Head-to-head test
EcoFlow DELTA 3000 Gen4 vs Jackery Explorer 5000 PlusUnder Half the Weight, and Sealed for Life. Enough for a House?
The Jackery starts with a bigger battery than the DELTA 4 (3000) will ever hold, and it has the 240 V outlets a house can ask for. For home backup I'd buy the Jackery, and I'd take the EcoFlow only if the box travels or one night on ordinary outlets is the whole job.

Gunner’s take
Whole-Home Backup Tester
The DELTA 4 (3000) tops out below where the Explorer 5000 Plus begins.
EcoFlow's new unit holds 3,072 WhA1 and has no battery port at allA6. Jackery's holds 5,040 Wh on day one and takes extra batteries up to 60 kWh by Jackery's figureB1. Whatever you buy the EcoFlow for has to fit in 3,072 Wh for good.
What the EcoFlow gives back is weight and money.
It's 57.3 lb with a handle at each endA7. The Jackery is 134.5 lb on wheelsB3. EcoFlow lists the DELTA 4 (3000) at $1,699 and the Jackery sells for $3,149, so the EcoFlow is the cheaper box per watt-hour as well as the lighter one.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
The DELTA 4 (3000) wakes up with 59% of a second night. The sun has to make up the rest, through one 1,000 W input. On a clear day that's plenty, since that input could fill the whole battery in a little over three hours. On a grey one it isn't, and there's no battery to add that would cover the gap.
8-Hour Blackout needs 1,645 Wh: the DELTA 4 (3000) ends with 966 Wh left, the Explorer 5000 Plus with 2,639 WhDELTA 4 (3000): 3,072 Wh, no battery portA6DELTA 4 (3000): one solar input, up to 1,000 WA5
Why it mattersIf your outages run two nights under winter cloud, buy the Jackery. If they end by breakfast, the 3000 is enough.
continuous output
A deep well pump, an electric dryer or a central air handler runs on 240 V. The DELTA 4 (3000) can't plug into any of them. The Jackery can, and one owner who wired it through a transfer switch, the switch that hands chosen house circuits to a battery, found it refills only from solar until the grid returnsB4. Plan the panels before the storm.
Explorer 5000 Plus: 7,200 W continuous, 14,400 W surge, two 240 V outletsDELTA 4 (3000): 3,600 W continuous, 7,200 W surge, 120 V outletsA2One Explorer 5000 Plus owner on an automatic transfer switch can recharge it only from solar while it dischargesB4
Why it mattersIf any load on your list needs 240 V, the 3000 is out before capacity comes up.
rated cycles
Cheap kilowatt-hours only help if there are enough of them on the night you need them. If one outage fits inside 3,072 Wh, the EcoFlow is the better deal. If it doesn't, you'll run out at 2 a.m. no matter what each kWh cost.
$1,699 for 3,072 Wh against $3,149 for 5,040 Wh6,000 rated cycles against 4,000Over the rated life: 18,432 kWh for the DELTA 4 (3000), 20,160 kWh for the Explorer 5000 Plus
Why it mattersIf one night of a fridge, a router and lights is the job, buy the 3000. If your list is longer, the $1,450 buys capacity you'll actually use.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Both finish the 8-hour blackout. One ends with 966 Wh left, the other with 2,639 Wh.
The first night is a draw. The second night isn't. Our 8-hour blackout uses 1,645 Wh. The DELTA 4 (3000) finishes it with 966 Wh, 59% of a second night. The Jackery finishes with 2,639 Wh, enough for 1.6 more nights like it.
The two trips go to the EcoFlow, because the Jackery stays home. Nobody hauls 134.5 lb to a campsite. The camping weekend's 2,100 Wh leaves the 3000 with 511 Wh, so it's closer than the win suggests. Van Life Daily asks for 4,685 Wh, and neither does it alone: the 3000 comes up 2,074 Wh short and the Jackery 401 Wh.
Growth Path
Selected because: The DELTA 4 (3000) is sealed at 3,072 Wh. The Explorer 5000 Plus starts at 5,040 Wh and takes extra batteries.
solar input
I went through EcoFlow's US store page looking for a battery port, and there isn't one. EcoFlow lists extra batteries only for the bigger DELTA 4A6. Outgrow 3,072 Wh and your next step is a second station. The Jackery's next step is a battery, and Jackery quotes 60 kWh at the topB1.
Sealed is fine if 3,072 Wh covers you. The blackout night uses 63% of what the 3000 can deliver, so a fridge, a router and lights fit with room left. If you've already added up your loads and landed near 5,040 Wh, believe the list. This box can't follow you there.
Lifetime Value
Selected because: 6,000 rated cycles against 4,000, on batteries of 3,072 Wh and 5,040 Wh.
cost / lifetime kWh
Per kWh over its life, the EcoFlow is the cheaper box. Spread each price over the energy its rated cycles deliver and the DELTA 4 (3000) comes to $0.09 against $0.16, about three-fifths of the Jackery's cost. EcoFlow rates it for 6,000 cycles and Jackery rates its unit for 4,000, which at one cycle a day is 16.4 years against 11.
The Jackery still puts more energy through its life. Its bigger battery delivers 20,160 kWh before it reaches its rating, against 18,432 kWh for the 3000. A box that waits at full charge for two storms a year gets nowhere near either figure. Run it off solar every day and they matter, but cheaper kWh only help if they're enough.
Portability & Form Factor
Selected because: 57.3 lb against 134.5 lb. One goes in a car, and the other rolls into place and stays.
weight
I'd lift the DELTA 4 (3000) into a car trunk by myself. It's 57.3 lb with a handle at each end, and EcoFlow sells a folding cart for it separatelyA7. That's a box that goes to the cabin on Friday and comes back on Sunday.
The Jackery moves the way a fridge moves. It has real wheels, a sturdy suitcase handle and side handles for two peopleB3. Roll it next to the panel once and leave it there. If the box never moves, weight decides nothing here.

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 Explorer 5000 Plus is rated 30dB and the DELTA 3000 Gen4 40dB, but the Explorer 5000 Plus'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.

The Explorer 5000 Plus at 134.5 lbs is not a take-along — it rolls off a truck bed if it travels at all, so this scenario belongs to the DELTA 3000 Gen4 by default — and it earns it, covering the 670Wh with 1,941Wh to spare.

Conclusion
November 4, 2026
Verdict: the Explorer 5000 Plus, on Power Score margin
For a house, I'd buy the Explorer 5000 Plus. It starts at 5,040 Wh against 3,072 Wh, runs 7,200 W against 3,600 W, has 240 V outlets and takes Jackery's extra batteriesB1. The DELTA 4 (3000) has no battery port, so 3,072 Wh is where it staysA6. The EcoFlow is the better buy for a box that travels, at 57.3 lb against 134.5 lb, or for one night of a fridge, a router and lights, and at $1,699 against $3,149 it's the cheaper of the two per watt-hour and per lifetime kWh. The call flips to the EcoFlow only if 3,072 Wh truly covers your longest outage, because then the $1,450 buys headroom you won't use. The Jackery is also on sale now, and EcoFlow ships the DELTA 4 (3000) in early DecemberA10.

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 Explorer 5000 Plus rates 4.8/5 (90th 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.
One Rides in the Car, One Rolls to the Panel
The DELTA 4 (3000) is 57.3 lb, a one-person lift. The Explorer 5000 Plus is 134.5 lb on wheels, a two-person lift that stays where you park it. If the box never moves, skip this card.
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 Explorer 5000 Plus starts at 5,040 Wh and takes Jackery's extra batteries on top. If your list might grow, this is the card to read twice.
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 Explorer 5000 Plus 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. 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. Worth saying because the per-dollar framing can suggest otherwise: the DELTA 3000 Gen4 works out at 2.9 years of cover per $1,000 spent against the Explorer 5000 Plus's 1.6, but that spread is the price gap, not the terms.
More Cycles, Fewer Total kWh
The DELTA 4 (3000) is rated for 6,000 cycles and the Explorer 5000 Plus for 4,000, which at one cycle a day is 16.4 years against 11. The Jackery's bigger battery still delivers more over its rating, 20,160 kWh against 18,432 kWh.

Analyst note
The DELTA 3000 Gen4 wins on both sticker price and long-term value. At $0.09/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner. One caution on the lifespan row: the DELTA 3000 Gen4 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the Explorer 5000 Plus still delivers more over its shorter horizon (20,160 vs 18,432 kWh). Years measure wear, not usefulness.
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

Analyst note
The DELTA 3000 Gen4 is sealed at 3,072Wh, which is fine if that covers you. The Explorer 5000 Plus starts at 5,040Wh 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 in the US on November 4 and says it ships in early DecemberA10, so everything here comes from EcoFlow's US store page and our arithmeticA1A2A6.
I'd want to watch the second night before I trusted it with one. Hypothetically, I'd run a fridge, a router and lights through a night, then put a 1,000 W array on its single solar inputA5 on an ordinary November day and see whether it's full by dark. That test decides whether a sealed 3,072 Wh is enough for a storm.
“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.”

Jackery Explorer 5000 Plus
The Jackery's record here is short and friendly. One review scores it 9.3 out of 10B2, and another singles out real wheels and a sturdy suitcase handleB3. That's a pair of write-ups, not a crowd of long-term ownersB0.
One owner's note matters for anyone wiring it in. On an automatic transfer switch, while it's discharging, the Explorer 5000 Plus refills only from solar until grid power returnsB4. If it carries the house, size the panels for that.

“US unit: 120 V AC, 60 Hz; rated 3,600 W continuous with a 7,200 W surge. It supports X-Boost (EcoFlow refers to the manual for the US X-Boost figure); X-Boost is unavailable while the unit charges from the wall or runs in bypass.”

“AC input 100–120 V, 15 A, 50/60 Hz; X-Stream charging up to 1,800 W from a US wall outlet. Our arithmetic: 1,800 W at 120 V is 15 A, the full rating of an ordinary 15 A circuit, so on a shared circuit you would set the charge rate lower in the EcoFlow app.”

Who Should Buy Which
Buy the DELTA 3000 Gen4 if you…
- →The box has to travel. 57.3 lb goes in a car. 134.5 lb doesn't.
- →One night is the job: a fridge, a router and lights, with 966 Wh left by morning.
- →Nothing on your list needs 240 V. Its outlets are 120 V onlyA2.
- →A desktop PC sits on it. It's rated to switch over in no worse than 10 ms against 20 ms.
Buy the Explorer 5000 Plus if you…
- →This is for the house. 5,040 Wh to start, and Jackery's extra batteries after thatB1.
- →Something runs on 240 V, like a well pump or an electric dryer.
- →Your outages run past one night. It finishes our blackout with 2,639 Wh to spare.
- →You want it before December. It's on sale now, and EcoFlow ships the DELTA 4 (3000) in early DecemberA10.
If neither fits
If the job is a CPAP through the night, both are far more box than you need. The CPAP night uses 12% of the DELTA 4 (3000). A small portable unit does it for a fraction of either price, and you can carry it to the bedroom.
The Bottom Line
For a house, buy the Explorer 5000 Plus. It starts with more battery than the DELTA 4 (3000) can ever hold, has the 240 V outlets, and grows from thereB1.
If the box travels, or one night on ordinary outlets is the whole job, the DELTA 4 (3000) is the smarter buy. It does that at under half the weight for $1,699, and it's the cheaper of the two to own per kWh.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
How much is the DELTA 4 (3000) in the US, and when does it ship?
EcoFlow lists it at $1,699 on its US store. It went on sale on November 4, 2026, and EcoFlow says it ships in early December. The Explorer 5000 Plus sells for $3,149 and is on sale now.
Can the DELTA 4 (3000) add extra batteries?
No. It has no battery port, so 3,072 Wh is all it will hold. The Explorer 5000 Plus starts at 5,040 Wh and takes Jackery's extra batteries.
Can the DELTA 4 (3000) run 240 V appliances?
No. Its outlets are 120 V only. The Explorer 5000 Plus has two 240 V outlets for loads like a well pump or an electric dryer.
Which one lasts longer in a power outage?
The Explorer 5000 Plus. Our 8-hour blackout leaves it with 2,639 Wh against 966 Wh for the DELTA 4 (3000). That's more than another full night on the Jackery and a bit over half a night on the EcoFlow.
How fast does the DELTA 4 (3000) charge from the wall?
EcoFlow rates it at up to 1,800 W from a US outlet. That's 15 A at 120 V, the full rating of an ordinary 15 A circuit, so on a circuit you share you'd set it lower in the EcoFlow app.
