We are on grid but could be self sufficient for several months off. We always have stacked pantry , fridges and freezers and have our own Well and ample wood pile. Our 5500w diesel generator can run : pumps, fridges, freezers, lights Tv and wifi…all at the same time . If we we run …20 minutes x three times per day= one to two litres fuel/ hr…that’s all that is needed to maintain the household.
The heavy draw power items such as hot water and cooking can be done on a propane camp stove and we have wood heat. When the generator power is off, which is most of the time, the house is still comfortable.

I have a propane generator which powers essentials, in an area which loses power frequently, sometimes for days. I also have battery-powered lanterns. I feel very prepared. My area can get cold in the winter. A few days ago it was 6 degrees in the morning, and we experienced rolling blackouts. The generator was the best investment I ever made.

Not sure if it would be considered a generator, but I have a portable power source that I charge up every 30 days. It's really only good for powering small devices for a short time, but better than nothing. There is a big generator in the basement of my condo complex in case of emergency.

I also have 6 battery powered camping lanterns and a few flash lights plus 12 battery powered candles, and oodles of batteries.

I do have a butane camp stove, plus my condo complex has propane barbecues, I can use as my frozen food thaws.

Since I live in a warm climate, the biggest thing I stock up is ice for emergencies. I freeze large water bottles to keep my food cold in case the power goes out, or if I have to evacuate taking my food/water with me.
