Product Description

The DELTA 3 Max is EcoFlow's current mid-size power station and the replacement for the DELTA 2 Max: 2,048 Wh of LFP battery behind a 2,400 W inverter, in a case you can still lift into a truck bed on your own. It is the size most people land on when the goal is a refrigerator through a power cut, a satellite terminal that stays online, or a camp that runs for several days without a generator.

What it will actually run

Watt-hours only mean something once you turn them into hours. Working from 2,048 Wh and allowing for inverter losses, the DELTA 3 Max gives roughly a day and a half on a domestic refrigerator, about two days of continuous Starlink Mini, close to twenty hours on a Starlink Standard kit, and several days of lights, laptops, phone charging and a satellite phone or messenger. A CPAP runs for two or three nights. Those are estimates for planning, not guarantees — your own appliances decide the real number.

The 2,400 W inverter is the other half of the story. It starts a domestic fridge, runs a microwave or a coffee maker, and handles power tools on a job site. X-Boost pushes that to 3,400 W for heating loads such as a kettle or a space heater, though it is not suitable for precision equipment.

Who buys this one

Homeowners who want the essentials covered through an outage without a permanently installed system. Overlanders and RV owners running a 12 V fridge and charging everything at camp. Anyone relying on satellite communication in the field, where a dead battery is not an inconvenience but a safety problem. If you need multiple days rather than one, look at the expandable DELTA Pro class instead; if you mostly need to keep comms and laptops alive, a smaller RIVER-class station will do it for less weight.

Common questions

A Starlink Mini draws roughly 25–40 W, so 2,048 Wh works out to about two days of continuous use after inverter losses. Running it from the 100 W USB-C port rather than an AC outlet avoids the inverter entirely and stretches that further. Add a folding solar panel and you can stay online indefinitely in decent sun.

Yes. A full-size fridge uses about 1–2 kWh a day, so a DELTA 3 Max covers roughly a day to a day and a half on its own. The 2,400 W inverter starts a domestic fridge comfortably, and you can run the router, lights and phone charging alongside it.

No. Airlines cap lithium batteries at 100 Wh in carry-on, with 101–160 Wh allowed only by prior approval. At 2,048 Wh the DELTA 3 Max is far above that limit and cannot fly as passenger baggage. For air travel you want a power bank of 100 Wh or less.

Three: a standard wall outlet (100–120 V, 15 A), solar at up to 500 W through the 11–60 V input, and a vehicle at 12 V, 24 V or 48 V. You can set a slower, gentler charge speed in the EcoFlow app when the unit is plugged in overnight.

If they fall inside the 11–60 V and 13 A window, yes — that covers EcoFlow's 110 W, 160 W, 220 W and 400 W folding panels and most third-party panels with MC4 connectors. Check open-circuit voltage before connecting; too high a voltage is the one mistake that damages a power station.

No — it replaces it. Both hold 2,048 Wh and both put out 2,400 W of AC, but the DELTA 3 Max is the newer generation: about five pounds lighter, rated for more charge cycles, and built on EcoFlow's current app and charging platform with a 100 W USB-C port. If you are choosing today, the DELTA 3 Max is the current model.

Yes you can buy satellite phones, we offer the best satellite communication options. Including Iridium, Globalstar, and Inmarsat. Satmodo offers satellite phones that work anywhere in the world.
Do I need to rent or purchase a satellite phone?
