How long will a power station run a refrigerator?

Updated · How we calculate

A 2,000 Wh power station runs a typical fridge for about 22 to 38 hours. A 3,840 Wh unit, about 41 to 71 hours.

Most modern fridges use 1.1 to 1.9 kWh a day. Where yours lands depends on its size and age. The yellow EnergyGuide label lists its yearly kWh; divide by 365.

Common questions

How long is food safe if the power stays off?

About 4 hours in a closed fridge, and about 48 hours in a full, closed freezer (24 if half full), according to the USDA. Keep the doors shut and check with a thermometer; 40°F or below in the fridge and 0°F in the freezer are the lines that matter.

Will it handle the compressor starting up?

All three units above list surge ratings of 4,800 W or more. That is well beyond the brief draw of a household fridge compressor kicking on, so the surge rating isn't the limit here.
