EcoFlow DELTA 3 Ultra vs Jackery HomePower 3000
With the same battery, the same inverter and the same $1,299 sticker on both, this comes down to what you can lift and how fast the sun can put it back — and the Jackery wins both.

Spec deltas
You could put these two side by side and shuffle the spec sheets: $1,299 each, 3,072Wh each, 3,600W continuous and 7,200W of surge each, 4,000 cycles, five-year warranties, matching 100W USB-C ports, matching 30 dBA ratings. Even the PowerScores land at 5,072 and 5,162, a 90-point spread no buyer will ever feel. When two boxes agree this thoroughly, the few rows where they disagree stop being footnotes and become the entire comparison.
Three rows refuse to match. The HomePower 3000 weighs 59.52 lb where the DELTA 3 Ultra weighs 72.1, a 12.58 lb difference that decides whether this is a lift you make or a lift you postpone. It accepts 1,400W of solar where the EcoFlow accepts 800W. And it gives up ten milliseconds at the transfer switch, 20ms standby against the DELTA's 10ms line-interactive.
Take the Jackery. The two rows it wins are the two you notice, the weight every time the box moves and the solar every day an outage runs long, while the row it loses only bites on hardware fussy enough to count milliseconds. EcoFlow's real counteroffer isn't hardware at all. It's a much better app and a much larger community behind it, and if you intend to manage this thing from your phone, that's a legitimate reason to spend identical money on the heavier box.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
And there's no deferring it, either: each unit is sealed at 3,072Wh with no add-on battery port, so neither one grows into an advantage two years from now. The decision can't be handed to your wallet and it can't be handed to a future upgrade. It gets made on the three physical rows where these units actually differ: 12.58 lb, 600W of solar input, and ten milliseconds.
Both list at $1,299Both hold 3,072Wh and are rated 4,000 cycles4,000 cycles x 3,072Wh = 12,288 lifetime kWh for each, at $0.11 per lifetime kWhNeither unit takes an add-on battery
Why it mattersIf you're waiting for a sale or a coupon to break this tie, stop waiting. They cost the same to buy and the same to run, so decide it with your hands and your roof.
solar input
That gap only matters once an outage runs past a single day, and the outage that runs past a single day is exactly what people buy 3kWh boxes for. An eight-hour night takes 1,645Wh, which our scenario math puts at 63% of either unit, so on the second morning you're pulling roughly two-thirds of a pack back in before dark. The Jackery finishes that job with the afternoon to spare. The DELTA is still eating daylight it may not get, because panels rarely hit their rated number and clouds don't negotiate.

Why it mattersAnyone whose backup plan involves panels instead of a gas can should take the HomePower; anyone who only ever refills from a wall outlet can ignore this row entirely.
Now add the life of the thing: 4,000 cycles is eleven years of running it down every single day, and neither unit takes an add-on battery, so the box you buy is the box you carry for as long as you own it. Weight on a unit like this isn't a first-week annoyance. It's every closet, every staircase, every load into a truck bed, for a decade. The Jackery's 16.4-inch width also slides onto shelves that turn rivals awayB1, which is the half of portable nobody puts on a spec sheet.
DELTA 3 Ultra: 72.1 lbHomePower 3000: 59.52 lbOne person can carry the Jackery at around 60 lb, and it is 16.4 inches wideB14,000 cycles is 11 years of cycling it daily
Why it mattersIf it lives in one corner of a utility room and never moves, none of this touches you. If it moves at all, the lighter one is the one you'll actually bother to deploy.
So the ten milliseconds only buys you something on hardware that counts them. A desktop workstation, a NAS, a gaming rig whose power supply drops out and takes your open files with it. That is the DELTA 3 Ultra's one clean hardware win here, and for the person protecting an office it outweighs every pound the Jackery saves. For a fridge, a router and a few lamps it's worth precisely nothing.

Why it mattersBuy the DELTA if a desktop is plugged into it. Otherwise the faster transfer is a spec-sheet trophy you'll never cash.
The specific dimensions that decide these two units — everything else is a tie.
Portability & Form Factor
Selected because: 72.1 lb against 59.52 lb is the one difference on this page you feel every single time the unit moves.
weight
Neither of these is a grab-and-go unit, and any page that says otherwise hasn't lifted one. What 59.52 lb buys you over 72.1 is the difference between carrying it to the car yourself and recruiting a second person, and reviewers put the Jackery right at that one-person line at around 60 lbB1. A dozen-odd pounds sounds like nothing until you're taking it up the basement stairs.
The other half of portable is shape. The HomePower is 16.4 inches wide and gets described as the smallest 3kWh station goingB1, which decides whether the plan is a closet shelf and a footwell or a permanent spot in the garage. A unit that doesn't fit where you need it is a unit you talk yourself out of using.
Runtime: Will It Power Your Gear?
Selected because: Identical 3,072Wh packs behind identical 3,600W inverters give identical runtimes, so the live question is refill speed: 1,400W of solar against 800W.
The runtime column is a mirror. Two 3,072Wh packs behind two 3,600W inverters give the same hours at the same loads, and no amount of squinting will separate them. What the table can't show you is that the model's idea of a workday is politer than yours. Our Remote Workday scenario budgets 910Wh, about 35% of the unit, while a reviewer running a laptop, a desktop workstation and monitors off this chassis finished eight hours with 40% leftA8. Call it 60% consumed, close to double the estimate.
That's an argument for buying this capacity class rather than a smaller one, and it's also why refill speed outranks runtime on this particular page. You never get every rated watt-hour back out, nobody runs a pack to zero, and on the second day of an outage the question was never how long it lasted. It's whether the sun can put it back before dark.
Brand Trust
Selected because: With the hardware this evenly matched, the app you open every week and the support queue you land in do more of the deciding than the spec sheet.
The hardware is a coin flip, so the tiebreaker moves to the thing you actually touch every week. EcoFlow's app rates 4.6 on iOS and 4.2 on Android. Jackery's runs 2.3 to 3.3, split across two separate apps that both want you logged in while you're standing next to the unit. If you plan to check state of charge from your phone, that gap is the strongest argument on this page for the DELTA, and it comes free, because the two boxes cost the same. The same lopsidedness shows up in the crowd behind each brand: EcoFlow's subreddit runs about 31K members against roughly 2,000 for Jackery, which is the difference between searching your problem and posting it.
Neither support desk is a selling point. EcoFlow's is polarized enough that the same complaint can end in a prepaid replacement label or in a long wait and a refurbished unit against a new claim. Jackery's is the more consistently criticized of the two, with scripted replies and strict receipt requirements on warranty claims. The fix is identical either way: buy from Costco or Amazon and let the retailer's return window be your real warranty. The counterweight in Jackery's favor is that you're less likely to need the phone number at all, since it carries the lowest reported rate of failures and warranty claims among the major brandsB2.
What the Specs Don't Tell You
Selected because: Both cards that fire here are informational rather than warnings, which is itself the finding: neither unit hands you a dealbreaker.
Two cards fire on this pair and neither one is a warning, which tells you most of what you need to know. The weight card is about the DELTA 3 Ultra's 72.1 lb, and it's filed as information rather than a fault because 72.1 lb is entirely normal for 3,072Wh. It's just not as normal as 59.52. The UPS card is the one that goes the DELTA's way, and it's the only card on the page that does.
Nothing fires for surge headroom, cycle life, warranty or noise, because the two units are identical on all four: 7,200W of surge, 4,000 cycles, five years, 30 dBA. When the only flags a pair can raise are a weight difference and a ten-millisecond transfer time, you're looking at two versions of the same product wearing different badges.

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 2,100Wh weekend lands at 80% of either unit, which is the same answer given twice. So the tiebreak is the walk from the truck: 59.52 lb against 72.1 lb, and only one of those is a lift you'll volunteer for on Sunday as well as Friday.
Battery budget usedlower = more headroom
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
Either unit
An eight-hour outage takes 1,645Wh, 63% of either one, and neither breaks a sweat doing it. What separates them is the morning after. The Jackery takes 1,400W of solar to the DELTA's 800W, so it starts the second night far closer to full, while the DELTA needs most of a good day to catch up.
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
A CPAP asks for 320Wh, about 12% of either battery, and both are rated at 30 dBA, so the box beside the bed stays quiet whichever badge is on it. These two tie so completely here that the honest advice is to decide on some other night's job, because this one won't tell them apart.
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
Both power your workstation all day without strain. At these utilization levels the real difference is USB-C for direct laptop charging — 140W on the DELTA 3 Ultra against 100W — which beats the inverter for convenience and wastes less energy.
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 59.5 lbs the HomePower 3000 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.
Battery budget usedlower = more headroom
LOAD Blender 400W×0.5h · LED TV (55") 80W×4h · Bluetooth Speaker 15W×4h · Phone Charger (×3) 45W×2h
SCN-06 · 24 hours · needs 4,685Wh
Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
A full van-life day wants 4,685Wh, or 179% of what either unit holds, so neither one gets you through it. And neither takes an add-on battery, which means there's no bolting your way out of the shortfall later. This is the scenario where you buy a bigger box, not a better one of this size.

Conclusion
August 2, 2026
Verdict: the HomePower 3000
Take the HomePower 3000. At $1,299 each, with the same 3,072Wh pack, the same 3,600W inverter and 7,200W surge, the same 4,000 cycles and the same five-year warranty, these two cost the same to buy and the same to run: $0.11 per lifetime kilowatt-hour, either way. That leaves three rows to settle it, and the Jackery takes two of them. It weighs 59.52 lb against 72.1, and it accepts 1,400W of solar against 800W. The DELTA 3 Ultra keeps the third, a 10-millisecond line-interactive switchover against 20, and it brings a far better app and a much larger community with it. That package is worth the same money if a desktop workstation is downstream or you plan to run this thing from your phone. For everybody else, the lighter box that refills faster is the buy.

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 Ultra rates 4.7/5 (80th percentile of 26 Large-class units), and HomePower 3000 rates 4.7/5 (84th percentile of 26 Large-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.
DELTA 3 Ultra: 72.1 lb Is a Two-Hands Commitment
72.1 lb is a bent-knees lift and a bad idea alone on stairs. The HomePower 3000 doesn't get you off the hook, since 59.52 lb is still a serious box, but 12.58 lb is the difference between a carry you make now and a carry you put off until someone else is home. If the unit lives in one spot forever, skip this card. If it moves, it's the most honest line on the page.
UPS Speed: 10ms Line-Interactive vs 20ms Standby
Ten milliseconds against twenty, and for a fridge, a router or a lamp the gap is nothing. Both are back before you finish noticing the lights blinked. It matters when a desktop workstation, a NAS or a gaming PC is downstream, where a longer transfer is the difference between riding through and rebooting with unsaved work. That's the DELTA 3 Ultra's cleanest win on this page, and it's a narrow one.
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.

Both units cost the same to own over their rated lives — $0.11/kWh each. Lifetime cost can't separate them, so decide on the sticker price and everything else. 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.
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 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
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
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 3000
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.

Analyst note
Neither expands, and that's no knock on either — each is a complete unit at a fixed size. They hold the same 3,072Wh, so capacity can't break the tie: decide on price, weight, and the rest, and know that whichever you pick is the ceiling.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 Ultra
Most of the published testing on this chassis was done on the step-up Plus model, which carries the same battery, the same inverter, the same surge rating and the same case, so read it as indicative rather than proofA1A2A5A9. What's there is consistent. The fans stay civil with the inverter pushed to maximum, and quieter than older EcoFlow units of the DELTA 2 Max eraA1A2. Build quality draws repeat praise, with the shell, the buttons and the AC cable all described as substantial rather than cheap, and rear port doors that slide into protective slots while they're openA9A15.
The UPS behaviour is the most-tested thing about it and it holds up: pulling the wall plug mid-session produced no dips and no shut-offs, and one reviewer with a career of APC batteries behind him said it switched over the same wayA5A6. It also doesn't cap output to whatever it's pulling at the input, which is not a given in this classA4. Two quirks worth knowing. One test found it sheds the 30A port first when you overload it, which is odd but at least predictable once you've read it hereA3. And the display washes out in direct sun badly enough that one reviewer resorted to cupping his hands around itA11. On real work, an eight-hour day with a laptop, a desktop workstation and monitors ended with 40% still in the tankA8.
“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 Jackery's ledger is short, four entries, but all of it is on this exact model rather than a sibling. The headline is size: described as the lightest and smallest 3kWh station available, a one-person carry at around 60 lb, and narrow enough at 16.4 inches to fit spaces that reject rivalsB1. The cells are LiFePO4 with strong thermal stability, rated by Jackery and reviewers at roughly 4,000 cyclesB3.
It's a home-backup unit and it tests like one: a standard refrigerator kept running for nearly two days, a 55-inch TV for around 30 hours, and a grid-to-battery handoff measured under 20 millisecondsB4. The quieter advantage is the one nobody shops for. Jackery carries the lowest reported rate of failures and warranty claims among the major brands in owner communitiesB2, which is worth real money on a unit whose support desk is the weakest part of the package.
“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.”

“Uses LiFePO4 chemistry with strong thermal stability; Jackery and reviewers rate the cells at roughly 4,000 cycles — notably higher than the figure in some spec listings, so treat lower cycle numbers with caution.”

Who Should Buy Which
Buy the DELTA 3 Ultra if you…
- →Your home office is the reason you're shopping. A desktop workstation or a NAS on the other end makes the 10ms line-interactive handoff worth more than every pound the Jackery saves.
- →You'll run it from your phone. EcoFlow's app is the better one by a wide margin, and picking it costs you nothing extra here.
- →You already own EcoFlow panels or a second EcoFlow unit and want one app, one accessory drawer and one set of cables.
- →It's going into a utility room or a basement corner and staying there, where the weight is a one-afternoon problem and the faster transfer is a permanent benefit.
Buy the HomePower 3000 if you…
- →You're pairing it with panels. This is the one that's full again by mid-afternoon instead of at sunset, and that shows up on the second morning of every long outage.
- →It's going to move: house to truck to campsite to a neighbour's garage. At around 60 lb it's a solo liftB1. The DELTA isn't.
- →You need it to fit somewhere specific, like a closet shelf, a cabinet or behind a seat. It's the narrower box of the twoB1.
- →You want the retail safety net. Jackery sits on shelves at Costco, Home Depot, Best Buy and Amazon, and a return counter beats a support ticket every time.
If neither fits
Full-time van life. That load runs 4,685Wh a day, which our scenario math puts at 179% of what either of these holds, and neither unit takes an add-on battery to close the gap, so you'd be babysitting the state of charge every afternoon. Buy a single larger unit or a properly wired house battery instead. Same answer if a CPAP is the entire job: 320Wh overnight is about 12% of either pack, so you'd wake up at 88% and $1,299 is a lot to spend on a battery you barely touch.
The Bottom Line
Buy the HomePower 3000. Two identical batteries at an identical price left three rows to decide this, and the Jackery took the two you live with: it's the lighter box, and it drinks sun fast enough to be full again before the second night of an outage. Cost to own landed on the same cent either way, which is exactly why the physical rows got to decide.
The DELTA 3 Ultra isn't the loser here so much as the specialist. If a desktop workstation or a NAS is on the other end of the cord, its faster handoff outweighs every pound the Jackery saves, and its app is the one you'd actually enjoy opening. Everyone else buys the one they can pick up alone.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Jackery HomePower 3000 lighter than the EcoFlow DELTA 3 Ultra?
Yes, and by enough to matter: 59.52 lb against 72.1 lb. That puts the Jackery at the edge of a comfortable one-person carry and the EcoFlow into find-a-friend territory. Both are still real weight, though. Neither is a unit you casually hand across a tailgate.
Can the DELTA 3 Ultra or the HomePower 3000 be expanded with extra batteries?
No. Each one is sealed at 3,072Wh with no add-on battery port, so the capacity you buy is the capacity you keep for the life of the pack. That isn't a flaw at this size, since our scenarios put an eight-hour blackout at 63% of either unit and a camping weekend at 80%. It does mean you should buy for your worst realistic day rather than your average one.
Which is better for a home blackout?
They tie on the part that matters most, because an eight-hour outage draws 1,645Wh and that's 63% of either unit. The DELTA 3 Ultra hands over faster when the grid drops, 10ms against 20ms, which counts if a desktop is plugged in. The HomePower 3000 refills faster from solar, which counts if the outage runs into a second day. Pick based on which of those your outage looks like.
How long will these run a refrigerator?
Testing on the HomePower 3000 kept a standard refrigerator going for nearly two days, alongside about 30 hours for a 55-inch TV. The DELTA 3 Ultra holds the same 3,072Wh behind the same 3,600W inverter, so expect the same ballpark. Fridge compressors surge well past their rated draw at startup, and with 7,200W of surge headroom on both, neither one is going to refuse to start one.
Is EcoFlow's app reason enough to pick the DELTA 3 Ultra?
It can be, and it costs you nothing to weigh, since both units are $1,299. EcoFlow's app is far better rated, while Jackery splits its experience across two separate apps that want a login even when you're standing next to the hardware. If you're the kind of owner who checks state of charge from bed, that's a genuine difference. If you'll read the front screen and nothing else, it's noise.
