The power just went out. What needs to stay on?

Switch on what matters. We’ll show how long each battery power station keeps it running — and roughly what time it gives out — using sourced specs and math you can check.

Switch on what you need

Add something else (freezer, sump pump, medical device…)

Use the watts on its label or power adapter — or, for a fridge or freezer, the yearly kWh on its yellow EnergyGuide label.

Fine-tune the numbers

Run small devices (router, phones, laptop, CPAP) from the station’s DC/USB ports

Only if you have the right DC adapter or cable for each. Everything else stays on the AC outlets.

Every station we cover

Nine stations from five brands, specs checked against manufacturer pages and manuals on October 12, 2026. No prices or star ratings — we haven’t tested these ourselves, and prices change daily.

Answers to the questions people actually ask

How long will a power station run a fridge?

About 12 hours for a typical full-size fridge on a 1,000Wh station — and how to get the real number from your fridge’s energy label.

Power station for a CPAP

Why the humidifier matters more than the station, why DC beats AC at night, and how to test before you rely on it.

Apartment and renter backup

What a plug-in battery can and can’t do when a generator isn’t an option.

The 1,000Wh class compared

DELTA 2, AC180, SOLIX C1000, Explorer 1000 v2 and R1500 — which fits which outage.

Why trust these numbers

Every spec is sourced and dated. Each station page links the manufacturer page or manual we used and says where sources disagree. Where they conflict, we use the more cautious figure.

The math is public. One calculation drives the battery size, the verdicts and the runtimes, so they can’t contradict each other. See every formula and assumption.

We say what we haven’t done. We haven’t lab-tested these stations. Our efficiency estimate is based on published independent tests, and the range under each result shows the uncertainty.

Verdicts ignore money. Rankings come from your load and the specs. We have no affiliate links today, and adding them later won’t change a verdict.
