Actually the PI 5 uses USB-C with PD implemented, so it really
needs a proper USB-C supply with full PD support.

I am not sure how many of those supplies that you mention
are USB-C compliant.

I have an original RP and also an RP3 and I don't have
problems with them. As I recall without checking the
RP5 has extended that tolerance to at least 5V5 and maybe more.
I think that it uses the USB-C PD at 9V in some (all?)
circumstances, so presumably it can tolerate at least that
potential on the USB-C connector.

I did wonder, but wasn't sure if an RP4 image might have a custom
kernel with drivers for some rp5 peripherals missing. I suppose
it seems unlikely that the modules would be trimmed like that.

Thanks for the reply.
