Wireless charging at high distances

Hi /sci/,
I think this is the right place to ask, but I was wondering if this demonstration is bullshit or not?

This Japanese company, Aeterlink, Inc., has claimed that it has built a wireless charger that can work up to a distance of 20m, is this even possible?
Website: https://aeterlink.jp/
Description:
Aeterlink is leading the next generation of wireless charging with Air Plug, an RF-based
scalable technology that enables wireless charging of small electronic devices up to 20
meters away while also allowing wireless data communication among those devices,
ensuring an interoperable ecosystem.

What's the largest possible electromagnetic field distance? I've seen a lot of wireless charges coming out lately but they only work at a very short distance of an inch or less, but not at large distances. Is it even possible to build something like this?
