“I bought it to power a RPi4 with an external SSD - it works perfectly and was reasonably priced. I haven't had any power draw warnings in Raspberry Pi OS with the external drive running, so it appears that the amperage of this power supply is ample for that purpose.”
“I have a few Raspberry Pi 4B's running various projects. These official Raspberry Pi Foundation power supplies are great and have never let me down. I like to attach via a switched USB-C cable for convenience and saves wear-and-tear on the port. Great service as always from Pimoroni. Superb service given the problems with Covid.”
