Refrigerator backup
Tell us the kind of fridge and how long you need it. We’ll suggest a battery size and show the four power stations that come closest.

What kind of fridge? How long should it run? Which of these four batteries is close?
Four models. Tap a button to see the current price on the maker’s site.
EcoFlow
Smaller battery for a short outage or a lower-energy freezer.
1,024 Wh

1,024 Wh capacity. 1,800 W continuous. 3,600 W published surge.
Spec block matched 1,024 Wh, 1,800 W total, and 3,600 W surge. The same page also describes an X-Boost figure of 2,200 W, which is not the continuous rating used here.
Jackery
Close in size to the DELTA 3 Plus. The published capacity used here is 1,070 Wh.
1,070 Wh

1,070 Wh capacity. 1,500 W continuous. 3,000 W published surge.
A specifications row matched 1,070 Wh, 1,500 W rated, and 3,000 W surge. A description sentence on the same page says 1,024 Wh. This site did not replace 1,070 Wh.
Jackery
One of the two larger batteries, at 2,042 Wh.
2,042 Wh

2,042 Wh capacity. 2,200 W continuous. 4,400 W published surge.
Official text matched 2,042 Wh, 2,200 W continuous, and 4,400 W surge. The manufacturer’s refrigerator wording on that page is not a test by this site.
EcoFlow
The largest battery in this list, at 2,048 Wh.
2,048 Wh
Check price at EcoFlow (opens in a new tab)
2,048 Wh capacity. 2,400 W continuous. 4,800 W published surge.
Official text matched 2,048 Wh, 2,400 W output, and 4,800 W surge. An X-Boost mention of appliances up to 3,400 W is not used as the continuous or surge rating.
Top freezer, side-by-side, chest, or “I’m not sure.” You do not need the brand.
Overnight, half a day, or a full day. Longer means a bigger battery.
We show the watt-hours to plan for, and which of the four published batteries come closest.
These are estimates. Real runtime depends on your fridge, its age, and how often it's opened.
