Question about Ugreen USB C – USB-C

I got the cable for the same purpose. It works perfectly for me.

I wanted to use it for Thunderbolt, but it doesn't work there. Max length 50 cm
The cable would be available

Should work without any problems. You may want to check which USB-C version your docking station uses. The extension cable is v.3.1 and has the following features: Max. transfer speed: 10 Gbit/s. Max. transfer speed: 10 Gbit/s, Max. power supply: 5 A. Max. power supply: 5 A. If the docking station uses the same or older version, this is not a problem. If it is newer, the power supply or data transmission may suffer when using the extension cable.
