What Size Power Station Runs a Refrigerator During an Outage?
To run a modern refrigerator through an outage you need a power station with at least ~1,000Wh of capacity and a continuous output of 600W or more to absorb the compressor start-up surge. A full-size fridge draws roughly 100–200W while running but spikes to 600–1,200W for a second when the compressor kicks on, so output headroom matters more than raw capacity. A 1,000Wh unit like the EcoFlow Delta 2 keeps a typical fridge cold for about 12–18 hours; step up to a 2,000Wh+ unit like the Bluetti AC200L or Anker SOLIX F3800 to cover a multi-day blackout. Below we match real refrigerators to power stations that can run them and estimate the runtime for each.
The cross-vertical comparison
Refrigerator running watts vs. power-station capacity and estimated outage runtime. Runtime ≈ usable capacity ÷ average fridge draw (~150W), accounting for the compressor duty cycle.
| Power Station | Capacity | Continuous Output | Surge | Est. Fridge Runtime |
|---|---|---|---|---|
| EcoFlow Delta 2 | 1,024 Wh | 1,800 W | 2,700 W | ~12–18 hrs |
| Jackery Explorer 1000 Plus | 1,264 Wh | 2,000 W | 4,000 W | ~15–22 hrs |
| Anker SOLIX C1000 | 1,056 Wh | 1,800 W | 2,400 W | ~13–18 hrs |
| Bluetti AC200L | 2,048 Wh | 2,400 W | 3,600 W | ~24–36 hrs |
| Jackery Explorer 2000 Plus | 2,042 Wh | 3,000 W | 6,000 W | ~24–36 hrs |
| Anker SOLIX F3800 | 3,840 Wh | 6,000 W | 9,000 W | ~2–3 days |
Our picks across verticals
EcoFlow Delta 2
A 1,024Wh battery with 1,800W continuous output (2,700W surge) easily absorbs a fridge compressor spike and runs a typical refrigerator ~12–18 hours — the cheapest unit we trust for fridge backup.
Bluetti AC200L
2,048Wh and 2,400W output run a refrigerator for roughly a full day on one charge, and the unit is expandable past 8kWh if you add batteries for a longer blackout.
Anker SOLIX F3800
3,840Wh and a massive 6,000W output cover a refrigerator, a chest freezer, and a window AC at once — a true short-term home backup, not just a fridge sitter.
LG LRFLC2716S
A French-door LG that sips power; pair it with a 1kWh station and you stretch backup runtime well past a thirstier model. Energy-efficient fridges are the easiest to keep cold off-grid.
Frigidaire FRSS2623AS
A mainstream side-by-side with modest running watts; a mid-size power station keeps it cold overnight without breaking the bank on either purchase.

Frequently Asked Questions
What size power station do I need to run a refrigerator?+
At minimum a ~1,000Wh power station with 600W or more continuous output. A full-size refrigerator runs at roughly 100–200W but the compressor surges to 600–1,200W on start-up, so the output rating (and surge rating) is what determines whether the station can run the fridge at all. A 1,024Wh unit like the EcoFlow Delta 2 keeps a typical fridge cold for about 12–18 hours.
How long will a power station run my fridge during a blackout?+
Estimate runtime as usable capacity divided by average draw. A refrigerator averages about 150W once you account for the compressor cycling on and off, so a 1,000Wh station runs it roughly 12–18 hours, a 2,000Wh station about a day, and a 3,800Wh unit like the Anker SOLIX F3800 two to three days. Adding a solar panel during daylight can extend a fridge almost indefinitely.
Why does the surge rating matter more than capacity for a fridge?+
A refrigerator compressor draws a brief in-rush current several times its running wattage when it starts — often 600–1,200W for a second. If the power station's surge rating is too low it will shut off the moment the compressor kicks on, no matter how big the battery is. Pick a unit with a surge rating comfortably above ~1,200W; every station in our table clears that bar.
Can I recharge the power station with solar during the outage?+
Yes — every unit here accepts solar input, and adding a panel during daylight can offset most of a refrigerator's daytime draw, effectively extending runtime indefinitely in a sunny multi-day outage. This is the difference between a power station and a gas generator: silent, fumeless, and rechargeable from the sun.
Should I get a bigger power station to run more than the fridge?+
If you also want to power a freezer, some lights, phones, and a CPAP or a window AC, step up to a 2,000Wh+ unit with 2,400W or more output (the Bluetti AC200L) or a 3,800Wh / 6,000W unit (the Anker SOLIX F3800). Both run a refrigerator with plenty of headroom for the rest of an emergency load.
