Any USB-C PD experts in the house?
For some reason my Anker power brick won't negotiate 15V with my Steam Deck, only 9V. But if I pass through an Anker battery with dual USB-C, it'll give 15V to the deck and take 45W in... using 20V.
Does this adapter just not support 15V and the Deck doesn't support 20V? That seems silly. I have an Apple 61W that seems to act this way too.
Why can't we have nice things?
