The EcoFlow Smart Generator 4000 (Dual Fuel) is a powerful, high-efficiency inverter generator built for dependable home backup, RV power, off-grid cabins, and extended outages. With 3200W of rated AC output on gasoline, 2900W on LPG, and 4000W peak with X-Boost, it delivers strong, stable power for essential appliances and high-demand devices.

Fueled by a robust 196cc four-stroke engine, the Smart Generator 4000 supports both unleaded gasoline and propane, giving you flexible fueling options for short-term or long-duration emergencies. Its 6 L fuel tank provides up to 2.8 hours at full load and 8 hours at 1/4 load (gasoline), making it reliable for overnight or multi-day backup scenarios.

As a true inverter generator, it provides clean, consistent power suitable for sensitive electronics like laptops, routers, Starlink, medical devices, and communication equipment. It also features a 40–60 V DC output (up to 56 A) for ultra-efficient charging of compatible EcoFlow power stations, reducing fuel consumption and runtime compared to AC-only generators.

A key advantage of the Smart Generator 4000 is its seamless integration with most EcoFlow DELTA power stations, allowing automatic start and stop when battery levels fall or recharge completes. This hands-free functionality provides fully automated backup power during storms, outages, or extended off-grid use—something the Smart Generator 3000 does not offer.

Despite its high output, the generator remains practical and portable. Weighing 38 kg (83 lb) with dimensions of 633 × 381 × 529 mm, it stores easily in RV compartments, garages, and sheds. Noise levels of 70 dB at 7 m (full load) keep operation quieter than many conventional generators in its class.

Smart features like four self-starting modes, an easy-to-read HD LCD screen, multiple safety alerts, and full EcoFlow App control make the Smart Generator 4000 a modern, efficient, and reliable solution for home backup and off-grid power.

Perfect for home emergency energy, RV travel, off-grid cabins, and users who need fast, efficient, dual-fuel power with advanced automation.
