How long will a portable power station run a refrigerator?

Q: How long will a portable power station run a refrigerator?

About 9 hours on a 1 kWh station and about 18 hours on a 2 kWh one, for an average fridge. The average US home's fridges use 839 kWh a year (EIA), about 96 W averaged over the day, and a station delivers roughly 85% of its rated capacity after inverter losses. Ready.gov says a closed fridge keeps food cold for about four hours, so you can run it in shifts and stretch any battery.

Home wiring is a job for a licensed electrician. New circuits, outlets, transfer switches and battery connections must meet the National Electrical Code and your local rules, and many need a permit and inspection.
