Precision 5550 Docking Quesiton

Hi:

I recently purchased a MDell Precision 5550 laptop and have a USB docking station from a previously owned Precision 5520.  The docking station does not have a USB C input, so I am unable to connect the 5550 to the docking station.  The 5550 was shipped with a 130W power source.  I have a 180W power source I have been using with the 5520 which will connect to the USB docking station.  Can I use the 180W power source in the USB docking station and connect the docking station to the 5550 using the USB C output from the docking station?

Thanks in advance for any help.
