The best portable power stations for home backup

We picked it because it is the lowest-priced way to cover a typical day of this plan, counting its extra battery, among units with no recall.

An efficient fridge with Wi-Fi, lights and phones needs about 1,738 watt-hours over the day. An older fridge running hard needs 5,116, which no single unit covers on one charge, so plan on extra batteries or solar. Buy the EcoFlow DELTA Pro 3 ($2,799 at Amazon).

A fridge, the internet, a few lamps and everyone's phones through a day without the grid, indoors, with no engine to run. Sized on the harder end of every range.

Who this is for

You want a fridge, the router, a few lamps and everyone's phones to survive an outage measured in hours to a day, indoors, without a generator to start or fuel to store. You can lift a heavy suitcase or you have someone who can. You are not trying to run a well pump, a furnace blower or central air; those are wired jobs and a different page.

How much battery you need

1,738Wh, best case

5,116Wh, worst case: buy for this

860W running, worst case

3,060W starting surge

The whole plan hangs on the fridge. Wi-Fi, lights and phones together barely register; the compressor is most of the energy and all of the starting surge. A new, efficient fridge in a cool kitchen with the door mostly shut runs about a fifth of the time and needs 1,738 watt-hours over the day. An older fridge in a warm kitchen, opened often, runs half the time and needs 5,116. That is not a rounding difference; it is the difference between a battery you carry in one hand and one you wheel.

Every dark block is the compressor running at 100–700 W. Energy is watts × the share of the day it runs, which is why the same fridge can need 1,300 or 3,100 Wh in a day.

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.

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	61%
Wi-Fi router and modem	24	15–40	100%	360–960 Wh	19%
Phone charging and small USB devices	24	10–40	20–60%	48–576 Wh	11%
A few LED lights	8	15–80	25–75%	30–480 Wh	9%

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. For every other load, energy = running watts × share of time running × hours, at each end of the range. The right-hand end of every row is what the plan is sized on.

A refrigerator, Wi-Fi, a few LED lights and phone charging for 24 hours, run against all 82 units we track: 20 clear at least the best case, 58 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.

The EcoFlow DELTA Pro 3 holds the most usable energy of the three on its own and names its extra battery, the DELTA Pro 3 Smart Extra Battery.

How we picked it: the cheapest unit that covers a typical day of this plan (2,900 Wh).

One charge covers a typical day of this plan (about 2,900 Wh). A hard-working refrigerator/freezer may need up to about 5,100 Wh.

Day two and three

Three days needs 5,214 to 15,448 watt-hours. No portable battery we track covers the top of that, and only the two big picks cover the bottom of it. Past the first day the plan is a refill: panels in the sun, an alternator charger in the car, or a generator running outside feeding the station indoors.

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 Pro 3: 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

The fridge decides this plan. An old fridge in a warm kitchen can need several times the energy of a new one in a cool room with the door kept shut, which is why every pick covers the best case and none covers the worst. Know which end your own fridge sits on before you buy.

Nothing on this page is a hands-on test. The figures are the makers' own, read from their pages and manuals and linked under each pick; what owners report comes from public threads and long-term reviews and is labelled as such. Where a maker's marketing page and its printed manual disagree, we say so rather than pick the better number.

Questions people ask

What size power station do I need for a fridge, internet and lights?

Plan for 5,116 watt-hours in the worst case and a starting surge of 3,060 watts. The best case is 1,738 watt-hours; the gap between the two is your fridge's age and your kitchen's temperature.
