I wonder when they're finally going to one-up each other with the 18650 model number itself? Make it 18660, 19650 or 18650000!

Anecdote: back in 2004, a friend brought home a cheap digital audio player from her vacation to China. IIRC, it said on the front panel that it could play back MP3, MP4, and MP5.

That's a real thing, there: https://docs.fileformat.com/video/mp5/

It’s still bogus and not a real file format. Just MP4 files renamed into MP5.
