Every check passes. What this page will not do is turn a nameplate watt-hour rating into hours — see the evidence below for why.

Two numbers decide this, and readers use them interchangeably: watts are the ceiling on what the inverter holds at any instant, watt-hours are how much energy the battery holds. A machine can have plenty of one and not enough of the other.
The verdict is a calculation, not a lookup. What it will not do is print a runtime, and the reason is specific: we have found no published depth of discharge or inverter efficiency for the EU 230 V build, so there is no usable-capacity figure to divide.
Where those numbers come from
A blank is never left blank. A field we have found no figure for says so, and a field whose
sources disagree — two documents, or one document with itself — says that instead of picking
one.
No usable-capacity figure for this machine
EcoFlow states a nameplate watt-hour number for it, and we have found no published depth of discharge or inverter efficiency for the EU 230 V build. Dividing the nameplate by this load would be wrong by 20–35% in the flattering direction, so this page shows the nameplate for what it is and refuses to turn it into hours.

Energy rate instead of a runtime
47 Wh per houraveraged over this load’s duty cycle
This number needs no battery figure at all, which is why this page can give it when it cannot give hours. Divide any usable-capacity figure you trust by it and you have your own runtime, with our arithmetic visible instead of hidden.

That works out to 286 W, which is the figure checked against this machine's surge ceiling.

Start-up figureCategory envelope — not a manufacturer figure
We have found no published inrush figure for this class. The multiple this site uses is therefore a category envelope drawn from standards tables: deliberately conservative, and not a measurement of any particular unit. A verdict held back by it may well be fine in practice — we will not say so until a manufacturer does.

BLUETTI Elite 30 V2 (EU 230 V) reaches the same conclusion on a full-size refrigerator at 600 W continuous, and it is €219. Cheaper is only cheaper when the answer is the same — this one is. See that pairing →

From the Knowledge channel
A full-size refrigerator has a dedicated guide: 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 pairing
Will an EcoFlow DELTA 2 Max run a full-size refrigerator?
Yes. 55 W of running draw against 2,400 W of continuous output — 2.3% of it, with 286 W demanded at start-up against a 4,800 W ceiling. The verdict is computed from running watts, start-up inrush, and inverter waveform — the working is in the evidence section above.
How long will an EcoFlow DELTA 2 Max run a full-size refrigerator?
We will not put a number on it, and that is a finding rather than a gap. We have found no published depth of discharge and no inverter efficiency for the EU 230 V build. What it does state is a nameplate watt-hour rating. Dividing that nameplate by this load produces a figure that is typically 20–35% too high while looking exactly as authoritative as a real one. What this page gives instead is the load's energy rate in watt-hours per hour, which needs no battery figure at all.
Why is there no runtime on a page that says yes?
Because "yes it runs it" and "yes for this long" are two different claims with two different evidence requirements, and this machine only supports the first. The verdict needs a continuous rating and a surge ceiling, which EcoFlow publishes. Hours need a usable-capacity figure, which it does not. Twenty of the twenty-six machines in our library are in that position, and the alternative — nameplate watt-hours divided by label watts — is the single most common wrong number on this topic.
