Tested for 12+ months with zero failures. The default recommendation for any Steam Deck owner who wants TV / monitor output.

Why this dock vs others
The Steam Deck dock market has three tiers:
- Premium ($89-$120): Valve official, JSAUX RGB ModCase
- Value ($35-$50): JSAUX HB0603, similar third-party docks
- Budget (under $25): No-name Amazon listings — avoid
The HB0603 sits at the top of the value tier and matches the premium tier on all functional specs. The gap is build quality (Valve's is heavier and more polished) and brand support (Valve handles warranty directly).
For 90% of users, the value tier is the right purchase.
Confirmed compatibility
I've personally tested the HB0603 with:
- Steam Deck OLED (4K@60Hz on Samsung CRG9)
- Steam Deck LCD
- ROG Ally X (works fully but technically a USB-C hub use case)
- MacBook Pro M-series (works as a portable docking station)
- iPad Pro M-series (4K output works, USB-A ports work)
For devices that aren't DisplayPort Alt Mode capable, the HB0603 won't output video — but USB-A and PD passthrough still work as a generic USB-C hub.
When you'd buy something else
Get the Valve official dock if: You want first-party support, premium build, and don't mind paying ~$50 more.
Get the Anker 555 USB-C Hub if: You travel with the dock and want it to also work with laptops. Slightly better build quality, more compact form factor.
Skip the no-name under $25 docks: Real failure risk. I've personally seen 2 Steam Decks develop USB-C port issues attributed to unstable PD from cheap docks.
