I intend to construct a DIY base camp shower and dish sprayer. I have been searching for an appropriate submersible water pump to plug into a small inverter to a 12-volt cigarette lighter power pack (car jump starter). I need to attach adapters for a hose with a shower head and think that approximately 1+ gallons of draw per minute is practical. I would possibly use a five to six-gallon reservoir, heating water on a car-camping propane stove. My biggest concern is amp draw.
Maxi-Jet NJ-400 Submersible Utility Pump, $21, is a powerful aquarium pump with an adjustable flow up to 1.8 gpm. Whale Standard Submersible Electric Galley Pump, 3.5 gpm, 3 amp, $48, is a bit overkill. Although I am primarily a backpacker, I did not like the looks or performance of any of the solar shower bags, Sea-to-Summit Pocket Shower, $30, or even the NEMO Helio Pressure Shower (foot powered), $100. The Coleman Hot Water On Demand, $260, seems to be catastrophic failure prone from reviews that I have researched.
Does the Maxi-Jet NJ-400 Submersible Utility Pump sound feasible?
