EcoFlow Smart Generator (Dual Fuel)
Gasoline or LPG, up to 20 kWh of runtime and automatic start: the smart generator that recharges your EcoFlow station on its own when solar is not enough.
Characteristics
- Fuel: Gasoline or LPG (dual fuel)
- Runtime: 5.4 kWh gasoline / up to 20 kWh LPG
- Power: Up to 1800 W (1600 W on LPG)
- Smart: Auto start, app, -40% fuel
- Auto-recharges the DELTA, gas or LPG
Detailed overview: EcoFlow Smart Generator gasoline and LPG
The EcoFlow Smart Generator (Dual Fuel) is an inverter-technology generator designed to work hand in hand with the DELTA series portable power stations. Its distinctiveness is twofold: it accepts two fuels, gasoline and LPG (liquefied petroleum gas), and it integrates intelligently with your backup power system.
On gasoline, its 4-litre tank produces around 5.4 kWh, ideal for quick backup. On LPG, it climbs up to 20 kWh of energy with a standard bottle, meaning up to 12.5 hours of operation, for cleaner combustion and easy storage. It delivers up to 1800 W (1600 W in LPG mode), a power calibrated above all to recharge a DELTA station while simultaneously powering a few appliances.
Its intelligence makes the difference: paired with a DELTA station and EcoFlow Power Kits, it starts and stops automatically based on battery level, saving up to 40% fuel compared with continuous operation. It is controlled and monitored in real time via the app, offers four starting modes and includes five safety alerts as well as a carbon monoxide detector. Designed for easy maintenance, it stays contained at 56 dB measured at 7 metres.
A self-sufficient backup solution, this dual-fuel generator is for anyone who wants to extend an EcoFlow station's autonomy indefinitely, on long camping trips, off-grid, or as a home safety net when solar is not enough.
Comparison
At around 900 to 1100€, the EcoFlow Smart Generator (Dual Fuel) compares with portable inverter generators, targeted by searches such as "inverter generator" or "dual fuel generator". Its difference lies in its integration with EcoFlow stations. Here is how it sits against three classic references.
| Criterion | EcoFlow Dual Fuel | Honda EU22i | Champion 2500 Dual Fuel | Gasoline inverter unit |
|---|---|---|---|---|
| Fuel | Gasoline + LPG | Gasoline | Gasoline + LPG | Gasoline |
| Power | 1800W | 2200W | 2500W | 2000W |
| Auto start (station) | Yes (paired DELTA) | No | No | No |
| App control | Yes | No | No | No |
| Observed price | ≈ 999 € | ≈ 1300 € | ≈ 700 € | ≈ 500 € |
In short, the EcoFlow generator is neither the most powerful nor the cheapest, but it is the only one to integrate natively with a power station: automatic start and stop based on battery, app control, and dual fuel for flexibility. A Honda EU22i remains a benchmark of reliability and raw power, a Champion Dual Fuel is more affordable, but none offers the smart automation that makes the EcoFlow solution so appealing for extending a DELTA's autonomy.

Our tester's review: Christophe Delpuech
We paired this dual-fuel generator with a DELTA station to test the scenario that really matters for it: long-duration autonomy when solar is no longer enough. That is where it makes full sense. Connected to the station, it starts on its own when the battery drops below a threshold, recharges, then stops, without you having to monitor anything, a life-changing convenience on extended camping trips or during multi-day outages. The dual fuel is a real plus: gasoline for quick backup, LPG for long duration (up to 20 kWh and around a dozen hours), with cleaner combustion and easy bottle storage as a bonus. App control lets you track the level and start recharging remotely, and the CO detector is reassuring. On noise, 56 dB at seven metres is reasonable for a generator, without being silent. Two caveats: the 1800 W power destines it to recharge a station rather than directly power large appliances, and you have to accept the fuel logistics. But as a smart complement to an EcoFlow station, it does exactly what you expect of it.
