I bought the EchFlow Delta 2 Max with an extra battery. Looking as a backup power source when/if the power goes out. Tested it on various small to medium household appliances and it worked excellent and charged it up every fast. Ready for another use. I also bought last year the Delta Pro with two extra batteries was able to power two refrigerators for 24hrs before needing to charge. Looking forward to making some solar panel purchases next.

We purchased the Delta 2 Max as an alternative to an overhaul of our RV's electrical system. We've used the unit a couple of days and it looks like it will be sufficient to enable us to boondock for two to three days. The case is sturdy, well made and not too heavy given the performance of the components. The app / smartphone interface is great.

I received everything and it all works great. I spent a lot of time researching different brands, options, performance, YouTube videos, etc. and I am very happy with EcoFlow. The only complaint I have is that the Delta II Max does NOT have wheels. EcoFlow sent me a canvas wagon where you can fit the generator inside but you cannot add the Smart Battery with it.

We have been checking out our new Delta 2 Max with add-on battery and solar panels for several days now. Very impressed with the functionality of the overall system and app. The capacity is great to get us through power outages running necessary loads sans A/C. Our gas/propane generator will now become backup to the solar backup. Hopefully, we won't have to use the loud, smelly machine in the future.

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've had my delta 2 max now for 3 weeks and so far I'm loving it. It's a little more heavier than the delta 2 is at around 50 pounds vs 28 for the delta 2 but not to heavy for me to carry it around without a problem. I've used it to power various appliances around my house such as a microwave oven, a convection oven, hotplate, hairdryer, space heater and a room size air conditioner and it's handled everything like a champ! The fans are alot quieter than the delta 2 fans also. The fast charging is nice at around 10% it took a little over a hour to charge to 100%. I love the eccoflow app too! It puts everything you need to know about the unit and what it's powering at your fingertips. Overall it is a great unit with lots of awesome features and works really well for what I use it for. I am well pleased with my purchase and would recommend this product to others who are looking for a portable powerstation.

Recent 4 day power outage in hurricane. Kept my freezers going which are awesome freezers, cooling to zero snd holding for hours. Learned enough to know I need a battery as well and maybe I should consider the pro model. Glad I had the max. Easy to wherl around on a cheap luggage rack

I bought this and installed it into my daughter's bus. (Schoolie conversion) It is what we wanted. The only complaint that I have is the way the cable comes out the side. you cannot stack anything next to them within a foot. The wave has a nice 90 degree cable that goes between the battery and AC but the Delta 2's cable sticks about 6 inches out the side.

Recently experienced nearly 24 hour power outage; my brother kept refrigerators, etc. going at his house for several days with only a two hour charge of his DELTA 2 Max unit at my house when power was restored. Long story short, I ordered the DELTA 2 Max and additional battery; of course I haven’t needed my system yet, but it’s nice to feel prepared. Shout out for the prompt deliveries of both components.

I bought 2 of the pro max 2's , like them will work for my green houses during the summer but......will only run the 1500 w heater for about 2 hours. NOT ecoflow fault it's mine did not do my research heater draws 12.5 amps on full setting so 2hrs at that current is not so bad. would buy the pro max 2 again may even get the batteries for the unit.
