Will an EcoFlow STREAM Ultra run a full-size refrigerator? (EU)
Yes, it runs it — no usable-capacity figure see why below ↓
Every check passes: 55 W running against 1,200 W continuous, and 286 W at start-up inside a 1,200 W ceiling. 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 arrive using them interchangeably. Watts are the ceiling on what the inverter can hold at any instant — a full-size refrigerator needs 55 W of them while it runs, and 286 W for the instant it starts. Watt-hours are how much energy the battery holds, and the EcoFlow STREAM Ultra holds 1,920 Wh of them on the nameplate. A machine can have plenty of one and not enough of the other.
The verdict above is a calculation — running watts, start-up inrush and inverter waveform against this machine's continuous output and surge ceiling — not a lookup. What it will not do is print a runtime, and the reason is specific: EcoFlow publishes no depth of discharge or inverter efficiency for this model, so there is no usable-capacity figure to divide.
Where those numbers come from
Every figure below carries the tier it came from and the date it was checked. A blank is never left blank: a field the manufacturer does not publish 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 publishes a nameplate watt-hour number and nothing about depth of discharge or inverter efficiency for this model. 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.

The surge ceiling on this page is ours, not the manufacturer’s
EcoFlow does not publish a surge rating for this model. So the start-up check runs against the continuous output instead — an inverter cannot surge below what it sustains, which makes that the safest number we can defend. Real inverters usually manage 1.5–2× their continuous rating, so a start-up call held back by this figure may well be fine in practice; we are not going to say so until the manufacturer does.
Energy rate instead of a runtime
47 Wh per hour averaged over this load’s duty cycleThis 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.
What a full-size refrigerator demands
That works out to 286 W, which is the figure checked against this machine's surge ceiling.
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.
What the EcoFlow STREAM Ultra offers
This figure is ours, not the brand’s: the continuous rating used as a conservative floor because no surge rating is published for this model.

If this is not the pairing
Anker SOLIX C300 (EU 230 V) reaches the same conclusion on a full-size refrigerator at 300 W continuous, and it is €269.99. Cheaper is only cheaper when the answer is the same — this one is. See that pairing →
