Runtimes are a range because the device's draw varies. The lower figure assumes it draws at the top of its range for the whole time, the higher assumes the bottom. This device cycles on and off, so the figures assume it runs about 35 per cent of the time. How we calculate runtime.

10 models cannot run this device at all

Capacity is not the constraint. These have the stored energy but their inverters cannot deliver the startup surge, so they fail the moment the device kicks in.

• Goal Zero Yeti 700 (677Wh): 1000W surge cannot start a device needing 1200W
• Jackery Explorer 500 (518Wh): 1000W surge cannot start a device needing 1200W
• Jackery Explorer 500 v2 (512Wh): 1000W surge cannot start a device needing 1200W
• Goal Zero Yeti 300 (297Wh): 600W surge cannot start a device needing 1200W
• Jackery Explorer 300 Plus (288Wh): 600W surge cannot start a device needing 1200W
• Anker SOLIX C300 (288Wh): 600W surge cannot start a device needing 1200W
• Jackery Explorer 240D (256Wh): No AC inverter: this unit has DC outputs only and cannot run a mains appliance
• EcoFlow RIVER 2 (256Wh): 600W surge cannot start a device needing 1200W
• EcoFlow RIVER 3 (245Wh): 600W surge cannot start a device needing 1200W
• Bluetti AC2A (204Wh): 600W surge cannot start a device needing 1200W

Yes, a portable power station can run a refrigerator. The part people get wrong is what actually stops it working: not the battery size, but the inverter’s surge rating. A compressor draws several times its running watts for a fraction of a second at startup, and a power station that cannot clear that spike shuts off before the fridge ever gets going.

A full-size fridge needs roughly 1,200W of surge headroom to start, then settles to 150 to 250W while the compressor runs, which is only about a third of the time. The table above shows which current models clear each scenario and what they cost.

What a fridge actually draws

The number on the fridge’s label is the compressor running, not what it draws on average. A fridge rated at 250W is not pulling 250W continuously: the compressor cycles on to cool the cabinet, then shuts off once it reaches temperature, and only runs about a third of the time overall.

That duty cycle is why a fridge that looks like a heavy load on paper is a manageable one in practice. A unit labelled 250W running at a one-third duty cycle averages closer to 70W over an hour, which is a fraction of what the label implies. Runtime estimates need to use that average, not the label figure, or they undersize the outage window a fully charged station can actually cover. For a worked example at a specific battery size, see how long a 1000Wh power station runs a fridge.

For the full explanation of why the label overstates the load, see Your Fridge Uses Less Power Than You Think. For what that startup spike is and why it matters more than the running watts, see What Is Startup Surge?

A small fridge is a different problem

Everything above assumes a full-size fridge. A compact or under-counter fridge, the kind in a dorm room, office or garage, is a materially easier load and the shortlist above is sized more conservatively than it needs.

	Full-size	Small fridge
Surge to start	About 1,200W	About 800W
Running draw	150 to 250W	100 to 150W
Models that cannot start it	10 of the 42 we track	7 of the 42 we track

The lower surge threshold is what matters. Three models that cannot start a full-size fridge can start a small one: the Goal Zero Yeti 700, and both the Jackery Explorer 500 and 500 v2. All three carry a 1,000W surge rating, which clears 800W but not 1,200W. If you are buying for a compact fridge specifically, they are back on the table.

The seven that still fail are the 600W-surge units and the DC-only Jackery Explorer 240D, named in the exclusions list above. A small fridge is easier, not trivial.

Size a small fridge in the calculator rather than reading the full-size figures across.

Why some power stations fail

Two different specs decide whether a power station can run a fridge, and they are not related. Surge rating is the peak the inverter can deliver for an instant. Capacity is the total energy stored in the battery. A unit can have a huge battery and still fail the moment the compressor kicks in, because its inverter was never built to clear a four-figure surge.

This is why a bigger battery is not automatically a safer buy for fridge backup. Some models pair a large cell with a modest inverter, aimed at running lights and electronics rather than motors. Against a fridge, that combination trips on the first startup cycle rather than running out of charge hours later.

The exclusions list under the table above names every current model that fails this way and explains which spec falls short.

Two days is not realistic on one charge

Running a fridge for a full 48 hours on a single charge is not realistic for the catalogue we track today, and the table above reflects that honestly rather than stretching a number to fit. Multi-day coverage needs a different approach than buying a bigger single unit.

An expansion battery pack, where the manufacturer supports one, adds capacity without needing a second inverter, which is the more efficient way to stretch runtime once the base unit already clears the surge. A small solar panel can claw back charge during daylight hours, which matters more for a multi-day outage than it does for an overnight one, because there is time for the sun to do useful work between cycles.

The simplest option costs nothing: leave the door shut. An unopened fridge holds a safe temperature for around four hours without power, and a full freezer holds it for closer to 48. That makes the practical goal bridging the gap between charges, or running the fridge intermittently, rather than powering it continuously for two full days. Pre-cooling the fridge to its coldest setting before an expected outage extends that window further, since it starts the clock with more thermal mass to work through.

For a different fridge size or a mix of devices, use the calculator directly.

Bottom line

Check the surge rating before the battery size: capacity only matters once the inverter has already proven it can start the compressor. Expect a fridge-capable power station to comfortably cover an overnight outage, plausibly stretch to a full day, and struggle to reach two days without an expansion battery, solar, or keeping the door shut.
