“I have not made any electrical rests, but it works with my Pi 4, and my Pi 3 (Not both at the same time)
It is smaller than the Pi 3 supply, and being white, easy to identify, to switch off the Pi. (I need a power strip with a switch for each socket.)”
“I purchased the Pi 4 to use for my Home Automation project. This little beast packs lots of power and so far has been coping well with whatever I have thrown at it. The heat is not much of an issue if you couple the Pi4 with a passive cooling case.”
