Last fact-checked
This guide is for people buying their first portable power station because the grid where they live is unreliable. We compared five units on the four specifications that decide outage performance: inverter output, usable capacity, recharge speed and UPS switchover time. We did not test these units ourselves, and each review states exactly what its recommendation is based on. What you will get here is the runtime arithmetic manufacturers leave out, an explanation of why surge-rating modes do not apply to a refrigerator, and a clear line between the 120V units most people need and the 240V systems most people do not.
What is the best portable power station for home backup?
The Anker SOLIX C1000 suits the widest range of households. Its 1800W inverter starts a full-size refrigerator, it refills to 80% in under an hour between outages, and it switches over fast enough to keep a desktop running. If you have 240V loads such as a well pump, the Anker SOLIX F3800 is the only unit here that can drive them.
Key takeaways
- Inverter output decides whether a unit can start a refrigerator; capacity only decides how long it runs afterwards
- Recharge speed matters more than most buyers expect, because outages often come in short bursts with grid windows between them
- Surge modes such as X-Boost and Power Lifting reach their headline wattage by lowering voltage, so they do not apply to motors
- A 1000Wh unit runs a fridge for six to seven hours, not a weekend, whatever the runtime chart implies

Best overall
Anker SOLIX C1000
Anker
The C1000 covers the most common outage jobs without pushing you into a heavier class. It carries a genuine 1800W inverter, sub-20ms UPS switchover and a 58-minute recharge to 80%, which is the combination that matters when power comes back intermittently.
What we like about the Anker SOLIX C1000
- 1800W inverter starts a full-size fridge compressor, not just electronics
- Recharges to 80% in 58 minutes, so it can refill during short grid windows
- Sub-20ms UPS switchover keeps a desktop or router alive through a cut
- Expandable to 2112Wh later without replacing the unit
Where it falls short for the Anker SOLIX C1000
- The 1056Wh pack runs a 150W fridge for roughly six to seven hours, so a multi-day outage needs solar or a second battery
- Only one expansion battery is supported, which caps the ceiling well below the F3800 class
- The 58-minute fast charge drives the internal fan hard and is audible across a quiet room
- No 240V output, so well pumps and electric ranges are out of scope entirely
Key specifications
- Capacity
- 1056Wh
- AC output
- 1800W (2400W SurgePad)
- UPS switchover
- Under 20ms
- AC recharge time
- 58 minutes to 80%
- Weight
- 28.4 lb (12.9 kg)
- Expandable
- Yes, to 2112Wh with one expansion battery
The C1000 sits at the point where a portable power station stops being a gadget and starts being outage equipment. The dividing line is the inverter, not the battery.
Why the inverter rating decides this category
A 1000W inverter looks adequate on paper for a fridge that draws 150W while running. It usually is not. Compressors pull a large surge at start-up, and that surge is what trips undersized inverters. The 1800W continuous rating, with SurgePad lifting it to 2400W, leaves enough headroom that a full-size fridge starting is a non-event.
That is the practical reason this unit leads the guide rather than the EcoFlow DELTA 2, which carries the same 1800W rating but refills more slowly.
What the recharge time actually buys you
Outages are rarely clean. Power comes back for twenty minutes, drops again, then returns for an hour. A unit that needs three hours to refill cannot use those windows. One that reaches 80% in under an hour can.
This is the most underrated specification in the category, and it is why the C1000 and the BLUETTI AC180 are the two units here we would pick for genuinely unreliable grids.
Where it runs out
At 1056Wh, arithmetic sets the ceiling. A fridge averaging 150W across a full duty cycle draws roughly 3.6kWh a day. The C1000 holds under a third of that. It will carry a fridge through an evening and a night. It will not carry one through a weekend without solar input or a second battery.
One expansion battery takes it to 2112Wh. That helps, but it is still a different category from the F3800, and anyone planning for multi-day outages should read that section instead.
- Best for
- Households that want one unit to cover a fridge, medical device, internet and lighting through outages measured in hours rather than days.
- Choose something else if
- You need to run 240V appliances such as a well pump, or you expect outages lasting more than about a day with no way to recharge.
Best for fast recharge
BLUETTI AC180
BLUETTI
The AC180 refills to 80% in 45 minutes, the quickest turnaround in this guide, and pairs that with a 1800W inverter and a 3,500-cycle rating. The trade is weight: at 35.3 lb it is the heaviest unit here that a person still carries by hand.
What we like about the BLUETTI AC180
- 45 minutes to 80% is the fastest recharge in this comparison
- 3,500 rated cycles to 80% is the longest service life among the sub-1200Wh units here
- 1800W inverter handles the same fridge and pump loads as our top pick
- Sub-20ms UPS switchover suits desktops and network gear
Where it falls short for the BLUETTI AC180
- At 35.3 lb it weighs 7 lb more than the C1000 for only 96Wh more capacity
- Not expandable, so the 1152Wh ceiling is permanent and buyers outgrow it
- Power Lifting reaches 2700W by reducing voltage and works only with resistive loads, so that figure never applies to a fridge or pump
- The wraparound handle makes it awkward to carry one-handed through a doorway
Key specifications
- Capacity
- 1152Wh
- AC output
- 1800W (2700W Power Lifting)
- AC recharge time
- 45 minutes to 80%
- Rated cycle life
- 3,500 cycles to 80%
- Weight
- 35.3 lb (16.0 kg)
- UPS switchover
- Under 20ms
The AC180 wins a narrow but real category: it is the unit to buy when your problem is frequency rather than duration.
The Power Lifting caveat matters
BLUETTI advertises 2700W through Power Lifting, and that number appears in most retail listings. It carries a condition that is easy to miss. Power Lifting works by reducing output voltage to keep current within limits, which is fine for a resistive load such as a kettle or a heater element. It does not work for anything with a motor.
The honest figure for a fridge, a pump or a power tool is therefore 1800W, the same as the C1000. Anyone choosing this unit specifically for the bigger headroom number is buying something that will not apply to the load they had in mind.
The weight problem
At 35.3 lb the AC180 is the heaviest hand-carried unit here. It holds 96Wh more than the C1000 and weighs 7 lb more. That is a poor exchange rate, and it is the main reason this is not our overall pick.
If the unit lives in a utility room and only moves during an outage, the weight is irrelevant. If it moves between a house and a vehicle, it is the first thing you will notice.
No expansion path
The AC180 cannot take an expansion battery. What you buy is what you keep. For a household with stable needs that is fine. For anyone whose plan might grow to cover a second appliance, the DELTA 2 and the C1000 leave a door open that this unit closes.
- Best for
- Homes on a grid that fails often but briefly, where refilling between cuts matters more than absolute capacity.
- Choose something else if
- You will carry the unit regularly, or you expect your power needs to grow, because there is no expansion path at all.
Best for whole-home and 240V loads
Anker SOLIX F3800
Anker
The F3800 is the only unit here that outputs 240V split phase, which is what a well pump, an electric range or a central air handler needs. It is also 132 lb and priced in a different bracket, so it is a different kind of purchase entirely.
What we like about the Anker SOLIX F3800
- 120V and 240V split-phase output covers well pumps and electric ranges, which no other unit here can do
- 3840Wh base capacity runs a fridge for roughly a full day before recharging
- Expandable to 26.9kWh, so it grows into a genuine whole-home system
- 2400W solar input can refill it in a single good day off-grid
Where it falls short for the Anker SOLIX F3800
- At 132 lb it needs two people or the built-in wheels, and it will not go up stairs easily
- Transfer-switch installation for true whole-home backup is an electrician job with real cost on top of the unit
- The wheels and pull handle are useless on gravel, grass or a step, so placement is close to permanent
- Overkill for the fridge-and-internet outage most buyers are actually planning for
Key specifications
- Capacity
- 3840Wh
- AC output
- 6000W
- Ports
- 13 total, including 30A RV and 120V/240V split phase
- Max solar input
- 2400W
- Weight
- 132 lb (60 kg)
- Expandable
- Yes, to 26.9kWh with expansion batteries
The F3800 is where the category stops being portable in any ordinary sense and becomes installed equipment that happens to have wheels.
The 240V question decides everything
Every other unit in this guide outputs 120V only. That covers a fridge, lighting, electronics, a CPAP machine and most small appliances. It does not cover a well pump, an electric range, a dryer or a central air handler, because those are 240V loads.
If you are on a well, this is the practical shortlist of one. If you are on municipal water and heat with gas, the 240V capability is a feature you will pay for and never use.
What whole-home actually requires
Running a house from this unit rather than running extension cords means a transfer switch, and that means an electrician. The cost varies by region and by how your panel is laid out, but it is a real line item that listings do not mention.
Buyers who skip that step end up with a very expensive unit powering the same three extension cords a C1000 would have handled.
The portability claim
132 lb with integrated wheels sounds manageable. On a flat garage floor it is. On gravel, grass, or across a single step it is not, and owner reports are consistent on this point. Treat the placement as close to permanent and plan where it will live before buying.
- Best for
- Homes with 240V loads such as a well pump, or anyone planning multi-day outage coverage rather than a few hours.
- Choose something else if
- Your outage plan is a fridge, phones and internet, in which case you are paying for capacity and voltage you will never use.
Best expandable mid-range
EcoFlow DELTA 2
EcoFlow
The DELTA 2 matches our top pick on inverter output and beats it on expansion, reaching 3040Wh against the C1000 ceiling of 2112Wh. It gives up recharge speed and a slightly slower UPS switchover to get there.
What we like about the EcoFlow DELTA 2
- Expandable to 3040Wh, the widest growth path of the hand-carried units here
- 1800W inverter handles fridge start-up surges
- 15 ports including six AC outlets, the most connection options in this guide
- At 27 lb it is the lightest of the 1000Wh-class units here
Where it falls short for the EcoFlow DELTA 2
- 80 minutes to full is noticeably slower than the 45 to 58 minutes of the AC180 and C1000
- 30ms UPS switchover is slower than the sub-20ms rivals and is marginal for some desktop power supplies
- X-Boost reaches 2700W by lowering voltage and does not apply to motor loads, so the usable figure for a fridge is 1800W
- Expansion batteries cost a large fraction of a second complete unit, which weakens the value of the upgrade path
Key specifications
- Capacity
- 1024Wh
- AC output
- 1800W (2700W X-Boost)
- Expandable
- Yes, to 3040Wh with extra batteries
- AC recharge time
- 80 minutes to full
- UPS switchover
- Under 30ms
- Ports
- 15 total, 6 AC outlets
The DELTA 2 is the unit for buyers who know their needs will change.
Expansion is the real argument
Every unit in this guide has a capacity ceiling. The DELTA 2 has the highest one you can reach without moving to the 132 lb F3800 class. Adding batteries takes it from 1024Wh to 3040Wh, roughly triple, while the C1000 tops out at double.
That matters if you are buying now for a fridge and expect to add a second appliance or longer coverage later.
The counterargument on cost
Expansion batteries are not cheap. By the time you have added one, you are inside touching distance of what a second complete unit would cost, and a second unit gives you a second inverter and the ability to power two separate locations.
Buyers should price the full expanded configuration before treating the upgrade path as the deciding factor. It is a real advantage, but it is not free.
Where it loses to the top pick
Recharge speed. Eighty minutes to full against 58 minutes to 80% is a meaningful gap when the grid is flickering. And the 30ms switchover, while fine for most equipment, is slower than the sub-20ms figures on the C1000 and AC180 and sits at the edge of what some desktop power supplies tolerate.
If your grid is stable and you are buying for a planned, single long outage, none of that matters and the expansion path wins. If your grid is unreliable, the C1000 is the better tool.
- Best for
- Buyers who expect their power needs to grow and want to add capacity in stages rather than replace the unit.
- Choose something else if
- You need the fastest possible refill between short outages, or you are protecting a desktop that is sensitive to switchover time.
Best lightweight option
Jackery Explorer 1000 v2
Jackery
At 23.8 lb the Explorer 1000 v2 is the easiest unit here to move between rooms or into a car, and its 4,000-cycle rating is the longest in the guide. The 1500W inverter is the compromise, and it is the one that rules out some fridges.
What we like about the Jackery Explorer 1000 v2
- 23.8 lb is 4 lb lighter than the DELTA 2 and 12 lb lighter than the AC180
- 4,000 cycles to 70% is the longest rated service life in this comparison
- 1070Wh is the largest capacity of the sub-25 lb units here
- Straightforward interface with no mode settings to misread under pressure
Where it falls short for the Jackery Explorer 1000 v2
- The 1500W inverter is 300W below the rest of the shortlist and will not start some full-size fridge compressors
- No expansion path, so 1070Wh is permanent
- Three AC outlets is the fewest here and forces a power strip for a typical outage setup
- No published UPS switchover specification, so it should not be relied on for equipment that cannot tolerate a brief cut
Key specifications
- Capacity
- 1070Wh
- AC output
- 1500W (3000W surge)
- Weight
- 23.8 lb (10.8 kg)
- Rated cycle life
- 4,000 cycles to 70%
- AC recharge time
- 1.7 hours to full
- Ports
- 7 total, 3 AC outlets
The Explorer 1000 v2 is the unit you buy when the thing you are optimising for is carrying it.
Weight is a real specification
Twenty-four pounds against thirty-five is the difference between a unit that moves easily and one that stays where you put it. For a household that wants the same unit for outages and for camping, or for anyone who cannot comfortably lift 35 lb, this is the practical choice.
It also holds more capacity than anything else near its weight.
The inverter is the catch
1500W continuous is 300W below every other unit in this guide. For electronics, lighting, a router and a CPAP machine that gap is irrelevant. For a full-size refrigerator it may not be.
Compressor start-up surge varies by fridge. Many will start on 1500W. Some will not, and there is no way to know which category yours is in without trying it. That uncertainty is why this unit is the lightweight pick rather than the overall one.
Read the cycle rating carefully
Jackery quotes 4,000 cycles, which is the biggest number in this guide. It is measured to 70% remaining capacity, while Anker, EcoFlow and BLUETTI quote to 80%. A lower threshold means more cycles counted, so the figures are not directly comparable.
The unit does appear to have a long service life. It is just not four thousand against three thousand in the way the listings imply.
- Best for
- People who need to carry the unit regularly, or whose outage load is electronics, lighting and a CPAP machine rather than a large fridge.
- Choose something else if
- A full-size refrigerator is the main thing you are protecting, since the 1500W inverter may not start it reliably.

Which one should you buy?
Match your situation on the left to the recommendation on the right.
-
You have a well pump, an electric range or a central air handler
Recommendation: Buy the Anker SOLIX F3800, the only unit here with 240V split-phase output
-
Your grid fails often but power returns within an hour or two
Recommendation: Buy the BLUETTI AC180 for its 45-minute refill to 80%
-
You want one unit for a fridge, internet and lighting
Recommendation: Buy the Anker SOLIX C1000
-
You expect to add appliances or longer coverage later
Recommendation: Buy the EcoFlow DELTA 2 for its 3040Wh expansion path
-
You need to move the unit between rooms or into a car regularly
Recommendation: Buy the Jackery Explorer 1000 v2 at 23.8 lb, but check your fridge starts on 1500W
Mistakes buyers make
- Sizing by capacity alone and buying a unit whose inverter cannot start the refrigerator it was bought for
- Trusting the headline surge figure without checking that it applies to motor loads rather than resistive ones
- Reading manufacturer runtime charts as outage planning, when they assume a constant draw rather than a compressor duty cycle
- Buying a 240V-capable unit for a house with no 240V loads, which is capacity and cost that will never be used
- Planning whole-home backup without budgeting for the transfer switch and the electrician to install it
Our final recommendation
If you want one answer rather than a shortlist, this is the unit that suits the widest range of readers in this category.
Best overall
Households that want one unit to cover a fridge, medical device, internet and lighting through outages measured in hours rather than days.
Questions buyers ask
Is it safe to run a portable power station indoors?
Yes. Unlike a fuel generator, a battery power station produces no exhaust, so there is no carbon monoxide risk and it can be used inside. Keep the vents clear, because these units run cooling fans hard while charging and under heavy load.
How long will one of these run my refrigerator?
A full-size fridge averages roughly 150W once you account for the compressor duty cycle, or about 3.6kWh across a day. A 1000Wh unit therefore covers six to seven hours. The 3840Wh F3800 covers around a day. Manufacturer runtime charts usually assume a constant low draw and overstate this.
Can a portable power station back up my whole house?
Only the F3800 class can, and only with a transfer switch installed by an electrician. The 120V units in this guide power individual appliances through extension cords or a dedicated circuit. They cannot feed a panel.
What does UPS switchover time mean and does it matter?
It is how quickly the unit takes over when grid power drops. Under 20ms is fast enough that a desktop computer or a router does not reboot. If you are only protecting a fridge and some lamps, switchover time is irrelevant, because those loads do not care about a brief gap.
Do these lose capacity in cold weather?
Yes, all lithium units do, and LiFePO4 packs also refuse to charge below freezing to protect the cells. A unit kept in an unheated garage through winter will deliver noticeably less than its rating and may not accept a charge at all until it warms up.
