How we tag a power station

Fridge — a published surge rating of 1,000 W or more, enough to start a typical full-size fridge (where no surge figure is published we count the continuous rating).
CPAP all night — label Wh × 62% ÷ 40 W comes to 8 hours or more (the runtime chart’s arithmetic; for the two units Outdoor Life tested, their measured Wh at 34 W instead).
Microwave or heater — continuous output of 1,500 W or more, enough for a 1,500 W space heater (a 1,000 W microwave draws about 1,300 W).
240 V appliances — the maker lists 240 V output, from one unit or by pairing two.
Carry by hand — the listed weight is 25 lb or less.
UPS switchover — the maker lists a UPS switchover time of 30 ms or less.
Full in an hour — the maker lists a full AC recharge in 60 minutes or less.
Add-on batteries — the maker sells add-on batteries for it.
Low cost per Wh — the Amazon price on the card divided by the label Wh is under $0.50.

From maker spec pages and Amazon listing titles; † marks Outdoor Life’s measurements. No tag can simply mean we could not verify that figure (most gaps are on BLUETTI’s Elite 100 V2, AC180 and Elite 200 V2 and the ECO-WORTHY). Every unit here is LiFePO4, so chemistry isn’t a filter.

Cycles are each maker’s figure, to the remaining capacity shown: Jackery counts to 70%, the other makers here to 80%, and Anker also quotes the S2000 to 60%. Compare cycle counts only at the same end point. Every unit here is LiFePO4.

Usable capacity vs. label Wh: what came out of the outlet

TakeawayOvernight you keep about half to three-quarters of the label. Best: Grecell T1000 77%, Lion Energy Summit 72%, Goal Zero Yeti 700 70%. Worst: Jackery Explorer 1000 Plus 49%, Vtoman FlashSpeed 1500 50%. At a 380 W load the eleven units run at that load held 78–92% (the Oupes’s first run: 76%). The gap is the inverter running itself: by the middle of these results, a 1,000 Wh label gives about 600 Wh overnight and about 870 Wh at 380 W.

Measured by Outdoor Life, published 9 January 2026: each unit ran a ~34 W grow light and, separately, a ~380 W dehumidifier until shutdown. Names are as Outdoor Life lists them; only the Yeti 700 and the AC180 are the same models as on our list. The Oupes ran the 380 W test twice (76%, then 92% after three months in storage), and the AC180’s review text gives 39.9% at 34 W where the results table gives 54%. We did not run these tests; we report their numbers.

Arithmetic, not a claim: label Wh × 62% for loads under 100 W (× 87% above) ÷ the load, the middle of Outdoor Life’s measured results above. Appliance wattages are typical; read the plate on yours. “Won’t start” = continuous rating below the running load, or surge rating below the start-up peak.

TakeawayOnly the 1 kWh and 2 kWh classes get a CPAP through the night. The 300 Wh class gives about 4 hours. A full day of refrigerator is beyond the 2 kWh pick, which manages about half a day; the 4 kWh DELTA Pro 3 gets about 24 hours. A space heater runs about an hour on a 2 kWh unit. → Anker SOLIX C1000 Gen 2 · check price

Surge watts: will a power station start a fridge or pump?

A unit’s surge rating covers the start-up peak for a second or two. Continuous W must be at least what you run; surge W at least what it takes to start. Typical values; compressors and pumps vary.

TakeawayCompressors and pumps draw far more than 300 W to start. A fridge needs about 1,000 W, which rules out every 300 W unit here. Our small pick starts one on its 1,200 W surge, then runs it under 2 hours. A ½ hp well pump needs about 2,200 W to start; every 1 kWh and 2 kWh pick here has a published surge of 3,000 W or more. → EcoFlow RIVER 3 Plus · check price

How to choose a portable power station in four questions

What is the biggest thing you need to start?

A fridge, pump or heater rules out the 300 W units (surge chart).

Small loads for hours, or big loads for minutes?

Small loads get about 62% of the label, big ones about 87% (usable Wh).

Will the outage get longer?

Buy a unit that takes add-on batteries (EcoFlow RIVER 3 Plus, EcoFlow DELTA 3 Plus, Jackery Explorer 2000 Plus, EcoFlow DELTA Pro 3 and BLUETTI Apex 300) rather than a second stand-alone box.

Do you need 240 V?

Well pumps, dryers and some HVAC do. The DELTA Pro 3 and the Apex 300 list 240 V from one unit; the Jackery 2000 Plus needs a second unit.

In Germany and looking at balcony solar with storage instead? Different product, different rules (800 W feed-in cap): see our Balkonkraftwerk comparison (in German).

Portable power station FAQ

What size portable power station do I need to run a refrigerator?

For a fridge, look at 1 kWh and up. A full-size refrigerator runs about 150 W but needs about 1,000 W to start, which rules out every 300 W unit here. All six units in the 1 kWh group start one, and those over 1,000 Wh run it about 6 hours; a 2 kWh unit manages about half a day. Filter by Fridge to see the 14 that qualify.

→ Anker SOLIX C1000 Gen 2 · check price

Will a portable power station run a CPAP all night?

Only the 1 kWh and 2 kWh classes, on our arithmetic. For a 40 W CPAP that needs 8 hours, the EcoFlow RIVER 3 Plus (286 Wh) gives about 4.4 hours, about half a night; the Anker SOLIX C1000 Gen 2 (1,024 Wh) about 16 hours; and the Anker SOLIX S2000 (2,010 Wh) about 31 hours. See the runtime chart.

→ Anker SOLIX C1000 Gen 2 · check price

How much usable capacity does a portable power station really have?

Less than the label. Across the twelve units Outdoor Life tested, they got 49–77% of the label at a 34 W load and 78–92% (the Oupes’s first run: 76%) at 380 W. By the middle of those results, a 1,000 Wh label gives about 600 Wh overnight and about 870 Wh at 380 W. The gap is the inverter running itself. See label vs. outlet.

Do I need a 1000W or 2000W portable power station?

Whichever covers what you run at the same time: continuous W must be at least the total you run, and surge W at least what it takes to start. A 1,000 W microwave draws about 1,300 W and a 1,500 W space heater uses all of a 1,500 W unit. Check watts separately from capacity: the 2,010 Wh Anker SOLIX S2000 has 1,500 W continuous, a big battery with a small inverter.

Will a portable power station run a well pump or 240 V appliances?

A ½ hp well pump runs about 800 W but needs about 2,200 W to start; every 1 kWh and 2 kWh pick here has a published surge of 3,000 W or more. Many well pumps, dryers and some HVAC need 240 V: the EcoFlow DELTA Pro 3 and the BLUETTI Apex 300 list that from one unit, and the Jackery Explorer 2000 Plus needs a second unit.

What size portable power station do I need for home backup?

Look at 2 kWh and up. A 2 kWh unit runs a fridge for about half a day and a 40 W CPAP for about 31 hours. For a full day of refrigerator, the 4 kWh EcoFlow DELTA Pro 3 gets about 24 hours. If the outage might get longer, buy a unit that takes add-on batteries.

What we did not do

We did not test, weigh or time any unit: † figures are Outdoor Life’s, the other overnight usable figures are label Wh × 62%, and specs come from maker pages and Amazon listing titles checked September and October 2026, as each card’s source line says. Outdoor Life tested only the Yeti 700 and the AC180 exactly; we left blank any figure we could not find.

Prices, star ratings and rating counts are Amazon’s, from our affiliate network’s catalogue, on the date shown on each card. 6 of the 18 units are not in that catalogue, so their price is blank and their button goes to Amazon or the maker. The three “bought in past month” badges are Amazon’s, recorded Oct 15, 2026. Rating counts are often pooled across a model’s variants.

How we make money on this page. BLUETTI (10%) and ECO-WORTHY (5–10%) pay us a commission when you buy through our tagged links. Anker’s affiliate programme covers our advertising channel but not this site, so the Anker links here are plain and earn nothing; EcoFlow and Goal Zero pay us nothing; Jackery’s programme is pending. None of our three picks is from a brand that pays us on this page.

Researched and written by the Worth To Buy editorial team (Golden Elite, Singapore). We do not test or trial these ourselves. Every figure comes from the maker or provider, from a listing we read on a stated date, or from a third party we name — and the page says which. Rankings are settled before affiliate links are added.
