Dell Venue 11 7130 Charging Issues

I am a purchaser of a second hand dv11 and was quite happy. I did not realize however that the fast charging was not working. I've used cables designed for fast charging along with the cable that came with the dell adapter, it is always at 3w.

I thought hey let me purchase a dock to remedy this issue. It came today, everything works minus charging the device!



Any recommendation at what I should be looking at? I'm running windows 10 btw.
