On: The Raspberry Pi 5 Is No Match for a Tini-Mini-Mic...

I can’t find any evidence that RPi5 supports PPS or that anyone makes a 5V/5A PPS charger, except perhaps a massive 100W charger or something along those lines. It’s a silly voltage/current combination.

edit: PPS is not supported. See:

Oh, so it needs a 5A power supply. The problem is that usually requires a >60W supply, which will be willing to provide 5A. It also requires a marked cable. I think it can legally be done with PPS if power supply supports 5A.

It is weird that Pi5 doesn't do USB-PD 27W supply which is common. It would require converter from 9V. But that would cost money.

The problem is that the Pi requires specific combination of (5V && 5A), which is rare. IIUC even many 65W adapters don't support it.

I wonder if it has to do with the fact that Pi is shipped as a bare board without case. Power circuits are sometimes required to have enclosures.

Thanks for the correction!
