EcoFlow Smart Generator (Dual Fuel)

The EcoFlow DELTA Pro Smart Generator, slated for shipping in mid-October, is a versatile and forward-thinking power solution. It offers dual-fuel capability, running on both gasoline and LPG (liquefied petroleum gas), which empowers users with flexibility in choosing their preferred fuel source. With a substantial 20kWh capacity and a standard LPG tank, this smart generator ensures worry-free backup power, allowing you to seamlessly integrate it into your energy system.

One notable advantage of the DELTA Pro Smart Generator is its remarkable efficiency, allowing you to save up to 40% of fuel when connected to DELTA series and Power Kits. The ability to remotely control and monitor its operation via a user-friendly app provides added convenience. Featuring four distinct ways to initiate its operation and equipped with five security alerts, this generator is engineered with user safety and convenience in mind.

Designed for easy maintenance and engineered to operate quietly at just 56dB from a distance of 23ft, the DELTA Pro Smart Generator offers both practicality and peace of mind. It's a valuable addition to your power backup arsenal, ensuring you have reliable backup power when needed. Please note that to connect the DELTA Pro to the Smart Generator, the EcoFlow DELTA Pro to Smart Generator Adapter (available separately) is required, providing seamless compatibility for a comprehensive energy solution.

The Quick propane quick connect is so great!

NO Fail connections are a real confidence builder. Just spin it on to tank/bottle and press against generator inlet until you hear the clicking sound, then it's off to the races & you've crossed the finish line after you press the button on the generator/iphone/android device that is connected via Bluetooth or Wifi. Your choice 👌 BTW: If you find a demonstrably quieter 1800w max charging dual-fuel generator for the Delta Pro, Enquiring Minds want to know! =☆= PS: Industry standards recommend not using MAX CHARGE capability for these LIFEPO Batteries to ensure longevity. I try and keep under 1200-1500w charging as a loose rule. May take some planning ahead.

It finally got here

The product is wonderful the shipping was great however the communication on when it was going to be here was less than desired. First the generator got here quickly then no communication when the other pieces were to arrive. I sent emails to find out and at first they sent back an email in Japanese.then they corrected it and gave more information after about 2 days. I am satisfied with the product.

Justine Bald

I love the unit so far. Haven’t really had to use it yet It user friendly and has lots of options.

Worth every penny

Great product! I've added this to my off-grid airplane hangar, enough power for three lights, engine heater and wifi router. The app works great, and I can check on status of the battery any time. There price seemed to be high at the first glance, but when I tried to calculate the diy project with similar features and battery capacity, I was just off couple hundred dollars, which I was fine with because ecoflow is more convenient, easy, portable than any dyi

Jocelyn Soul

Product very well made excellent packaging, the best customer service you could imagine. There was no problem with my generator or power station but they called me to make sure there were no issues with their product or if I needed any help using anything.
