7.2kWh Portable Power Station: DELTA Pro with Extra Battery, 120V Lifepo4 Battery Backup with Expandable Capacity, Solar Generator for Home Use, Power Outage, Camping, RV, Emergencies

We’ve been using the EF ECOFLOW Portable Power Station 3600Wh DELTA Pro to run our heat press at vendor markets, and this thing is an absolute beast. It handles the load with zero issues. No voltage drops, no struggling, just smooth and consistent power the entire time. The 3600W output is more than enough for our setup, and having five 120V AC outlets makes it super easy to plug in everything we need without juggling extension cords. It fires up fast, runs quiet, and gives us total peace of mind when we’re on-site and making products live. Battery life is impressive. We can run multiple presses without constantly stressing about recharge time, and the build quality feels solid and professional. It’s clearly designed for real work, not just camping or emergency backup. If you do markets, pop-ups, mobile businesses, or anything that needs serious, reliable power without a generator, this is 100% worth it. One of the best investments we’ve made for our business. 💪🔋

I bought this so I can run my home oxygen concentrator when the power goes out. Yes it is heavy to move around, but being able to have it inside is a plus. As soon as it arrived, I charged it up, did the firmware update and then I put my concentrator on it with just the generator, no additional battery. I had 10 hours 47 minutes available. That's awesome. Times that by 2 and that's the power I have before zero. A good set of solar panels will keep this running at peak. Cloudy days or night, I have a generator to recharge. Total peace of mind knowing between this and my tanks I will not run out of oxygen. I wish I could give this 5 more stars. I love this product.

I’m very impressed with the EcoFlow DELTA 3 portable power station. It delivers fast charging, reliable performance, and plenty of power for a variety of needs — whether it’s for home backup, outdoor adventures, or emergency situations. With its high-capacity battery and strong 1800 W output (3600 W surge), it can run most household appliances and electronics without trouble.  One of the standout features is how quickly it charges using multiple input options — AC, solar, or car — giving flexibility no matter where you are.  The unit also includes multiple output ports, so you can power several devices at once, from phones and laptops to refrigerators and fans.  The build quality feels solid, and the battery uses durable LiFePO₄ cells designed for long life, meaning this power station should stay dependable for years.  Overall, it’s a well-rounded and powerful portable energy solution that I’d definitely recommend for anyone needing reliable off-grid or backup power.

I would like to start out with the app which crosses over into the feature set. I'm an Android user and I find that most companies will focus more efforts on their iOS app; Android being "the red headed step child". That is NOT the case with Ecoflow. I can't speak to the iOS app, but their Android app is absolutely top notch. I would go so far as to say it's in the top 5 apps, as far as user experience goes, that I've ever used. Getting the device connected to WiFi, upgrading the firmware, and getting it set up is extremely intuitive, never had any issues or errors which are typical with other devices (not just power generators, but all devices that connect to WiFi). The intelligence to include a lower charge shut off and an upper charge shutoff tells me that they really considered the lifecycle of your investment. Additionally, you can limit the amount of wattage the devices charge at for their various charging methods, that's just going above and beyond in my opinion. You don't have to worry about tripping any breakers or anything like that. As far as hardware goes, they're pretty solid devices. From the rugged exterior and cables down to the quality of the LCD screen it's all very well built. I LOVE that they had the forethought to include the collabsable handle and wheels because these suckers are HEAVY. On that note, I wish they put hand holds in the box that they come in. Carrying something that heavy and awkwardly sized to get it in the house and unboxed is a bit of a pain. I aggravated a knee injury in the process; although I'm partly to blame for that one. Simple perforations in the sides of the box for the hand holds like many other manufacturers of large gear would go a long way. I'll close with their customer service. I happened to catch this on a bundle + a deal that included a grounding module. Apparently, during checkout with Amazon, there was a checkbox that I didn't check to opt in to this deal. When I contacted customer service, they pointed this out, but still asked me for my shipping address and sent me the grounding unit at no cost to me! Additionally, I've been contacted by them since receiving the bundle to make sure that I was all set and addressed the single question I had. I really ask that anyone reading this part goes back to the beginning of this paragraph and reads it again. When is the last time you got what you would consider even "adequate" customer service? When was the last time you got "good" or even "excellent" customer service? This is one of the best customer service experiences I've ever had if not THE best. I want to emphasize that they weren't annoying about it either. I simply had a voicemail one day from them stating that they were just checking in to see if everything was working OK and if I had any questions to give them a call back. A single voicemail. No emails, no multiple phone calls, just a voicemail. Point is, I wasn't being harassed. They just wanted to make sure that I was set with my investment. Delta Pro 9/10 EcoFlow App 10/10 EcoFlow Company 11/10 I'm docking the Delta Pro a point for 2 reasons (and this really applies to the extended batteries as well). One being they could've put a little more thought into the cumbersome nature of moving the box around, simple perforated hand holds in the outer carboard box would've rectified this. Also to that point, it would be nice to have a less conspicuous box. Anyone within viewing range could've easily looked up what EcoFlow offers and known these boxes were worth stealing. The second reason I dock a point is that I'd like included is some dust & water resistant covers for USB and AC outlets. To charge the device, there's a door that flips up (not spring loaded) so that's at least a little protected. These are going to be in my basement and there's going to be dust. I know they offer a pretty expensive cover for this reason but some removable rubber plugs I think is minimum as the cost of them justifies a little more forethought for protection of the power outputs. I have already recommended them to anyone I've talked with looking for a power station, generator, or reliable battery backup for important electronics. Just this past week a tornado went through our neighborhood and someone was looking for backup suggestions because their sump pump went out and their basement flooded. I recommended the Delta 2 (the Delta Pro is a bit overkill for a sump pump).

This is our second ECOFLOW product we've owned. Our first was a Delta 2. It served us well, but ultimately it was too small. That's where this one comes into play. We chose this unit because of it's storage capacity, power output, ease of attachment with accessories and ECOFLOW's reputation. We could have gone a different route, such as a different brand or simply building my own solution, but ultimately this was the better solution for us. ECOFLOW is the solution to go with if you need a solution that works out of the box. We'll be using this unit with our 1400 W of solar panels we've assembled plus the Alternator Charger we bought to work with the previous unit. ECOFLOW has a good reputation regarding quality. Our previous unit never had any issues and I don't anticipate this one having any issues. One word of note - It's heavy. It rolls on built-in wheels and has a built-in handle to help get it around.

I like this seems to work really well. I like that. It has the Bluetooth connection to your phone and it’s super easy to charge. I have not used the solar panels yet but I like that they are there in case I need them. I did plug in a 1500 W heater and the time it said it would run it but it’s two hours that was a bit surprising to me I thought it would last longer than that but sure it’s just a factor of the size of the battery. It’s a bit heavy, but that also expected based on the size of the battery. The handle to move it around is at the very bottom and while it’s in a great position when you are rolling it it’s a little hard to get to and get out other than that. I have no complaints about this machine. I really like it.

Excellent portable power solution for camping, emergencies, or on-site work. Battery management is solid, with decent recharging options and a responsive display. It’s a bit heavy, but that’s expected for the capacity. Overall, a dependable, versatile unit.

After finally having a chance to use this for powering my travel trailer, I am VERY disappointed in its operation. Plugging in to the 30 amp connection and powering on the 15k air conditioner and turning on a handful of various devices, after 10 minutes or so, the device shuts down with a 110 error code. It resets after 20-30 seconds and powers back on. It happens again after a similar time (I'm not running hair dryers, just usual electric devices used in every day life.). Now, every time, the air conditioner compressor has been 'on' after the obligatory initial time delay, so it's not the compressor kicking on that's tripping it. Cool air has been flowing from the vents. The AC is on AUTOMATIC, so it would have cycled off and the fan would shut down before turning back on. I had me Ecoflow app open and noticed it was putting out appx 1800 watts when it resets. I contacted Ecoflow customer service and opened a trouble ticket. The customer service representative assured me the unit would be replaced once I provided some information to verify the productto be defective. They asked what firmware was installed. I had updated the firmware already, hoping this would clear up the issue before needing to call tech support. They said to try a hard reset on the unit and gave me instructions on how to do this. I did so but the problem persisted. The next day I get an email from the technician Eric: " Thank you for reaching out. It seems that the surge power required by your air conditioner might be too high. We recommend adding a soft starter to manage the power surge effectively.". Obviously, this person never read the description I painstakingly provided to the agent. I emailed Eric that my air conditioner ALREADY had an Easy Start. The next day, Eric emailed me requesting a video showing the unit failing and to use some different devices to see if the unit would fail. I did so and sent it in, along with screenshot of the power input/output. I have a smaller secondary AC (620 watts), which I used instead of the main AC. I needed additional devices running to get to the so I plugged in a counter top oven and turned on the microwave. Took pictures and movies showing it failing again. Again, a day later I get an email saying:"Delta Pro is limited to 3600W. Your appliances has exceeded this limit, which triggers an overload. It's important to note that the Delta Pro can operate for 4-5 minutes because the power demand is gradually increasing, but it will go into overload once the 3600W threshold is surpassed.". One problem, I have an additional Ecoflow battery, which gives me 7200W of avaliable capacity. ". So, I setup ANOTHER test, keeping total watts limited under all their described limits. I take another video and screen captures and send it in. A DAY LATER, I receive this from Eric:"We are sorry about the issue you encountered. Thank you for reaching out. The output power on the left is limited to 2400W. We recommend trying the output interface on the right. If the connector is not suitable, you may need to purchase a compatible adapter connector from a third-party supplier.". Yes, the screenshot shows 2800watts input, BUT IT'S TOTAL INPUT. I have 1200watts of solar, and at that time, it was producing nearly 700watts, which brings the AC input to 2100watts, below their requested threshold. I get the distinct impression Ecoflow is trying REAL HARD, to renig on the warranty for this device. Update - I realized the technician thought I was plugging into the 15amp 110v plug on the left, but if you look at the photos and videos you can clearly see I am using the 30 amp 'RV' plug on the right. After multiple emails and phone calls to the 800 support line, they have finally come to the conclusion the unit is defective. Unfortunately for me, it took so long to get Ecoflow to agree it was bad, it was outside the 30day new replacement period. They will send a refurbished unit ...
