EcoFlow DELTA 3000 Gen4 vs Jackery HomePower 3600 Pro MaxThe Lighter Box Can Never Grow. Is 3,072 Wh Enough?
Only one of these can grow past the battery you buy, and it's the one that starts bigger. I'd put the Jackery on the house, unless the box travels more than it sits and 3,072 Wh covers your longest outage.

Gunner’s take
Whole-Home Backup Tester
The DELTA 4 (3000) has no battery port, and that decides most of this page.
It holds 3,072 Wh the day it arrives and 3,072 Wh for goodA6. Jackery's HomePower 3600 Pro Max starts at 3,584 Wh and takes expansion batteries. EcoFlow lists its box at $1,699 and the Jackery sells for $1,799, so the bigger battery is also the cheaper one per watt-hour.
The Jackery also has the bigger inverter and the only 240 V outlet.
It runs 4,000 W and surges to 8,000 W. The DELTA 4 (3000) runs 3,600 W from 120 V outlets and surges to 7,200 WA2. A fridge, a furnace blower and a router fit on either. A 240 V well pump fits on one.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
The Jackery's shortfall is a shopping trip. Add a battery and the gap closes. The DELTA 4 (3000)'s shortfall is permanent, because there is nowhere to plug a battery inA6. Outgrow it and the upgrade is a second station, or the bigger DELTA 4, which does take extra batteriesA6.
DELTA 4 (3000): 3,072 Wh, no extra-battery portA6HomePower 3600 Pro Max: 3,584 Wh, takes Jackery expansion batteriesVan Life Daily needs 4,685 Wh: the DELTA 4 (3000) comes up 2,074 Wh short, the Jackery 1,639 Wh short
Why it mattersIf your outage list might grow, a sump pump this year and a chest freezer next, start with the box that grows.
continuous output
I wire houses for a living, so here's the view from the panel. The Jackery's switchover only reaches circuits an electrician has moved to a sub-panel, and together they have to stay under 4,000 WB1B2. That's an install to budget for. The DELTA 4 (3000) has no 240 V outlet at all, so a 240 V well pump is off its list whatever you spend on wiring.
HomePower 3600 Pro Max: 4,000 W continuous, 8,000 W surge, one 240 V outletDELTA 4 (3000): 3,600 W continuous, 7,200 W surge, 120 V outletsA2Commenters under a Jackery review note its automatic switchover needs a dedicated sub-panel or Jackery's smart panel to reach house circuitsB2, and that its inverter carries no more than 4,000 W once the grid dropsB1
Why it mattersIf a 240 V load or a sub-panel is in your plan, the Jackery is the only candidate on this page.
weight
Five outlets put a fridge, a freezer, a lamp and a router straight into the DELTA 4 (3000) with no power strip. There's one catch on the USB side: EcoFlow says the two 65 W ports and the USB-A share 16 W when used togetherA3, so the 140 W port is the only serious laptop charger. And 17 lb is the line between a lift I'd do alone and one a reviewer says takes two peopleB8.
DELTA 4 (3000): five AC outlets, four rated 20 A and one 30 A twist-lock; USB-C at 140 W, 65 W and 65 WA3HomePower 3600 Pro Max on our record: two standard outlets, one 240 V outlet, one 100 W USB-C57.3 lb against 73.9 lb
Why it mattersIf the box moves and everything plugs into its face, the DELTA 4 (3000) is the handier one.
The specific dimensions that decide these two units — everything else is a tie.
Growth Path
Selected because: The DELTA 4 (3000) stops at 3,072 Wh. The Jackery starts at 3,584 Wh and takes expansion batteries.
solar input
The DELTA 4 (3000) is finished the day it arrives. EcoFlow lists no extra-battery port for itA6, so 3,072 Wh is the most it will ever hold. That covers the 1,645 Wh blackout night on this page with room left. Two of those nights back to back, with no recharge in between, don't fit.
The Jackery leaves the door open. It takes Jackery's own expansion batteries. I won't quote a ceiling, because the published figures disagree with each otherB0. If you like the EcoFlow and want room to grow, the bigger DELTA 4 has the battery port this one lacksA6.
What the Specs Don't Tell You
Selected because: Only the Jackery has a 240 V outlet, and it surges to 8,000 W against 7,200 W.
For motors, the Jackery has more in reserve. It surges to 8,000 W against 7,200 W, and a compressor pulls hardest the instant it starts. A fridge or a sump pump starts on either. Anything on 240 V only has the Jackery.
The switchover ratings match, and neither is a lab number. Both promise no worse than 10 ms. A press reviewer who lived with a 10 ms switchover on another brand says he never noticed it happenB6. EcoFlow's FAQ adds that the DELTA 4 (3000) doesn't support HIDA8, the USB link a UPS uses to tell a computer to shut down.
Portability & Form Factor
Selected because: 57.3 lb against 73.9 lb, for 512 Wh less battery.
weight
I'd lift the DELTA 4 (3000) alone and the Jackery with a friend. The EcoFlow is 57.3 lb with a handle at each endA7. The Jackery is 73.9 lb, and one reviewer says getting it into a pickup takes two peopleB8.
EcoFlow calls it the lightest box in its class, and on this page it is. That's EcoFlow's own claim, made about 3 kWh, 3,600 W unitsA7. If you'd rather roll it, EcoFlow sells a folding cart separatelyA7. For a box that parks beside a sub-panel, none of this matters after the first afternoon.
Your Life, Your Pick
Selected because: Both cover a blackout night. Weekend Camping goes to the Jackery on margin.
A blackout night doesn't separate them. The 1,645 Wh outage leaves the DELTA 4 (3000) 966 Wh in hand and the Jackery 1,401 Wh. A CPAP night, a workday and a tailgate are easy for both.
Camping goes to the Jackery on margin, not on comfort. The 2,100 Wh weekend leaves it 946 Wh against 511 Wh, which is slack for a cold extra night. You'll still be hauling the heavier box to the site. Van Life Daily needs 4,685 Wh and beats both, and only the Jackery can add a battery to get there.

Weekend Camping
Two nights off-grid with essential comfort
HomePower 3600 Pro Max
Both get through the 2,100 Wh weekend. The Jackery finishes with 946 Wh to spare against 511 Wh, the margin that covers an extra cold night.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Either unit
Both survive the blackout with similar margin, and both list a UPS mode — compare their stated switchover classes, and remember those are manufacturer ratings, not measurements.
Battery budget usedlower = more headroom
LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h
SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP is about 40W for eight hours, so both of these cover the night several times over — capacity isn't the question here. The only published difference is fan noise, and it can't settle this: the HomePower 3600 Pro Max is rated 30dB and the DELTA 3000 Gen4 40dB, but the HomePower 3600 Pro Max's is its maker's best case and the DELTA 3000 Gen4's is EcoFlow's maximum under heavy charge and discharge, so at a 40W draw the real gap can only be narrower than it looks, and may even run the other way. Neither settles which box is quieter at a bedside. Buy whichever is cheaper or easier to carry.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
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.
Battery budget usedlower = more headroom
LOAD Laptop 60W×8h · External Monitor 30W×8h · Router + Modem 20W×8h · Phone Charger 15W×2h
SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
Either unit
Both handle the 670 Wh party with most of the battery left. Weight breaks the tie, and the DELTA 4 (3000) is 17 lb lighter to carry from the car.

Conclusion
November 4, 2026
Verdict: the HomePower 3600 Pro Max, on Power Score margin
For a house, I'd buy the Jackery. At $1,799 against $1,699 it costs less per watt-hour, holds 512 Wh more, runs 4,000 W against 3,600 W, has the only 240 V outlet on this page and takes expansion batteries. The DELTA 4 (3000) has no extra-battery port at allA6. Both carry 6,000-cycle ratings, so the Jackery is also the cheaper one to own per kWh, $0.08 against $0.09, and you can order it today while EcoFlow ships the DELTA 4 (3000) in early DecemberA10. The EcoFlow is 17 lb lighter with five outlets on its face, so if the box rides to a cabin and 3,072 Wh is enough, it's the handier one.

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 HomePower 3600 Pro Max rates 4.3/5 (57th percentile of 22 Home Backup-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
17 lb More, 512 Wh More
The Jackery weighs 73.9 lb against 57.3 lb for the DELTA 4 (3000). Beside a sub-panel that costs you one afternoon. On the drive to a cabin it costs you every trip.
What You Buy Is the Ceiling
The DELTA 4 (3000) has no battery port, so 3,072 Wh is as big as it gets. The Jackery starts at 3,584 Wh and takes expansion batteries. If two nights instead of one is on your wish list, start with the one that grows.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. Both figures are maximums rather than guarantees: EcoFlow's depends on registering the unit in the EcoFlow app, which adds two years to a three-year standard term; Jackery's on registering the unit with Jackery, which is what extends the base term to the full period.

Analyst note
The DELTA 3000 Gen4 is cheaper to buy, but the HomePower 3600 Pro Max is cheaper to own. At $0.08/kWh over its lifetime vs $0.09/kWh, the HomePower 3600 Pro Max's higher cycle life and capacity make each dollar go further over the years. One thing to know reading the table: both carry the same 6,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.
Brand trust
EcoFlow
Ecosystem
Largest in portable power — 12-15 models across DELTA Pro, DELTA 3, and RIVER 3 series, plus solar panels and smart home panels
Support
US-based phone/email/chat support (1-800-368-8604). Experiences are polarized — many report hassle-free prepaid-label replacements, but others report long waits and refurbished units sent for new claims. Pro tip: buying from Costco or Amazon gives you a stronger return safety net.
Community
Largest community in the space — Reddit r/Ecoflow_community (~31K members), multiple Facebook groups, and an official community forum
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
Fastest-charging technology (X-Stream), deepest product ecosystem, and most active innovation cadence. At the top of the range sit two whole-home paths: the TITAN line, one 5 kWh unit that grows to 30 kWh, and the DELTA Pro Ultra platform, which stacks batteries and inverters further — flagship paths, not line-wide features.
Worth knowing
Tested subscription paywalls for advanced app features in early 2025 before community backlash paused the plan. No parts or service offered out of warranty.
Jackery
Ecosystem
12-15+ models across Explorer (portable) and HomePower (home backup) series, plus SolarSaga panel ecosystem and innovative form factors
Support
US-based support but widely criticized. Reddit reports describe slow/dismissive responses, scripted AI agents, strict receipt requirements for warranty claims, and refurbished replacements for clearly defective units. Strongly recommended: buy from Costco or Amazon for return protection.
Community
Smallest community of the major brands — Reddit r/Jackery has ~2,000 members. YouTube presence is solid due to brand recognition.
App experience
Rated 2.3-3.3/5 iOS and Android — the weakest app experience of the major brands. Multiple confusing apps (Jackery app vs Jackery Home) and mandatory login even offline.
Unique strength
Highest brand recognition and widest retail distribution (Costco, Home Depot, Best Buy, Amazon). The "Toyota" of power stations — dependable, proven, wide availability. Innovative form factors like the Solar Gazebo and Solar Mars Bot.
Worth knowing
A couple of older models still ship NMC chemistry with a shorter rated lifespan, so check the cycle rating on the specific unit — though most of the current line has moved to LFP. Generally perceived as overpriced for the specs offered compared to newer competitors. App experience is significantly behind rivals.
Analyst note
EcoFlow and Jackery are close competitors. Both have established support channels and growing ecosystems. Compare their specific warranty terms and community size for your peace of mind.
Growth path

FIXED CAPACITYFixed at 3,072Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.
Accepts up to 1,000W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.
HomePower 3600 Pro Max
EXPANDABLESupports Jackery expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 3,584Wh.
Accepts up to 1,200W of solar. Enough for a serious multi-panel array.

Analyst note
The DELTA 3000 Gen4 is sealed at 3,072Wh, which is fine if that covers you. The HomePower 3600 Pro Max starts at 3,584Wh and can grow beyond it with Jackery expansion batteries — real headroom the DELTA 3000 Gen4 doesn't have if your needs climb toward partial-home backup.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3000 Gen4
Nobody owns a DELTA 4 (3000) yet. EcoFlow put it on sale on November 4 and ships it in early DecemberA10, so everything here comes from EcoFlow's US store page and our own arithmeticA1A4.
I'd want a clamp meter on its wall cord. It charges at up to 1,800 W, which by our arithmetic is 15 A at 120 V, the full rating of an ordinary 15 A circuitA4. Hypothetically, I'd plug it into a kitchen circuit with the fridge on it, start a full-speed charge and watch the breaker. My bet is I'd be turning the rate down in the EcoFlow app inside a minuteA4.
“Capacity 3,072 Wh, LFP (LiFePO4) cells. EcoFlow sells it as the DELTA 3000 Gen4; buyers and the press call the pair the DELTA 4.”

Field data on the Jackery is thin, and it comes from reviewers rather than owners. It launched in 2026, and what exists is a handful of reviews and the comments under themB0. One reviewer says it takes two people to get it into a pickupB8.
The comments keep circling the transfer switch. Commenters point out that its automatic switchover needs a dedicated sub-panel or Jackery's smart panel to reach house circuitsB2, and ask how a 4,000 W inverter backs up a whole houseB1B4. It's a fair question for either of these boxes.
“Regarding your dislike of inverter fail to stay on if > 4000W passthrough is terminated, it's understandable. It's internal inverter can only handle 4000W 240V.”

Recurring owner themes
- Launch-day ledger: every entry is EcoFlow's own US store and documentation, or our labelled arithmetic. No owner or reviewer evidence exists yet. [DELTA 3000 Gen4 · 12 entries]
- Commenters and a press reviewer repeatedly question whether the marketed automatic transfer switch delivers true whole-home UPS coverage, given the 4,000W continuous ceiling and a gap between switchover-speed marketing claims and what testers actually notice in practice. [HomePower 3600 Pro Max · 3 entries]
- Getting the full ATS benefit requires extra infrastructure (a dedicated sub-panel or Jackery's smart panel), and the solar input uses a proprietary connector rather than the industry-common XT60. [HomePower 3600 Pro Max · 2 entries]

“Regarding your dislike of inverter fail to stay on if > 4000W passthrough is terminated, it's understandable. It's internal inverter can only handle 4000W 240V.”

“Most homeowners use a generator input with a MANUAL interlock switch...you still have to manually flip the interlock to get power back into the house. To make the ATS work as intended, you need a dedicated sub-panel or Jackery's smart panel.”

Who Should Buy Which
Buy the DELTA 3000 Gen4 if you…
- →You'll carry it. 57.3 lb against 73.9 lb.
- →You plug things in rather than wire it in. Five outlets on the front, one of them a 30 A twist-lockA3.
- →Your longest outage fits in 3,072 Wh, and you're sure it always will.

Buy the HomePower 3600 Pro Max if you…
If neither fits
If you want the whole house to switch over by itself, central air included, neither inverter is big enough. That's a whole-home battery wired into the main panel, EcoFlow's TITAN line among them, and a conversation with an electrician.
The Bottom Line
If it's going on house circuits, buy the Jackery. It holds more, speaks 240 V and grows when your list does, and you can order it today.
If it's a big portable you'll carry, the DELTA 4 (3000) is the lighter, handier box. Just buy it knowing 3,072 Wh is the ceiling, and that EcoFlow ships it in early DecemberA10.
