• | Two Fuel Sources: With either LPG or gas, you've got two energy sources to deliver higher efficiency, easier use, and fewer emissions. |
• | Newest Part of the EcoFlow Ecosystem: Set it to charge your Ecoflow products automatically when they drop to a certain level. All while having higher charging efficiency. |
• | Smart Control & Monitoring : Use the EcoFlow app to control and monitor from afar. |
• | Seamless LPG Set Up: Plug in propane easier than ever with a switch & built-in regulator for ultimate convenience. |

• | EcoFlow Smart Generator (Dual Fuel) 4000 not only offers significant fuel savings but also generates fewer emissions. Compared to traditional fuel generators, it can save 40% of fuel when fully charging the EcoFlow DELTA Pro 3. This means that with the same 1 gallon of fuel, this smart generator provides 1kWh more power. |

• | With four intelligent self-starting backup modes (when paired with EcoFlow DELTA Pro 3), power backup has never been easier. |
• | At night, once the power consumption reaches a certain level, the smart generator will automatically start to replenish power, eliminating the need to get up in the middle of the night to reset it. |
• | Monitor the remaining power of the EcoFlow DELTA Pro 3 energy storage in real-time, predict future power consumption and measure the power generation from PV, and auto-recharge it in time to ensure a peaceful night's sleep and rest for your family and neighbors, avoiding noise during charging at night or during peak power consumption periods. |
• | Recharge the EcoFlow DELTA Pro 3 with PV panels, automatically prioritizing PV charging for savings and environmental benefits while minimizing noise from continuous generator operation. Need more power quickly as an outage approaches? One tap in the EcoFlow app switches back to PV and Smart Generator charging combo for swift reinforcement. |
• | It provides a reverse power supply to the generator battery through EcoFlow DELTA Pro 3 to wake up the generator and start charging it at the same time. Also, to prevent the Smart Generator battery failure caused by long-term storage or extremely low temperatures, it protects household electricity during severe weather scenarios. |
• | Rest easy knowing that LPG and gasoline are readily accessible, ensuring you can quickly obtain fuel for backup power and alleviating concerns about fuel shortages during emergencies. |
• | The smart engine produces 8kWh in single gasoline tank, you could power your home appliances for 8-hours at 25% load. |
• | Simply plug in a 20lb propone tank and allow you access to a 24kWh power, secured and keep your family a whole day of cozy life in a outage. |

• | Use the EcoFlow app to monitor and control energy consumption and equipment operation. Get real-time key alerts like CO concentration, high & low temperature warnings, etc., to ensure safety. View faults and maintenance prompts for easy upkeep. |

• | EcoFlow Smart Generator 4000 (Dual Fuel) offers intelligent and elegant start/stop methods for various scenarios, providing greater convenience. |

• | Receive 5 safety notifications directly through the EcoFlow app, ensuring remote or indoor users stay informed in real-time. All features(except fuel alerts) trigger automatic shutdowns to prioritize safety for you. |

So far so good.
Pros
- Really quiet.
Cons
- wish the cord was longer. Had to purchase an extra cable. Now the connector is on back order. No one else has it.
