“It's a power supply. It works. It delivers enough current to run the Pi4b, and externally attached SSD and a Logitech keyboard dongle. Peace of mind in an official power supply.”
“Works fine. When overclocking (6V 1800MZ) with 64bit Ubuntu 20.04 I get undervoltage warnings and wondered if a 4A unit would be better. However, I find that Raspian is fine for my requirements and this is faster and less power hungry. this means I have abandoned Ubuntu Desktop after usng it for over 10 years.”
