USB-C hubs confirmed for real handhelds and laptops

A hub is what's left once you drop the Ethernet-plus-video combination that defines a dock: simpler, usually more portable. 102 confirmed: 36 for Steam Deck, 22 for ROG Ally, 10 for Legion Go, and 101 for notebooks. Steam Deck alone accounts for over a third of this category (36 of 102) — a share close to docks (75 of 225) but still behind chargers, where Steam Deck confirmations (38 of 66) come closer to matching notebook coverage than in any other category.

Handheld compatibility here is a per-SKU question, not a brand-wide one. The Anker 341 (A8346) is explicitly documented as incompatible with Steam Deck — multiple independent reports describe DP Alt Mode signal issues on that exact model — while it "works reliably" on Legion Go at up to 85W passthrough. Buying a different Anker hub because "the brand works with Steam Deck" is exactly the assumption that breaks here.

The Anker 553 (A8380) has enough of a following on Steam Deck that the community has designed 3D-printable dock stands specifically to mount it — a sign of a hub that's genuinely become part of people's handheld setup rather than merely being technically compatible.

macOS mirroring shows up in hubs the same way it does in docks. The Baseus Metal Gleam 9-in-1 mirrors identical content across all external monitors on macOS regardless of its 120Hz capability per display — Windows doesn't share that limitation.
