1800W EcoFlow Smart Generator Review: Keeps Your Batteries Charged

I have spent some time with several EcoFlow products; my home’s backup power bank revolves around the Delta Max and an add-on battery. We have reviewed the 400W solar panel and have the Smart Generator in for testing. The EcoFlow Smart Generator is a gas generator designed for the Delta ecosystem to charge while saving you time and fuel.

The EcoFlow Smart Generator will charge the Delta Max or Delta Pro. Charging through a simple and efficient DC charging process increases fuel efficiency, and less energy is lost when the generator is used with the Delta series batteries.

The generator includes an electric start which can be used from the button on the front of the unit, directly from the mobile app, or via the smart charge settings. There is also a manual pull string to start the engine.

This inverter generator weighs 62.8 pounds without fuel and measures 23.5 long by 11.7″ wide by 18.7″ tall.

1800 Watts of power will bring 42-58.8V of DC output with 32A of current. When using the EcoFlow Smart Generator, you can expect noise levels of 56-67dB, which is much quieter than a conventional generator.

One side contains the pull start rope and the on/off switch. The on/off switch will have to be changed to the On position to turn on the screen and start the generator.

The other side includes the engine access panel. Before using, this will have to be opened and set up. The first step is to add oil using the supplied funnel. The oil reservoir is under the orange dipstick; take your time, and use a rag to prevent a mess.

Once the oil is full and all cleaned up, the onboard battery needs to be connected; simply find the two wires and connect, close up the cover, and you are ready to go.

The front of the Smart Generator contains the display screen and a few self-explanatory buttons. The display will be familiar to all EcoFlow users.

There are two outlets: the EcoFlow extra battery port and a standard AC plug.

I created a video to explain how to use the generator and run it through some tests.

The EcoFlow Smart Generator is a must-have addition to all Delta battery users. While it can be used as a stand-alone gas generator, the smart features will save users fuel costs and charge their batteries faster than another generator.

The included AC outlet allows for other devices to be used; just keep in mind the 1800W of output available. Also, keep in mind that since this is a gas-powered combustion engine, it will produce the deadly gas carbon monoxide. Therefore, the EcoFlow Smart Generator should only be used outside or in an unenclosed space. You can read more CO-poisoning prevention tips here.

I love how the generator is designed to complement the EcoFlow Delta series batteries in appearance and use. The smart feature is a game-changer while using the batteries; the generator runs only when needed, charging to the specs set from the mobile app; the direct DC charge via the included cable means faster and cleaner charging.

The EcoFlow Smart Generator is an important addition to the EcoFlow system of power and is easily moved to be used on the go or while camping.

The EcoFlow Smart Generator retails for $1,399; it is available directly from the manufacturer and other retailers, including Amazon.

What I Like: Much quieter than my conventional generator; Electric start; The smart features keep the Delta Max plus extra battery charged according to app settings; Fuel efficient

What Needs Improvement: The generator is too heavy for some to move easily; I wish it included at least 2200W output
