Head-to-head test
EcoFlow DELTA 3 Ultra Plus vs Jackery Explorer 3000 v2
The same 3,072Wh battery sits in both, but the EcoFlow is $1,000 cheaper, takes 600W more solar, and switches over twice as fast, so the Jackery's entire case is 17.68 fewer pounds to lift.

Spec deltas
The EcoFlow DELTA 3 Ultra Plus costs $1,000 less than the Jackery Explorer 3000 v2 and carries the identical 3,072Wh battery, the same 3,600W inverter, the same 7,200W surge, and the same 4,000-cycle rating. On the numbers that define what a power station actually does, these two are the same unit at two prices.
Where they part, the EcoFlow leads almost everywhere. It takes 1,600W of solar to the Jackery's 1,000W, so it refills from empty in roughly two hours of strong sun against about three. It switches over in 10 milliseconds to the Jackery's 20, the difference between a desktop that never notices the grid drop and one that might. And it can bolt on an expansion battery, where the Explorer is sealed at 3,072Wh for good.
The Explorer 3000 v2 answers with one number: 59.52 pounds, against the EcoFlow's 77.2. That 17.68-pound gap is the line between a one-person lift and a two-person, bent-knee haul, and for a unit you carry it's worth something. For $1,000, though, it's worth something to a narrow group, the people who move this box often. Everyone else is buying weight relief they'll feel a few times a year and paying for it every day they owned the cheaper unit instead.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
So the Jackery premium buys zero additional power over the life of the unit. The EcoFlow even takes 1,600W of solar to the Explorer's 1,000W, meaning it refills faster too. Every dollar of that $1,000 is going somewhere other than capacity, output, or cycles, because those three are dead even.
EcoFlow $1,499 vs Jackery $2,499 for the same 3,072Wh and 4,000 cyclesBoth deliver 12,288 kWh of lifetime energyEcoFlow $0.12 per lifetime kWh vs Jackery $0.20
Why it mattersIf cost is your axis, the decision is over before you weigh anything else: same energy, $1,000 less.
Weight only charges you when the unit moves. Hauled to a campsite most weekends, the Jackery's lighter frame earns real goodwill against a box reviewers call a two-person liftA9. Parked in a closet for blackouts, those 17.68 pounds never move and the $1,000 you saved never stops mattering.

Why it mattersBuy the Jackery only if you personally carry this unit often; the backup buyer should pocket the difference.
solar input
A 10-millisecond line-interactive switch holds up a desktop or a CPAP that a 20-millisecond blink could reboot, the extra 600W of solar shaves an hour off a sun-only recharge, and the expansion port lets the EcoFlow pass 3,072Wh later while the Jackery can't. None of these is decisive alone. Stacked on top of the $1,000, they stop being close.

Why it mattersOff-grid users, CPAP owners, and anyone who might grow the system get more from the cheaper unit.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: Same 3,072Wh battery, $1,000 apart, cheaperToOwn is p1 ($0.12 vs $0.20) — the backbone of the verdict.
cost / lifetime kWh
The lifetime ledger isn't close, and it isn't subtle. Both boxes hold 3,072Wh and carry a 4,000-cycle rating, so both hand you the same 12,288 kWh across their lives. The EcoFlow gets there for $1,499 and the Jackery for $2,499, which pencils out to $0.12 per lifetime kilowatt-hour against $0.20. Same energy, same warranty length, $1,000 apart.
Measured per warranty year, the EcoFlow costs $300 to the Jackery's $500. There is no runtime edge, no extra port, and no additional coverage on the Jackery side of that ledger to win the money back. You are paying more for the same battery and getting slightly less around it.
Portability & Form Factor
Selected because: The Explorer's only genuine win: 17.68 lb lighter. Must be honored honestly, then priced.
weight
This is the Explorer's section, and it's the only one it wins. At 59.52 pounds it's a genuine one-person carry; the EcoFlow, at 77.2, is a two-hands, bend-at-the-knees lift that reviewers describe as punishing to moveA9. If your use is weekend camping or anything that rides in and out of a trunk, 17.68 pounds off the top is a real, repeated relief.
The honest question is what you paid for it. The Jackery charges $1,000 for that lighter frame and gives back solar input, switchover speed, and expandability to fund it. For the frequent hauler that trade can pencil out. For the person whose unit lives on one floor, it's a lot of money for a lift you rarely make.
PowerScore Breakdown
Selected because: 5,220 vs 4,507 — explain the 713-point gap comes from solar/UPS/expansion/price, not the tied battery.
overall power score
Our PowerScore puts the EcoFlow at 5,220 to the Explorer's 4,507, a 713-point gap between two units with the same battery, inverter, and surge. The score isn't measuring output here, because output is a tie at 3,600W. It's measuring the edges: 1,600W of solar to 1,000W, a 10-millisecond switchover to 20, an expansion path against a sealed box, and a lower price.
Strip the shared battery out of the comparison and everything left points the same direction. The number is just the price tag and the spec sheet agreeing with each other.
Growth Path
Selected because: EcoFlow expandable vs Explorer sealed; engine gives the growth edge to p1.
solar input
The EcoFlow can grow and the Explorer can't, and that asymmetry sits underneath the whole matchup. Both start at 3,072Wh. The DELTA 3 Ultra Plus accepts an expansion battery, so if your needs climb toward partial-home backup you add capacity instead of replacing the unit. The Explorer 3000 v2 is sealed at 3,072Wh, a complete system with no port to grow into.
For plenty of buyers that ceiling never bites; 3,072Wh already covers a weekend, a blackout, and every scenario here short of full van-life draw. But if there's any chance your load grows, only one of these two follows you there, and it's also the cheaper one. That combination is hard to argue against.
Brand Trust
Selected because: Cross-brand: EcoFlow's deep ecosystem and a recall to note vs Jackery's recognition, weak app, and short SKU life.
EcoFlow brings the deepest ecosystem in portable power and the fastest charging tech, plus an app reviewers actually praise for features like weather-triggered top-upsA12. The asterisks are real: support experiences are polarized, and there's an October 2025 recall affecting a separate model in the DELTA Max range worth knowing about before you buy the brand. A retailer with a generous return window is the standard hedge.
Jackery counters with the strongest name recognition in the category and the widest shelf presence, the closest thing to a default brand. The costs show up in the software, where its app rates the weakest of the majors, and in this SKU's short shelf life. If brand familiarity and buying it in a store you already trust matter most, the Jackery is the comfortable pick. It's just the more expensive road to the same 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
Either unit
Both hold 3,072Wh and both cover a 2,100Wh weekend with the same headroom, so power is a dead tie here. The decision is physical. The Jackery is 17.68 pounds lighter to carry from the car to the site; the EcoFlow refills faster between days on its bigger solar input and cost $1,000 less to buy. Carry it far and the Jackery earns its keep. Recharge by sun and mind the budget, and the EcoFlow does.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP pulls about 320 watt-hours overnight, roughly a tenth of either battery, so capacity is irrelevant and both coast to morning. Eighteen inches from your head, the specs that matter are noise and switchover. The EcoFlow publishes a 30-decibel figure and testers found it near-silent, while Jackery lists no noise number at all, and the EcoFlow's 10-millisecond switch is less likely than a 20-millisecond one to reboot the machine if the grid flickers. The quieter, faster-switching unit is the one to keep by the bed.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh

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 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.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
This is the one scenario neither box finishes. Van-life daily draw runs near 4,685Wh, and 3,072Wh covers only part of it before you're recharging. The tiebreak in a losing scenario is which unit can stop losing: the EcoFlow takes an expansion battery to close the gap, and the Explorer is sealed. If this is your real load, the EcoFlow is the only one of the two with a path to it, and you'll still want to plan capacity from day one.

Conclusion
July 18, 2026
Verdict: the DELTA 3 Ultra Plus
Buy the EcoFlow DELTA 3 Ultra Plus. It's the same 3,072Wh, 3,600W machine as the Explorer 3000 v2, with the same 4,000-cycle rating and the same five-year warranty, but it costs $1,499 to the Jackery's $2,499 and works out to $0.12 per lifetime kilowatt-hour against $0.20. It also takes 1,600W of solar to the Explorer's 1,000W, switches over in 10 milliseconds to 20, and can add an expansion battery the sealed Jackery can't. The Explorer wins exactly one spec that matters: weight, at 59.52 pounds to the EcoFlow's 77.2. That 17.68-pound gap is real if you haul the unit to campsites every weekend. If it lives in a closet for backup, you're paying $1,000 more for less of everything else. One footnote worth knowing: Jackery appears to have already replaced the Explorer 3000 v2 with the cheaper HomePower 3000, so this is a premium price on a short-lived SKU.

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 Explorer 3000 v2 rates 3.9/5 (33rd percentile of 25 Large-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 heavy one is the cheap one
The EcoFlow is the two-person lift here at 77.2 pounds, and the Explorer's 59.52 is its single clearest advantage. Worth being honest about: if you carry this unit often, that 17.68-pound gap is real and repeated. It just arrives attached to the more expensive unit, which is the reverse of how weight penalties usually price out.
Explorer 3000 v2: Fixed Capacity
The Explorer 3000 v2 is sealed at 3,072Wh — a complete unit, and already larger than the DELTA 3 Ultra Plus's 3,072Wh. By contrast the DELTA 3 Ultra Plus can add expansion batteries, but that only pulls ahead if you'd grow past 3,072Wh.
10 milliseconds against 20
The EcoFlow runs a line-interactive switchover at 10 milliseconds; the Jackery uses a standby design at 20. For a fridge or a phone charger the difference is invisible. For a desktop workstation or a CPAP, the faster, always-conditioned path is the one less likely to drop the load when the grid hiccups.
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 3 Ultra Plus works out at 3.1 years of cover per $1,000 spent against the Explorer 3000 v2's 2, but that spread is the price gap, not the terms.
One prints a number, one doesn't
EcoFlow publishes 30 decibels for this unit and independent testers back it up as genuinely quiet under load. Jackery lists no noise figure for the Explorer 3000 v2 at all. A blank spec isn't proof of a loud fan, but on a $2,499 unit you'd rather read the number than infer it from a rival's.

Analyst note
The DELTA 3 Ultra Plus wins on both sticker price and long-term value. At $0.13/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner. 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
The broadest lineup in portable power, from RIVER 3 up to DELTA Pro, with the fastest charging tech in the category and expansion batteries across the range.
Support
US-based, but experiences split hard, from painless prepaid-label replacements to long waits and refurbished units on new claims. Buying from Costco or Amazon gives you a stronger return backstop.
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 app earns real praise for features like weather-triggered charging, but there's an October 2025 recall affecting a separate model in the DELTA Max range worth a look before you commit to the brand.
Jackery
Ecosystem
The widest retail presence and highest name recognition in the category, spanning Explorer portables and HomePower home-backup units, plus the SolarSaga panels.
Support
US-based but widely criticized for slow, scripted responses and strict receipt requirements. As with EcoFlow, a Costco or Amazon purchase is the safer route for returns.
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
The app is the weakest of the major brands, and this specific model looks like a short-timer: Jackery appears to have replaced it with the cheaper HomePower 3000.
Analyst note
EcoFlow is the value-and-features pick here, cheaper and deeper, with a polarized support record and a recall on a different model to note. Jackery is the recognition-and-retail pick, easy to buy in a store you trust, but you're paying more for a weaker app and a battery its own successor now sells for less. Same cells, two very different value propositions.
Growth path

Analyst note
The Explorer 3000 v2 is sealed at 3,072Wh, which is fine if that covers you. The DELTA 3 Ultra Plus starts at 3,072Wh 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

EcoFlow DELTA 3 Ultra Plus
Reviewers keep landing on how quiet this thing is. Even pushed hard, testers put its fan noise near EcoFlow's premium DELTA Pro Ultra and well below older DELTA modelsA1A2, and one measured it near-silent under sustained loadA13. The build backs the price, with nothing cheap or fragile about the shell, buttons, or cable, plus moisture resistance and tolerance for a short dropA8A14.
The value story has a twist testers flagged: at its original list price the unit was hard to justify, but at the street price it actually sells for, the math swings sharply in its favorA10A11. In use, one reviewer worked a full eight-hour day of laptop, desktop, and monitors and still had power to spareA5, and another noticed no dip at all when the wall power was pulled, confirming the pass-through works as billedA6. This is a recent release, so the record is professional testing over weeks, not years of owner reports yet.

“I'm also disappointed that it isn't compatible with any other type of third-party solar panel, and Jackery doesn't include any kind of adaptor.”

“Given the amount of power here, more than three mains outlets would be ideal, and without a rugged rating, it's difficult to recommend for those consistently using it outdoors.”

Who Should Buy Which
Buy the DELTA 3 Ultra Plus if you…
- →The value buyer: the same 3,072Wh and 4,000 cycles as the Jackery for $1,000 less, and the cheaper unit to own at $0.12 per lifetime kWh.
- →The off-grid recharger: 1,600W of solar refills it in roughly two hours of good sun, against the Jackery's 1,000W and about three.
- →The CPAP or desktop user: a 10-millisecond line-interactive switchover holds the load through a grid drop the Jackery's 20-millisecond standby might blink on.
- →Anyone who might grow later: it takes an expansion battery the sealed Explorer can't.
Buy the Explorer 3000 v2 if you…
- →The frequent hauler: 59.52 pounds is a one-person carry, 17.68 under the EcoFlow, and if you move it constantly that's worth real moneyB1.
- →The brand-loyal in-store buyer who wants a Jackery off a shelf they trust and will mostly leave it parked.
If neither fits
If your target is van-life daily draw near 4,685Wh, neither 3,072Wh box finishes the day. The EcoFlow can expand toward it; the Jackery can't. Either way, budget for more capacity from the start or step up a class. And if you like the Jackery but not the price, its own cheaper successor, the HomePower 3000, runs the same battery for far less.
The Bottom Line
Buy the EcoFlow DELTA 3 Ultra Plus. It's the same 3,072Wh, 3,600W battery as the Explorer 3000 v2, with the same 4,000 cycles and the same five-year warranty, for $1,000 less and a lower $0.12 per lifetime kilowatt-hour. It also takes more solar, switches over faster, and can grow. The Jackery's one honest win is 17.68 pounds of weight relief.
That relief is worth paying for if you carry this unit often. If you don't, you're spending $1,000 to make a lift you rarely perform slightly easier, while giving up solar speed, switchover, and expandability to do it. For the camper who hauls it every weekend, look hard at the Jackery. For everyone else, the cheaper EcoFlow is the same battery and more unit.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow DELTA 3 Ultra Plus or the Jackery Explorer 3000 v2 the better buy?
The EcoFlow, for most people. It's $1,499 to the Jackery's $2,499 and holds the identical 3,072Wh battery, 3,600W inverter, and 4,000-cycle rating, so you're getting the same performance for $1,000 less. It also takes more solar and switches over faster. The one reason to choose the Jackery is weight: it's 17.68 pounds lighter.
Why is the Jackery more expensive if the specs are the same?
Mostly brand, and for this model a short window on the market. The Explorer 3000 v2 carries Jackery's name-recognition premium, and it appears to have already been succeeded by the cheaper HomePower 3000. On paper you're paying $1,000 more for a lighter chassis and a slightly slower everything-else.
Is the EcoFlow's faster UPS switchover worth caring about?
For a desktop workstation, a CPAP, or a home server, yes. The EcoFlow switches in 10 milliseconds on a line-interactive design; the Jackery uses a 20-millisecond standby switch. Both are quick, but the faster, always-conditioned path is less likely to let a sensitive device reboot during a grid blip. For charging phones and running a fridge, neither will ever bother you.
Which one should I buy for weekend camping?
If you carry it far from the car, the Jackery's 59.52 pounds beats lugging the EcoFlow's 77.2. If you car-camp and recharge by solar, the EcoFlow's 1,600W refills faster and costs $1,000 less to get. Both hold the same 3,072Wh, so it comes down to whether the 17.68-pound difference is worth the money to you.
Can either one power my whole house during an outage?
Neither is a whole-home system, but both cover essentials. Their shared 3,072Wh runs a fridge, lights, internet, and phones through an 8-hour blackout with room left, using about 63 percent of the battery. For central AC or a well pump across a multi-day outage you'd want more, and only the EcoFlow can expand toward it.
