I went digging for videos on Twitter (as that's where the article says they're floating around).

Well yup. There are some blinkenlights on that stage.

I share the cynicism I infer in your comment; I don't think that this demo really gives any weight to the idea that this will be an actual, practical, product. However, the commenter asked for a video and there it is.

I think it's great that you found the links and posted the video. Certainly relevant.

My cynicism is wholly directed at the company which I believe to be a fraud. I'm sorry if I accidentally sent some of it in your direction.

In the video she holds the phone 20cm from the charger, and directly facing it.

This is a scenario that's well known can work (at high power levels which are not generally legal).

What doesn't work so well is charging off axis and at higher power levels.

This is a school science project level demo...
