There is a slight limitation on what kind of cookware you can use on them. The pots and pans have to be ferromagnetic. Aluminium cookware doesn’t work and it looks like stainless can be hit or miss depending on how it’s made. It’s not a big issue unless most of your cookware doesn’t work on it.

The article says they are 120v induction stoves so they don’t have to do updates to the electrical. The battery also allows them to work if the power goes out. For how long? Idk.
