Hi, you can absolutely charge it with a USB-C adapter, there shouldn't be any difference at all since it supports 130w charging over USB-C as well. Use a Dell 130W USB-C adapter and you will be fine, third party adapters sometimes aren't fully supported/recognised.
Hello I qas wondeing if there are any difference in performance using USB C to charge my Dell XPS 15 9570  compared to the power cord. I think there is some problem with my charging port so I was thinking of buying USB C to charger my laptop.
