The UGREEN CM511 5-in-1 USB-C Hub is aimed at laptop users who need display output and several USB peripherals from one compact adapter. It combines HDMI, pass-through charging and three USB-A ports, making it a useful travel or desk companion for modern USB-C notebooks. The HDMI connection supports output up to 4K at 30Hz on compatible systems. That is well suited to office monitors, presentations and general desktop extension where smooth 60Hz gaming is not the priority. Three USB-A 3.0 ports provide up to 5Gbps data transfer for flash drives, portable SSDs, keyboards, mice and other accessories. A dedicated USB-C Power Delivery input supports power adapters up to 100W. The actual charging power delivered to the laptop depends on the host device, charger, cable and power reserved by the hub itself, but the feature allows users to keep a notebook powered while the other ports remain in use. The most important compatibility check is the laptop's USB-C port. HDMI output requires the host port to support video, while pass-through charging requires USB Power Delivery support. The USB-C PD socket on the hub is intended for power input and should not be treated as a second data or display port. For users who want one small adapter to handle a monitor, charging and everyday USB accessories, the CM511 offers a balanced feature set without the size or cost of a full workstation dock.
