Called "Dock" because it's designed to plug into the left side of the USB-C and place under the laptop to tilt it at a slight angle, but for laptops, which only have USB-C on the right side, it's bigger and looks like a key. The size of the product can be an issue if you want to carry it around. If you want to take it with you, bizhub might be the best option. However, the dongle should have enough ports for each use, unless you want to output to multiple 4k monitors simultaneously.
