I use a Birdcord for powering 9v pedals from a USB powerbank and it works flawlessly, noise free even when daisy chaining an entire pedalboard (I use the 12v version to power my digitakt when on the go):

That really opens up a ton of options for you I think.
Norns Shield does look cool, current prices also holding me back a bit but I have to agree that it is likely that it will only get worse.
