Style: DELTA 2
I have 4 Ecoflow portable power stations and they all work great. I like the Delta 2 units because they don't weigh too much and are a great value when on sale. Pros: Will power pretty much anything in your kitchen with the 1800 watt inverter. Charges quickly in 1 hour off of 120 volts. It has 1024 Wh battery but only weights 27 pounds. Has 120 volt, 12 volt, and USB outputs. Great for camping, travel, or powering appliances in your trailer. Con: The inverter consumes about 10 % of the power which is pretty normal for inverters. Will not run some power tools because of the high power surge lasting several seconds.

Style: DELTA 2
I read a lot of reviews and watched many videos before buying the Ecoflow Delta2. My main use for this Delta2 is for overnight camping trips and use as a back-up power in case of black-out conditions to run some equipment like Refrigerator and be able to heat food using the microwave. Delta2 doesn't have the battery capacity like Delta Pro but with a good solar panel it can definitely come handy when required. One can always add an additional battery that again works seamlessly to extend the battery capacity or buy the Ecoflow Smart Generator. I was debating between Bluetti EB70s and Ecofow Delta2. The reason I bought Delta 2 over Bluetti was the battery capacity. Delta 2 provides 1024WH as compared to the 716WH from the EB70s. Delta 2 met the power requirements that I was looking for. I could not find any offering by Bluetti in the range of 1000WH capacity. Delta 2 was of course more expensive than Bluetti but the surge power (also called X-BOOST by Ecoflow) is really high. So running a microwave for a short time or a coffee machine at a campsite or picnic is not an issue at all. I bought a combo pack (Delta 2 and solar panel). More about this combo later in the review. The other reason was the 5 year warranty that comes with the Ecoflow Delta2 vs 2 years for Bluetti. Some models from Bluetti do offer 4 years but were expensive for my use. Below are a few things I like about Ecoflow Delta2 after using it for sometime. 1) Construction - This is a solid built product. The bottom edges have these rubber bumpers for extra protection. The form factor is designed well to fit in the car. I hope the handles were not protruding out as they are now and were more integrated into the main box. The box is strong and one can easily put heavy items on the top without any issues. With the LFP battery and 3000 battery cycles, the Delta 2 will last forever. 2) Display - It's big and clear. Very easy to read even on a bright day. All the connections that are turned on are shown on the display even when a load is not connected but for USB only when a load is connected, the icon is displayed. Not sure why only the USB icon behaves like that. Not an issue at all but just wondering why a different behavior as compared to other connections. 3) App and Connectivity - The phone app works great and it's very easy to use. There are so many options that you can set via the app. Connecting the Delta 2 to the app was a breeze. It connects to WiFi without any issue and also to bluetooth. The app shows correct data 99.9% of the time. Once in a while you have to refresh (close/open) the app to get the latest data. It is very rare but I did notice it. When the WiFi is available, the Delta 2 connects via WiFi. If there is no WiFi connection, it automatically switches to Bluetooth connection. The connection is just seamless and you are always connected to the Delta 2. 4) Charging - Delta 2 can charge at a whopping 1200W to be ready from 0% to 100% in about just 80 minutes. The fans do kick-in to dissipate all the heat generated during this fast charging. I personally charge the unit at 500 W with fan running but much less noisier and may be better for the battery life. The solar charging can go up to 500 W. I don't have enough solar panels to check that max limit but this can be a really handy feature during a blackout conditions or with limited hours of sun during camping. One can charge the battery before leaving camping or any other work. Charge while driving from the 12V DC outlet in the car (Also known as the Cigarette lighter port) and the battery will be 100% when you reach your camp/work site. 5) Output Connections - There are more than enough connections that one can use, in my view. With a massive 1800 W peak capacity and 2700 W of surge capacity, I think you can run almost any home appliance with this Delta 2. The provided ports like USB A, USB C, Power Outlets and 12 V (Car type) are good to power any device you may have. Now coming to the combo I got. I bought the combo of Delta 2 and Solar Panels that were rigid. I was not happy with the size and format of rigid panels so I reached the Ecoflow support team. Even though I made that choice and now wanted to get portable panels, the Ecoflow team worked with me. The support team was amazing with quick responses and answering all the questions I had. It was good to see Ecoflow believes in good customer service that still cares about their customers. One of the best customer service teams I have worked with. One option that I would like Ecoflow to add will be to set the discharging and charging percentages even when connected to the power outlet. I would like to connect a solar panel for charging and connect my garage refrigerator to Delta 2 and use the battery power. If the battery falls below a certain level (let's say 30%) it can charge via the power outlet, else the refrigerator can keep running via the solar power. This option is provided when you connect a Ecoflow smart generator to Delta 2 but not when connected to a power outlet. I hope Ecoflow will implement this feature in the future software update.

Style: DELTA 3
The Delta 3 is nice! I purchased this unit in March 2025, and added it to my growing EcoFlow collection. I have a few River series units and a Delta 2 with an extra battery. The Delta 3 arrived quickly, and setup was a breeze. EcoFlow offers an optional, free-to-use mobile app, which I have, and it recognized the device immediately after start up. The D3 works straight out of the box too, so if the mobile app isn’t your thing, it works just fine without it. Since it’s a 3rd generation unit, the Delta 3 has a lot of new features available in the app that my first and second generation units do not. I particularly like the remote shut-off feature, where I can go in the app and turn off the device in case I forget. Another new-to-me feature is the real-time power usage and history. Since I recharge the unit using solar, it’s great to see the history and daily solar power generated by the connected panel. I also like that all of the AC and USB ports are on the front of the unit. This is great since I store the unit on a heavy-duty shelf against a wall with my other devices. The Delta 3 is great, however I do have some small critiques. I did get two error codes during my first week of use. The first day I connected solar, I plugged the panel (EcoFlow Flexible 100W) in the night before. The next day, I woke up to error code 303, which is likely related to the inverter based on codes for previous generation Delta units. The mobile app explained the error and offered troubleshooting instructions right away. After the reboot, the device worked without issue and I haven’t see that error since. On a different day, after charging the D3 via AC power, I briefly encountered error 471 when unplugging the power cord from the outlet. It’s a quick error that appears on the D3 screen but doesn’t last long enough for the mobile app to show any information. I’m not sure if it’s actually an error or just a power blip when unplugging. It doesn’t happen every time, but I have seen it a few times since March. In general, I’m not worried about these two errors. The Delta 3 comes with a 5-year warranty, so if I have any issues in the future, I’ll reach out to Customer Service for support. Overall, I think the Delta 3 is a solid addition to the Delta series line up. If you’re new to EcoFlow and considering this unit, it’s a great one to start with. Note I said “start with”, because you’ll love it enough that you’ll want to add more devices to your collection! Definitely look for a Daily or Lightning Deal and EcoFlow coupon checkboxes on the item listing to get the best price. Not to be confused with the Delta 3 Plus, which is another great unit, the Delta 3 also comes in a 1500Wh capacity in either the black or silver finish. If you are trying to decide between the Delta 3 1024Wh unit (this one I’ve reviewed) and the Delta 3 1500Wh unit for a similar price, definite go for the larger battery. Whatever you choose, don’t forget to register your unit for warranty and *actively read the user manual* to learn how use and maintain your device for many years to come. Enjoy!
