EcoFlow DELTA 3 Ultra vs Jackery HomePower 3600 Plus
The $500 between these two buys 200W more solar funnel and a ceiling you can raise later, and if you'll use neither, the cheaper box does everything the expensive one does.

Spec deltas
Both of these put out 3,600W continuous and 7,200W of surge, and both sit at 30 dBA. There is no appliance one will start and the other won't, and no room where one is the quiet one. That matters more than it sounds, because it means everything the spec table disagrees about happens at the edges: how fast the sun refills the box, how far the box can grow, and how long the cells last.
The Ultra is $1,399 and the HomePower 3600 Plus is $1,899. That $500 buys 512Wh of extra capacity, 2,000 extra cycles, an expansion port, and a solar input of 1,000W against the Ultra's 800W. It costs you five pounds of weight and ten extra milliseconds of transfer time when the grid drops.
Take the Ultra. Three of those four advantages are conditional: the solar ceiling needs an array you may not own, the cycles land after year eleven of daily use against a five-year warranty, and the expansion port only matters if your load is heading somewhere 3,072Wh can't follow. The fourth, the capacity, is unconditional and it's also the smallest. If any of those conditions is actually you, pay the $500 and don't feel bad about it.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
solar input
That gap only becomes the deciding number when the daily load is bigger than the box, and the van-life profile is exactly that case. At 4,685Wh a day neither unit gets through on one charge, so the question stops being how much you stored last night and becomes how much you can put back before dark. The HomePower puts it back at 1,000W against the Ultra's 800W — a quarter more per hour of sun, not a different answer — and both are capped there no matter how many panels you own.
The DELTA 3 Ultra accepts 800W of solar input; the HomePower 3600 Plus accepts 1,000WCapacities are 3,072Wh and 3,584WhThe van-life profile draws 4,685Wh a day, which is 179% of the Ultra's usable energy and 154% of the HomePower's
Why it mattersIf you're living off this thing on solar every day, the input number is worth a quarter more per hour of sun, 1,000W against 800W — real, but not enough to spend the $500 on by itself.
Capacity
512Wh is a CPAP night with change left over, since a night costs 320Wh. Every load profile on this page that the HomePower survives, the Ultra survives as well, and the one that kills the HomePower kills the Ultra too. Capacity is the loudest number on the spec table and the one that changes the fewest evenings.

Why it mattersIf your loads live inside the profiles on this page, treat the capacity gap as noise and the $500 as real.
rated cycles
Both warranties expire at year five, which puts those extra 2,000 cycles six years past the last day anyone promised you anything. And that's the daily-cycling case, which is the friendliest possible reading for the HomePower. Almost nobody cycles a 3.6kWh box every day. Most of them sit charged, waiting for weather.
4,000 cycles against 6,000$0.11 against $0.08 per lifetime kilowatt-hourBoth units carry a five-year warrantyCycled daily, that's 11 years against 16.4
Why it mattersDaily off-grid cycling is the one use where the cheaper decade turns into money; weekend and standby buyers can ignore the cycle column entirely.
A fridge compressor will never notice 20ms. A desktop power supply on a thin hold-up capacitor might, and a NAS mid-write certainly could. That desk-side job happens to be the one the Ultra has actually been tested doing, with a full workstation day that ended at 40% and a wall-unplug that produced nothing at allA5A6A8.

Why it mattersIf this box's real job is sitting under a desk keeping a workstation alive through a flicker, take the Ultra on transfer speed before price even enters the argument.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: the $500 price gap is the entire argument here, and this is where the HomePower earns some of it back at 8 cents per lifetime kilowatt-hour against the Ultra's 11.
cost / lifetime kWh
Eight cents a lifetime kilowatt-hour against eleven. The HomePower wins that outright, and the reason underneath it is bigger than the two cents suggest: 21,504 lifetime kilowatt-hours against 12,288, which is 75% more energy for 31% more money. As a trade on paper it's a good one.
Now look at the row underneath. Cost per warranty year is $260 for the Ultra and $340 for the HomePower, and the warranty is the only stretch of time where the manufacturer's promise actually applies. Inside those five years you're paying $80 a year extra for energy that arrives after the Ultra's eleventh year of daily cycling. That's a real purchase for someone running off-grid every day and a theoretical one for everybody else.
Growth Path
Selected because: the DELTA 3 Ultra is sealed at 3,072Wh and the HomePower isn't, which is the one difference between them you can't buy your way out of after the fact.
solar input
The Ultra is a sealed box at 3,072Wh, with no expansion port and no upgrade path shorter than buying a second unit. The HomePower takes Jackery expansion batteries, so its 3,584Wh is a floor rather than a ceiling, and reviewers describe it scaling to a genuinely large bankB4.
Whether that's worth $500 is a question about your next two years, not this one. The van-life profile is where it stops being abstract: that day defeats both of these, at 179% of the Ultra's usable energy and 154% of the HomePower's. The Ultra's only answer is a second Ultra. The HomePower's answer is a battery you bolt on. If you can see your loads heading that way, this is the whole reason to pay more, and it's the one thing on this page you can't add later.
Your Life, Your Pick
Selected because: on five of the six load profiles both units finish with charge in reserve, and the sixth defeats them both, which is the strongest evidence that price should decide this.
Five of six profiles end with both boxes still holding charge, and the closest of the five still leaves the Ultra a fifth of a tank. There is no load on this page that one of these handles and the other refuses. The only profile that separates them is the one neither survives.
Reviewer testing lands in the same placeA7A8. An eight-hour remote workday on the Ultra driving a laptop, a desktop workstation and monitors finished with 40% leftA8, and a 300 to 600W creative load ran a little over four and a half hoursA7. Both are heavier than the 910Wh this page budgets for a workday, and the Ultra still came home with room. What actually beats these units is the van-life day, and it beats them both.
What the Specs Don't Tell You
Selected because: four flags fire on this pair and only one of them, the Ultra's fixed capacity, should change anyone's mind.
rated cycles
Only one of the four flags on this pair should change your mind, and it points squarely at the unit I'm recommending. Five pounds of weight difference decides nothing when the lighter of the two is still a bent-knees, both-hands, don't-do-the-stairs-alone lift. Transfer speed and cycle life are real gaps that almost nobody will ever notice in practice.
Fixed capacity is the one that can bite. What you buy in the Ultra is the ceiling, permanently, and that's worth sitting with for a minute before you pocket the $500. If 3,072Wh covers what you're powering, sealed reads as finished rather than limited, and there are fewer connectors in the system to fail. If it doesn't cover you, no price advantage repairs that.
Brand Trust
Selected because: neither company's warranty support is a selling point, which makes where you buy it more consequential than which badge is on the front.
Neither company's support is a reason to pick it. EcoFlow's runs hot and cold: some claims come back with a prepaid label and a fast replacement, others turn into long waits and a refurbished unit against a new-product claim. Jackery's is worse on the same axes, with receipt requirements strict enough to matter and first-line responses that read as scripted. The workaround is identical for both, and it's good advice: buy from Costco or Amazon and let the retailer's return window be your real warranty.
Where they genuinely differ is software and shelf space. EcoFlow's app sits at 4.6 on iOS and 4.2 on Android against Jackery's 2.3 to 3.3, and there are roughly 31,000 people in EcoFlow's subreddit to ask when something behaves oddly, against about 2,000 in Jackery's. Jackery's counterweight is that you can buy it at Costco, Home Depot or Best Buy. One brand gives you a better app. The other gives you somewhere to take it back.

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
The HomePower takes this one on margin, spending 69% of its usable energy against the Ultra's 80% for the same 2,100Wh weekend. Both finish the trip, and both come home to a wall outlet. If the only lifting is out of the trunk and back in again, 80% used is a comfortable number rather than a warning.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Either unit
Both get through the evening and neither breaks a sweat. The Ultra spends 63% of its usable energy on this load, the HomePower 54%, and both are still holding better than a third when the lights come back. It's a dead heat, so break it on the money: identical evening, $500 apart.

SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
This one is over before it starts. A night costs the Ultra 12% of its usable energy and the HomePower 11%, so capacity has nothing to say here. Both are rated at 30 dBA, which is the number that actually matters when the box is a few feet from your pillow. Two units, one outcome, and one of them is $500 cheaper.
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
910Wh of laptop, monitor and router costs the Ultra 35% of its usable energy and the HomePower 30%. Both do the day and most of a second one, so on capacity it's a tie. The tiebreak is the flicker: the Ultra transfers in 10ms against the HomePower's 20ms, which is the difference between a desktop that never notices and one that might.
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 game day easily. Since capacity isn't the deciding factor, weight is: at 72.1 lbs the DELTA 3 Ultra is the one you'll be glad you brought. Fan noise under load is worth a listen too — it's audible in the lulls between songs.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither of these covers a full van-life day. 4,685Wh comes to 179% of the Ultra's usable energy and 154% of the HomePower's, so both are empty before dark with the load still running. What separates them is the fix: the HomePower takes expansion batteries, the Ultra is sealed. If this profile is your actual life, buy the one that can grow, or skip both and start with a system sized for the draw.

Conclusion
August 2, 2026
Verdict: the DELTA 3 Ultra
Take the DELTA 3 Ultra and keep the $500, unless one of three things is true about you: you own panels that push past 800W toward the Jackery's 1,000W ceiling, you'll cycle the battery close to daily for over a decade, or you can see your capacity needs climbing past 3,072Wh. The HomePower 3600 Plus is the better machine on paper, with more capacity, more cycles, 200W more solar input and a port to grow through, and it genuinely costs less per lifetime kilowatt-hour. But every one of those wins needs a condition to cash: panels you have to buy, years that land past the warranty, or a load you don't have yet. The Ultra answers with $500, five pounds, and a faster transfer, and it clears every load profile on this page that the HomePower clears. Buying a box, buy the cheaper one. Building a system, pay the $500.

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 Ultra rates 4.7/5 (80th percentile of 26 Large-class units), and HomePower 3600 Plus rates 4.1/5 (47th percentile of 16 Home Backup-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Five Pounds Apart, Both Two-Handed
The DELTA 3 Ultra is 72.1 lb and the HomePower 3600 Plus is 77.2. Five pounds settles nothing. What settles something is that the lighter of the two is still 72 pounds, which means bent knees, both hands, and a firm no on carrying it down basement stairs by yourself. Decide where it's going to live before you buy it, because it isn't going to move much afterward.
The DELTA 3 Ultra Is Sealed at 3,072Wh
There's no expansion port on the Ultra. What you buy is the ceiling, and outgrowing it means buying a second unit rather than adding a battery. That's the strongest single reason on this page to spend the extra $500 on the HomePower, which grows past its 3,584Wh with Jackery expansion batteries. It only bites if you'll actually grow. If 3,072Wh covers your loads, a sealed system is a complete one, with fewer connectors to go wrong.
10ms Line-Interactive vs 20ms Standby
The Ultra switches over in 10ms, the HomePower in 20ms. A fridge compressor will never know the difference. A desktop power supply on a thin hold-up capacitor might, and a NAS in the middle of a write certainly could. If this unit's day job is under a desk keeping a workstation alive through a flicker, the faster transfer is a real feature. For a fridge and some lamps, both sit comfortably inside the window.
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 Ultra works out at 3.6 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.
The Cycles You'll Actually Reach
4,000 cycles against 6,000, and the honest question is which of those numbers you will ever see. Cycle either one every single day and the horizons are 11 years and 16.4. Cycle it on weekends, which is what nearly all of these end up doing, and they're 38.5 years and 57.7, at which point you're comparing the battery to the house it's sitting in. Buy on cycle life only if you know you're the daily-cycling exception.

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
DELTA 3 Ultra
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 800W of solar. Suitable for a 1-2 panel setup.
Generous port selection supports complex multi-device setups.
HomePower 3600 Plus
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 1,000W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.
Expansion batteries are Jackery-specific. You're investing in the Jackery ecosystem.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
The DELTA 3 Ultra is sealed at 3,072Wh, which is fine if that covers you. The HomePower 3600 Plus starts at 3,584Wh and can grow beyond it with Jackery expansion batteries — real headroom the DELTA 3 Ultra 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
The field record on the Ultra is thin, and what exists is professional testing rather than owners a year in, so weight it accordinglyA1A5A9. What that testing agrees on: it stays quiet even with the inverter pushed hard, and it's clearly quieter than older EcoFlow unitsA1A2. Transfer behaviour is the other consistent finding. Pull the wall plug mid-session and nothing dips or shuts down, which is the APC-style behaviour people expect from a UPS and rarely get from a power stationA4A5A6. Build quality reads as premium down to the sliding covers over the rear input portsA9A15.
The complaints are small and specific. One reviewer couldn't read the display in direct sun without cupping their hands over itA11. Another noticed that when you overload the unit, the 30A port is the first thing it dropsA3, which is worth knowing if that port is feeding something you'd rather not lose first. Nothing structural has surfaced, which is less reassuring than it sounds when the whole record is bench workA7A8.

Jackery HomePower 3600 Plus
One owner rode out a three-day regional blackout on the HomePower, running a fridge, a microwave, string lights, fans and a CPAP for two straight days on a single chargeB3. That's one account rather than a pattern, but it's the account you'd want. The recurring praise across the coverage is consistent and unexciting in the best way: EV-grade cells rated for 6,000 cycles, weight that stays manageable for a 3.6kWh unit thanks to built-in wheels and a pull handle, and quiet, uneventful operationB1B2B4. It holds 4.5 out of 5 on AmazonB4.

Who Should Buy Which
Buy the DELTA 3 Ultra if you…
- →You're buying a blackout box for a house that's on the grid: fridge, a few lamps, the router, phones, maybe a furnace fan for an evening. The Ultra covers that night comfortably and costs $500 less to do it.
- →Your power station is going to live under a desk as a UPS. The 10ms transfer, a wall-unplug that produced no dips at allA5A6, and a full workstation day that ended with 40% leftA8 is the exact profile you're shopping for.
- →You charge from the wall, or from a modest panel setup. If your array is 800W or smaller, both of these refill at exactly the same speed and the HomePower's extra input is a ceiling you'll never touch.
Buy the HomePower 3600 Plus if you…
- →You already own serious solar. At 1,000W of input the HomePower refills in about 3.6 hours of good sun against the Ultra's just-under-four, and that small edge repeats every day of a long outage.
- →You're building toward partial-home backup rather than buying a box. 3,584Wh is a starting point with a port on it. 3,072Wh is a finish line.
- →You'll cycle it close to daily for a decade or more. 6,000 cycles at 8 cents a lifetime kilowatt-hour is the one scenario where the extra $500 comes back with interest.
If neither fits
If your daily draw looks like the van-life profile, neither of these gets you through a day on one charge, and buying either one first means buying twice. Start with a system sized above that daily draw, or a modular setup you can stack from day one. At the other end: if your heaviest night is a CPAP, a laptop and a few phones, both of these are two tiers more battery than you need. The lightest profile on this page, a tailgate at 670Wh, still only costs the Ultra 26% of its usable energy. Shop the 1kWh class and keep the difference.
The Bottom Line
Take the DELTA 3 Ultra. Same 3,600W, same 7,200W of surge, same 30 dBA, and it clears every load profile on this page that the HomePower clears. The $500 you don't spend is the most certain number in this comparison. Everything it would have bought is contingent on a solar array, a decade of daily cycling, or a capacity need you don't have yet.
If one of those contingencies is genuinely you, the HomePower is worth every dollar and you should stop reading and go buy it. That's a fork, not a hedge. The question underneath it is whether you're buying a box or building a system. Buying a box, buy the cheaper one.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Jackery HomePower 3600 Plus worth $500 more than the EcoFlow DELTA 3 Ultra?
Only if you'll actually use one of the three things it buys: 1,000W of solar input, the expansion port, or 6,000 cycles instead of 4,000. If you charge from a wall outlet, if 3,072Wh covers your loads, and if you won't be cycling it every day for more than a decade, that $500 is buying you 512Wh and not much else. Both units put out 3,600W continuous and 7,200W of surge, so there's no appliance one starts and the other won't.
How much solar can the EcoFlow DELTA 3 Ultra actually take?
800W, and that's a hard ceiling no matter how many panels you connect. From empty that's 3,072Wh divided by 800W, just under four hours of strong, unclouded input for a full refill. The HomePower 3600 Plus takes 1,000W and needs about 3.6 hours for its larger 3,584Wh. If you refill from the sun daily that difference is small; if you refill from a wall outlet overnight it never shows up.
Can either of these run a house during a blackout?
Part of one, for an evening. The eight-hour blackout profile on this page draws 1,645Wh (fridge, lights, router, phones, a fan), which is 63% of the Ultra's usable energy and 54% of the HomePower's, so both finish with room. What neither does is a full day of whole-home load: at the van-life draw both come up short, the Ultra by more than the HomePower, but neither one finishing the day.
Which one is better for a CPAP?
Either. A night costs 12% of the Ultra's usable energy and 11% of the HomePower's, so a full charge is about eight nights on the Ultra and nine on the HomePower, and you'll never approach either number. Both are rated at 30 dBA, which is the spec that matters when the unit is a few feet from your head at 3 a.m. Buy on price, which means the Ultra.
Does the EcoFlow DELTA 3 Ultra expand?
No. It's sealed at 3,072Wh with no expansion port, and the only way to add capacity is to buy a second unit. The HomePower 3600 Plus does accept Jackery expansion batteries beyond its 3,584Wh, which is the single structural advantage it holds here. Whether that counts against the Ultra depends entirely on whether 3,072Wh covers what you're powering: if it does, a sealed system is a complete one rather than a limited one.
