USB-C hub UGREEN CM800 9-in-1 — DisplayPort 4K@120Hz, 3×USB 3.0, USB-C PD passthrough, Gigabit RJ45, SD + microSD

UGREEN CM800 is a compact 9-in-1 USB-C hub that expands a single USB-C port into multiple useful interfaces: DisplayPort video output supporting up to 4K at 120 Hz, Gigabit Ethernet, SD and microSD card readers, three USB Type-A ports and a USB-C PD passthrough for charging. The hub is foldable with an adjustable angle and includes a detachable USB-C cable for easier transport and desk organization, making it suitable for laptops, tablets and handheld consoles that use USB-C.

Advantages

The hub delivers high-resolution DisplayPort output for smooth video at up to 4K/120 Hz while also offering wired Gigabit Ethernet for low-latency, stable network access. USB 3.2 Type-A ports provide up to 10 Gbps transfer speeds for external drives and peripherals, and the SD/TF card reader supports transfers up to 104 MB/s. Built-in PD charging up to 100 W allows you to power or charge compatible laptops and devices while using the hub. The foldable design with anti-slip silicone and a detachable cable increases mobility and convenience without blocking device ventilation.

Suitable for

• Connecting external displays for gaming or video editing (DisplayPort 4K @120 Hz)
• Wired network connection for streaming, gaming or remote work (Gigabit RJ45)
• Fast file transfers with external SSDs and USB peripherals (USB 3.2 Type-A up to 10 Gbps)
• Photographers and content creators using SD or microSD cards
• Charging and powering devices while expanding ports (PD up to 100 W)

When it may not be suitable

The hub requires a host device with a USB-C port that supports video output and/or Power Delivery for full functionality; older laptops without USB-C or with limited alternate mode support may not provide all features. Very specific enterprise networking setups that require advanced managed switch features or nonstandard network protocols may need a dedicated network adapter instead of a general-purpose hub.

Key specifications

• Video output: DisplayPort up to 4K at 120 Hz
• Ethernet: Gigabit RJ45 (1000 Mbps)
• USB ports: 2 × USB 3.2 Type-A (10 Gbps), 1 × USB 2.0 Type-A
• Card reader: SD and microSD (TF) up to 104 MB/s
• Power delivery: USB-C PD passthrough up to 100 W
• Design: Foldable, adjustable up to 180° with anti-slip silicone
• Simultaneous connections: supports up to 9 devices

How to use

Connect the detachable USB-C cable from the UGREEN CM800 to a USB-C port on your laptop, tablet or compatible handheld console. If you need an external display, attach a DisplayPort cable from the hub to your monitor. Plug in wired Ethernet for stable internet, insert SD or microSD cards into the appropriate slots to transfer photos or video, and attach USB peripherals or external drives to the Type-A ports. If charging the host device is required while using the hub, connect a USB-C PD charger to the hub’s PD passthrough port.

What to consider before purchase

• Host device must support USB-C alternate mode for video output to use DisplayPort
• To charge a laptop through the hub, ensure the host accepts PD passthrough and the charger provides adequate wattage
• Check device compatibility with handheld consoles or tablets for physical fit and ventilation clearance

Usage recommendations

For best results, use a high-quality DisplayPort cable for 4K@120 Hz output, a Cat6 or better Ethernet cable for Gigabit performance, and a PD charger rated for your laptop’s power needs. Ensure the host device’s USB-C port supports the features you require (video, power delivery) before relying on the hub for full functionality.
