The RPi 4 8G has a maximum 3A required, it does not necessarily need all 3A to run as it will depend on the application, I believe mine runs at approx 1.2A @ 5V. 3Amps is a buffer for some really intensive clocking and tasks.
While I was testing before i got my RPi 4 I used my Raspberry Zero W. It worked well in the remote application but failed on PHD2. For some reason PHD2 wouldn't start and was not from the power supply either.
RPi Zero also couldn't work well with Ekos and Kstars running.
