Head-to-head test
EcoFlow DELTA Pro vs Jackery Explorer 3000 v2
The DELTA Pro holds 528Wh more battery for $1,100 less, so the Jackery's case rests on two specifics: it's 39 pounds lighter and it doesn't carry the DELTA Pro's 60dB whine under load.

Spec deltas
The EcoFlow DELTA Pro holds more battery than the Jackery Explorer 3000 v2 and costs less to buy: 3,600Wh against 3,072Wh, at $1,399 to the Jackery's $2,499. That's 528Wh more storage for $1,100 less, which is not the direction price and capacity usually move together.
It presses that lead on the specs around the battery too: 1,600W of solar input to the Jackery's 1,000W, an expansion port the Jackery doesn't have, and a lower cost to own at $0.11 per lifetime kilowatt-hour against $0.20. The DELTA Pro is the older platform, a home-backup workhorse reviewers have run through months of outagesA1A3, and it shows in the value.
The Jackery's answer is physical. It's 39 pounds lighter, 59.52 to 99, and it doesn't come with the DELTA Pro's documented 60dB fan whine under heavy loadA4. Those are real advantages for a unit you carry or keep in a quiet room. For a box that lives in a basement and runs the fridge through a blackout, though, the DELTA Pro is more machine for less money.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
On a 2,100Wh camping weekend the DELTA Pro finishes at 69% used against the Jackery's 80%, so it holds more in reserve for the unplanned load, and it does it while costing $1,100 less. When more capacity and a lower price arrive in the same box, the burden shifts entirely onto the Jackery's non-capacity advantages to justify the premium.
DELTA Pro holds 3,600Wh at $1,399; Jackery holds 3,072Wh at $2,499The DELTA Pro wins the 2,100Wh Weekend Camping scenario outright, sitting at 69% of usable capacity to the Jackery's 80%
Why it mattersBuyers who rank storage and price first can take the DELTA Pro and stop; it wins both.
Rated at 60dB and confirmed to whine under sustained loadA4, the DELTA Pro is audible across a quiet room while it runs a heavy draw, though it calms down at light loads like a CPAP or a few devices. The Jackery doesn't disclose a number, so it's an unknown rather than a proven quiet, but the DELTA Pro's loudness is on the record. For a unit sharing your living space during a long outage, that's a real strike against the cheaper pick.

Why it mattersIf the unit runs heavy loads in a room you occupy, the noise-sensitive buyer should weigh the Jackery despite the price.
rated cycles
Multiply it out and the DELTA Pro delivers more total lifetime energy despite fewer cycles: about 12,600 kilowatt-hours to the Jackery's 12,288, because 3,600Wh across 3,500 cycles beats 3,072Wh across 4,000. The cycle-count edge the Jackery advertises doesn't survive contact with the capacity gap. Measured in energy rather than recharges, longevity tilts the other way.
Jackery is rated for 4,000 cycles; DELTA Pro for 3,500DELTA Pro capacity is 3,600Wh; Jackery is 3,072Wh
Why it mattersDon't pay the Jackery premium for its cycle rating; the DELTA Pro outlasts it on the number that matters, total energy.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: cheaperToOwn is p1 by a wide margin ($0.11 vs $0.20) and it also holds more capacity — the core of the verdict.
cost / lifetime kWh
The DELTA Pro is the cheaper unit to own by a wide margin: $0.11 per lifetime kilowatt-hour against the Jackery's $0.20. This is the uncommon case where the bigger battery is also the cheaper one, at the register and over time. It opens from a $1,399 price to the Jackery's $2,499, then extends the lead by storing 528Wh more energy every cycle. The Jackery's higher cycle count narrows that on paper without closing it; even in total lifetime energy the DELTA Pro finishes ahead, 12,600 kilowatt-hours to 12,288. Cheaper to buy, cheaper to run, and more storage besides.
Runtime: Will It Power Your Gear?
Selected because: 528Wh more capacity buys real extra hours on big loads; ties to the Jackery's fridge-runtime field notes.
The DELTA Pro's 528Wh of extra headroom shows up as hours on the loads that matter. A refrigerator is the clearest case: one Jackery owner ran a fridge past ten hours and still had roughly three-quarters of the battery leftB7, so both units carry a fridge deep into an outage, and the DELTA Pro's larger tank simply stretches it further. Where the runtime table flatters both is high-draw appliances; one owner warned that portable heaters drain the Jackery fastB8, and they'd drain the DELTA Pro nearly as quickly. Big steady loads reward the bigger battery. Short, heavy ones punish both, so size the unit to the appliance, not the headline capacity.
PowerScore Breakdown
Selected because: 5,483 vs 4,507 captures the capacity/solar/expansion lead the matched output/surge hides.
overall power score
Our PowerScore gives the DELTA Pro 5,483 to the Jackery's 4,507, and the gap is earned around the edges rather than the center. The two match on output (3,600W) and surge (7,200W), so the DELTA Pro builds its lead on 528Wh more capacity, 600W more solar intake, and an expansion path the Jackery lacks. What the composite doesn't dock it for is the two things the Jackery wins: noise, given the DELTA Pro's 60dB whine under loadA4, and cycle life, where the Jackery's 4,000 rating tops the DELTA Pro's 3,500. Read the score as 'more capable platform,' then let the noise and weight notes decide whether that platform belongs in your room.
Portability & Form Factor
Selected because: The Jackery's main edge: 39 lb lighter, but the DELTA Pro rolls on wheels — carry vs wheel.
weight
Weight is where the Jackery pushes back, and it's a real shove: 59.52 pounds against 99. But the DELTA Pro doesn't ask to be lifted so much as rolled, riding on integrated wheels and a telescoping handle that reviewers found work well on flat ground and less well on roughA2. So the honest framing isn't light versus heavy, it's carry versus wheel. The Jackery goes up stairs and into a trunk in your hands; the DELTA Pro crosses a garage floor on its casters and balks at a staircase. Match it to your terrain, not the raw pound count.
Brand Trust
Selected because: Cross-brand: EcoFlow's proven home-backup platform and huge community vs Jackery's retail reach and weak app.
EcoFlow's DELTA Pro is the most established home-backup platform in the category, backed by the largest owner community of any brand, which for a unit you lean on during outages means real troubleshooting help already exists. Support itself runs hot and cold, and there was an October 2025 recall on a different DELTA Max model, so buying from a retailer with a solid return window is the sensible hedge. Jackery answers with what it always does: the widest retail reach, the easiest return counter, and a name your neighbor recognizes. Its app remains the weakest of the majors. You're weighing EcoFlow's proven-platform depth against Jackery's buy-it-anywhere convenience.

DELTA Pro
A 2,100Wh weekend is the one everyday scenario where the DELTA Pro's bigger battery shows: it sits at 69% of usable capacity against the Jackery's 80%, finishing with more in reserve. Both clear the weekend comfortably, but the DELTA Pro's 3,600Wh leaves more headroom for the unplanned extra load. More battery, more margin, less money.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP is about 40W for eight hours, so both cover the night with room to spare and capacity decides nothing. Fan noise would — but Explorer 3000 v2 doesn't publish a figure, so there's nothing to hold it to. Buy on price, weight, and whether you can live with a fan you haven't heard.

Either unit
Both handle game day easily. Since capacity isn't the deciding factor, weight is: at 59.5 lbs the Explorer 3000 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.

Neither unit
A 4,685Wh day is past both batteries, but the DELTA Pro gets closer and can keep going. Its 3,600Wh base covers more of the day than the Jackery's 3,072Wh, and its expansion port can add the rest, where the Jackery is fixed. For full-time off-grid living, the DELTA Pro is the platform to build on, or step up a class entirely.

Conclusion
July 18, 2026
Verdict: the DELTA Pro
The DELTA Pro is the value-and-capacity pick, and the Jackery is the quiet, portable one you pay extra for. The DELTA Pro holds 3,600Wh to the Jackery's 3,072Wh, costs $1,399 against $2,499, takes more solar (1,600W vs 1,000W), and expands, which puts it at $0.11 per lifetime kilowatt-hour to the Jackery's $0.20. It even out-delivers the Jackery on total lifetime energy, about 12,600 kilowatt-hours to 12,288, despite a lower 3,500-cycle rating. What it isn't is quiet or light: 99 pounds to the Jackery's 59.52, and a 60dB fan that whines under heavy loadA4. For home backup that stays put, the DELTA Pro does more for less. If you carry the unit or keep it in a quiet room while it works, the Jackery's lighter, calmer package is worth the premium.

Hidden gotchas and advantages we spotted that you won't find on the product page.
99 pounds, but on wheels
The DELTA Pro weighs 99 pounds to the Jackery's 59.52, so on paper the Jackery is far easier to move. The nuance is the wheels: the DELTA Pro rides on integrated casters with a telescoping handle, so on flat ground you roll it rather than lift it. Stairs and rough terrain are where the 39-pound gap turns real. For a basement-to-garage life it's a non-issue; for a second-floor carry, buy the Jackery.
The honest knock on our pick
The DELTA Pro is rated 60dB, and reviewers describe a high-pitched fan whine when it's pushed hard, the kind that carries in a still room. That's the real cost of its lower price. At light loads it settles down, so a CPAP or a few devices won't set it off, but run a heavy load in a shared space and you'll hear it. If quiet-under-load is non-negotiable, that's the reason to look past the value and at the Jackery.
Explorer 3000 v2: Fixed Capacity
The Explorer 3000 v2 is sealed at 3,072Wh — fine if that covers you, but it's the ceiling. By contrast the DELTA Pro can add expansion batteries, so if your needs grow past 3,072Wh it has somewhere to go the Explorer 3000 v2 doesn't — and at this size that path genuinely points toward partial-home backup.
Same five years, lower yearly cost
Both carry a five-year warranty, but spread across those years the DELTA Pro works out to $280 annually against the Jackery's $500. Same coverage window, a good deal less per year, because it's wrapped around a unit that costs $1,100 less up front.
One publishes, one doesn't
Unusually, the disclosed noise number here belongs to the louder trait: the DELTA Pro owns its 60dB rating, while the Jackery lists no figure at all. Knowing the DELTA Pro reaches 60dB under load is more useful than the Jackery's silence on the question, even when the number itself isn't flattering. Buy on what's measured, not on what's left blank.

Analyst note
The DELTA Pro wins on both sticker price and long-term value. At $0.15/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner. One caution on the lifespan row: the Explorer 3000 v2 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the DELTA Pro still delivers more over its shorter horizon (12,600 vs 12,288 kWh). Years measure wear, not usefulness.
Brand trust
EcoFlow
Ecosystem
The deepest lineup in portable power, and the DELTA Pro is its home-backup workhorse, one of the most established platforms in the category with a large expansion ceiling.
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
The largest owner community of any brand, tens of thousands strong on Reddit alone, which for a home-backup unit means real troubleshooting help when something goes sideways.
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
EcoFlow's support runs hot and cold, and there was an October 2025 recall on a different DELTA Max model, so buying from a retailer with a good return window is the usual hedge.
Jackery
Ecosystem
A dozen-plus models across the Explorer and HomePower lines, with the broadest retail distribution in the business.
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
Familiarity and reach: the power station you can buy in person at Costco or Best Buy and return without a fight.
Worth knowing
The app is the weakest of the majors, and this SKU has reportedly been succeeded by the HomePower 3000, so confirm you're buying current stock.
Analyst note
EcoFlow brings a proven home-backup platform, a bigger battery, deep expansion, and a large owner community, at $1,100 less. Jackery brings a lighter body, a quieter spec sheet under load, and the easiest return counter around. For a unit that stays home and works, EcoFlow; for one you carry or keep close, Jackery has a genuine case.
Growth path

Analyst note
The Explorer 3000 v2 is sealed at 3,072Wh, which is fine if that covers you. The DELTA Pro starts at 3,600Wh and can grow beyond it with EcoFlow expansion batteries — real headroom the Explorer 3000 v2 doesn't have if your needs climb toward partial-home backup.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA Pro
The DELTA Pro is the veteran in this pair, a long-standing home-backup platform reviewers treat as a known quantity: built for high-draw appliances and full-scale expansion, run as primary backup through months of overnight outagesA1A3. Two caveats travel with it. It's heavy but wheeled, with an integrated handle and casters that work on flat ground and struggle on roughA2, and it isn't quiet under load, where reviewers note the fans throw a high-pitched whine when pushed hard that carries in a still roomA4. Note that much of the DELTA Pro-line coverage blends the original with the newer Pro 3, so trust the general traits, home-backup focus, wheels, big expansion, and load noise, more than any single measured figure from a review.
“Long regarded as a gold standard for home backup — designed for high-draw appliances and full-scale battery expansion, running home essentials like a fridge, lighting, and a space heater through outages.”

The Jackery's field notes center on runtime that reassures. One owner ran a refrigerator past ten hours and still had roughly three-quarters of the battery leftB7, and T3's reviewer couldn't find a home appliance short of a Miele oven it wouldn't runB2. The counterweights are honest. High-draw items like portable heaters drain it fastB8, TechRadar wanted more than its outlet count and flagged the lack of a rugged rating for constant outdoor useB9, and reviewers consistently note the proprietary DC8020 solar socket that won't take third-party panels without an adapterB3B10. It's also sealed at its rated capacityB4, and this SKU has reportedly been succeeded by the HomePower 3000.
“This particular model is most definitely a lot lighter — and smaller — than anything else I've seen with this level of performance...I can actually carry it from room to room without a visit to the chiropractor.”

Who Should Buy Which
Buy the DELTA Pro if you…
- →The home-backup buyer who wants the most battery for the money: 3,600Wh for $1,399, $1,100 under the Jackery and with 528Wh more capacity.
- →The buyer who'll expand: EcoFlow batteries push the DELTA Pro toward whole-home backup, where the Jackery is capped.
- →The solar user: 1,600W of intake to the Jackery's 1,000W.
- →Anyone who parks it and rolls it: the weight lives on wheels, so it moves without a lift, just not up stairs.
Buy the Explorer 3000 v2 if you…
- →The buyer who carries it: 59.52 pounds you lift in one trip, versus a 99-pound roll that hates stairs.
- →The quiet room under sustained load: the DELTA Pro is rated 60dB and whines under heavy drawA4, so if the unit shares your space while working hard, the Jackery's calmer profile matters.
- →The shopper who wants retail familiarity and an easy return, and will pay $1,100 for the lighter body and the recognizable name.
If neither fits
If your target is the 4,685Wh van-life day, neither box finishes it, though the DELTA Pro's bigger battery and expansion get closer. And if you want quiet, light, and 3kWh-plus all at once, this pair makes you pick two of the three, so look at a newer LFP unit that carries neither the DELTA Pro's fan nor the Jackery's price.
The Bottom Line
The DELTA Pro is the value-and-capacity pick: 3,600Wh for $1,399, a full $1,100 under the Jackery and with 528Wh more battery, plus more solar and room to expand. It even out-delivers the Jackery on total lifetime energy despite a lower cycle rating. For home backup that stays put and rolls when it must, that's the stronger and the cheaper machine.
The Jackery earns its premium on two specifics: it's 39 pounds lighter, 59.52 to 99, and it doesn't carry the DELTA Pro's 60dB whine under loadA4. If you lift the unit or keep it in a quiet room while it works, those are worth paying for. If it lives in a basement and runs your fridge through outages, the DELTA Pro does more for less.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow DELTA Pro or the Jackery Explorer 3000 v2 the better buy?
The DELTA Pro for value and capacity, the Jackery for weight and quiet. The DELTA Pro is $1,399 to the Jackery's $2,499, with 528Wh more battery (3,600Wh vs 3,072Wh), more solar, and expandability, so it's more storage for $1,100 less. The trade-offs are real: it's 99 pounds to the Jackery's 59.52 and rated at 60dB under load. For home backup, take the DELTA Pro; for a unit you carry or keep in a quiet room, the Jackery.
Which one lasts longer?
By cycles, the Jackery, at 4,000 to the DELTA Pro's 3,500. By total energy delivered, the DELTA Pro, because its bigger 3,600Wh battery works out to about 12,600 lifetime kilowatt-hours against the Jackery's 12,288. So the Jackery recharges more times, but the DELTA Pro pushes more power over its life. On the measure that actually powers your loads, the DELTA Pro edges it.
Is the DELTA Pro too loud for a bedroom?
Under heavy load, possibly. It's rated 60dB and reviewers describe a high-pitched fan whine when it's working hard, which carries in a quiet room. At light loads like a CPAP or a few devices it's much calmer. The Jackery publishes no noise figure, so it's an unknown, but the DELTA Pro's loudness under sustained draw is a documented trade for its lower price.
Which is better for camping and travel?
The Jackery, mostly on weight: 59.52 pounds you carry in one trip against the DELTA Pro's 99, which rolls on wheels but doesn't lift easily. The DELTA Pro holds more energy and costs less, so for car camping where you don't move it far it's still viable. For anything with a trail, stairs, or a long carry, the Jackery's lighter body wins.
