REFRIGERATOR + FREEZER BACKUP
A fuel generator can cover longer outages with a safe outdoor location and fuel plan. A battery works indoors, but its runtime depends on your appliances’ actual energy use.

Compact gasoline option
1,800W rated · 2,200W maximum · 120V
For a modest refrigeration load when portability matters. Start appliances separately and check the combined running demand.
Know the limit: Gasoline only. Less headroom for two compressor starts or additional appliances.

3,900W rated on gas · 3,500W on propane · 120V
For a refrigerator, freezer and other measured essentials when a smaller generator leaves too little margin.
Know the limit: Larger and heavier. Output drops on propane. A single unit does not supply 240V.
Check Westinghouse iGen5000DFc on Amazon ↗Indoor battery bridge
2,048Wh capacity · 2,400W AC output · 120V
For homes without a safe generator location, or a shorter indoor bridge while you arrange recharging.
Know the limit: Stored energy runs out. Confirm motor startup compatibility; boost-mode wattage is not a compressor guarantee.

Use fuel generators outdoors at least 20 feet from doors, windows and vents, with exhaust directed away. Never operate one in a garage or backfeed a home outlet. Use appropriate dry, grounded outdoor cords; household circuits need correctly installed transfer equipment.
Keep appliance thermometers inside and doors closed. An unopened refrigerator keeps food cold for about four hours; a full freezer about 48 hours, or 24 hours when half full. Use food temperature and the official safety chart to decide what to keep.
