Head-to-head test
EcoFlow DELTA 2 vs Jackery HomePower 1000 v2
Same 1,024Wh, same 5-year warranty, $70 apart — but the DELTA 2 runs at 50dB and wears out in half the cycles, while the HomePower 1000 v2 runs at 30dB and is rated for 6,000. The DELTA 2's $70 discount is the most expensive $70 on this page.

Spec deltas
The HomePower 1000 v2 is rated for 6,000 charge cycles; the DELTA 2 for 3,000. Buy the DELTA 2 and you own a battery that reaches the end of its rated life while the Jackery is barely halfway through its own, and the $70 the DELTA 2 saves you up front doesn't survive contact with that gap.
The two units are otherwise close cousins: identical 1,024Wh, identical 5-year warranties, near-identical power scores of 3,167 for the EcoFlow and 3,182 for the Jackery. The DELTA 2 hits back with 1,800W of continuous output against 1,500W, 500W of solar input against 400W, and an expansion port the sealed Jackery doesn't have.
But the DELTA 2 is the older, louder design, and the gap shows up in the two specs you live with every day. It runs at 50dB under load against the Jackery's 30dB, and its fan is the single most-cited complaint across more than six months of field reportsA1A2A4. For a box that sits in your bedroom or living room through a blackout, that isn't a footnote.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
It works out to $0.16 per lifetime kWh for the DELTA 2 against $0.09 for the Jackery — 6,144 kWh of rated life against 3,072, for $70 more today. The upfront discount is real; it's just smaller than the lifetime penalty stapled to it.
DELTA 2 costs $479 against the HomePower 1000 v2's $549DELTA 2 is rated for 3,000 cycles against the HomePower 1000 v2's 6,000
Why it mattersCycle the battery hard — daily off-grid, frequent outages — and the Jackery pulls ahead before the DELTA 2's warranty is even up. Only a light, occasional user gets to keep the $70.
The 20dB gap isn't a lab curiosity here. 50dB against 30dB is the difference between a working refrigerator and a whisper, and one reviewer's actual fix for the DELTA 2 was to run an extension cord out of the roomA1 — a fine solution unless you bought it for the room.
DELTA 2 runs at 50dB under load; the HomePower 1000 v2 at 30dBDELTA 2's fan spins up above roughly 120W and is its most-cited complaintA1A2
Why it mattersAnyone powering CPAP, a sound machine, or just sleeping near the unit should take the Jackery. Anyone parking it in a garage or truck bed will never hear the difference.
continuous output
That split is decided by your appliances. A 1,500W space heater runs on either, with more headroom on the DELTA 2; a fridge or well pump that draws a few hundred watts steady but slams hard at startup is the Jackery's kind of load. Neither ceiling is the reason to buy, since both fall short of a full weekend's 2,100Wh regardless.
DELTA 2 delivers 1,800W continuous against the HomePower 1000 v2's 1,500WThe HomePower 1000 v2 surges to 3,000W against the DELTA 2's 2,700W
Why it mattersMatch the unit to your heaviest appliance: sustained high draw leans DELTA 2, spiky compressor startups lean Jackery. If nothing you own tops 1,500W, it's a wash.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The crux — the Jackery costs $70 more but is cheaper to own ($0.09 vs $0.16/kWh) on double the cycles.
cost / lifetime kWh
$0.09 against $0.16 per lifetime kWh is the number that outlives the price tag. The Jackery costs $70 more today and hands it back as 3,072 more kWh of rated life, the same energy delivered at nearly half the cost per unit, because it's built for twice the cycles.
Cost per warranty-year runs the other way — $110 for the Jackery against $96 for the DELTA 2 — but that only reflects the higher sticker on identical 5-year terms. Past the warranty is where the cycle-life gap actually pays out, and it pays out to the Jackery.
What the Specs Don't Tell You
Selected because: Noise, UPS switchover, and surge are the daily-living specs that separate two otherwise-tied boxes.
rated cycles
Three of the specs here point the same direction. The Jackery switches over in 10ms against 20ms, line-interactive against standby, the difference between a desktop that never blinks and one that might. It surges to 3,000W against 2,700W. And it runs 20dB quieter.
The DELTA 2's counter is genuine: 300W more continuous output, 1,800W against 1,500W, real headroom for a space heater. But the card you'll actually notice is noise. 50dB is a fan you hear across a room, and it's the DELTA 2's most-documented quirkA1A2A4, not a spec-sheet edge case.
PowerScore Breakdown
Selected because: 15-point near-tie (3,182 vs 3,167) shows raw capability is a wash; decision lives elsewhere.
overall power score
15 points separate these two — 3,182 for the Jackery, 3,167 for the DELTA 2 — which is to say nothing separates them. The composite blends output, capacity, charging, and longevity, and in that blend the DELTA 2's output edge and the Jackery's cycle-life edge cancel almost exactly.
Which is the point. On raw capability these are the same box, and the decision lives entirely in the specs the score averages away: noise, cost-to-own, and whether you'll ever want to expand.
Growth Path
Selected because: The DELTA 2's expansion port is its one structural advantage the sealed Jackery can't answer.
solar input
The DELTA 2 holds one card the Jackery can't answer at any price: it takes an expansion battery. Start at 1,024Wh and add a second pack later without replacing the base unit.
For most 1kWh buyers that door never opens — you bought 1,024Wh because 1,024Wh was the job. But if you can see partial-home backup or longer off-grid stretches coming, the DELTA 2 grows toward them, and the sealed Jackery asks you to buy a whole second unit instead.
Brand Trust
Selected because: EcoFlow's ecosystem/app vs Jackery's retail reach and weak app — a real tiebreaker for daily users.
Neither support desk is a selling point, but they fail differently. EcoFlow has the deeper ecosystem and the larger community by far, alongside a support reputation that's genuinely split — some hassle-free replacements, some long waits and refurbished units. Jackery has the wider retail shelf, which is its own kind of warranty: a bad unit from Costco or Amazon is an in-person exchange, not a support ticket.
The apps aren't a wash. EcoFlow's rates well above 4 stars; Jackery's sits between 2.3 and 3.3 and makes you log in even offline. Touch the app daily and that gap is real; set it and forget it and it isn't.

Neither unit
Neither unit covers this scenario's 2,100Wh: the DELTA 2 comes up 1,230Wh short (about 41% covered), the HomePower 1000 v2 1,230Wh (41%). Treat this as partial cover — enough for the essentials in it, not the whole list.

Keep the essentials running through a night without power
Neither unit
Neither covers a full 8-hour whole-house blackout — both need nearly twice their 1,024Wh against about 1,645Wh of demand. For the partial outage they can cover, the Jackery's 10ms switchover keeps desktops and routers alive through the cutover where the DELTA 2's 20ms might drop them.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
HomePower 1000 v2
Both coast through a CPAP night at 37% of usable capacity, so capacity isn't the question — proximity is. Eighteen inches from your pillow, the DELTA 2's 50dB fan can make itself heard and the Jackery's 30dB won't. Coin-flip on paper, Jackery in the bedroom.

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 23.4 lbs the HomePower 1000 v2 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.

Conclusion
July 18, 2026
Verdict: the Jackery HomePower 1000 v2
The HomePower 1000 v2 wins on the things a 1kWh home-backup box is actually for. It's rated for 6,000 cycles against the DELTA 2's 3,000, runs at 30dB against 50dB, and switches over in 10ms against 20ms — and it costs $0.09 per lifetime kWh against $0.16. The DELTA 2's honest wins are narrower but real: $70 cheaper up front, 1,800W continuous against 1,500W, and an expansion port the sealed Jackery can't match. If you need that extra 300W or the room to grow, buy the DELTA 2 and cap its charge speed in the app to quiet the fanA2. Everyone else is buying the quieter box that lasts twice as long.

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 2 rates 4.4/5 (65th percentile of 24 Everyday-class units), and HomePower 1000 v2 rates 4.2/5 (52nd percentile of 24 Everyday-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.
The DELTA 2's One Loud Number
50dB against 30dB is the widest everyday gap between these two. The DELTA 2's fan triggers above light loads and runs audibly at full output; the Jackery stays near a whisper. If the unit lives where you sleep or work, this is the spec that decides it.
The Jackery's Sealed Ceiling
The HomePower 1000 v2 is fixed at 1,024Wh — no expansion, ever. The DELTA 2 can bolt on a second battery and grow. Held honestly against our pick: if you can see your needs climbing, the sealed box is the wrong one, and the Jackery is the sealed box.
Surge Power: Inverter Quality Indicator
The HomePower 1000 v2 has a 2× surge-to-continuous ratio vs the DELTA 2's 1.5×, and the higher absolute ceiling with it — 3,000W against 2,700W. A higher ratio (≥2×) means the inverter absorbs motor startup surges better, which matters for fridges, AC compressors, and power tools that briefly draw 2-3× their rated wattage. With both measures pointing the same way, the DELTA 2 is the one more likely to trip when starting these appliances.
10ms vs 20ms Switchover
The Jackery is line-interactive at 10ms; the DELTA 2 is standby-class at 20ms. Most gear rides through either. A desktop without its own battery, or a NAS mid-write, is where the 10ms actually earns its keep.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. Worth saying because the per-dollar framing can suggest otherwise: the DELTA 2 works out at 10 years of cover per $1,000 spent against the HomePower 1000 v2's 7.7, but that spread is the price gap, not the terms.
Twice the Cycles, Half the Price per kWh
6,000 rated cycles against 3,000 is why the pricier Jackery is the cheaper unit to own: $0.09 per lifetime kWh against $0.16. The DELTA 2's $70 discount is a one-time thing; the cycle-life gap pays out every recharge.

Brand trust
EcoFlow
Ecosystem
EcoFlow runs the deepest bench in portable power — a dozen-plus models and the largest owner community in the category, so accessories, expansion batteries, and answers are easy to find.
Support
Support is the polarized part: some buyers get hassle-free prepaid-label replacements, others wait and receive refurbished units. Buying through Costco or Amazon adds a return safety net the brand's own desk doesn't guarantee.
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
The Oct 2025 DELTA Max 2000 recall (overheating/fire risk, 6 incidents) is worth noting. Also 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
Jackery's edge isn't the spec sheet, it's the shelf — Costco, Home Depot, Best Buy, and Amazon all stock it, so a dead unit is often an in-person exchange instead of a support ticket.
Worth knowing
The app is the weakest of the major brands, rated 2.3 to 3.3, and makes you log in even offline. The HomePower line is also new enough that its support story isn't written yet.
Analyst note
EcoFlow gives you the bigger ecosystem and a support desk that's a genuine coin flip; Jackery gives you a thinner app and a wider retail shelf that quietly works as its best warranty. For a set-and-forget backup box, retail reach can matter more than either app.
Growth path
DELTA 2
EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 1,024Wh.
Accepts up to 500W of solar. Suitable for a 1-2 panel setup.
Generous port selection supports complex multi-device setups.
Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.
HomePower 1000 v2
FIXED CAPACITYFixed at 1,024Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 400W of solar. Suitable for a 1-2 panel setup.
Adequate ports for most setups, but heavy users may want a power strip.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
The HomePower 1000 v2 is sealed at 1,024Wh, which is fine if that covers you. The DELTA 2 starts at 1,024Wh and can grow beyond it with EcoFlow expansion batteries — though at this size expansion means longer runtimes on the same loads, not a path to home backup. More hours, not more house.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 2
The DELTA 2 has the one thing the Jackery can't yet have: a track record. Eighteen months of testing through outages, camping trips, and daily home-office use earned it consistent marks for fast charging and reliable LiFePO4 chemistryA3. It's a proven unit, not a launch-week guess.
The recurring gripe is the fan, and it's specific. It spins up above roughly 120W and runs continuously at full load, right around its 50dB ratingA1. While fast-charging it's been likened to a gaming laptop, though you can cap the charge speed in the app to quiet itA2. EcoFlow has said a firmware fix for fan behavior is plannedA4 — worth exactly what such promises usually are until it ships.
“When charging at 1200W the fans sound like a gaming laptop, though you can lower the charging speed in the app to silence it.”

Jackery HomePower 1000 v2
Field history on the HomePower 1000 v2 barely exists yet. It's a June 2026 SKU, and the only hands-on account so far is a single vendor-hosted test rather than accumulated ownershipB1, so read it with that caveat attached.
What that test did show was durability under abuse: it rode out days locked in a truck bed through 100-plus-degree heat, cycling up and down as a rolling fridge, without complaintB1, and the reviewer noted it felt more compact than the versions before itB5. Encouraging — but one summer test isn't the six months of outages the DELTA 2 already has behind it. On lifespan the spec sheet is the honest guide, and it says 6,000 cycles.
“It held up to many charging and discharging cycles as we topped it up at Superchargers, adding drinks and taking out food along the way — locked in the tonneau of a black truck driving through 100+ degree heat for days.”

Who Should Buy Which
Buy the DELTA 2 if you…
- →You want the lower sticker and the extra muscle — $479, 1,800W continuous, a real expansion port — and you're putting the unit somewhere its fan won't reach you: a garage, a truck bed, a job site.
- →You value a proven track record over a launch spec sheet. The DELTA 2 has a year and a half of field reports behind itA3; the Jackery has three weeks and one vendor test.
Buy the HomePower 1000 v2 if you…
- →You'll live near the unit while it works — bedroom backup, a CPAP two feet from your pillow, a home office — and 30dB against 50dB settles it before any other spec speaks.
- →You're keeping it a long time and cycling it often. 6,000 cycles at $0.09 per lifetime kWh is the cheapest energy on this page, and it stretches furthest for exactly the daily user.
If neither fits
If your real need is a full camping weekend (about 2,100Wh) or an 8-hour whole-house blackout (about 1,645Wh), both of these run out well short — each covers under half. Size up to a 2kWh-plus unit before choosing between these two 1,024Wh boxes.
The Bottom Line
The DELTA 2 saves you $70 and hands you 1,800W and an expansion port; the HomePower 1000 v2 charges $70 more and gives it back as twice the cycle life, half the noise, and $0.09-per-kWh energy that's the cheapest on the page. One is the better deal this afternoon. The other is the better deal every day after.
Buy the DELTA 2 if you need the output or the expansion and the fan won't reach your ears. Otherwise buy the quiet one still working when the DELTA 2's rated life runs out — for a box you'll live beside for a decade, that's the easy call.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Jackery HomePower 1000 v2 worth $70 more than the EcoFlow DELTA 2?
For most home-backup buyers, yes. The $70 buys twice the rated cycle life (6,000 against 3,000), a 20dB-quieter fan, and faster 10ms UPS switchover, and it comes out cheaper per lifetime kWh at $0.09 against $0.16. The DELTA 2 wins the value math only if you need its extra 300W of output or its expansion port, or you'll barely cycle the battery.
Which one is quieter?
The Jackery, decisively — 30dB against the DELTA 2's 50dB. The DELTA 2's fan is its single most-documented complaint, spinning up above about 120W and running loud at full load. You can cap its charge speed in the app to quiet it while recharging, but under heavy output it's audible across a room.
Can either run a CPAP overnight?
Both, easily — a CPAP night needs about 320Wh, roughly a third of either unit's 1,024Wh. The tiebreaker is noise: two feet from your pillow, the Jackery's 30dB is a non-issue, and the DELTA 2's fan may not be.
Can the DELTA 2 be expanded and the Jackery can't?
Yes. The DELTA 2 accepts an EcoFlow expansion battery to grow past its 1,024Wh; the HomePower 1000 v2 is sealed at 1,024Wh for good. If you expect your needs to climb toward partial-home backup, that expansion path is the DELTA 2's strongest card.
Is the DELTA 2's fan noise fixable?
Partly. You can lower the charge speed in the app to quiet it while recharging, and EcoFlow has said a firmware update to improve fan behavior is planned. But at high output the fan runs regardless, and the planned fix hadn't shipped as of this writing — treat the 50dB rating as what you're buying today.
