at half the amps used, 18 amps for the Power-survivor compared to 9 amps for the Spectra is a huge difference. Spectras membranes and filters can be found practically anywhere in the world, have a world wide distributorship and dealer network. The PS membrane is proprietary, Spectra's are not. Spectra's Clark pump has a lifetime warranty PS does not. Again the PS is a good machine but it really doesn't make much sense.
Thank you for the comments. As stated, I do not wish, whatever the qualities of a proprietary solution, to go down that road or to have to carry or obtain expensive, single-sourced spares. Our focus is on a robust, no frills system with a moderate output, although I am becoming persuaded that a 20 gallon/hour AC-powered system may be more efficient than a lower-flow DC-powered system in that I could get a week's worth of drinking water
during a two-hour motor
(I have a pilot house and can use rainwater from a separate tank for washing
I agree that a nine-amp system has the edge, as this falls within the desirable range of both the Hondas and the inverter
I already possess, meaning I don't have to rig an engine-driven setup with a dedicated or partially dedicated alternator
Thanks to the CF Brains Trust for some illuminating information and great advice.
