What Size Power Station Runs a Refrigerator During an Outage?
Match the actual refrigerator startup surge and running load to the station output, then size capacity for the hours you need. Runtime is battery watt-hours × conversion efficiency ÷ measured average watts; the average already includes compressor cycling. At an illustrative 150W average and 85% efficiency, 1,024Wh gives about 5.8 hours and 2,048Wh about 11.6 hours. These are planning estimates, not measured runtimes or guarantees that food stays cold. Test your fridge and monitor its temperature.
The cross-vertical comparison
Illustrative fridge-only AC runtime = capacity × 0.85 ÷ 150W average draw. The 85% conversion factor is an assumption; 150W already includes compressor cycling. Actual loads, inverter overhead, temperature and battery condition change runtime. These are not bench tests.
| Power Station | Capacity | Continuous Output | Surge | Est. Fridge Runtime |
|---|---|---|---|---|
| EcoFlow Delta 2 | 1,024 Wh | 1,800 W | 2,700 W | ~5.8 hrs |
| Jackery Explorer 1000 Plus | 1,264 Wh | 2,000 W | 4,000 W | ~7.2 hrs |
| Anker SOLIX C1000 | 1,056 Wh | 1,800 W | 2,400 W | ~6.0 hrs |
| Bluetti AC200L | 2,048 Wh | 2,400 W | 3,600 W | ~11.6 hrs |
| Jackery Explorer 2000 Plus | 2,042 Wh | 3,000 W | 6,000 W | ~11.6 hrs |
| Anker SOLIX F3800 | 3,840 Wh | 6,000 W | 9,000 W | ~21.8 hrs |
Our picks across verticals
EcoFlow Delta 2
1,024Wh and 1,800W continuous output, with a published 2,700W surge. At the table’s 150W average and 85% efficiency, estimated runtime is 5.8 hours. Test startup compatibility and set AC timeout to never as directed in the manual for intermittent fridge loads.
Bluetti AC200L
2,048Wh and 2,400W output. The same assumptions give 11.6 hours for the fridge alone; additional loads reduce that time. Compatible expansion batteries can add capacity.
Anker SOLIX F3800
3,840Wh and 6,000W output. Estimated fridge-only runtime is 21.8 hours at 150W average and 85% efficiency. Check voltage, startup surge and combined watts before adding a freezer, pump or air conditioner.
LG LRFLC2716S
Compare the exact model’s energy label and measure consumption over a full compressor cycle. Capacity or brand alone does not establish its backup runtime.
Frigidaire FRSS2623AS
Use measured watt-hours over a representative day, including defrost cycles and door openings, to size backup for this refrigerator.

Frequently Asked Questions
What size power station do I need to run a refrigerator?+
Check the exact fridge startup surge and running watts against the station output and surge duration. Capacity determines hours, not whether startup succeeds. At 150W measured average and 85% efficiency, 1,024Wh estimates 5.8 hours. Test the actual pairing before an outage.
How long will a power station run my fridge during a blackout?+
Estimate hours as capacity in Wh × conversion efficiency ÷ average watts. For the illustrative 150W average and 85% efficiency, 1,000Wh gives 5.7 hours, 2,000Wh 11.3 hours and 3,840Wh 21.8 hours. Do not apply compressor cycling a second time to an average that already includes it.
Why does the surge rating matter for a fridge?+
Compressor startup can exceed running watts. Check the actual surge, its duration and the station limits; a large battery does not compensate for insufficient output. Also check low-load AC timeout settings: EcoFlow instructs Delta 2 owners to set AC timeout to never for intermittent refrigerator loads.
Can I recharge the power station with solar during the outage?+
Compatible panels can extend runtime, but weather, placement, charging limits and actual daily harvest matter. Compare measured solar watt-hours with daily load energy and losses; a panel rating cannot guarantee indefinite operation.
Should I get a bigger power station to run more than the fridge?+
Add the measured average watts of every load to estimate runtime, and separately check combined running watts, startup surge and voltage. For home CPAP, follow the device and station manuals and the care-team backup plan; settings and adapters change consumption. Do not rely on a general portable station for emergency life-sustaining equipment.
Does battery runtime tell me whether food is safe?+
No. Use an appliance thermometer and keep the fridge at or below 40°F. USDA says an unopened refrigerator keeps food cold about four hours without power; discard perishables above 40°F for more than two hours. A fixed compressor on/off schedule cannot establish safe food temperatures.
