I never made any comment about whether or not the powerbank itself would charge.
All my comments were directed at using it to power the computer.
I cannot guarantee that using an underpowered supply would not damage your computer.

Please state clearly:
- The output voltage & current stated on the xps 15 9550 power supply adapter's label
- The output voltage & current stated on the PW7015L powerbank's label (this might be 2.3A at 19.5V)

I am not sure the exact information you are asking for because I do not know much about volts and current stated. I might even give you the wrong information because I am not sure what exactly I am looking for. I could take a picture of it and post it here but the issue is these numbers are so tiny on the back of these charger/powerbank that you can barely read it from a photo.
I just posted exactly what I saw on the back of my dell xps 15 9550 power adapter and the old PW7015L powerbank with it.
I also posted exactly what I saw on the back of the dell xps 15 9520 power adapter and the PW7018LC usb-c powerbank with it.
I just noticed a mistake now because these numbers on the back of the adapter and powerbank are very tiny. It is barely readable unless you look way up close with a flashlight.

On Dell site, it shows the PW7018LC as compatible with the dell xps 9500 which was released 2 years ago and it uses usb-c as well. Now when i look at the power adapter specifications here.. this looks almost the same as the xps 15 9520. However the issue here is for the xps 9520, the Output current (continuous) of only 4.5A and Rated output voltage of 20 VDC means minimum 90W?
But with the dell xps 15 9500, since it has Output current (continuous) of either 4.5A, 3A, 3A, 3A and Rated output voltage of 20VDC, 15VDC, 9VDC and 5VDC, then that works? Because it would be something like 3 x 20 = 60 so minimum 60W with the xps 9500?
Is that correct?

Okay so want to update the thread.
With that dell powerbank i bought, when i connect it to my xps, seems like in about 50 minutes... the powerbank drains to zero. Now is that normal or not? Now if you are using the laptop while the powerbank is plugged in, seems a few more minutes less than that.
Reason is because this xps uses lot more watts than my old xps even if the nvidia graphic driver is not in use?
Now it seems that adapter is available on dell site again. Anyone here use it with their old barrel powerbank and if so, how much time you get with it before it goes to zero? With my old xps and the old powerbank, it would take an hour and a half or so before it goes to zero. But if i use that old barrel powerbank with that adapter with my newer xps... i got to assume it won't last that long and probably no more longer time than the new usb c powerbank i bought from dell? Anyone here done a test or use the old powerbank with adapter for a new xps?
Also... anyone bought that anker powerbank people talking about? Anyone used it with a newer xps and how long it last before the 5 bars go to zero? Seems like as huge as that powerbank is in terms of watts... it isn't that more than either of the dell usb c or the dell barrel powerbank? Also anyone here can confirm there is exact same amount of watts in either dell usb c or the old barrel powerbank?
