UGREEN CM219 (Model #50985) 4-Port USB 3.0 Hub Review

The UGREEN CM219 (Model #50985) 4-Port USB 3.0 Ultra Slim Data Hub promises a sleek, space-saving solution for expanding your USB connectivity. But does it deliver on its promises of speed and reliability? I’ve spent the last few weeks putting this space grey hub through its paces to find out.

The UGREEN CM219 boasts a minimalist design, with its slim profile and space grey aluminum casing making it a discreet addition to any workspace. The short cable length (16cm) prevents cable clutter, while the 4 USB 3.0 ports provide ample expansion for your peripherals. The manufacturer highlights its compatibility with a wide range of operating systems, including Windows, macOS, and Linux, claiming plug-and-play functionality.

In terms of performance, the UGREEN CM219 largely lived up to expectations. Data transfer speeds were consistently fast, easily reaching the advertised 5Gbps speeds when transferring large files between my external SSD and my MacBook Pro. I tested it with various devices including a mouse, keyboard, external hard drive, and USB flash drive—all worked flawlessly. The plug-and-play functionality was a real time-saver, and I appreciated the lack of driver installation. However, as stated by the manufacturer, the hub is explicitly *not* designed for charging high-power devices. Attempting to charge my iPad via the hub resulted in slow, unreliable charging. This is clearly stated in the product description, but it’s worth reiterating for potential buyers.

The hub remained cool even during extended use, a testament to its build quality. I did not experience any interference with Bluetooth or Wi-Fi signals, which was a positive.

I also tested its stability while running multiple USB devices simultaneously, experiencing no dropouts or performance issues. The device did have a slight humming sound, barely noticeable though, when transferring large amounts of data.

Pros:

  • Fast data transfer speeds (up to 5Gbps)
  • Compact and portable design
  • Plug-and-play functionality
  • Sleek, premium design
  • Excellent build quality
  • No noticeable interference with Bluetooth or Wi-Fi

Cons:

  • Not suitable for charging high-power devices
  • Slight humming noise during high-data transfer

Overall, the UGREEN CM219 (Model #50985) 4-Port USB 3.0 Ultra Slim Data Hub is a solid performer, providing a convenient and efficient way to expand your USB connectivity. While it’s not designed for charging, its speed and reliability for data transfer make it a worthwhile purchase for those needing extra USB ports. If you’re looking for a compact, well-built hub for your data transfer needs, I would recommend it.
