Recent 4 day power outage in hurricane. Kept my freezers going which are awesome freezers, cooling to zero snd holding for hours. Learned enough to know I need a battery as well and maybe I should consider the pro model. Glad I had the max. Easy to wherl around on a cheap luggage rack

I bought 2 of the pro max 2's , like them will work for my green houses during the summer but......will only run the 1500 w heater for about 2 hours. NOT ecoflow fault it's mine did not do my research heater draws 12.5 amps on full setting so 2hrs at that current is not so bad. would buy the pro max 2 again may even get the batteries for the unit.

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.

Bought a few months ago. Unfortunately due to family illness did not have time to check it out. Did bring it up to charge when I got it. Now have tried, hooked to a couple of fans and a refrigerator, ranf for about 30 minutes, worked flawlessly. Still had high percentage of charge.

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.

Delta2Max - Great so far!!

I bought the Delta 2 Max about a month ago, when it was offered along with two free 110 watt portable solar panels. Right out of the box it was super easy to set up, and even on that cloudy day with one 110w panel connected, it was pulling in about 25w. Not much, I know, but it was still exciting!
Realized pretty quickly I was going to need more panel capacity, so I ordered a 220w bi-facial. And then of course I would need more storage, so I ordered another battery!
As it stands right now, when fully charged, the Max2 and the extra battery can run our main refrigerator, a 12v cooler (Iceco), and my complete computer setup (computer, four monitors, printer and scanner) for about a day and a half with no solar input whatsoever.
We've been getting a lot of cloudy, rainy days, so solar input hasn't always been the greatest. On cloudy days with the 220 and two 110s in series, on average I'm pulling in about 150w for a max of 6 hours. On nice sunny days, I can max out at about 380 watts, with an average of about 330 for 6 or 7 hours. This is usually enough to keep all of the above running, but still draining the battery a bit. So...I see some bigger panels in my future - probably two 400W rigid panels. This will double my input capacity, allowing for a total recharge in my short window of sunlight.
Note: we actually did lose power here for about 6 hours overnight one night when I only had about 30% capacity left in the batteries, and the refrigerator kept right on going, no problem!
Charging with 110 is super-quick - usually 2 hours or so. Just for fun, I hooked up my son's gas-powered generator and charged it off of that unit's 110 - again with no problems.
I'm trying to rely totally on solar now, so given the poor weather we're having, and until I can upgrade my input with two 400w rigid panels, I typically have to give it a full day and a half with nothing connected before I can hook up the refrig, cooler and computers again. Then run on batteries for a day and a half. etc.
Overall, great product. Bought it with the intention of using in a small squaredrop camper I'm building, and it would of course handle that task with absolutely no problem. Might buy the second spare battery in the future, just to see how many regularly-running appliances I can switch over to solar on an ongoing basis.
In the next few years, am planning to build a new off-grid-as-much-as-possible home, and will definitely looking to EcoFlow to power it!
