I bought the new Delta Max 2 last week 7/11/2023, and it is incredible it is running my lights, internet connection, security cameras, induction stove, hair dryer, it will run my window unit ac refrigerator pretty much anything you throw at it. I have five 100 watt solar panels right now I will be getting five more to keep it charged up while I am working. It charges up extremely fast with the AC outlet. I've been watching Eco flow when they first came out when they came out with Delta Max 2 I just had to get it. So if you're thinking about buying one this would be the one to get thanks for everything guys!

I have the Delta 2 Max and 2 extra batteries. I really like the options in the app from being able to limit charge rate and AC always on, and much more. One extra battery fits nicely on top of the Delta 2 Max, but the Dela 2 Max does not fit snug on an extra battery, I wish it did. Overall I recommend. It does not take the place of a true UPS, but I already had a UPS anyway. My only complaint so far is one of the extra batteries came with a bad display, but I guess I'll keep it. I don't want the hassle of a return and I use the app anyway.

I used solar panels, charge controllers, AGM batteries, and inverters for YEARS when I built out another camper. I was always searching for direct sun to 'refill' my batteries. I was such a pain—a real distraction to my travels.
Now, I use an Ecoflow battery generator and their 800-watt charger. Today, I installed the charger. It was very easy compared to all the old components. So, I only need to take a short drive to charge my battery generator fully.
My battery generator and charger are both connected to Ecoflow's app. I can watch the progress of charging and discharging. The app is very professional and provides way more information than I need. But it's nice.
The battery generator eliminates the need for solar panels, a charge controller, and an inverter. The batteries in the generator are much better quality than the old AGM batteries. I'm so happy to have made the switch.
I would recommend their products 100%; I was lucky to have purchased them during Prime Days and saved a considerable amount. They provide quality products.
I'm a happy camper without thinking about the charge of my batteries. Life is good.

Delta 2 + 800w Alternator Charger

I purchased this combination about a year ago and feel like I need to write a review after using these products. Prior to upgrading to this setup; I ran two Jackery (250w and 1000w) units for my power needs while camping. Switching to the Delta 2 setup minimized the amount of equipment I needed. It also provided plenty of power to run my fridge and charge any other electronics I needed charging. However, this is not the reason that prompted a review. The Delta 2 with the 800w Alternator Charger earned its worth when it got me out of an otherwise expensive situation. I was about an hour away from home running trails when I happen to damage my alternator. Because of this; I was slowly draining my battery and feared I’d have to pay for a costly tow. I had happened to leave my Delta 2 in the truck that weekend and it came in clutch. It was fully charged due to it being hooked up to the Alternator Charger. I was able to reverse the charge and run the truck off the Delta 2 for an hour until I made it home. I charged the Delta 2 every night to be able to drive to work and back until I was able to get the alternator replaced. Needless to say, the Delta + 800w Alternator Charger earned its worth. I highly recommend this setup to the point that I don’t need to run a dual battery setup since I have this to rely on. If you ask me, this combination is worth the money if you spend any time off grid or off the beaten path.

A nice addition to my EcoFlow family!

I previously had a River Pro as I live quite rural and power goes out a few times a year from storms (spring, summer, and winter) and I wanted something to intermittently run the fridge, freezer, and sump pump with. Earlier this year we were without power for a good chunk of the day and moving the battery back and forth between the three was getting annoying. I picked up he Delta 2 Max so that I could run the fridge and freezer with it, and then use the other just for the sump during power outages, not two weeks after it delivered we were without power again for several hours and it worked like a charm.
I also used it to till our 15x15 ish pumpkin patch this year as I have a cheap electric tiller that was well within the power delivery capabilities and instead of daisy chaining 200ft of extension cord I just put the battery in the yard, ran a 10ft extension cord to the tiller, and safely tilled away from it.
LOVE IT! Maybe someday down the road we'll bump up to a whole house solution!

Heavy, but gets the job done

Works amazing and does 99% of what I ask of it in the form factor I need it, but the lack of 30 amp outlet and 24v car charger output are shortfalls I'd like to see resolved in a future product update.
Moving this thing around also isn't the easiest thing. I can carry it one handed for a trip to the car, but anything beyond that, (or any use case that would drain the battery in one sitting) and I find myself highly unmotivated to use it.
For now, it is the perfect backup power supply to my fridge and deep freezers. I bought this for electricity during emergency situations and it will definitely do the job!
