Greatest product ever, easy to use and very reliable and portable. No issues with fumes or having to get fuel or anything and the changing capability is awesome.

I purchased this unit to back up a 13 CI Freezer as we get plenty of power outages. Thus far it works well and I may soon connected it to two larger solar panels and keep these for camping.

Just ordered second set of panels for charging a battery generator and perfirmance is as advertised. Panels seem rugged enough, design to keep them up correctly might need some work, but funtional.

The unit itself works pretty well. I'd like to see some of the lab features released and a few more things added. Namely the ability for it to keep charge settings even if it loses power. Might pick up the external battery later for added capacity.

We tried it, camping on a non-electric site at Hardin Ridge National Forest. It is mostly shade and the solar is still charging. It has a great battery and great solar charging (110).

We use thisDelta 2 Max to power our off the grid riverside cabin with lightning , tv and fan and sometimes a small a/c unit. We charge it at home using a/c power or we use the solar panels.

Does what Eco flow States. Great product, works. No problems at all. ABLE TYO REDUCE OUR ELECTRICIY BILLS. Unit only take around two hours to charge from ZERO TO 100%. Can't really anything negative about product.

Stop looking. This is it. After extensive research, I came to the conclusion that EcoFlow is the brand I'd choose for a solar generator. Take my word for it, get one.

I bought this to have power when the power in house goes out. We are using it everyday to run our refrigerator to cut our utility some. We have two 400 watt solar panels.

Have been playing with the Delta 2 max and love it so far. My only problem is that I need more cord from the generator to the solar panels. I will order a longer cord and should be happy with it. I love the app and how easy it is to use.
