Spec deltas
Both of these run a CPAP overnight on about 320Wh, and one of them costs $4,100 less doing it. The Jackery HomePower 3600 Plus is $1,899; the DELTA Pro Ultra + 1 Battery is $5,999. Across the six loads we model, exactly one is a job the Jackery cannot finish.
That job is a van-life day: 4,685Wh of draw against 3,046Wh usable, once the same 85% usable factor is applied to both units. The Jackery stops about 65% of the way through, 1,639Wh short. The EcoFlow covers it and still holds 5,760Wh in reserve, and that gap is the honest argument for the money.
Everything else on this page is shaped by 293.6 lbs. The EcoFlow does not get carried, it gets sited, which is why the campsite and the tailgate go to the Jackery while 10,445Wh of usable capacity stays in the garage. Take the Jackery unless your day looks like that van, your outages run past a single night, or you are feeding more panels than a 1,000W input can take.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
Nine cents against twelve only pays out if you cycle the pack, and the scenarios say you will not: the EcoFlow finishes an eight-hour blackout at 16% used, with 8,800Wh untouched. Cents-per-kWh rewards the buyer who drains and refills, which on a 12,288Wh bank means a workshop or a van in daily service, not a winter evening with the fridge and a few lamps.
$5,999 buys 12,288Wh on the EcoFlow, which the data puts at $0.49 per Wh$1,899 buys 3,584Wh on the Jackery, or $0.53 per WhRated cycles: 4,000 on the EcoFlow, 6,000 on the Jackery
Why it mattersIf your worst week is two long evenings, you are not buying energy, you are buying a ceiling you visit twice a year. Buy the lower ceiling and keep the $4,100 that separates $5,999 from $1,899.
solar input
What it buys is the next battery. Capacity you add to the Jackery still arrives through the same 1,000W input, while the EcoFlow already refills a full 12,288Wh in about two hours at rated input, which is headroom its current bank does not need. That is the single place the solar spec earns its premium, and it only pays if the array and the bank are genuinely going to grow.
EcoFlow: 5,600W maximum solar input against a 12,288Wh bankJackery: 1,000W maximum solar input against a 3,584Wh bankBoth units accept their maker's expansion batteries
Why it mattersPlanning to add panels and batteries over the next few years? The EcoFlow's input ceiling is worth arguing about. Already own the panels you intend to own? Call the solar spec a tie and move on.
Jackery's failure is the mirror image: a login requirement during the exact event you bought the unit for. Neither app should move a decision this size, and the hardware ratings point the other way regardless, with the Jackery at 4.5 out of 5 on AmazonB4 against an EcoFlow evidence base whose thickest source is a complaint threadA0.
EcoFlow's app rates 4.6/5 on iOS from about 8,400 ratings and 4.2/5 on Android from about 17,000Jackery's rates 2.3-3.3/5, split across two apps, and wants a login even offlineOn this EcoFlow flagship there is no state-of-charge graph in the appA8, and one owner watched reported charge fall from 90% to 8% over a few daysA9
Why it mattersIf the app is your tiebreaker, you do not have one. Decide on weight, and on whether 3,046Wh finishes your day.
That inverts how the warranty table reads. The Jackery buys more coverage per dollar, $380 a year against $600, but coverage per dollar is a fact about price: if a fault turns up in year six, only one of these is still somebody else's problem. The 10-year term is the strongest non-capacity argument the EcoFlow has, and it is worth far more to the person who keeps hardware until it dies than to the person who upgrades every few years.
EcoFlow: 10 years of coverage, against a rated life of 11 years at daily cyclingJackery: up to 5 years, which is 3 years plus 2 more only if you register the unitJackery's rated life at daily cycling is 16.4 years
Why it mattersLong-haul keeper? The EcoFlow's decade of coverage is the line item to weigh against the price. Buying the Jackery? Register it the week it arrives, because two of those five years do not exist until you do.
The specific dimensions that decide these two units — everything else is a tie.
Portability & Form Factor
Selected because: One unit is 77.2 lbs and the other is 293.6 lbs, and that 216 lb gap settles two of the six scenarios before capacity is consulted.
weight
Two of the six rows are settled before capacity gets a word in. The Jackery takes Weekend Camping and Tailgate Party while the EcoFlow sits on 10,445Wh of usable capacity it cannot bring, because 293.6 lbs across several boxes is not something you load, it is something you site. That 216 lb difference is paid exactly once, on installation day, and then it stops mattering.
77.2 lbs is no featherweight either. It is a two-hands, bent-knees lift, and you want a second person for stairs. The difference is that you can still change your mind about where it lives.
Your Life, Your Pick
Selected because: Six loads, and only one of them, a 4,685Wh van-life day, is a job the Jackery physically cannot finish.
The scoreboard reads three rows to two with one shared, and it flatters the EcoFlow badly. It takes the 8-Hour Blackout at 16% used and the Remote Workday at 9%, which is not capability, it is surplus: the Jackery finishes both, with 1,401Wh and 2,136Wh left over. Only Van Life Daily separates them on what the hardware can do at all, and there it separates them decisively, 4,685Wh of demand against 3,046Wh usable.
Read the rows for shape rather than score. Every row the EcoFlow wins is a row where it never moves, and every row it loses is one where something had to. If no day of yours draws more than 3,046Wh, the expensive unit is winning arguments you will never have.
Lifetime Value
Selected because: $1,899 against $5,999 buys 3,584Wh against 12,288Wh, and the cheaper unit still lands lower per lifetime kWh, 9 cents against 12.
cost / lifetime kWh
The cheaper unit is also the cheaper one to own, which does not always happen. 6,000 rated cycles on a 3,584Wh pack is 21,504 kWh of lifetime energy for $1,899, or 9 cents a kWh; the EcoFlow's 4,000 cycles on 12,288Wh come to 49,152 kWh for $5,999, or 12 cents. Per warranty year it is $380 against $600.
Both figures assume you drain and refill the pack, and that is the part worth pausing on. On a 3,584Wh unit it happens: a household that runs it down over a long evening and tops it up next day is genuinely working through those 6,000 cycles. On a 12,288Wh bank bought for eight-hour outages, three quarters of the pack never moves and the 12-cent figure stays theoretical.
What the Specs Don't Tell You
Selected because: Five cards fire here, and three of them (UPS class, warranty term, absolute surge ceiling) go to the EcoFlow, which is the honest counterweight to our pick.
rated cycles
Three of the five cards here argue against our own pick, which is the fairest way to read this pair. The EcoFlow holds the higher absolute surge ceiling at 10,800W, the better-rated UPS class, and double the warranty term. The Jackery holds weight and cycle life. None of those is a tiebreaker alone, but the UPS and warranty cards are where a reader who needs those specific things should stop and reconsider the price.
The surge card is the one most often misread. A ratio tells you how far an inverter runs below its own rating; a ceiling tells you what a compressor can ask for at switch-on. The Jackery wins the ratio and the EcoFlow wins the number a motor cares about.
Growth Path
Selected because: Both take expansion batteries; the difference is that the EcoFlow's 5,600W solar input can feed a growing bank while the Jackery's 1,000W is the door everything has to come through.
solar input
Both units take expansion batteries, so the growth question is not whether you can add capacity, it is how fast you can put energy back into what you added. The Jackery's 1,000W input is a doorway you cannot widen. The EcoFlow's 5,600W refills its entire 12,288Wh in roughly two hours at rated input, which is headroom it does not need yet.
That only counts if growth is a plan rather than a maybe. Buying 12,288Wh and 5,600W of input against a future you have not costed is how people end up with 10,445Wh of usable capacity and a 1,645Wh evening to spend it on.

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
The Jackery takes this one by being able to attend. 2,100Wh of camp load against 3,046Wh usable leaves 946Wh, which is real but not generous: a second morning of coffee and phone charging puts you near the floor, so bring a panel if the weekend runs long. The EcoFlow has 10,445Wh usable for this scenario and no way to deliver it, because 293.6 lbs goes where you put it and stays there.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
DELTA Pro Ultra + 1 Battery
The EcoFlow's win here is about the second night, not the first. Both cover a 1,645Wh evening; it ends at 16% used with 8,800Wh banked, the Jackery at 54% with 1,401Wh. What narrows the gap is refilling, since 1,645Wh back through the Jackery's 1,000W input is under two hours of decent sun, so a run of single-evening outages never really tests it. A multi-day event does, and that is when the EcoFlow's 5.3 remaining nights stop being a spec-sheet number.

SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Neither unit will run short, so the capacity column has nothing to say. 320Wh across the night is 11% of the Jackery and 3% of the EcoFlow, and both finish the week on one charge if you let them. What decides your night is which unit can be beside the bed rather than parked in the garage, and one of these weighs 77.2 lbs while the other weighs 293.6 lbs.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
DELTA Pro Ultra + 1 Battery
The EcoFlow takes this row on slack rather than capability. A 910Wh day leaves it at 9% used with 9,535Wh untouched, but the Jackery finishes the same day at 30% and still holds 2,136Wh, which is two more days like it. Unless your workday includes a space heater or a table saw, both units are overqualified here and the margin is bragging rights.

Tailgate Party
Game day power for the crew
HomePower 3600 Plus
The most impressive number on this page is useless in a parking lot. The EcoFlow's 10,800W surge ceiling will start almost anything, and this scenario peaks at 400W, which both units take without noticing. So it comes down to what you can get from the car to the folding table, and 670Wh of draw against 3,046Wh usable means the Jackery does the job with 2,376Wh to spare.

Van Life Daily
A full day of mobile living — the ultimate endurance test
DELTA Pro Ultra + 1 Battery
This is the one row where the cheaper unit stops rather than strains. 4,685Wh of daily draw against 3,046Wh usable leaves the Jackery 1,639Wh short, about 65% of the day covered, and no amount of careful load juggling closes a gap that size. The EcoFlow covers it with 5,760Wh spare, the clearest justification for its price anywhere on this page. Be clear about what winning this row involves, though: 293.6 lbs installed in a vehicle, not a unit you carry in at night.

Conclusion
September 13, 2026
Verdict: the Jackery HomePower 3600 Plus
Buy the HomePower 3600 Plus. At $1,899 against $5,999 it is $4,100 cheaper, it covers five of the six loads we model, and the one it misses (4,685Wh of van-life draw, where it lands 1,639Wh short) is a day most households never have. The DELTA Pro Ultra + 1 Battery is not overpriced for what it is: 12,288Wh works out to $0.49 per Wh against the Jackery's $0.53, and it takes 5,600W of solar against 1,000W. It is a 293.6 lb appliance that gets sited once, which is why it loses the campsite and the tailgate while holding 10,445Wh of usable capacity it cannot bring. Spend the extra $4,100 only if your daily draw genuinely empties 3,046Wh, your outages run past one night, or you are wiring a house rather than plugging things into a box.

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 Pro Ultra + 1 Battery rates 3.7/5 (25th percentile of 29 Whole-Home / Off-Grid-class units), and HomePower 3600 Plus rates 4.1/5 (47th 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.
The 216 lb Gap Is Paid Once
77.2 lbs is a two-hands, bent-knees lift that one determined person can manage and two people should handle on stairs. 293.6 lbs across several boxes is not a lift at all, it is a decision about where the unit lives, made once, in daylight, with help. None of that hurts after installation day. What it costs you is the ability to change your mind later, which is exactly what the campsite and tailgate rows are about.
A Ratio and a Ceiling Are Not the Same Claim
The Jackery's maximum surge, 7,200W, is precisely the EcoFlow's steady-state rating. That is the cleanest way to see which number is which: the Jackery keeps the wider percentage margin above its own 3,600W, while the EcoFlow can swallow a 10,800W spike. A compressor draws watts at switch-on rather than a multiple of somebody else's rating, so the ceiling is the figure to check against the biggest motor you own.
Rated 0ms Is a Class, Not a Stopwatch
Both units offer a UPS mode and both figures are classifications rather than measurements: EcoFlow's rated 0ms describes a no-break design on paper, Jackery's is a limit of 20ms it says it will not exceed. For a router, a TV or anything with its own battery, neither figure matters. Desktop PCs and some NAS boxes are the machines that sit near that 20ms line, so if unsaved work is what you are protecting, the stated class deserves attention, and nothing here is a lab result.
Two of Jackery's Five Years Are Conditional
Jackery's 5-year term is 3 years plus 2 more that exist only once the unit is registered, so the longer figure is an action item rather than a fact about the box. Register it the week it arrives. The EcoFlow's 10 years is the longer term and the strongest argument for its price that has nothing to do with capacity, and it lands close to the 11 years of daily cycling its cell rating implies, so coverage and cells expire at roughly the same time.
Battery Lifespan in Real Years
The HomePower 3600 Plus is rated for 6,000 cycles vs 4,000. In real life: at daily use, that's 16.4 vs 11 years. At weekend use (twice a week), it's 58 vs 38 years. One caution reading years across different sizes: a cycle is 3,584Wh on the HomePower 3600 Plus and 12,288Wh on the DELTA Pro Ultra + 1 Battery, so count lifetime energy — roughly 21,504 kWh against 49,152 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.

Analyst note
The HomePower 3600 Plus wins on both sticker price and long-term value. At $0.09/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner. One caution on the lifespan row: the HomePower 3600 Plus takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the DELTA Pro Ultra + 1 Battery still delivers more over its shorter horizon (49,152 vs 21,504 kWh). Years measure wear, not usefulness.
Brand trust
EcoFlow
Ecosystem
The deepest catalogue in portable power, 12 to 15 models across DELTA Pro, DELTA 3 and RIVER 3, plus panels and smart home panels. The DELTA Pro Ultra platform sits at the top of it as a flagship route into whole-home backup rather than a feature of the wider line.
Support
US phone, email and chat, with genuinely polarized outcomes: prepaid replacement labels and quick resolutions for some, long waits and refurbished units against new-unit claims for others. Buying through Costco or Amazon adds a return desk as a backstop, which is worth more than it sounds on a 293.6 lb purchase.
Community
The largest community in the category, around 31,000 members on Reddit plus an official forum and active Facebook groups. On a configuration with this little published field data, that is where the answers actually live.
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
Fast charging, the widest ecosystem and the quickest innovation cadence among the majors. The app is also comfortably the best rated of the two here.
Worth knowing
Two things to file away. EcoFlow tested subscription paywalls for advanced app features in early 2025 and paused the plan after backlash, and it offers no parts or service once the warranty has run out. That second one sits oddly beside a 10-year term on an appliance you intend to keep.
Jackery
Ecosystem
Twelve to fifteen models or more across Explorer portables and HomePower home backup, with the SolarSaga panel line and some genuinely unusual form factors alongside them.
Support
The weak point, and the recurring complaints are specific: slow or scripted replies, strict receipt requirements on warranty claims, and refurbished replacements for clearly defective units. Keep the invoice, register the unit, and buy from a retailer with a returns counter.
Community
The smallest Reddit presence of the major brands at roughly 2,000 members, though brand recognition means YouTube coverage is thorough. Fewer people to ask, more videos to watch.
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
The widest retail distribution in the category, Costco, Home Depot, Best Buy and Amazon, which is itself a support strategy: a shelf you can carry the unit back to beats a ticket queue.
Worth knowing
The app is the weaker of the two by a wide margin, 2.3 to 3.3 out of 5, split confusingly across two apps and wanting a login even offline, which is a strange requirement during a blackout. A couple of older Jackery models still ship NMC cells with shorter rated lives; this one is not among them, at 6,000 rated cycles.
Analyst note
Neither brand's support is a reason to choose it, so buy whichever unit you pick from a retailer that takes returns. EcoFlow wins the app, the ecosystem and the community by a distance, and on a unit with this little published field data the community counts for more than usual. Jackery wins the thing you can use in a hurry: shelves in four national chains and a receipt you can walk back through the door.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA Pro Ultra + 1 Battery
Field data on this exact configuration is thin, and the thickest source is one DIY Solar Forum thread from February 2024A0. What is in it is specific and unflattering. One owner found the unit interfering with common radio frequencies including 146.520MHz even with the inverter idle, the emission clearing the moment the unit was switched offA6, and EcoFlow support's suggestion was a faraday cageA7. The same thread records no state-of-charge graph in the appA8, reported charge sliding from 90% down to 8% across a few days of overnight use and rechargingA9, and a superficial web user guide standing in for a real manualA5. His own summary was that he was meh on the unit and unlikely to expand it or integrate it into the houseA4.
Take the fan-noise material with a hand on the brakes. Those entries come from a blog discussing the DELTA Pro Ultra alongside EG4 competitor units, and our researcher could not confirm which unit two of them describeA0A2A3. One commenter's complaint that the fans always run is aimed at the EcoFlowA1; the detailed fan-hysteresis testing probably is notA3. Nobody in this ledger has lived with the plus-one-battery configuration long enough to report on it, and there is no cold-weather or UPS-switchover experience here at allA0.
“When the fans are not on, the inverter emits zero noise...even when I put my ear against the case.”

Jackery HomePower 3600 Plus
The Jackery's evidence has the opposite shape: plenty of it, and most of it review coverage rather than long-term ownershipB0. It holds 4.5 out of 5 on Amazon, with ease of use, quiet operation and reliable performance the recurring praiseB4; the 6,000-cycle LiFePO4 pack is described as EV-grade and good for well over a decade of serviceB1; and the roughly 77 lb body is consistently called manageable for its class thanks to built-in wheels and a pull handleB2.
The single most useful entry is one owner's three-day regional blackout, where a fridge, a microwave, string lights, fans and a CPAP ran for two straight days on one chargeB3. That is one report rather than a pattern, and it is worth holding next to our own arithmetic: 3,046Wh usable covers a 1,645Wh evening comfortably and a 4,685Wh day not at all. Notice also what you are comparing, a complaint thread on one side against review-site praise on the other, which is a difference in what got written down and not necessarily in the hardwareA0B0.
“EV-grade LiFePO4 battery rated for 6,000 cycles, giving well over a decade of service life.”

- Support interactions were unhelpful or dismissive when owners raised specific technical issues (manual gaps, RFI, missing SoC graph) [DELTA Pro Ultra + 1 Battery · 3 entries]
- Fan behavior/noise is a recurring point of owner scrutiny, though direct DPU-specific noise data is thin and partly inferred from sibling EG4 units [DELTA Pro Ultra + 1 Battery · 3 entries]
- Light weight (with wheels), a 6,000-cycle EV-grade battery, quiet reliable operation, and strong owner ratings are the standout praise. [HomePower 3600 Plus · 3 entries]

“At 6.3kW of load, the fan turned on... The fans turned off when I reached about 4.5kW. This is probably the expected hysteresis behavior.”

Who Should Buy Which
Buy the DELTA Pro Ultra + 1 Battery if you…
- →You are backing up a house rather than a room. 7,200W continuous with a 10,800W surge ceiling is service-panel territory, and 12,288Wh covers a 4,685Wh day twice over.
- →Your normal day genuinely draws more than 3,046Wh. That is the one row where the Jackery stops working rather than just working harder.
- →You are building toward more panels and more batteries and want the 5,600W input ceiling already in place before you start buying them.
- →You keep hardware for a decade and want coverage that runs the whole way: 10 years, against the 11 years of daily cycling the cell rating implies.
Buy the HomePower 3600 Plus if you…
- →Your worst night is the one we model as an eight-hour outage, 1,645Wh of fridge, lights, router and phones. That is 54% of the Jackery, and a morning of sun through the 1,000W input puts it back.
- →The unit has to come with you sometimes: the campsite, the tailgate, a parent's house during the storm. 77.2 lbs moves, 293.6 lbs does not.
- →You are powering a CPAP, roughly 320Wh a night, which leaves 2,726Wh spare. Buying 12,288Wh for that is renting a warehouse for a shoebox.
- →You want the lower cost per lifetime kWh, 9 cents against 12, and you will actually cycle the pack rather than dip into it twice a winter.
If neither fits
If your list is phones, laptops, a router and a CPAP, both of these are far too much box: a night of CPAP is 320Wh, and the cheaper unit here still holds 3,584Wh. Look at the 1kWh class, where $1,899 is not the price of admission, and spend the difference on a panel. And if you run a ham shack or any other sensitive RF gear, read the interference entry in the field notes before you commit to either oneA6A7, then treat RF behaviour as a spec you ask about rather than hope for on any inverter this size.
The Bottom Line
Take the HomePower 3600 Plus. $1,899 against $5,999 is the kind of gap that needs a reason, and across six modelled loads there is exactly one: a 4,685Wh van-life day that leaves the Jackery 1,639Wh short. Everywhere else the EcoFlow wins with capacity the scenario never asked for, 16% used in a blackout and 9% in a workday, and it loses outright the two rows where the box had to move.
The DELTA Pro Ultra + 1 Battery is the right answer to a different question. If you are putting 293.6 lbs somewhere permanent, feeding it 5,600W of panels and drawing thousands of watt-hours a day, it is honestly priced at $0.49 per Wh and it carries the longer warranty. If you are here because the power goes out a few times each winter and you would like the fridge and the CPAP to keep running, you already own too much unit. Buy the Jackery, register it, and put the difference into panels.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DELTA Pro Ultra + 1 Battery worth more than three times the price of the HomePower 3600 Plus?
Only if your daily draw actually empties the Jackery. $5,999 against $1,899 buys 12,288Wh against 3,584Wh and 7,200W against 3,600W, which is real hardware rather than a markup: the EcoFlow is the cheaper unit per watt-hour bought, $0.49 against $0.53. But of the six loads we model, the Jackery finishes five, and it is the cheaper unit per lifetime kWh at 9 cents against 12.
How long will the HomePower 3600 Plus keep my house going in a blackout?
About one full evening of essentials with room to spare, and not two. Our eight-hour outage profile draws 1,645Wh, which is 54% of the 3,046Wh the unit can usefully deliver, leaving 1,401Wh for the next morning. It runs loads rather than a service panel: 3,600W continuous with a 7,200W surge ceiling handles a fridge, lights, a router and a microwave, one at a time on the hungry ones.
Which one is better for a CPAP?
Both are, and the cheaper one by default. A CPAP is roughly 40W, about 320Wh across a night, which is 11% of the Jackery and 3% of the EcoFlow, so capacity is a formality either way. The question that matters is which unit can sit beside the bed instead of in the garage, and at 77.2 lbs against 293.6 lbs that is the Jackery.
Do I have to register my Jackery to get the 5-year warranty?
Yes. The 5-year figure is 3 years as standard plus 2 more once the unit is registered with Jackery, so the last two years are yours only if you do the paperwork, ideally in the first week. The EcoFlow is listed at 10 years, the longer term either way, and terms that long often carry their own conditions such as registration or buying direct, so check the wording on whichever you buy.
Can I add batteries to the Jackery later instead of buying the bigger unit?
Yes, it takes Jackery expansion batteries, but adding capacity does not widen the door that energy comes in through. Every extra watt-hour still charges through the same 1,000W solar input, while the EcoFlow refills its full 12,288Wh in about two hours at its rated 5,600W. If the plan is a bank that keeps growing, the input ceiling is the part of the EcoFlow's price you are actually buying.
