Launching on June 24th, 2024, the EcoFlow’s newest solar generator (portable power station) is a workhorse. In fact, the EcoFlow designers were inspired by a world where horsepower reigns supreme. Taking cues from sleek sports cars, the EcoFlow Delta Pro 3 (DP3) is infused with that same DNA from its beautiful lines to an LED display that evokes the gauge cluster of fast cars.
Skipping a Generation
The previous generation was called the Delta Pro (DP), so what happened to the Delta Pro 2 (DP2)? Some have speculated that the Delta Pro Ultra (DPU, the big brother of the DP and DP3) was internally called the DP2 and later renamed as the Delta Pro Ultra. But according to the DP3 team at EcoFlow, they wanted to align the DP3 with upcoming 3rd generation batteries.
Most of their current lineup is on generation 2, such as the Delta 2 series, River 2 series, or the Wave 2. So just like Apple skipped the iPhone 9, EcoFlow skipped DP2 and went straight to DP3. During half of the beta testing period, the DP3 was internally referred to as the DP2, but now renamed, the Delta Pro 2 does not exist.
Changes From the Previous Generation
While the original Delta Pro touted 3,600 watts of 120v AC output, the DP3 ups that figure to a massive 4,000w 120v AC output (surge up to 8,000w or handle up to 6,000w sustained with EcoFlow’s X-Boost feature, which lowers the voltage to allow higher wattage appliances to run).
Even more impressively, the DP3 now includes both 120v and 240v in the same unit! No more need for the EcoFlow’s Double Voltage Hub and two separate Delta Pros combined to produce 240v. On the DP3, you can choose either 120v (up to 30 amps) or 240v (up to 16.7a). Unfortunately, it’s one or the other. As soon as you press the “on” button for either the 120v side or the 240v, it shuts off the other side.
Another major change is the fan noise. Whereas many have complained about the noisy fans of the Delta Pro, which some have likened to a leaf blower, datacenter fans, or standing next to a space shuttle launch, the DP3 features X-Quiet technology. That means at 2,000 watts, the DP3 is whisper quiet…only 30 db (a soft whisper level).
Gone are extra battery expansions that are the same size as the main unit. The old Delta Pro’s extra batteries doubled the footprint and were not stackable. But the new DP3 extra batteries are not only sleek, complete with two side handles that make for easy one-person transport, but also space-saving and stackable. You can stack up to two extra batteries right on top of the main DP3’s top face.
Oh, and they now come with 90-degree battery cables, so you can push the entire DP3 stack right up against the wall for maximum space saving.
The DP3 can also now serve as a 10ms UPS (uninterruptible power supply), not a slower 30ms EPS (emergency power supply). So if you have any equipment that simply must stay on, like a computer, plugging it to a DP3 that is attached to a wall outlet allows for near instant switchover. I tested it on an all-in-one PC computer and did not experience any loss of power or a flickering screen, but note that this is not a 0ms UPS, so if you have an extremely sensitive setup like a datacenter, keep that in mind.
Solar input capacity has also improved from 1,600w on the old Delta Pro to a whooping 2,600w input (1,000w on the low voltage input, 11-60v at 20a max, and 1,600w on the high voltage input, 30-150v at 15a max) on the DP3. Just be careful not to overload the voltages (use VOC, not VMP), or it can permanently damage the battery.
Specs
Design
Hands down, the new DP3 design is more modern than the old Delta Pro. It’s sleeker, but the dimensions are slightly changed. The DP3 is slightly wider, shorter, and longer.
The port covers are cleverly designed to flip out, then fully retract back into the DP3 housing itself. That makes for a neat setup. When not in use, you can leave the ports covered for dust protection. On the side, the sliding doors are even magnetic.
The entire housing is treated with UV resistant coating to hold up better to prolonged outdoor use as well.
However, the most improved design award goes to the extra batteries, expansion packs that you can attach to double or triple your capacity. Go from 4,096 wh (main DP3 unit alone) to 8,192 wh (with 1 extra battery) or 12,288 wh (with 2 extra batteries).
You can even purchase three stacks of DP3s, each with 2 extra batteries. That expands your total battery capacity to 36,864 wh if you connect all three stacks to the EcoFlow Smart Home Panel 2 (SHP2), which is essentially a subpanel for your home.
EcoFlow actually claims expandability to 48 kwh, which is achieved in conjunction with their also soon-to-launch Dual Fuel 4,000w Smart Generator.
The main DP3 unit features robust, built-in wheels and an integrated telescoping metal handle for easy transport. Like for any typical suitcase, just press the button on the handle, retract the handle, and roll to your heart’s content. It easily handles typical backyard terrain with ease. You probably don’t want to go hiking or traverse over extremely steep or treacherous terrain, but the wheels and handles make the 113 lbs weight of the main DP3 feel much lighter.
There are also nice padded sleeves on additional side handles built directly into the DP3’s housing. Same with the extra batteries—they feature the same padded handles.
Unfortunately, the extra batteries lost the wheels of the original Delta Pro, but the new batteries are significantly smaller than before. The original Delta Pro’s extra batteries were approximately the same size as the main DP itself and non-stackable, but the DP3 extra batteries are half the size and stackable. With two handles built into the side of the DP3 extra battery, grabbing them and moving them is easy. Each extra battery weighs 72.75 lbs (33 kg), so it isn’t light, but the way the weight is distributed and with the handles, it feels exceptionally well balanced and easy to move.
With 90-degree extra battery connection cables, a full DP3 stack with 2 extra batteries is surprisingly compact. You could easily push it against the wall or into a corner. While it will be too heavy to roll an entire stack at once, moving the extra batteries one at a time poses no big strain.
The geometric pattern printed on the top face gives the entire unit extra flair, a certain je ne sais quoi. Unfortunately, my test units came damaged by the shipping company, which clawed through the beautiful pattern and left dozens of deep gouges. Luckily, it did not affect battery operation whatsoever.
Ventilation ports are well placed unobtrusively as well. They blend beautifully with the overall design. Overall, the designers truly thought through the look, giving the DP3 an incredible aesthetic appeal. Though design is subjective, I would argue the DP3 is currently the best-looking portable power station on the market.
Use Cases
Design may be sexy, but for most, function comes before form. Here, the DP3 is no slouch. Its massive capacity (4,096wh per battery), massive output (4,000w), and massive solar input (2,600w) make it ideal for virtually any scenario.
Throw in a 2.5 ton HVAC, or two space heaters on full blast, or various power tools with huge in-rush currents, and the DP3 doesn’t miss a beat.
Incredibly, the DP3 even included both 120v and 240v ports on the SAME unit. That means you don’t need to buy a second DP3 (like you did with a second original Delta Pro) to get 240v. Just keep in mind, 4,000w / 240v = 16.7a, so you can’t go above that without overloading the circuit. I tried a 20-year old 240v clothes dryer, which overpowered the DP3. The amps were too much.
The solution? Get the EcoFlow 50a Voltage Hub accessory, combined with a second DP3. That increases the capability to 8,000w and 33.33a at 240v.
If you just need to power a 30a RV, then a single DP3 is enough, as it has a built-in TT-30 30a outlet on the side.
I typically use the DP3 for home backup or even grid power replacement. With rolling blackouts happening more and more, the DP3 has allowed me to power the vast majority of my home’s appliances: fridge/freezer, computers, lights, water pumps, power tools, TVs, microwaves, space heaters, heat guns, and more.
If your house has an inlet box or something like the EcoFlow Smart Home Panel 2 (unfortunately, the DP3 is incompatible with the Smart Home Panel 1), then plugging in the DP3 and extra batteries will energize all the outlets in your home, so you don’t have to run long extension cables to various rooms.
With rising electricity rates, being able to charge the DP3 with solar means free energy to reduce my utility bill. I was able to connect over 2,000w of solar (it allows up to 2,600w), which let me recharge quickly. For even faster charging, you can add AC wall charging for an additional 1,800w. With AC charging alone, the DP3 can charge up to 80% in 50 minutes—now that’s fast.
I’ve also used the DP3 to power my 30a RV. With an older home, I don’t have 30a hookups, but the DP3 features a TT-30 30a outlet. At first, when I tested it, the DP3 did not power my RV, but I quickly realized that was user error. I was using an RV surge protector, which detected an open ground, so it did not allow power to be sent into my RV. To fix the problem, all I needed to do was toggle on the GFCI/RCD setting in the EcoFlow app, which essentially tricks my surge protector into thinking there is a ground, thereby allowing the electricity to flow. It worked flawlessly after that.
Similarly, charging an EV (electric vehicle) like a Tesla requires a ground, so you’ll also need to toggle on the GFCI/RCD setting in the EcoFlow app. So yes, EV charging also works with the DP3.
In fact, you can even drive up to a level 2 electric charging station and use the J1772 plug meant for cars like Chevy Volts to charge the DP3 itself. There’s a dedicated port to accept EV station charging plugs (but J1772 style, not Tesla’s NACS style connector…you’ll need an additional adapter for that). To enable this charging feature, you’ll need to get the EcoFlow EV X-Stream Adaptor.
Another use case I’m planning for the DP3 is off-grid living. On a rural piece of land with no electrical hookups, the DP3 is a worthy alternative to its big brother, the Delta Pro Ultra (the DPU has higher specs but is physically bigger and more expensive) or the EcoFlow Power Kit (up to 15 kwh). The DP3 is meant to be more portable, while the DPU is intended to be relatively stationary, despite the DPU’s roller wheels. The Power Kit is completely stationary meant for permanent installation into an RV or off-grid cabin.
Whether you plan to power a hunting shed, a yurt, a glamping tent or dome, or some other structure, 12 kwh and some decent solar should net you enough power indefinitely. Unless you’re planning on running extremely high-powered appliances for long, such as space heaters or air conditioners, 12 kwh is plenty to power most other needs: laptop use, phone charging, electrical cooking, lights, internet, etc.
AC Power Output
Four 120v AC ports (NEMA 5-20R, 20 amps) allow for plenty of appliances. You can also increase outlets with a surge protector strip. On the 240v AC side, a NEMA 6-20R port is good for a 2.5 ton central AC unit, water pump, or clothes dryer (as long as you don’t go over 16.7 amps), and the L14-30R port allows you to connect to an inlet box, either 120v or 240v, to power your entire home’s circuits.
A NEMA TT-30 outlet on the side allows 120v at 30a, perfect for many RVs, camper vans, or trailers. It can even power air conditioners, microwaves, and high dryers—all high-powered appliances.
If you need to power a 50a RV, then you’ll need the 50a Voltage Hub accessory (purchased separately) and a second DP3. (Note: Apparently, this point might be under contention. There was an official EcoFlow video posted on their YouTube channel claiming that the hub + 2 DP3s could power a 50a RV, but I spoke to the DP3 team directly and they said that was a mistake in the video.
But I’m confused because 33.33a at 240v single phase is the same as 33.33a at 120v split phase, which is how 50a in an RV works with two legs of 50a, 120v each. You wouldn’t get the full 50a service, but a reduced 33.33a service. In any case, the hub currently can only enable 8,000w at 33.33a, 240v, but not 50a, 120v. They may enable the latter with a future firmware update though.)
DC Power Output
DC charging is also quite capable. While the 12v cigarette lighter port has been removed (it’s available on the Delta Pro), a host of other DC outputs are available. My favorite are the dual USB-C PD (power delivery) ports, which can give 100w of power each. There are also fast-charging USB-A ports at 5a, 18w each.
Additionally, a DC5521 port (5a max) allows for devices like WiFi routers or security cameras. The included Anderson port (30a max) is perfect for low-voltage DC devices lighting or small kitchen appliances. There is also a communication port to attach an RJ45 cable for remote communication using a separate remote control monitor (sold separately).
Charging
A 15a AC input allows for incredibly fast AC charging up to 1,800w, which can be combined simultaneously with DC solar charging (another 2,600w) for a total of 4,400 w charging. The app allows you to choose a specific wattage for AC charging speed if you wish to charge slower, which can help prolong the battery’s lifespan. However, I honestly don’t even worry about that, since the LFP (lithium iron phosphate) battery chemistry is rated for 80% capacity after 4,000 full cycles. To put that in perspective, that means you could charge and discharge the battery (0-100%) every day for 10 years straight, and you would still have 80% left of its 4,096 wh capacity per battery.
Using the EcoFlow X-Stream EV charging adaptor (purchased separately), you can even enable charging at EV charging stations. Simply take the Type 1 SAE J1772 connector found at most EV charging stations (but not Tesla Superchargers, which use the NACS connector), connect it to the X-Stream adaptor, and plug it into the DP3’s side port for level 2 charging up to 4,000w.
Solar charging includes two ports: low voltage (11-60v, 20a max) and high voltage (30-150v, 15a max). The low voltage port allows for up to 1,000w solar input, while the high voltage allows for 1,600w solar input. Together, they can pull in 2,600w, which is in addition to the 1,800w AC charging.
With so many ways to charge at such high speeds, this thing will be replenished in no time. Given each battery’s massive 4,096 wh capacity, that’s a notable feat. With the extra batteries connected, they will also simultaneously be charged.
Fan Noise Levels
Given how powerful the DP3 is, capable of taking in massive charge and outputting insane power, you may worry about how loud the thing is. Never fear, X-Quiet technology is here. You won’t (hardly) hear a thing. At 2,000w (half its max sustained output), the DP3 fans barely make a sound, producing a whisper-quiet 30 decibels only.
This is a huge improvement to the original Delta Pro, whose fans were noisy according to many users. However, some users disagreed and reported the fan noise wasn’t really noticeable even with a decent load or charge rate. Regardless, the improved DP3 takes things up (or rather, down) a notch—to truly whisper quiet operation even while running a significant load.
You could take an exam or easily watch quiet scenes in a movie with the DP3 running and wouldn’t be bothered. The engineers did a remarkable job at quieting the fans. It’s not just marketing speak. This thing roars with monstrous power, but its fans barely purr.
Backwards/Forward Compatibility
A recent firmware update allowed the old Delta Pro extra batteries to become compatible with the DP3. You can even plug in one old DP extra battery and one new DP3 extra battery into the same DP3 main unit and have them all work together.
However, the older Delta Pro main unit is NOT compatible with the DP3. The DP3 is also NOT compatible with the Smart Home Panel 1 (SHP1), but it is compatible with the Smart Home Panel 2 (SHP2). Perhaps a future firmware update can enable wider compatibility, but who knows. No guarantees.
Standout Features
Rather than focusing on the upgraded power and input specs here, which to be clear are impressive, I’m going to describe special features I loved.
- 120v and 240v in a single unit! Finally! This is a game-changer because you no longer need two Delta Pro units and a Double Voltage Hub (more than doubling your cost) to achieve 240v. However, if you want even more power of 8,000w at 33.33a and 240v, the 50a Voltage Hub and a second DP3 are required (Note: There was an official EcoFlow video posted on their YouTube channel claiming that the hub + 2 DP3s could power a 50a RV, but I spoke to the DP3 team directly and they said that was a mistake in the video. So far, the hub can only produce 8,000w at 33.33a, 240v, but not 50a, 120v. They may enable the latter with a future firmware update though).
- No more open ground issues. The DP3’s GFCI/RCD support enables usage of things like an RV surge protector or EV (electric vehicle) charging without a bonded neutral plug, such as the EcoFlow Grounding Adaptor
- Dramatically smaller, stackable expansion batteries with 90-degree connection cables for major space-savings
- The NEMA TT-30R 30a outlet is perfect for 30a RVs. While some other portable power stations offer this too, it’s not always a standard feature. Having it is perfect for boondocking (RV camping without electrical hookups).
- Near noiselessness. Even though X-Quiet technology is whisper quiet, I want to shout about it from the rooftops. It’s that quiet.
EcoFlow App Features
As with any smart power station, the accompanying EcoFlow app enables multiple additional features and firmware updates. Some users are uncomfortable using a phone app, which is fine. It’s not actually needed for basic operation, since the DP3 is plug and play. But if you wish to enable advanced features or update the firmware, which not only fixes bugs but also occasionally adds new features, then the app is essential.
The app allows for easy monitoring of power usage and input wattage. You can tell at a glance how much power is being used at any given moment. It even breaks the readings down by specific ports, such as AC low voltage (120v), AC high voltage (240v), USB-C and USB-A ports, and 12V DC output. You can further see input readings from AC charging, solar low voltage input, solar high voltage input, and smart generator AC input (such as from the new EcoFlow Dual Fuel 4,000w Smart Generator or their older model).
The app is comprehensive yet intuitive and elegant. Despite the multiple settings, I did not get overwhelmed. Everything is laid out logically, so the learning curve is flat. Many settings even offer a little pop-up explanation to explain how they work.
For example, the “Backup Reserve” setting lets you decide what percentage you want the DP3 to charge up to using both AC and solar simultaneously. Anything higher than your defined setting will charge on solar only.
That setting allows you to charge at max speed to quickly top off your battery to your desired SOC (state of charge), which reduces your chances of being caught without enough power because you couldn’t recharge fast enough. After you reach your comfortable reserve level, the system switches over to solar only to help you reduce electrical utility costs. You can also turn off the setting completely if you desire.
Of course, you have the option to choose the maximum and minimum charge/discharge level too. Many recommend a 20-80% level to prolong your battery’s lifespan, but I personally like to set my parameters at 15-100% because I’m constantly using the DP3, so it doesn’t sit at 100% for long.
Another brilliant feature is the “Dynamic Energy-Saving Mode,” which you can toggle on the app. This allows you to save up to 30% energy if you are using devices that only need to be intermittently powered, such as a fridge whose compressor only turns on every so often. Or perhaps a water pump that doesn’t need to activate continuously, only when it needs to pump the water.
For such appliances, the “Dynamic Energy-Saving Mode” turns the DP3’s AC inverter on and off as needed, using its built-in capacitor to maintain voltage when the inverter is off. AC inverters are notorious energy draws, so it’s recommended to turn it off if you aren’t powering AC devices. The app allows you to set a timeout to automatically turn off the AC inverter if it’s not in use (or you can select to have it always on), but the Dynamic Energy-Saving Mode will turn the inverter on and off for you as needed for intermittent power use devices.
There is also an “Outport Port Memory” feature that lets the DP3 remember your ports’ on/off states, even when the DP3 is drained. After recharging, the DP3 automatically restores the last on/off state of your output ports. This is a nice touch, saving you from a little hassle.
The “X-Boost” feature allows you to power higher wattage devices beyond the DP3’s 4,000w AC specs. This is typically reserved for resistive heating appliances like space heaters, not sensitive electronics that require precise voltage levels. I typically don’t use this feature for fear of damaging electronics, but it’s there if you need an extra power boost. However, at 4,000w sustained capacity, I see few devices that would ever need X-Boost, which boosts the DP3’s ability up to 6,000w—I think? Need to confirm.
The “Charge & Discharge Order” option lets you choose between “Compatibility Mode” or “Priority Mode.”
“Compatibility Mode” allows you to connect your first generation Delta Pro extra batteries to the DP3 (yay backwards compatibility! Unfortunately, DP3 extra batteries are not compatible with the original Delta Pro nor the SHP1, at least not yet. No word if that compatibility is coming).
“Compatibility Mode” will charge or discharge batteries based on an algorithm that reads each battery’s voltage, charging the lowest voltage battery and discharging the highest voltage battery first.
However, “Priority Mode” is only available for DP3 extra batteries. This mode tells the DP3 to charge the main battery unit first and discharge it last, while charging up extra batteries last and discharging them first.
Why do that? Because an extra battery alone has no output ports, so it can’t power devices. You need the main DP3 unit, which contains the AC inverter and other critical features. If you decide to disconnect your extra batteries and find your main battery is depleted (or nearly depleted), then you’re out of luck. You would then have to wait for the main unit to recharge.
So having a setting that prioritizes charging the main battery first reduces the chances that you will be caught with a depleted (or nearly depleted) main battery, which is essential for operations.
Discharging the extra batteries first also runs down their battery cycles first, rather than the battery cycles of the main DP3 unit. Even though the lifespan of these LFP batteries are incredibly long (10+ years), if you do need to replace them, purchasing an extra battery is far cheaper by over $1,000 than buying the main unit.
Normal usage that first drains the cheaper, more expendable extra battery is ideal, preserving both the emergency readiness of the more expensive, essential main battery (by charging it first) and its the lifespan (by discharging it last).
Note: if you often run sustained high wattage outputs, it’s recommended to stick with “Compatibility Mode” to ensure more even discharging across a greater number of battery cells, which theoretically creates less heat buildup. You’d be spreading the load across 2-3 total batteries rather than a single extra battery (or two) alone. That would be healthier for battery longevity. After all, battery cycles aren’t the only thing that can reduce battery lifespans.
“Scheduled Tasks” (aka automations) are also available in the app. You can set various routines, such as turning on/off solar or AC inputs. That way, if you want to control what times (say 7am to 7pm) you want to allow solar to come in, and which solar port (LV vs. HV), you can.
The “Smart Generator Auto Start/Stop” feature lets you automatically start charging the DP3 via your generator once the battery reaches a predetermined charge level and stops once it reaches another predetermined level. This helps your battery stay topped off to your desired level without needing to babysit the DP3.
The “Night Care” function lets you choose what time your generator should automatically kick on to charge your DP3, provided it’s below 50% charge, so you can ensure your noisy generator doesn’t disturb people at night or break rules about campsite generator operation hours.
More basic functions include things like sharing the device monitoring/controls with invited family members or friends, turning the button beep on or off, adjusting the AC charging speed and DC car charging speeds/amps, auto-timing out the device after a certain period of inactivity, changing the screen brightness, switching between metric or imperial units, and updating firmware.
You can also turn on/off the outputs or inputs directly from the app with a touch of the digital power button.
There are also two choices of homepage styles. It’s truly personal preference how you want to see the data visualized.
Unlike other battery station apps, EcoFlow’s app elegantly presents the options in an easy-to-understand manner.
Room For Improvement
I wish the DP3 could offer 6,000w or more AC power. That would allow me to power 4 high-powered appliances simultaneously, such as space heaters that are 1,500w each. Foreseeably, I can imagine a scenario where people in my home are using a space heater, microwave, induction cooktop or electric water kettle, and hair dryer all at the same time. That would overload the DP3.
I also wish 120v and 240v could be operational simultaneously, not forcing me to choose between one or the other. While most appliances in my house are 120v, I do have a few 240v appliances. It’s a hassle to lose power to the 120v appliances when I want to power the 240v ones.
The 240v output also only offers 16.7a, which may not be enough for certain appliances. My 20-year old clothes dryer pulled more amps than that, so it instantly tripped the DP3. So I wish the 240v output could offer more than 16.7a, ideally 25a or higher.
It would be nice if the extra batteries had mini wheels and handles. The extra battery is not terribly difficult to move with the built-in handles, but wheels and handles would have been nice if they could be incorporated without compromising the battery’s stackability.
The extra battery connection cables are an extremely tight fit. It takes several minutes of painful wiggling (almost cut my hands more than once) to pry them loose from the connection ports. This might be seen as a positive by preventing accidental unplugging, but it is honestly far too tight. The EcoFlow engineers have acknowledged this, and supposedly, redesigned cables are in the works to allow for easier unplugging.
Better backwards compatibility. The extra battery connection cable heads look identical to the heads on the EcoFlow Power Kit battery cables, yet they are internally different. Currently, the DP3 main battery and extra batteries are not compatible with the EcoFlow Power Kit. Perhaps this will be enabled with a future firmware update.
The DP3 is also not compatible with the SHP1, which sucks for users who recently installed that at considerable cost. I wish the DP3 extra batteries were compatible with the original Delta Pro as well. Fortunately, the original Delta Pro extra batteries ARE compatible with the DP3 (even mixing and matching with 1 original DP extra battery and 1 DP3 extra battery attached to the same DP3 main unit).
Finally, I wish the DP3 could offer 50a service without needing a 50a Voltage Hub and second DP3. That would make it the ultimate battery station for 50a RVs.
Worth it to Buy or Upgrade?
If you need the larger capacity for power-hungry devices (like space heaters or air-conditioners), then the DP3 is perfect. Its expandability gives you plenty of capacity. Even a single unit at 4,096 wh is massive.
While the DP3 is by no means a small unit, it is relatively portable compared to options like the Delta Pro Ultra. So if you are looking for greater portability, the DP3 is it.
I probably would not take the DP3 camping unless I were planning a longer stay or somehow needed massive power. Smaller power stations like the EcoFlow Delta 2 or Delta 2 Max (or even smaller ones like the River 2 Pro) fit the bill better in those scenarios.
However, if you’re looking for emergency home backup power that can potentially last for days or hoping to massively reduce your electric bill, then the DP3 is the way to go.
It’s also ideal for RV/van boondocking (camping without hookups) or simply gaining assurance, since you can never trust that campsites will have reliable electrical hookups. Their systems are often old, outdated, deteriorated, broken, or unsafe.
For those looking to power their off-grid lifestyles, the DP3 is also worth the purchase. It’s easily wheelable from place to place on your land or setting up for one main spot to power your cabin, dome, yurt, outdoor kitchen, or other structure.
For in-field work at construction job sites, the DP3 can handle virtually anything thrown its way too. So it’s a huge convenience rather than running long, unwieldy extension cords or using smelly, loud gas generators.
Compared to the older Delta Pro, the DP3 is well worth the upgrade:
- far quieter fans
- 120/240v in one unit
- stackable, smaller extra batteries
- nearly doubled solar input
- more powerful specs (4,000w and 4,096 wh)
Space-age design, powerful specs and capacity, huge expandability, and countless quality-of-life features make the DP3 an exceptional portable power station. Although EcoFlow products are not cheap, the DP3’s versatility and quality make it well worth it. Combined with a 5-year warranty (or 7 years if you subscribe to EcoFlow and buy at launch), you can rest assured you will have power for years to come.
