“Having received this device, I plugged one end into the wall socket, the other end into my Raspberry Pi 3, then, being uncertain of what would happen next, took cover behind a heavy filing cabinet while I flicked the power switch on. It is, after all, a Pi Zero power supply according to it description. Well, there was no need to be so cautious. The power supply came on quietly and has since proved to be a reliable and trustworthy partner in keeping my Pi 3 powered on and active. I ask for nothing more, I receive nothing more. It just gets the basic things right.”
