Spec deltas
Twenty-seven pounds against 77.2, and that's the whole decision. The scenario sweep, the cost per kilowatt-hour, the cycle rating: all of it follows from whether this box gets carried or parked.
The HomePower 3600 Plus takes five of the six load profiles here and the sixth is a loss for both, which sounds like a rout and isn't quite one. The DELTA 3 isn't losing because it's a worse machine. It's losing because 1,024Wh is a different job than 3,584Wh, and four of these six profiles ask for more than 1,024Wh holds. On the two that don't, a CPAP overnight and a tailgate afternoon, it finishes with room to spare.
Which unit is better isn't the question. Which purchase you're making is. If it lives next to the breaker panel, buy the HomePower and accept that you'll move it once. If it lives in the back of a car, buy the DELTA 3, keep the $1,150 ($1,699 minus $549), and go in knowing a blackout is not what you bought it for.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
solar input
Its escape hatch is daylight. At nameplate input the DELTA 3 puts its entire 1,024Wh back in about two hours (1,024 divided by 500), which is genuinely fast and completely unavailable at 2 a.m., which is when the grid picks to go down. The HomePower refills 3,584Wh in about that same two hours (3,584 divided by 2,000), so it returns three and a half times the energy on the same clock, and it started the night with enough that it didn't need the trick.
8-Hour Blackout needs 1,645Wh: 189% of the DELTA 3's usable energy, 54% of the HomePower'sRemote Workday needs 910Wh: 105% for the DELTA 3, 30% for the HomePowerDELTA 3 solar input tops out at 500W; HomePower at 2,000W
Why it mattersIf the grid is why you're shopping, the DELTA 3 is out at any price, and adding a solar panel doesn't rescue it.
rated cycles
Double the cycle rating turns that seven-cent gap ($0.54 minus $0.47) into a structural one: 21,504 kWh of lifetime energy against 3,072, seven times the throughput, which is how the HomePower lands at 8 cents per lifetime kilowatt-hour and the DELTA 3 at 18. The $1,150 you keep by buying small buys you less energy per dollar, not cheaper energy.
Price: $549 (DELTA 3) vs $1,699 (HomePower)Cost per watt-hour: $0.54 vs $0.47Cycle rating: 3,000 vs 6,000Total lifetime throughput: 3,072 kWh vs 21,504 kWh
Why it mattersAnyone reaching for the DELTA 3 to save money should reach for it because of the 27 pounds instead, because on money it loses.
weight
Wheels solve pavement, not basement stairs, tailgates, or a boat ramp, and the mobility praise the HomePower earns is explicitly graded on the 3.6kWh-class curveB2 rather than against a 27-pound box. Set beside something you pick up one-handed and put on a picnic table, 77.2 lbs isn't portable. It's a two-person load or a dolly.
27 lbs (DELTA 3) vs 77.2 lbs (HomePower)Reviewers describe the HomePower as about 77 lbs with built-in wheels and a pull handle, light for a 3.6kWh-class unitB2Tailgate Party needs 670Wh: 77% of the DELTA 3's usable energy, and it clears itCPAP Overnight needs 320Wh: 37% for the DELTA 3
Why it mattersIf this thing leaves the house more than a few times a year, the DELTA 3's smaller ceiling stops being a flaw and becomes the reason to buy it.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: The DELTA 3 clears two of the six load profiles and runs dry on the other four, which is the fastest way to find out whether 1,024Wh is your size.
Five wins and a shutout isn't the story. Van Life Daily asks for 4,685Wh and neither unit gets there, 154% of what the HomePower can deliver and 538% of the DELTA 3, so that sixth row is a message about the whole category rather than about either machine. Full-time van power is an installed 12V house bank with roof solar, not a box on the floor you keep refilling.
The rows that matter are the near misses. A remote workday asks 105% of what the DELTA 3 can deliver; a camping weekend asks 241%, which means two refills before Sunday, assuming you brought panels and the sky cooperates. One of those is a unit you'd resent by Saturday afternoon. The other is a unit you'd resent by 4 p.m. on a Tuesday.
Portability & Form Factor
Selected because: 27 lbs against 77.2 lbs is the one axis where the DELTA 3 isn't merely competitive, and it's the axis most likely to decide this for you.
weight
Twenty-seven pounds is a one-hand lift out of a trunk and a walk to a picnic table. Seventy-seven and change is bent knees, both hands, and a hard no on basement stairs, which is exactly why the HomePower ships with wheels and a pull handleB2. Wheels are wonderful on a driveway and useless on the three steps up to it.
This cuts both ways, and it's why the sweep above doesn't settle the page. If the unit's permanent address is a utility room beside the panel, its weight is a one-time problem you solve on delivery day. If it rides in a car most weekends, you'll feel every one of those 77.2 pounds, and 1,024Wh you can actually carry beats 3,584Wh you left at home.
Lifetime Value
Selected because: The $549 unit costs more per watt-hour than the $1,699 one ($0.54 against $0.47), worth understanding before the sticker does your deciding.
cost / lifetime kWh
Cheap and inexpensive part company here. The DELTA 3 asks $549 and the HomePower $1,699, and the HomePower still costs less per watt-hour of the energy you're buying, then doubles the cycle rating on top of it. Eight cents per lifetime kilowatt-hour against eighteen isn't a rounding difference, it's the same energy at a different price.
The honest counterweight is the calendar. There's a real argument that year twelve of a power station is somebody else's problem, since the cells will be old and something better will cost less by then. Judged over the five years of warranty both units carry, you're spending $110 a year on the DELTA 3 against $340 on the HomePower. The lifetime math is true. Don't let it talk you into capacity you'll never cycle.
Brand Trust
Selected because: Both companies' direct support draws complaints, so the practical question is which retailer you buy through rather than which logo is on the box.
Neither support desk is a reason to pick a side. EcoFlow's US line draws polarized reports, hassle-free prepaid-label replacements from some buyers and long waits or refurbished units against new claims from others. Jackery's is criticized more consistently: scripted agents, slow replies, strict receipt requirements, refurbished replacements for units that failed outright. Both brands' own owners land on the same advice, which is to buy through Costco or Amazon so someone else's return policy covers you.
Where they genuinely differ is everything around the box. EcoFlow has the deepest ecosystem in portable power, the largest owner community in the category at roughly 31,000 on Reddit against Jackery's 2,000, and an app rated 4.6 on iOS where Jackery's sits between 2.3 and 3.3 across two confusingly similar apps that want a login even when you're standing next to the unit. Jackery's answer is distribution: Costco, Home Depot, Best Buy, Amazon. If the app matters to you, that's a point for EcoFlow. If a physical returns counter matters more, that's a point for Jackery.

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
HomePower 3600 Plus
Two nights want 2,100Wh. The HomePower spends 69% of its usable energy on the trip and drives home with 31% still in the tank. The DELTA 3 needs 241% of what it holds, so it's two refills before Sunday, which means panels, sun, and a lot of watching a charge screen instead of a fire. The catch is that somebody still has to get 77.2 lbs to the site.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
HomePower 3600 Plus
The HomePower spends 54% of its usable energy on this and goes back to sleep. The DELTA 3 needs 189% of what it holds, so this isn't a matter of managing loads carefully. It's out before morning. This row is where the price gap lives.

SCN-03 · 8 hours · needs 320Wh
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 many times over and the capacity margin is a formality. They're also within a decibel or two of each other, so the one thing that would separate them doesn't. Buy whichever is cheaper or easier to carry.

Remote Workday

HomePower 3600 Plus
One hundred and five percent. That's the DELTA 3's share of the 910Wh a remote workday asks for, and missing by five percent is somehow worse than missing by half, because you'll believe it's going to make it right up until it doesn't. The HomePower spends 30% on the same day and you forget it's in the room.

Tailgate Party
Game day power for the crew
HomePower 3600 Plus
The HomePower takes this one and uses 22% of its usable energy doing it. But 670Wh is 77% of the DELTA 3's, which means it also finishes the afternoon, and it's the one you carried from the car in a single hand. Headroom wins the scoreboard. Twenty-seven pounds wins the parking lot.

Neither unit
Neither unit, and not by a little. A full day of van living asks 4,685Wh, which is 154% of what the HomePower can deliver and 538% of the DELTA 3. If this is your life, the answer is an installed 12V house bank with roof solar, and it isn't on this page.

Conclusion
August 1, 2026
Verdict: the HomePower 3600 Plus, on Power Score margin
Take the HomePower 3600 Plus if the unit is going to live in one place. Five of the six load profiles here land above what the DELTA 3 can actually deliver, including an ordinary remote workday at 105%, and the HomePower is the cheaper unit by the measure that counts: 47 cents per watt-hour against 54, before either one is switched on. The DELTA 3 isn't a bad buy, it's a different one. At 27 lbs against 77.2 it's the only one of the two you lift with one hand, and if what you actually need is a CPAP through the night (37% of its usable energy) or a tailgate afternoon (77%), it does the job and leaves $1,150 in your pocket. Buy the big one for the house. Buy the small one for the trip.

Runtime model
Runtime = (rated capacity × 0.85 inverter efficiency) ÷ device wattage. Solar recharge estimates assume panels deliver 70% of rated output. Cold weather, battery age, and stacked loads reduce real-world results.
Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
See the full weight table and data sourcing on our methodology page →Class ranking (the star rating)
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 rates 4.3/5 (61st percentile of 24 Everyday-class units), and HomePower 3600 Plus rates 4.4/5 (67th 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.
77.2 lbs is light for 3,584Wh and still heavy
Both things are true. For a 3,584Wh unit, 77.2 lbs is a genuinely good number. It is also a two-person lift over a tailgate and a bad idea on basement stairs, so pick its address before it arrives, because you'll want to move it exactly once. The DELTA 3 is 27 lbs and goes wherever you're going.
10ms against 20ms, and our pick loses it
The DELTA 3 hands over in 10ms and the HomePower in 20ms, one of the few spec lines the cheaper unit wins outright. Both are measured in milliseconds rather than seconds, so treat it as a tiebreak rather than a reason. If your desk gear is genuinely switchover-sensitive, the DELTA 3 is the safer of the two by a factor of two.
Warranty Value Comparison
The DELTA 3 gives you 9.1 years of warranty per $1,000 spent, vs the HomePower 3600 Plus's 3.1 years. That's 2.9× more coverage per dollar. An underrated factor if you're keeping this unit for years.
3,000 cycles against 6,000
Double the cycles is double the calendar: cycled daily, the DELTA 3's rating works out to 8.2 years and the HomePower's to 16.4. Whether that second decade is worth paying for today is a fair question, and the fair answer is that most people replace a power station long before its cells give up. What the cycle rating really buys here is the lifetime cost gap, not a guarantee you'll still want it in year sixteen.

The DELTA 3 is cheaper to buy, but the HomePower 3600 Plus is cheaper to own. At $0.08/kWh over its lifetime vs $0.18/kWh, the HomePower 3600 Plus's higher cycle life and capacity make each dollar go further over the years.
Brand trust
EcoFlow
Ecosystem
The deepest lineup in portable power, 12 to 15 models from RIVER 3 up to DELTA Pro, plus panels and smart home panels. If you expect to add to this later, EcoFlow gives you the most places to go.
Support
US phone, email, and chat, with polarized results. Some buyers get a prepaid label and a fast replacement; others wait and receive a refurbished unit against a new claim. Buying through Costco or Amazon puts a real return policy between you and that lottery.
Community
The largest owner community in the category, around 31,000 on Reddit plus active Facebook groups and an official forum. When something odd happens at 11 p.m., somebody has already posted about it.
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
Fast charging, and an app people actually use: 4.6 on iOS across roughly 8,400 ratings, 4.2 on Android across about 17,000.
Worth knowing
EcoFlow recalled the DELTA Max 2000 in October 2025 over an overheating and fire risk tied to six incidents. That's a different model from this one, but it's worth knowing about a brand shipping this many SKUs. The company also floated subscription tiers for advanced app features in early 2025 and backed off after owners objected, and it offers no parts or service once you're out of warranty.
Jackery
Ecosystem
Explorer for portable, HomePower for home backup, 12 to 15 models plus the SolarSaga panel line and the occasional genuinely odd swing like a solar gazebo. Narrower than EcoFlow's, and coherent.
Support
The weak spot, and consistently so: scripted agents, slow replies, strict receipt requirements on warranty claims, and refurbished replacements for units that failed outright. Buy it at Costco and let the returns counter be your warranty department.
Community
The smallest of the major brands at roughly 2,000 on Reddit. YouTube coverage is solid because the brand is famous, which is not the same thing as having people to ask.
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
Distribution. Costco, Home Depot, Best Buy, and Amazon all stock it, so you can see one, return one, and buy one the ordinary way. On a $1,699 purchase that's worth more than it sounds.
Worth knowing
The app is the weakest of the major brands at 2.3 to 3.3 stars, split across two confusingly similar apps that demand a login even when you're standing next to the unit. A couple of older Jackery models still ship NMC cells with shorter rated lives, so the cycle rating is worth checking on any Jackery you buy. This one isn't among them, at 6,000 cycles.
Analyst note
EcoFlow gives you the better software, the bigger ecosystem, and the people to ask. Jackery gives you a store you can drive to. Neither support desk is a selling point, so buy whichever unit you're buying from a retailer whose return policy you trust, and treat the manufacturer warranty as the backup plan rather than the plan.

Both expand, but the HomePower 3600 Plus's higher solar ceiling (2,000W vs 500W) gives it the stronger off-grid growth path — more panels can feed a bigger bank as it grows.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3
Field data on the standard DELTA 3 is thin, and what exists comes from reviewers rather than long-term ownersA1A2. Testing does back the quiet claim on this specific model: under 200W the fans often stay off entirely, and between 500W and 800W they're barely audible from three feet awayA1. That's the behavior that matters when the unit shares a bedroom.
The 10ms UPS handoff was measured on a DELTA 3 sibling that shares the same switchover spec rather than on this unit, so treat it as likely rather than confirmedA2. Where it was measured, routers didn't reset and fridges didn't skip a compressor cycleA2.
“At low loads (under 200W) the fans often stay completely off, making the Delta 3 effectively silent; under moderate load (500–800W) the fans are barely audible from three feet away.”

The most useful single report: during a three-day regional blackout, one owner ran a fridge, a microwave, string lights, fans, and a CPAP machine for two straight days on a single chargeB3. That's the load profile people buy a 3.6kWh box for, and it's the one the DELTA 3 has no path to.

Who Should Buy Which
Buy the DELTA 3 if you…
- →You're buying this for a tent, a truck bed, or a folding table at a soccer field, and it goes back in the trunk on Sunday. 27 lbs is the spec you'll use most.
- →Your real load is a CPAP overnight (37% of the DELTA 3's usable energy) or a tailgate afternoon (77%). Both fit with room left, and you keep $1,150.
- →You want a bedside UPS for a router, a laptop, and a CPAP, and a 10ms switchover plus fans that stay off under 200WA1 matter more to you than capacity.
- →You're starting a system rather than finishing one. It takes EcoFlow expansion batteries, so 1,024Wh is a starting point rather than a hard ceiling.
Buy the HomePower 3600 Plus if you…
- →The box has a permanent address beside the breaker panel and gets moved once, on delivery day.
- →You're sizing for an outage rather than an outing. The 8-hour blackout profile runs 54% of this unit and 189% of the DELTA 3's.
- →You cycle it hard and often, and the 6,000-cycle pack is rated for double the DELTA 3's 3,000.
- →You're going off-grid with real panels. A 2,000W solar ceiling against 500W is what makes daily refills at this scale possible.
If neither fits
Full-time van and RV dwellers should close both tabs. The daily van-life profile here needs 4,685Wh, which is 154% of what the HomePower can deliver and 538% of the DELTA 3, so the honest answer is an installed 12V house bank with roof solar and a dedicated inverter rather than a plug-in box you keep recharging. Same if you want the whole house on a transfer switch: that's an electrician and a permanent battery, not either of these.
The Bottom Line
Take the HomePower 3600 Plus if the box parks and the DELTA 3 if it travels. That isn't a hedge, it's the actual fault line: five of the six load profiles here sit above what 1,024Wh can deliver, including a plain remote workday at 105%, and the unit that covers them also costs less per watt-hour and less per lifetime kilowatt-hour than the unit that doesn't.
The DELTA 3's case is one number and it's a good one. Twenty-seven pounds goes where 77.2 doesn't, and a CPAP night or a tailgate never comes near its ceiling. If that's your life, buy it, pocket the difference, and don't feel talked down to. If you're shopping because the lights went out in February, buy the big one and get it into the utility room before you need it.

Not for the kind people plan for. The 8-hour blackout profile needs 1,645Wh, which is 189% of what the DELTA 3 can actually deliver from 1,024Wh, so it's finished well before the lights come back. It does cover the CPAP-overnight profile at 37% of its usable energy. It does not cover a household evening.
Is the Jackery HomePower 3600 Plus worth $1,150 more?
If it's going to sit still, yes, and it's the cheaper unit by the measure that counts: 47 cents per watt-hour against the DELTA 3's 54, before you get to the 6,000-cycle pack. If it's going to travel, no. You'd be paying $1,699 for 3,584Wh you can't carry when the thing you needed was the 27-pound box.
Can I just buy three DELTA 3s instead of one HomePower?
You'd spend $1,647 (three times $549) to save $52, and end up with three separate 1,024Wh boxes instead of one 3,584Wh one. They don't pool: three units can't gang together to start the 3,600W load the HomePower runs on its own, because each one tops out at 1,800W. You'd also be walking three sets of cords around the house during an outage. If you want more than 1,024Wh from EcoFlow, the expansion battery is the path.
Which one is quieter for a CPAP?
Both carry the same 30 dBA rating, so the spec sheet calls it a tie. The tiebreak is behavior at low load: on the DELTA 3, testing found the fans often stay off entirely under 200W, and a CPAP night is 37% of its usable energy, so it never works hard. The HomePower runs the same night at 11% and owners praise it as quiet. If the unit sleeps two feet from your head, either is fine, and the DELTA 3 costs $1,150 less to put there.
