UGREEN CM512 7-in-1 USB-C Multifunction Adapter (90568)
The UGREEN CM512 USB-C adapter converts a single USB-C port into seven simultaneous connections: Gigabit Ethernet, 4K HDMI display output, 100W pass-through charging, dual USB-A 3.0 data ports, and independent SD and Micro SD card slots. It is designed for laptop and tablet users whose devices provide limited ports — particularly MacBook, Dell XPS, Surface, and iPad Pro owners who need wired network access alongside peripheral connectivity. Additionally, the aluminium housing and 20 cm integrated cable make it compact enough to carry daily without adding meaningful weight to a laptop bag.

Use Cases and Applications
Wired Networking in Port-Limited Laptops
Ultrabooks and MacBooks no longer ship with RJ45 ports, yet many corporate networks, hotel rooms, and co-working spaces offer faster and more reliable wired LAN than Wi-Fi. The UGREEN CM512 plugs into a single USB-C port and immediately provides a 1 Gbps Ethernet connection alongside display output and peripheral access. Consequently, users gain a full desk setup without carrying multiple single-function adapters.
Extended Display for Presentations and Remote Work
The 4K HDMI output works in both Mirror and Extended modes, making it straightforward to connect a laptop to a projector, conference room display, or external monitor. HDR10 support additionally benefits users who connect to HDR-capable screens for colour-accurate design or video review work. The 4K@30Hz ceiling suits most productivity and presentation scenarios; however, users requiring 60Hz refresh rates at 4K resolution should review the 60515 variant instead.
Media Ingest and Photography Workflows
Photographers and content creators returning from shoots can insert an SD card and a Micro SD card simultaneously, importing from both at ~90 MB/s while the laptop charges at up to 95W through the PD port. An external hard drive connected to a USB-A 3.0 port receives transferred files at up to 5 Gbps in parallel. As a result, the ingest, backup, and charging workflow runs through one compact device.
Travel and Portable Office
At 119 g with an integrated cable, the CM512 travels easily. It covers the four most common port gaps for laptop users — LAN, display, USB-A peripherals, and card reading — without requiring separate adapters for each function. Furthermore, the aluminium housing dissipates heat effectively during extended use.
