User Manual Elite Gourmet ESB-301F Countertop Electric Hot Burner

I already had answer this and told you I make a mistake in buying it because the cord was way too small and when you plug it in its close to the wall

Yes, you can cook a steak on it.

I haven't measured the temp range, but it cooks as well as any other portable electric stove.

No don't make no noise at all

It should. It heats up pretty quickly and, unlike some others, doesn't cycle off and on when a certain high temperature is reached. I have been very happy using it mostly with a pressure cooker.

I use this to keep a metal coffee carafe warm. Works fine. When needed, I will also use it to keep other things warm. I did not get it for the purpose of heating or cooking.

Not unless that dish indicates that you can cook on it.

I would think that the hot plate could be used in the science classroom, remembering that some of the glass beakers had a direct flame under them.
