EcoFlow DELTA 3 Classic vs Jackery HomePower 3600 Plus
This is a stamina question, not a power question: the Classic starts every load on this page and finishes two of the six profiles, against the HomePower's five.

Spec deltas
The DELTA 3 Classic starts everything the HomePower 3600 Plus starts. It just doesn't finish. One box runs 1,800W with 3,600W of surge, the other 3,600W with 7,200W, the same doubling on both, and nothing in the six load profiles here asks for more than 400W of startup draw. The Classic clears all of it, then stops 775Wh short of the 1,645Wh an eight-hour blackout needs.
So the HomePower takes this, and the reason is the 3,584Wh it starts with rather than anything clever it does. It covers five of the six profiles with room left over; the Classic covers two, and both of those are light. Where it flips is the evening-sized list. A CPAP night is 320Wh, and spending $1,899 to move 320Wh out of 3,046Wh usable is a strange way to buy a battery.
The price gap is $1,400, and the part worth slowing down for is that the expensive unit is the cheap energy. Six thousand cycles on a 3,584Wh pack is 21,504 kWh across its rated life against the Classic's 3,072 kWh, seven times as much, for nothing like seven times the money. That only turns into money you saved if you cycle it, which is the honest catch on the pick.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Its two passes draw the real envelope: 320Wh for a CPAP night leaves 550Wh of the 870Wh usable untouched, and a 670Wh tailgate leaves 200Wh. Call it an evening and roughly 700Wh of genuine use. Every profile here that runs longer than one evening goes to the HomePower, which is the same thing that review said about the window AC with a smaller vocabulary.
DELTA 3 Classic: 1,800W output, 3,600W surge; HomePower 3600 Plus: 3,600W output, 7,200W surgehighest startup draw in any scenario here is 400W, and the Classic starts every one of them8-Hour Blackout needs 1,645Wh: the Classic is 775Wh short, about 53% covered; Remote Workday needs 910Wh and it misses by 40Whone review notes the 1,800W inverter starts a small window AC fine while the runtime stays shortA10
Why it mattersIf your list is a CPAP, phones, a laptop and lamps until bedtime, buy the Classic and keep the difference. If a fridge is on the list overnight, the Classic isn't in this comparison.
rated cycles
The catch is collection. Nobody is around for year 58, so that rate is a real advantage for a household cycling a 3.6kWh pack most weeks and pure arithmetic for someone who takes it out six times a summer. Weekend-only buyers should treat the per-kWh line as a tiebreak and not a reason, which is exactly the buyer for whom the cheaper box is also the cheaper box.
3,000 cycles of 1,024Wh is 3,072 kWh of rated lifetime energy; 6,000 cycles of 3,584Wh is 21,504 kWhcost per lifetime kilowatt-hour: 15 cents on the Classic, 9 cents on the HomePowerat weekend use the rated life runs 28.8 years for the Classic and 57.7 for the HomePower
Why it mattersOnly count the lifetime energy advantage if you can name the weekly load that spends it. Otherwise buy for the night you actually need covered.
solar input
In an outage you don't refill once, you refill every day, and the input cap sets the daily budget. Twice the input is twice the energy back per good solar day, so the HomePower's lead grows on day three instead of shrinking. The Classic's 500W ceiling means its small pack comes with a small solar allowance to match.
DELTA 3 Classic caps solar input at 500W into a 1,024Wh packHomePower 3600 Plus takes 1,000W into 3,584Whmore than one review outlet calls the 500W ceiling low for a 2026 releaseA5A9
Why it mattersIf you're buying for grid-down days rather than weekends, read the input cap as the survival spec and capacity as the consequence.
The fix isn't a bigger battery, it's the charger. Under an hour from empty to full on wall power, plus an automatic pre-storm top-up, means the Classic only ever needs a forecast to be ready. Forecast outages are its case. The unannounced kind is where 3,584Wh sitting there wins by default, having needed no plan at all.

Why it mattersStorm-season buyers can live with the small pack and a habit. If your outages are surprises, buy the capacity instead of the routine.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Six load profiles, and the pass/fail line falls between these two units: the Classic finishes two, the HomePower five, and neither finishes the 4,685Wh van-life day.
Two rows go to the Classic as passes, and both are light: 320Wh for a CPAP night, 670Wh for a tailgate. Everything longer breaks the same way. Weekend camping wants 2,100Wh against 870Wh usable, about 41% of the trip. The eight-hour blackout, which is what most people are actually here for, gets a bit over half.
The row worth staring at is the remote workday, because it's the only one the Classic loses on a rounding error. 910Wh needed, 870Wh usable, a 40Wh miss, and the nameplate 1,024Wh clears the day outright: the flat 15% conversion allowance is what tips it under. If your day looks like that one, the Classic is a coin flip you win by unplugging one thing. If your day is longer than that one, it isn't close.
Lifetime Value
Selected because: The price gap inverts here, at 15 cents per lifetime kilowatt-hour on the Classic against 9 cents on the HomePower.
cost / lifetime kWh
Fifteen cents per lifetime kilowatt-hour against nine. Read that once and the price gap stops being the headline, because the box that costs more is the one handing back energy at the lower rate, and it gets there by having 21,504 rated kilowatt-hours to divide the purchase into.
Collection is the honest problem. At weekend use the Classic's rated life runs 28.8 years and the HomePower's 57.7, and nobody collects year 58, so the rate rewards a household that cycles a 3.6kWh pack most weeks and means almost nothing to someone using it six times a summer. Work out which of those you are before you let a per-kilowatt-hour figure talk you up a tier.
Portability & Form Factor
Selected because: 26.7 lbs against 77.2 is the Classic's one clear win, and the only argument that overrules the capacity one.
weight
26.7 lbs is one hand and a passenger seat. 77.2 lbs is 50.5 lbs more of the same object (77.2 minus 26.7), which at that end of the scale is the difference between carrying and rolling, and the HomePower rolls: built-in wheels and a pull handle come on itB2, so across a garage floor it behaves like heavy luggage. The weight bill arrives where wheels don't help. Basement stairs, a tailgate lip, a campsite that isn't beside the car.
Weight also isn't the whole trailer answer. The HomePower carries a 30A RV outlet and the Classic's six AC sockets don't include one, so a shore cord plugs straight into one of these two and adapts into the other. Anyone whose plan starts with a shore cord has already finished deciding.
Growth Path
Selected because: One unit is sealed at 1,024Wh and the other starts at 3,584Wh and takes expansion batteries, which decides whether a sizing mistake is fixable later.
solar input
Buy the HomePower for its base, not its expansion. It does take Jackery expansion batteries, a card the sealed Classic can't play, but that's the third reason to own it rather than the first. The first is that 3,584Wh already covers the blackout and the camping weekend; expansion is for the buyer who'd outgrow that as well.
The Classic's ceiling is the box it arrives in. 1,024Wh, fixed, so a sizing mistake gets corrected by a second purchase instead of an accessory. That isn't a flaw at its price, it's a condition of sale: size the Classic for the load you can name today, not the one you suspect is coming.
Brand Trust
Selected because: The cheaper unit comes from the brand with the better app and the far bigger community, which is worth knowing before you spend more with the other one.
The uncomfortable part of recommending the HomePower is the column beside it. EcoFlow's app rates 4.6 on iOS against Jackery's 2.3 to 3.3 across stores, EcoFlow's community is the largest in the space while r/Jackery is the smallest at roughly 2,000 members, and Jackery's support record is the weaker of the two on response speed and on how strictly it asks for a receipt at warranty time. Jackery also ships multiple apps and wants a login even offline.
None of that outvotes 3,584Wh, but two things follow from it. Buy the HomePower somewhere with its own return window, which is easy given Jackery's distribution runs through Costco, Home Depot, Best Buy and Amazon, so a bad unit is a return rather than a warranty case. And if living with the app is part of what you're buying, that's the Classic's column, not the Jackery'sA6.

HomePower 3600 Plus
The DELTA 3 Classic doesn't finish — 870Wh usable against the 2,100Wh this needs leaves it 1,230Wh short, about 41% of the scenario covered. The HomePower 3600 Plus covers it with 946Wh to spare.

8-Hour Blackout
Keep the essentials running through a night without power
HomePower 3600 Plus
Eight hours is where the Classic's evening ends early. 1,645Wh needed against 870Wh usable, so it covers a bit over half and gives back the hours after bedtime, which are the ones you bought it for. The HomePower finishes with 1,401Wh still in the pack, enough to do a lighter version of the same night again tomorrow.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Both cover this several times over: 320Wh against 870Wh usable on the Classic and 3,046Wh on the HomePower. So a CPAP-only purchase isn't decided in the capacity column at all. It's decided by the fact that one of these sits on a nightstand at 26.7 lbs and the other needs the floor at 77.2. If that's the whole job, buy the small one.

HomePower 3600 Plus
The DELTA 3 Classic comes up just short — it needs 910Wh and has 870Wh usable, a 40Wh gap (its nameplate 1,024Wh actually clears this — the flat 15% conversion allowance is what tips it under). Trim that much — one small appliance's worth across the day — and it finishes. The HomePower 3600 Plus covers it outright with 2,136Wh to spare.

HomePower 3600 Plus
Both handle game day; the HomePower 3600 Plus keeps more in reserve (22% used vs 77%). Tailgating is a light load, though, so the number you'll feel is weight: 26.7 lbs for the DELTA 3 Classic against 77.2 lbs for the HomePower 3600 Plus, from the trunk to the setup spot.

Conclusion
September 19, 2026
Verdict: the HomePower 3600 Plus, on Power Score margin
Take the HomePower 3600 Plus unless your load list ends with the evening. Both units start everything on this page, so the decision is duration, and 3,046Wh usable finishes the eight-hour blackout with 1,401Wh spare and the camping weekend with 946Wh spare while the Classic's 870Wh comes up 775Wh and 1,230Wh short of those same two jobs. The lifetime arithmetic points the same way, 21,504 kWh of rated energy against 3,072 kWh, so the more expensive box is also the cheaper energy. It isn't a clean sweep, because the reverse case is real and common: a CPAP-and-devices buyer pays $1,400 more to move 320Wh, carries 77.2 lbs instead of 26.7, and gets nothing back for either.

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 Classic rates 4.1/5 (46th percentile of 27 Everyday-class units), and HomePower 3600 Plus rates 4.0/5 (42nd percentile of 20 Home Backup-class units).

HomePower 3600 Plus: 77.2 lbs, But It Rolls
77.2 lbs is a two-hands, bent-knees lift if you have to carry it, and mostly you don't: built-in wheels and a pull handle come on this unit, which turns flat ground into dragging heavy luggage. The weight bill arrives where wheels are no help. Basement stairs, a tailgate lip, a campsite that isn't next to the car. That's where the Classic's 26.7 lbs is the number to compare against, not in the garage.
DELTA 3 Classic: Fixed Capacity
The DELTA 3 Classic is sealed at 1,024Wh — fine if that covers you, but it's the ceiling. By contrast the HomePower 3600 Plus can add expansion batteries, though the first thing it has over the DELTA 3 Classic is its own 3,584Wh base — expansion is the step after that, for the buyer who would outgrow 3,584Wh as well.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The HomePower 3600 Plus's figure is a maximum rather than a guarantee — it depends on registering the unit with Jackery, which is what extends the base term to the full period. Worth saying because the per-dollar framing can suggest otherwise: the DELTA 3 Classic works out at 10 years of cover per $1,000 spent against the HomePower 3600 Plus's 2.6, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The HomePower 3600 Plus is rated for 6,000 cycles vs 3,000. In real life: at daily use, that's 16.4 vs 8.2 years. At weekend use (twice a week), it's 58 vs 29 years. One caution reading years across different sizes: a cycle is 3,584Wh on the HomePower 3600 Plus and 1,024Wh on the DELTA 3 Classic, so count lifetime energy — roughly 21,504 kWh against 3,072 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.
Full record above — the Test Desk pick is the HomePower 3600 Plus.

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
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
A couple of older models still ship NMC chemistry with a shorter rated lifespan, so check the cycle rating on the specific unit — though most of the current line has moved to LFP. Generally perceived as overpriced for the specs offered compared to newer competitors. App experience is significantly behind rivals.
Analyst note
Straight trade here: the cheaper unit comes from the stronger brand file. EcoFlow's app rates 4.6 on iOS against Jackery's 2.3 to 3.3, and EcoFlow's community is the largest in the space while r/Jackery is the smallest at roughly 2,000 members, so there's more crowd to troubleshoot with at 2 a.m. Jackery's counterweight is where you can buy it, with Costco, Home Depot, Best Buy and Amazon all stocking the line. Use that: a retailer with its own return window is the best protection either of these brands offers, because both support operations read better on paper than in the queue.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 Classic
The Classic's field record is early rather than thin by accident. It launched in March 2026, so what exists is hands-on reviewing rather than long-term ownership, and its retailer review page mixes in comments that appear to describe a DELTA 2 instead, which we left out of the recordA0A15.
What did get measured is useful. Empty to full from a standard wall outlet in just under 55 minutesA1, roughly 17W of idle drawA2, and quieter under test than the price had reviewers expectingA2A3. The handle is solid and centeredA11, the AC and USB ports sit on the front with charging inputs moved to the backA4, and both the app and Storm Guard's automatic top-up come up as genuine strengthsA6A12. The recurring complaint is the 500W solar ceiling, called low for a 2026 release by more than one outletA5A9, and one review pairs that with the runtime point directly: the 1,800W inverter starts a small window AC fine, and then doesn't hold it for longA10.
“In our tests, the DELTA 3 Classic charged from empty to full plugged into a standard wall outlet in just shy of 55 minutes.”

Jackery HomePower 3600 Plus
The HomePower's record is smaller in volume and better in kind, because it contains somebody's actual blackout: one owner ran a fridge, a microwave, string lights, fans and a CPAP machine for two straight days on a single charge during a three-day regional outageB3. That single entry does more for the 3,584Wh number than any line in the spec table.
Around it, coverage settles on three things: the 6,000-cycle EV-grade LiFePO4 packB1, a 4.5-out-of-5 Amazon rating with repeated praise for quiet and uncomplicated operationB4, and the detail our spec record misses, which is that at about 77 lbs the unit ships with built-in wheels and a pull handle and reads as light for a 3.6kWh classB0B2.
“EV-grade LiFePO4 battery rated for 6,000 cycles, giving well over a decade of service life.”

Who Should Buy Which
Buy the DELTA 3 Classic if you…
- →Your whole list is a CPAP, phones, a laptop and a couple of lamps for one night. That's 320Wh against 870Wh usable, and the 550Wh left over is margin you'll never touch.
- →You carry it. Tailgates, picnic tables, a friend's porch, the footwell of a sedan: 26.7 lbs with a centered handleA11 goes places 77.2 lbs doesn't get invited to.
- →Your outages come with a forecast. Under 55 minutes from empty to full on wall powerA1 and an automatic top-up before the weather landsA12 mean the small pack is a full pack on the night that counts.
- →You need the sockets more than the hours. Six AC outlets and two 100W USB-C ports is a lot of simultaneous small stuff for a 26.7 lb box.
Buy the HomePower 3600 Plus if you…
- →You want the fridge still running at breakfast. 3,046Wh usable covers the 1,645Wh eight-hour blackout with 1,401Wh left, which is the difference between riding out an outage and rationing one.
- →You camp for a weekend, not an evening. 2,100Wh fits with 946Wh spare, where the Classic finishes the same trip 1,230Wh short.
- →You own a travel trailer. The 30A RV outlet is on the Jackery and not the EcoFlow, and for you that one socket outranks every other spec on this page.
- →You'll cycle it often enough to actually collect the lower lifetime energy cost: near-daily backup duty, a home office that rides out brownouts, a setup you expect to grow past 3,584Wh with expansion batteries.
If neither fits
Anyone with a 4,685Wh day, which is what full-time van life looks like here. Neither unit finishes it: the HomePower gets about two-thirds of the way and the Classic under a fifth, and the answer is a larger station or a wired house bank, not the better of these two. Same verdict for whole-home backup through a transfer switch. That's a different category, and buying the biggest portable in the room is how people end up with an expensive extension cord.
The Bottom Line
Take the HomePower 3600 Plus. Nothing on this page needs more startup punch than the Classic already has, and the Classic still loses five profiles to two, which is the whole matchup: a fridge overnight and a weekend in a tent are stamina problems, and 3,584Wh is what a stamina problem wants. The lifetime numbers happen to agree, seven times the rated energy for nothing like seven times the price, which is the rare case of the expensive box also being the cheap one per kilowatt-hour.
The Classic keeps one clean win and it deserves naming, because plenty of people reading this should take it. If your night is a CPAP and a phone charger, you're buying 870Wh of usable energy for $499 and lifting 26.7 lbs instead of 77.2, and the HomePower's extra 2,560Wh (3,584 minus 1,024) is an expensive way to not need it. Everyone else: the bigger one, and don't let the price gap talk you into a box that quits at 2 a.m.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DELTA 3 Classic enough for a power outage?
For a few hours, yes. For a full evening with a fridge in it, no. Our eight-hour blackout profile needs 1,645Wh and the Classic has 870Wh usable after the flat 15% conversion allowance, so it covers a bit over half and stops 775Wh short. Think of it as a lights-and-devices outage unit rather than a keep-the-kitchen-running one.
Why does the HomePower 3600 Plus cost less per kilowatt-hour when it costs more to buy?
Because the purchase divides into far more energy. 6,000 cycles of 3,584Wh is 21,504 kWh across the rated life, against 3,000 cycles of 1,024Wh for 3,072 kWh. Seven times the energy, and the price gap is nowhere near seven times. That only becomes money you saved if you actually cycle the pack, so a six-weekends-a-year buyer shouldn't pay a tier up for it.
Could I just buy two DELTA 3 Classics instead of one HomePower 3600 Plus?
Two Classics cost less than one HomePower and still land 1,536Wh short of it, since two 1,024Wh packs is 2,048Wh against 3,584Wh. The bigger problem is that they don't gang: each is its own 1,800W inverter, so you'd be splitting circuits across two boxes rather than running one 3,600W load. Two small stations solve a port-count problem, not a capacity problem.
Is the DELTA 3 Classic's 500W solar limit a problem?
It's the most-flagged thing about the unit, called low for a 2026 release by more than one outlet. Day to day it's fine, because 500W refills 1,024Wh in about two hours of strong sun. It bites on a multi-day outage, where the HomePower's 1,000W input banks roughly twice as much energy back per good solar day.
Which one is better for a CPAP?
Both cover it easily, which is why the cheap one wins. A CPAP night runs about 320Wh, 37% of the Classic's usable 870Wh and 11% of the HomePower's 3,046Wh, and neither struggles to start it. Buy the HomePower for CPAP duty only if the same unit is also meant to be the outage plan for the rest of the house.
