Which power station will run your refrigerator?
For a typical fridge, get the EcoFlow DELTA 3 Ultra (3072Wh): it runs a full day on one charge, the lowest price that does. From a big brand, get the EcoFlow DELTA Pro.
Buy the EcoFlow DELTA 3 Ultra (3072Wh) ($1,299 at Amazon). Lowest price from EcoFlow, Jackery, Anker or BLUETTI that runs a fridge a full day: the EcoFlow DELTA Pro ($1,799).
A typical fridge needs about 2,000 watt-hours a day. Buy a station that holds that much you can actually use, and check it can start the compressor.

Who this is for
You want one thing from a battery: the food still edible when the power comes back. Lamps can be candles and phones can wait for the car. That makes this the cleanest plan to size, because a fridge is a single motor with a predictable habit, and the least forgiving one to get wrong, since guessing low costs you a freezer emptied into a bin.
How much battery you need
A fridge is not a load that sits still. The compressor runs until the box is cold, shuts off, and waits for it to drift back up, so your energy comes from the fraction of the day that motor turns, not the watts on the label. The diagram above is that cycle. A newish fridge in a cool room with the door mostly shut spends roughly a fifth of the day running; the same fridge in a warm kitchen, opened all afternoon, can spend half of it running.
Find your own fridge on that range. Enter the kWh per year from the yellow EnergyGuide label inside the door. The label is a floor: real use runs higher.
Adjust this plan to your house. Change the hours or the loads and the picks are re-scored here, with the same planner and the same maker figures.
How long each pick runs a refrigerator/freezer
| Model | Efficient, cool room about 54 W on average | Typical about 83 W on average | Old, warm room, door opened often about 130 W on average |
|---|---|---|---|
| EcoFlow DELTA 3 Ultra (3072Wh) | 36 h | 26 h | 18 h |
| EcoFlow DELTA Pro | 34 h | 26 h | 19 h |
Hours = what the battery gives back at the appliance’s average draw (running watts x share of time running), counting the power the station uses just to stay on. Method.
Where the energy goes, load by load
| Load | Hours | Running watts | share of time running | Energy | Share of worst case |
|---|---|---|---|---|---|
| Refrigerator/freezer | 24 | 100–700 | see note | 1,300–3,100 Wh | 100% |
Refrigerator energy comes from ENERGY STAR’s certified models plus our allowance for the station and real use, from an efficient new fridge to an old, big one: see how much power a fridge uses. The right-hand end of every row is what the plan is sized on.
A refrigerator alone for 24 hours, run against all 82 units we track: 34 clear at least the best case, 44 do not, and 4 could not be judged (a missing maker figure or an unclear recall status). Every figure is from the maker’s own page or manual; nothing here was tested by us. The method.

$1,299 at Amazon, November 1, 20263,072 Wh (2,520 usable)3,600 W continuous7,200 W peak72 lb
The EcoFlow DELTA 3 Ultra (3072Wh) holds 2,520 watt-hours you can use, more than the 2,000 a typical fridge needs in a day, so one charge covers it with no extra battery to buy. Among every power station we track that Amazon sells, it is the lowest price that does.
How we picked it: the cheapest unit that covers a typical day of this plan (2,000 Wh).
One charge covers a typical day of this plan (about 2,000 Wh). A hard-working refrigerator/freezer may need up to about 3,100 Wh.

Day two and three
Stretch this to three days (72 hours) of the same fridge and the target becomes 3,900 to 9,400 watt-hours. One charge of the DELTA 3 Ultra (3072Wh) or the DELTA Pro covers about one typical day, not three. From the second morning on, you are working out how to refill the battery you own.
Hooking it up safely
The plug-in path is the plan on this page. The station sits indoors, the fridge, router and lamps plug into its outlets, and nothing touches the house wiring.
Wired loads are a different job. A well pump, a furnace or a whole circuit needs a transfer switch or a power inlet installed by a licensed electrician (which switch fits which station or generator). Never feed a station or a generator into a wall outlet: it backfeeds the line and can kill the crew restoring your power. The safety rules and pass-through and output quality.
Buying it right
A search for these models returns bundles, sibling models and the same unit under two prices. We link only a listing whose own title states the unit on its own with its exact battery and output. Match the model number on the label to this page. How we check a listing.
- EcoFlow DELTA 3 Ultra (3072Wh): we link the model on its own, checked November 1, 2026. We turned down 8 other listings (bundles, sibling models, repeats); see which and why.
- EcoFlow DELTA Pro: we link the model on its own, checked November 1, 2026. We turned down 8 other listings (bundles, sibling models, repeats); see which and why.
What this page can’t promise
We cannot see your fridge, and this page is only as good as the figure you feed it. The label is a floor, not a forecast.
Leaving a station switched on with nothing drawing still costs energy, and we could not pin that figure down for these picks. Nothing here was tested by us: the specifications are the makers' own.

Questions people ask
What size power station do I need to run a refrigerator?
For a typical fridge, one that holds about 2,000 watt-hours you can use, for a full day. The usable figure is less than the one on the box. An efficient fridge in a cool room needs as little as 1,300; an old one in a warm kitchen up to 3,100. Put your fridge's EnergyGuide figure in the calculator on this page.
How many watt hours does a refrigerator use per day?
Between 1,300 and 3,100 watt-hours a day: ENERGY STAR's figures for certified fridges, plus our allowance for the power station's own draw and real use. A new, efficient fridge sits near the bottom; an old, big one near the top. The calculator on this page turns your own EnergyGuide label into your figure, and that label is a floor rather than a forecast.
How long will a 1,000-watt-hour power station run a refrigerator?
Less than a day for a typical fridge, which needs about 2,000 watt-hours. A station gives you less than the figure on its box, so check the usable figure. An efficient fridge in a cool room needs as little as 1,300; the runtime table on this page shows each pick at three levels of use.
