Product Details

The EcoFlow Smart Generator 4000 delivers 3200W of dual-fuel (gasoline/LPG) power with native integration into EcoFlow's DELTA Pro, DELTA Pro Ultra, and compatible power station ecosystems. Unlike conventional generators that run continuously, this unit communicates directly with connected EcoFlow stations via the Smart Generator Adapter — auto-starting when battery reserves drop below a set threshold and auto-stopping when the station reaches the target charge level.

This intelligent activation pattern cuts fuel consumption and noise exposure dramatically compared to continuous operation. In practice, the generator runs in short bursts during high-demand periods or extended cloudy stretches, while the power station provides silent, clean energy the rest of the time.
