Drawn to this model’s own published specification: portable, 1 × 40in membranes, and a pump driven by a petrol engine.

A four-person crew using 25 litres a head needs 100 litres a day. On this system that is:
1.5 hrun time per day
fuelenergy per day
$85per L/hr of capacity
No electrical draw at all. Budget roughly 1.0 litres of petrol for that day.
Is it worth it?
Rainman Portable Petrol 75L publishes no rated draw at a stated voltage, so it cannot be ranked on energy. It is judged here on output, configuration and price, and the energy question stays open until the figure exists.
Suits
- 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.
- Boats with no electrical headroom at all. It makes its own power, which is the point, and asks nothing of the bank.
Look elsewhere if
- Anyone who does not want a second fuel aboard, or who wants to make water while away from the boat.

Common questions
- How much power does the Rainman Portable Petrol 75L use?
- Nothing from the battery bank. It runs a petrol engine instead, burning roughly 700 ml of fuel per hour, so about 1.0 litres for a 100-litre day.
- How long does the Portable Petrol 75L take to make a day's water?
- At its rated 55–82 L/hr, 100 litres takes about 1.5 hours. Output falls in cold or silty water, so treat that as a best case rather than a promise for every anchorage.
