How long will a power station run a refrigerator?
A 1,000 Wh power station runs a typical fridge for about 14 hours. It averages about 60 W, draws 150 W while running and needs about 900 W for a moment when it starts.
A fridge compressor cycles on and off, so a 150 W fridge averages about 60 W over a day.
How long by battery size?
| Battery | Runs a fridge for |
|---|---|
| 300 Wh | about 4.2 hours |
| 600 Wh | about 8.5 hours |
| 1,000 Wh | about 14 hours |
| 2,000 Wh | about 28 hours |
| 3,600 Wh | about 2.1 days |
Hours = battery Wh × 0.85 (inverter losses) ÷ 60 W average draw.

Would a generator be better?
The smallest generator in our comparison that can start a fridge on its own is the Honda EU2200i (1,800 W running, 2,200 W starting). A generator suits long outages and heavy loads; a power station is silent and safe indoors. Size a generator for this.

How long will a 500 Wh power station run a fridge?
About 7.1 hours, at an average draw of 60 W.
How long will a 2,000 Wh power station run a fridge?
About 28 hours.
What size power station do I need to run a fridge for 24 hours?
About 1,864 Wh with our 10% margin; the smallest model in our comparison that fits and can start it is the EcoFlow DELTA 2 Max (2,048 Wh).
How many watts does a fridge use?
About 150 W while running, about 60 W on average over time, and about 900 W for a moment when it starts.
What is the smallest power station that can start a fridge?
In our comparison, the EcoFlow River 3 Plus: 600 W output and 1,200 W surge.
Can solar keep a fridge running?
Partly: our planning figure of 700 Wh of solar on a good day covers about 9.9 hours of a fridge.
Would a generator be better for a fridge?
Not for this alone: a power station covers it for a day, quietly and safely indoors. For multi-day outages or heavier loads, the smallest generator in our comparison that starts it is the Honda EU2200i (1,800 W running). Never run a generator indoors.
