So the negative review, the product says
Where it says Zbook.
The words further down in details says
“Please ensure that the DC connector (4.5 mm × 3 mm) is the right size for your device.”
Reviewer laptop is a Zbook
The diameter of the charger pin is correct. The difference is the length, it’s been designed too short by Anker.
They’d not see any reason to think it wouldn’t work. I’d say this is the fault of Anker not listing specific Zbooks don’t work.
Now as to why it doesn’t work, without knowing exact model I can’t check, but if I go to HP site I see many chargers , same barrel, but they differ by Wattage.

I see 45W to 200W, so in the absence of details my hypothesis is this laptop needed more than the 60W, which if they’d come here and asked to read off the specs off their supplied charger, we could have found the minimum Watts for the model and formed a prediction. For sure if a charger is more than 60W it’s a warning might not work.
But, because Anker has a no quibble return policy on Amazon it’s easy to return for refund.
I predict many negative reviews until Anker does a better description, e.g. take this failure and grow a list of Zbook it shown don’t work.
