This photo shows that you need at least 9 volts to wake up the battery controller after it being set to shipping mode, it has absolutely no indication of any power usage requirements for the device to operate. Even if the power usage of the device falls into this range, it is a coincidence and had nothing to do with this image.
I highly doubt it’s going to need a supply that can do at least 9V to exit shipping mode, at least I haven’t yet seen a device behave like that. I more so think that’s what power supplies Valve suggests to use if you want to play and charge simultaneously, that being said I believe actual power usage is going to be somewhere around those 27W at max so the battery doesn’t discharge, with 45W being a buffer to charge the battery while in use, though that’s still just a wild guess.
