Head-to-head test
EcoFlow DELTA 3 Max Plus vs Jackery HomePower 3600 Plus
This comes down to capacity you'll actually use: below what a 2,048Wh unit can finish, the lighter, cheaper EcoFlow does the same job; above it, only the Jackery's 3,584Wh gets you there — and it's the cheaper energy while doing it.

Spec deltas
The Jackery HomePower 3600 Plus stores 3,584Wh to the EcoFlow DELTA 3 Max Plus's 2,048Wh, runs 6,000 charge cycles against the EcoFlow's 4,000, and — despite a $1,619 sticker against $999 — costs less per watt-hour over its life, $0.08 against $0.12.
What the extra $620 doesn't buy is a unit you can pick up. The Jackery is 77.2 lb, and it ships with wheels and a pull handle because at that weight you roll it rather than carry itB2. The EcoFlow is 50.7 lb, a one-hand lift off a tailgate, and it switches to battery in 10ms against the Jackery's 20ms — the margin a desktop or CPAP notices and a lamp never will.
So the decision is really about capacity you'll consume. A two-night weekend off-grid runs about 2,100Wh, which drains the EcoFlow past empty and leaves the Jackery with roughly a third of its tank. If your loads stay under that, buy the lighter, cheaper EcoFlow and don't look back. If they don't, the Jackery is the only one of the two that does the job.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
The bigger tank is also the cheaper energy: you're not paying a premium per watt-hour for the Jackery's capacity, you're paying less for it, while gaining the headroom that turns 'barely finished' into 'half a tank left for a second night.'
The EcoFlow needs 121% of its 2,048Wh for a 2,100Wh weekend and ends an 8-hour blackout at 94% drawn; the Jackery covers the weekend at 69% and the blackout at 54%The Jackery's lifetime energy costs $0.08 per kWh against the EcoFlow's $0.12
Why it mattersAnyone whose real loads cross roughly 1,600Wh should take the Jackery — the EcoFlow's capacity is a low ceiling for home backup, and undercutting it on price per kWh removes the usual reason to settle for less.
The Jackery's lifetime economics are real but deferred: they depend on cycling it daily for 16 years, so within any realistic ownership window the EcoFlow is the cheaper unit and the per-kWh figure is a promise, not a discount you feel.
The Jackery costs $1,619 against the EcoFlow's $999, a $620 gapOver the 5-year warranty the EcoFlow works out to $200 a year against the Jackery's $324; the Jackery's $0.08 lifetime-kWh edge assumes all 6,000 cycles, about 16 years of daily use
Why it mattersIf you're not cycling daily for over a decade, judge on the sticker and the warranty-year cost, where the EcoFlow leads — don't buy the lifetime-kWh number as if you'll cash it.
weight
For a stationary install that never moves, the weight is a one-time problem and the Jackery's capacity wins going away; for a unit that travels between camp, garage, and driveway, the 26 fewer pounds and the faster 10ms transfer both tilt the EcoFlow's way.

Why it mattersDecide by whether this unit lives in one spot or travels — that single question settles the matchup faster than any spec on the page.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Capacity is the decision axis: the EcoFlow misses the exact home-backup jobs the Jackery finishes.
The scenarios sort cleanly by capacity. A weekend off-grid (about 2,100Wh) defeats the EcoFlow at 121% of its tank and the Jackery clears it at 69%; an 8-hour multi-appliance blackout leaves the EcoFlow at 94% drawn — essentially empty — while the Jackery ends it at 54%, ready for a second evening.
The lighter loads erase the gap. A CPAP overnight (about 320Wh), a remote workday, a tailgate afternoon — both units clear these with most of the tank untouched, so if that's your ceiling the extra capacity is capacity you paid for and won't use. And van life defeats both: a full day runs about 4,685Wh, past even the Jackery's 154% mark, which is a reason to buy bigger, not a reason to pick between these two.
Lifetime Value
Selected because: The Jackery is cheaper per lifetime kWh but pricier per warranty-year — the honest split that decides for most horizons.
cost / lifetime kWh
The Jackery is the cheaper energy and the pricier box at the same time. Twice-plus the capacity for $620 more drops it to $0.08 per lifetime kWh against the EcoFlow's $0.12 — you're buying watt-hours at a discount, provided you buy a lot of them over a long time.
The warranty-year cost tells the story a buyer actually lives: $200 a year for the EcoFlow against $324 for the Jackery, over an identical 5-year term. The Jackery earns its price back per watt-hour across 6,000 cycles and 16 years of daily use — a horizon most owners retire the unit long before reaching. Within any realistic window, the EcoFlow is the cheaper unit to own.
Portability & Form Factor
Selected because: 26.5 lb and wheels-vs-carry is the EcoFlow's clearest structural win.
weight
Twenty-six and a half pounds separate these two, and it's the difference between a lift and a production. The EcoFlow, at 50.7 lb, you pick up and carry; the Jackery, at 77.2, comes with wheels and a pull handle because Jackery knew you wouldn'tB2. On flat ground that's a non-issue. On basement stairs it's the whole issue.
This only matters if the unit moves. A backup box that lives in one corner of the garage is weighed once, on the way in, and never again — and there the Jackery's capacity is worth its heft. But for anyone hauling it to a campsite or between house and car, the EcoFlow's 26 fewer pounds is a daily dividend the spec sheet undersells.
Brand Trust
Selected because: Cross-brand: app, support, and innovation cadence diverge sharply and are worth surfacing.
The two brands diverge most where you'll touch them daily: the software. EcoFlow runs the stronger app and the faster innovation cadence in the category; Jackery's app is the weakest of the major brands, with multiple confusing versions and a mandatory login even offline. Neither fact changes whether the unit runs in a blackout, but one is a daily annoyance and the other isn't.
Support is a wash you should route around. Both brands draw real criticism — slow responses, refurbished replacements, strict receipt rules — so the practical move with either is to buy through Costco or Amazon and let the retailer's return policy be your backstop. Worth knowing on the EcoFlow side: the October 2025 DELTA Max 2000 recall over overheating risk is a mark on the record, even on a different model.

Weekend Camping
Two nights off-grid with essential comfort
HomePower 3600 Plus
A two-night off-grid weekend runs about 2,100Wh. The EcoFlow can't quite finish it; the Jackery covers it and keeps roughly a third of the tank in reserve. If camping is why you're buying, that's the whole argument in one line.

8-Hour Blackout
Keep the essentials running through a night without power
HomePower 3600 Plus
Both survive the night, but there's survive and there's survive with reserve. The EcoFlow ends the blackout essentially empty; the Jackery ends it with half a tank, ready for a second evening if the grid stays down.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A tie that isn't close to either unit's limit — a CPAP sips a fraction of the tank all night. Break it on the switchover instead: the EcoFlow's 10ms transfer is the quieter, safer pick two feet from your head.

Remote Workday
Full work day off-grid without power anxiety
HomePower 3600 Plus
The HomePower 3600 Plus gives you a comfortable buffer at 30%. Enough to work late, join extra video calls, or charge a second device without worry. The DELTA 3 Max Plus at 52% works but leaves less room for the unexpected. For daily remote work, that peace of mind matters.

Tailgate Party
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.

Conclusion
July 16, 2026
Verdict: the HomePower 3600 Plus, on Power Score margin
For a genuine home-backup buyer, the Jackery HomePower 3600 Plus is the more capable unit and, counterintuitively, the cheaper one per watt-hour: 3,584Wh against 2,048Wh, 6,000 cycles against 4,000, and $0.08 per lifetime kWh against $0.12. The EcoFlow's 2,048Wh runs out on a weekend off-grid (it needs 121% of its tank) and ends an 8-hour multi-appliance blackout essentially empty, while the Jackery finishes both with half a tank left. The catch the Jackery makes you pay for is weight and price: 77.2 lb against 50.7, and $620 more the day you buy. If your real loads stay under roughly 1,600Wh, the EcoFlow does the same work for $620 less, 26 fewer pounds, and a faster 10ms switchover — so match the box to the loads and the winner flips with them.

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 Max Plus rates 4.3/5 (58th percentile of 25 Large-class units), and HomePower 3600 Plus rates 4.3/5 (60th percentile of 16 Home Backup-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.
77 Pounds Is a Roll, Not a Carry
The Jackery ships with wheels and a pull handle for a reason: at 77.2 lb it's a two-person lift or a wheel-and-ramp job. The EcoFlow, at 50.7 lb, you pick up with one hand. If the unit lives in one spot, weight is a one-time problem; if it travels, it's the EcoFlow's clearest win.
10ms vs 20ms: Only Your Electronics Are Counting
Both switch over fast enough for a fridge or the lights. The EcoFlow's 10ms transfer, half the Jackery's 20ms, is the margin a desktop, NAS, or router can register as a power event. Backing up sensitive gear tilts to the EcoFlow; everything else calls it a wash.
Same 5 Years, Different Yearly Cost
Both carry a 5-year warranty. Over that term the EcoFlow works out to $200 a year against the Jackery's $324, purely from the lower sticker. The Jackery earns its price back per watt-hour over the long run, not over the warranty.
6,000 Cycles You Probably Won't Reach
The Jackery's 6,000-cycle rating beats the EcoFlow's 4,000 — about 16 years of daily cycling against 11. Both figures outlast the warranty many times over, so unless you're cycling daily for well over a decade, this gap is real on paper and academic in your garage.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 Max Plus
Reviewers frame the Max Plus as the genuine step up on the DELTA 3 platform: 3,000W continuous with a 6,000W surge, a real jump over the plain Max's 2,400WA1. The standout in the field is how quietly it does it — testers report it barely registering above room noise even while charging at full power, the fans only spinning up briefly at shutdownA2.
It's also built to grow, with expansion from 2kWh up to 10kWh via Smart Extra Batteries that reviewers describe as polished and effortless, across five charging methodsA4. Long-term owner data is still thin on this newer unit, but the review consensus across output, quiet, and scalability is consistentA1A2A4.
“Bumps output to 3,000W continuous with a 6,000W surge — a significant upgrade over the DELTA 3 Max's 2,400W and 4,800W surge.”

Jackery HomePower 3600 Plus
The Jackery's headline in the field is longevity: an EV-grade LiFePO4 pack rated for 6,000 cycles, which reviewers put at well over a decade of serviceB1. One owner rode out a three-day regional blackout on a single charge, running a fridge, a microwave, string lights, fans, and a CPAP for two straight days before rechargingB3 — the multi-appliance endurance the capacity promises, confirmed in the wild.
It's also more manageable than 77 pounds sounds: built-in wheels and a pull handle make it genuinely mobile on flat ground, which reviewers call light for a 3.6kWh-class unitB2. Owner ratings run strong, with consistent praise for quiet, reliable operationB4. The catch stays the stairs — wheels don't help you carry it to a basement.

Who Should Buy Which
Buy the DELTA 3 Max Plus if you…
- →Your real loads stay under about 1,600Wh — a CPAP, a workday of electronics, a tailgate — and you'd rather keep the $620 and the 26 fewer pounds.
- →You move the unit: camp to car, garage to driveway. At 50.7 lb it's a one-person lift, and the 10ms switchover makes it the safer pick for a desktop or NAS you can't let reboot.
Buy the HomePower 3600 Plus if you…
- →You're buying real home backup — a weekend off-grid or a multi-appliance blackout — where 2,048Wh runs out and 3,584Wh finishes with reserve to spare.
- →You'll keep it a decade-plus and cycle it often: 6,000 cycles and $0.08 per lifetime kWh make it the cheaper energy if you actually reach that horizon.
If neither fits
If your real need is van life or whole-home for a multi-day outage — roughly 4,685Wh a day — both come up short; the Jackery alone still needs 154% of its tank. Look at a larger single unit or a two-battery setup instead of stretching either of these to a job neither is sized for.
The Bottom Line
Buy on capacity. If your real loads cross what a 2,048Wh unit can finish — a weekend off-grid, a multi-appliance blackout — the Jackery's 3,584Wh is the only one of the two that gets you there, and it's the cheaper energy per watt-hour while doing it. That it also runs 6,000 cycles is a tiebreaker you won't live long enough to cash.
If your loads stay light, none of that is worth $620 and 26 extra pounds. The EcoFlow is lighter, cheaper today, faster to switch over, and backed by the better app. Match the box to the loads and the winner picks itself.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Jackery HomePower 3600 Plus worth $620 more than the EcoFlow DELTA 3 Max Plus?
If you need the capacity, yes. Its 3,584Wh finishes a weekend off-grid or a multi-appliance blackout that the EcoFlow's 2,048Wh can't, and it costs less per lifetime watt-hour, $0.08 against $0.12. If your loads stay light, the EcoFlow does the same job for $620 less and 26 fewer pounds.
Which one is easier to move?
The EcoFlow, clearly. It's 50.7 lb, a one-person lift. The Jackery is 77.2 lb and ships with wheels and a pull handle because you roll it rather than carry it — fine on flat ground, a real problem on stairs.
Does the switchover speed difference actually matter?
Only for sensitive gear. The EcoFlow transfers to battery in 10ms, the Jackery in 20ms. A desktop, NAS, or router can register a 20ms gap as a power event; a fridge or a lamp never will. If you're backing up a computer you can't let reboot, the EcoFlow's faster transfer is the safer bet.
Which lasts longer?
The Jackery, on paper by a wide margin: 6,000 rated cycles against 4,000, about 16 years of daily cycling versus 11. Both outlast their 5-year warranty many times over, so this only decides the matchup if you truly cycle daily for well over a decade.
Is the Jackery's weaker app a dealbreaker?
Not for backup. The app matters for monitoring and settings, not for whether the unit runs during an outage — and in a blackout you want a box that works without the cloud anyway. If day-to-day app polish matters to you, EcoFlow's is the stronger one, but it shouldn't decide a home-backup purchase.
