Wireless Display Adapter with Battery included

[Haldi]

Hei,

I've been wondering.
Has anyone ever heard of an Wireless Display Adapter with an included battery?
I know it would be possible to simply use a 5v Powerbank designed for Smartphones and connect it via USB cable, but that doesn't look quite right.

i couldn't find anyone. Does such a thing exist? Have you ever seen or heard of one?

Finding a Wireless Display Adapter was enough challenge for me, let alone one that has it's own battery.

For years I have been trying to find technology that works and looks good, not much luck yet, but that's why I own a surface pro.
