The LFP (LiFePO4) battery in the EF ECOFLOW DELTA2 is known for its long lifespan and is typically rated for up to 2000-3000 charge cycles before the capacity drops to 80% of its original capacity. With regular use, this translates to several years of reliable performance.

Yes, the EF ECOFLOW DELTA2 supports pass-through charging, meaning you can use it to power your devices while it is being charged by the solar panel or any other power source.

The EF ECOFLOW DELTA2 is equipped with a powerful inverter and can support high-power appliances up to its maximum output capacity. However, you should always check the power requirements of your appliances to ensure they do not exceed the generator's output rating.

    • Maximum Portability for It's Impressive Power Output
Style: DELTA 2+220W
Review Image by G. K.
Background: Long time Ecoflow customer going back to Delta Pro pre-launch days. Have a few other of the Delta product line including Delta Pro, Delta Pro Extra Battery, Delta Max, Delta 2 Max, Delta 2 (950). Promoted the product through the family and everybody has atleast one in the Delta series. TL:DR: The Delta 2 has a robust inverter for it's weight class. Capacity can be expanded if additional runtime is needed. Solar panel is also a solid product, getting high 80% efficiency in mid winter. Will update again during sunnier weather. For the size and weight a solid product pair for mobility. The Good Delta 2: Solid product with impressive product warranty, robust battery chemistry, and monster of an inverter for the weight package. Any 5-15P corded appliance you can throw at it should be able to run with ease with the only concerning point being runtime depending on the wattage drawn which can be supplemented if I get the Delta 2 extra battery. The Good 220w Solar Panel: Solar panel yielding 80% of rated output in winter weather, looking forward to seeing what this thing can do during the summer with clearer skies and longer days. The Not a Fan Of: Super minor and personal preference but not particularly keep on the elastic bands for the 220w. Have other mobile solar panels that are less temperamental and prone to kick back. Usage Scenario in photo: No need to worry about where an outlet is for a backyard cook out. Plugged in a electric fryer (~1200w) only used for 30 mins, ICECO G20 (all day), and the ECOFLOW Multifunctional Outdoor Camping Light. Delta 2 Unit able to handle all 3 devices and with the additional charging from the panels had enough to keep lights on through the night. ... show more

    • It has helped my family a lot
Style: DELTA 2+220W
This solar generator seems excellent to me, the best thing that has been created. I sent it to my family in Cuba and it has been a great help for them due to the electricity situation that currently exists in the country. Thanks to this equipment they have been able to charge their phones, use some basic devices, and at least enjoy a little more quality of life while there is no power. It is very easy to use, works very well, and has a long duration. I really recommend it. ... show more

    • Well engineered product
Style: DELTA 2+220W
I am very happy with this product. It charges quickly and holds a charge as it should. I have tested it thoroughly and it does everything the manufacture claims. There are areas for improvement but they are somewhat minor: The instructions included give very little detail about the App, how to install it, how to use it and how important it is. The fact is, you really must install the app so that you can update the firmware and to allow you to control the unit. The app also needs some refinement; sometimes the app will have trouble connecting to the delta 2 and sometimes it will show its connected but clearly it is not because the charge and discharge data on the app does not match the screen on the unit. I have found that you need to be very patient with the app, it may take several minutes to connect and many times you have to back out to the first page and click on the delta 2 to get it to update its connection. The solar panel seems to work but, you have to have very bright sunshine and have it aimed very precisely to get any charge. You will , most likely, need an extension cord for the solar panel, otherwise the solar panel will need to be right next to the delta 2 unit. I made an extension cord with some 12 gauge wire and connectors. The app has a feature allowing you to submit questions to customer support. I have sent a few questions this way and the answers I received took a while to get back to me and they were not great. I had to rely on online videos and a lot of trial and error to figure out how everything worked. The product is quite new so, there are not a lot of videos available yet. Overall I really like the product and would only request the manufacturer to supply more information about how to set up and use the product, especially in respect to the app. Update: The app seems to have some bugs I didnt notice earlier: You can change the charge/discharge range, from 0-100% or for example 30-60% (recommended to discharge to 30% then charge back to 60% Quarterly) or what ever you want to set it at. This is a great feature when it works but, lately when I set the app to adjust these setting, it just ignores them. Latter I checked and the settings were now at 4-97%? I have had the same type of issues with other app settings like the charging wattage. I hope Ecoflow will correct these issues soon. Still keeping at 5 stars because it is still best in class IMO. ... show more
