Head-to-head test
EcoFlow DELTA 3 Plus vs Jackery HomePower 3000
This is capacity against carry: the HomePower 3000 finishes every sustained load the DELTA 3 Plus quits on and costs less per kilowatt-hour doing it, so it wins for everyone but the light-load buyer who carries the box more than they fill it.

Spec deltas
Three times the capacity for 1.67 times the price. That is the HomePower 3000 against the DELTA 3 Plus, and it settles most of this page. The Jackery covers a weekend, a blackout, and a full workday with energy to spare. The EcoFlow is a 1,024Wh box with about 870Wh usable after a flat 15% derate, and it runs out partway through each of those.
Capacity is not free to carry, though. The DELTA is 27 lbs, a one-hand grab off a shelf. The HomePower is 59.5 lbs, a two-hands lift heavier than a checked bag at the airline limit. On light loads the gap stops mattering: a CPAP, some phones, a few lights, and both finish the night. The Jackery's extra usable capacity, 2,611Wh against 870, becomes reserve you never reach while you haul the weight and pay the $680 difference between $719 and $1,399 anyway.
So the question is not which unit is better. It is which job you are buying for. Fill it more than you carry it and the HomePower is the capable pick and, at $0.10 per lifetime kWh against $0.18, the cheaper one to own. Carry it more than you fill it and the DELTA is half the weight for hundreds less. The verdict leans Jackery because most people who cross-shop a 3kWh station have loads that need it, but the case for the DELTA is real, not a consolation prize.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
Across a camping weekend (2,100Wh), an 8-hour blackout (1,645Wh), and a full remote workday (910Wh), the DELTA finishes none of them and the HomePower finishes all three. The single axis that sorts this matchup is whether your session ever crosses about 870Wh.
DELTA 3 Plus: 1,024Wh, about 870Wh usable after the flat 15% derateHomePower 3000: 3,072Wh, about 2,611Wh usableWeekend Camping needs 2,100Wh: the DELTA covers 41% and stops 1,230Wh short, the HomePower finishes with 511Wh to spare
Why it mattersIf any load you care about runs past roughly 870Wh, the DELTA is out before price or brand even enters the conversation.
Typical price
Three times the capacity comes at 1.67 times the price ($1,399 vs $719), and because both packs carry the same 4,000-cycle rating, the HomePower spreads its cost over 12,288 lifetime kWh against the DELTA's 4,096. You do not pay a capacity premium here; you get a discount for sizing up.

Why it mattersAnyone who will use even a third of the HomePower's capacity is buying their watt-hours cheaper than the DELTA sells them.
weight
A CPAP pulls about 320Wh, and the DELTA covers it with 550Wh to spare. Every watt-hour of the HomePower's 2,291Wh margin past that is capacity you paid for, carry, and never touch. For light, mobile use the DELTA delivers the same night for hundreds less and half the weight.
CPAP Overnight needs about 320Wh: the DELTA keeps 550Wh usable in reserve, the HomePower 2,291WhDELTA 3 Plus: 27 lbs; HomePower 3000: 59.5 lbsDELTA 3 Plus: $719; HomePower 3000: $1,399
Why it mattersIf your real draw is a CPAP, phones, and lights, the DELTA is the buy and the HomePower is overkill you would lug around.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Every load that needs real energy, a weekend, a blackout, a full workday, exceeds the DELTA 3 Plus's 870Wh usable, while the HomePower 3000's 2,611Wh finishes them all. This is where the matchup is decided.
The scenario table sorts into two piles, and they split on one number: about 870Wh usable in the DELTA 3 Plus. Below that line both units finish. A CPAP night (320Wh) and a tailgate (670Wh) leave the DELTA with margin to spare. Above it, the DELTA quits. A camping weekend wants 2,100Wh and it covers 41% before it is empty. An 8-hour blackout wants 1,645Wh and it manages roughly half. Even a single remote workday at 910Wh trips it, by a hair: 40Wh, one small appliance's worth across the day.
The HomePower 3000 clears all of them with room left, because 2,611Wh usable is a different weight class. The one honest asterisk is at the top end: neither unit is a van-life daily driver. That load runs about 4,685Wh, and the HomePower covers 56% while the DELTA manages 19%. If that is your draw, the answer is not on this page; it is a larger system.
Portability & Form Factor
Selected because: The DELTA 3 Plus's rebuttal is 27 lbs against 59.5. If you carry the unit more than you fill it, weight outranks capacity.
weight
27 lbs against 59.5 is the DELTA 3 Plus's whole rebuttal, and it is a good one. Twenty-seven pounds you lift with one hand and carry across a campsite without a second thought. Fifty-nine and a half is a two-hands, bend-the-knees lift, heavier than a checked bag at the airline limit, and you will plan where it goes before you pick it up.
Give Jackery real credit here: the cell-to-body design makes the HomePower the lightest, most compact 3kWh unit on the market, about a 60-lb one-person carry in a 16.4-inch-wide bodyB1. But lightest-for-3kWh is still more than double the DELTA. If the unit lives in a closet as backup, none of this matters and you would never notice. If it rides to campsites and tailgates most weekends, you will feel every pound of the difference.
Lifetime Value
Selected because: The HomePower 3000 costs $0.10 per lifetime kWh against the DELTA 3 Plus's $0.18, so the larger unit is also the cheaper one to own.
cost / lifetime kWh
The HomePower 3000 costs $0.10 for every kilowatt-hour it will deliver across its life; the DELTA 3 Plus costs $0.18. That gap is not about longevity, because the two are twins there: same 4,000-cycle rating, same 5-year warranty, so they wear out on the same schedule. It is pure capacity math. The HomePower moves 12,288 kWh over its life to the DELTA's 4,096, for 1.67 times the price.
One number cuts the other way, and it is worth defusing before it misleads you. Measured as warranty coverage per dollar, the DELTA looks generous: $144 a year of cover against the HomePower's $240. That is not better terms, though. Both warranties are five years. It is the price gap wearing a disguise. On the metric that actually spends money over a decade, cost per kilowatt-hour, the bigger Jackery is the cheaper unit.
Growth Path
Selected because: The DELTA 3 Plus expands and the HomePower 3000 does not, but the DELTA starts at 1,024Wh, below the HomePower 3000's 3,072Wh, so a first battery buys back capacity you would already have.
solar input
The DELTA 3 Plus expands and the HomePower 3000 does not, and that sounds like the DELTA's ace until you check where it starts. At 1,024Wh, the DELTA sits a third of the way to the HomePower's sealed 3,072Wh. Your first expansion battery mostly buys back capacity the Jackery already ships in the box. The expandability only pulls genuinely ahead once you would cross 3,072Wh, and if that is the plan, you are better off sizing up from the start than stacking boxes.
Here is the honest catch on the unit I am recommending: the HomePower is a sealed box, and what you buy is the ceiling. If you are certain your needs are about to climb past 3kWh, that fixed wall is a real reason to pause, and the DELTA's expansion path is the one card it holds outright. For everyone whose needs sit under 3,072Wh, the sealed unit is the simpler, larger value, and expandability is a feature you would pay to reach a place the Jackery already parks.

Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP sips about 40 watts, so both units run it for nights on end rather than a single evening. The DELTA 3 Plus keeps 550Wh in reserve here, the HomePower 3000 a cavernous 2,291Wh, and neither margin will ever be tested by a breathing machine. With capacity a non-issue, the tiebreak is the wallet and the carry. The DELTA is hundreds less up front and less than half the weight, and for a box that sits by the bed and sips power all night, that is the one to reach for.

The DELTA 3 Plus comes up just short — it needs 910Wh and has 870Wh usable, a 40Wh gap (its nameplate 1,024Wh actually clears this — the flat 15% conversion allowance is what tips it under). Trim that much — one small appliance's worth across the day — and it finishes. The HomePower 3000 covers it outright with 1,701Wh to spare.

Conclusion
August 30, 2026
Verdict: the HomePower 3000, on Power Score margin
Buy the HomePower 3000 if your loads ever run past what a 1,024Wh box holds, which covers most people who camp a weekend, plan for a blackout, or want real home backup. It carries three times the DELTA 3 Plus's capacity for 1.67 times the price ($1,399 vs $719), so it is also the cheaper unit per kilowatt-hour, and it is the only one of the two that finishes a weekend, a blackout night, or a full remote workday. The DELTA 3 Plus wins a narrower brief: light loads you carry often. At 27 lbs against 59.5 and $680 less up front, it is the smarter buy for a CPAP-and-phones user who would never touch the Jackery's extra capacity. Match the unit to your real draw. Sustained or heavy, take the Jackery; light and mobile, take the EcoFlow.

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 3 Plus rates 4.2/5 (54th percentile of 27 Everyday-class units), and HomePower 3000 rates 4.7/5 (84th percentile of 26 Large-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
HomePower 3000: Fixed Capacity
The HomePower 3000 is sealed at 3,072Wh — a complete unit, and already larger than the DELTA 3 Plus's 1,024Wh. By contrast the DELTA 3 Plus can add expansion batteries, but that only pulls ahead if you'd grow past 3,072Wh.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The DELTA 3 Plus is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The HomePower 3000 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 HomePower 3000's figure is a maximum rather than a guarantee — it depends 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 3 Plus works out at 7 years of cover per $1,000 spent against the HomePower 3000's 3.6, but that spread is the price gap, not the terms.

Analyst note
The DELTA 3 Plus is cheaper to buy, but the HomePower 3000 is cheaper to own. At $0.11/kWh over its lifetime vs $0.18/kWh, the HomePower 3000'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 4,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.

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
Don't read the DELTA 3 Plus's expandability as a straight win here: it starts at 1,024Wh, below the HomePower 3000's 3,072Wh, so a first expansion battery largely buys back capacity the HomePower 3000 already includes. It only pulls ahead if you'd grow past 3,072Wh — short of that, the HomePower 3000's larger fixed capacity is the simpler value.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 Plus
The DELTA 3 Plus earns solid reviewer coverage, and one theme dominates it: fan behaviorA0. Marketed as near-silent, the unit's fans actually kick on even at low load and cycle on and off erratically, which undercuts its pitch as a quiet UPSA1. It is not only a noise annoyance. Because the fans do not run steadily, reviewers flag a higher overheating risk when it is pushing heavy loadsA2. The saving grace is that this reads like a firmware problem, and reviewers expect EcoFlow can patch it in software the way it has for earlier unitsA4.
Everything else about it reviews well. The recharge is very fast and the UPS switchover is clean at its rated sub-10ms class, which is the part buyers consistently praiseA3.
“Otherwise well-designed, with very fast recharge times and a seamless sub-10ms UPS switchover for uninterrupted power.”

Jackery HomePower 3000
The HomePower 3000's reputation is built on carrying a lot in a small, light package. Reviewers call it the lightest and smallest 3kWh station going, a roughly 60-lb one-person carry in a 16.4-inch-wide body thanks to its cell-to-body constructionB1. In backup testing it kept a standard fridge running for nearly two days and a 55-inch TV for about 30 hours, with a grid-to-battery switchover measured under its rated 20msB4. Jackery also posts the lowest reported failure and warranty-claim rate among the major brands in owner communities, which is the kind of quiet reliability that matters most when the thing is your blackout planB2.
One note on longevity, held at arm's length: some reviewers rate these LFP cells around 4,000 cycles for their thermal stability, but we could not confirm that particular source is describing this exact model, so treat it as character rather than a hard specB3B0.
“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.”

Who Should Buy Which
Buy the DELTA 3 Plus if you…
- →The CPAP-and-phones buyer. If your overnight draw is a CPAP (about 320Wh) plus some device charging, the DELTA 3 Plus covers it with 550Wh to spare and you would never reach into the HomePower's larger reserve. Save the $680 and the 32 pounds.
- →Anyone who carries the unit more than they drain it. Car camping, tailgates, hauling it room to room during an outage: 27 lbs is a one-hand lift, and portability is the entire reason to prefer the smaller box.
- →Desk-backup buyers who want the tighter UPS. The DELTA is rated at a switchover of no worse than 10ms against the HomePower's 20ms, so a desktop with unsaved work has a little more margin to ride through a cut.
Buy the HomePower 3000 if you…
- →Weekend campers and blackout planners. Anything that runs past about 870Wh in a session, a 2,100Wh camping weekend or a 1,645Wh blackout night, is a job the DELTA cannot finish and the HomePower can, with 500-plus watt-hours left over.
- →Home-backup buyers who want to run bigger things. The HomePower's 3,600W output starts and holds appliances the DELTA's 1,800W cannot, and at $0.10 per lifetime kWh the energy is cheaper over the years you will own it.
- →Value buyers who will actually use the capacity. At $0.39 per Wh against the DELTA's $0.70, every watt-hour you genuinely use is one you bought at a discount, so long as you use more than about a third of it.
If neither fits
If your real need is van-life-scale daily living, roughly 4,685Wh a day, skip both. The HomePower covers 56% of that and the DELTA 19%, so you would be nursing either one to empty every day. Look at a 5kWh-plus system or a platform with true battery expansion instead.
The Bottom Line
Take the HomePower 3000 if your loads ever cross what a 1,024Wh box can hold, which is true for most people who camp a weekend, plan for a blackout, or want real home backup. It finishes the jobs the DELTA 3 Plus quits partway through, and it does it while costing less per kilowatt-hour, so the bigger unit is also the cheaper one to own. Its expandable rival cannot close that with a battery add-on, because the DELTA starts a third of the way back.
But size the unit to your real draw, not to the spec sheet. If you are running a CPAP and charging phones and you carry the thing more often than you fill it, the DELTA is half the weight and hundreds less, and every watt-hour of the Jackery's lead is reserve you would never touch. Sustained or heavy, take the Jackery. Light and mobile, take the EcoFlow. The rare wrong answer here is buying more box than your loads will ever ask for.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Jackery HomePower 3000 worth $680 more than the EcoFlow DELTA 3 Plus?
If you will use the capacity, yes. The HomePower carries three times the energy (3,072Wh vs 1,024Wh) for 1.67 times the price, which makes it cheaper per kilowatt-hour, $0.10 against $0.18 over its life. If your loads are light and you carry the unit often, the extra capacity is money and weight you will not put to work, and the DELTA is the smarter buy.
Can the EcoFlow DELTA 3 Plus run a house through a blackout?
For light essentials overnight, yes. For a typical 8-hour blackout load of about 1,645Wh, it comes up roughly 775Wh short, a little over half the night, because it holds only about 870Wh usable. The HomePower 3000's 2,611Wh usable covers the same night with 966Wh to spare.
Does the DELTA 3 Plus's expandability make it the better long-term buy?
Not against this rival. The DELTA starts at 1,024Wh, so a first expansion battery mostly catches up to the HomePower 3000's 3,072Wh rather than passing it. Expansion only pays off once you would grow past 3kWh, and short of that the HomePower's larger fixed capacity is the simpler value.
Which is quieter for a CPAP at the bedside?
Both list the same 30 dBA floor, so on paper it is a wash. In practice, reviewers flag the DELTA 3 Plus's fans cycling on and off even at low load, which is exactly what someone sleeping two feet away would notice. If bedside silence is the priority, that behavior counts against the DELTA despite the matching number.
How much does the weight difference actually matter?
Only if you move it, but then a lot. The DELTA 3 Plus is 27 lbs, a one-hand carry. The HomePower 3000 is 59.5 lbs, a two-hands lift heavier than a maxed checked bag. For a unit that lives in a closet as backup it is irrelevant; for one that rides to campsites it is the difference you will feel most.
