I am the only coffee drinker in my family and usually only two cups a day, both early morning before DW wakes up. Also during quiet times in parks.
Read here about one guy who converted a Kuerig and removed the heating element, just boiled water poured into reservoir and ran pump. Neat if you have power to run pump.
My daughter somehow came up with a couple of Kuerig Mini's that didn't work well. In looking at he inner workings of the Mini, I discovered that the motor for the hot water pump is 12VDC, so I took one and stripped everything out except for the pump that pumped the hot water from the heat chamber to the pod holder, rerouted the intake tube from the heater to the reservoir. Now I heat water on the stove and pour it into the reservoir and push the on/off button and my cup fills with hot coffee without 120 VAC.
So depending on how many are having coffee, I can perc a pot or run the Kuerig.
