LEDI Scout SW20
Reported figure, not yet confirmed by us. The output and draw above are published by the manufacturer and corroborated across independent lookups, but we have not yet read them page-in-hand the way we have for the rest of the table. It is shown so the system can be compared at all, and excluded from our best-and-worst-in-table claims until confirmed. The manufacturer states a draw of 180–220 W; the midpoint is used, matching how we treat published output ranges. How we source figures.
What you are actually buying
Drawn to this model’s own published specification: portable, 1 × 2521 membranes, and a pump driven by a 12V DC motor.
What it costs to run
A four-person crew using 25 litres a head needs 100 litres a day. On this system that is:
DC systems have to fit inside the energy your solar, wind and alternator can spare. Run the numbers against your own bank in the calculator.
Is it worth it?
At 10.0 watt-hours per litre it sits mid-table: 2.7 times the energy of the most efficient system we rank, and about 2.0 times less than the thirstiest. 1,000 Wh puts 100 litres in the tank.
Suits
- A couple or a small crew. 20 litres an hour is a trickle by design; run it for 5.0 hours and the day is covered without a spike in the load.
- 12 volt boats with no inverter. It runs straight off the bank, drawing about 83 Ah a day at 100 litres.
- Boats where it has to come off. A portable unit stows, moves between boats and can be serviced on a bench rather than upside down in a locker.
Look elsewhere if
- Larger crews in a hurry. 20 litres an hour means 14.0 hours to cover a charter crew's day.
Worth pricing against it: Schenker Zen 30 makes 30 litres an hour at 3.7 Wh/L, so the same 100 litres costs 633 Wh less every day. See the Zen 30 →

Common questions
- How much power does the LEDI Scout SW20 use?
- It draws 200 W and makes 20 L/hr, which works out to 10.0 watt-hours per litre. Making 100 litres — four people at 25 litres a head — costs about 1,000 Wh, or roughly 83 amp-hours from a 12 V bank.
- How long does the Scout SW20 take to make a day's water?
- At its rated 20 L/hr, 100 litres takes about 5.0 hours. Output falls in cold or silty water, so treat that as a best case rather than a promise for every anchorage.
- Who sells the LEDI Scout SW20 in Australia?
- 1 verified Australian business is listed as LEDI dealers or specialists, including LEDI Watermakers. Each entry links to the manufacturer or company page that proves it.
- Is the Scout SW20 efficient?
- It ranks 18 of 34 rated systems in our table on watt-hours per litre, where lower is better. The best in the table is 3.7 Wh/L. It uses a conventional high-pressure pump, which is the main reason it sits above the energy-recovery systems.
- Is the LEDI Scout SW20 worth it?
- At 10.0 watt-hours per litre it sits mid-table: 2.7 times the energy of the most efficient system we rank, and about 2.0 times less than the thirstiest. 1,000 Wh puts 100 litres in the tank. It suits several cases: A couple or a small crew. 20 litres an hour is a trickle by design; run it for 5.0 hours and the day is covered without a spike in the load. Look elsewhere if: Larger crews in a hurry. 20 litres an hour means 14.0 hours to cover a charter crew's day. We publish no opinion on build quality or reliability, because we have not tested it.
