No association just looks like an interesting add on.  https://www.portabl.com/

I think the product is a scam. They fundraised on kickstarter like 8 years ago and never shipped, but there are other products on the market that fill the same niche.

If you want an extra monitor and want to travel with it look at asus zenscreen, otherwise normal monitors rule.
