12-volt power for macerator pump
Our newly purchased macerator pump requires 20-amp, 12-volt power. Have you found a simple way to supply that power to the pump? I'd like something that would plug into our 120-volt house power.

A simple way to provide 20 amps at 12 volts.. Easy peasy. Plug into house power (With an RV) also easy
Inline fuse (25 amp) to battery positive. Another to battery negative (RV's battery) 10Ga red/black (red to positive) speaker wire from there to a DRY compartment near the sewer outlet (I added a compatment) anderson power polls on the end (NOTE there is a standard way to arrange them Looking into the poles you want the red one on the right with the tab on top)
Provided wires from there to pump (Fuse is in the handle)
Plug in the RV and let the converter re-charge the batteries or power the unit.
Using it on some other kind of device. More or less the same hookup only a small (IE 35 amp) Converter like a progressive Dynamics 9200 series and a good size rechargable battry
Side effect Use battery with small TRUE SINE WAVE inverter to watch TV or run a fan during power fail.
