I think the fuse is blown

Hey guys, today I did something stupid. I connected the switch to a power bank using a usb-c to usb-c cable. Problem was, i connected it to the power bank port that was intended to charge up the power bank.. the switch immediately turned off with an audible click sound and it won’t turn back on. No amount of long pressing the power button or trying to get it into recovery mode will work... I have no warranty left on it. Do any of you know which fuse it would be? Do I need to replace the usb-c port or is there more to it? Any idea how much an official repair at Nintendo would cost? Any help is greatly appreciated! Thanks!
