Putting on my speculating hat...
These are emerging in part because of the rise in popularity of USB power banks. As USB power banks increase in capabilities, the cost to produce them goes down. Especially for tech that is a little behind what is cutting edge. It may even be somewhat like medication going from name-brand to generic. Eventually it becomes cheap to produce something similar and almost as good as the original.
If you'll notice, not only do these charge similar to how you'd charge a USB power bank, but some of the better versions of these double as power banks. People don't like being cold. And for $10 or even $20, a reusable warmer sounds like a good deal. They also in a great "impulse buy" and "stocking stuffer" price range.

I have a heated vest and a heated jacket. I don't feel a need to warm my car up while wearing either of them. Not as good as heated seats, but mine are cloth and don't transfer cold like leather. I just got three on the last deal.
