“So you plug in whichever connector is correct for the country you are in, then plug that into the wall socket (can also fit to extension cables too), then plug it into the Raspberry Pi (3B, in my situation) and electricity at the right level flows through all the cables into the Raspberry Pi and makes it work.
It’s great.”
“I was having an issue with my Pi Zero W where it would start to lag roughly every minute or so. I was using just a regular phone charging cable and had stuff plugged into the USB port. When I took the USB stuff out, it stopped lagging, so I figured the cable wasn't delivering the power I needed.
This power supply solved that issue entirely and now I can plug whatever I want into my Pi, and overclock it without any issues at all. Note that on mine, the raspberry is just an engraving and isn't black as shown in the photos.”
