G2 Dockingstation combo-cable power connection type fit to HP OMEN 15-dh0002ng

I want to use a dockingstation for my HP OMEN 15-dh0002ng.
The HP Dockingstation G5 with USB-C works fine but doesn't provide a power supply.
For this reason I'm thinking about the G2 230W Dockingstation with the splitable combo cable.

Does anybody know how the power jack is called for the HP Omen and the G2 Dockingstation (Type of Plug / Diameter etc.). I can't find the specification of the plug itself. I think the power supply for the OMEN has as 4.5x2.8mm coaxial power connector, but I'm not 100% sure.

Looking in the specifications of the dockingstation the OMENs are not supported but this doesn't mean anything, cause HP doesn't always know about their own products 😉 and the G5 works fine.

Ok,
I have the HP Dockingstation G5 with USB-C and the G2 thunderbolt.
The Poweradapter fits to the OMEN Laptop and is the 4.5x2.8mm coaxial power connector,.
So far so good, but there is one thing.
The G5 dock supports two screens using my OMEN 15-dh0002ng, while with the G2 I can only connect to one.
I don't knwo why this is the case cause looking to the specifications the OMEN supports Thunderbolt and it also tells me that it is connected via Thunderbolt to the dock. So I don't see any reason why this shoundn't work, but it doesn't.

Ok, solved it! 😀

There was something wrong with one displayport cable. Exchanging this solved the issue and now both monitors are connected.

So I can confirm:

• The HP Dockingstation G5 USB-C and the HP Thunderbolt Dockingstation G2 230W are compatible with HP OMEN15-dh0002ng.
• Further the HP Power connector for the current HP OMEN Series (2019) and the zBooks is an 4.5 x 2.8 mm coaxial jack.
