USB-C Hubs Decoded: How to Pick the Right Ugreen Dock for Your SetupSingle monitor, dual monitor, MacBook or PC? Here's the no-nonsense guide to choosing a Ugreen USB-C hub.Hub vs dock: what's the difference?A hub is small, bus-powered and bolts onto your laptop port — perfect for travel. A dock is wall-powered, sits on your desk, and turns one cable into your full multi-monitor + Ethernet + audio setup.Single 4K vs dual 4KIf you want two external 4K monitors at 60Hz, you need DisplayLink or Thunderbolt 4 — which Ugreen offers in its higher-end Revodok range. For single 4K, any standard USB-C hub will do.Power passthrough is non-negotiableMake sure your hub supports at least 85W power passthrough so it can charge your laptop while connected. Anything less and you'll be stuck topping up overnight.
