The wind has been howling since dinner. At 9:40 the lights die, the fridge stops humming and the street goes dark. Your phone says the utility expects power back “within 48 hours.” Now the questions come fast: will the milk last, will the sump pump keep the basement dry, can you still run the CPAP tonight? A home backup power station answers those questions before the storm, not during it.

The best portable power station for home backup in 2026 is the EcoFlow DELTA Pro 3: 4,096 Wh, 4,000 W at 120 V and 240 V, and room to grow to 12 kWh with extra batteries. With an electrician-installed Smart Home Panel 2, it powers your house circuits. On a smaller budget, the EcoFlow DELTA 3 Max Plus keeps a fridge, Wi-Fi and lights going through a power outage.

Below: seven picks, what they can and can’t run, how long they last, and how to connect one safely.

Prices change often. The prices below are what we saw at the maker or a major retailer in October 2026; check the current price before you buy. Where we couldn’t confirm a current price, we left it out.

“240 V: No” means the maker lists only 120 V outlets on the specs we read. All seven use LiFePO4 batteries.

What a power station can and can’t run in an outage

A power station is a big battery with an inverter. It runs anything that plugs into a normal outlet, as long as the total watts stay under its output rating, until the battery is empty. Here’s a realistic split:

• Easy: the fridge and a chest freezer, Wi-Fi modem and router, LED lamps, phones and laptops, a TV, fans, a CPAP, a medicine fridge.
• Possible with a big unit: a 120 V sump pump (it needs high starting power), a microwave or coffee maker for short bursts, a window air conditioner (check its label watts; it will drain the battery fast).
• Needs a transfer switch or home panel: anything hard-wired, like a gas furnace’s blower and controls, a well pump (often 240 V) or a garage door opener on its own circuit.
• Not practical: electric water heaters, electric ranges, dryers and electric heat. They draw thousands of watts for hours. EcoFlow says the DELTA Pro 3 can run a 3-ton central AC, but expect hours, not days.

How long will it last? An outage-day budget

We add up a day of essentials and divide each station’s usable energy by it, counting about 85% of rated capacity as usable (the inverter uses some): usable Wh ≈ capacity × 0.85. Fridges and freezers cycle on and off, so we use their yearly kWh, not their nameplate watts.

Device (source of the number)	Energy per day
Full-size top-freezer fridge (median ENERGY STAR model, 363 kWh/year)	≈995 Wh
Chest freezer (median ENERGY STAR full-size model, 218 kWh/year)	≈600 Wh
Modem and router, 20 W together (example; check your adapters’ labels), 24 hours	≈480 Wh
Five 9 W LED bulbs, 5 hours each (bulb label)	≈225 Wh
Laptop on a 65 W charger, 2 hours (adapter label)	≈130 Wh
ResMed AirSense 11 CPAP, 8 hours at its typical 56.1 W (ResMed user guide)	≈450 Wh
Zoeller M53 sump pump: 9.7 A × 115 V ≈ 1,116 W, if it runs 1 hour in total (Zoeller specs)	≈1,116 Wh

Station (usable Wh)	Fridge, Wi-Fi, lights, laptop (≈1,830 Wh/day)	+ freezer and CPAP (≈2,880 Wh/day)	+ sump pump (≈4,000 Wh/day)
DELTA 3 Plus (≈870)	≈11 hours	≈7 hours	≈5 hours
2 kWh class (≈1,740)	≈23 hours	≈14 hours	≈10 hours
F3800 Plus (≈3,260)	≈1.8 days	≈27 hours	≈20 hours
DELTA Pro 3 (≈3,480)	≈1.9 days	≈29 hours	≈21 hours
Explorer 5000 Plus (≈4,280)	≈2.3 days	≈1.5 days	≈26 hours
DELTA Pro 3 + 2 extra batteries (≈10,440)	≈5.7 days	≈3.6 days	≈2.6 days

These are our estimates, not maker figures; cold, an older battery or a busier sump pump shorten them. A compressor or pump motor also pulls a brief starting surge, so leave headroom. Two tricks stretch any battery. Ready.gov says a closed fridge keeps food cold for about four hours and a full freezer holds its temperature for about 48 hours, so you can run them in shifts. And solar panels can refill the battery during the day.

For a CPAP or any medical device, talk to your doctor or equipment supplier about an outage plan first. ResMed advises turning off humidification when running on battery power. Jackery says its power stations are not recommended for medical devices or life-support equipment.

How to connect a power station to your home safely

There are three ways to use a power station in an outage; only the first needs no professional help.

1. Extension cords to each appliance. Plug the fridge, lamp and router straight into the station, with heavy-duty cords where needed. No installation; it’s how most people start.
2. A transfer switch or power inlet. A licensed electrician installs a manual transfer switch next to your panel, often with an outdoor inlet box. You plug the station into the inlet and flip the circuits you chose (fridge, furnace, well pump, lights). Stations with an L14-30 outlet, like the DELTA Pro 3, Explorer 5000 Plus and F3800 Plus, are made for this. Ask the electrician to check the station maker’s instructions on 240 V and neutral grounding before choosing a switch.
3. A maker’s home panel. EcoFlow’s Smart Home Panel 2, Jackery’s Smart Transfer Switch and Anker’s Home Power Panel switch your chosen circuits over automatically when the grid fails. Jackery says its switch moves 12 essential circuits in 20 ms or less with UPS enabled. These are installed products: EcoFlow says its panel requires installation, and Jackery offers installation through certified electricians.

Never “backfeed” your house by plugging a generator or power station into a wall outlet with a double-ended cord. FEMA warns never to plug a generator into a wall outlet: the power can flow back out onto the lines and electrocute utility workers or neighbors. Any connection to house wiring should go through a transfer switch or panel installed by a licensed electrician, with a permit where your town requires one.

A power station makes no exhaust, so it’s safe inside. If you recharge it from a gas generator, CPSC says to run the generator outdoors only, at least 20 feet from the house, never in a garage, and to keep carbon monoxide alarms working inside.

How to choose a power station for home backup

• Start with your must-run list. Fridge, Wi-Fi, lights and phones need about 1,800 Wh a day in our example; a CPAP, freezer or sump pump adds more. Size the battery for at least one day, then plan to recharge.
• Check output and surge. Add the running watts of everything on at once, and leave headroom for motor start-ups.
• Do you need 240 V? Well pumps and some furnaces and air conditioners do. That points to the DELTA Pro 3, Explorer 5000 Plus or F3800 Plus, plus an electrician.
• Look at UPS switchover. A 10 to 20 ms switchover (maker figures, measured differently by each) keeps a router or computer running through a flicker.
• Plan the recharge. Solar input watts decide how much you can refill on a sunny day. Keep the unit indoors in winter: Battery University notes lithium batteries can’t be charged below freezing.

There’s no federal tax credit for portable power stations or home batteries in 2026; the 25D residential clean energy credit ended for installations completed after December 31, 2025. Check DSIRE for state and utility programs.

Home backup power station questions

What is the best portable power station for a power outage?

For whole-home essentials, the EcoFlow DELTA Pro 3: 4,096 Wh, 120/240 V and expandable to 12 kWh. For a fridge, Wi-Fi and lights, a 2 kWh unit like the EcoFlow DELTA 3 Max Plus lasts about a day by our estimate. For short outages and small electronics, the EcoFlow DELTA 3 Plus is enough.

Can a portable power station power a whole house?

Not in the normal sense. Even a 5 kWh unit covers essentials for a day or two, not electric heat, water heating and cooking. Large expandable systems connected through a transfer switch or maker panel can run selected circuits, including 240 V ones, for several days if you limit what’s on and recharge with solar.

Can I plug a power station into a wall outlet to power my house?

No. Feeding power into a wall outlet, called backfeeding, can send electricity back onto utility lines and injure line workers, and it’s a fire risk at home. FEMA says never to plug a generator into a wall outlet. Use extension cords to individual appliances, or have a licensed electrician install a transfer switch or the maker’s home panel.

Will a portable power station run a sump pump?

Often, yes, if it’s a 120 V pump and the station has enough output and surge. A Zoeller M53, for example, draws 9.7 A at 115 V, about 1,116 W while running, and more for a moment at start-up. A 2,400 W or bigger station gives comfortable headroom. In heavy rain the pump may cycle a lot, so plan on a large battery.

Can I run my CPAP on a power station during an outage?

Many people do, but talk to your doctor or equipment supplier first and check your machine’s watts and DC options. ResMed lists the AirSense 11 at 56.1 W typical and advises turning off humidification on battery. Jackery says its stations aren’t recommended for medical devices. A spare plan, like a charged backup battery, is wise.
