Emergency backup power
Best Power Stations for Emergencies
The Anker SOLIX F3000 remains our top emergency power station for multi-day outages: its expandable 3kWh battery has enough output for a fridge plus other essentials. For shorter outages, the 1kWh Jackery Explorer 1000 v2 is the simple current pick. The Bluetti AC180 is the value pick.
- Best for: keeping a fridge, CPAP, and the essentials running indoors. No fumes or carbon monoxide, unlike a gas generator.
- Sizing: a 1kWh station covers the essentials for many hours; pair the station with a folding solar panel to bridge multi-day outages.
- Skip 1kWh if: outages in your area run days, not hours. Start at 3kWh expandable.
A power station is the simplest way to keep your essentials running when the grid goes down, with no fuel, no fumes, and no noise. The three current picks come first, followed by the retired Delta 2 for historical context and guidance on choosing the right capacity.

The picks in detail
Our top emergency power stations
Anker SOLIX F3000
Capacity: 3kWh, expandableOutput: High surge for big loadsBest for: Multi-day outages
When you want a power station that can carry your essentials through a multi-day outage, the Anker SOLIX F3000 is our top pick. It has a big 3kWh battery you can expand, plenty of output for a fridge and more at once, and durable LiFePO4 cells rated for years of use. It is the closest thing here to home backup.
What we like
- Large, expandable 3kWh capacity
- Strong output handles a fridge plus more
- Long-life LiFePO4 battery
Worth knowing
- Heavy, this is a stay-put unit
- Premium price for the capacity
Jackery Explorer 1000 v2
Capacity: 1kWhUse: Plug-and-play simpleBest for: First-time buyers
If you want something dead simple to keep in a closet for emergencies, the Jackery Explorer 1000 v2 is hard to beat. It is light for its capacity, easy to understand, and pairs cleanly with a Jackery solar panel for recharging during longer outages. A great no-stress first backup unit.
What we like
- Very easy to use and understand
- Lighter than many 1kWh rivals
- Pairs simply with solar for recharging
Worth knowing
- Not expandable like some rivals
- 1kWh limits long-outage runtime
Bluetti AC180
Capacity: 1.15kWhOutput: High surge headroomBest for: Value-focused backup
The Bluetti AC180 packs strong specs at a friendly price, which makes it a smart value pick for emergency backup. It has good surge headroom for starting up appliances, a solid LiFePO4 battery, and fast charging. If you want a lot of capable backup for the money, start here.
What we like
- Excellent capacity and output for the price

EcoFlow Delta 2 (retired)
Capacity: 1kWh, expandableCharging: Very fast AC rechargeStatus: No longer available
When it was available, the EcoFlow Delta 2 was our most-households pick for shorter outages. Its 1kWh expandable battery and fast AC charging describe that retired unit only. We keep those figures for historical comparison, not as a current emergency recommendation.
What we like
- Recharged quickly between outages
- Accepted an extra battery for more capacity
- Used LiFePO4 cells
Worth knowing
- No longer available on Amazon
- 1kWh alone was short for long outages
How to choose an emergency power station
Start by listing what truly matters during an outage. For most homes that is the fridge, some lights, phones, and maybe a CPAP or a medical device. Add up roughly how much energy those use in a day, and you will know whether a 1kWh unit is enough or whether you need 3kWh and the option to expand.
Pay attention to two numbers beyond capacity: surge output and recharge speed. Surge matters because a fridge or pump needs a jolt of power to start. Fast recharging matters because grid power often flickers back briefly, and a station that refills quickly is ready for the next round. Favor LiFePO4 batteries, which last far longer in years of standby use.
Who should skip a power station? If you need to run heavy loads like central AC or an electric range for days on end, a whole-home generator is the better tool. For keeping essentials alive quietly and safely indoors, a power station wins.
Frequently Asked Questions
What size power station do I need for a power outage?
It depends on what you must keep running. To power a fridge, some lights, and phones through a short outage, a current 1kWh-class station like the Explorer 1000 v2 or AC180 works well. For multi-day outages or to run more at once, step up to a 3kWh unit like the SOLIX F3000, ideally paired with solar to recharge.
Can a power station run a refrigerator?
Yes, most mid-size and larger stations can. A fridge needs a brief surge of power to start its compressor, so look for a unit with good surge headroom. A 1kWh station can run a typical fridge for many hours, and a larger one can keep it cold for a day or more between recharges.
Can I run a CPAP overnight?
Easily. A CPAP without the humidifier sips power, so even a 1kWh station can run it for several nights. Turn off the heated humidifier to stretch runtime dramatically. This makes a power station one of the most reliable ways to keep a CPAP going during an outage.
How do I recharge it during a long outage?
Pair the station with a folding solar panel so the sun refills it during the day. That is what turns a power station from a few hours of backup into something that can carry you through a multi-day outage. Recharging from a car or generator is also an option for many units.
How do I choose a portable power station for emergencies?
Start with what you must keep running, usually a fridge, phones, a few lights, and any medical device like a CPAP. Add up their watt-hours for a day, then pick a station with at least that much capacity and enough output watts to start the fridge. For outages that can last days, choose a LiFePO4 unit you can expand and recharge with solar.
How long will a power station last in an outage?
It depends on how much you run. A 1kWh station keeps the essentials going for many hours, often through a full night, while a larger expandable unit paired with solar can bridge a multi-day outage. The trick is to run only what you truly need and refill from solar during daylight.
Can you run a portable power station indoors?
Yes, and this is its biggest advantage over a gas generator. A power station produces no carbon monoxide or fumes, so you can safely run it inside your home during an outage. A fuel generator, by contrast, must always stay outdoors and well away from windows and doors.
