EcoFlow Smart Generator 4000 (Dual Fuel) — 3200W Output, Industry-Leading Fast DC Charging for DELTA Pro 3
The Smart Generator 4000 is a dual-fuel inverter generator delivering 3200W on gasoline or 2900W on LPG (4000W peak with X-Boost), engineered for industry-leading 3200W DC fast charging when paired with the EcoFlow DELTA Pro 3. Run it on gasoline, LPG, or both for flexible fuel access, and start or stop it five different ways — including fully automatic operation through the EcoFlow app.
⚠ Not CARB-Approved. This product is not CARB-approved and cannot be shipped to or used in California.
⚠ Compatibility. Not compatible with EcoFlow DELTA Pro Ultra or RIVER Series for DC charging and automatic start-stop functionality. AC charging works with any compatible power station via the AC output port.
⚠ Single Fuel Source at a Time. LPG and gasoline cannot be used simultaneously — they are mutually exclusive. The engine switch must be manually set to the correct fuel source before starting.
