UGREEN Revodok 11-in-1 (CM681) review – versatile docking station

The Chinese manufacturer UGREEN was founded in 2012 and offers a wide product range that includes chargers, powerbanks and powerstations as well as docks and hubs. After we already tested the Revodok 9-in-1 (CM615) (review ), we now take a look at the recently available and considerably cheaper Revodok 11-in-1 (CM681). This one connects via USB-C and, as the name suggests, offers 11 outputs, including 2x HDMI and 4x USB. How the UGREEN Revodok 11-in-1 (CM681) performs and what you have to do without compared to the more expensive models can be found out in our review.

Scope of delivery

The UGREEN Revodok 11-in-1 (CM681) comes in a compact white box with green accents. On the front, you’ll find a listing of some ports and features alongside a picture of the docking station, and a logo also indicates support for resolutions up to 8K/30 Hz. On the back, UGREEN lists all ports including their number and specifications in a table.

Besides the Revodok 11-in-1, only a user manual is found inside the box. A USB-C cable is permanently connected to the docking station, but a charger for charging the connected device is not included. However, the latter is usually only included in larger and considerably more expensive docking stations.

Design and workmanship

The UGREEN Revodok 11-in-1 (CM681) is mainly made of gray aluminum, only the short sides of the case are made of black plastic. The docking station has an almost square footprint of 71 x 146 mm and is 21 mm high. With a weight of 199 g, it is rather light and is thus also suitable as a USB hub on the go.

The docking station’s ports are located on the long sides of the case. The USB-C type connector cable is ~20 cm long and firmly attached to one of the short sides of the case. On the one hand, this means that the Revodok 11-in-1 does not need a separate cable that can be forgotten on the go, but on the other hand, it cannot be easily replaced if the cable breaks. Unfortunately, UGREEN does not use rubber strips or similar on the underside of the case, which means that the docking station can easily slip and cause minor scratches on the base.

The material quality and workmanship of the UGREEN Revodok 11-in-1 (CM681) can convince in the test. The aluminum case looks high-quality and well-made, only the missing rubber strips on the underside are cause for criticism.

Ports of the UGREEN Revodok 11-in-1

The UGREEN Revodok 11-in-1 (CM681) is connected to the computer via USB-C with the fixed connection cable and provides 11 outputs. On the side usually facing the user, there are a total of 3 USB ports, 2x Type-A and 1x Type-C, with a transfer rate of up to 10 Gbps, a 3.5 mm jack and a card reader with an SD as well as a TF slot (MicroSD).

On the side facing away from the user are the other ports, which include 2x HDMI, 2x USB and 1x RJ45. The supported resolution of the HDMI outputs is up to 4K/60 Hz for HDMI 1, 8K/30 Hz for HDMI 2 and 4K/60 Hz in multi-display mode. The latter also supports AAA, AAB, ABB and ABC modes. The two USB ports are 1x Type-A with a transfer rate of up to 5 Gbps and 1x Type-C for power supply. The latter supports up to 100 W, while the connected notebook is charged with up to 85 W.

The Revodok 11-in-1 thus offers the most important and most frequently needed ports. Furthermore, they are available in sufficient numbers and are up to date. Only a DisplayPort port as an additional video output and alternative to HDMI would be desirable.

Practical test of the UGREEN Revodok 11-in-1

In the practical test, we used the UGREEN Revodok 11-in-1 (CM681) on both a desktop PC and a Lenovo notebook. The following devices were also used, among others:

  • Charger: Anker 65W (USB-C)
  • Monitor: MSI Optix MAG341CQ
  • external SSD: Crucial X10 Pro 2 TB (review)
  • external SSD: Kingston XS1000 1 TB (review)
  • Memory card: SanDisk Extreme microSDXC 128 GB
  • various wired keyboards

The UGREEN Revodok 11-in-1 (CM681) was quickly ready for use in the test, since it doesn’t have a power button it is immediately active after starting the computer. After the first connection, an Ethernet driver was automatically downloaded and installed via Windows Update, a manual installation of further drivers was not necessary. In the further course of the test, the docking station including the connected devices was always recognized quickly and reliably.

This also applies to the MSI Optix MAG341CQ monitor connected via HDMI. Both the multi-display mode AA (duplicate) and the mode AB (expand) worked without problems on both HDMI outputs in the test. We couldn’t test the other modes due to the lack of a second screen.

Furthermore, we performed performance tests with an external SSD and a microSD card to detect possible losses due to the Revodok 11-in-1. As an external SSD, we used the Kingston XS1000 1 TB, which achieves transfer speeds of up to 1,050 MB/s and makes good use of the up to 10 Gbps of the USB ports. In both the AS SSD benchmark and CrystalDiskMark, we only determined very minor performance losses that are not relevant in everyday use. We used a SanDisk Extreme microSDXC 128 GB as microSD card, and did not determine any performance losses compared to other card readers.

We couldn’t find any differences in the Ethernet connection when it came to downloading and uploading. In several tests, we could only record the slightly fluctuating speed here, regardless of the Ethernet port used. In contrast, there were measurable but hardly relevant differences in the ping, which increased by 1 ms due to the docking station.

UGREEN Revodok 11-in-1 test: Conclusion

The UGREEN Revodok 11-in-1 (CM681) knows how to please in the test. The docking station offers an appealing aluminum case, compact dimensions and good workmanship, but rubber strips on the bottom would be desirable. Furthermore, the Revodok 11-in-1 offers a variety of modern and fast ports, including 2x HDMI, 3x USB-A (2x of which 10 Gbps), 1x USB-C (10 Gbps) and 1x RJ45 with up to 1000 Mbps. In practice, we could also achieve the stated transfer speeds, and the differences to the direct connection with the notebook were very small. A card reader and a 3.5 mm jack are also integrated, which means UGREEN probably covers all applications. On the other hand, the lack of a DisplayPort port is cause for criticism, and we would also prefer a replaceable connection cable.

The recommended retail price of the UGREEN Revodok 11-in-1 (CM681) is ~€110. However, coupons have been consistently available since the release, which means that the dock is currently already available for ~€80 (as of 09/14/2023), partly also for €70, which is a good and competitive price. If you are looking for a well-equipped but still affordable dock, you should take a closer look at the Revodok 11-in-1 and the other lineups.
