I bought this and installed it into my daughter's bus. (Schoolie conversion) It is what we wanted. The only complaint that I have is the way the cable comes out the side. you cannot stack anything next to them within a foot. The wave has a nice 90 degree cable that goes between the battery and AC but the Delta 2's cable sticks about 6 inches out the side.

I found this product to be very well designed, reliable and perfect for my emergency power system case. I especially love the fact that I can remotely monitor the battery life and control the system remotely. I love how I can extend battery longevity based on car battery lithium battery or solar panels. Echo has a number of models that provide great scalability at a decent price range. I love this product. I think it’s awesome.

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.

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.

Im a landscape photographer hobbiest, i go out for a week at a time, Being able to change all my equipment throughout the course of the expedition, is one lese thing to worry about when out in the wilderness.

Got this for power outages. Very nice that it has two solar ports. It does what it is supposed to do. Frame is well built. Very easy to use. I only use solar to charge it. Thank you.

I just got the combo 2 mx + 800 watts charger and 400 solar panel and I full charge most of the time , I whish I could upgrade to a delta pro 3 that should be mind blowing for my ambulance project.

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.

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.

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.
