REVIEW – From the time I got my first opportunity to test an EcoFlow product I was hooked. I love companies that push towards being environmentally friendly in their designs and production. I also love companies that make products that are innovative and provide value to their customers. First I got to test the EcoFlow Wave Air Conditioner, then I got to take the EcoFlow Delta 2 Power Station for a spin. Now, much to my delight, I am hyped up on coffee and ready to unbox the EcoFlow Smart Generator – Dual Fuel and see what they will impress me with now. So, here we go!

What is it?

The EcoFlow Smart Generator – Dual Fuel is a smart and efficient generator that accepts both unleaded gasoline and liquid propane as fuel. It integrates seamlessly with EcoFlow DELTA Max, Pro & Power Kits.

What’s in the box?

(See the video in the Performance section below).

  • 1 x EcoFlow Smart Generator – Dual Fuel
  • 1 x EcoFlow Power Station Charging Cable
  • 1 x LPG Connector Cable
  • 1 x Oil Funnel
  • 1 x Tool Accessory Kit (Spark Plug Socket; Double-Ended Spanner; Breaker Bar; Screwdriver)
  • 1 x User Manual
  • 1 x Registration Card

Hardware specs

Design and features

  • Two fuel sources – With either LPG (Propane) or gas, you’ve got two energy sources to deliver higher efficiency, easier use, and fewer emissions.
  • Part of the EcoFlow Ecosystem – Set it to charge your DELTA Pro/Max or Power Kits 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.
  • Stay in the know – With 5 alert methods, including carbon monoxide alerts, you’re always in the know.
  • Seamless LPG set up – Plug-in propane easier than ever with a switch & built-in regulator

This EcoFlow Smart Generator – Dual Fuel is built from ABS/Plastic. On the front, there is a display screen that provides all of the charge and load information as well as connectivity symbols for external devices. There are warning lights for CO and Oil levels as well as the electronic start button, an independent switch for the AC outlet, and a reset button for the entire Generator. Below the controls, there is a proprietary plug for connecting EcoFlow Power Stations for efficient and fast charging, and the AC outlet. In between the 2 plugs, there is a ground screw.

When facing the front of the generator, the right side has a cover that provides access to the engine, for oil filling/draining and access to the internal battery.

On the right side, there is the on/off selector switch, the pull cord for starting, and the LPG connection. On the top, there are two handles, and in between the gas cap that covers the gas tank. On the back, there is the exhaust.


To showcase the performance of this EcoFlow Smart Generator – Dual Fuel, I recorded a few videos. Here is the first one:

EcoFlow has an app that works with many of their devices to provide status and control. Here are some screenshots from the app:

Although I said I could not record the app being used to start the Generator, I decided to use 2 phones, one to record the other, and gave it a shot:

As promised, here is a video of an EcoFlow Power station, specifically the EcoFlow Delta 2 Power Station connected to the EcoFlow Smart Generator – Duel Fuel:

What I like

  • The great design
  • The build quality
  • The handles and portability
  • The Dual Fuel feature
  • The App start/control and autostart features
  • The dedicated Power Station charging capability

What I’d change

  • The oil spout could be longer and angled upwards to make it easier to add oil. A longer neck with a clear “window” for oil level visibility would help users to confirm the oil level and better control the possibility of spillage

Final thoughts

Note: If you get the impression that I am excited and gushing about this EcoFlow Smart Generator – Dual Fuel you would be correct. I have been a fan of EcoFlow products for a while and I know about the great design and quality of their products. While their EcoFlow Wave Air Conditioner and EcoFlow Delta 2 Power Stations are great devices, this EcoFlow Smart Generator Dual Fuel seems next level, at least to me. The ability to fuel it via both LPG (Liquid Gas Propane) and unleaded gasoline and the built-in battery that allows for an electronic start make this generator very convenient and very efficient. Add to that the relative quietness of operation, easy portability and the ability to charge and automatically recharge various models of the EcoFLow Power Stations and you have a fantastic product that will provide off-grid power when you need it most like for natural disasters and storms. Once again, well done, and two thumbs up to EcoFlow!

  2. Good review, but there are two statements you make that need further explanation. For one, you write that this generator is ‘efficient’. How so? Compared to what? You also start your piece by saying that you “love companies that push towards being environmentally friendly in their designs and production” – how does EcoFlow and, in particular, this generator ‘push towards being environmentally friendly’? To me, not much could be less environmentally friendly than an ICE engine spewing CO2 into the atmosphere whenever there’s a power outage – or a battery drops below a certain level.

  3. This type of genset can be had for $500 – $750 and be able to put out near 2000 Watts. I don’t see the huge price differential for a lower powered unit unless the dual fuel aspect has something to do with the additional cost. Down where we live, most generators are running on natural gas and small units like this are typically used for RV type activities. But in a pinch, this type small unit can at least keep the lights on.

  4. Regarding the efficiency, the numbers listed in the review (5.4 kWh per 4 liters of gasoline) indicate a maximum efficiency of around 14%. The remaining 86% of the energy is given off as heat. Small combustion engines are intrinsically inefficient, but a typical car engine will have double the efficiency of this generator. Natural gas, large-scale power production, and battery storage are all much more efficient. There is not much environmentally friendly about this unit if using gasoline.

    1. Hi Hankk,
      This Smart Generator also uses LPG.
      Propane is more energy-efficient and considered to be a green fuel, while natural gas is not.

  5. It always amazes me how US manufacturers of electrical products always market 110V. Products even 90% of the world is on 220 /240 V.
    Same goes for pelple who review the products ; they seem to be only concerned and addressing 1% of the world population.
    I wonder when this retarded attitude is going to change.

  6. A few major issues with this unit as is. Really what your paying for is the “smart” features when connected to their Delta Pro. The problem is 1: It’s auto start feature is unreliable, and occasionally will not turn over, which defeats the purpose. 2: it requires maintenance every 40 hours of runtime or so, and will not start if one of about 20 maintenance updates have not been performed, or at least cleared out via the app, requiring constant monitoring if you use it regularly. It’s overly complicated and glitchy for what is supposed to be a set and forget system, and overpriced if you don’t want or need the smart features of the unit, which don’t really work. I hope they fix these because if it worked as advertised, it would be an awesome product.

    1. I’m testing it now and yes if it doesn’t auto start and stop it’s too expensive, agree, are you keeping yours or plan B? A regular generator..
