extension is an extension. Ok some have other purposes like a surge etc. It's just an outlet with an extension cord. With 15 feet cable. That's what I was looking for. I needed a longer cord than most extension cords provide. So it was perfect for my needs. I live in a very old house with wiring updated in the 70's. Of course, I can't overload any of my outlets with modern electronics. I updated a couple of outlets, one of which I connected to this one.
