This is a used docking station and works great.  Got a different computer that doesn’t use this type of dock.  DOES NOT come with the power adapter.  It works with my Latitude D820.  If you are unsure if it will work with your Dell computer, I suggest you contact Dell to ask the model of docking station that will work for you and compare it with this one.  No returns.
