Unfortunately, attempts to charge a laptop with a mobile device charger rated at max 22.5W will most likely be futile.
The two USB-C chargers HP has recommended for this device are:
65 W, wall mount, 3 pin, USB-C 860209-850
45 W, wall mount, 3 pin, USB-C 860210-850
You need a much more powerful charger to properly power the device.
FYI, you might be able to charge the laptop slowly if you plug in the Huawei Mate 9 charger when the laptop is shut down.
Hope this helps,

HP sells a 60W output USB-C power bank - the Spectre USB-C Power Pack. Officially this is an accessory for the Spectre models that charge over USB-C, but I cannot see any reason why it will not work with other HP notebooks that charge over USB-C.

Confirmed laptop will charge when powered off with a Huawei Mate 20 Pro supplied charger.
Input: 100-240v ~50/60Hz @ 1.2A
Output: 5V @ 2A or 9V @ 2A or 10V @ 4A max (40w)
When the device is powered on, it will not charge and the battery will drain. I can't yet tell if it's discharging slower than normal with the abovementioned USB-C charger plugged in or not, though I suspect it's not charging at all whilst in use as it drops inline with what I would expect from normal usage.

I think it is worth a try, maybe there is something in the settings of the BIOS

Hello Eddy ,

Used my Elitebook 840 G5 USB type-C charger to charge my Huawei P20 mate Pro phone .
Might this event prove to be harmefull to my phone battery ? Will it do any harm to charme my phone with my laptop charger.
