Differences ThinkPad Thunderbolt Dock Gen 2, Workstation Dock (170W) and Workstation Dock (230W)

Hello everyone,

 

I recently bought a ThinkPad X1 Extreme and I am now locking for a suitable Thunderbolt 3 dock. Although I've read a lot of posts about various docks I am still a little confused about which one to choose. It seems like the following ones would all work with the X1 Extreme:

 

1. Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 135W:

https://www.lenovo.com/ca/en/accessories-and-monitors/docking/universal-cable-docks-thunderbolt/Thun...

2. ThinkPad Thunderbolt 3 Workstation Dock (170W):

https://www.lenovo.com/ca/en/accessories-and-monitors/docking/universal-cable-docks-thunderbolt/Thun...

3. ThinkPad Thunderbolt 3 Workstation Dock (230W):

https://www.lenovo.com/ca/en/accessories-and-monitors/top-tech/Thunderbolt-WS-230W-dock-US/p/40AN023...

 

Please correct me if I am wrong but to me it seems as if the only difference between these docks is that the workstation ones come with two AC adapters each and a special Thunderbolt/Power cable to avoid using two different cables. Or are there any other technical differences?

 

So if I am okay with a two cable solution couldn't I just use the Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 135W and connect it via Thunderbolt while at the same time use my 135W AC adapter to charge the laptop?

 

I would greatly appreciate it if someone could please clarify this for me.

 

Thanks a lot in advance.

Hi Luki5980!

 

Welcome to the community forums.

 

We don't recommend you to use two adapters at the docking station at the same time since the Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 135W is not designed to use two AC adapters on this docking station. This might cause damage to the docking station and other devices connected to it. Based on the links below the reason why the ThinkPad Thunderbolt 3 Workstation Dock (170W) and ThinkPad Thunderbolt 3 Workstation Dock (230W) requires two AC adapters, because they have more ports to extend multiple external monitors that requires more power. Check the links below.

We recommend to use the docking station how it is designed.

 

Regards,

Hi,

 

Thanks for getting back to me.

 

Sorry, there was a missunderstanding. I didn't intend to connect two AC adapters to the docking station but only one to the laptop and one to the dock. That shouldn't cause any problems, right?

 

BTW I ordered the 170W Workstation Dock.

 

Thanks and best regards.

Thanks for clarifying. It would work as long as the charging port is different with the port where you need to connect the Thinkpad Thunderbolt Dock Gen 2 on your laptop.

Nonsense - all of three docks are exactly the same. The difference is that “Workstation” variants come with two power adapters (170W + 65W / 230W + 65W) instead of one (135W) and a thunderbolt+power cable to carry extra power (as thunderbolt cable’s maximum is 100W).

Again, the docks themselves are same.

Can someone confirm this? 

Sound it be possible connecting the 230W PS to the 65W connection and thus providing enough power for the TB3 cable?

Has anyone tried to connect 65W adapter in addition to 135W adapter to the Thinkpad Thunderbolt Dock Gen 2 and get at least 4K@60HZ + 2K@60HZ?

And we're back...
