One side of this comparison rests on a reported figure. Water Makers Australia Performance Double 140L · 12V feed is published by the manufacturer and corroborated across independent lookups, but we have not yet read the figures page-in-hand the way we have for the rest of the table.

This is not measured total running draw; the motor rating may describe shaft output rather than electrical input. How we source figures.
