Head-to-head test
EcoFlow DELTA 3 Ultra vs Jackery HomePower 3000
With the battery, inverter and warranty identical, this comes down to 12.58 lb and 200W of solar, both in the Jackery's favor, against a faster rated transfer that only pays off when a desktop PC is plugged into the DELTA.

Spec deltas
Swap the badges and the spec sheets barely notice: 3,072Wh each, 3,600W continuous and 7,200W surge each, at least 4,000 cycles each, five-year warranties each, and the same typical price of $1,399. Neither one expands. Cost per lifetime kilowatt-hour comes out identical to the cent, so the tiebreaker that settles most of these pages has nothing to say.
That leaves a handful of rows, and they split along a clean line. The HomePower 3000 weighs 59.52 lb to the DELTA 3 Ultra's 72.1, and it accepts 1,000W of solar to the EcoFlow's 800W. The DELTA answers with desk-side hardware: a transfer rated at ≤10ms against ≤20ms, USB-C up to 140W against 100W, and six AC outlets to five.
Take the Jackery. Its two wins are the ones you feel in an ordinary outage: every time the box moves, and every afternoon the sun has to put it back. The DELTA's wins pay off at one specific desk, the one with a desktop PC whose power supply is fussy about milliseconds. If that's your desk, the EcoFlow earns its extra 12.58 lb. If it isn't, you're carrying them for nothing.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
A home-backup unit moves more than its owner expects: out of the closet when the grid drops, over to the fridge, back again when it's over. Neither of these grows, so the box you buy is the box you haul for the life of a pack rated for about 11 years of daily cycling. Our spec record doesn't track wheels on either one, so don't count on them. Count the 12.58 lb instead, every trip, for a decade.
DELTA 3 Ultra: 72.1 lbHomePower 3000: 59.52 lbThe Jackery is billed as a one-person carry at around 60 lb, 16.4 inches wideB1Neither expands; 4,000 cycles is about 11 years of daily cycling
Why it mattersIf the unit will sit in one corner and never move, skip this; if it gets carried at all, the Jackery is the one you'll actually bother to deploy.
solar input
That's a 25% wider solar door, and it's an honest edge rather than a landslide: under an hour of strong sun from empty, under half an hour on a single night's refill. But an outage that runs past one night is the reason anyone buys 3kWh, panels rarely deliver their rated output, and clouds keep their own schedule. When the sky only gives you a short window, the box that drinks faster comes out of it fuller. It's a tiebreaker, and it breaks the same way the weight does.
DELTA 3 Ultra: 800W max solar inputHomePower 3000: 1,000W max solar inputBoth hold 3,072Wh8-Hour Blackout scenario: 1,645Wh, 63% of either unit
Why it mattersIf your backup plan involves panels rather than a wall outlet, lean Jackery; if you only ever recharge from the grid, ignore this row.
Both ceilings are ratings, not measurements, and for a fridge, a router or a lamp either one is back before you notice the lights blinked. The ≤20ms class is where the fussiest PC power supplies sit right at the line, though, and losing that bet costs a reboot and whatever wasn't saved. A unit that lives under a desk also never pays the weight tax. For the home office, the DELTA's wins land exactly where they count and its one loss stops counting.

Why it mattersIf a desktop PC, a NAS or a 140W laptop is what you're protecting, buy the DELTA 3 Ultra; for everything else its faster transfer is a trophy on a shelf.
The specific dimensions that decide these two units — everything else is a tie.
Portability & Form Factor
Selected because: The DELTA 3 Ultra weighs 72.1 lb to the HomePower 3000's 59.52, and that 12.58 lb is the difference you feel every time either unit moves.
weight
Neither of these is a grab-and-go unit. 59.52 lb is a bent-knees carry you can make alone; 72.1 lb is the one you start planning, and reviewers put the Jackery right at that one-person line at around 60 lbB1. The trip that matters isn't the campsite. It's the closet to the kitchen in the dark, the night the lights go out.
Shape is the other half. The HomePower is 16.4 inches wide and billed as the smallest 3kWh station goingB1, which decides whether it lives on a closet shelf or on the garage floor. Our record doesn't track wheels or a handle on either unit, so check the product photos before you plan on rolling the heavier one.
What the Specs Don't Tell You
Selected because: All three cards that fire are informational, and the one that favors the DELTA, its ≤10ms transfer rating, is its strongest hardware argument.
Three cards fire, and none of them is a warning. The weight card belongs to the DELTA's 72.1 lb, which is normal for 3,072Wh, just not as normal as 59.52. The UPS card is the only one that goes the DELTA's way: ≤10ms against ≤20ms, both manufacturer ceilings rather than measured results. That's the whole hardware case for the EcoFlow, and at a desk with a desktop PC it's a good one.
The warranty card is a draw with one string attached. The Jackery's term is up to five years, with registration: three years base plus two for registering the unit. Register it the day it arrives and the card is a tie. Nothing fires on surge or cycle life, because the two are identical on both.
Brand Trust
Selected because: With the hardware this close, the app you open and the support desk behind it carry more of the decision than usual.
The app gap is the widest difference on this page. EcoFlow's rates 4.6 on iOS and 4.2 on Android; Jackery's sits at 2.3 to 3.3, split across two apps, and demands a login even offline. That last part matters more than it sounds, because the night you most want to check state of charge from the couch is a blackout, and the internet tends to leave with the grid. EcoFlow's own blemish is that it tested a subscription paywall for advanced app features in early 2025 before backlash paused it. When something odd happens at midnight, EcoFlow's subreddit of about 31K members has probably seen it already; Jackery's has about 2,000.
Neither support desk is a selling point. EcoFlow's experiences are polarized, and it offers no parts or service once the warranty ends; Jackery's draws wider criticism, including strict receipt requirements on claims. The fix is the same for both: buy from Costco or Amazon and let the return window do the heavy lifting. In Jackery's favor, you may never need the phone number, since the brand carries the lowest reported rate of failures and warranty claims among the major makersB2.
Runtime: Will It Power Your Gear?
Selected because: Identical 3,072Wh packs give identical runtimes, so what separates them is the refill: 1,000W of solar input against 800W.
The runtime table is a mirror: two 3,072Wh packs behind two 3,600W inverters give the same hours at every load. The one real-world check we have runs heavier than our 910Wh Remote Workday budget. A reviewer powered a laptop, a desktop workstation and monitors for an eight-hour day on this chassis and still ended with 40% leftA8. Either unit carries a working day with room to spare.
So the number that separates them is how fast the pack comes back. Every hour of full-rated sun puts 1,000Wh into the Jackery and 800Wh into the DELTA. On a cloudless day you'd never notice. On a gray one, where the sun gives you a short window and nothing more, the extra 200Wh an hour is what you carry into the night.

Weekend Camping
Two nights off-grid with essential comfort
Either unit
A 2,100Wh weekend uses 80% of either pack and leaves the same 511Wh in reserve, so capacity can't pick. The walk from the truck can: 59.52 lb against 72.1 lb, and only one of those is a lift you'll want to repeat on Sunday.

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 unit, with the same 966Wh to spare. The split is before and after. The DELTA's ≤10ms rated transfer is the better bet if a desktop PC has to ride through the blink; the Jackery's 1,000W solar input puts the night back faster the next morning.

SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A night of CPAP is 320Wh, about 12% of either pack, so each could run roughly eight nights from its 2,611Wh usable before it needs a charge. Nothing on the spec sheet separates them at the bedside, and with the price the same, the only tiebreak left is which one you'd rather carry into the bedroom.
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.

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.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
A 4,685Wh van day is 179% of either pack, and both come up the same 2,074Wh short, about 56% covered. Neither takes an add-on battery, so the gap gets closed with daytime solar or a lighter day rather than a bolt-on. Plan around it rather than ruling either out.

Conclusion
October 11, 2026
Verdict: the HomePower 3000
Take the HomePower 3000. Both hold 3,072Wh behind a 3,600W inverter with 7,200W of surge, both are rated for at least 4,000 cycles, both carry five years of cover (the Jackery's with registration), and both sell for the same typical price, so cost per lifetime kilowatt-hour lands on the same cent. That hands the decision to the rows that differ. The Jackery weighs 59.52 lb to the DELTA's 72.1 and accepts 1,000W of solar to its 800W. The DELTA 3 Ultra answers with a ≤10ms rated transfer against ≤20ms, USB-C up to 140W against 100W, a sixth AC outlet and a far better-rated app. Those are real wins, but they're desk wins: they pay off when a desktop PC, a NAS or a big laptop is plugged in, or when you'll run the unit from your phone. Everyone else should buy the lighter box that refills faster, because it's the one they'll actually move when the power goes out.
At today's prices the DELTA 3 Ultra is the cheaper unit ($1,299 against $1,349, with the DELTA 3 Ultra $100 under its typical $1,399). At typical prices the two list the same ($1,399), and that is what the verdict weighs. Prices checked 28 days ago.

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 (85th percentile of 28 Large-class units), and HomePower 3000 rates 4.6/5 (78th percentile of 28 Large-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
DELTA 3 Ultra: 72.1 lb Is a Planned Lift
72.1 lb is a bent-knees lift and a bad idea alone on stairs. The HomePower 3000 is still a serious box at 59.52 lb, but 12.58 lb lighter is the difference between moving it now and waiting until someone else is home. Our spec record doesn't track wheels or a handle on either, so check the photos before you plan on rolling it. If it lives in one corner forever, skip this card.
UPS Rating: ≤10ms vs ≤20ms
Both are rated ceilings, not measurements, and for a fridge, a router or a lamp both are back before you notice the lights blinked. The gap matters when a desktop PC is downstream: the ≤20ms class is where the fussiest power supplies sit right at the line, and losing that bet means a reboot and whatever wasn't saved. That's the DELTA 3 Ultra's clearest hardware win on this page, and it's a narrow one.
Warranty: Five Years Each, One String Attached
Both carry five years on our record. The Jackery's is up to five years, with registration: three years base plus two for registering, so register it the day it arrives and this is a dead heat. EcoFlow's five is stated plainly, but the brand offers no parts or service once it runs out. Keep the receipt either way; Jackery in particular is strict about it on claims.

Analyst note
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 top of the range sit two whole-home paths: the TITAN line, one 5 kWh unit that grows to 30 kWh, and the DELTA Pro Ultra platform, which stacks batteries and inverters further — flagship paths, not line-wide features.
Worth knowing
EcoFlow tested a subscription paywall for advanced app features in early 2025 and paused it after backlash, and it offers no parts or service once the warranty ends.
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
Jackery's app rates 2.3 to 3.3, is split across two apps, and requires a login even offline, which is an awkward ask during the blackout this unit is bought for.
Analyst note
On hardware this close, the brands decide more than usual. EcoFlow brings the far better app and a Reddit community of about 31K; Jackery brings the wider retail footprint, with stock at Costco, Home Depot, Best Buy and Amazon. Both support desks draw criticism, so buy either from a retailer with a real return window and let that be your safety net.
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.
Adequate ports for most setups, but heavy users may want a power strip.
HomePower 3000

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
Field data on the base DELTA 3 Ultra is thin. Our own research flags that nearly all published testing was done on the Ultra Plus, a sibling with the same battery, inverter and chassis but more solar input and an expansion port, so treat what follows as indicative for this model rather than proofA0. What it says is consistent: the fans stay unobtrusive even at maximum inverter output and run quieter than older EcoFlow units like the DELTA 2 Max, though the reviewer behind that couldn't be confirmed as testing this exact modelA1A2.
Build quality draws repeat praise, with a shell, buttons and AC cable that feel substantial and rear port doors that slide into protective slots while in useA9A15. The UPS behavior is the best-tested thing about it: pulling the wall plug produced no dips or shut-offs, and one reviewer with a career of APC batteries behind him said it switched over the same wayA5A6. One reviewer ran a full eight-hour workday with a laptop, a desktop workstation and monitors and finished with 40% leftA8. The catch is the display, which washes out in direct sun badly enough that one reviewer cupped his hands around it to read itA11.
“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 but mostly on this exact model. It's billed 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 turn rivals awayB1; part of that description comes from Jackery's own site, so read the superlative as marketing and the weight as the fact it matches. In home-backup testing it kept a standard refrigerator running for nearly two days and a 55-inch TV for around 30 hours, with a grid-to-battery handoff measured under 20 millisecondsB4.
The quieter advantage is brand-level rather than model-level: Jackery carries the lowest reported rate of failures and warranty claims among the major brands in owner communitiesB2. One source rates the LiFePO4 cells around 4,000 cycles with strong thermal stability, though our researcher couldn't confirm it describes this exact modelB3; the 4,000-cycle rating on our record stands on its own.
“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 Ultra if you…
- →A desktop PC or a NAS is the reason you're shopping. The ≤10ms rated transfer sits clear of the line where fussy PC power supplies drop out, on paper at least, and a unit that lives under a desk never pays its weight penalty.
- →Your laptop charges at up to 140W over USB-C. The DELTA feeds it at full rate straight from the port; the Jackery tops out at 100W.
- →You'll manage it from your phone. EcoFlow's app rates 4.6 on iOS against Jackery's 2.3 to 3.3, and Jackery's wants a login even offline.
- →You already run EcoFlow panels or a second EcoFlow unit and want one app and one drawer of cables.
Buy the HomePower 3000 if you…
- →It's going to move: closet to kitchen in an outage, garage to truck bed on a camping weekend. At 59.52 lb it's a solo carry; the DELTA's 72.1 lb usually isn't.
- →You're pairing it with panels. 1,000W of solar input against 800W means it comes out of every short sunny window fuller.
- →It has to fit somewhere specific, like a closet shelf or a cabinet. At 16.4 inches wide it's the narrower boxB1.
- →You want a return counter rather than a support ticket. Jackery is stocked at Costco, Home Depot, Best Buy and Amazon.
If neither fits
Full-time van life: a 4,685Wh day leaves either unit 2,074Wh short, and neither takes an add-on battery, so you'd be planning every afternoon around the gap; an expandable unit or a dedicated house battery suits that life better. Same answer if you need a 240V well pump or a 30A RV hookup, since both record zero outlets of either kind; that's split-phase home-backup territory. And if a CPAP is the whole job, 320Wh a night is about 12% of either pack, so a much smaller unit does it for far less money.
The Bottom Line
Buy the HomePower 3000. Same battery, same inverter, same price, same cost per lifetime kilowatt-hour, and the Jackery takes the two rows you live with: it's the 12.58 lb lighter box, and it drinks sun faster when an outage runs past one night.
The DELTA 3 Ultra is the specialist, not the loser. Put a desktop PC, a NAS or a 140W laptop on the other end of the cord and its faster rated transfer and stronger USB-C earn every extra pound. Everyone else should buy the one they can carry 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, by 12.58 lb: 59.52 lb against 72.1 lb. That puts the Jackery at the edge of a one-person carry and the EcoFlow into find-a-helper territory. Neither is light, and our record doesn't track wheels on either, so check the photos before you plan on rolling one.
Which is better for keeping a desktop computer on during a power outage?
The DELTA 3 Ultra. Its transfer is rated at ≤10ms against the HomePower 3000's ≤20ms, and the slower class is where the fussiest PC power supplies sit right at the line. Both figures are manufacturer ceilings, not lab results, and for a fridge or a router either one is plenty fast.
Which charges faster on solar, the DELTA 3 Ultra or the HomePower 3000?
The HomePower 3000, which accepts 1,000W of solar against the DELTA's 800W. At full rated input that's about three hours from empty versus about four for the same 3,072Wh. Real panels rarely hit their rating, so treat both as best cases, but the proportion holds.
Can the DELTA 3 Ultra or the HomePower 3000 add extra batteries?
No. Both are sealed at 3,072Wh, so that's the ceiling for the life of the unit. It covers our eight-hour blackout at 63% of either pack and a camping weekend at 80%, but buy for your worst realistic day rather than your average one.
How long will the DELTA 3 Ultra or HomePower 3000 run a refrigerator?
In testing, the HomePower 3000 kept a standard refrigerator running for nearly two days. The DELTA 3 Ultra carries the same 3,072Wh behind the same 3,600W inverter, so expect the same ballpark. Both list 7,200W of surge, double their continuous rating, so a household compressor's startup kick sits well inside either one.
