For folks who want to just run medium mode or want to see if the stand alone unit (no PSU) comes sooner, I think I found a pretty cool product for only $34. It's rated 28V/5A and comes with 2 USB-C ports (my thinking was running two nanos from this)!
***----> Actually now that I'm thinking about it, 140W rating though not going to be enough. I think conservatively if you are running medium mode, you should plan for at least 90-100W allocation per unit. Maybe someone can chime in and confirm this. If I can find one of these with a higher rating, I'll update.

They dropped the ball a bit on psu.
I like the unit but they should have done two speeds.
60 and 90 watts. And they could have done a better psu.
