A three outlet space saver works by alloeing you more more room to plug in your items. It is a device that plugs into an outlet converting it from single.
It's pretty handy you just put it into a plug and then you can plug into more devices in it. It's not a fire hazard. I've been using them for so many years now and I don't think it is a hazard at all or at any cost so it's great.
