Watts voltage x current so in raw terms the pi zero w at idle will use 0 6w however that ignores any power loss in the psu converting from mains electricity to the 5v needed by the pi zero w. The b models have an 8p8c ethernet port and the pi 3 pi 4 and pi zero w have on board wi fi 802 11n and bluetooth.
