Head-to-head test
EcoFlow DELTA 3 Ultra vs Jackery HomePower 3600 Plus
These are the same 77-pound, 3,600-watt box under different badges, so the only real question is whether the Jackery's bigger, longer-lived battery is worth $420 more than the EcoFlow's cheaper, faster-switching one, and only a battery you cycle hard ever pays that back.

Spec deltas
Line these two up and the spec sheets nearly merge: 3,600 watts of output, a 7,200-watt surge, 77.2 pounds on the scale, the same 30 dBA hum, the same 100W USB-C, five-year warranties on both. The rows that actually differ come down to four: price, capacity, cycle life, and switchover speed.
The EcoFlow DELTA 3 Ultra is $1,199, which is $420 under the $1,619 Jackery HomePower 3600 Plus, and at $0.39 per watt-hour it's the stronger value walking in the door. The Jackery answers with a bigger battery (3,584Wh to 3,072Wh) and a longer-lived one (6,000 charge cycles to 4,000), which makes it cheaper to own per lifetime kilowatt-hour: eight cents against ten. On paper it's the more complete machine.
Here's the call: for the home-backup-and-occasional-trips life most of these units actually lead, take the EcoFlow and pocket the $420. You'll never cycle a 3kWh box often enough to spend down the Jackery's longevity edge, both units coast through every realistic blackout and camp with margin, and the EcoFlow's faster 10ms switchover is the one performance row that separates them. The Jackery earns its premium in exactly two hands: daily cyclers, and people who need the extra 512Wh of runtime every charge.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
But a per-kWh discount is only real if you deliver those kilowatt-hours, and reaching 6,000 cycles takes a lifetime of hard use. At the weekly cycling a backup unit typically sees, even the EcoFlow's 4,000-cycle rating runs past 75 years; both batteries age out of relevance long before they wear out. The Jackery's lifetime-value win is genuine only for someone cycling daily, where the gap narrows to a concrete 16 years against 11.
EcoFlow DELTA 3 Ultra: $1,199, 3,072Wh, rated 4,000 cycles, about 12,288 kWh over its lifeJackery HomePower 3600 Plus: $1,619, 3,584Wh, rated 6,000 cycles, about 21,504 kWh over its lifelifetime cost works out to $0.10 per kWh for the EcoFlow, $0.08 for the Jackery
Why it mattersDaily cyclers and off-grid full-timers should bank the Jackery's cheaper lifetime energy; anyone cycling weekly or less should treat both as effectively immortal and let the $420 upfront gap decide.
Capacity
That premium only converts to an advantage when you actually use the headroom, and most loads on this page don't come close: a CPAP night takes 12% of the EcoFlow, an 8-hour blackout 63%, a workday about a third. The one scenario that leans on the extra capacity is the long off-grid weekend, where the Jackery finishes with a visibly wider reserve.
the Jackery holds 3,584Wh to the EcoFlow's 3,072Wh, which is 512Wh or about 17% morethat capacity gap comes bundled with the $420 price gapa two-night camping load of 2,100Wh leaves the Jackery at 69% and the EcoFlow at 80%
Why it mattersIf your loads fit inside 3,072Wh with room to spare, and for backup and short trips they do, you'd be buying 512Wh you rarely drain; if you routinely run a 3kWh tank to the bottom, that headroom is what you're paying for.
A desktop mid-render, a NAS mid-write, or certain medical devices can trip on a 20ms gap that a fridge shrugs off, and here the cheaper unit is the one with the faster handoff, with reviewers of the Ultra-tier hardware reporting clean cutovers and no observed dipsA5A6. It's the single performance row where the EcoFlow beats the bigger, pricier Jackery outright.

Why it mattersBacking up sensitive electronics that care about transfer time tips the call to the EcoFlow; backing up a fridge and some lamps, ignore this row entirely.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The core of the verdict: Jackery is cheaper to own per lifetime kWh, EcoFlow cheaper to buy, and the tradeoff turns on cycling frequency.
cost / lifetime kWh
This table is where the Jackery looks best and where the asterisk hides. Nearly the same tank, half again the cycles, so per kilowatt-hour it ever delivers the Jackery is the cheaper unit, eight cents to ten. Every dollar of its $420 premium is buying future energy at a discount, on one condition: that the energy actually gets delivered.
A backup unit cycled a few dozen times a year never collects most of that. The EcoFlow's 4,000 cycles is already more than a decade of daily use and the better part of a century at weekly use, so for the way these boxes usually live, both outlast the buyer and the discount never lands. Read the same table as a heavy cycler, an off-grid cabin or van weekends most months, and it flips: that buyer is exactly who the Jackery's cheaper lifetime energy was priced for.
Your Life, Your Pick
Selected because: Every scenario ties or both-handle except Weekend Camping (p2 on margin) and Van Life (neither); the near-tie is itself the finding.
Run the load list and the two columns mostly agree: a CPAP night, a workday, a tailgate, an 8-hour blackout all land comfortably inside both batteries, with the EcoFlow simply sitting a few points higher on the meter because it's the smaller tank. Every one of those is a win for both units, not a separator.
Only the two-night camping trip actually asks the question, and there the Jackery's extra 512Wh answers it: 69% drawn against the EcoFlow's 80%, both home but the Jackery holding the wider cushion for a cloudy morning. The van-life day is the other bookend, where 4,685Wh overruns both, so that buyer is shopping the wrong size class, not choosing between these two.
What the Specs Don't Tell You
Selected because: Four info cards fire; weight is a wash, warranty and cost-per-year favor EcoFlow, UPS favors EcoFlow, cycleLife favors Jackery but only for heavy use.
rated cycles
Four flags fire and none of them is a landmine. Weight is a dead tie at 77.2 pounds each, the same two-handed lift on the same wheels, so it can't break anything. Warranty ties on length at five years, but per covered year the cheaper unit is cheaper there too: $240 against $324.
The two that carry information point opposite ways. Cycle life favors the Jackery, but only in the heavy-use math from a moment ago. Switchover favors the EcoFlow, and unlike cycle life it pays immediately: 10ms against 20ms is the line between line-interactive and standby behavior, and it's the EcoFlow's one clean everyday win over the bigger unit.
Brand Trust
Selected because: Cross-brand pair with a real app and ecosystem gap (EcoFlow) versus retail availability (Jackery); support is a wash worth naming.
Cross-shop the companies and the gap is software and depth. EcoFlow's app rates 4.6 on iOS and 4.2 on Android to Jackery's 2.3-to-3.3, and its lineup and owner community are the largest in portable power; if you like to monitor and tune from your phone, this is not close. Jackery counters with the thing EcoFlow can't match: shelf presence at Costco, Home Depot, and Best Buy, and the return counter that comes with it.
Support is a coin flip either way, both brands running hot and cold between hassle-free replacements and long email runarounds, so the advice is the same for both: buy from a retailer with a generous return window and register the warranty the day it lands. Neither company's service record should decide this; the EcoFlow's better app and the Jackery's easier returns are the parts worth weighing.
Growth Path
Selected because: Both expand from their own line, so this neutralizes an expandability assumption in one paragraph.
solar input
Both take expansion batteries from their own line, so neither is a sealed box and neither earns an edge here; file expandability under tie and move on. The only real caveat is the usual one: if you already know you need well past 3kWh, bolting add-ons onto either base unit costs more per watt-hour than buying a bigger station up front. Grow into these if your needs creep, but don't buy one planning to double it on day one.

SCN-01 · 2 nights · needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
HomePower 3600 Plus
A two-night, 2,100Wh camp draws the Jackery down to about 69% and the EcoFlow to 80%. Both finish the weekend, but the bigger tank keeps more in reserve for a cloudy morning or one more phone. This is the clearest case for the Jackery's extra 512Wh: not that the EcoFlow can't do it, but that the Jackery does it with a wider margin.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Either unit
A fridge-lights-and-router night runs about 1,645Wh, 63% of the EcoFlow and 54% of the Jackery, so both clear it with room left and both switch to battery fast enough that nothing on the circuit blinks. The EcoFlow hands off in 10ms to the Jackery's 20ms; for a fridge that gap is invisible, for a desktop mid-save it isn't.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP sips about 320Wh overnight, 12% of the EcoFlow and 11% of the Jackery, so capacity is beside the point here. What matters two feet from your pillow is fan noise, and both list the same 30 dBA, near-silent floor. Call this one a tie and let it settle on price.

Either unit
A laptop-desktop-monitors day pulls roughly 910Wh, about a third of either battery (35% of the EcoFlow, 30% of the Jackery). Neither breaks a sweat, both deliver it over identical 100W USB-C, and you could run two such days before recharging. No separation here, so decide on other rows.

Tailgate Party
Game day power for the crew
Either unit
A 670Wh tailgate of speakers, a blender, and a warming tray uses barely a quarter of either unit (26% of the EcoFlow, 22% of the Jackery). Both coast, and both start a compressor cooler on the same 7,200W surge ceiling. Runtime is a non-issue; pick on price and which app you'd rather live with.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
A full van-life day asks for about 4,685Wh, roughly 179% of the EcoFlow and 154% of the Jackery, so neither box carries it alone. Both take same-brand expansion batteries, so either can grow into the job, but if this is your everyday draw, budget for that second battery from day one or start a size class up.

Conclusion
July 13, 2026
Verdict: the DELTA 3 Ultra
Take the EcoFlow DELTA 3 Ultra unless you'll genuinely cycle this thing hard. The Jackery HomePower 3600 Plus is cheaper to own per lifetime kilowatt-hour (eight cents to ten) and it's the bigger, longer-lived battery, 3,584Wh and 6,000 cycles against 3,072Wh and 4,000. But that lifetime discount only pays out if you drain the pack often enough to reach those cycles, and at the home-backup duty these 3kWh units mostly see, even the EcoFlow's rating outlives you, running past 75 years at a weekly cycle. Meanwhile the EcoFlow is $420 cheaper today, switches over faster (10ms to 20ms) for anything sensitive on the circuit, carries the better app and deeper ecosystem, and covers every realistic blackout and camping load with margin. The honest flip: if you cycle daily, run an off-grid cabin, or routinely bottom out a 3kWh tank, the Jackery's extra 512Wh and longer life are worth the premium, and it's the pick our lifetime-value math would make on cycling alone.

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 5.0/5 (99th 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.
The Weight Is a Wash
Both units land at 77.2 pounds, close enough to identical that weight can't break this tie. It's a two-hands, bend-your-knees lift either way, and both ship with wheels and a handle for the pavement stretch. Carry it up stairs or over a tailgate and you're doing the same work regardless of the badge.
10ms vs 20ms, the EcoFlow's One Clear Edge
The EcoFlow switches to battery in 10ms, line-interactive territory; the Jackery takes 20ms, standby class. Both keep a fridge, router, or TV alive through a grid blink without a flicker. The difference only surfaces for gear that's genuinely picky about transfer time, a desktop mid-render, some NAS units, certain medical devices, where the EcoFlow's faster handoff is the safer bet.
6,000 Cycles vs 4,000, Real Years Only If You Spend Them
The Jackery's pack is rated for 6,000 cycles to the EcoFlow's 4,000, half again the lifespan on paper. At a full cycle every day that's about 16 years against 11, a real gap. Drop to a weekly cycle, though, and the EcoFlow's rating already stretches past 75 years; nobody out-cycles that. This number only pays the people who drain the battery hard and often.

Brand trust
EcoFlow
Ecosystem
The deepest lineup in portable power, a dozen-plus models across the DELTA Pro, DELTA 3, and RIVER lines, with solar panels and whole-home smart panels on the same platform.
Support
US-based phone, email, and chat, with genuinely mixed outcomes: many hassle-free prepaid-label replacements alongside long waits and the occasional refurbished unit on a new-unit claim. Buying through Costco or Amazon adds a 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 hardware in the category and the most active release cadence, plus the largest owner community and the best-rated app of the two by a wide margin.
Worth knowing
An October 2025 recall of the older DELTA Max 2000 for overheating risk is worth noting, and EcoFlow floated app-feature paywalls in early 2025 before backlash paused them. No out-of-warranty parts or service.
Jackery
Ecosystem
A dozen-plus models across the Explorer and HomePower lines plus SolarSaga panels, sold through the widest retail footprint in the category: Costco, Home Depot, Best Buy, Amazon.
Support
US-based, and the weaker record of the two, with slow, scripted responses and strict receipt requirements common on warranty claims. The Costco or Amazon return window is the more reliable backstop.
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
Brand recognition and shelf presence nobody else matches, the dependable and widely available default, with EV-grade LFP cells rated for a long service life on this model.
Worth knowing
Jackery was slow to move some lines to LFP and is often seen as paying for the name, and the app is the weakest of the majors, split across two confusing apps that demand a login even offline.
Analyst note
Same idea, opposite strengths. EcoFlow brings the better app, the deeper accessory bench, and faster charging; Jackery brings unmatched retail availability and the easy Costco return. Support is a wash, both running hot and cold, so on brand alone the tiebreakers are software for the EcoFlow and the return counter for the Jackery.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 Ultra
Straight talk: real long-term owner data on the base DELTA 3 Ultra barely exists yet. Most of what's out there is launch-window professional review coverage, and several of those outlets tested the near-identical Ultra Plus variant rather than this exact unit, with EcoFlow's overlapping naming and matching 3,072Wh output blurring which is which. Treat what follows as first impressions, not a proven track record.
With that caveat attached, the review coverage of the Ultra-tier hardware is consistent: the units run quiet even at high outputA1A2, hand off cleanly with no dips or shutoffs when you pull the plugA5A6, and feel premium and substantial from the casing to the sliding port-cover doorsA9A15. The roughly 74-to-77-pound heft draws the expected portability grumble, softened by wheels and a telescoping handleA10A14, and one reviewer had to cup a hand over the display to read it in direct sunA11.

Jackery HomePower 3600 Plus
The Jackery's field record is thinner in volume but clearer in aim. Reviewers peg it as a light-for-its-class 3.6kWh home-backup unit, about 77 pounds with wheels and a pull handleB2, running an EV-grade LiFePO4 pack rated for 6,000 cycles that translates to well over a decade of serviceB1. It holds a 4.5-out-of-5 Amazon rating, with buyers calling out easy setup, quiet operation, and reliable performanceB4.
The most useful single account: in a three-day regional blackout, one owner ran a fridge, a microwave, string lights, fans, and a CPAP for two straight days on one chargeB3, a real-world echo of the runtime math on this page. Like the EcoFlow, though, this is early coverage rather than years of accumulated history, and the 6,000-cycle promise in particular is a rating, not yet a track record.

- →You're backing up something that cares about a clean cutover, a desktop mid-render, a NAS, a home lab. The 10ms switchover is line-interactive where the Jackery's 20ms is standby, and it's the EcoFlow's clearest edge.
- →You want the better app and the deeper bench. EcoFlow's software rates 4.6 on iOS to Jackery's 2.3-to-3.3, and its accessory and expansion lineup is the widest in the category.
- →Value is the point: at $0.39 per watt-hour the EcoFlow is the stronger buy walking in the door, and the $420 you save covers a solar panel or a good chunk of one.
Buy the HomePower 3600 Plus if you…
- →You'll cycle it hard, an off-grid cabin, van weekends most months, daily draws. That's the only place the 6,000-cycle pack turns from spec-sheet trivia into real money, closing to a genuine 16 years of daily service against the EcoFlow's 11.
- →You routinely bottom out a 3kWh tank and want the cushion. The extra 512Wh is 17% more runtime every charge, and it's what wins the long, no-recharge weekend outright.
- →You lean on solar in long outages. The Jackery takes 2,000W of panels to the EcoFlow's 1,600W and pairs it with the bigger bank, so it refills its larger battery in about the same window and stores more when the sun is out.
- →Your buying safety net is the Costco or Best Buy return counter, and brand familiarity matters more to you than app polish.
If neither fits
If your daily reality is van-life scale, pushing 4,685Wh a day, a single 3kWh box is the wrong tool no matter the badge; start with a larger expandable system or plan a second battery from the outset. And if the real job is phones, a laptop, and a lamp, both of these are far more station than you need, and a 1kWh unit does it for hundreds less.
The Bottom Line
Strip the badges and you're choosing between the same 3,600-watt, 77-pound box twice, so the money question is simple: the Jackery is the bigger, longer-lived battery and cheaper per lifetime kilowatt-hour, but that edge is a coupon you only redeem by cycling it hard, and a 3kWh backup unit almost never gets cycled that hard. The EcoFlow does the same daily job for $420 less and hands off faster when the grid drops.
So buy the EcoFlow DELTA 3 Ultra and keep the difference, unless you already know you'll drain it daily or you want the extra 512Wh in the tank, in which case the Jackery HomePower 3600 Plus is the better machine and worth every dollar of the premium. Either way you're getting the same box to lift up the basement stairs; only one of you paid extra for cycles you'll outlive.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Jackery HomePower 3600 Plus worth $420 more than the EcoFlow DELTA 3 Ultra?
Only if you'll cycle it hard or you need the extra runtime. The Jackery is the bigger battery (3,584Wh to 3,072Wh) and the longer-lived one (6,000 cycles to 4,000), which makes it cheaper per lifetime kilowatt-hour, but that discount only pays off with the heavy, frequent cycling most backup units never see. For occasional backup and short trips, the EcoFlow covers the same loads, switches over faster, and saves you $420.
Which lasts longer, the DELTA 3 Ultra or the HomePower 3600 Plus?
The Jackery, on paper: its pack is rated for 6,000 charge cycles to the EcoFlow's 4,000. At a full cycle every day that's roughly 16 years against 11. Drop to a weekly cycle, though, and both run past 75 years, long beyond the point you'd retire the unit anyway, which is why this spec only matters to daily, heavy users.
Do the DELTA 3 Ultra and HomePower 3600 Plus weigh the same?
Effectively yes, both sit at 77.2 pounds. That's a two-hands, mind-your-back lift either way, and both include wheels and a telescoping handle for rolling across pavement. Weight is a genuine wash here, so don't let it into the decision.
Which has the faster UPS switchover for a computer or NAS?
The EcoFlow, at 10ms to the Jackery's 20ms. That puts the EcoFlow in line-interactive territory and the Jackery in standby, a difference sensitive electronics like a desktop mid-render, a NAS mid-write, or some medical gear can actually feel. For a fridge, lights, or a TV, both are fast enough that nothing notices the grid drop.
Which is better for solar and multi-day outages?
The Jackery leans that way. It accepts 2,000W of solar to the EcoFlow's 1,600W and holds a bigger 3,584Wh bank, so across a multi-day outage where you recharge from panels daily it both stores more and refills its larger battery in roughly the same window. Note that neither unit covers a full van-life day of about 4,685Wh on its own, which is expansion-plus-solar territory.
