Spec deltas
The Jackery HomePower 3600 Plus stores 3,584Wh to the EcoFlow DELTA 2 Max's 2,048Wh — 1,536Wh more, enough to turn a unit that comes up just short of a weekend of camping into one that clears it with room to spare.
That capacity is the Jackery's headline, but it isn't free. The HomePower weighs 77.2 pounds to the DELTA's 50.7 — 26.5 pounds that put wheels and a pull handle on the JackeryB2 and a two-hands-under-the-lip lift on the EcoFlow. It also costs $322 more up front.
Both are LiFePO4, both carry a five-year warranty, both expand. The decision isn't build quality. It's whether you'll actually consume the Jackery's extra 1,536Wh and its 6,000-cycle life, or pay to haul capacity you never touch.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
The Jackery clears the same weekend using about 69% of its bank and still holds 1,484Wh in reserve for a second trip or a bad-weather day. The EcoFlow's shortfall isn't dramatic, but it's the line between planning around the battery and forgetting it's there.

Why it mattersIf your longest single draw runs past 2,000Wh, the Jackery is the one that stops making you ration.
rated cycles
The eight-cent number only arrives if you cycle the Jackery deep into its 6,000-cycle life, roughly sixteen years of daily use. Inside the five-year window either unit will actually see, the cheaper-to-buy DELTA is also the cheaper-to-own one.

Why it mattersDon't let the lifetime-kWh figure close the deal; it's only real for a buyer who'll still own this a decade and a half from now.
solar input
From empty, 2,000W of panels push the Jackery's 3,584Wh back to full in one strong afternoon; the DELTA's 1,000W ceiling means its smaller 2,048Wh bank still needs most of a good solar day. In a multi-day outage, the bigger unit is also the faster one to bring back.

Why it mattersOff-grid or in a long blackout, the Jackery's solar ceiling matters more than its extra weight.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Capacity split only resolves against real loads — camping is the one true capability gap.
One scenario actually separates these two, and it's camping. A 2,100Wh weekend leaves the 2,048Wh DELTA 52Wh short and the 3,584Wh Jackery sitting at 69% with a night to spare. Every lighter load — a CPAP at a fraction of either bank, a workday at the desk, a tailgate — both units clear without breaking a sweat, so the extra Jackery capacity there is headroom you're paying for, not using.
The honest exception is back-to-back nights. Either unit runs an 8-hour essentials blackout — the DELTA at 94% of its usable bank, the Jackery at 54% — but only the Jackery starts the second night with meaningful reserve. If your outages come one evening at a time, the DELTA is enough; if they come in threes, the Jackery is the one you're not recharging in the dark.
Lifetime Value
Selected because: cheaperToOwn favors Jackery on lifetime kWh but DELTA wins per warranty year; must be shown honestly.
cost / lifetime kWh
This is where the Jackery's best number and the DELTA's best number point in opposite directions, and both are true. Per lifetime kilowatt-hour the Jackery is eight cents to the EcoFlow's twenty-one — a real gap that comes straight from holding more energy across twice the cycles. Per warranty year, though, the cheaper-to-buy DELTA also costs less to keep: $259 against $324.
The reconciliation is the horizon. The eight-cent figure assumes you cycle the Jackery through 6,000 charges — a decade and a half of daily use almost nobody reaches. If you're a weekends-and-outages owner, price the two by what you'll pay in the years you'll own them, and the DELTA is the cheaper unit. If you're genuinely buying for the next fifteen years of daily cycling, the Jackery earns its lifetime math.
Portability & Form Factor
Selected because: 26.5 lb gap is the DELTA's main card; wheels mitigate it for the Jackery.
weight
The spec sheet says 26.5 pounds separate these, and the floor says less. The Jackery's 77.2 pounds ride on built-in wheels and a pull handle, so on a flat path you tow itB2; the DELTA's 50.7 pounds have no wheels, so every pound is in your hands. On smooth ground the heavier unit is the easier one to move.
Stairs flip it. Wheels do nothing on a basement staircase, where the DELTA's lighter dead-lift wins and the Jackery becomes a two-person job. Match the unit to your route, not to the number: rolling across a garage favors the Jackery, carrying up to a second floor favors the EcoFlow.
Growth Path
Selected because: Both expand; Jackery's 2,000W solar ceiling is the stronger off-grid growth story.
solar input
Both units take expansion batteries, so neither boxes you in — the difference is how fast the bigger setup refills. The Jackery's 2,000W solar ceiling is double the DELTA's 1,000W, which matters the moment you start adding panels rather than capacity. A larger bank you can only trickle-charge is a slower unit; the Jackery avoids that.
For an off-grid build that will grow, the higher solar ceiling is the quieter but more decisive advantage. Capacity you can add to either; the ability to put that capacity back before sundown is where the Jackery's growth path is genuinely stronger.
Brand Trust
Selected because: EcoFlow ecosystem/app vs Jackery retail reach and return safety net.
EcoFlow brings the deeper ecosystem and the better software — the widest accessory and expansion path in portable power, and a well-rated app. Jackery brings the name your neighbor recognizes and the shelf space to match: Costco, Home Depot, Best Buy.
The practical tiebreaker is the return counter. Both brands draw mixed support reports, so buying either through a retailer with its own return policy is the real safety net here — and Jackery's retail reach makes that easy.

Weekend Camping
Two nights off-grid with essential comfort
HomePower 3600 Plus
The Jackery clears a 2,100Wh weekend using about 69% of its bank; the DELTA lands 52Wh short at 2,048Wh — close enough to make the trip, tight enough to ration the last night. If camping is why you're buying, that gap is the whole decision.

Keep the essentials running through a night without power
HomePower 3600 Plus
Both keep the essentials on. The DELTA covers the 1,645Wh evening at 94% of its usable bank, the Jackery at 54% with a full second night in reserve. For a single outage the DELTA is enough; for back-to-back nights the Jackery keeps you from recharging in the dark.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Both are wildly overqualified for CPAP. You're using 18% or less. Save your money and buy whichever is cheaper; the extra capacity is completely wasted on a 40W overnight load. Put the savings toward a second battery for multi-night trips.

Game day power for the crew
HomePower 3600 Plus
Both handle game day, and the HomePower 3600 Plus does it with more in reserve — 22% used against 38%. Tailgating is a light load, so that headroom counts for less here than the 26 lbs you'll actually carry across the parking lot.

Neither unit
Neither one gets you there. A full off-grid day runs about 4,685Wh — past the Jackery's 3,584Wh and well past the DELTA's 2,048Wh. This is a two-battery or 5kWh-class job; don't buy either expecting to cover it.

Conclusion
July 16, 2026
Verdict: the HomePower 3600 Plus, on Power Score margin
The HomePower 3600 Plus is the more capable box — 3,584Wh to 2,048Wh, 6,000 cycles to 3,000, 2,000W of solar to 1,000W — and at eight cents per lifetime kilowatt-hour against twenty-one, it's cheaper to own if you actually cycle it for a decade. It's also $322 more, 26.5 pounds heavier, and over the five-year warranty both share it costs $324 a year to the EcoFlow's $259. Take the Jackery if you need to clear a weekend of camping at 2,100Wh or want a home-backup reserve you won't outgrow. If your real loads — an evening blackout, a CPAP, a workday at the desk — sit under 2,000Wh, the DELTA 2 Max does the same job lighter and for less money.

77 Pounds, But on Wheels
The Jackery's 77.2 pounds sound like a two-person lift, and picked up dead they are. In practice it rolls — built-in wheels and a pull handle mean you tow it, not hoist it. The 50.7-pound DELTA has no wheels: lighter, but you carry every pound. Which is easier comes down to whether your path has stairs or a smooth floor.
Warranty Value Comparison
The DELTA 2 Max gives you 5.3 years of warranty per $1,000 spent, vs the HomePower 3600 Plus's 2.9 years. That's 1.8× more coverage per dollar. An underrated factor if you're keeping this unit for years.
3,000 vs 6,000 Cycles, in Real Years
The Jackery's 6,000-cycle pack doubles the DELTA's 3,000 on paper. Cycled once a day that's roughly sixteen years against eight — both longer than most people keep the unit. The gap is real, but it's a tiebreaker for the buyer who cycles daily for a decade, not a headline for the one who runs it a few weekends a year.

EcoFlow DELTA 2 Max
Six months in, reviewers who'd put the DELTA 2 Max through real use reported no structural degradation — it felt as solid as day one, which is exactly what you want from a 3,000-cycle LFP packA3. Charging is genuinely fast, most of a full charge in under an hourA2. The recurring complaint is noise: the cooling fans climb audibly under heavy load or fast charging, enough that owners suggest giving it six inches of clearance and leaning on Quiet Charging mode when the racket matters more than the speedA1.
The consensus lands on a versatile, still-worth-buying unit with real expandability — bought with eyes open about the fanA4.

Who Should Buy Which
Buy the DELTA 2 Max if you…
- →The one-person household prepping for evening outages: 2,048Wh clears an 8-hour blackout and you can lift it into a closet yourself at 50.7 pounds.
- →Anyone whose heaviest single draw stays under 2,000Wh — a CPAP, a home office, a tailgate — and would rather bank the $322.
Buy the HomePower 3600 Plus if you…
- →The weekend camper or off-gridder who needs to clear 2,100Wh and still hold reserve — the Jackery does it at 69% of its bank.
- →The long-haul owner who'll genuinely cycle it for a decade-plus, where 6,000 cycles and eight-cent kilowatt-hours finally pay off.
- →Anyone building toward more solar: the 2,000W ceiling refills 3,584Wh in a single strong afternoon.
If neither fits
If your real target is running a home through a multi-day outage — the 4,685Wh daily load neither unit covers — stop comparing these two and look at a 5kWh-plus system or a pair of expansion batteries. Both of these leave you rationing by day two.
The Bottom Line
The HomePower 3600 Plus is the more capable box — 1,536Wh more, twice the cycles, twice the solar input — and if you'll consume that, it's the buy, and it's cheaper to own on a long enough clock. But capability you don't use is just weight and money. The DELTA 2 Max clears an evening blackout, a CPAP, and a workday at 26.5 pounds less and $322 cheaper, and over the warranty either unit will really see, it costs less per year.
So be honest about your biggest single draw. Under 2,000Wh, take the lighter EcoFlow and pocket the difference. Past 2,100Wh — or if you're truly buying for the next decade of daily cycling — the Jackery is worth every extra pound.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Jackery HomePower 3600 Plus worth $322 more than the EcoFlow DELTA 2 Max?
If you'll use the extra 1,536Wh — weekend camping, a bigger backup reserve, or years of daily cycling — yes. The Jackery holds more, lasts 6,000 cycles to the EcoFlow's 3,000, and refills at twice the solar rate. If your loads sit under 2,000Wh, the lighter DELTA does the same work for less.
Which one is actually cheaper to own?
The Jackery, at about eight cents per lifetime kilowatt-hour against the EcoFlow's twenty-one — but that only shows up if you cycle it deep into its 6,000-cycle life, roughly sixteen years of daily use. Over the five-year warranty both share, the DELTA is the cheaper unit to keep at $259 a year to the Jackery's $324.
How much heavier is the Jackery, and does it matter?
26.5 pounds heavier — 77.2 versus 50.7. It matters less than the number suggests because the Jackery rides on built-in wheels and a pull handle, while the 50.7-pound EcoFlow is a genuine one-person lift with no wheels. If your path has stairs, the EcoFlow is the easier haul; on a flat floor, the Jackery rolls.
Can either one run my whole house in a blackout?
Not for long. A full off-grid day draws around 4,685Wh, more than either unit holds. Both keep a fridge, lights, and devices going through an 8-hour evening — the DELTA at 94% of its usable bank, the Jackery at 54% — but neither is a whole-home, multi-day solution without expansion batteries.
