This is my latest sci fi gadget and I'm probably the last one to them. It's what we used to call a four-gang except it's an eight-gang and has added USB charging slots. If you've not seen one of these beasties in the flesh the black squares are plug sockets; two to a side, and there are switches on top to isolate the sockets. The button above the USB slots is also an isolator. This is a good deal neater than my usual arrangement of having four-gangs strewn across the room. It is also a surge-protector so my surges should be safe.
