EcoFlow Reviews 

Support when I needed them were super helpful. Ticket process was painless even though the final resolution took a little while. DELTA 3 Plus itself I would highly recommend. Great software and solid build quality. Overall, I’ll definitely be buying further products from EcoFlow.

Absolutely appalling warranty support from EcoFlow.

When I plug in my Delta 3 to charge, it trips my household electrics. It also no longer charges at all, so the unit is essentially useless.

This isn't even the first fault. Around a year ago, when the device was just 2 months old, I reported that the unit would suddenly shut itself down despite still showing around 28% battery remaining. EcoFlow asked me to provide a video.

The same fault recently happened again, so I finally captured it on video and contacted EcoFlow 2 weeks ago with the evidence they had requested.

No reply.

I chased them five days later.

Still no reply.

I have now contacted them for a THIRD time, copying multiple EcoFlow departments.

This is a DELTA 3 sold with a 5-year warranty and purchased directly from EcoFlow. A company selling large portable power stations should surely treat reports of potentially dangerous electrical faults as a priority.

I've now given them five working days to deal with the warranty claim before I escalate the matter through my card provider.

One final point: EcoFlow seems to post the same generic reply to negative reviews asking for an order and case number, despite there being no way to reply to their response.

I already have a case number and will happily provide it privately if EcoFlow contacts me. So let's see whether they actually read this complaint and deal with it, or simply paste the same generic response below.

I will update this review with exactly what happens next.

I own a few delta pros and havent had too man issues so I just recently ordered another pro. I also ordered their portable a/c unit. Complete garbage by the way, a box fan blows colder than this does. I also purchase the alternator charger and smart adaptors, and paid extra for their shipping insurance. I never received the adaptors, EcoFlow told me to handle my dispute with fedex, which I paid them extra for. They have the absolute worst customer service ever, 800# is a joke and then they just blow you off in an email. never a call back. BUYER BEWARE HORRIBLE COMPANY WHEN YOU HAVE AN ISSUE

I have the ecoflow delta mini and the wave 2 and really happy with the products and with the warranty as I have had an issue and they are truie to his word.

I have invested a significant amount of money in the ecoflow system, and the products themselves are great.

However, the customer service is truly the worst I've experienced.

I was sent opened/used solar panels that had been thrown in the back of a lorry wrapped in cling film (!)

They do not provide working tracking for their deliveries so you have no idea when things will arrive.

They advertised a 3 month app trial with new purchases but then refused to honour this.

All the above has required me to send countless emails, support staff don't appear to communicate with one another and just keep asking the same questions and seem incapable of understanding questions / information. In total I have sent almost 50 emails to ecoflow to try and resolve these issues!

I am now looking into my consumer rights to return everything I have purchased, which is a shame as the products are good - but their customer service is so poor I want nothing more to do with it.

I would advise anyone considering investing to look instead at the new systems from Anker or Bluetti.

And there's probably more!

I've been through all this already and you thought sending me a novelty powerbank worth about £2 and a discount voucher worth less than the ones you give every customer anyway was appropriate so I don't hold out much hope.

Very good support from EcoFlow.
My DELTA 2 developed a battery cell problem and could no longer be repaired. After troubleshooting and reviewing my case, EcoFlow offered a good solution and arranged a brand-new replacement unit.
Communication has been clear and helpful throughout the process. I appreciate the way my case has been handled so far.

My EcoFlow Delta 2 unfortunately developed a fault during the summer, which was naturally disappointing. However, what truly impressed me was the way EcoFlow's customer service team handled the situation.
Throughout the entire process, the support team was responsive, professional, and genuinely committed to finding a satisfactory solution. They kept me informed, answered my questions promptly, and worked hard behind the scenes to resolve the issue.
What really stood out was their willingness to go the extra mile. After reviewing my case, EcoFlow arranged for a brand-new Delta 2 replacement, demonstrating a level of customer care that is increasingly rare today.
While products can occasionally experience issues, it is how a company responds that defines the customer experience. Based on the service I have received, I can confidently say that EcoFlow stands behind its customers and their products.
Thank you to the entire EcoFlow support team for your persistence, professionalism, and customer-first approach. I would not hesitate to recommend EcoFlow to others.

Do not buy from this company.
At first I thought this was the best purchase I had ever made, delivered promptly, easily installed.
Then after 11 months of trouble free usage, 6 months of free electricity, the Stream Ultra developed a fault, fortunately I was monitoring the system and the smell of hot electronics warned me . the unit was too hot to touch, seemed to have no thermal cut out and was not channelling the PV to the grid or the batteries, I tripped the breaker and disconnected the solar panels.
I contacted EcoFlow via email, it was a Saturday, and got a reply that it was good I had isolated the unit and they would pass it to the technical dept, response 3-5 days.
I phoned on Monday morning and was told that disconnected panels wouldn't be damaged, but I had to wait for the technical Dept.
The Tech department contacted me and asked for various details ,open circiut curent, ok i can measure that ( 45.6V, each panle), short circuit current, erm you supplied me with the panels , you should know that, maximum power point voltage, ditto.
Then Im told that there is a problem with the inverter, yes I knew that, they cant send me a 11 month old replacement, and cant arrange a repair, so will I accept a refund with a depreciation of 11 month from the 120 month guarantee.
Ok , can you credit my EcoFlow Uk account with that money so I can get a replacement.
Answer no.
We cant give a refund til you return the unit.
But my system is currently inactive.
So I bought a replacement from Ecoflow Uk, to show I was genuine,sent them screen shots of the receipt, but no , they can't authorise a refund till they get the unit back, and Ill be sent a label in 3-5 working days.
After sales service is terrible, multiple different people who don't read the case, product is potential dangerous. Guarantee is worthless.

Latest update is another "f*** you ,its your problem, we have your money".

EcoFlow technical service is poor. It has been 3 weeks since we tried to get the DFUX unit with many batteries working properly. But, it still isn't performing as it should and Ecoflow customer tech service is extremely slow at replying to solve their issues, taking 2 days for replies that don't answer your question(s). Each step they take hasn't worked. I am waiting again at least 24 hours for a reply, and their reply will not answer the question or problems based on the last 7 or 8 times we've done this merry go round. It is as if they don't read your questions or just choose to ignore your questions in writing. It will be another day or two to get any reply. If I call in I get another person that somewhat starts at the beginning again, ending up with no fix. Maybe it will work as advertised long after the 30 day refund and return window, and dozens of hours of wasted time trying to get it fixed with Ecoflow. They are a bit scary and fortunately most of it bought at costco with their 90 day return policy.

Absolutely shocking, purchased a delta pro 3 in June 2025, it broke down and stopped working after 2 months. They collected this and sent a replacement unit in Sept 25. The 2nd unit broke down in April this year and we had lost faith in the product. They offered a refund once they had arranged and received the unit back. We are now end of Aug and they have still not collected the unit. Despite multiple days waiting in for the courier who has failed to turn up now in 5 occasions that have once again said they will escalate this and arrange for a courier to collect. Oh and apparently you cannot speak to a manager or supervisor on the phone. Do not touch this company.

I paid 7,000 euros and ordered the Delta Pro Ultra inverter with two batteries. For 3 months they didn't emailed me. Finally they said that they are not able to deliver the product and they have no idea when it will arrive in stock. It is taking me 1 month now to refund my payment and I still didn't get it. They saying that they had a billing request issue, then they made me await for another few days, and after they confirmed that the refund is made - I did not received my money during 2 weeks and they refuse to send me the proof of bank transfer because they do not refund the funds,

Ecoflow EF3 Pro just out of 2 year warranty .No spares available will not even look at it. Only option they offer is a replacement at 5% discount . Why would anybody buy a product from this company .

Ecoflow is unable to support their product line through their current customer service model. They have a poorly considered website, with a mismatched product line and poor communication on their website to define what a person is purchasing. They also have major issues with their product line, such as their very fragile "**NEW**" 220watt bifacial solar panels that are recently discontinued. We have two of these panels since June 2026, and one is cracked despite treating it with kid gloves, keeping them in their case for travel, with a foam shipping inserted for extra protection and wrapping them in blankets, while transporting them in an upright position.

We purchased these panels and a power station in May for an off-grid camping trip that happened in July. We tested the panels at home before camping and were impressed with the wattage input into our power station. In good sun the panels would sometimes exceed 500watts. The problem that we learned later is that the panel construction is very fragile. We have also learned that the customer service of Ecoflow is terrible.

After we tested these panels and the Delta 3 Max we put them all back into their foam inserts and into their boxes for storage, before heading to camp. In fact, we thought about keeping them in the boxes for transport to camping, but realized the boxes take up far too much space in our FJ Cruiser.

We learned about the panel fragility problem after packing the panels to go camping. We stacked them upright, like they came out of the box with the junction box facing upwards. They were packed in their carrying cases, with a shipping foam inserted for extra protection. We then put a thick blanket over the panels for even more protection. We put the power station beside them, and put bags with clothes and other soft items around it, to act as a cushion and keep the power station in place.

When we arrived to camp in Shushuap, there was a boil water advisory, so I got out the Delta 3 Max power station and we boiled ten quarts of water. Impressively, the power station boiled this water using an 1800 watt max induction cooktop, with an eight inch coil. The boiling took the battery from 100% down to about 37%, which my cousin and I were very impressed by. After boiling water I tucked the Delta Max 3 back into our vehicle and we proceeded to have dinner.

The next morning I got up with plans to use the solar panels to charge the Delta 3. I went down to the beach with the panels and the power station in a cart. It was 0730am. I set up without noticing any issues and saw that with the sun low and haze in the air I was only getting about 50watts with both panels. So, I decided I'd pack things away and wait till later. My wife had joined me, and our son was still asleep in the tent.

As we packed up the solar panels I noticed a crack in one, emanating from the junction box. I immediately said to my wife that we will have to warranty the panel, because the soft way we treated them up to this point gave no reason for this crack to exist. We proceeded to continue using both panels, but noticed a major drop in wattage from the cracked panel. We also noticed that through use, the cracking grew worse.

After arriving home from our two week camping trip I immediately contacted Ecoflow customer service. This is when the real issues arose. They said they would not take the panel back on a return for a new panel, nor give me my money back to put it towards another panel. So I asked what the solution was.

They said they would honour the year warranty and send me a new bifacial 220watt panel. When I looked on their website, the panels I had purchased a few months ago no longer existed. So I asked them if they had discontinued the panel, to which they gave no reply. They proceeded to tell me they could replace the broken one with a new one. So I waited and waited. Then I emailed them and asked why it was taking so long to process. They got back to me that they needed to get a new shipment of panels. So I waited some more. Then I received and email telling me that they had discontinued the bifacial panel and asked if I would take a single face 220watt panel as a replacement. I am not interested in having an inferior panel with less wattage output. Not to mention, this other 220watt single face panel also no longer exists on their website.

They literally have nothing to replace their product with. I asked if I could return both panels and get my money back, to go elsewhere and find a panel that can output close to 500watts and they are refusing to budge based on a 30-day return period.

This is a multi-billion dollar company and they have no product support. Needless to say, I cannot recommend Ecoflow moving forward and will seek to purchase from other manufacturers of solar and power. Ecoflow equals poor quality customer care.

Spring 2026 I bought an ecoflow balcony power station with 6 panels & 3 STREAM power stations. After installation one POWER station had an issue. The ecoflow support was very much dedicated to help and ecoflow easily committed to replace it with a brand new one. Since a couple of weeks all is working properly. That's what I really like, products that are simply working properly and if not, you get help to get it working properly. Awesome. Strong recommendation.

Great customer service. And great product overall. We are leaving to africa with a Toyota LandCruiser LC100, and made the choice to have the Delta 3 MAX. And we are super happy with it...

Thank you!! Gigi and Paulina from Beyond Comfort.

I have the EcoFlow delta pro. The unit quit working properly and I am living off grid. I explained to EcoFlow that without power I cannot charge my devices or power my Starlink, which leaves me without Wi-Fi or cell service. I keep getting the runaround from EcoFlow‘s Customer Support. It takes me between four and five hours to get back to cell service. Charge my phone and contact EcoFlow customer support. When I speak with them, they will not allow me to speak with a supervisor or manager. I keep getting emails that ask for more photos more questions and videos. I have submitted an answered all their questions, videos, etc. Besides the 4 to 5 hours it takes me to get from off grid back to cell service and Wi-Fi and charge my phone and back home. It is also the gas involved. EcoFlow is giving me the runaround. All I get is emails from them and then the worst part is they said because I did not respond within five days they closed my case. I explained I am living off grid with no power and cannot make daily trips due to the gas in the distance. I have animals. I cannot leave locked inside as I cannot cool my home and it’s been extremely hot. I was told by Customer Support over the phone that due to my off grid situation once they reviewed the emails with the answered questions. Photos and video. A unit would be sent out to me immediately. Once I received the new unit I would send back the faulty unit. That never happened and it’s been two weeks. EcoFlow Support has been one of the worst I’ve dealt with and I highly would recommend anybody considering their product purchasing from a different company. EcoFlow’s phone support sounds promising, but I believe it is a bait and switch because once it gets to the next department, their support is nonexistent. EcoFlow is not a trustworthy company and their pricing is very expensive.
Buyer beware.

I am giving Ecoflow this rating not because of their product but because of their abysmal technical support. Their phone-in contact center does not provide technical support, this must all be done via email. The net result is that it takes several days to resolve a problem because emails go backward and forwards with 24 hours between responses. To add insult to injury, the responses from their technical team are vague and unhelpful, lacking actual steps to take. We installed a full home backup system that didn't cut over during the grid failure, so it was as useful as a rat-flavored lollipop. Great after spending around $10,000 for a system that did not work as advertised. If just one person reads this and doesn't buy from them, I'll be happy, because they do not deserve your hard earned money. I will say though, that I used to be a big fan - their technical support used to be given very competently over the phone, but this has changed over the last year. The product referenced here is the Smart Panel 2 combined with Delta Pro Ultra, so you are aware.

I am writing to share my outstanding experience with EcoFlow. I recently purchased the EcoFlow DELTA 3 Class, and I am thoroughly impressed with the company.
Their products are far superior to anything else I have used for energy banks, and their app is truly five star. The reliability and performance of their system have exceeded all my expectations.
I highly recommend EcoFlow to anyone in need of dependable power solutions.
Sincerely, mr shingler

The delta 2 max has been amazing, the product is genius. My experience with customer services has been productive. They responded efficiently and offered me a helpful solution. I will be using them again and still currently am. My situation is quite unique and they worked to suit me to find a solution. I would and do recommend Ecoflow to others. Customer services was satisfactory as well
