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.
One of the standout features of the EcoFlow Delta 2 is its seamless compatibility with portable solar panels. That being said, I would have appreciated the inclusion of the standard MC4 connector adapter; had to purchase it separately. This gave me the ability to harness the power of the sun to charge the Delta while off the grid. The flexibility to charge using solar energy not only saves me money in the long run but also empowers me to go on extended trips without worrying about running out of power.
Speaking of power, the EcoFlow Delta 2 truly lives up to its name. With an impressive capacity, it effortlessly handles charging a multitude of devices simultaneously. From smartphones and laptops to power tools and even mini-fridges, the Delta 2's array of output options ensures that no matter what the situation, I'm always connected and powered up. The fact that it maintains a stable and reliable power output is particularly reassuring, especially during crucial moments or in unexpected power outages.
The user-friendly interface and controls make operating the Delta 2 a breeze. The large, bright LCD screen provides real-time data on input and output wattage, battery level, and more. This keeps me informed about the system's status, ensuring I can make the most of the available energy.
Despite its robust power capabilities, it's surprisingly portable - lightweight and easy to transport thanks to the built-in handle.
All in all, the EcoFlow Delta 2 has exceeded my expectations in every way. It’s definitely gonna make pre-games at the stadium this fall a LOT more enjoyable.
The app works great, the power station was well packed/protected, removed it from the box and it immediately paired with the app, where you can adjust various charging settings. It's amazing how fast it can charge up even at the reduced level to save battery life (~500W vs ~1000W) - which I didn't find noisy at all.
Feels very well built and I expect it to last a long time, especially with the LifePo4 batteries - I'm not even sure I could use the 3,000 cycles up if I really tried. But it is worth having for sure and I highly recommend it as a power station if you're looking for something to have as a home backup for fridges or even just to draw power at reduced rates and recharge devices (laptops/tablets/power banks) during the week.
Top reviews from other countries
The fan noise was a little surprising (loud) when charging the unit, but at around 1200w going in I guess it’s expected, and not a deterrent for buying it.
Would recommend
Customer service is top notch.
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.
