A portable power station is a big rechargeable battery with an inverter and outlets built in. It makes no noise or exhaust and is safe to run indoors. That makes it the first piece of backup power most households should own, in an apartment or a house.
These are research-based picks, chosen from manufacturer specifications and published data. We do not test products. Every spec below was read from the maker's own product page on October 27, 2026, and we link that page on every card. We focused on LiFePO4 (lithium iron phosphate) models because every one of these makers rates its LiFePO4 packs for thousands of charge cycles (3,000–4,000 in the specs below), which matters for a device you may keep for a decade.
Battery size comes first
Capacity is measured in watt-hours (Wh). Output is measured in watts (W). You need enough watts to run everything at once and enough watt-hours to keep it running for as long as you want. A quick rule: add up watts × hours for each device, divide by 0.85 for inverter losses, and add about 20% headroom.
| Load | Typical watts | Assumed use | ≈ Wh per day |
|---|---|---|---|
| Full-size refrigerator | 150–400 W running | Compressor runs ~⅓ of the time (DOE method) | 1,000–1,600 |
| CPAP, no heated humidifier | 30–60 W | 8 hours | 240–480 |
| Wi-Fi router + modem | 10–20 W | 24 hours | 240–480 |
| 4 LED bulbs | 8–15 W each | 5 hours | 160–300 |
| Phone + laptop charging | 20–100 W | 3 hours | 60–300 |
Wattage ranges are from Champion's generator wattage chart and the DOE appliance list; the fridge figure uses DOE's divide-by-three duty-cycle method, and DOE's federal purchasing guidance lists 363.5 kWh a year (about 1.0 kWh a day) for one ENERGY STAR 18.1 cu ft model.

EcoFlow RIVER 3 Plus
SmallBest for Phones, router, lights and a few hours of CPAP in an apartment.
At about 10 lb, the RIVER 3 Plus is the easiest station here to keep charged in a closet and grab when the lights go out. It is LiFePO4, lists a sub-10 ms UPS switchover, and can be expanded to 858 Wh with an add-on battery later.
Strengths
- + Light enough to carry one-handed
- + UPS mode for a router or CPAP

Tradeoffs
- − 286 Wh is roughly 4 hours of a 60 W CPAP through AC (286 × 0.85 ÷ 60)
- − 600 W continuous won't start a fridge compressor reliably
- Note: X-Boost runs some higher-watt resistive devices at reduced power (up to 1,200 W per EcoFlow).
| Capacity | 286 Wh |
| AC output | 600 W continuous / 1,200 W surge |
| Battery | LiFePO4 (LFP) |
| Weight | 10.4 lb |

Jackery Explorer 2000 v2
LargeBest for A fridge plus a sump pump or window AC for most of a day.
Doubling to 2,042 Wh with 2,200 W continuous and 4,400 W surge, the Explorer 2000 v2 handles a fridge and a mid-size motor load together. Jackery says it is not expandable, so buy the capacity you need up front.
Strengths
- + 4,400 W surge for motor starts
- + Roughly 2 kWh in one 39.5 lb box
- + UPS switching under 20 ms
Tradeoffs
- − Not expandable
- − Solar input tops out at 400 W, so refilling 2 kWh from sun takes a long, clear day
- Note: Jackery states the 2000 v2 is not expandable.
| Capacity | 2,042 Wh |

- Note: 120/240 V with an L14-30R outlet; home-circuit integration requires an electrician-installed transfer switch or panel.
| Capacity | 4,096 Wh |
| AC output | 4,000 W continuous / 8,000 W surge |
| Battery | LiFePO4 (LFP) |
| Weight | 113.54 lb |

Specs from the manufacturer's page, checked Oct 27, 2026. Confirm details before you buy.
Also worth a look: the EcoFlow DELTA 2 Max (2,048 Wh, 2,400 W, expandable to 6 kWh) if you want a large unit that can grow, and the Anker SOLIX F3800 Plus (3,840 Wh, 6,000 W, 120/240 V) if your loads are bigger than the DELTA Pro 3's 4,000 W. Both are in our sizing quiz product list.
How we chose
- LiFePO4 chemistry for long rated cycle life. Every pick lists LiFePO4/LFP on the manufacturer page.
- Enough surge for real loads. Fridges, pumps and AC units draw two to three times their running watts for a moment at start-up; mid-size picks here list 2,400–3,600 W surge.
- A clear size ladder (~300 Wh, ~1 kWh, ~2 kWh and ~4 kWh), so you can match your own daily watt-hours.
- Recharge options. Solar input, fast AC charging and expansion batteries matter more in a long outage than in a short one.
- Specs we could verify. If the manufacturer page didn't state a spec, we left it out rather than guess.
Realistic runtime examples
Runtime = usable watt-hours ÷ average watts. Usable watt-hours are roughly capacity × 0.85 once inverter losses are included (a DOE-submitted Florida Solar Energy Center report models 0.84–0.93 depending on load).
| Station | Usable Wh (× 0.85) | Fridge at ~1.6 kWh/day | 60 W CPAP |
|---|---|---|---|
| 286 Wh (RIVER 3 Plus) | ≈ 243 | Not recommended (600 W) | ≈ 4 hours |
| 1,070 Wh (Explorer 1000 v2) | ≈ 910 | ≈ 13–14 hours | ≈ 15 hours |
| 2,042 Wh (Explorer 2000 v2) | ≈ 1,736 | ≈ 26 hours | ≈ 29 hours |
| 4,096 Wh (DELTA Pro 3) | ≈ 3,482 | ≈ 2 days | ≈ 58 hours |
The fridge column uses our conservative 1.6 kWh/day estimate; a newer, efficient fridge can run noticeably longer. Keeping the fridge door closed matters too: CDC says an unopened refrigerator keeps food safe for about 4 hours and a full freezer about 48 hours. See how to power a refrigerator during an outage.

Take the sizing quizBuying checklist
- Add your loads' running watts. Your station's continuous rating should be at least 20% higher.
- Find your largest motor (fridge, pump, AC) and check its starting watts against the station's surge rating.
- Multiply watts × hours for a day and compare with capacity × 0.85.
- Decide how you will recharge: wall (before the storm), solar, car, or a generator. See best solar generator kits.
- Check UPS switchover time if a router, computer or CPAP should stay on without a blip.
- For medical devices, read the station maker's guidance and talk to your device supplier. See CPAP backup power.
- Store it charged. Top it up every few months and before storm season.
When a power station isn't enough
Electric space heaters (750–1,500 W), central AC and electric water heaters drain even large batteries quickly. If those are must-haves, or your outages last a week or more, compare a dual-fuel generator or a hybrid setup in power station vs. generator. Anything wired into your panel (furnace blowers, 240 V well pumps) needs a transfer switch installed by a licensed electrician; see transfer switch and interlock basics.
FAQ
- Can I run a portable power station indoors?
- Yes. Battery power stations make no exhaust, so they can be used indoors, unlike fuel generators. Keep them ventilated, dry and away from heat sources, and follow the manufacturer's manual.
- Will a 1,000 Wh power station run a refrigerator?
- For most of a day, usually. A 1 kWh LiFePO4 unit gives roughly 900 usable watt-hours. A full-size fridge typically uses about 1.0–1.6 kWh a day, so expect around 13–22 hours depending on the fridge, and longer if you keep the door shut.
- Why LiFePO4?
- The LiFePO4 (lithium iron phosphate) stations in this guide are rated by their manufacturers for 3,000–4,000 charge cycles before capacity drops to 70–80%. For an emergency device you may keep for many years, a long rated cycle life is worth prioritizing.
- How do I keep it charged for an emergency?
- Store it charged, check it every few months, and top it up whenever a storm is forecast. Many stations can also be left plugged in and used in UPS/pass-through mode. Check your model's manual.
- Do you test these power stations?
- No. These are research-based picks built from manufacturer specs and published data. We link each manufacturer page so you can confirm specs yourself. See our editorial policy.
