Overall this is an excellent unit with plenty of features and options to customize how you want to use it. I'm personally using it for smaller devices so the 1800W capacity is nice but not necessary. New firmware updates have been brining even more features to the unit which is a plus. I tested the battery capacity and it exceeded the 1024 Wh stated capacity, so you're getting what you pay for. Also the LiFePO4 battery chemistry is far superior to other cell chemistries and is what utility-scale battery storage containers are using. Solar charging works extremely well. I was using (4) 100W Ecoflow panels in the winter and was able to get about 395 Watts using my professionally mounted patio chairs. Here's some of my recommendations to get the most life out of you battery: - If you're storing it for long periods of time, maintain the charge around 40%. - Most utilities set the charge settings to be 98% and discharge down to 2% and they cycle batteries almost daily. I'm not running my unit that hard but keep the 2% and 98% setting the same. - Minimize the depth of discharge. Discharging from 100% to 0% will degrade the battery faster than discharging from 100% to 50%. If you're cycling the battery every day I'd recommend doing further research. - Enable slow charging. It adds less thermal stress to the components and there's no point to use the fast charge unless you're in a hurry. - You may notice it will discharge for a while around 0-1%. The same thing happens with grid-scale batteries. I would recommend discharging the battery fully, recharging to 100%, then discharging it back to 0% at least 2 times. This will help train the the battery control unit to be more accurate. Other observations: - The unit is fairly heavy but the carry handles are well built and I felt comfortable carrying it one-handed by a single handle. -I use the unit for powering my modem/router and the UPS feature switches fast enough so they maintain power upon loss of AC to the unit. There is a very short delay (30ms I think per the manual) so critical non-capacitive loads may cut out. - The fan is fairly loud/high pitch around the max output. Around 1000 watts it sounds like a regular fan. - There is an 'AC Always On' setting. This will keep the AC outlet relay energized and will slowly drain the battery, even if no AC loads are on.

I have several Power Stations, even some I built myself, but nothing come close to this. EcoFlow has really outdone themselves. The feature rich unit is strong, powerful, yet extremely lightweight and even expandable. I bought the Extra Battery as well. The ease of use and portability make this my favorite hands down. This unit packs a ton of power and features into an really small package. The WiFi feature allows me to keep an eye on it from anywhere, Just like my off grid solar for my home. I can easily look to see the SOC, loads, solar input and many settings. The Delta 2 along with the Extra Battery are the best companions for off grid RV’ing, parties, worksites, power outages, emergencies and so much more. I reach for the Delta 2 and its extra battery when I need power to go from now on. I have portable solar panels to keep it topped off. This is by far my favorite power station, and I highly recommend it to anyone looking for one. It gets 5 stars from me!

I’ve had this for several months now and I’m very pleased with its performance. It serves as a back-up power source for my home theater system and several other components such as a Wi-Fi extender and home theater peripherals. It has plenty of power to be able to operate the devices for several hours.

I got the Delta 2 during the launch event, not realizing that just two weeks later I would be depending on it during Hurricane Ian. During the storm, we lost power and right away, I pressed the Delta 2 into service. The unit kept my refrigerator on for over 9 nine hours while the storm raged outside. Once the worst of the storm passed, I was able to start the generator and used it to recharge the Delta 2 in just about an hour. I love the app which shows how much charge is left and details about power input and output. I am now on day three without power and have already been through three-four cycles of using the battery and recharging it. It's currently powering my desktop computer and 43" monitor and it shows it could go another six hours. The Delta 2 is amazing, and it literally saved my bacon during Ian.

Very good power supply, I used the 400 W power supply from a Chevrolet 1500 to charge the power bank with no success. Then after passing through a 36 volt power converter it was fine. see Attachment. If there is a 48-volt 10-amp power converter, the charging power can reach 400 watts.

We bought this before a big snow storm. We were going to lose power. Having to lose a fridge and freezer worth of food was not an option for us. Having the eco flow as a back up power source that was safe and not run on gas was a game changer! I now have peace of mind when we lose power. Great for charging the phones and computer for work and entertainment. So happy we made the decision to finally purchase this. I’m excited to take this camping with us this summer!

Living in the TampaBay area, I have just gone through Hurricane Ian. By luck I ordered my Econflo Delta 2 on September 22. I arrived today September. I took it to a friend that has power, it was fully charge on about an hour. Right now I have my refrigerator connected, laptop and cellphones charging and pool pump connected. I cannot wait I to use breathing machine tonight for a decent night of sleep finally. I am back to living a normal life, thanks to My Econflow Delta 2. I would recommend this little gadget to anyone. Sis silly if you live in hurricane areas

We bought the EchFlo 2 and an extra battery a couple of months ago and are so happy we did. We had a huge snow storm, lost all our power but the EchoFlo saved us!! We were able to hook up our refrigerator, garage freezer, and our laptops so we could continue to work remotely. Love it!!

great station. when there is no light, it easily copes with the fact that the TV, router, pump for heating work. even the electric kettle works to heat water. almost no noise. fast charging from the network. compact. I recommend to anyone who often turns off the light

I bought the Delta 2 after a day-long power outage, sleeping without my CPAP and worrying about the food in my fridge. I did a lot of internet research and it seemed th ebest fit for me for peace of mind, as well as supporting the CPAP on camping trips. While I've not had to use it yet, I can tell you that it is fact to charge, holds the charge like a champ (no power drain over a month) and is easy to move around the house. I love the display and the many ports to draw power from. My only regret is that the app does not seem to work with my phone/wifi network. Which I don't really care about, but thought would be cool.
