EF ECOFLOW Solar Generator 120V/3.6KWh DELTA Pro with 400W Portable Solar Panel, 23% High Efficiency, 5 AC Outlets, 3600W Portable Power Station for Home Backup Outdoors Camping RV Emergency

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. 💪🔋

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.

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’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 absolutely love these EcoFlow units. This Delta Pro Extra Battery is no exception. I own several EcoFlow products, and they’ve consistently been at the top of my list compared to other brands I’ve tried. This extra battery connects to the Delta Pro easily. It is heavy, so you may want someone to help you move it, but the wheels make rolling it into place simple. It comes with a very solid, thick connection cable that attaches securely to the Delta Pro. The extra battery has given me a huge boost in runtime. We use our Delta Pro as part of a backup system with a transfer switch, and adding this battery has made everything work even better—especially during outages and peak-hour usage. We already have solar on the house, so pairing that with EcoFlow has actually helped us reverse our electric bill. Pretty amazing. One of my favorite things about EcoFlow is their app. It’s smart, reliable, and shows exactly how long you have left on your battery, how long it will take to charge, and the wattage each device is pulling. I also love that you can use third-party smart plugs in the EcoFlow app; I use Tapo plugs and they work great. You can set timers and manage everything right from your phone. Charging flexibility is another big win. Whether I plug it into a standard outlet or charge it through solar, it’s quick and efficient. I personally charge mine at a lower wattage, but it’s capable of charging much faster if needed. EcoFlow always has great deals, excellent customer support, and a dependable honor system. This extra battery was a must-have add-on for my home setup, and I’m thrilled with how much more power and freedom it gives me. A fantastic upgrade.

I purchased 2 of these generators this year to take advantage of the tax credits that are (supposedly) expiring at the end of 2025 - and to protect my home in the event of a power outage. While there are a myriad of benefits to these units, there are a few things that I would have liked to have seen either done differently or added to the units. First and foremost, they simply have too many different variations of the same units available here on Amazon and elsewhere (including their own website). There's the Delta Pro, the Delta Pro 2, the Delta 2 Max, the Delta Pro 3, the Delta Pro Extra Battery, the Delta Pro Ultra, the Portable Power Station, the Power Station 6144, the Solar Generator Package - and the list goes on and on from there. I'm just an average guy who doesn't deal with Amps, Watts, Volts, and such on a regular basis... so much of the description of these units is lost on me. And which one to pick was more of a guess than a knowledgeable "choice". Next, if you purchase 2 of these units, YOU *MUST* PURCHASE THE DOUBLE VOLTAGE HUB (unless, of course, it happens to be included in your package deal). The double-voltage hub is just fine and easy to hook up - HOWEVER, it has an "on/off" switch that, when hooked up to be the battery backup system for when power goes off in my home, it precludes (or, more simply put, it STOPS) the unit from *automatically* taking over and pumping power through my house. "Why is that?" you ask?? Well, I'm glad you asked... because you must leave the double-voltage hub in the "off" position or, it will be sending power to your automatic transfer switch and it will take over for the circuits you want it to "back up" in case of an outage. In other words, when power goes out, you must manually go and click the double-voltage to the "on" position for the power in the batteries to actually do what they're designed to do. I know, I know, it's not that big of a deal to walk into the garage and click the on/off switch. However, I snow-bird back and forth to Wisconsin from Florida and I didn't want anything manual to swap to the backup system. I wanted it to be *automatic* - and it's not. Beyond that, these units are awesome. I connect to them through blue-tooth on my phone and I can see any power coming into the unit, any power going out of the unit, the temperature, how long the unit will run until empty without recharging, and on and on... These are great units - they are just difficult to know what to buy and the on/off switch on the double-voltage hub is, in my humble opinion, a stupid feature. They should've had a "standby" feature that, when power was no longer in the main circuit panel, would automatically trip itself "on" and it would solve everything. That's the only reason I dropped it down to 4 stars... These are really great generators, overall.

The EcoFlow DELTA Pro delivers serious, dependable power whether you’re off grid with the RV or dealing with a home outage. With 3600Wh and multiple 120V outlets, it easily handles heavy-draw devices that most portable units struggle with. The fast 2.7-hour recharge is a lifesaver—you can top it off quickly before a trip or during short power windows at home. For RV boondocking, it runs essentials without breaking a sweat and gives you true flexibility without firing up a generator. At home, it’s strong enough to keep critical appliances running when the power goes out. The LiFePO4 battery chemistry means long life, safety, and stable performance. Solid build, plenty of power, and zero hassle. A serious upgrade if you need reliable off-grid capability and emergency backup in one 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 ...
