Use Cases & Applications

For Students

Transform your thin-and-light laptop into a complete study station. Connect the UGREEN CM274 to add an external monitor for split-screen note-taking during online lectures, plug in a wired mouse and keyboard for comfortable typing, and use the Ethernet port for stable connections during timed exams.

The SD card reader simplifies transferring photos from DSLR cameras for photography courses or design projects. Import hundreds of images in minutes without draining your laptop battery through wireless transfers. The hub’s compact size fits easily in backpack pockets for moving between dorm rooms, libraries, and study groups.

Charge your laptop through the hub while using all ports, keeping your workspace organized with just one cable to unplug when heading to class. The 100W power delivery supports power-hungry laptops like MacBook Pro 16″ at full charging speed.

For Business Professionals

Create instant workstations in hotel rooms, client offices, or coworking spaces. The CM274 connects to room TVs or conference displays via HDMI for presentations, while the Ethernet port provides secure wired connections that avoid public Wi-Fi security concerns.

Connect external storage drives, presentation clickers, and wired peripherals through the three USB-A ports during client meetings. The audio jack lets you use professional headsets for private video calls in shared office environments without disturbing colleagues.

Hot-deskers benefit from the single-cable connection—arrive at any desk, plug in one USB-C cable, and instantly access monitors, network, and peripherals without crawling under desks to connect multiple cables.

For Content Creators

Import footage from multiple SD cards while backing up files to external hard drives through USB ports simultaneously. The hub handles data transfers from cameras and card readers without bottlenecking, keeping your workflow efficient during time-sensitive projects.

Extend your laptop screen to a larger monitor for editing timelines, color grading, or reviewing footage at actual size. The 4K@30Hz output works well for video editing interfaces and photo retouching applications.

For Remote Work Setups

Build a home office setup that connects and disconnects with one cable. Leave the UGREEN CM274 permanently connected to your monitor, keyboard, mouse, and Ethernet cable—when you start work, plug in your laptop with one connection and everything activates instantly.

The Gigabit Ethernet ensures stable video conference connections without the latency or dropouts common with wireless connections. Your microphone and speakers connect through the 3.5mm jack, reducing the number of Bluetooth devices competing for bandwidth.

Technical Considerations

The CM274 requires your laptop’s USB-C port to support DisplayPort Alt Mode for HDMI output to function. Check your laptop specifications if video output is essential—some budget laptops include USB-C ports for charging and data only.

Power delivery provides up to 85W to your laptop because the hub reserves approximately 15W for its own operation. Most ultrabooks charge fully at this wattage, but some high-performance laptops may charge slowly under heavy load.

The hub draws power from your laptop when the PD port isn’t connected to a power adapter. This setup works for basic peripherals but may drain your battery faster. For stationary use, always connect a USB-C power adapter to the PD input port.

Card readers support SD and microSD cards simultaneously, but transfer speeds depend on your card’s rating. UHS-I cards achieve faster transfers than older card standards. The hub doesn’t support CFexpress or other professional card formats.

Important Notes: Some USB-C monitors with daisy-chaining support cannot be used simultaneously with this hub’s HDMI output. Connect monitors through the hub’s HDMI port instead. Nintendo Switch users should note that while the hub physically connects, it doesn’t provide the video output functionality of the official Switch dock. For iPad Pro compatibility, iPadOS 13 or later is required, and some features like Ethernet may need additional configuration in settings.
