I’m not sure why you’re referring to the Pi4

My first post in this thread was talking about Pi low power and small physical size. I was talking about all Raspberry Pis in general. I never put forth the Pi5. You did when you raised the 5V5A requirement. That exists only on the Pi5. You'll also see in that first post of mine is where I disavowed any recommendation of Pi5.

You then went on in your next post about Raspberry Pis needing active cooling and heat sinks. Again, that is only the Pi5, which again, I said I don't support.

So if you're wondering why I keep talking about Pi4 and below is because those are the ones I like. In this thread you keep posting facts about Pi5 (without pointing out that those only apply to Pi5), and so that's why I keep referring to Pi4 (and below).

You say you don’t use or recommend the Pi5 and yet you’re seemingly arguing that its power supply requirements aren’t a big deal and that improvements should absolutely not be made to it.

I'm arguing power supply requirements shouldn't be made to Pi4 (or below). I don't use Pi5.

As far as heat goes, these devices already need heatsinks and case fans, so the difference seems negligible.

Pi 4 and below don't require active cooling. I want to keep it that way.

Also, good luck using a Pi5

Again, I offer no defense of Pi5. I don't use it and don't recommend it.

Most laptops today use power supplies that meet or exceed those specs.

Non those are USB-PD power supplies that increase voltage up to 20V in order to deliver more power. No USB standard that I'm aware of offers 5A at 5V.

Also, good luck using a Pi5 any further than 3ft from a wall outlet unless you want to rig up your own power supply using some 14/2 Romex with a USB C connector soldered to the end.

Low power draw but ridiculous power supply requirements of 5V5A (depending on the model) with a USB-C connector which isnt a thing outside of this specific application meaning
they’re going to be expensive and hard to source.

That's only for the Pi 5 (the highest end unit), and I'll agree that at that level its hard to justify a Pi over a larger computer. Even for the Pi 5 its not that hard to find those Power Supplies. Most laptops today use power supplies that meet or exceed those specs. You're right that those are more expensive than Pi 4 and below Power Supplies.

They should have just done a barrel plug or put an effing voltage regulator on board like Arduinos.

Again, no defense of Pi 5 from me. However, for everything below Pi 5, HARD PASS on a voltage regulator. I don't want that heat in the tiny Pi case. At the lower power requirements of Pi4 and below USB power is fine.
