We recently owned a Goal Zero 1400 unit and had it only a relatively short time before it pooped out on us and had not really used it much! We researched other power station options and decided to purchase the Delta Max. Best purchase we’ve made. We bought it originally to supplement power during our camping trips. It was a life saver during a recent hurricane being able to power our CPAP machines when we lost power for several hour during the night. Charges nearly instantly (maybe 90 min) compared to other products. Can’t wait to see how long this unit will last and how many uses we will get!

One of the best things about the Delta Max is my experience with their technical/customer service representatives. I initially was going to purchase the Delta 2 and at the last minute decided to upgrade to the Delta Max. My cancellation of one product to change to another was seamless. Now knowing that I have one of the leading generators gives me peace of mind. It is extremely easy to use and set up. X-boost is amazing. Being able to regulate and choose the source of charging adds so much variability to the Delta Max. Again I would like to recognize representative Qing in Support. Thank you so much!

Understanding that not every customer is adept at power stations and create the manual as such would be helpful. Also, the print is light and small, also not helpful I like the design of the Power Station having handles on each side. At 48 pounds it’s pretty heavy for me but the handles make it easier to lift. I did buy a plastic moving dolly with swivel casters.. I keep it on that so I can easily move it around when needed. I haven’t had to use it yet but I imagine I will this winter as my area is prone to power outages. Fingers crossed it’s as powerful and dependable as people say.

The delta max is a BEAST!! Used during an 8 hour power outage in my neighborhood. Delta Max worked like a charm. It powered my full size fridge plus big screen TVs, internet and modem all night long. Would love to get the extra battery for the Delta Max someday.

I've been testing this thing out since I bought it, and I'm really impressed. We have a few outages a year and I'm tired of being dead in the water when they happen and worried about food spoiling. I've ran our whole entertainment system for several hours, and plugged in the fridge which appears like it'll stay powered by itself for around 20 hours. This gives me peace of mind that we'll have juice the next time the power goes out. Happy with the purchase!

I live in an area with frequent power outages, so I have purchased multiple EcoFlow power stations in different sizes for to run different appliances. The units are all great, but the Delta Max is my favorite and is what I would recommend to someone who wanted only one unit because it has the best combination of price, power storage, size and weight.

My only complaint is there is only one 12v dc car port. To be most efficient, I want to run as many dc appliances as possible. Instead I have to run the majority of my van through the inverter which consumes additional power. I would want a minimum of 3 12v dc car ports.

I watched a lot of YouTube videos on the EcoFlow products. The "Wave" air conditioner was rated excellant. especially for my camper van. A few videos recommended buying the Delta Max battery instead of the smaller battery that attaches to the Wave as I would get more hours of running time with the Wave. I bought the Max and the connecting cable and it works great! I am a full-time RVer and travel in my camper van with rooftop solar panels, across the U.S. I like the fact that I can do remote camping and still have A/C. And the same if the electrical grid goes down due to heat waves and storms! And with temperatures increasing every year, I look at purchasing the Ecoflow Wave and the Ecoflow Delta Max with longer running power, a necessity!

I recently purchased an Ecoflow unit and I feel that I am a little better equipped to tolerate an interruption in electrical service now. It will allow me to cook a few meals and recharge my phone if necessary. I cooked a portion of my dinner yesterday (rice cooker) and it worked very well. In fact, it stores enough power that I could repeat that a few times if necessary. It even powered a space heater for a while. I just wanted to see if it would do that and it worked nicely. I would recommend it to anyone.

Product works as advertised. I thought I could power my fridge for longer than 14 hrs but it looks like I'll need more than this. The 220 W solar panel performed well but after 7 hrs of direct sun it charged the Delta max to 30%. So I'll need more panels. It's a very nice unit but not as powerful as I'd hoped.
