EcoFlow with solar panel
Excellent EcoFlow power station with solar panels. It charges fast, is easy to set up, and provides reliable power during outages or outdoor trips. The solar panels are efficient and convenient, making it an eco-friendly solution. Great quality, portable, and worth the investment. Highly recommended

Another great addition to the EcoFlow Delta series!
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!

It's all in the details!
These power stations have really come a long way. You can now set schedules to turn them on and off. Turn on the Ecoflow Delta 3 Classic during peak hours when electricity is most expensive then off during off-peak hours all from the app! You can monitor usage and even get storm warnings too. With all these new features, it's only a matter of time before we start calling them "smart" stations! The feature that caught my attention the most is the near-instant (<10ms) switchover when the power goes out essentially making the Ecoflow Delta 3 Classic a viable UPS backup power source. It gave me the idea to hook this power station up between my fridge and my van. Under normal conditions, the fridge would draw power from the van itself. But now if I turn off the van for any reason, the power station automatically kicks and continues to power the fridge! And when I turn the van back on, it again automatically switches back to drawing power from the van! I no longer have to get into the trunk where the fridge is and switch out the cables manually. It is all seamless and truly hands-off now! One less thing to worry about on my road trips! Beyond that, I really have to give props to Ecoflow. Right from the unboxing you can tell that you are getting a quality product. The tape sealing the box that holds the charging cable has a small flap at the edge to make it easier for you to peel it off. The charging cable itself is hefty and clearly labeled. The bag that holds the instruction manual is not made of just any cheap plastic but the kind of plastic that has that soft velvety touch to it. Even the foam inside the box is of high quality. It is soft, it doesn't make that grating noise when you handle it, and it doesn't break apart and have little bits flying all over the place. The Ecoflow Delta 3 Classic itself has two nice-sized handles at the top on each side making it much easier to lift--especially in tight spots like, say, the back of a minivan. Two generous non-skid pads cover the bottom of the power station. On the input side, there is a cover that swings up to open and that can be tucked right into the power station itself and out of the way. Also, the two three-pronged outlets are oriented on their sides to flare outward so that whatever you plug into them won't get in each other's way. It's just genuine thoughtful designs throughout. All of this might seem trivial at first, but when taken altogether, it shows that Ecoflow is a company that cares. They stand behind their products and you can rest assure that you are getting great value for your money.

A second update has been added to the end of this review. A quick update: The power station sat for a couple of months after the most recent charge. Today I decided to discharge and recharge it. It still showed 100% charge when turned on and ran a small portable room air conditioner for over half an hour. It still had 50% charge and didn’t get even slightly warm. The AC unit draws about 900 watts. This is truly an impressive device! Original review: I have used this power station only for a few days and so far it has proven to be easy to use and it delivers the performance advertised. It is quick to charge, even at a much lower charge rate than maximum. It is not particularly loud when charging. I have tested it by using it to power my CPAP machine. In this application, it is silent. I calculate it would be able to operate the CPAP machine between 4 and 7 nights. My machine heats the humidifier water and the breathing tube. Other machines might do even better if they don’t have these features. We recently experienced a once-every-30-year ice storm and were without electricity for about 4 ½ days. I wish I had this power station during the blackout, but I am quite confident it will serve us well now that we have it. Our freezer just barely kept most if the food safe, but running it for an hour or two once or twice a day would certainly extend that safety margin considerably, and the power station could probably handle that for a day or two and still provide adequate cell phone charging and enough time on the CPAP machine to keep me safe for a few nights. The unit itself was well-packaged. The instructions are clear, and the app fairly simple and useful. The unit itself is not visibly intrusive, it’s quite compact and seems very well made. These days we are almost shamefully dependent on our electric and electronic devices, which are getting very energy efficient. Also this dependency is much more pronounced as we live longer. All in all a great purchase, which I hope never to actually need to use, but I am very sure we will need it sooner or later. Second update: About 14 months after the terrible power outage last year I bought a second Delta 2. The first one has performed perfectly, particularly during a fairly lengthy power outage a couple of months ago. I have been considering how to increase my reserve capacity: Should I get an auxiliary battery or a second power station? The price is about the same, but having 2 complete units seems to be more flexible. I had an opportunity to get a second Delta 2 for about ⅓ off the regular price, so that became my choice. It’s so impressive how the power station pretty much sets itself up once plugged in, the app is opened on my phone and I touch h to the + button to add a new device. This is now my third EcoFlow unit because I bought a River 2 just for my CPAP machine about 6 months ago, and it has kept me safe on quite a few occasions. I feel very confident that we will be able to manage well during any future power interruptions.

Excelente producto, su carga es rápida, he tenido corte de energía por la zona donde vivo y la estación de energía me ha ayudado mucho, la última vez conecté un pantalla de 65 pulgadas, un ventilador, el módem y carga de celular duro más de 4 horas, ya no continué utilizando porque llegó la energía eléctrica. En cuanto al vendedor excelente, llegó en tiempo el producto y en en excelentes condiciones.

Producto usado. Tenía marcas de dedos, daños en la pantalla y polvo. La caja tenía marcas de haber sido abierta antes. El producto no entra en la garantía del reembolso por lo que no se puede hacer nada para tener el dinero de regreso.
