The generator that puts preparation first.

For extreme extended blackouts, you might need even more than EcoFlow DELTA Pro or DELTA Max to stay powered. That’s where the Smart Generator comes in to charge them up when you’re all out of other options. It’s up to 25% more efficient than other generators too¹, saving you fuel, fumes, and time.

Recharge & power simultaneously.

While you’re charging up your portable power station, you can still use the 1800W outlets on the generator to keep your essentials powered. The 4L gas tank is enough to charge DELTA Max to full twice still leaving some left over to power your essentials in the meantime.

Safety first.

The Smart Generator puts safety first. It features a carbon monoxide alarm to signal if you have enough ventilation, and will auto shut off when CO levels are too high. It also has an alarm to let you know when you need to top up the fuel so you’re never caught short.

Smart. Really smart.

The EcoFlow Smart Generator isn’t just any generator. When your DELTA Pro/Max falls to a set charge level, the Smart Generator can automatically kick in to charge up your unit, then turn itself off when the job’s done. All this is customizable and controllable within the EcoFlow app too.

Made with you in mind.

Generators are traditionally a hassle to maintain. We built the Smart Generator inside and out to remedy this problem.With a single door on the side of the unit, you can access everything for easy maintenance.

The bright LCD on the front makes it easy to check up on your generator too, it displays output data, run time remaining and more.

Interior Design

Each wire is secured and plated in copper, a key consideration in case of knocks and jolts, all while providing extra cooling. The 4 fans up auto-regulate to breathe ventilation through the unit for extra cooling.

The carburetor is an essential part of the engine and should be adjusted by a dealer with professional knowledge, data, and equipment. Changing the carburetor when working at high altitudes: The atmospheric pressure may reduce the amount of air that carburetors intake when running in high-altitude areas. This may cause its performance to decline and increase fuel consumption. It may also affect the spark plug and make the engine hard to start. If at an altitude different from when the engine was certified, emissions may increase over an extended running time. Modifying the carburetor may improve its high-altitude performance. If you continuously operate your generator above 3281 feet (1000 meters), contact your after-sales service dealer, who can modify the carburetor.

Turn the maintenance cover knob to open, take off the maintenance cover and check whether the positive and the negative wires of the battery are connected correctly.
