My company is replacing my Latitude E7440 with a Latitude 5490 equipped with an i7-8650U CPU. Unfortunately, the docking station that we currently use is no longer compatible and my company won't pay for a new one.

Yet, I don't see myself plugging and unplugging cables 10-20 times per day so I'm considering buying one myself. I have tried to find the "right" model, but I'm confused with all the existing references (D3100, D6000, WD15, TB15, TB18, WD19....).

Right now, I connect to my docking station:

• a 22" FHD monitor via Display Port
• a 22" FHD monitor via DVI
• a USB mouse
• a USB keyboard
• a RJ45 cable
• power

Ideally I would like to have just one cable to plug/unplug. I could do with an additional cable for power if that would really drive the costs down.

I'm also OK with used or refurbished if the product is reliable.

What would you recommend for my needs? How mouch power would I need for the docking station? Is 130W enough or should I go for 180W?

Many thanks for your help!
