RefrigerationAlso called: refrigerator, fridge, full size refrigerator
Two numbers decide whether a power station runs a full-size refrigerator, and readers arrive using them interchangeably. Watts are the ceiling on what the inverter can hold at any instant — this load needs 55 W of them while it runs, and 286 W for the moment it starts. Watt-hours are how much energy the battery holds, and this load gets through about 1,123 Wh in a day. A machine can have plenty of one and not enough of the other.
Of the 26 machines in our library, 26 run it, 0 are a tight fit and 0 are out of reach. Each of those is a calculation against that machine’s continuous output, its surge ceiling and its inverter waveform — not a lookup table — and the reasoning is on every row.

Start-up figure: Category envelope — not a manufacturer figure
No manufacturer we checked publishes an inrush figure for this class, so the multiple this site uses is a category envelope drawn from standards tables. It is deliberately conservative, it is not a measurement of any particular unit, and its confidence is capped accordingly. A verdict held back by this number may well be fine in practice — we will not say so until a manufacturer does.

Two ways to read a duty cycle
A duty cycle can be read two ways and they are not the same number. One is the constant a test procedure assumes so that a label figure is reproducible; the other is what the machine does in a real room, which depends on the weather, the door and the thermostat. This record keeps both ends: 50% to 100%, with the default above. The named readings below each carry their own source and date, so you can see which one a figure came from rather than being handed a blend of the two.

What actually decides it
A motor load: the first half-second decides it
An induction motor with a stationary rotor is close to a short circuit. For the fraction of a second before it turns, it pulls several times its running current, and that peak — not the running figure — is what trips an inverter. This is why a machine drawing well under a station’s continuous rating can still fail to start on it, and why the start-up figure at the top of this page matters more than the running one.
What kind of motor is inside
It is a reciprocating (piston) compressor, which has to start against whatever refrigerant pressure is left in the system. That is why the restart right after a power cut is harder than a start from cold, and why a station that ran it all night can still stumble on the next cycle.
How long the start-up actually lasts
The inrush lasts a couple of tenths of a second, which is the window a station’s surge rating is written for. This is the one case where the surge figure and the surge ceiling are directly comparable.
Which power stations run it
Every row is a live calculation against that machine's continuous output, surge ceiling and
inverter waveform. Of 26 machines, 26 run it, 0 are a tight fit and 0 are out of reach. The percentage is
this load as a share of that machine's continuous output; anything past 82% drops out of the green. Rows are ordered by verdict, then by
price — cheapest first inside each band.

Between the anchorsOnly the anchor points above have a source. This site does not interpolate between them: a curve drawn through two published points is a number we invented, and it would arrive on the page wearing the same official label as the points it was drawn from.
Mains standards on recordUS 120 V · EU 230 VThe figures above are recorded per mains standard, because the same appliance class is built differently on 120 V and 230 V. Where only one standard is on record, the ranking still lists machines from both regions — each row states its own.
Everything else we hold on this load

A full-size refrigerator has a guide of its own: the same records this page computes from, worked through in prose with room for the reasoning a table can only summarise — How many watts does a refrigerator actually use in a day?
Questions people ask about this load
How many watts does a full-size refrigerator use?
55 W while it is running, and 55–88 W across the models in this class, with 286 W demanded at the instant it starts. Those are different questions and most pages answer only the first. The running figure decides whether a machine can hold it; the start-up figure decides whether it can get it going at all, and it is usually the one that fails. No manufacturer we checked publishes an inrush figure for this class, so the multiple this site uses is a category envelope drawn from standards tables.
What size power station do I need for a full-size refrigerator?
For a full-size refrigerator, the EcoFlow RIVER 3 Plus (US 120 V) is the cheapest machine in our library that runs it, at 600 W continuous · 1,200 W surge ceiling and $259 against a running draw of 55 W and a start-up demand of 286 W. That is a verdict computed from this load’s running watts, its start-up demand and the inverter waveform — not a rule of thumb about doubling the wattage. 26 of 26 machines clear it, 0 are a tight fit, and the tight ones are tight for reasons the list states individually.
How long will a power station run a full-size refrigerator?
It depends entirely on the machine, which is the part most pages skip. Against 55 W of running draw, our figures put the BLUETTI Elite 30 V2 at about 4.4 h, and the BLUETTI Elite 100 V2 at about 15 h. Those hours come from usable-capacity figures derived from the manufacturers’ own published depth of discharge and inverter efficiency, with each machine’s idle draw in the denominator — not from dividing a nameplate watt-hour number by a label wattage. Most machines in the list carry no hours at all: their brands publish nothing that makes a usable-capacity figure defensible, so those rows give an energy rate instead of a number we would have had to invent.
Why does a full-size refrigerator need so much more power to start?
No manufacturer we checked publishes an inrush figure for this class, so the multiple this site uses is a category envelope drawn from standards tables. It is deliberately conservative, it is not a measurement of any particular unit, and its confidence is capped accordingly. A verdict held back by this number may well be fine in practice — we will not say so until a manufacturer does. The engine works the check against 286 W, which is what a station's surge ceiling has to cover for the moment the machine starts. A station whose continuous rating is comfortably above the running figure can still refuse the start, and that is the single most common way a purchase goes wrong for this class.
Does a full-size refrigerator draw that continuously?
No, and the difference is most of the energy question. This record holds more than one duty-cycle reading, each with its own source: Normal room, 22°C at 85%, Hot & humid, approaching continuous at 100%. The one a page picks silently is the one that decides whether your battery lasts the night, so this site names them and lets you choose in the calculator rather than blending them into a single average.
