USB-C charger for Elitebook 840 G5

[Nadia_D]

I forgot to take a charger for my Elitebook 840 G5 with me on business trip and stuck only with quick charger USB-C for my phone. It rated 67W, but voltage is strange (please see it on the picture).

Can I use it to try to charge my laptop?

The voltage output for a USB Type-C power adapter, whether it is for a phone or a laptop is the same.

I would be quite surprised if a phone USB type-C power adapter would be rated at 67w.

I will take a look at the image and return to this thread. For some reason it was not approved.

OK. That is a strangely written specification. It won't have enough power to fully charge your laptop, but it will work as a trickle charger. Using it won't hurt anything if not used as a long term solution.

This is the USB Type-C charger that your laptop, per the Maintenance & Service guide, is compatible with.

It is a charger for quick charge the Oppo A78. Output 5-11V, 6.1A (that is why its 67W. But as I now Elitebook accepts 20V, so 11V will not be enough?

It isn't a laptop power adapter.  There is no way of getting around that fact. 

Your Oppo A78 mobile phone's battery has nowhere near the charging requirements of the laptop.

I suggest that you source a travel power adapter.

"It isn't a laptop power adapter. "

It is just a marketing label - you either have the right amount of voltage and watts or not.

I finally tried my adapter and it able to charge my laptop in power off state. Unfortunately insufficient power to charge "on line", but it's better than nothing)
