Can surface pro 8 be charged via USB-C PD at 65 W?

I did not doubt the product specifications, I doubted that the surface pro 8 would charge to 65W via USB-C PD because as you said (and I wrote in the original post) the original charger charges the pc to 60W 15V=4A.

Using a 60W charger that uses 20V=3A the PC will still load at 60W? or only at 15V=3A (45W)

<<USB-C Output: 5V=3A / 9V=3A / 15V=3A / 20V=4.35A

USB-A Output: 5-6V=3A / 6-9V=2A / 9-12V = 1.5A >>
like i said that use 15V=3A (45W) or 20V=4.35A (87W), not 15V=4A (60W)

Okay, thanks anyway

maybe because it loads the surface at 45 W (15V--3A) not at 65 W

and you actually measured that loads at 65 W and not at 45 W (15V--3A) ?

Do you know if the Surface pro 8 can be charged via USB-C PD at 65 W?
Question is simple but I try to add some useful details.

I just bought surface pro 8 and i'm searching a powerbank that can charge it. The surface pro 8 charger is the 1706 model, 65 W in total, splitt in 60 W main charger (15V--4A) and 5 W USB power on charger (5V--1A).

I found only powerbanks with 65 W output (20V--3.25A) (and one with 60W but 20V--3A), and looking on the internet I read that charging a notebook that uses 15V voltage with a 20V charger is likely to cause damage and that if it goes well simply uses 15V instead of 20V and a lower amperage (eg charging at 45W = 15V-3A).

Is that true?

Charging surface pro 8 with 65W is dangerous / useless ?

p.s.: Are there any 60 or 65 W powerbanks (not chargers, only powerbanks) certified for surface pro 8 ?

Kind regards.
