Compact, portable, and easy to use, it’s the dependable solution for outages, off-grid travel, and everything in between.

Higher Efficiency with DELTA Pro 3

The EcoFlow Smart Generator 4000 becomes significantly more efficient when paired with the DELTA Pro 3. It delivers 3200-watt DC fast charging and improves overall charging efficiency by up to 40 percent compared to traditional fuel generators.

Energy-Saving and Eco-Friendly Performance

This smart generator is designed to save fuel and reduce emissions. When used to fully charge the DELTA Pro 3, it saves up to 40 percent more fuel. With the same one gallon of fuel, it can produce one kilowatt-hour more power than conventional models.

Smart and Automated Power Backup

When connected with the DELTA Pro 3, it supports four intelligent backup modes: customizable start and stop, photovoltaic priority mode, smart reverse charging, and automatic night-time start. These features ensure continuous and hands-free backup power, especially during the night.

Dual Fuel Compatibility for Versatile Fuel Options

The generator runs on both gasoline and LPG, allowing users to choose their fuel source based on availability. This flexibility is ideal for emergencies and extended use during fuel shortages.

High Energy Output for Extended Usage

Using a single tank of gasoline, the Smart Generator 4000 can produce up to eight kilowatt-hours of energy. This is enough to power essential appliances for up to eight hours at 25 percent load.

Remote Monitoring and Control via App

Through the EcoFlow app, users can control and monitor the generator remotely. The app provides real-time data on energy consumption and system status, and it sends safety alerts such as carbon monoxide detection and high or low temperature warnings.

Multiple Start and Shutdown Options for Convenience

The generator offers five methods to start operation: manual pull cord, electric button, reverse charging from a portable power station, app start via Bluetooth or Wi-Fi, and scheduled automatic start.

It also supports six shutdown methods: manual knob switch, one-click electric shutdown, automatic shutdown, scheduled shutdown, low output detection shutdown, and app-controlled shutdown. When paired with a third-party portable power station, it will automatically shut down once charging is complete and the output drops.

Real-Time Safety Alerts and Automatic Protections

Users receive five types of real-time alerts through the app to ensure safe operation. Most alerts, except for fuel-related warnings, trigger automatic shutdowns to protect users and connected equipment.

Compact and Portable Design

The generator features a compact design with an ergonomic pull-rod, making it easy to move and store. Its small footprint allows it to fit neatly in storage areas without taking up too much space.

Complete Accessory Kit in the Box

Each unit includes the EcoFlow Smart Generator 4000 (Dual Fuel), an LPG hose with regulator, an oil funnel, a tool kit, and a user manual for quick setup and operation.
