I have a home laptop and a work laptop.  I sometimes work from home.  I want to have two monitors and I want ease of switching between the two laptops, so I am looking into a docking station.

My laptops are as follows:

Home:  Dell Latitude 15 5000 Series (E5570)

Work:  Lenovo Thinkpad 20KS003PUS (E580)

I would love a docking station that has power delivery for both but it looks like that is not possible.  The Dell has the barrel end to the power supply and the Thinkpad has a USB-C end to the power supply.

I am looking at the "ZettaGuard USB 3.0 and USB-C Universal Docking Station with Dual Video Monitor for Windows,MacOS, 12 in 1 USB C Hub with Dual 4K HDMI,Gigabit Ethernet,Stereo Audio in/Out.6 USB 3.0 Ports." which is sold on Amazon. 

I have one monitor so far with an HDMI connection.  So, I can buy the other monitor once I choose the docking station.  I will be connecting a wireless keyboard and mouse (two USB ports needed) and a thumb drive. 

I work in IT so I am not a novice but I also don't work on the hardware side.  So, I don't know a whole lot.  My guess is that using this docking station I will still use my power supply for each laptop and will connect using the USB 3.0 connection to both laptops (the USB-C connection on the Thinkpad will be used by the power supply since this docking station does not provide power delivery).

Do I understand this correctly?  Is there anything I am missing or incorrect on above?  Is there one that is not too pricey that you would recommend instead and why?

Thank you for your help.  I hate returning items so I want to make sure this will work for me before I buy.
