Product Overview

The EcoFlow Smart Generator 4000 Dual Fuel is a powerful and intelligent backup energy solution engineered for users who need dependable power with flexible fueling options. Designed to operate on both LPG and gasoline, this generator adapts easily to different environments, fuel availability, and usage scenarios. With a strong 3200W DC output, it is optimized to recharge EcoFlow portable power stations quickly while also delivering reliable standalone power when needed.

Built to integrate seamlessly into the EcoFlow ecosystem, this generator automatically communicates with compatible EcoFlow DELTA power stations, turning on and off based on battery levels. This intelligent operation improves fuel efficiency, reduces noise, and minimizes manual intervention. The EcoFlow Smart Generator 4000 Dual Fuel is ideal for home backup, RV travel, remote job sites, and emergency preparedness.

Dual Fuel Flexibility for Real World Reliability

One of the most valuable advantages of the EcoFlow Smart Generator 4000 Dual Fuel is its ability to run on either LPG or gasoline. LPG offers cleaner combustion, longer storage life, and reduced emissions, making it an excellent option for extended backup use. Gasoline provides widespread availability and convenience, ensuring power access even when LPG is unavailable.

This dual fuel design allows users to choose the most practical option at any moment without compromising performance. Whether preparing for long term outages or powering equipment in remote areas, the generator delivers consistent output and stable charging performance.

Optimized for EcoFlow Power Stations

The EcoFlow Smart Generator 4000 Dual Fuel is specifically designed to work in harmony with EcoFlow DELTA series power stations. Through direct DC charging, it recharges batteries faster and more efficiently than traditional AC generators. Smart automation enables the generator to start automatically when battery levels drop and shut off once charging is complete.

This intelligent energy management system extends fuel runtime, reduces unnecessary operation, and helps maintain a quieter environment. Users benefit from hands free operation, especially during overnight use or extended outages.
