Head-to-head test
EcoFlow DELTA 3 Ultra Plus vs Jackery HomePower 3600 Plus
With weight (77.2 lb), noise (30 dBA), and output (3,600W) all dead even, this comes down to the Jackery's 512Wh-bigger battery and 2,000 extra cycles against the EcoFlow's $120-lower price and faster UPS handoff, and if you plan to actually cycle it, more battery that lasts longer wins.

Spec deltas
Take the Jackery HomePower 3600 Plus, though this is the closest an EcoFlow has come to changing our answer. The two share a 77.2-lb body, a 30 dBA noise rating, a 3,600W inverter, and a 7,200W surge, the specs that usually crown a winner. Here they cancel, and the decision falls to the battery.
That is the Jackery's ground. It holds 512Wh more (3,584 to 3,072), carries 2,000 more rated cycles (6,000 to 4,000), and swallows 400W more solar. Push those ratings to their end and it banks 21,504 kilowatt-hours over its life to the EcoFlow's 12,288, which is why it costs eight cents per lifetime kilowatt-hour against twelve, cheaper to own even though it rings up higher.
The EcoFlow's answer is honest and specific: $120 less today ($1,499 to $1,619), a 10ms UPS switchover to the Jackery's 20ms that a bare desktop will prefer, and genuinely useful app touches like Storm Guard, which tops the unit up when a storm is forecastA12. Buy it for occasional backup with better software and you have bought well. Cycle it hard, daily solar and regular outages, and you have paid $120 to own the smaller, shorter-lived battery, and the next decade quietly bills you the difference back.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
Multiply capacity by cycles and the Jackery has 21,504 kilowatt-hours in it to the EcoFlow's 12,288, an extra 9,216 from a pack that shares the same case size and warranty. That inverts the price tags: eight cents per lifetime kilowatt-hour for the Jackery, twelve for the EcoFlow. Cheaper to buy, costlier per unit of everything it will ever do.
Capacities: 3,072Wh (DELTA 3 Ultra Plus) vs 3,584Wh (HomePower 3600 Plus)Cycle ratings: 4,000 vs 6,000Prices: $1,499 vs $1,619Lifetime energy: 12,288 kWh vs 21,504 kWh
Why it mattersAnyone who cycles it rather than shelving it for the rare outage should pay the $120 once and stop overpaying per kilowatt-hour forever.
The EcoFlow's 10ms is line-interactive class; the Jackery's 20ms is standby class, and while most electronics ride through both, a desktop PC without its own battery has a wider safety margin at 10ms. Reviewers found the EcoFlow held its output cleanly when yanked off wall powerA6. This is the one spec where the cheaper unit is also the better one.
Switchover: 10ms (DELTA 3 Ultra Plus) vs 20ms (HomePower 3600 Plus)Both hold about 3kWh and are built to sit inline as home backupOne reviewer saw no output dip when the EcoFlow was unplugged from the wallA6
Why it mattersIf a bare desktop or a sensitive workstation is what you're protecting, the EcoFlow's faster handoff is a real, if narrow, reason to pay less and still win.
solar input
For a fridge-and-router blackout both coast (54% and 63% used), so the capacity gap is invisible until the day is heavy; then the Jackery's extra 512Wh and 400W-taller solar ceiling let it both go longer and refill faster. Neither survives a full 4,685Wh van-life day bare, so that buyer needs expansion no matter the badge.
Weekend Camping (2,100Wh) draws 80% of the EcoFlow's usable capacity vs 69% of the Jackery'sSolar input: 1,600W vs 2,000WVan Life Daily (4,685Wh) overruns both units
Why it mattersLight, occasional loads won't feel the difference; heavy or multi-day use is exactly where the Jackery's bigger, faster-refilling battery earns its $120.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: cheaperToOwn is p2, and the capacity plus cycle gap is the whole verdict; this is the decision axis.
cost / lifetime kWh
The engine splits its verdict cleanly: the EcoFlow is cheaper to buy, the Jackery is cheaper to own, and the second number is the one that compounds. At daily cycling the EcoFlow's 4,000-cycle rating runs out around year 11; the Jackery's 6,000 runs to 16.4. That's about five more years of the same battery from the same-size case, and it's the reason the lifetime-cost gap never closes back up.
One row here genuinely favors the EcoFlow: cost per warranty-year, $300 against $324, because both warranties run five years and the EcoFlow's sticker is lower. If you only trust a battery as far as its paperwork, the cheaper unit is the rational pick. If you trust the cycle ratings, and both are LFP packs from serious makers, the math tilts to the Jackery and stays there.
Your Life, Your Pick
Selected because: Weekend Camping goes to p2 on headroom, the rest are 'both'; shows the capacity margin only bites on heavy loads, and van life fails both.
Five of six modeled days come back livable on both boxes: an 8-hour blackout takes 63% of the EcoFlow and 54% of the Jackery, a CPAP night about a tenth of either, a remote workday roughly a third. The gap between the columns is always the same 512Wh of headroom, and on light loads you never reach for it.
It reaches for you on the big days. A 2,100Wh camping weekend leaves the EcoFlow at 80% used and the Jackery at 69, the one scenario the engine hands to a single unit. And a 4,685Wh van-life day overruns both by half again, so that life starts with an expansion battery, not with this decision. Choose on the days you actually run heavy, because the light ones are a coin flip.
What the Specs Don't Tell You
Selected because: Three cards fire: weight ties, cycleLife favors p2, and ups is p1's one genuine win; the honest catch lives here.
rated cycles
Three cards fire, and for once they don't all point one way. Weight is a genuine tie, both are 77.2 lb, a two-hands lift nobody enjoys, so that card is about the class, not the contest. Cycle life is the Jackery's: 6,000 rated cycles to 4,000, the same gap driving the whole lifetime-value case.
The third card is the EcoFlow's, and it's the honest one to volunteer: its 10ms switchover is line-interactive class, a step quicker than the Jackery's 20ms standby handoff. For a fridge or a router the difference is academic; for a bare desktop PC it's the safer bet. Two cards to the Jackery's ledger, one to the EcoFlow's, and none of them about noise, which ties at 30 dBA.
Brand Trust
Selected because: Cross-brand pair where p1's strongest real case (app/community/ecosystem) and p2's weakness (app/support) both live.
This is the EcoFlow's best section, and it's not close. Its app rates 4.6 on iOS to Jackery's 2.3, it anchors the biggest community in portable power (a roughly 31K-member subreddit to Jackery's 2,000), and it brings genuinely useful software like Storm Guard, which charges the unit ahead of forecast weatherA12. Jackery's app is the category's weakest and demands a login even offline, in the exact blackout you bought it for.
Support is where both brands earn the same advice: buy from Costco or Amazon and keep the receipt. EcoFlow's record is polarized, painless prepaid replacements for some and long waits with refurbished units for others, and it carries an October 2025 recall of the DELTA Max 2000, a different model, plus a since-shelved experiment charging for app features. Jackery's support reputation is simply worse: slow, scripted, receipt-strict. The EcoFlow makes the stronger platform; the Jackery makes the stronger battery. This page is about the battery.

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 leaves the EcoFlow at 80% drained and the Jackery at 69%, so the Jackery walks away from the site with more in reserve, the one scenario where the 512Wh capacity gap actually decides it. Both finish the trip on a single charge; only one still has a comfortable buffer for a longer second day.
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
Eight hours of essentials pulls 63% from the EcoFlow and 54% from the Jackery, so both coast through the night with room to spare. They separate only if the outage runs long: the Jackery takes 2,000W of solar to the EcoFlow's 1,600W, so on day two the same panels bring it back to full sooner.
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 sips roughly a tenth of either battery overnight, and at that trickle both stay quiet at their shared 30 dBA rating. This one is a genuine tie; if it lives on your nightstand, decide on price and the app you'd rather stare at, not on runtime.
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
A laptop-and-monitors day takes about a third of either unit through identical 100W USB-C ports, so there's no daylight between them here. Pick on the desk you're protecting: the EcoFlow's 10ms switchover is the slightly safer catch for a desktop without its own battery.
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, consider weight: the lighter unit is easier to load into a truck bed. Also check if either has Bluetooth speaker-level noise. Fan sound matters in social settings.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
The one scenario with a hard verdict, and it's a double rejection: a 4,685Wh day overruns both packs by roughly half again. Neither does van life bare. Plan on an expansion battery from day one and make that the real purchase decision, not the choice between these two base units.

Conclusion
July 13, 2026
Verdict: the Jackery HomePower 3600 Plus
Both units land on the same 77.2-lb frame, the same 30 dBA rating, and the same 3,600W output with a 7,200W surge, so the physical stuff that usually breaks a tie doesn't. The Jackery HomePower 3600 Plus wins the battery: 3,584Wh to 3,072, 6,000 rated cycles to 4,000, and 2,000W of solar intake to 1,600, which is why it banks 21,504 lifetime kilowatt-hours to the EcoFlow's 12,288 and costs eight cents per lifetime kilowatt-hour against twelve. The EcoFlow DELTA 3 Ultra Plus has a real rebuttal: it's $120 cheaper up front, it switches to battery in 10ms to the Jackery's 20ms (the safer handoff for a bare desktop), and it brings app features like Storm GuardA12 plus the biggest community in the category, where Jackery's software rates near the bottom. Long-term field data on this specific EcoFlow is still thin given how new it is, so unless the lower price, the faster UPS, or the ecosystem tips it, take the Jackery.

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 Plus rates 4.9/5 (96th percentile of 25 Large-class units), and HomePower 3600 Plus rates 4.3/5 (60th percentile of 16 Home Backup-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
A Rare Weight Tie
Both units land at exactly 77.2 lb, so the scale doesn't break this one. That's a two-hands, bent-knees lift on either, nobody is one-arming a 77-lb box up basement stairs, which makes weight the spec you re-negotiate every time it changes rooms, and it costs the same on both sides. If mobility matters, judge the handles and roll setup on each in person, not the number.
The EcoFlow's One Spec Win
Switchover is the single spec that favors the DELTA 3 Ultra Plus: 10ms puts it in line-interactive territory, a step quicker than the HomePower's 20ms standby-class handoff. For a fridge, a router, or a modem the gap is academic, both are far inside the safe window. For a desktop PC running without its own battery, the faster catch is the safer bet, and it's the clearest reason on the page to take the cheaper unit.
The Card Carrying the Verdict
Rated cycle life is where these two split hardest: 6,000 charges for the HomePower against 4,000 for the DELTA 3 Ultra Plus, from batteries only 512Wh apart in size. Cycle one daily and that gap is about five extra years of service, roughly 16 years against 11, which is exactly why the Jackery ends up cheaper to own even though it costs more to buy.

Brand trust
EcoFlow
Ecosystem
The deepest catalog in portable power, a dozen-plus models across the DELTA and RIVER lines, solar panels, and smart home panels, plus X-Stream fast charging and modular expansion that scales far past this unit.
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
The strongest software and community in the category: a 4.6-rated iOS app with features like Storm Guard, which charges the unit ahead of forecast storms, and the largest owner base in portable power for troubleshooting.
Worth knowing
EcoFlow offers no parts or service once the five-year warranty ends, briefly tested subscription paywalls for app features before backlash shelved the plan, and issued an October 2025 recall on the DELTA Max 2000, a different model but worth knowing. The app leads the category; the company's moves are worth watching.
Jackery
Ecosystem
Recognized everywhere and stocked everywhere, Costco, Home Depot, Best Buy, Amazon, across the Explorer and HomePower lines, with the SolarSaga panel range alongside.
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
Wide availability and a proven, dependable reputation, now paired in this unit with a 6,000-cycle EV-grade LFP pack, the longevity Jackery was historically slow to adopt, finally here.
Worth knowing
The app is the category's weakest and wants a login even offline, and support draws consistent criticism for slow, scripted responses and strict receipt rules. Buy this one for the hardware and the price, and lean on the retailer's return policy rather than the brand's.
Analyst note
EcoFlow sells the platform: the deepest catalog, the best app, the biggest community, and a genuine UPS-speed edge, priced a touch lower here and moving fast enough to generate the occasional recall or paywall experiment. Jackery sells the battery: more capacity, far more cycles, and a lower cost to own, wrapped in weaker software and criticized support. Either way, buy from a retailer with painless returns. Then decide whether you're paying for the software around the battery or the battery itself.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 Ultra Plus
The catch on the EcoFlow's field record is its age: this unit is new enough that independent long-term owner reports are thin, and most of what exists is short-run review-site testing rather than six-month ownership. Within that window the notes are consistent. Reviewers describe it staying quiet even under sustained loadA13, praise a shell, buttons, and cable that feel substantial rather than fragileA8, and note it shrugged off being unplugged from the wall with no output dipA6. One reviewer ran a full eight-hour workday on it, laptop, desktop workstation, and monitors, and still had charge to spareA5.
Two honest quirks turned up. Overload it and the 30A port is the first to cut outA3, and the display washes out in direct sun, forcing the old cup-your-hands trick to read itA7. Neither is a dealbreaker, but both are the kind of thing you only learn from someone who used it, and there aren't many of those voices yet.

Research compiled July 13, 2026.
Who Should Buy Which
Buy the DELTA 3 Ultra Plus if you…
- →You want this class at its lowest price and mostly for insurance, a few outages a year rather than daily cycling. The runtime is a near-match and the $120 saving is the EcoFlow's cleanest win.
- →A bare desktop or sensitive workstation is what you're protecting. The 10ms switchover is line-interactive class, a genuine step up from the Jackery's 20ms for gear without its own battery.
- →You want the better software and the bigger community: a 4.6-rated app with touches like Storm GuardA12, and the largest owner community in the category when something needs troubleshooting.
Buy the HomePower 3600 Plus if you…
- →You'll actually cycle it: daily solar, regular outages, real use. The 6,000-cycle rating buys about five more years of daily duty than the EcoFlow before the math retires it, and it costs less per kilowatt-hour the whole time.
- →Your heavy days are real. The extra 512Wh is the margin that turns a tight camping weekend into a comfortable one and stretches a long outage further on one chargeB3.
- →You want the most battery and the fastest solar refill for the money. 3,584Wh and 2,000W of solar intake are both the larger numbers here, and the lower lifetime cost per kilowatt-hour is the payoff.
If neither fits
If your day looks like van life, a 4,685Wh daily draw that overruns both by half again, buy neither bare; start from an expansion battery or a bigger platform. And if you're only covering a desk, a router, and a phone through storm season, both are overkill; a 1kWh-class station does that job for a fraction of the price and half the weight.
The Bottom Line
Take the HomePower 3600 Plus. The two are the same 77.2-lb, 30 dBA, 3,600W machine on the outside, so you're not choosing performance, you're choosing the battery inside, and the Jackery's is 512Wh bigger, rated for 2,000 more cycles, and cheaper to own per kilowatt-hour for the decade you'll run it.
Take the EcoFlow if the $120 matters today, if a bare desktop needs its 10ms UPS, or if you want the better app and the bigger community behind it, three honest, specific reasons, and given how new the EcoFlow is, its long-term field record can't yet add a fourth. Everyone else who plans to actually use this thing: buy the Jackery, wire it in, and forget it's there.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Jackery HomePower 3600 Plus worth $120 more than the EcoFlow DELTA 3 Ultra Plus?
For anyone who cycles it, yes. The two match on weight (77.2 lb), noise (30 dBA), and output (3,600W with a 7,200W surge), but the Jackery holds 512Wh more and is rated for 2,000 more charge cycles, which is why it costs less to own per kilowatt-hour despite the higher sticker. Skip the premium only if you want the EcoFlow's lower price, faster UPS, or better app instead.
Which lasts longer, the DELTA 3 Ultra Plus or the HomePower 3600 Plus?
The Jackery, by a wide margin on paper. It's rated for 6,000 charge cycles to the EcoFlow's 4,000, which at daily use works out to about 16.4 years against 11, roughly five more years from a same-size battery. Both use LFP chemistry, so both should hold up well; the Jackery simply has more cycles banked in the rating.
Can either one run a refrigerator through a blackout?
Yes, comfortably. Our modeled 8-hour blackout, a fridge plus essentials, takes 63% of the EcoFlow and 54% of the Jackery, and both surge to 7,200W, well past any household fridge's startup spike. In a three-day outage, one Jackery owner ran a fridge, microwave, fans, and a CPAP for two straight days on a single charge. For longer outages, both add solar and expansion batteries.
Which is the better UPS for a home office?
The EcoFlow, narrowly. It switches to battery in 10ms (line-interactive class) to the Jackery's 20ms (standby class); most routers, modems, and laptops ride through either, but a desktop PC without its own battery has more margin at 10ms. Wire either between the wall and your essentials and a grid blip becomes a non-event, and the EcoFlow just clears the bar with a little more room.
Which charges faster from solar?
The Jackery accepts up to 2,000W of solar to the EcoFlow's 1,600W. From empty in strong sun both land around two hours, since the Jackery also has more to refill, but the higher ceiling means a big multi-panel array banks more of each day's sun, which matters most in a multi-day outage. For a panel or two, they're effectively even.
