3A... I'm making my own PoE Hat for Rpi 4B.
And I'm confused cause the official PoE HAT only provides 2.5A, but it says it could compatible for Rpi4...

I believe that under most circumstances the RPi (even RPi4) will not draw that much current. For example, each USB port is specified to be able to supply a certain amount of power for peripherals, so if you're not using them (or using them to the fullest) then the actual amount of current required from the supply will be less.
