Does this ASUS Dual 4K USB-C dock come with a power cable?
Not totally clear if it can supply up to 100W or if it is the docking station power supply that is 100W. Thanks
As markus.scheib said, you do need a separate power supply. In fact, the docking station only acts as a gateway to power the device to which it is connected with the usb-c cable. The 100W is the maximum power supported by the docking station to power another device.
