Okay, I’m actually onboard with those things. It’s usually a cable with a single wall plug on one end and four C13 plugs at the other. So you could plug in two monitors, a desktop PC and a printer, say, with just one socket. They’re a lot neater than having a whole power strip and four cables. I’ve also seen ones that split one C14 into four C13s but I’m not as sure how I feel about those.
