Shaded rows are our picks. Assumed load: A modern full-size fridge that pulls 150W when the compressor runs and runs about 40% of the time (roughly 1.4 kWh a day), with a 1,200W startup surge.
The startup surge decides what works
A fridge compressor is a motor, and a motor needs a hard shove to get moving. For a moment it pulls far more than its running power. Our numbers assume a 1,200W startup surge.
Every power station has two output ratings. One is what it can give all day. The other is the surge rating, the most it can give for a moment. If the fridge asks for more than the surge rating, the station shuts its outlet off to protect itself and the fridge never starts.
That is why the three 300W units in the table are marked “can’t start it”. Their surge rating is 600W. Battery size has nothing to do with it. The EcoFlow River 3 Plus is rated for exactly 1,200W of surge, so the table shows a runtime, but there is no margin at all. An older or larger fridge could trip it.
What a fridge draws once it is running
Much less than people expect. A modern full-size fridge pulls about 150W while the compressor runs, and the compressor runs about 40% of the time. That averages 60W, or roughly 1.4 kilowatt-hours a day. A kilowatt-hour is 1,000 watt-hours, the same unit as on a power bill.
After the losses in turning battery power into household AC, a day of fridge takes about 1,700Wh of battery. So 1,000Wh units land near 14.5 hours and 2,000Wh units near 29.
Older fridges, a hot kitchen and a fridge packed with warm food all push the number up. If your fridge has a yellow EnergyGuide label, divide its yearly kilowatt-hours by 365 and compare with our 1.4.
Keep the door shut and use the gaps
Food-safety guidance says a fridge keeps food safe for about 4 hours with no power if the door stays shut. That changes how you use a battery. A gap is not an emergency. You can unplug the fridge for a while to run something else, or to let the station recharge, and plug it back in.
Every door opening lets cold air out and makes the compressor run longer, so decide what you want before you open it. A cheap fridge thermometer tells you where you stand. The same guidance uses 40°F as the line for the fridge section. Before a storm, fill empty shelf space with bottles of water. Cold mass helps the fridge hold its temperature.
For long outages, look at solar input
Once an outage passes a day, the question is how fast you can refill. Solar input is the most panel power a station can accept. To replace a day of fridge use, a station with a 400W input needs more than four hours of strong sun at full panel output. One with a 1,000W input and enough panels needs under two. Panels rarely reach their rated output, so plan with spare. Of our picks, the Anker Solix F3800 accepts up to 2,400W, the Bluetti Elite 100 V2 1,000W, the Anker Solix C2000 Gen 2 800W and the Bluetti AC70 500W.
Plug it in the simple way
Run a heavy-duty extension cord from the power station to the fridge’s own plug. Never plug a power station into a wall outlet to feed the house. If you want it wired into your home’s circuits, that is a job for an electrician.
The picks in detail
Bluetti Elite 100 V2
- 14.5 hr
- Full-size refrigerator
- $489
- $0.48 per Wh
- 25 lb
- Weight
14.5 hours of fridge time for $489, the lowest price in the 1,000Wh class. That covers an overnight outage and part of the next day. Its 3,600W surge rating is three times the 1,200W the fridge needs to start, so there is real headroom. It also has a 1,000W solar input. If the outage runs into a second day, it can take in a lot of sun fast.
What fits
- 3,600W surge, three times the startup need
- 1,000W solar input
What does not
- One charge does not last a full day
- 25 lb to move to the kitchen

Anker Solix C2000 Gen 2
- 29.0 hr
- Full-size refrigerator
- $899.99
- $0.44 per Wh
- 41.7 lb
- Weight
29.0 hours per charge means a full day and night with a few hours left over. Its 4,000W surge rating is more than three times the startup need. The reasons to choose it over other 2,000Wh units are an 800W solar input and one expansion battery that brings it to 4,096Wh if outages in your area run long. At $899.99 it costs $0.44 per watt-hour, about $21 more than the cheapest unit this size.
What fits
- 29.0 hours per charge
- Expandable to 4,096Wh with one extra battery
What does not
- 41.7 lb, so plan where it will sit
- About $411 more than the Bluetti Elite 100 V2
Anker's list price is $1,499.99. Anker lists a 9W idle draw, which is low for this size.
Anker Solix F3800
- 2.3 days
- Full-size refrigerator
- $1,979.99
- $0.52 per Wh
- 132.3 lb
- Weight
The fridge runs for 2.3 days on a charge. Its 2,400W solar input is second only to the EcoFlow Delta Pro 3's 2,600W, which gives plenty of room to refill from panels between nights. At $1,979.99 it costs $0.52 per watt-hour, against $0.68 for the Delta Pro 3 with similar runtime. Be clear about the size. It weighs 132.3 lb, and its wall charge time is not listed.
What fits
- 2.3 days per charge
- 2,400W solar input
What does not
- 132.3 lb
- Wall charge time is not listed
Anker's list price is $2,199.99. A newer F3800 Plus is sold alongside it for more.
Bluetti AC70
- 10.9 hr
- Full-size refrigerator
- $359
- $0.47 per Wh
- 22.5 lb
- Weight
For $359 you get 10.9 hours, enough for an overnight outage if the door stays shut. The catch is startup. Its surge rating for motors is 1,500W against a 1,200W need, a cushion of only 300W. Bluetti also advertises 2,000W of Power Lifting, but that mode suits simple heating devices, not compressors. A modern fridge should start. An older or larger one may not, so spend $130 more if you are unsure.
What fits
- $359, the lowest price that clears the startup surge
- 10.9 hours covers one night
What does not
- Only 300W of surge margin
- 10.9 hours is less than half a day

Verdict
For the common overnight outage, buy the Bluetti Elite 100 V2. The Bluetti AC70 saves $130 but leaves only a thin surge margin, so it suits newer fridges. To cover a full day and night on one charge, buy the Anker Solix C2000 Gen 2. For outages that run several days, the Anker Solix F3800 with solar panels is the only pick here that gets past two days. Do not buy any 300W unit for a fridge. It will not start the compressor, however big the battery.
How these numbers were worked out. Runtime = battery capacity × efficiency ÷ average watts. We use 85% efficiency for AC outlets and 90% for DC and USB ports, because some energy is lost as heat on the way out. A model is marked "can't run it" when the device needs more watts than the outlet gives, or a bigger startup surge than the unit is rated for. Your own device may draw more or less than our assumed load, so treat these as estimates. Prices were checked on 2026-10-04 and change often. Full method
