I did something like that but with viture pro glasses included. they're available refurbished for $300. works really well with samsung dex. if you don't have a samsung galaxy then I wouldn't.

I actually mowed the lawn with the glasses on the other day. couldn't miss fishtank

if you want to use it while charging you need a really good dock that has displayport over type c and charging in. I have the selore seuc0424

I'd still rather use a 14 inch laptop for serious work
