Purchased the Delta 2 MAX when it was released, and happy that I did. It has been a great device with the ability to power most all of my needs. My only gripe is, when charging the time to full capacity reads incorrectly. I have to unplug the solar panels, shut the unit off, then turn it back on, and then replug them in for it to read accurately.

I use it mostly to power my Dometic CFX3 95DZ when off the grid. I can get around 2 days, depending upon the outside temperature without using solar to charge the battery. I bought this to replace my Jackery Explorer 1500 and have no regrets. I like the App connectivity and configuration/display options. I don't know if I missed a setting, was outside of bluetooth range, but it would be nice to configure an alert to be notified when you have x% battery remaining. The 20-Amp charging feature is nice, but I'm not sure I have to many 20-Amp outlets to take advantage of it. It will definitely trip a 15-Amp outlet. Another thing I like about it over the Jackery is that it seems to be sized/shaped better for storage and transportation with the handles on the side. The only other thing that is not certain is if the DELTA Max cover is the official cover for the DELTA 2 MAX, since the website doesn't have a specific accessory section for the 2 MAX.

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.

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'm a professional drone pilot and was looking for ways to charge drone batteries on the go. Specially, my big drone DJI M300 requires a lot of power to charge batteries. When I tested the Delta 2 Max charging my batteries, I was impressed that the charger to see how much power it draws (750 W). I can easily charge the batteries up to three times with a single charge on the Delta 2 Max. I did another test with my house refrigerator which draw 85 W and can be powered up more than 20 hours with the Delta 2 Max. Super impressed with the power and quality of this.

I had just received my Delta 2 Max (D2M) a week before we had an unexpected and unexplained power outage. It was right at dinner time as food was going into the oven. Fortunately I had the D2M at the ready and routed a 20-amp power cord from the D2M to my transfer switch. We were able to run the 1700 watt toaster oven for approximately 45 minutes along with lights, computer, a refrigerator, and a freezer. This drained the battery in the D2M to about 30%. I had also recently purchased the EcoFlow Dual Fuel Smart Generator (DFSG) and hooked it up to the D2M to give it a test, too. It came on right at the 30% mark I had set in the EcoFlow app. It took about an hour to charge the battery with propane. The generator then shut itself off automatically when the battery was fully charged. Dinner was served and power eventually came back on a few hours later. Both the D2M and the DFSG performed as expected with no problems. I highly recommend this set up. Before I would have to run my gasoline generator continuously during an outage. Even though it has an ECO mode, it would still burn 3-4 gallons per day. With the DFSG and a Smart Extra Battery (SEB) I will likely only need to run the generator 2-3 hours per day, and that can be reduced with solar panels. NOTE: I prepared for this EcoFlow setup by drilling a hole in my exterior wall. This allows me to keep the D2M and SEB inside but connect them to the generator, transfer switch, and solar panels outside. The PVC conduit has caps when not in use.

Bought the Wave 3 and Delta Max 2 very impressed with the quality of the product. We had a bit of a snag with logistics. So I reached out to EcoFlow and within a couple of hours the issue was resolved. The product was delivered the next morning. Should make for a great addition to the family camping trip this weekend!!!! 5 Stars!!!!!!!

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!

Lightweight and good instructions for set up in parallel or series configuration. Would like to have a little more stability when fully opened. Outer two panels flop and can drag the unit to the ground. Perhaps a lightweight foldable prop for each end.

This has been an awesome power station for our off grid camper and work needs. We have used it for our 12v fridge, lights, computers, tools, smoker and microwave. It powered our 12v fridge for over 36 hours and still had 15% power remaining. I definitely would and have already recommended this to others.
