My concern is can you make it truly bright and truly portable. You can cheaply get bright non-portable (flat panel) and portable non-bright (Capsule Max) but I’ve never seen a bright portable.
I bought a Capsule Max it is the brightest which I’d say is portable, requires a darkened room but is a good standalone solution for temporary larger screen video with sound. I have oodles of MP4 so don’t need Wifi.
Will this new one be powered from a Powercore 20W 20000Ah? External power is useful to extend standalone for power outages.
I am expecting an outage at home soon, we’ve been getting brown-outs last week which is a sign of failing something in the grid.
