Spec deltas
Only one of these two can finish a 4,685Wh day without running dry. The Jackery HomePower 3600 Plus would need 154% of the battery it actually has. The EcoFlow DELTA Pro Ultra finishes at 90% and stops there. That's Van Life Daily, the single scenario on this page heavy enough to separate two whole-home-class power stations that agree with each other almost everywhere else.
None of that headroom is free. The DELTA Pro Ultra lists at $3,999 against the HomePower's $1,619, a $2,380 gap for 2,560Wh more capacity and twice the continuous output, 7,200W against 3,600W. Yet over each unit's full cycle life, the two deliver identical total energy: 21,504 kWh either way. The extra money buys bigger, less frequent servings of the same total power, not more of it.
The HomePower answers back in three places that have nothing to do with price. Its cell is rated for 2,500 more charge cycles, its surge-to-continuous ratio (2.0x against 1.5x) is the better of the two, and at 77.2 lbs it's light enough for one person to wheel around. The DELTA Pro Ultra, at 181.8 lbs, is a two-person lift that stays wherever you first put it down.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
Every other scenario on this page, camping, blackouts, a CPAP, a tailgate, has both units covering the load with room left, which is what makes Van Life Daily the only real stress test here: it's the single load heavy enough to expose the capacity gap the spec sheet already promised.
Van Life Daily needs 4,685Wh; the DELTA Pro Ultra uses 90% of its capacity to cover it while the HomePower would need 154%Capacity: DELTA Pro Ultra 6,144Wh vs HomePower 3,584Wh, a 2,560Wh gap
Why it mattersIf your daily draw is anywhere near whole-home or full-time-RV scale, only the DELTA Pro Ultra actually qualifies. The HomePower runs out before the day does.
rated cycles
So the $2,380 premium on the DELTA Pro Ultra isn't buying more lifetime power. It's buying the same total energy delivered in fewer, bigger servings: $0.19 per lifetime kWh against the HomePower's $0.08.
Total lifetime energy: DELTA Pro Ultra 6,144Wh x 3,500 cycles = 21,504 kWh; HomePower 3,584Wh x 6,000 cycles = 21,504 kWh, identicalPrice: $3,999 vs $1,619, a $2,380 gap
Why it mattersAnyone shopping on cost per kWh over the life of ownership should default to the cheaper unit, since the extra money on the pricier one buys higher wattage per moment, not more total energy over time.
continuous output
For any appliance under about 3,600W continuous, that makes the smaller, cheaper unit proportionally the more prepared of the two for a hard compressor start, even though the bigger number lives on the DELTA Pro Ultra's spec sheet.
Surge ratio: DELTA Pro Ultra 10,800W surge over 7,200W continuous, 1.5x; HomePower 7,200W surge over 3,600W continuous, 2.0xA fridge or AC compressor can surge 2-3x its rated draw at startup
Why it mattersDon't shop the surge column by the biggest number alone. For loads inside the HomePower's range, its ratio is the one that should reassure you, not the DELTA Pro Ultra's.
Combined with its lower cost per lifetime kWh, the HomePower's battery chemistry is doing double duty: rated to last longer and cheaper to buy, the opposite of the pattern this category usually trains you to expect.
Cycle life: DELTA Pro Ultra rated 3,500 cycles vs HomePower rated 6,000, a 2,500-cycle gapCycled daily: 9.6 years for the DELTA Pro Ultra vs 16.4 years for the HomePower, a 6.8-year gap, before either settles to 80% capacity
Why it mattersSomeone buying on long-term durability, not peak capability, has a real, spec-backed reason to pick the cheaper unit here, not just a budget-driven one.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Van Life Daily is the only scenario that actually separates these two; the rest just confirm both are comfortable at lighter loads.
Five of six scenarios here are close to a formality. A CPAP overnight and a tailgate party both come back marked as a tie because neither battery notices the load. 320Wh and 670Wh don't stress a battery in the 3,584-6,144Wh range enough to name a winner. Weekend Camping, an 8-hour blackout, and a remote workday all go to the DELTA Pro Ultra on paper, but the HomePower finishes all three with real capacity left too.
Van Life Daily is the exception, and it's the whole point of this page. A 4,685Wh day is enough to separate them completely. The DELTA Pro Ultra finishes at 90% capacity used; the HomePower would need 154% of what it actually has. That's not a close scenario with a nominal winner attached. It's the one place these two units stop being interchangeable.
Lifetime Value
Selected because: Identical total lifetime kWh (21,504 both) makes the $2,380 price gap and cost-per-kWh split the cleanest value story on the page.
cost / lifetime kWh
Strip away the sticker prices and these two batteries deliver identical total lifetime energy: 21,504 kWh, whether it's the DELTA Pro Ultra's 6,144Wh over 3,500 cycles or the HomePower's 3,584Wh over 6,000. The $2,380 price gap isn't buying more total power over the unit's life. It's buying that same total power delivered in fewer, bigger installments.
That shows up directly in cost per lifetime kWh: $0.19 for the DELTA Pro Ultra against $0.08 for the HomePower. That's a real gap, not a rounding tie-break. Anyone optimizing purely for dollars per kWh over years of ownership has a straightforward answer here, before capacity even enters the conversation.
What the Specs Don't Tell You
Selected because: Four gotchas fire (weight, surgeRatio, ups, cycleLife) and split 2-2 by side, which undercuts a simple bigger-always-wins read.
rated cycles
Two specs that usually separate whole-home units don't, here: both idle at the same 30dB and both cap USB-C at 100W, so neither is a reason to pick a side. The four gotchas that do fire split evenly instead. Weight and UPS speed favor the DELTA Pro Ultra's case for higher-end use: at 181.8 lbs it's a two-person lift, 104.6 lbs heavier than the HomePower, but its 0ms switchover is a genuine step up from the HomePower's 20ms standby tier.
The HomePower answers with the other two. Its 7,200W surge is 2.0 times its own continuous rating, better than the DELTA Pro Ultra's 1.5 times, and its cell is rated for 6,000 cycles against 3,500, 2,500 more. Bigger and more expensive doesn't win every axis here, and these two cards are the proof.
Growth Path
Selected because: Solar ceiling gap (5,600W vs 2,000W) matters most to the exact daily/off-grid buyer Van Life Daily describes.
solar input
Both units expand rather than cap out, so neither buyer is locked into today's capacity forever. But the DELTA Pro Ultra's 5,600W solar ceiling is close to triple the HomePower's 2,000W, which matters far more to the off-grid, daily-cycling buyer this page is really about than it does to a weekend camper.
A bigger solar intake doesn't just mean a faster top-up on a sunny day. It means the DELTA Pro Ultra's larger bank is realistic to keep full without a wall outlet, while the HomePower's growth path leans more on plugging in than on panels alone.
Brand Trust
Selected because: Cross-brand pair with real texture: EcoFlow's recall vs Jackery's weak support/app, worth a plain-spoken section.
EcoFlow is the bigger, faster-moving ecosystem, with the deeper expansion lineup and the larger community, but it also carries a recent recall (the DELTA Max 2000, October 2025, over an overheating and fire risk) and a paywall experiment it had to walk back. Jackery has none of that baggage, but it also has the weaker support experience and the least-loved app of the major brands.
Neither issue is a reason to flip the verdict above. These two are being bought for what they physically do, not for app polish. But it's fair context, and buying either one from Costco or Amazon rather than direct adds a return safety net worth having regardless of brand.

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
DELTA Pro Ultra
Weekend Camping needs about 2,100Wh over two nights. The DELTA Pro Ultra covers it using 40% of its capacity; the HomePower needs 69% for the same weekend. Both make it through fine, but the EcoFlow does it with much more margin to spare, worth knowing if you tend to run a weekend long.

LOAD Phone Charger 15W×6h · LED Lights 40W×8h · Box Fan 75W×14h · CPAP Machine 40W×16h
SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
DELTA Pro Ultra
An 8-hour blackout pulls roughly 1,645Wh. That's 31% of the DELTA Pro Ultra's battery and 54% of the HomePower's. Both ride it out, but the HomePower is already past the halfway mark on an outage that might run longer than 8 hours.

LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h
SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP overnight is a rounding error for either battery: 320Wh is 6% of the DELTA Pro Ultra and 11% of the HomePower. Neither number is worth optimizing around. If this is your heaviest night, buy on price and portability, not capacity.
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
A remote workday, laptop, monitor, router, phone, runs about 910Wh. The DELTA Pro Ultra uses 17% of its battery for it; the HomePower uses 30%. Still comfortable for both, just a bigger bite out of the smaller tank.

SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
Either unit
Tailgate Party asks for about 670Wh: 13% of the DELTA Pro Ultra, 22% of the HomePower. Both shrug this off, so let weight decide instead. The HomePower is 104.6 lbs lighter, which matters more in a parking lot than either percentage does.

Van Life Daily
A full day of mobile living — the ultimate endurance test
DELTA Pro Ultra
Van Life Daily is the outlier. 4,685Wh a day pushes the DELTA Pro Ultra to 90% of capacity, tight, but it gets there. The HomePower would need 154% of what it has. It isn't close on this one. It runs out before the day does.

Conclusion
July 28, 2026
Verdict: the DELTA Pro Ultra, on Power Score margin
Take the DELTA Pro Ultra if your draw is anywhere near whole-home or daily-van-life scale. It's the only one of these two that clears Van Life Daily's 4,685Wh need (90% used, with room left, against the HomePower's 154%), it wins four of six scenarios outright while the HomePower never takes one alone, and it carries the higher power score, 8,600 against 5,714. That capability costs $2,380, and it isn't a clean sweep: the HomePower is 104.6 lbs lighter, rated for 2,500 more charge cycles, wins the surge-to-continuous ratio that predicts real motor starts (2.0x against 1.5x), and comes in at $0.08 per lifetime kWh against the DELTA Pro Ultra's $0.19. If your heaviest night looks like a CPAP or a tailgate, both of which leave either battery mostly untouched, buy the HomePower and keep the difference.

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 rates 4.9/5 (93rd percentile of 16 Home Backup-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.
The DELTA Pro Ultra Is a Two-Person Lift
At 181.8 lbs, the DELTA Pro Ultra needs two people and stays wherever you first set it down. The HomePower is 104.6 lbs lighter at 77.2 lbs, heavier than a large suitcase, but one person can still wheel it into place.
The HomePower Wins the Surge-Ratio Math
The DELTA Pro Ultra has the bigger surge ceiling in absolute terms, 10,800W against 7,200W. But measured against each unit's own continuous rating, the HomePower's surge is 2.0 times its 3,600W continuous output, while the DELTA Pro Ultra's is 1.5 times its 7,200W. The ratio that predicts whether a fridge or AC compressor actually starts favors the smaller unit.
True Zero-Millisecond UPS vs 20ms Standby
The DELTA Pro Ultra switches to battery in 0ms, true uninterruptible power; sensitive gear like NAS arrays and medical devices won't register the handoff. The HomePower's 20ms standby switchover is still fast enough for most electronics, but it's not the same tier.
6,000 Cycles vs 3,500: the Cheaper Unit Outlasts the Pricier One
The HomePower is rated for 6,000 charge cycles to 80% capacity; the DELTA Pro Ultra for 3,500, 2,500 fewer. Cycled daily, that's the difference between roughly 16.4 years and 9.6 years of rated life before either battery settles to 80% of its original capacity.

Brand trust
EcoFlow
Ecosystem
The widest lineup in the category, DELTA Pro, DELTA 3, and RIVER 3 series plus solar panels and smart home panels, with the DELTA Pro Ultra sitting at the top of it and expandable into a full home-backup bank.
Support
US-based phone, email, and chat support, though experiences split sharply, from fast prepaid-label replacements to long waits and refurbished units sent back for a fresh claim. Buying through Costco or Amazon adds a return safety net either way.
Community
The largest community in the category by a wide margin, with an active subreddit, several Facebook groups, and an official forum, useful when troubleshooting a home battery setup at 11 p.m.
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
The fastest charging in the category and the deepest expansion ecosystem, scaling into a large modular bank if the DELTA Pro Ultra alone stops being enough.
Worth knowing
EcoFlow recalled the DELTA Max 2000 in October 2025 over an overheating and fire risk, a different product line, but worth knowing before buying into the ecosystem. It also floated a paywall for advanced app features in early 2025 before backing off.
Jackery
Ecosystem
A smaller, more focused lineup, Explorer portables and the HomePower home-backup series, plus the SolarSaga panel line and some genuinely unusual form factors like a solar gazebo.
Support
Widely criticized: slow, scripted responses, strict receipt requirements for warranty claims, and refurbished units offered in place of replacements for clearly defective ones. Buying from Costco or Amazon is the strong recommendation here too.
Community
The smallest dedicated community of the major brands, though brand recognition keeps a solid YouTube presence going.
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 most recognized name in the category and the widest retail footprint, sold at Costco, Home Depot, Best Buy, and Amazon. The dependable, no-surprises choice, if not the most cutting-edge one.
Worth knowing
Jackery has been slower than rivals to move its full lineup to LFP chemistry, and its app is the weakest of the major brands', two logins, a confusing dual-app setup, and a mandatory sign-in even offline.
Analyst note
EcoFlow is the faster-moving, better-supported ecosystem with one real recall on its record. Jackery is the safer, blander brand name with the weaker support and app experience. Neither is a reason to flip the verdict above, the DELTA Pro Ultra wins on capacity and the HomePower wins on cost, but if brand support quality is the tiebreaker elsewhere, weight it in.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA Pro Ultra
Owners call the DELTA Pro Ultra an easy-to-set-up whole-home backup with strong solar input and solid app monitoring, and note its 7,200W inverter is enough to start a 3-ton central ACA4. Its LFP cells are rated for well over a decade of useA2, it charges unusually fast for its size, and its online UPS keeps sensitive electronics protected around the clock while staying quiet under everyday loadsA3.
The tradeoff for that scale is simple physics, not a complaint: at 181.8 lbs, it's a two-person lift once it's out of the box, and it stays wherever you first put it. Growing past one unit means adding EcoFlow's own expansion batteries to the same platform instead of starting overA1.

Who Should Buy Which
Buy the DELTA Pro Ultra if you…
- →Anyone whose daily draw looks like van life: a fridge, an induction cooktop, a laptop, and AC or heat off one battery, day after day. At 4,685Wh a day the DELTA Pro Ultra sits at a comfortable 90% of capacity; the HomePower would need 154% of what it has and simply can't finish the day.
- →Anyone who wants a true zero-millisecond UPS for a home office or medical equipment. The DELTA Pro Ultra's 0ms switchover is a different tier from the HomePower's 20ms standby, and it's the one upgrade here that isn't just about having more Wh.
Buy the HomePower 3600 Plus if you…
- →Anyone whose heaviest night is a CPAP, a tailgate, or an 8-hour outage. All three leave the HomePower with real capacity to spare, and $2,380 stays in your pocket.
- →Anyone optimizing for cost per kWh over the long haul. The HomePower amortizes to $0.08 per lifetime kWh against the DELTA Pro Ultra's $0.19, and its 6,000-cycle battery is rated to outlast the EcoFlow's 3,500-cycle cell by 2,500 cycles.
If neither fits
Skip both if your heaviest night looks like a CPAP overnight, which uses just 6% of the DELTA Pro Ultra and 11% of the HomePower. That's real headroom going unused on either unit, and a smaller, cheaper power station will cover the same night for a lot less money.
The Bottom Line
This comparison is a capacity-class question wearing a UPS-and-surge-ratio disguise. The DELTA Pro Ultra is the only one of these two that clears a true daily-driver load, 90% of a 4,685Wh day against the HomePower's 154%, and it backs that with the faster UPS and the bigger power score, 8,600 against 5,714.
The HomePower isn't the consolation prize, though: it's $2,380 cheaper, 104.6 lbs lighter, wins the surge-ratio math, and is rated to outlast the EcoFlow by 2,500 cycles. If your heaviest night is a CPAP or a tailgate, buy the HomePower and spend the savings on something more interesting than headroom you'll never use.

Is the EcoFlow DELTA Pro Ultra worth $2,380 more than the Jackery HomePower 3600 Plus?
Only if you need the extra capacity. The DELTA Pro Ultra carries 2,560Wh more (6,144Wh vs 3,584Wh) and twice the continuous output, 7,200W against 3,600W, which is the difference between finishing a 4,685Wh van-life day at 90% capacity and needing 154% of what the HomePower has. If your heaviest night looks like a CPAP or a tailgate, you're paying for headroom you'll never use.
Which one is cheaper to run over its lifetime?
The HomePower, and it's not close. Both units deliver about the same total lifetime energy, 21,504 kWh either way, but the DELTA Pro Ultra costs $0.19 per lifetime kWh against the HomePower's $0.08. That gap comes from the $2,380 lower price, not from any difference in how much total power you'll pull from either battery over its life.
Does the bigger surge number mean the DELTA Pro Ultra handles motor startups better?
Not proportionally. The DELTA Pro Ultra's 10,800W surge is larger in absolute terms, but it's only 1.5 times its own 7,200W continuous rating. The HomePower's 7,200W surge is 2.0 times its 3,600W continuous rating, the better ratio, and the ratio is what predicts whether a fridge or AC compressor actually starts.
How much longer does the Jackery's battery actually last?
Its cell is rated for 6,000 cycles against the DELTA Pro Ultra's 3,500, 2,500 more. Cycled daily, that pencils out to about 16.4 years before it settles to 80% capacity, versus roughly 9.6 years for the EcoFlow. Neither battery dies at that point. It just holds less than it did new.
Is either of these overkill for a CPAP or a weekend of camping?
Both, honestly. A CPAP overnight needs about 320Wh, 6% of the DELTA Pro Ultra and 11% of the HomePower, and a camping weekend needs about 2,100Wh, comfortably inside either battery. If that's your actual use case, buy on price and portability, not capacity you'll never touch.
