I am ready for a storm now.

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.

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.

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.

Very happy with this solar generator. I love our Delta Pros but there are harder to move around. This is a great unit to throw in your vehicle and use for whatever your electrical needs are.

Off Grid Power!!!

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.

Just what I needed

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.

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!

Delta 2 Max Does What I Want it to Do
on July 20, 2023
Posted by: bogieb

I haven’t had the delta 2 Max for very long so my review won’t be as in-depth as I would normally do. I bought this unit to run my 1000w microwave during nighttime (when my household solar is not active) plus as a battery backup in case of power outages. It runs the microwave with ease and I have no doubt it will run my pellet stove for quite some time if needed. I’ve charged it both off household electricity and solar panels with no issues.
My one real complaint is, being this large of a unit, I would think that most people will use it for AC power (I could be wrong). But, the main power button, as well as the screen are on the opposite end from the AC and charging sides. However, if you are charging a phone, hey, you can watch the wattages output, the time it can hold at the power drawn and other info from that same end. It’s a minor quibble, but irritates me.
Another irritation (and they all seems to do it), is to have a black package with dark gray writing. I can’t see that with a flashlight and readers. If there were more of a contrast between the colors, I’d have a fighting chance. But again, all 3 of my battery stations, from 3 different makers, are like that.
I rated as 4 stars instead of 5 because I haven't had this long and they are sort of expensive. I haven't found any flaws yet.
