“Works great and got rid of the annoying low voltage warning and icon that was constantly on the screen. I had been using a 4 amp supply with nothing but the Pi 5 attached so I knew the issue was something else. In reading the Pi 5 notes from RaspberryPi.org, I found the supply must have the PD (?) spec cable as the Pi 5 circuitry is looking for that to insure there was sufficient power.
My only mistake was in my hurry to order it, I accidentally ordered the UK plug instead of the US plug. 'My bad'. Fortunately I was able to buy a UK to US power adaptor and did not have to wait again for the shipping delay to get the correct plug on a new power supply.”
