Spec deltas
The DELTA 3 Plus comes up 40Wh short of a standard remote workday: 910Wh wanted, 870Wh usable once the inverter and a sane depth of discharge take their 15%. Everything else on this page is a consequence of that gap.
The HomePower 3600 Plus costs $1,180 more and holds 3,584Wh against 1,024Wh, which reads like a straightforward pay-more-get-more trade until you check the running cost. Six thousand cycles at 3,584Wh is 21,504 kWh over its rated life for $1,899, or 8 cents a kilowatt-hour. The DELTA 3 Plus manages 4,096 kWh from 4,000 cycles and lands at 17. The expensive box is the cheap one to own.
What the Jackery takes from you is mobility, and it takes a lot of it. 77.2 lbs against 27 is not a nuance on a scale, it's the difference between a unit you take places and a unit you choose a corner for. If your power problem has an address, that's a fine trade. If it moves, the arithmetic changes and the DELTA 3 Plus earns its keep.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
A clear mismatch you catch in the store. A 40Wh mismatch you catch at 4pm on a Thursday with the monitor going dark, and the fix is either a wall socket you were trying to do without or a second purchase. The Jackery does the identical day and still has 2,136Wh in hand, which means the workday never becomes a thing you think about.
DELTA 3 Plus: 1,024Wh nameplate, 870Wh usable after the 85% derateRemote Workday load: 910Wh needed, DELTA 3 Plus short by 40WhHomePower 3600 Plus finishes the same day at 30% of its 3,046Wh usable
Why it mattersIf your desk is a laptop plus a monitor plus anything else at all, the 1,024Wh unit is the wrong size rather than the thrifty size.
rated cycles
That works out at 8 cents a lifetime kilowatt-hour against 17, and the warranty term is identical on both, so the extra $1,180 buys you cells and nothing else. It is not buying better coverage, longer support, or a safety net the cheaper unit lacks. It is buying energy, which is the only thing on this page that can't be added later without buying another box.
HomePower 3600 Plus: $1,899, 3,584Wh, 6,000 cyclesDELTA 3 Plus: $719, 1,024Wh, 4,000 cyclesBoth units carry a 5-year warranty
Why it mattersAnyone who will genuinely cycle the unit, weekly outages or daily off-grid use, should stop reading the price tag and read the cycle count.
The trap is that this lands on the DELTA 3 Plus's best feature. A 10ms switchover is bought by people who leave the unit plugged in permanently under a desk or beside a bed, which is precisely the duty where erratic fan cycling is hardest to live withA1A2. The spec that recommends it and the flaw that undermines it describe the same use case.
Both units publish the same 30 dBA noise figureReviewers report the DELTA 3 Plus's fans activate at low load and cycle on and off erraticallyA1A2, with firmware named as a possible fixA4DELTA 3 Plus switches over in 10ms against the HomePower 3600 Plus's 20ms
Why it mattersIf you want an always-on UPS in a room you occupy, weight the fan reports above the switchover number, or wait to see whether the firmware fix arrivesA4.
weight
None of which rescues it, because the DELTA 3 Plus is short of the camping weekend by 1,230Wh, more than its entire usable capacity of 870. Being light and quick to refill only helps a unit that finishes the trip. This one asks you to find a wall halfway through it.
DELTA 3 Plus: 27 lbs, up to 1,000W solar into a 1,024Wh battery, about an hour of rated sun to refillHomePower 3600 Plus: 77.2 lbs, up to 1,000W solar into 3,584Wh, about 3.6 hoursWeekend Camping load is 2,100Wh; the DELTA 3 Plus is 1,230Wh short
Why it mattersPick on the load first. Weight and recharge speed only break ties between two units that both make it to the end.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: 870 usable watt-hours against 3,046 is the number that settles four of the six loads modelled below.
continuous output
870 watt-hours is what the DELTA 3 Plus actually hands you: 1,024Wh on the label, less the 15% that the inverter and a sensible depth of discharge take back. The HomePower 3600 Plus hands you 3,046Wh on the same arithmetic. Every downstream question on this page is already answered by that ratio.
The useful way to hold it is in evenings. The EcoFlow covers one, and the Jackery covers a night plus most of the next one. Four of the six loads modelled here sit above 870Wh, which says less about the DELTA 3 Plus being weak than about what people actually plug into these things once they own one.
Portability & Form Factor
Selected because: 27 lbs against 77.2 is the only column the DELTA 3 Plus takes, and for some buyers it's the only one that counts.
weight
27 lbs and 77.2 lbs are different categories of object rather than different points on a scale. One rides in a trunk and comes inside with you. The other you set down somewhere sensible and leave, and you'll resent every time you change your mind about where sensible was.
Worth checking before echoing any of that, because home-backup gear is often a multi-box installation where the published weight is a sum and lifting never happens: it isn't here. The 77.2 lbs is a single chassis, and reviewers describe built-in wheels and a pull handle carrying the load on flat groundB2. So this is an honest heavy portable, not a commissioned system. Flat ground is fine. The lift into a car and the flight of basement stairs are the two moments that cost you, and no amount of wheels helps with either.
Lifetime Value
Selected because: Spread across their rated cycles, the $1,899 unit delivers energy at 8 cents a kilowatt-hour and the $719 one at 17.
cost / lifetime kWh
The $1,899 unit is the cheaper one. Six thousand cycles at 3,584Wh is 21,504 kWh across its rated life, putting its energy at 8 cents a kilowatt-hour, while the DELTA 3 Plus gets 4,096 kWh from 4,000 cycles at 1,024Wh and lands at 17. Both carry the same 5-year warranty, so the extra $1,180 is not buying better terms.
Per watt-hour of capacity it's the same story: $1,899 over 3,584Wh is 45 cents, $719 over 1,024Wh is 67. The Jackery is the cheaper unit on every measure except the one printed on the box. What it is not, ever, is the smaller one.
Your Life, Your Pick
Selected because: Six modelled loads, and the one to stare at is the workday the DELTA 3 Plus misses by 40Wh.
Read the scoreboard with one correction. The HomePower 3600 Plus takes four of the six loads and ties the CPAP night, but two of those wins are Weekend Camping and a Tailgate Party, and the scoring counts watt-hours without ever counting the 77.2 lbs you'd be wheeling to the site. On a 670Wh tailgate both units finish the day; the Jackery's win there is 2,376Wh of reserve you brought along and didn't touch. Treat those two results as capacity findings, not as advice about what to load into the car.
The scenario that deserves your attention is the Remote Workday, where the gap is about 4% and the DELTA 3 Plus is the one on the wrong side of it. That's the failure you can't spot in a showroom, because catching it would mean modelling your own desk to within a few percent before you bought anything. The blackout result is the blunt one and the workday result is the instructive one.
Brand Trust
Selected because: Identical 5-year warranties, so the brand question reduces to the app and the support desk behind it.
Identical 5-year warranties, so the brand question is really about the years when you're not claiming. EcoFlow's app sits at 4.6 on iOS across roughly 8,400 ratings and 4.2 on Android across roughly 17,000. Jackery's runs 2.3 to 3.3, is split across two separate apps, and asks you to sign in even when you're standing next to the unit. On a box whose whole job is to be checked on during an outage, that gap has a price.
Neither support desk is a selling point, and both brand profiles arrive at the same practical workaround: buy from Costco or Amazon so a retailer's return window sits in front of the warranty claim. Follow that with either unit. EcoFlow also brings the larger ecosystem and a Reddit community of around 31,000 against Jackery's 2,000, which matters mostly on the evening you're trying to work out why something won't charge.

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
HomePower 3600 Plus
A 2,100Wh weekend is more than the DELTA 3 Plus holds. It has 870Wh usable and finishes 1,230Wh short, which is to say it comes up short by more than its entire tank. The HomePower 3600 Plus covers the weekend on 69% of its 3,046Wh usable and keeps 946Wh in reserve. The cost this scoreboard doesn't charge it for: 77.2 lbs, and campsites are not parking lots.

LOAD Phone Charger 15W×6h · LED Lights 40W×8h · Box Fan 75W×14h · CPAP Machine 40W×16h
SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
HomePower 3600 Plus
Eight hours of a modelled 1,645Wh outage leaves the DELTA 3 Plus 775Wh short, so it covers a little over half the night and then you're looking for candles. The HomePower 3600 Plus finishes at 54% of usable and still holds 1,401Wh, which is most of another night but not quite all of one. This is the scenario the price gap exists to buy.
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
320Wh is a rounding error for both of these. The DELTA 3 Plus ends the night with 550Wh of its 870 untouched, the HomePower 3600 Plus with 2,726Wh of its 3,046. Both publish the same 30 dBA, so the figure that usually decides a bedside unit decides nothing here and shouldn't be used as a tiebreak. What does decide it is $719 against $1,899. Buying 3,584Wh to draw 320 of it is a decision about your other loads, not about your CPAP.
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
HomePower 3600 Plus
Forty watt-hours. The DELTA 3 Plus wants 910Wh for the day and carries 870 usable, so it stops about 4% from the finish. Near misses are worse than clear ones, because a clear one sends you to a bigger unit and a near one sends you home confident. The HomePower 3600 Plus does the same day on 30% of its usable capacity and keeps 2,136Wh.
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
HomePower 3600 Plus
Both finish the game. The DELTA 3 Plus spends 77% of its usable 870Wh on the 670Wh load and ends with 200Wh; the HomePower 3600 Plus spends 22% and ends with 2,376Wh, which is why it takes the scenario. Worth being clear about what that reserve costs in a parking lot, though: you're moving 77.2 lbs across it instead of 27. If the load really is this size, the headroom is insurance you're paying to carry.

Neither unit covers this scenario's 4,685Wh: the DELTA 3 Plus comes up 3,815Wh short (about 19% covered), the HomePower 3600 Plus 1,639Wh (65%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Conclusion
August 9, 2026
Verdict: the HomePower 3600 Plus, on Power Score margin
Take the HomePower 3600 Plus. It covers every load on this page that can be covered, including a 1,645Wh eight-hour outage at 54% of its usable energy and a 2,100Wh camping weekend at 69%, while the DELTA 3 Plus falls short on four of the six, including a remote workday it misses by 40Wh. It does that at 8 cents per lifetime kilowatt-hour against 17, under the identical 5-year warranty, with 6,000 rated cycles to the EcoFlow's 4,000. The DELTA 3 Plus is not a weak unit, it's a smaller one, and it's $719 against $1,899. Buy it instead only if you know your ceiling sits under 870Wh in a sitting and you'll be carrying it, because 27 lbs against 77.2 is the one column it takes and it takes that one decisively.

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 3 Plus rates 4.2/5 (54th percentile of 27 Everyday-class units), and HomePower 3600 Plus rates 4.1/5 (47th percentile of 16 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.
77.2 lbs Decides Where It Lives, Not Whether You Take It
77.2 lbs is a two-hands lift over a tailgate and a bad idea on stairs, and this is a single chassis rather than a multi-box install, so the number is the number. In practice you pick a spot for the HomePower 3600 Plus and it stays there: beside the panel, in the garage, under the desk. The DELTA 3 Plus at 27 lbs is the one that moves between rooms and vehicles without a plan. Work out which of those two behaviours you're actually buying before you compare a single watt-hour.
The Faster UPS Is the Smaller Box
10ms against 20ms, and it's the 1,024Wh portable holding the tighter number rather than the 3,584Wh home-backup unit. Both land inside the window that keeps a desktop, a router or a CPAP running through the handover, so neither is disqualified. But if the reason you're here is that something in the house must never blink, the spec puts the little one in front, which is a peculiar place to arrive when the other one has HomePower written on the case.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The HomePower 3600 Plus'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 3600 Plus's 2.6, but that spread is the price gap, not the terms.
Six Thousand Cycles Against Four Thousand
At daily cycling the HomePower 3600 Plus reaches 16.4 years and the DELTA 3 Plus 11, and both comfortably outrun their shared 5-year warranty. So cycle life here isn't really a durability question, it's an economics one. Spread the purchase price across those cycles and the Jackery's energy costs 8 cents a kilowatt-hour against the EcoFlow's 17. Hitting the cycle limit doesn't kill either battery either, it just leaves it at around 80% of original capacity, still working.
Full record above — the Test Desk pick is the HomePower 3600 Plus.

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.

Unique strength
Fastest-charging technology (X-Stream), deepest product ecosystem, and most active innovation cadence. At the very top of the range, the DELTA Pro Ultra platform stacks batteries and inverters into whole-home backup — a flagship path, not a line-wide feature.
Worth knowing
Two things to file. The October 2025 recall for overheating covered the DELTA Max 2000, a different model, with six reported incidents, and EcoFlow offers no parts or service once the 5-year warranty runs out. It also floated a subscription tier for advanced app features in early 2025 and backed off after the community objected, which is worth remembering as a thing the company was willing to try.
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
The app is the soft spot: 2.3 to 3.3 out of 5 across iOS and Android, split confusingly across a Jackery app and a Jackery Home app, with a mandatory login even when you're offline and standing beside the unit. On a box you mostly leave plugged in, that's an irritation. It's a larger problem if the plan was to watch an outage unfold from your phone.
Analyst note
EcoFlow brings the deeper ecosystem, the far better app and the bigger community; Jackery brings the retail counter, with Costco, Home Depot, Best Buy and Amazon all stocking it. That retail spread is worth more than it sounds, because both brand profiles independently recommend buying through Costco or Amazon so a store return policy sits in front of the warranty desk. That recommendation is not a compliment to either support organisation.

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 has one repeatedly-cited flaw and it isn't on the spec sheet: reviewers report the fans spinning up even under low loads and cycling on and off erratically, which is exactly the behaviour that ruins a unit marketed as a quiet always-on UPSA1A2. One review goes further and frames the quiet as part of the problem, arguing the fans aren't doing their job consistently and that heavy loads carry more heat risk as a resultA2.
The same coverage is warm about everything else, crediting genuinely fast recharging and a switchover clean enough that connected gear doesn't noticeA3, and it points out EcoFlow has fixed this class of behaviour in firmware on other stations after launchA4. That distinction is worth holding onto. A design decision you live with; a software release you wait for.
“Otherwise well-designed, with very fast recharge times and a seamless sub-10ms UPS switchover for uninterrupted power.”

Jackery HomePower 3600 Plus
Coverage of the HomePower 3600 Plus is consistently positive and consistently about the same three things: the 6,000-cycle EV-grade LiFePO4 packB1, the weight being reasonable for a 3.6kWh-class unit with wheels and a pull handle doing most of the movingB2, and a 4.5-out-of-5 Amazon rating where the recurring praise is quiet, uneventful operationB4. Uneventful is the correct compliment for a home-backup box.
One widely repeated story has an owner running a fridge, a microwave, string lights, fans and a CPAP for two straight days on a single charge during a three-day regional outageB3. Read that as a story rather than a spec. The entire usable tank is 3,046Wh, and the account never says whether the sun was topping it up through a 1,000W solar input that would have been happy to.
“EV-grade LiFePO4 battery rated for 6,000 cycles, giving well over a decade of service life.”

Who Should Buy Which
Buy the DELTA 3 Plus if you…
- →Your ceiling is an evening rather than a weekend: laptop, lights, a fan, phones. 870Wh of usable energy covers that with room to spare and you keep $1,180.
- →You actually carry it. 27 lbs is one person and one trip, into a trunk or up stairs without recruiting anybody, and it refills from up to 1,000W of solar, roughly an hour of rated sun against a 1,024Wh battery.
- →You want the tighter UPS of the two for a desk, at 10ms against 20ms. Read the fan reports before you commit to leaving it switched on in a room you sit inA1A2.
Buy the HomePower 3600 Plus if you…
- →You're shopping because the power went out and you didn't care for it. The modelled 1,645Wh eight-hour outage lands at 54% of usable and leaves 1,401Wh, which is most of a second night.
- →You'll cycle it hard. Six thousand rated cycles at daily use is 16.4 years, and the energy costs 8 cents a kilowatt-hour across that life.
- →It gets a permanent home. 77.2 lbs stops being a problem the moment you stop planning to move it, and starts being one the moment you don't.
If neither fits
If your real day looks like the Van Life load on this page, 4,685Wh, close the tab. The DELTA 3 Plus is 3,815Wh short of it and even the HomePower 3600 Plus is 1,639Wh short, so you'd be choosing between two units that both run out before dinner. What you want is a larger station or a wired house battery with serious solar behind it, and picking the better of these two will only cost you the money you'll spend again in six months.
The Bottom Line
Take the HomePower 3600 Plus. The DELTA 3 Plus stops short of an ordinary desk day, and a unit that runs out on a normal Tuesday is the wrong size whatever it costs. Pay the $1,180 and the running cost goes down rather than up: 8 cents a lifetime kilowatt-hour against 17, on the same 5-year warranty and 6,000 cycles against 4,000.
The one honest reason to go the other way is that you'll be picking it up. 77.2 lbs chooses a corner and lives in it, and 27 lbs comes with you. If your power problem has an address, buy the Jackery and stop thinking about it.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the EcoFlow DELTA 3 Plus run my house during a blackout?
Not for a full evening. This page models an eight-hour outage at 1,645Wh, and the DELTA 3 Plus has 870Wh usable, so it stops 775Wh short, a little over halfway. The HomePower 3600 Plus covers the same outage using 54% of its 3,046Wh usable and still holds 1,401Wh. If whole-home backup is why you're shopping, the 1,024Wh unit is the wrong tool rather than a cheaper version of the right one.
Is the Jackery HomePower 3600 Plus too heavy to move around?
It's 77.2 lbs, which is a two-hands lift over a tailgate or up a flight of stairs and a genuine nuisance on soft ground. Reviewers note it has built-in wheels and a pull handle, which makes flat ground easy and does exactly nothing for the moment you lift it into a car. Plan on placing it once and leaving it there.
Which one is the better UPS for a desktop PC or a NAS?
On paper the DELTA 3 Plus, which switches to battery in 10ms against the Jackery's 20ms. There's a catch worth knowing before you slide it under a desk: reviewers report the fans running at low load and cycling erratically, which is the single hardest trait to live with in an always-on unit, and they think firmware could resolve it. If room silence matters more to you than shaving 10ms off the transfer, that tradeoff is real.
Is the HomePower 3600 Plus worth $1,180 more than the DELTA 3 Plus?
If you'll use the capacity, yes, and the running cost actually favours it. Six thousand cycles at 3,584Wh is 21,504 kWh over its life for $1,899, which is 8 cents a kilowatt-hour against the DELTA 3 Plus's 17. If your loads never cross 870Wh in one sitting, no, because then you're paying $1,180 for headroom you'll never reach into.
Do both of these expand, and does expansion change the answer?
Both accept their maker's expansion batteries, so neither one is a dead end. What doesn't separate them is the feed to that larger bank: both take up to 1,000W of solar, so as the bank grows the Jackery has no more input to refill it, and 2,560Wh more to fill to begin with. Capacity you can't recharge quickly is just a heavier version of the same problem.
