The short answer
For most homes, the best portable power station for outage backup is one with at least 2,000Wh of LiFePO4 battery and 2,400–3,000 watts of output, which keeps a refrigerator, internet, lights and phones running through a typical overnight outage. The Jackery Explorer 2000 Plus (2,042Wh, 3,000W continuous, expandable to about 12kWh) is our top all-round pick. If you want to back up part of your home panel or run a 240V well pump, step up to the EcoFlow DELTA Pro 3 (4,096Wh, 120/240V, works with a transfer switch) or the Anker SOLIX F3800 (3,840Wh, 6,000W at 120/240V).

Specs are manufacturer ratings. Usable capacity is lower than rated capacity because of inverter losses.
How we picked
We compared manufacturer specifications, owner reviews and published reviews. For home backup, the factors that matter most are usable capacity (watt-hours), continuous and surge output, battery chemistry and cycle life, expandability, solar input for multi-day outages, 240V capability, and whether the unit can connect safely to your home through a transfer switch, inlet or the brand’s smart panel.
1. Jackery Explorer 2000 Plus — Best overall
The 2000 Plus hits the sweet spot for essentials backup. It has a 2,042Wh LiFePO4 battery with 3,000 watts continuous and 6,000 watts surge, enough to start and run a refrigerator, freezer, router and lights, and it’s expandable to about 12kWh with add-on battery packs. Jackery rates the battery for up to 4,000 cycles to 70% capacity and cites a full solar recharge in about 2 hours with six 200W panels in good sun.
Good to know: at 61.5 pounds it’s movable but not light. Cloudy post-storm days slow solar charging considerably.
Choose it if: you want to keep the kitchen and internet running through overnight outages, and you may expand later.

2. EcoFlow DELTA Pro 3 — Best for home circuits
The DELTA Pro 3 is built to back up your house, not just plug-in appliances. EcoFlow lists 4,096Wh of LFP capacity (expandable to 12kWh per unit with two extra batteries), 4,000 watts continuous (6,000 with X-Boost) and 8,000 watts surge, and 120/240V split-phase output, though it outputs either 120V or 240V in a session, not both at once. It works with EcoFlow’s Smart Home Panel 2 (professional installation) and also supports an inlet box or manual transfer switch. EcoFlow lists a 10 ms UPS switchover, up to 2,600W of solar input and 4,000 cycles to 80% capacity.
Good to know: it weighs about 113.5 pounds; it has wheels, but plan a permanent spot. Panel connection must be done by a licensed electrician.

3. Anker SOLIX F3800 — Most output
The F3800 delivers 6,000 watts continuous at 120V or 240V from a 3,840Wh LFP battery, enough to start a 240V well pump or feed a home panel through an inlet. It’s expandable to 53.8kWh with additional batteries and accepts up to 2,400W of solar.
Good to know: high output drains the battery fast. A steady 4,000-watt load would empty 3,840Wh in under an hour, so size your expansion around what you’ll actually run.

4. EcoFlow DELTA Pro — Best previous-gen value
The original DELTA Pro is still a capable home-backup battery: 3,600Wh LFP, 3,600 watts continuous and 7,200 surge, expandable to about 25kWh with extra batteries or EcoFlow’s Smart Generator, and up to 1,600W of solar input. EcoFlow rates it for 3,500 cycles to 80% capacity. Two units linked with a Double Voltage Hub can feed a panel through a transfer switch.
Good to know: it weighs about 99 pounds, and a single unit doesn’t provide 240V on its own.

5. EcoFlow DELTA 2 Max — Best mid-size
The DELTA 2 Max packs 2,048Wh of LFP into a 50-pound unit with 2,400 watts continuous (3,400 with X-Boost) and 4,800 surge across six AC outlets. It expands to 6,144Wh with two extra batteries, takes up to 1,000W of solar across two ports, and is rated for 3,000 cycles to 80%. EcoFlow also lists an “AC Always On” mode for outages.
Good to know: 120V only, so it won’t run 240V well pumps or connect to a panel for whole-circuit backup.

6. BLUETTI AC180 — Best compact
For short outages, apartments or a CPAP and router, the AC180 is a lighter, cheaper option: 1,152Wh LiFePO4, 1,800 watts continuous, 2,700 watts surge in Power Lifting Mode, up to 500W solar and 3,500+ cycles to 80%. It weighs about 35 pounds.
Good to know: it’s not sized for a full-size refrigerator over a long outage. Treat it as an essentials and electronics backup.

How much capacity do you need?
Runtime is simple math: usable watt-hours divided by your average load in watts. Allow for about 15% inverter loss.
| What you want to run | Typical average draw | Capacity for about 12 hours |
|---|---|---|
| Router, phones, a few LED lights | 50–100W | 1,000Wh |
| Above plus CPAP | 100–150W | 1,000–2,000Wh |
| Refrigerator, router, lights, phones | 150–300W (fridge cycles on and off) | 2,000–4,000Wh |
| Above plus freezer and furnace blower | 400–700W | 5,000Wh+ (expansion batteries) |
| 240V well pump plus essentials | Varies widely | 240V unit (DELTA Pro 3 or F3800) with expansion |
Check output too: the station’s continuous rating must exceed everything running at once, and its surge rating must cover motor startups like a fridge compressor or pump.
Power station or generator?
Power stations are silent, fume-free and safe indoors, and need almost no maintenance. Generators make far more total energy as long as you have fuel. For short outages and essentials, a power station is easier; for multi-day outages with heavy loads, a dual-fuel generator such as the Westinghouse WGen9500DF is cheaper per watt. Many households pair a power station with a small inverter generator to recharge it.
Buying checklist
- LiFePO4 (LFP) chemistry for long cycle life and better thermal stability.
- Capacity and output both sized to your loads.
- Expandability if you might want longer runtime later.
- Solar input for multi-day outages; check the panel wattage and voltage limits.
- UPS or fast switchover if you’re protecting a CPAP, computer or network gear.
- Home connection: use the brand’s smart panel, a transfer switch or an inlet box installed by a licensed electrician. Never backfeed through an outlet.
- Weight and wheels if you’ll move it between rooms.
FAQ
Can a portable power station run a refrigerator?
Yes. A unit with 2,000Wh or more and at least 1,800–2,400 watts of output can typically run a full-size fridge for many hours, depending on how often the compressor cycles.
Can a power station power my whole house?
Not on its own for most homes. Large 240V units like the EcoFlow DELTA Pro 3 or Anker SOLIX F3800, connected through a transfer switch and expanded with extra batteries, can back up selected circuits.
Is it safe to use a power station indoors?
Yes. Power stations produce no exhaust, so they can run inside. Keep vents clear and follow the manufacturer’s placement guidance.
How long do power station batteries last?
LiFePO4 models are typically rated for 3,000–4,000 or more cycles before dropping to 70–80% of original capacity, which is many years of occasional backup use.
