EcoFlow DELTA 3 Ultra vs Jackery HomePower 3000

Two ~3kWh units at the same $1,199: the EcoFlow DELTA 3 Ultra out-specs on output, surge, solar, and a faster UPS, and it expands where the sealed Jackery HomePower 3000 can't — but the HomePower answers with 13 lbs less weight (the world's lightest 3kWh unit) and Jackery's low failure record.

Two 3kWh power stations at the identical price of $1,199, and they split along a familiar line: capability versus portability. The EcoFlow DELTA 3 Ultra is the more powerful, expandable unit; the Jackery HomePower 3000 is the lighter, more compact one, billed as the world's smallest 3kWh stationB1.

The DELTA 3 Ultra's edges are output and flexibility. It runs 3,600W to the HomePower's 3,000W, surges to 7,200W against 6,000W, takes 1,600W of solar to 1,400W, switches over in 10 ms to the HomePower's 20, and — the big one — expands past its 3,072Wh base, where the HomePower is sealed at 3,024Wh.

The HomePower 3000's answer is its body. At 63.9 lbs it's 13 lbs lighter than the 77.2-lb DELTA — remarkable for 3kWh, thanks to a cell-to-body designB1 — and it fits tighter spaces. Jackery also carries the lowest failure and warranty-claim rate among the majorsB2. A note on longevity: our data lists it at 2,000 cycles, but Jackery and reviewers rate it closer to 4,000B3, so it likely lasts far longer than that figure implies.

02

What the Numbers Reveal

Each conclusion stated first — the numbers behind it on one line, the full analysis below.

F1

It runs 3,600W to the HomePower's 3,000W, surges to 7,200W against 6,000W, and — unlike the sealed HomePower — accepts expansion batteries past its 3,072Wh base.

DELTA 3600W output vs HomePower 3000WDELTA 7200W surge vs HomePower 6000WDELTA expandable; HomePower sealed

Why it mattersFor running the biggest loads and growing capacity later, the DELTA 3 Ultra is the more capable, future-proof unit.

F2

At 63.9 lbs it's 13 lbs lighter than the DELTA, billed as the world's lightest and smallest 3kWh station thanks to a cell-to-body design, and compact enough at 16.4 inches wide to fit spaces that reject rivalsB1.

HomePower 63.9 lbs vs DELTA 77.2HomePower billed the world's lightest and smallest 3kWh stationB1HomePower is one-person carriable at ~60 lbs, 16.4 inches wideB1

Why it mattersFor a 3kWh unit you'll move or squeeze into a tight spot, the HomePower is markedly the easier one to live with.

F3

Our data lists the HomePower at 2,000 cycles — which would make it costlier to own — but Jackery and multiple reviewers rate its LFP cells nearer 4,000B3, the same class as the DELTA's, so the real cost-to-own gap is likely small or nil.

DB lists HomePower at 2,000 cycles vs DELTA 4,000Jackery and reviewers rate the HomePower's cells nearer 4,000B3Cost-to-own of $0.20 vs $0.10 rests on the low cycle figure

Why it mattersDon't read the raw cost-to-own figure as decisive; on longevity these two are probably much closer than the spec sheet shows.

F4

Both cover a camping weekend (80-82%), an 8-hour blackout, and a workday with room to spare, but the DELTA's 10 ms UPS beats the HomePower's 20 for sensitive gear, while both fall short only of a full van-life day.

Both ~3kWh handle a weekend, blackout, and workday with roomDELTA 10 ms UPS vs HomePower 20 msBoth fall short only of a full van-life day

Why it mattersFor everyday backup either is ample; the DELTA edges the UPS margin, and only expansion separates their ceilings.

The specific dimensions that decide these two units — everything else is a tie.

Lifetime Value

Selected because: The cost-to-own gap rests on a disputed cycle count worth explaining.

cost / lifetime kWh

On the raw numbers, the DELTA 3 Ultra looks far cheaper to own — $0.10 per lifetime kWh to the HomePower's $0.20 — but that gap rests on a disputed figure. Our data lists the HomePower at 2,000 cycles, while Jackery and multiple reviewers rate its LFP cells nearer 4,000B3, the same class as the DELTA's 4,000-cycle rating.

If the higher, better-supported figure is right, the HomePower's real cost-to-own is roughly half what the spec sheet shows — landing close to the DELTA's. So treat the headline lifetime-value gap with caution: at the same $1,199 price and similar likely longevity, neither has a clear cost-to-own advantage, and the decision should rest on capability, weight, and expandability instead.

Growth Path

Selected because: Expansion is the DELTA's clearest structural advantage over the sealed HomePower.

solar input

This is the DELTA 3 Ultra's structural win: it accepts EcoFlow expansion batteries, so its 3,072Wh base can grow into a much larger bank, while the Jackery HomePower 3000 is sealed at 3,024Wh — what you buy is the ceiling. For a whole-home or extended-off-grid setup, that difference is decisive.

The HomePower's sealed design keeps it lighter and more compact, which is part of its appeal — but it means a hard cap. If your needs might grow past 3kWh, the DELTA can follow without a full replacement; the HomePower would need to be sold and re-bought, or paired with a second unit. For flexibility, the DELTA is clearly the more future-proof platform.

Portability & Form Factor

Selected because: The HomePower's 13-lb-lighter, compact body is its standout strength.

weight

Here the HomePower 3000 shines, and it's genuinely impressive: at 63.9 lbs it's 13 lbs lighter than the DELTA's 77.2, and billed as the world's lightest and most compact 3kWh station thanks to a cell-to-body design — one person can carry it, and at 16.4 inches wide it fits spaces that reject bulkier rivalsB1. For a battery this size, that's a real engineering feat.

The DELTA is no slouch to move — reviewers note wheels and a telescoping handle make its 77 lbs manageableA14 — but it's the heavier, larger unit. So if the station will travel, get squeezed into a closet or RV bay, or ever need a solo lift, the HomePower is the easier body to live with; if it'll mostly stay put, the DELTA's weight matters less against its capability edge.

Brand Trust

Selected because: EcoFlow's ecosystem vs Jackery's low failure record is a real tiebreaker.

The brands split as they usually do. EcoFlow brings the deepest ecosystem, the fastest-charging tech, and an app among the best in the category — the DELTA 3 Ultra's expandability and refinement are classic EcoFlow, though a past DELTA Max 2000 recall is worth noting. Jackery is the widely-recognized 'Toyota' of power stations, with the broadest retail reach and, notably, the lowest reported failure and warranty-claim rate among the majorsB2.

The trade-off is software and support process: Jackery's app is the weakest of the major brands, and its warranty service draws criticism, while EcoFlow's support is polarized. But Jackery's low failure rateB2 is a real point in the HomePower's favor for a set-and-forget home-backup unit. Both are safer bought from Costco or Amazon for return protection.

Scenario verdicts

We ran the math on six real-world scenarios. Here's which unit survives your actual life.

SCN-01 · 2 nights · needs 2,100Wh

Weekend Camping

Two nights off-grid with essential comfort

Either unit

A weekend (2,100Wh) fits on both with margin — the DELTA at 80%, the HomePower at 82%. Both cover a real trip; the tiebreaker is handling — the HomePower is 13 lbs lighter to haul to a remote site, while the DELTA's higher output and expandability suit a bigger or growing camp. For a solar-supported weekend, the DELTA's 1,600W input refills a touch faster.

SCN-02 · 8 hours · needs 1,645Wh

8-Hour Blackout

Keep the essentials running through a night without power

Either unit

A full blackout (1,645Wh) fits on either with room to spare — both around 63-64%. For home backup, the DELTA's faster 10 ms UPS is gentler on sensitive gear, while the HomePower has a proven record — nearly two days on a fridge in testing. Both cover an overnight outage comfortably; the choice is expandability and UPS speed versus weight and reliability.

SCN-03 · 8 hours · needs 320Wh

CPAP Overnight

Sleep therapy without interruption — the #1 medical use case

Either unit

A CPAP uses barely a tenth of either 3kWh unit overnight — capacity is a non-issue. Both are quiet at 30dB and switch over cleanly, so either is an excellent bedside backup. With this light a load, the two are interchangeable; decide on the bigger-picture factors, not this scenario.

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

A full work day draws about a third of either unit, so both cruise through with power to spare. The DELTA's higher output handles a heavier multi-monitor, high-draw desk; the HomePower does the same job in a lighter, more compact body. Either powers a home office all day — pick on portability versus expandability.

Battery budget usedlower = more headroom

LOAD  Laptop 60W×8h · External Monitor 30W×8h · Router + Modem 20W×8h · Phone Charger 15W×2h

Tailgate Party

Game day power for the crew

Either unit

Game day barely touches either at about a quarter of the battery. Both have massive headroom; the practical difference is hauling them — the HomePower is 13 lbs lighter to lift, the DELTA rolls on wheels. Capacity is a non-issue for a single event on either.

Van Life Daily

A full day of mobile living — the ultimate endurance test

Neither unit

A van-life day wants about 4,685Wh, past either 3kWh base (179-182%). The DELTA expands with add-on batteries to climb toward it; the sealed HomePower can't grow, though its light weight and compact size fit a build well. For full-time van power, the DELTA's expandability is the bigger asset — or pair or size up either way.

Conclusion

July 16, 2026

Verdict: the EcoFlow DELTA 3 Ultra

A close cross-brand call at $1,199 each. The EcoFlow DELTA 3 Ultra is the more capable, more flexible pick: it pushes 3,600W to the HomePower's 3,000W, surges to 7,200W against 6,000W, takes more solar (1,600W vs 1,400W), switches over faster (10 ms vs 20), and — crucially — expands past its 3,072Wh base where the sealed HomePower stops at 3,024Wh. The Jackery HomePower 3000 counters with a genuinely impressive body: at 63.9 lbs it's 13 lbs lighter than the 77.2-lb DELTA, billed as the world's lightest and most compact 3kWh unitB1, and it carries Jackery's lowest-in-class failure and warranty-claim recordB2. One caveat on the numbers: our data lists the HomePower at 2,000 cycles, but Jackery and reviewers rate its cells nearer 4,000B3, so its cost-to-own is likely far closer to the DELTA's than the raw spec suggests. Lean DELTA 3 Ultra for output, expandability, and a faster UPS; the HomePower for low weight, compactness, and a proven reliability record.

Test Notes & Caveats

Hidden gotchas and advantages we spotted that you won't find on the product page.

[NOTE]

77 Pounds vs 64 — Light for 3kWh

The DELTA 3 Ultra weighs 77.2 lbs; the HomePower 3000 just 63.9 — 13 lbs less, and genuinely remarkable for a 3kWh unit, which Jackery achieves with a cell-to-body design that also makes it the most compact in its class. Neither is a casual carry, but the HomePower can be moved by one person and squeezed into tighter spaces, while the DELTA leans on wheels and a telescoping handle to manage its greater bulk. If the unit travels or fits into a tight bay, the HomePower's lighter, smaller body is a real advantage.

[NOTE]

The DELTA Grows; the HomePower Is Sealed

The DELTA 3 Ultra accepts EcoFlow expansion batteries to climb past its 3,072Wh base; the Jackery HomePower 3000 is sealed at 3,024Wh — what you buy is the ceiling. For a fixed 3kWh need, both are plenty. But for whole-home backup or a growing off-grid bank, the DELTA can scale without a replacement, while the HomePower would need a second unit or an upgrade. Its sealed design is part of why it's so light and compact — a deliberate trade of flexibility for portability.

[NOTE]

10ms vs 20ms Switchover

The DELTA 3 Ultra switches to battery in 10 ms when the grid drops; the HomePower 3000 takes 20 ms (measured under 20 in testing). Both keep a PC, router, or CPAP running through an outage without a reboot — reviewers saw clean switchovers on each — but the DELTA's tighter 10 ms window is the safer margin for very sensitive electronics like a NAS. It's a modest edge, one of several where the DELTA's spec sheet leads at the same price.

Full record above — the Test Desk pick is the DELTA 3 Ultra.

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. Supports up to 180kWh modular expansion with DELTA Pro Ultra X.

Worth knowing

The Oct 2025 DELTA Max 2000 recall (overheating/fire risk, 6 incidents) is worth noting. Also 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.

All Jackery power stations tested →

Analyst note

EcoFlow and Jackery both sell heavily at retail but pull in different directions. EcoFlow leads with the deepest ecosystem, the fastest-charging tech, an app among the best in the category, and expandable platforms — the DELTA 3 Ultra's power and growth are classic EcoFlow, though a past DELTA Max 2000 recall is worth noting. Jackery is the widely-recognized 'Toyota' of power stations, with the broadest distribution and, notably, the lowest reported failure and warranty-claim rate among the majors — the HomePower 3000's light, compact, proven build is the payoff — but the weakest app of the majors and criticized warranty service. For this pair, it's EcoFlow's more powerful, expandable DELTA against Jackery's lighter, more compact, more proven HomePower, at the same price. Both are safer bought from Costco or Amazon for return protection.

Growth path

DELTA 3 Ultra

EXPANDABLE

Supports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 3,072Wh.

Accepts up to 1,600W of solar. Enough for a serious multi-panel array.

Generous port selection supports complex multi-device setups.

Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.

HomePower 3000

FIXED CAPACITY

Fixed at 3,072Wh — a sealed, complete system. No expansion port, but that capacity already covers heavy and multi-day loads.

Accepts up to 1,400W of solar. Enough for a serious multi-panel array.

Adequate ports for most setups, but heavy users may want a power strip.

DELTA 3 UltraHomePower 3000

Analyst note

The HomePower 3000 is sealed at 3,072Wh, which is fine if that covers you. The DELTA 3 Ultra starts at 3,072Wh and can grow beyond it with EcoFlow expansion batteries — real headroom the HomePower 3000 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 3 Ultra

Reviewers of the DELTA 3 Ultra tier consistently praise its quiet operation — even pushed to maximum output, the fans never become annoying or distracting, a clear step up from older EcoFlow modelsA1A2 — and its UPS behavior, which one tester compared directly to a dedicated APC unit, switching on instantly with no dips when unplugged from the wallA5A6.

Build quality earns repeated marks as substantial and premium, from the casing to the sliding rear port coversA9A15, and while its weight is flagged as hefty, wheels and a telescoping handle make it manageable to cart aroundA14. Coverage of the base Ultra is still thin and overlaps with the Ultra Plus, so long-term owner data is limited.

Even when you're pushing it hard, the DELTA 3 Ultra Plus runs much quieter than older EcoFlow models, like the DELTA 2 Max.

Jackery HomePower 3000

The HomePower 3000's headline is its size-to-power: reviewers call it the world's lightest and smallest 3kWh station, one person can carry its ~60 lbs, and its compact 16.4-inch width fits spaces that reject rivalsB1. In home-backup testing it kept a standard refrigerator running for nearly two days and a 55-inch TV for around 30 hours, with a UPS switchover measured under 20 msB4.

It uses LiFePO4 cells with strong thermal stability that Jackery and reviewers rate around 4,000 cycles — notably higher than some spec listings, so lower cycle figures should be treated with cautionB3. And Jackery carries the lowest reported failure and warranty-claim rate among the major brandsB2, a reassuring record for a set-and-forget backup unit.

Described as the world's lightest and smallest 3kWh power station thanks to an advanced cell-to-body (CTB) design — one person can carry it at around 60 lbs, and its compact 16.4-inch width fits spaces that reject rivals.

    Even when you're pushing it hard, the DELTA 3 Ultra Plus runs much quieter than older EcoFlow models, like the DELTA 2 Max.

    Over my career I have become accustomed to APC batteries immediately switching on when there is a power hit or power shut-off, and the EcoFlow Delta 3 Ultra Plus works in the exact same way.

    It does not feel cheap or fragile. Everything from the outer shell case to the plastic buttons and the AC cable feels substantial and durable enough to withstand day-to-day wear and tear.

    The sturdy telescoping handle and wheels make it effortless to cart around, and if you do have to lift its admittedly somewhat hefty 74 lbs, grab handles are well placed for the task.

    Solid home backup — kept a standard refrigerator running for nearly two days and a 55-inch TV for around 30 hours, with a grid-to-battery UPS switchover measured under 20 milliseconds.

Who Should Buy Which

Buy the DELTA 3 Ultra if you…

  • You want more power and headroom — 3,600W output and a 7,200W surge to the HomePower's 3,000W/6,000W.
  • You might expand — it grows past 3kWh where the sealed HomePower can't.
  • You want the faster UPS and more solar — a 10 ms switchover and 1,600W inputA5.

This is you — check the DELTA 3 Ultra price

Buy the HomePower 3000 if you…

  • You want the lightest, most compact 3kWh unit — 13 lbs lighter and billed the world's smallestB1.
  • You'll fit it in tight spaces or carry it solo — 16.4 inches wide, ~60 lbsB1.
  • You value a proven reliability record — Jackery's lowest-in-class failure rateB2.

If neither fits

Both handle everyday backup easily but fall short of a full van-life day (4,685Wh) on the base — the DELTA expands to close the gap, the sealed HomePower can't. For a whole rig, expand the DELTA or pair units.

08

The Bottom Line

At an identical $1,199, the EcoFlow DELTA 3 Ultra is the more capable, more future-proof 3kWh unit. It out-powers the HomePower on output (3,600W vs 3,000W) and surge (7,200W vs 6,000W), takes more solar, switches over faster, and — most importantly — expands past its base where the HomePower is sealed. For maximum capability and room to grow, it's the stronger buy.

The Jackery HomePower 3000 makes a real case on portability and proof. At 63.9 lbs it's 13 lbs lighter and the most compact 3kWh station madeB1, with Jackery's lowest-in-class failure record behind itB2 — and its longevity is likely far better than the listed 2,000 cyclesB3. If you want the lightest, most compact 3kWh unit for a fixed need and value a proven track record, it's an excellent choice; for power and expandability, the DELTA leads.

Frequently Asked Questions

Answers drawn from the spec record and cited owner research.

EcoFlow DELTA 3 Ultra or Jackery HomePower 3000 — which should I buy?

A close call at $1,199 each. The DELTA 3 Ultra is more capable and flexible — 3,600W output (vs 3,000W), 7,200W surge, a faster 10 ms UPS, more solar, and expandable where the HomePower is sealed. The HomePower 3000 counters with 13 lbs less weight (the world's lightest 3kWh unit) and Jackery's lowest-in-class failure record. Lean DELTA for power and expandability; the HomePower for portability and a proven track record.

Which is lighter and more compact?

The Jackery HomePower 3000, and by a lot for this class — 63.9 lbs to the DELTA's 77.2, billed as the world's lightest and smallest 3kWh station thanks to a cell-to-body design, and just 16.4 inches wide. If you'll carry the unit, fit it into a closet or RV bay, or move it solo, the HomePower is markedly easier to handle. The DELTA is heavier but has wheels and a handle to help.

Is the HomePower 3000 really only good for 2,000 cycles?

Probably not — that figure appears understated. Jackery and multiple reviewers rate its LFP cells around 4,000 cycles, the same class as the DELTA 3 Ultra's rating. So while some spec listings (including ours) show 2,000, its real longevity is likely much higher, and its cost-to-own is probably far closer to the DELTA's than the raw number suggests. Treat the low cycle figure with caution.

Which expands, and does it matter?

Only the DELTA 3 Ultra — it accepts EcoFlow expansion batteries to grow past its 3,072Wh base, while the HomePower 3000 is sealed at 3,024Wh. For a fixed 3kWh need both are plenty, but if there's any chance you'll want more — whole-home backup, a bigger off-grid bank — the DELTA can scale and the HomePower can't. That expandability is the DELTA's clearest structural advantage.
