I saw a defrosting plate online and it didn’t look like it had to be plugged in or heated, but claims to defrost frozen food fast. How does something like this work?

So after a few minutes of researching these things, I’m going to guess what you’re looking at is made of aluminum. Aluminum is a great thermal conductor, mean it can easily transfer heat. In this case, heat from the air into the frozen food.
These things work best when something has a large surface area. The frozen food absorbs heat in the tray. Since the tray is slightly elevated on legs and has ridges or slats in the top, it’s surface contacts plenty of air flowing past it, absorbing heat from the air in the process which in turn is absorbed by the cold meat. This whole process is called conduction. It’s nothing magical, and definitely isn’t as fast as advertised, but if you have an aluminum pan or sheet, it’ll work almost as well and save you some defrosting time.
