Style: DELTA 2 Max 2048Wh
I just received the DELTA 2 Max, and right out of the box it made a strong impression. The charging speed is the first thing that stood out to me. When I plugged it in for the first time, the percentage jumped so quickly that I actually double-checked the display. Getting to 80% in under an hour is not an exaggeration — it really does it. The overall build quality feels premium. The LFP battery chemistry was a major reason I chose this model, and even as a new owner, you can tell it’s designed for long-term durability. It gives a sense of confidence that you’re not buying something that will fade out after a handful of uses. I immediately tested it with several of my own devices — my computer setup, my monitor, some studio gear, a few household items — and it handled everything without even blinking. Seeing it push out clean power to multiple things at once reassures you that the 2400W rating is not just theory. The number of outlets also makes it practical; I never felt limited or cramped trying to plug in several items at the same time. The quiet operation is another pleasant surprise. When it’s charging, it’s barely noticeable. I had it sitting a few feet away, and it never became a distraction. The expandable capacity is also a smart feature. Even though I haven’t added extra batteries yet, just knowing that I can turn this into a much larger backup system if needed is a big plus. Overall, as a new owner, everything about this unit feels solid, fast, thoughtfully designed, and genuinely capable. It delivers exactly what I hoped for when I ordered it.

Style: DELTA 2 Max+220W Solar Panel
I couldn’t be anymore happier with my unit. Charged within 45 minutes to 95% from 26% plugged in to DC. Charged with solar panel up to 85% within 4.5 hours from 23%, sun wasn’t that hot in Michigan but a lot faster than my Jackery solar panel charging my explorer 1000 which I love for portability. I bought the Ecoflow to run my sewing machine to do shows while traveling and it works perfectly well for my needs. I am a full time solo traveler therefore both my solar generators get a good workout. A full charge will last me 2 weeks + Hats off to Ecoflow for a fantastic solar generator.

Style: DELTA 3 Max
The media could not be loaded. This is a great Unit and can do most everything in your house. Now this is not a full home backup for days, but can run most appliances in a home. Fridge, microwave,air fryer,pressure cooker,fan,TV internet,small electronics. No problem. Great for on the go. Solar input,AC,DC car charge or pure sine wave generator to charge unit. Can move room to room easy or take camping or on the go. Love the size of the screen. This could last about a week camping and attach couple of solar panels and you are set with power. Great for outdoors where there is no outlets. Think Christmas lights being plugged into the unit. Make Hot chocolate or coffee at festivities. Parade floats for lighting items up. Small Con is only one solar input compared to the Delta 3 max plus has 2 solar ports Weight: Weighs about 48 lbs, but for this size of unit pretty good portability still. Can use a wheeled dolly to move it also.

Style: DELTA 2 Max+220W Solar Panel
I started with the ECOFLOW Delta-2 by a mishap, but it was easily cleared up by their superior customer service. I now am the proud owner of the Delta 2 MAX. I have some photos of the readings from a gloomy/overcast/cloudy day, where I was still pulling some wattage to charge the system (around 35-45 watts) Then some sunny day shots of the panels set up using their built-in stand=works very well, especially since it is actually a built-in stand from the protective/zip up cover/storage for your expandable panels. They fold out easily and set up just as easy. Make sure to take advantage of the dual surface capabilities! I have pumped out 190+ watts using reflective materials that project the sun's rays unto the back of the panels as well. With the sun at 10-2 pm, and no reflective materials set up yet, I was cranking out 140-160 watts, as shown in the pics. I do not remember if I got the 190+ watt shots, but I will check my phone and post if I can find them, if not, I will get some as soon as I drain the MAX and have to charge it back up. These panels are rated at 220W, and saving you from boring details of specs etc., that equates to around 140-160+- watts during full sun in California. If you need to charge it fast for a trip, use the wall plug, it CRANKS the watts, I have a shot where its at 1152 wats from the wall outlet in my house. The max is portable and light for what it pumps out, "quietly". I am around 6' 200lb weight lifter type guy, and it is light for me, I can carry the generator in 1 hand, and the panels in the other, so many of you fellow muscle guys & gals will be able to do the same I'm guessing, otherwise, just make 2 trips or get a buddy. I also show some shots of it running a dyson vac & washing machine at the same time=EASY for the max. I ran my fridge with the D-2, so the max will have no problem with the fridge as well. The customer service is amazing, responsive to you within 24 hrs, sometimes within the same day=few hours even. They are so professional and kind, even fun to speak with. All have been from the Philippines, and I have YET to receive anything less than superior customer service quality from the Philippines, its as if they were born with superior CS skills built in. I am very grateful for their abilities to handle any and all issues I had after my initial purchase, and the follow up is just as high quality. AND, the issues were minor, and few. Mainly my misunderstanding of specs/etc. as I am quickly learning about the solar products. They have been a HUGE help & friends to my new venture into solar power. YES, I said FRIENDS! Think of one of your best friends, and they stand behind their products like a best friend would stand behind you. Why do I mention this? Because I know how I felt about purchasing my first solar generator, the anxiety & plethora of questions in my head. I have been researching for a few Years, and I am 100% glad I chose ECOFLOW, and I have complete confidence to put MY NAME on their customer service and product support. Bottom line, you CANNOT GO WRONG with ECOFLOW products if all their CS reps are like the ones I spoke with, PLUS their products are performing up to and beyond expectations! At this point, a few months in to owning the MAX, I am extremely happy, and satisfied with every aspect of their company, how often can any of us say that today? I will be investing in a whole home system sometime in the near future, and ECOFLOW is at the top of the list.

Style: DELTA 3 Max+220W Solar Panel
I own a few of Ecoflow's power stations, and this is an awesome addition. Software is awesome, 2.4kw inverter runs most of my appliances. And the 2kwh capacity is perfect. And this is actually lighter in weight than its predecessor, Delta 2 Max. Despite the lack of extra battery capability, and only one solar input, the lower price reflects the subtractions and is perfect for those who don't need the extras.
