Update for everyone: the 140w charger I mentioned above works great. It was charging at around 90w for the hub, goes to about 110w if I add the remote. Still got about 30w headroom for other devices.
I am guessing the previous 90w charger does...
The charging rate and time is very slow using the USB side for all my hubs compared to using the usb-c to usb-c option on my Anker and well worth the price I paid for it, which I don't think was all that much compared to all the other things I've...
I haven't used that one, but it should work.
If you're looking for something a little more compact, I'm using the 100W Anker Nano Charger to charge my Air 3S batteries.
