One side of this comparison rests on a reported figure. Dessalator D100 DUO 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. The comparison is shown because it is still the best available, not because it is settled. Dual-power unit. This row is the DC mode at its stated 700 W maximum; the AC motor is rated separately and is not tabled. How we source figures.
