The EcoFlow Delta 2 Max is all I hoped it would be to power my home office should the power go out. The technology seems second to none. I also bought the 400W solar panel. The two combined give me the power needed to run the essentials.

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!

Have had this for about a month and a half now, charge is extremely quick when plugged into AC. Charges decently fast when hooked up to solar, I have a combined 720 watt input. So far everything seems to be operating correctly, I did have one issue where it dropped its Wi-Fi connection and I kind of had an issue getting it reestablished. I reached out the service and they gave me some ideas of how to get it to work again, I got it to work again. I do have two extra smart batteries attached to this Delta 2 Max. With everything hooked up it does take quite some time to charge on solar. Which is to be expected though it has to feel quite a lot of power reserve. This will come in handy when the power goes out and I need to maintain critical items in my home. All in all I think it's probably a great product, only time will tell though.

I have three ecoflows. Two Delta 2 Max and one Delta mini, I bought them because we have frequent power outages. They are a great option when power is out to run essentials. Performance is awesome and I intend keep adding more units to my house. These things are built like tanks.

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.

We have been checking out our new Delta 2 Max with add-on battery and solar panels for several days now. Very impressed with the functionality of the overall system and app. The capacity is great to get us through power outages running necessary loads sans A/C. Our gas/propane generator will now become backup to the solar backup. Hopefully, we won't have to use the loud, smelly machine in the future.
