Plastic free protable electric stoves/egg cooker? (from a reliable brand)

Hi, wondering if anyone can recommend a protable electric stove and/or egg cooker that is ideally stainless steel from a reliable brand.

We own a gas stove but would love to use it as little as possible, but we also don't want to be heating up plastic (many of the options we're finding have lots of plastic components).

Just wondering if anyone has an reccos.

The reason we want a reliable brand is it's hard to know if it's truly stainless steel otherwise.

Thanks!
