Charging Zbook Power G8 with USB-C charger

[msssm]

Hi, the technical specs say, that charging via USB-C is possible with

5V@2A/12V@3A/15V@3A  ...45W

...65W

...90W

I have tried a Xiaomi 1A1C 12V charger with 100W over USB-C. I also tried a UGREEN 65W charger supporting PD3.0. Both chargers don't work and the HP helper splash says, that the power is not enough for charging. What is required?

I don't like buying a special charger for each device which was the idea behind all the QC and PD standards on USB-C.

Hi,

I believe it is not possible to charge over the USB-C port 

Those notebooks need loads of power and come with a 120W or 150W ac adapter.

Maybe you are referring to the fact that the machine supports BC 1.2 and can charge different external devices with different power ratings.

I don't think so.

http://h10032.www1.hp.com/ctg/Manual/c07638746.pdf  In the user manual, page 76, the section is called "Input power". There are mentioned modes from 45W USB-C up to 90W USB-C.

Moreover, why should the error message be "Not enough power for charging" (free translation from german) if charging is not supported at all?

Have Zbook power g8 (came with 150w power supply) and usb-c charging works for me.

In my case its plugged into a dell u3818dw and its usb-c port is rated at 100W PD for reference.

Edit: Looked up those chargers the OP posted, the Xiaomi 1A1C is a 30W charger..  12Vx2.25A (really 27W) - the lowest power on the PDF is 45W. 

The other one appears to really be 60W for port C1 and C2, not sure why its not working. Perhaps the charger or it could even be the cable, I know linus tech tips did a video about how all usb-c cables are not the same and he can only get some to work with high power and only some to work with thunderbolt etc.

The manual you refer to on page 76 also says "The computer can operate on DC power within one or more of the following specifications. . The voltage and current for your computer is located on the regulatory label." Check to see what it is and then check your xiomi charger specs.

edit- there seems to be a lot of confusion lately on USB-C charging. I notice people often list the wattage as their primary concern. The USB-C spec has varying voltages also, off the top of my head it's from 5V to 25V. These are sensed by the charger where it adjusts if it can to the correct voltage.

Even if we don't need to discuss Xiaomi specs here, where did you find that spec about the Xiaomi 1A1C and only27W? All I find is 5V3A/9V/2A via USB-A and 20V5A via USB-C.

Whatever I'm looking for a 100W USB-C charger working on 12V automotive voltage and working with the Zbook. As my Xiaomi phones already support 65W charging, I purchased their 100W charger thinking it could also charge the Zbook.

Does anybody have a working car charger for the Zbook Power?

What other 12V automotive charger beside USB-C is matching the Zbook Power?

I have a universal charger "Ansmann DCPS 2460" and ordered all available adaptors for older Elitebook Series I own, but they don't have an adaptor for the Zbook plug (4,5mm inner and 3mm outer).

In the QuickSpecs for the ZBook Power 15.6 inch G8 I checked all the Accessories but can't find any mobile charger.

Now see there is more than one Xiaomi 1A1C charger and see the 100w car charger your talking about - I was looking at a house charger they make that happened to have max output of 12V x 2.25A so assumed that's was the 12V you mentioned.

I've been looking for a car 100W PD charger myself, and struggled to find one so I had to read more about that charger.

The USB-C specs are odd - it only lists 20V-5A and not the full range like normal PD specs would - also lists the max total output as 68W for some reason. - ignoring those things I went looking for more answers.

Found a few reviews, but the only one that actually tested with laptop or any actual load was this youtuber: /watch?v=RhLI0eQn5C4  - He translates the Chinese fineprint in the manual and it says the 100W USB-C output only works on Xiaomi 100W fast charging phones.  Then he tests it on his laptop and is only able to get 40W out of it (he verified 60W on another 65W charger he had), then he tested it with a PD dummy plug and was only able to get ~55W before its protection would kick in and shut it off.

As far as options, doesn't appear to be too many - Some that look like a typical laptop charger with brick in the middle amazn "HKY 100W USB-C Car Charger" - or another PWR brand one that comes up for more.
