Not sure about your specific canners. Refer to your manual.
However, I can tell you that a regular water bath canner is only good for acidic stuff. I can tomatoes, and add a bit of lemon juice, just because some tomatoes are not as acidic as needed.
Anything else needs to be canned under pressure. The amount of pressure and time needed varies depending on product and size. I think there are some canners that can be plugged in and heat is raised to the appropriate temperature and pressure.
You might be able to purchase a counter top burner or hot plate that would work on a regular pressure canner.
My canner came from Walmart for 100 bucks, but I just have a regular electric range - not a smooth top.
