Will an EcoFlow RIVER 3 Plus run a portable split air conditioner? (EU 230 V)
Exceeds output — nothing to time — it will not run see why below ↓
The load is more than this inverter can sustain. 1,500 W against 600 W continuous — 250% of it. No accessory closes a gap that size — it takes a bigger inverter.

Two numbers decide this, and readers arrive using them interchangeably. Watts are the ceiling on what the inverter can hold at any instant — a portable split air conditioner needs 1,500 W of them while it runs. Watt-hours are how much energy the battery holds, and the EcoFlow RIVER 3 Plus holds 286 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: there is nothing to time. A runtime for a load this machine will not start is a figure about nothing.
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.

Energy rate instead of a runtime
1,500 Wh per hour while it is actually runningThis is the draw while the machine is running and it is deliberately NOT averaged over a duty cycle: for this load the two figures are not commensurable, so their product is not a real quantity. This number multiplies nothing, which is why it survives.
What a portable split air conditioner demands
The inverter is loaded to 1,613 VA — 1,500 W ÷ 0.93 — which is the quantity its ceiling is actually measured against. Those are not the watts in the row above: this load modulates, so the verdict is taken at the top of the range its record publishes rather than at the rated point.
What the EcoFlow RIVER 3 Plus offers
What this page is not going to sell you
There is no buy button on this page, and that is the finding rather than an omission: the EcoFlow RIVER 3 Plus does not run a portable split air conditioner. A price here would be a sale, not an answer.
