Gunner’s take
Whole-Home Backup Tester
EcoFlow fit the DELTA Pro's inverter into a box one person can lift.
The DELTA 4 (3000) is rated 3,600 W continuous with a 7,200 W surge at 120 VA2, exactly what the DELTA Pro is rated for. It weighs 57.3 lb against 99 lbA7. That's 41.7 lb gone without giving up a watt of output.
What it gave up is battery, and the right to add any.
It holds 3,072 Wh against the DELTA Pro's 3,600 WhA1, and it has no extra-battery portA6. The DELTA Pro takes EcoFlow's expansion batteries and accepts 1,600 W of solar against 1,000 WA5. So the real question here is whether 3,072 Wh is the most you'll ever need.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
weight
So the weight pays only for 528 Wh of battery and a battery port. At 99 lb the DELTA Pro is a two-person lift on stairs, and reviews of the DELTA Pro line say its wheels like smooth floors and want a cart on rough groundB2, though that source may describe a sibling modelB0. At 57.3 lb the DELTA 4 (3000) goes into a hatchback with one person and two handles.
DELTA 4 (3000): 3,600 W continuous, 7,200 W surge at 120 VA2DELTA Pro: 3,600 W continuous, 7,200 W surge, 99 lbDELTA 4 (3000): 57.3 lb with a handle at each endA7
Why it mattersIf the box ever leaves the utility room, the DELTA 4 (3000) is the one you'll actually take.
The DELTA Pro adds a battery to the box you already own. The DELTA 4 (3000) answers a bigger need with a second station, which means a second set of outlets and a second charger to manage. That's fine for a fridge-and-lights outage plan. It's a dead end for a van build that gets bigger every season.
DELTA 4 (3000): no extra-battery port, sealed at 3,072 WhA6DELTA Pro: takes EcoFlow expansion batteriesVan Life Daily needs 4,685 Wh: the DELTA 4 (3000) is 2,074 Wh short, the DELTA Pro 1,625 Wh short
Why it mattersIf your plan is likely to grow, the DELTA Pro's port outweighs everything else on this page.
The differences sit at the two ends of the outage. When the grid drops, the DELTA 4 (3000) is rated to catch the load twice as fast, which a fussy desktop power supply cares about. When the grid comes back, its full charge rate fills a 15 A circuit on its ownA4, so on a kitchen circuit shared with a toaster I'd turn the rate down in the app before the storm.
8-Hour Blackout needs 1,645 Wh: the DELTA 4 (3000) finishes with 966 Wh left, the DELTA Pro with 1,415 WhDELTA 4 (3000): X-Stream wall charging up to 1,800 W, which at 120 V is 15 A, the full rating of a 15 A circuitA4Switchover: rated within 10 ms on the DELTA 4 (3000)A8, no worse than 20 ms on the DELTA Pro
Why it mattersFor one-night outages the 528 Wh isn't worth 41.7 lb; just set the charge rate before you need it.
The specific dimensions that decide these two units — everything else is a tie.
Growth Path
Selected because: The DELTA Pro takes extra batteries; the DELTA 4 (3000) has no port for one, so 3,072 Wh is its ceiling.
solar input
I'd only pick the DELTA Pro here if you'll grow. The DELTA 4 (3000) has no extra-battery portA6, so 3,072 Wh is the ceiling for as long as you own it. EcoFlow's expansion path for this generation belongs to the bigger DELTA 4A6, not this one. The DELTA Pro takes EcoFlow's extra batteries, and that's the one thing its weight buys that this box can't match.
Size it against your longest outage, not your average one. If the worst stretch you can picture fits inside 3,072 Wh, the sealed box is a complete system and the port is weight you'd carry for nothing. If you're already sketching a second battery, start with the one that has a port.
Portability & Form Factor
Selected because: 57.3 lb against 99 lb, a 41.7 lb gap that buys no extra output.
weight
The DELTA Pro rolls. The DELTA 4 (3000) gets carried. Reviews of the DELTA Pro line describe built-in wheels and a telescoping handle that are happiest on a smooth floorB2, though our researcher couldn't confirm which model that source testedB0. The DELTA 4 (3000) has a handle at each end, and EcoFlow sells a folding cart for it separatelyA7.
Basement stairs settle it. I carry gear down basement stairs for a living, and 99 lb is where I go find a second person. At 57.3 lb I'd do it alone, slowly. If the box will sit beside the panel and never move, the weight stops mattering after delivery day.
Your Life, Your Pick
Selected because: Both finish five of six runs; on Weekend Camping the DELTA Pro keeps 960 Wh to the DELTA 4 (3000)'s 511 Wh.
One blackout night is a draw. The 8-hour run needs 1,645 Wh, and both wake up with power to spare: 966 Wh left in the DELTA 4 (3000), 1,415 Wh in the DELTA Pro. A CPAP night, a remote workday and a tailgate fit easily in either.
Camping is the one run the DELTA Pro takes outright. A 2,100 Wh weekend leaves it 960 Wh against 511 Wh, and 511 Wh is the kind of margin a cold night eats into. Van Life Daily at 4,685 Wh beats both, and only the DELTA Pro can be grown to meet it.
What the Specs Don't Tell You
Selected because: Switchover is rated within 10 ms against no worse than 20 ms, and the two noise figures aren't published the same way.
rated cycles
On a grid drop, the newer box is quicker on paper. EcoFlow rates the DELTA 4 (3000) to switch over within 10 msA8 and the DELTA Pro at no worse than 20 ms, which is where picky desktop power supplies start to blink. Neither is a lab reading. EcoFlow's FAQ also says the DELTA 4 has no HID linkA8, the USB connection a UPS uses to tell a computer to shut itself down, so a desktop won't save its own work when the battery runs low.
The two noise figures aren't the same kind of number. EcoFlow rates the DELTA 4 (3000) at 40 dB or less up to 1,800 W and 50 dB or less at the full 3,600 WA8, a ceiling under load. Our record gives the DELTA Pro 60 dB without saying at what load, and a review of the DELTA Pro line heard a high-pitched whine above 2,000 WB4, possibly from a sibling modelB0. I wouldn't choose between them on noise until someone puts a meter beside both.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
DELTA 3000 Gen4
Both cover the night several times over: a CPAP uses 12% of the DELTA 4 (3000)'s usable battery and 10% of the DELTA Pro's. Noise can't split them either, because the two noise ratings aren't published on the same terms. Buy on weight or price.

Remote Workday
Full work day off-grid without power anxiety
Either unit
Both power your workstation all day without strain. At these utilization levels the real difference is USB-C for direct laptop charging — 140W on the DELTA 3000 Gen4 against 100W — which beats the inverter for convenience and wastes less energy.

Conclusion
November 4, 2026
Verdict: the DELTA 3000 Gen4
I'd buy the DELTA 4 (3000), unless you'll ever need more than 3,072 Wh. It matches the DELTA Pro's 3,600 W and 7,200 W surgeA2 in a box that weighs 57.3 lb against 99 lbA7, costs $200 less, and is rated for 6,000 cycles against 3,500. The DELTA Pro answers with 528 Wh more battery, 600 W more solar input and a port for extra batteries, which the DELTA 4 (3000) doesn't have at allA6. The DELTA 4 (3000) also ships in early DecemberA10, so anyone who needs power before then has one choice. I stop at 7 because every DELTA 4 figure is still EcoFlow's own and nobody has run one yetA0.
Today the DELTA Pro is $1,799, $100 under its typical $1,899. The verdict weighs typical prices, not today's. Prices checked 31 days ago.

Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
See the full weight table and data sourcing on our methodology page →Class ranking (the star rating)
Each unit's star score is a category ranking, not customer reviews — no buyer opinions feed it. We score every station on size-independent quality (value, output, portability, endurance, ports, warranty, and more), then percentile-rank it against the other units in its capacity class, so a class-leading compact unit and a class-leading whole-home unit can both earn 5★. Here, DELTA 3000 Gen4 rates 4.8/5 (86th percentile of 29 Large-class units), and DELTA Pro rates 3.7/5 (24th percentile of 22 Home Backup-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
Same Inverter, 41.7 lb Apart
The DELTA Pro weighs 99 lb, a two-person lift on stairs. The DELTA 4 (3000) is 57.3 lb with a handle at each end, and it runs the same 3,600 W.
DELTA Pro: 60dB Published
60dB is about as loud as a normal conversation. The DELTA 3000 Gen4 is rated 40dB, and the two are not the same kind of figure: the DELTA 3000 Gen4's is a MAXIMUM under heavy charge and discharge, while the DELTA Pro's is its maker's best case — so the real gap can only be wider than the numbers suggest: the DELTA 3000 Gen4's ceiling already sits below the DELTA Pro's floor. For most people, fan noise around 45dB and up is where sleep starts to suffer.
What You Buy Is All It Holds
The DELTA 4 (3000) is sealed at 3,072 Wh. The DELTA Pro starts at 3,600 Wh and takes EcoFlow's extra batteries. If your needs might grow, this card decides the page.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The DELTA 3000 Gen4 is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The DELTA Pro is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. If a computer with unsaved work is the thing being protected, the stated class is worth the attention; nothing here is a lab result.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The DELTA 3000 Gen4's figure is a maximum rather than a guarantee — it depends on registering the unit in the EcoFlow app, which adds two years to a three-year standard term.
Battery Lifespan in Real Years
The DELTA 3000 Gen4 is rated for 6,000 cycles vs 3,500. In real life: at daily use, that's 16.4 vs 9.6 years. At weekend use (twice a week), it's 58 vs 34 years. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.

Analyst note
The DELTA 3000 Gen4 is sealed at 3,072Wh, which is fine if that covers you. The DELTA Pro starts at 3,600Wh and can grow beyond it with EcoFlow expansion batteries — real headroom the DELTA 3000 Gen4 doesn't have if your needs climb toward partial-home backup.

EcoFlow DELTA 3000 Gen4
Nobody owns a DELTA 4 (3000) yet. It went on sale in the US on November 4 and ships in early December, so everything here comes from EcoFlow's spec table and FAQ plus our own arithmeticA0A10.
I'd want to pull a breaker on it. If I had one, I'd plug a desktop PC into it, kill the circuit in the middle of a file save and watch whether the screen even flickers. EcoFlow's 10 ms is a ratingA8, and nobody has timed it yet.

EcoFlow DELTA Pro
Reviewers treat the DELTA Pro as a home-backup workhorse. It has been called a long-standing standard for running a fridge, lights and a space heater through outagesB1, and one long-term review ran it as primary backup through months of overnight outagesB3.
The complaints are weight and fan whine. Wheels and a telescoping handle help on flat groundB2, and the fans whine under loads above 2,000 WB4. Our researcher found much of the coverage mixes the DELTA Pro up with the newer DELTA Pro 3, so treat both as character, not measurementB0.
“Long regarded as a gold standard for home backup — designed for high-draw appliances and full-scale battery expansion, running home essentials like a fridge, lighting, and a space heater through outages.”

“Heavy but wheeled — integrated wheels and a telescoping handle help move its considerable weight, though they work best on flat, smooth surfaces; a cart is needed for uneven ground.”

“Not silent under heavy load — under 2000W-plus draws the fans emit a noticeable high-pitched whine that's distracting in a quiet room, though it runs quietly enough at lighter loads.”

Who Should Buy Which
Buy the DELTA 3000 Gen4 if you…
- →You'll carry it. 57.3 lb against 99 lb, with a handle at each endA7, and no output given up for it.
- →3,072 Wh covers your longest outage, and you'll never want a second battery.
- →A desktop rides on it. Switchover is rated within 10 ms against no worse than 20 msA8.
- →You'll cycle it for years. It's rated for 6,000 cycles against 3,500.
Buy the DELTA Pro if you…
- →You'll grow it. It takes EcoFlow's extra batteries; the DELTA 4 (3000) can'tA6.
- →You'll lean on solar. 1,600 W of panel input against 1,000 WA5.
- →You need power before December. The DELTA 4 (3000) ships in early DecemberA10.
- →You want a car socket. Our record lists a 12 V car outlet and an RV outlet on the DELTA Pro; the DELTA 4 (3000) has no car socketA3.
If neither fits
If all you need is a CPAP and a phone on camping trips, skip both. A CPAP night uses 12% of the DELTA 4 (3000)'s usable battery, so a much smaller, lighter station does that job for far less.
The Bottom Line
If 3,072 Wh is enough, I'd buy the DELTA 4 (3000). It runs everything the DELTA Pro runs, 41.7 lb lighter, for less money.
If you'll ever want a second battery, buy the DELTA Pro. It's heavy, but it's the one with a port.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DELTA 4 (3000) as powerful as the DELTA Pro?
Yes. Both are rated 3,600 W continuous with a 7,200 W surge at 120 V. The DELTA Pro holds more battery, 3,600 Wh against 3,072 Wh, and the DELTA 4 (3000) weighs 41.7 lb less.
Can you add a battery to the EcoFlow DELTA 4 (3000)?
No. It has no extra-battery port, so 3,072 Wh is all it will ever hold. The DELTA Pro takes EcoFlow's expansion batteries.
How much does the DELTA 4 (3000) cost in the US?
EcoFlow lists it at $1,699 on its US store, and it ships in early December. The DELTA Pro sells for $1,899.
How fast does the DELTA 4 (3000) charge from the wall?
Up to 1,800 W by EcoFlow's figure. At 120 V that's 15 A, the full rating of an ordinary 15 A circuit, so on a shared circuit set a lower rate in the EcoFlow app.
Which lasts longer, the DELTA 4 (3000) or the DELTA Pro?
EcoFlow rates the DELTA 4 (3000) for 6,000 cycles and the DELTA Pro for 3,500. At one full cycle a day, that's about 16.4 years against 9.6.
