Deck, and seems (based on feedback on Reddit) that it’s more reliable than the official one if anything.

That was my conclusion from research, so I’ve got it and it’s worked flawlessly for several months.
