Industry’s Fastest 3200W DC Fast Charging System
Higher efficiency, more reliable when connected with EcoFlow DELTA Pro 3
Unlock unmatched power and reliability with the EcoFlow Smart Generator 4000 (Dual Fuel) and EcoFlow DELTA Pro 3 hybrid setup. Featuring industry-leading 3200W DC fast charging and up to 40% improved efficiency, they excel in various scenarios, from backup power to on-the-go charging.
More Energy-Saving & Efficient
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 EcoFlow DELTA Pro 3. This means that with the same 1 gallon of fuel, this smart generator provides 1kWh more power.

Customizable start/stop - 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.
Night-care mode - 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.
PV-priority mode - 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.
Smart reverse charging - 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.
Dual Fuel for Double Peace of Mind
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.
Gasoline Power - The smart engine produces 8kWh in single gasoline tank, you could power your home appliances for 8-hours at 25% load.
Propane Power - 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.
