Having a RiverMax and knowing EcoFlow, I expected a lot...and my expectations were exceeded. Made my purchase based on my good experience with EcoFlow and the specs of the Delta2. When it arrived I was impressed by how quickly it went from 30% to 100% charge. Then once charged, I couldn't find a device it wouldn't power. And once I add the extra battery, I will have more confidence that the Delta2 can get me through the next power outage. Still like the River, but am extremely pleased I added the Delta2.

For Christmas 2023/2024 my wife bought me a new 3D printer (Bambu Lab X1 Carbon 3D) and wanting to make sure I had everything I needed she purchased the combo pack which happen to come with the Delta 2. Now sure over the last few months it was used for various small things around the house, but this "mistake" proved invaluable during the early morning hours of 5/25/24 when my town was hit by multiple tornados. I was lucky to be a few miles from the main damage paths, but we lost power. Power remained out for nearly 5 days at my home. After we emerged from our storm shelter the first thing I ran to get was the Delta 2. It became our go-to power source each and every night. During the day I powered the house from a generator I had purchased (learned from being directly hit from a tornado 6 years prior), which charged the Delta 2 (it charges super fast btw), but at night when all you could hear were generators running, my house had this little magical black box running 3 box fans, charging phones/tablets, and powering an LED light source. Not to mention when I woke up I had a hot pot of coffee waiting on me. All of this and it had 6-7 hours of spare runtime left! With that being said I highly recommend the Delta 2! Thanks for making such a great easy to use product!

I originally bought this to be a power source for camping. However, i got to use temporarily until my power came back on to run my pellet stove. Easily movable and easy to use. Download the app and its a good way to keep an eye on usage and anything else. I like that I will be able to expand it if needed. Right now it's good for what i need.

Purchased my Delta 2 in late 2022 and used it extensively over 8 days of power outages in California’s nine back-to-back atmospheric river storms of Jan 2023. Primarily ran a 24 cu ft fridge which it did with no problems. Could run the fridge for 5-6hrs on a single charge. Used a small portable generator to recharge the Delta 2 and when that generator failed, charged it off the 12V outlet in my hybrid vehicle (slow; but, it worked). Truly my power outage MVP - great to run the fridge without stringing up extension cords to the outside. Convenient size and weight. The fast charge times made the most efficient use of my portable generator’s run time and fuel. The Ecoflow app with Bluetooth worked well - being able to set the Delta 2’s charge rate was very useful when charging other items on my portable generator. Remote monitoring from a comfy chair was nice as well. So, all in all, the Delta 2 was my power outage MVP.

After extensive use, I can honestly state the Delta 2 is amazing. It is used mainly for its portability in property management and electric power tools but I use it to power smaller kitchen appliances and electronic devices as well. I am NOT a fan of the folding solar panels which are so very expensive. But the solar generator is a very fine product and I have already demonstrated and recommended it to others.

I bought the Delta 2 a little more than a month ago to help run my refrigerator and freezer in the event of an outage. I know it’s on the light end for this in terms of available power, but my plan was to buy another one and I will rotate them (Charge one while the other is running.) I like how light the unit is; light enough for my wife to move if I’m not there. I looked at another popular brand, but was concerned that my wife wouldn’t be able to lug it around, weighing in at around 60 lbs. So far I’ve tested it with my coffee maker and my indoor refrigerator and it worked as advertised. It ran my frig for 9.5 hours before running out of power. The advertised recharge time was also accurate. I’ve not yet recharged it with my two 220w panels. That’s next on my agenda. All in all, happy I made the purchase. Debating now if I’ll get another Delta 2 or try a Delta Max to get some extra power and longer run time.

I waited for this power station to hit the market. Having owned several smaller Ecoflow power stations and some from another well-known brand, I like the Eco-flow better. It charges much faster and has an app that I can use to see how much power is left when it is out of reach in the back of the truck. It was a little more pricey but since it should last 3000 cycles instead of the 800 cycles of the Delta originals, makes this a better purchase. I just tried it out on my 2007 21cu ft house refrigerator and it lasted 12 hrs and had 10% power remaining. I also bought the extra smart battery but haven't yet used it.

I love my new Delta 2. The Delta 2 is a second generation update of the original Ecoflow Delta 1300. It's many improvements include longer lasting much safer LFP Lithium Iron Phosphate batteries, an expansion battery port, more solar input (500W) and an even faster charging time than before. They have made many noticeable improvements under the hood as well, integrating circuit boards to cut costs and keep the same weight (LFP batteries are heavier!), improving efficiency - yet the Delta 2 is less expensive than the original Delta 1300! 
I have two Delta 1300's from the original kickstarter campaign - they really revolutionized the solar generator business and set a standard all the legacy companies have since been trying to catch up with. Before Ecoflow solar generators looked not unlike modified gasoline generators - that is industrial and clunky. But the Delta 2 like the rest of the line, look much more friendly, they blend ergonomically into any home environment rather than looking out of place like they really belong in the garage. 
But the killer feature has been the fast charging. The group of 20 somethings that founded Ecoflow had worked at drone maker DJI together, and observed the biggest pain factor was how long it took to recharge batteries. And so they figured out fast flash recharging in under 2 hours, 1.6 hours on the original Delta. The new Delta 2 can flash recharge now even faster than the original, in an hour and 20 minutes, all Ecoflow solar generator charge in under 2 hours, even in an hour for some, yet there are still competitors out there that take over 10 hours plugged into the wall. 
I did observe that when the Delta 2 is cool it charges a lot faster. Checking the internal temperature with the phone app to be 96°f, it charged at near 1200 watts on the meter, slowing down a bit at 80%, eventually fully charging in exactly an hour and 20 minutes as advertised. However if you discharge it at a very high output it heats up the batteries (I did a torture test and ran it at 1200 watts flat to 0%, with a hair drier in 30 minutes.) Then you have to let it cool down before it will recharge. After a cool down rest period, the still somewhat warm Delta 2 charged at a steady 600 watts the whole way. It took a little longer at 2 hours, but no complaint here. 
Great improvements, nice price point, expandable, lasts longer. If you are a fan of these kind of devices - you will love your new Delta 2 too I think!


I purchased the EcoFlow Delta 2 to power my CPAP machine for camping trips and to power CPAP and refrigerator during power loss at our house. We had good success with the Delta 2 camping to power my CPAP for two nights including lighting and phone charging. We had a 5 hour power loss in December of 2022 and the Delta 2 was able to power the refrigerator along with Keurig coffee maker and microwave to prepare breakfast and lunch. I also purchased the bifacial solar panels and have recharged the Delta 2 with the panels located along a south facing wall. If we have an extended power loss during a snow or severe weather event, I have a small tailgating generator to run periodically during the day to recharge the Delta 2 for day use while it is running appliances since it has pass through capability and then transition to Delta 2 only at night to power CPAP and refrigerator while sleeping. Solar panels would be used for extended camping trips or extended power loss at house if generator runs out of gas or breaks down.

I have only had my Delta 2 for a week but so far I am very impressed. I also have the Anker 555 Power Station which is a good product but in comparing the two similarly priced products believe the EcoFlow Delta 2 is superior. The Delta has more charging options and the fast charging of the Delta is impressive. I look forward to putting this to use in remote locations.
