So low standby 1) actually makes it so the connected usb-c cable is not powered on at all. That means that USB-C cable with display will not turn on and that when removed from the mains it will not show any electricty. 2) it will only use around 0.5 ...
33 Wh maximum and only works when turned off. In turned on mode it only does 14 wh as said. Assuming it uses power bank it can do 17W. But usually it can't.
