Hard to say. The spec sheet calls out 4 Amps for the 12 Volt system or 32 Watts for a single gallon.

If it includes the time it takes to produce that gallon, there would be enough information to do the energy calculation.

I guess it would be 48W/h as it makes about 1.5 gallons an hour.

Which to scale back up and complete the comparison to the state of the art in lab "batch reverse osmosis" systems I was originally talking about that's ~12.7 kWh/m3.
