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.

Awsome, this is a powerhouse!

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!

Pretty good product for on peak power shifting

I got this to help shift my on peak power usage during expensive summer pricing. I have my refrigerator, router, tv, surround sound system, and a few lights plugged into this 24/7 and it powers them no problem. The fans are relatively quiet and the app makes it nice to check info about the unit. My biggest complaint would be solar charging.expect about 50-75 watts to be wasted in ac-dc conversion so if you get 200w solar you are actually only charging about 125-150. Other than that it’s a great unit and charges fast via AC wall outlet. Haven’t taken it camping but it can also be used anywhere since it’s only about 50lbs

I'll give the 110w 5 stars based on my Brother's 130W he bought. We both used the 130W panel sharing it back and forth over a 4 day weekend. We charged his EcoFlow River Max battery and my Domtic PLB40 battery. We had our respective jumpers/adaptors to connect our respective batteries alternating every other day to the 130W solar panel. We used an aftermarket 10 ft solar extension cord from Amazon and it as a huge help. I suggest getting 20 feet. It worked great! As for the 130W ...We both were going from 30% power to 90% power in 3-5 hours. We were using 40 and 50 liter capacity refrigerators in 90+ temps during the day and 65 degrees at night. It was sunny the entire time (Grand Junction CO) . We did not reposition the panel. We just tossed it on the roof of the pop-up. Super easy to use, compact and a great value. I'm expecting the same with the 110w. If any solar panel lasts longer than 5 years of overlanding I'll be happy, I do think the 1 year warranty is nice but requiring me to keep the original box is stupid should I need to send it back for a warrant issue.

EcoFlow DELTA 2 Max Portable Power Station

This Delta 2 Max is all you need for all those road trips or at home for any electrical emergency. I am really impressed with this product, but you will say that it is very expensive, and yes it is expensive but when you have it you will say that it is worth it because it is very efficient and durable that it comes with a 5-year warranty, just enough to get more for your money, thanks

The panel works well and so does the tilting stand, so long as the angle isn't too large. Some sort of a velcro mechanism might be helpful to prevent slipping out when windy. I'd also like to see the panel carry case include a large external zipper pocket that could be used for cables and such. As it is I have to transport my River, this solar panel, and then another carry case with cables and adapters. Just a thought to consider.

Ecoflow Delta 2 Max - Great Performance

The EcoFlow Delta 2 Max has the perfect capacity, along with the ability to add additional battery storage, for my home needs during emergencies. I want the essentials to be power backed up for my house in these times. With the flexibility to add additional batteries as needed, as well as integrate into the ever growing EcoFlow ecosystem of products, made it a great choice for the needs of my family.

Unparalleled power, energy storage, and value!

I am an existing first generation EcoFlow River owner, who saw the need to upgrade, to a more substantial home backup system. I compiled an extensive side-by-side comparison, of the full line of EcoFlow generators. After comparing the specifications of each generator type, along with their energy storage per dollar spent, the Delta 2 Max was the clear choice. When paired with the Delta 2 Max Extra Batteries, this generator offers unparalleled power, energy storage, and value!

Delta 2 Max -- A Great Choice!

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.

Best portable generator for your money

The Delta 2 Max is all you need for all those road trips or at home for any electrical emergency. I am really impressed with this product especially how easy it is to set up, how convenient it is to check the battery status and output through the ecoflow app, and how it can power pretty much anything I plugged into it may it be my portable fridge, full size fridge, fans, iPhone, MacBook, etc. I also like that it goes from 0% to fully charged quicker than most portable generators of this size
