The heating element is only about 100W, and in some cases is a lightbulb.
You get it boiling and then sling it in the slow cooker. The tiny heat keeps it just simmering.

I don't actually know anything about them.

That's not true
You get it proper boiling, but it takes time, and you shouldn't open the lid often. Usually it has two settings, the strong one at the beginning if you're in a rush, and once it starts boiling, you can put it down.

I use it all the time, it does boil. And I'm not dead.
