XPS 15 9570 only draws 65 Watts from 130 Watt Dell-made USB-C adapter
I just bought a Dell USB-C power adapter rated at 130 W to use with my XPS 15 9570, the thing works but when I check the BIOS, it shows up as 65 W power source. I'm surprised the 9570 can (allegedly) draw 130 W from docks like the Dell TB16 but not from a 130 W adapter manufactured by Dell.
My BIOS is up to date, I have checked for any available updates before posting.
Has anyone here tried a 130 W brick or dock with their 9570? Did the 9570 draw more than 65 W from it?
That brick wasn't cheap, if I knew it wouldn't deliver the full 130 Watts, I would have just bought any standard 65 W for less than half the price. I'm a bit disappointed.
Thanks @ejn63 I did see that post before making mine, but all I could learn from it is that standard 100 W is not supported, while 130 W is supported with specific Dell docks. Most importantly that discussion does not link to any reliable sources, and no users on that thread had a 130 W adapter to play with.
For example, there's this very relevant statement made by a user: "I also remember reading somewhere that the 130W USB-C charger won't work as a 130W source with "normal" XPS 15s, even though those systems can accept 130W over USB-C from Dell docks.".
