Power outages, camping trips, RV adventures, and off-grid situations all have one thing in common: reliable electricity matters. The EF ECOFLOW DELTA 3 Classic Portable Power Station provides a substantial 1024Wh energy capacity in a portable package designed for home backup and outdoor power needs.
With 1800W of output and up to 3600W of surge capacity, the DELTA 3 Classic is designed to power a wide range of household electronics and appliances. ECOFLOW’s X-Boost technology can support loads up to 2600W under compatible conditions, helping expand the range of equipment the power station can handle.
When connected to AC power, X-Stream charging can take the unit from 0% to 80% in approximately 45 minutes, according to the manufacturer. For off-grid use, the DELTA 3 Classic can also recharge through solar panels, with the manufacturer stating approximately 2.5 hours using a 500W solar panel under specified conditions.
The built-in LiFePO4 battery chemistry is designed for long-term durability, with ECOFLOW rating the battery for more than 10 years of daily use. An integrated Battery Management System helps monitor and manage the battery for safe operation.
For home backup applications, the <10ms UPS function automatically switches to battery power when grid electricity is interrupted. This makes it suitable for keeping compatible electronics and other essential equipment running through brief power interruptions.
The ECOFLOW app provides remote monitoring and control, allowing users to monitor energy consumption, manage charging schedules, and access features such as Storm Alert and Self-Powered Mode.

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.

Works great and is well built!
The functionality on this is amazing! It has several sockets and phone charge outlets. We used it on our camping trip and it did not disappoint. We charged it at home and it was easy to use.We were able to charge the phones, power a mini fridge, lights and some tablets/laptops. We came home and still had energy left ! It seems to have an excellent run time and battery life. The portable battery is not that big, nor very heavy and we definitely prefer it over a generator. I’m planning to get the solar pads too. Im not sure about the lifespan of this kind of item but the box is very well made and seems great quality.

SOLID Lil MACHINE!!!
This Delta 3 Classic is a great little machine! I got it when there was a chance we’d loose power due to an ice storm. We ended up not needing it. However I did put it through some tests. It ran our 65″ tv for over 4 -5 hours before going down to 20%, ran both our cpaps for 2 nights, ran our tankless water heater through several showers, coffee pots etc. And the app offers very nice features that let’s you customize your use!I plan on adding a Delta 3 Max with solar panels to the arsenal. No rush! We’re in southeast USA. Severe storms do not come through here very often. Overall very happy with this machine!

Really useful and well made solar generator.
This is a good solar generator. Be advised however that this unit is not compatible with an extended battery. It is meant to be stand alone. If you want expandability you need to get the delta 3 max bare minimum to have that option. Otherwise it is great. I have used it to power lights along with a computer and it worked flawlessly. 19 hours of run time when powering 1 led bulb, one compact flourescent bulb, a laptop, a led string light set, a rope light set, and a 35 watt USB c power brick. I ran a 1200 watt portable heater along with the said items and it had a 1/2 hour run time. I also use it as a U.P.S. to keep my wifi routers, printer etc online if a power outage occurs. It does this without skipping a beat. It takes an hour or so to charge from a standard 110 outlet. Have not tested it with a solar panel yet as I have to wait to purchase that. But if it performs as well as it has so far it will be wonderful. I am extremely pleased with its performance so far. This is only after 2 months of use so I cannot comment on how long it will last but so far the specs for it are dead on. The ecoflow app is also a great feature and it alerts you to power outages and the device status. On the app it will show you what the output wattage currently is and the remaining battery life. If plugged in it tells you how much current is going into it and well as out (usually the same going in and out.) Would have given it 5 stars if it was compatible with expansion batteries to expand the capacity. Otherwise it is great for what it is and what it does.

Awesome Power station
The media could not be loaded.
This is one of the best power stations that I’ve own. I was a little hesitant because of the price and also because I’ve paid a lot for power stations in the past that didn’t work too well. But I’m glad I took a chance on this one.So, when I bought this, my intention to use it was for our camping trips and perhaps Coachella next year. I just wanted charge and run little nick knack like multiple phones (6 total) and blow up our air mattresses for a few days without it dying on us like the ones I had prior. After testing it out for a few days, those little charges seemed like it’s no match for it. So, I decided to take it up a couple of notches. I was able to operate my electric leaf blower with no issues. I decided to have my KBBQ out door with my electric grill and ran the fan at the same time. No problem. We were able to enjoyed that for at least 2 or 3 hours and still have way more than half a tank of juice left. So, I decided to test it out with the fan and the mini fridge cooler at the same time. It was able to cool my fridge down from 68 to 42 (my setting) in 45 minutes while running the fan as you can see in the video. After running it for 5 hours straight on full strength, I still have 50% juice left. The set up was easy. Just plug and play. It has enough outlets and charging ports for important equipment incase of power surge outage. The battery life lasted longer than I expected. The size is compact and portable for outdoor usage. The only thing I regret was that I didn’t get the solar panels with it.

I’m really impressed with this power station! ⚡️
I’m really impressed with this power station! ⚡️ The battery life is excellent, and it charges super fast—about an hour as advertised. It’s powerful enough to run multiple devices at once, which makes it perfect for home backup, camping, or emergencies.The build quality feels solid, and the LiFePO4 battery gives me peace of mind for long-term use. I also love the variety of ports, especially the USB-C. Overall, it’s reliable, convenient, and definitely worth the investment. Highly recommend! 👍

Excelente calidad y suficiente para usos básicos.
El envio fue bastante rapido pero debes estar en la casa porq hay q firmar la entrega,tienes q dejar de trabajar porq no hay un tracking ni comunicación para saber a q hora vienen,por lo demas el producto es de buena calidad,dura 8 o 9 horas con cosas basicas,un tv unas horas,ventilador,luces,laptop,cuando pones micro,se lleva bastante de la carga.,pero para un camping esta bueno,no tanto para temporada de huracanes ni nada de eso,pero tiene buena calidad. En mi caso la mande para cuba,les contare q tal les ira con ella alla. Pero la recomiendo para cosas sencillas
