Your Unshakeable Power Foundation

When the lights go out or when you're far from the grid, true peace of mind comes from a power source you can trust. The EcoFlow Smart Generator 4000 Dual Fuel is engineered to be that cornerstone of reliability. It's more than a generator; it's an intelligent power hub designed to integrate flawlessly with your EcoFlow DELTA power station, creating a robust backup system that thinks for itself. Choose the ultimate in energy resilience and smart power management.

Redefining Reliability with Dual Fuel Flexibility

Why limit yourself to one fuel source? The core innovation of EcoFlow Smart Generator 4000 Dual Fuel is its ability to run seamlessly on both clean-burning LPG (propane) and traditional gasoline. This dual-fuel capability is a game-changer for preparedness and convenience.

• LPG for Clean, Stable Power: Propane burns cleaner than gasoline, producing significantly fewer emissions and leaving less carbon residue in your engine. It also has an indefinite shelf life, making it the perfect fuel for long-term storage and emergency readiness.

• Gasoline for Universal Availability: When LPG isn't handy, switch to gasoline. This ensures you have power no matter where you are, leveraging the most widely available fuel.
  This flexibility means you're always prepared. You can prioritize clean operation at home with LPG during an outage and switch to gasoline for convenience on a remote job site. The EcoFlow Smart Generator 4000 Dual Fuel gives you the strategic advantage of choice.

Intelligent Integration: Smarter Than a Standard Generator

This isn't a noisy, manual machine from the past. It's a smart component of your modern energy ecosystem.

• Auto Start/Stop: When EcoFlow Smart Generator 4000 Dual Fuel paired with a compatible EcoFlow DELTA power station, the generator automatically kicks on when your battery level drops and shuts off once it's fully recharged. This maximizes fuel efficiency, minimizes runtime, and lets you sleep through the night without interruption.

• Optimized 3200W DC Charging: Unlike standard AC generators that lose efficiency converting power, this unit delivers 3200W of direct DC current to your power station. This results in dramatically faster charging times—up to 70% faster than conventional methods—getting your home backup system from zero to full in a fraction of the time.

• Remote Monitoring & Control: Manage everything from the EcoFlow mobile app. Check fuel status, start or stop the unit, and monitor performance from the safety and comfort of your home.

With a sufficient fuel supply and proper ventilation, it is designed for extended operation. Always refer to the official user manual for specific runtime figures and maintenance schedules under continuous load.

Do I need a special propane tank?
It connects to a standard 20 lb (or larger) propane tank using the included regulator and hose, the same type commonly used for backyard grills.

Can I use it while it's raining or snowing?
The unit must be protected from direct exposure to precipitation. Always operate it under a well-ventilated, covered structure like a generator tent or canopy to ensure safety and prevent damage.

What makes it "smarter" than other dual fuel generators?
Its exclusive integration with the EcoFlow ecosystem allows for automatic, fuel-saving operation with your power station and remote app control, features not found on conventional generators.

Is the EcoFlow Smart Generator 4000 Dual Fuel eligible for shipment to my state?
