What will an EcoFlow DELTA 3 Plus run? (US 120 V)

A “1,800 W” power station is two numbers wearing one label. Watts are the ceiling on what you can switch on at once; watt-hours are how much energy is in the battery. The EcoFlow DELTA 3 Plus holds 1,800 W and stores 1,024 Wh on the nameplate — and those two facts answer two different questions.

This page answers the first one. EcoFlow publishes no depth of discharge or inverter efficiency for this model, so there is no defensible usable-capacity figure, and this page will not turn the nameplate into hours.

No usable-capacity figure for this model

The brand publishes a nameplate watt-hour number and nothing about depth of discharge or inverter efficiency. Dividing the nameplate by a load would be wrong by 20–35%, so this page shows the nameplate for what it is and refuses to turn it into hours.

What EcoFlow DELTA 3 Plus runs

Every row is a live calculation against this machine's continuous output, surge ceiling and inverter waveform — running watts, start-up inrush and duty cycle on the appliance side. Of 30 appliance profiles, 15 run, 6 are a tight fit and 9 are out of reach. The percentage is the load as a share of continuous output; anything past 82% drops out of the green.

Solar panels this machine can legally take

The binding constraint is voltage, not watts: open-circuit voltage RISES as it gets colder, and an array that is fine at noon can be over the MPPT ceiling at dawn. Each row is the engine's largest legal array for this station, with Voc corrected to -10 °C ambient . Only panels whose datasheet publishes a voltage temperature coefficient are evaluated — the others cannot be corrected, and an under-corrected array is what destroys an MPPT input.

Every field we hold on this machine

Each figure 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 two manufacturer sources disagree about says that instead of picking one.

AC output

What the inverter can hold, what it can start, and what shape the wave is.

Boost output Manufacturer sources disagree — under review escalated for manual adjudication

The verdict engine never counts boost output as continuous output: it works by dropping voltage and can fail on motors and compressors.

Questions people ask about this machine

Will an EcoFlow DELTA 3 Plus run a full-size refrigerator?
Yes. Against the US 120 V record, the full-size refrigerator draws 55 W running · 286 W at start-up — 3.1% of this machine's continuous output. That verdict is a calculation from running watts, start-up surge and inverter waveform, not a lookup, and the full working is one click away in the table above.
Why can't an EcoFlow DELTA 3 Plus run an electric kettle?
On the US 120 V record the binding constraint is the continuous output. The electric kettle needs 3,000 W running · 3,000 W at start-up, and at 167% of continuous output there is no headroom to give. No accessory fixes this one — it takes a machine with a bigger inverter.
How long will an EcoFlow DELTA 3 Plus run my appliances?
We will not put a number on it, and that is deliberate. A runtime needs a usable-capacity figure, and EcoFlow publishes no depth of discharge or inverter efficiency for this model — only a nameplate watt-hour rating. Dividing that nameplate by your load produces a confident-looking figure that is typically 20–35% too high. What this page gives you instead is every load's energy rate in watt-hours per hour, which needs no battery figure at all and is the number you actually size against.
How long does an EcoFlow DELTA 3 Plus take to charge?
EcoFlow states 56 minutes from empty to full on mains power. That is a manufacturer figure measured under their conditions, verified on 2026-08-01; a cold battery, a weak circuit or a lower charge-rate setting all make it longer.
Can you take an EcoFlow DELTA 3 Plus on a plane?
No. At 1,024 Wh it is far above the 160 Wh ceiling that airlines apply to lithium batteries in the cabin, and lithium batteries of this size are not accepted in checked baggage either. The 100 Wh / 160 Wh thresholds come from the IATA dangerous-goods rules that carriers implement; check your airline before travelling, because the approval step above 100 Wh is theirs to give.
