The video was pretty poorly structured to be honest, should have been longer with better information and they didn't post their data anywhere to read. I mean they had ~30 seconds just growing plants...

But the point stands, they weren't testing 1 to 1 on batteries (hard to do anyway). There's good reasons for why manufacturers havent just cranked it all to 200W charging.

The video isn't a sudden revelation, we already knew how batteries behave, they've been tested in labs under much more strenuous conditions too.
