Two numbers decide whether a power station runs a 12V portable fridge/freezer, and readers arrive using them interchangeably. Watts are the ceiling on what the inverter can hold at any instant — this load needs 90 W of them while it runs, and 180 W for the moment it starts. Watt-hours are how much energy the battery holds, and this load gets through about 222 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.

The band is the spread across real models in this class, not a tolerance. Size against the top of it unless you know which unit you own.
Start-up figure: Manufacturer-stated
The start-up figure is published by the manufacturer for this device, so it describes the actual hardware rather than a category.
This record publishes both an absolute inrush and a multiple of running power. They do not agree exactly, so the engine checks against the more demanding of the two — 180 W — rather than picking the flattering one.

What actually decides it
A variable-speed motor: it ramps instead of slamming
This compressor is fed by its own electronics, which start it gently and then modulate its speed to the work in front of it. The start-up peak is small or absent, and the running draw is a band rather than a point — low most of the time, climbing only under load. The binding constraint is usually the top of that band, not the start.
What kind of motor is inside
The motor is brushless and driven by its own inverter board, which is why the start-up demand is modest: the electronics ramp the motor rather than connecting it straight to the line.
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.

How many watts does a 12V portable fridge/freezer use?
90 W while it is running, and 78–125 W across the models in this class, with 180 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. The start-up figure here is the manufacturer’s own..
What size power station do I need for a 12V portable fridge/freezer?
For a 12V portable fridge/freezer, 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 90 W and a start-up demand of 180 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 12V portable fridge/freezer?
It depends entirely on the machine, which is the part most pages skip. Against 90 W of running draw, our figures put the BLUETTI Elite 30 V2 at about 1.8–2.8 h, and the BLUETTI Elite 100 V2 at about 6.1–9.4 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 12V portable fridge/freezer need so much more power to start?
The start-up figure is published by the manufacturer for this device, so it describes the actual hardware rather than a category. The engine works the check against 180 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.
Which power stations run a 12V portable fridge/freezer?
26 of the 26 we hold, listed above cheapest-first within each verdict band, starting with the EcoFlow RIVER 3 Plus. 0 more are a tight fit on a 12V portable fridge/freezer — they run it, but with less headroom than we are willing to call comfortable — and 0 cannot. Every one of those is a live calculation against that machine's own record, and opening a row shows the working.
