What model is this?
This guide is for UGREEN 55733 only. Similar UGREEN hubs and docks can use different video, data and charging controllers.
What must my USB-C host support?
Use a host that supports the connection and operating-system capabilities stated in this model guide.
Can every port reach its maximum at the same time?
No. Displays, USB storage, cards and Ethernet share the upstream host link and available power. Individual port labels are ceilings, not simultaneous aggregate guarantees.
Will it charge my laptop or handheld?
The PD socket is charging input only and does not transfer data. With a compatible 100W charger and cable, up to 85W can reach the handheld/host while power is reserved for dock operation.
Is the wall charger included?
No wall charger is listed in the base package unless your retailer explicitly sells a charger bundle.
Does it support an external display?
The dock uses DisplayPort, not HDMI. A DisplayPort cable and compatible monitor are required. Up to 4K120 requires the host GPU/USB-C display mode, dock, DP 1.4 cable and monitor to support it. Official guidance specifies a DP 1.4 cable no longer than 3m and 28AWG for this maximum.
Can I use it with a Mac?
Compatible functions depend on the Mac model, chip and available port.
Is driver installation required?
The native USB/DP Alt Mode functions are designed to be plug-and-play. Keep the operating system, GPU, USB/Thunderbolt and network drivers current. No DisplayLink claim is made unless explicitly stated.
Is it normal for the hub to become warm?
Some warmth is normal when converting video, network, data and power in a compact enclosure. Keep it uncovered and disconnect it if heat becomes abnormal or operation unstable.
What should I check if a display is blank?
Confirm DP Alt Mode, reconnect power where required, use a qualified display cable, select the correct monitor input, lower resolution/refresh, and update host graphics/USB drivers.
Can I disconnect it while copying files?
Stop transfers and safely eject storage or cards first. Removing the hub during a write can corrupt open files or the filesystem.
