Question about Dell WD22TB4 180W Thunderbolt 4 Docking-Station

There is no 'charging cable' but a power supply unit for this docking station.
The scope of delivery of this docking station includes the matching power supply unit.

I assume that this is a device that is to be charged via the docking station. Any charging cable with USB-C or USB-A can be used. The docking station supports both. The device that is to be charged is decisive. If the device to be charged only supports USB-A, any cable with USB-A can be used. For devices with USB-C, any USB-C cable can be used. In other words, the device to be charged is decisive.
