Fridge slide.
Depends on the fridge, and how hot it is out. a good one 20 minutes twice a day a poor one 30 minutes 4 times a day.
A fridge or freezer normally runs on only 600watts so the smallest generator you can get will run both at the same time, well pumps take bigger...
I get power outs a few times a year and I run the generator 3 times a day for 45 min to an hour and a half to keep the phones up, do a load of laundry ect. I use the central heating to warm the house up and keep it warm with the wood stove. Well tops off the pressure tank in the first ten minutes, then the coffee, after that things just idle along.
Wasteful on gas but comfortable. I like low stress comfort.
Worth a couple extra bucks a day. And Unless you like pulling on a starter rope, get a OHV Honda. Starts first pull every time. Or buy electric start.
Starting a generator in a dark snowstorm is worth not fighting.
What we have is a pull type Honda, IIRC. Don’t know anything else about it. I just want to walk into the utility room and flip a switch and have what we need.
In a long term situation, it would make sense to me to only run it to fill up a 50 gallon container of water and off and on for micro wave and refrigerator - stuff like that.
Short term, if gas is plentiful and not too expensive, we would just flip a switch and leave it running till power was restored.
