Aside from the myraid of good arguments about why this is a good thing to be happening.
Having, in a past attempt to quit smoking, used a few. The ones that they tried to make look like a cigarette.
Yeah they are really awful, utterly horrid. I'd rather suck turd out a camels arse. Turned out I'd also rather just stop entirely (sorry, I only lasted about 18 months. but I will mange it)
not smoke/vape related.. but I remember buying a couple of these one shot power banks. Disposable thing, it was in like a pouch rather than a case. I did some googling... it looked a lot like this:

link disclaimer, DO NOT buy this crap
but it was about 10 years ago, they were like a quid each and I think I saw a basket of them at a market stall or something and I got 2. Anyway, lived in my work rucksack for a very long time, never being needed. I lost one, and the otherone the pouch got a bit damaged, so I thought sod it, lets open it.
Couldn't believe it, I was expecting a bunch of alkaline button batteries connected together through a little zener circuit, but no, it was a straight up lithium ion battery.
