Delta 2 Max

I have had a Delta 2 for about a year and when the Delta 2 Max came out I decided to pick one up with the 2 110 watt solar panels. I love the information that the display on all of the Eco Flow power stations provides. It’s extremely useful to understand the wattage used by various appliances.
I was surprised at how much quieter the Delta 2 Max fans were compared to the Delta 2. The fan noise is not a big deal to me but it was nicer to have them so much quieter. The one concern I have is either the capacity of the batteries or the power used by the inverter. I have plugged in a 100 watt light bulb into the fully charged unit. The display shows about 95 watts used but only 16 hours of run time. The actual time was that or even a little less. That would seem to indicate that the batteries don’t have their full capacity or the inverter is using about 20% of the power. I have not yet contacted customer service about this issue.
Overall Eco Flow products have revolutionized backup power for me. The capability of having power with only using a generator to recharge the batteries is great. This is especially true considering the short recharge times of the Eco Flow batteries.

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 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!

Quiet and easy to use

We recently used our new Delta 2 Max and an extra batter for a Delta Max on a week long camping trip. We ran all of our electronics including a 5000btu window AC on our tiny camper without any issues whatsoever. We have solar on the camper and were able to utilize the 2 solar inputs. We use one from the panels and the second from the DC outlet in the vehicle. Also we charged when need using a small inverter generator. The gray part is that we could charge completely in under 3 hours and run the AC all day for the dogs when it was hot. Without the Delta 2 Max we would’ve been just needlessly running a generator. Lots of features and happy to use this setup for many more years.

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.

I bought this one after watching review videos of different solar generators and comparing specifications. This unit was by far the best option with its lithium iron phosphate battery. I'm a beginner so I've been testing different items around my house to get comfortable with it. I'm planning to take it camping and use the solar panels. Really happy with my purchase.
