Their power needs must be absurdly strict, considering they didn’t want the 12v -> 220v -> 12v loss for an M1 chip.
The idle cost of inverters can be quite high.
EcoFlow power stations draw somewhere around 30w with the inverter switched on with no load.
The idle power of a Mac Mini at the wall is a few watts total.
