Question: This comes with the 170w adapter?
Document: I have been using this docking station for a couple months now and it has worked perfectly. It connects/disconnects easily and the multitude of ports have worked as expected. It comes with the massive 170w power supply which is great for desk use. I have been using it with a twin screen monitor setup which allows you to still use the built in laptop monitor for a third screen.
Make sure you need the 170W adapter before purchasing this version of the dock. It's a great dock and it's awesome that USB 3 is finally included, but most people don't need the 170W adapter.
The plug on the power cord was not intended for USA use. Amazon could not supply me the proper power cord so I purchased an adapter in order to plug into an outlet. Seems to me that if you sell a product in the US market, it should comply with US specs.
if you want to turn your think pad to a powerful desktop but still want mobility this is the product for you. its a solid product which comes with an extra 170W charger which is a plus. I really loved it
The mini dock is the very best way to enjoy the portability of a notebook that has to work in more than one room. The ease of just dropping the notebook on the mini dock and having all your accessories already connected is priceless. This one supports two external monitors and it does work. Only three stars because Lenovo doesn't believe in putting HDMI ports on its mini docks. I had to buy adapter cords from Amazon to get things connected.
The pros -  all the data, audio and video ports we could want. My goal was to use my W520 to replace the aging home wireless network desktop PC that runs two printers. The ThinkPad MiniDock Plus Series 3 (170w) docking station ought to be able to do the trick. The W520 fits into the docking station with no problem. The power brick is the same size as my W520 power brick, so no issues there.However, I am unable to power-on from the docking station.
needed 2 dvi video outs and this works fine. price is outrageous but it is what it is, and if you need dual video from your thinkpad, this is the only proper way to go. the cables (all have chips to adapt to dvi/hdmi) don't always work, but the 'proper' chip in this dock does work. that's why they charge so much.
You can lock the laptop to the dock but what's the point if you can't secure the dock to something?
Works as discrided. I attached dual monitors and had some challenges adjusting the video settings to display properly every time I dock and undock. Not sure if this is a laptop or docking station issue. Docking is a bit of a challenge, laptop does not dock easily.
Work well so far. Driving two monitors. Glad I got the 170 watt power supply. 90 watts way to small! Thanks
