Spec deltas
Take the HomePower 3000. It costs $1,399 against the DELTA 2 Max's $1,049, and that $350 buys 1,024Wh more battery, 1,200W more continuous output, and 1,000 more charge cycles. Priced per watt-hour, the extra capacity works out around 24 cents. The DELTA 2 Max charges 46 cents for each of the watt-hours it already has.
That gap turns into a decision where people actually use these. A 2,100Wh camping weekend is more than the DELTA 2 Max's 2,048Wh nameplate before you subtract a single inverter loss, so it finishes the trip only if the trip gets shorter. The HomePower 3000 covers the same weekend with a fifth of its usable energy still in the tank.
The EcoFlow still has a case, and it isn't a sympathy case. It's 8.8 lbs lighter, it goes 0 to 80% at a wall outlet in about 50 minutesA2, and its app rates 4.6 on iOS where Jackery's sits between 2.3 and 3.3. If you're buying the box you carry rather than the battery you fill, that's a real argument for keeping the $350.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
That works out to 10 cents per lifetime kilowatt-hour on the HomePower 3000 and 15 on the DELTA 2 Max. Nothing on the EcoFlow's side of the table is worth paying half again as much on every kilowatt-hour the unit will ever produce: not the app, not the 8.8 lbs, not the expansion port.
DELTA 2 Max: $1,049 for 2,048Wh, rated 3,000 cyclesHomePower 3000: $1,399 for 3,072Wh, rated 4,000 cyclesRated lifetime energy: 6,144 kWh (2,048Wh x 3,000) against 12,288 kWh (3,072Wh x 4,000)
Why it mattersAnyone keeping the unit past a single season should pay the $350 and stop optimizing the sticker.
solar input
The obvious fix is to recharge mid-trip, and that's where the EcoFlow's real strength turns out to be in the wrong place. Its 50-minute 0-to-80%A2 happens at a wall outlet, which is the one thing a campsite doesn't have. On sun, a full DELTA 2 Max refill takes about two hours at its 1,000W ceiling (2,048Wh at 1,000W), and a full HomePower 3000 takes about the same at 1,400W (3,072Wh at 1,400W). The bigger battery is not the slower one to fill.
Weekend Camping draws 2,100Wh; the DELTA 2 Max is rated 2,048WhThat weekend consumes 121% of the DELTA 2 Max's usable energy and 80% of the HomePower 3000'sSolar input ceilings: 1,000W on the DELTA 2 Max, 1,400W on the HomePower 3000
Why it mattersIf your weekend looks like the 2,100Wh one modeled here, the DELTA 2 Max is a one-night unit and you should buy the Jackery.
continuous output
And expansion adds hours, not watts. However much battery hangs off the DELTA 2 Max, its inverter stays at 2,400W, so anything drawing between 2,400W and 3,600W runs on the HomePower 3000 and never runs on the EcoFlow at all. Buyers reach for expandability because they expect their needs to grow, and the needs that actually grow tend to be loads rather than hours.
DELTA 2 Max is expandable; HomePower 3000 is fixed at 3,072WhThe DELTA 2 Max's base capacity is 2,048Wh, which is 1,024Wh below the HomePower 3000's fixed ceilingContinuous output: 2,400W on the DELTA 2 Max with 4,800W surge, 3,600W on the HomePower 3000 with 7,200W surge
Why it mattersThe expansion port earns its money only if you know you'll pass 3,072Wh of storage while staying under 2,400W of draw. That's a narrow window.
That 52 dB figure belongs to charging and heavy load, not to a CPAP idling overnightA1, and there's no equivalent measured number for the HomePower 3000, so read it as a warning about when you charge rather than a gap between the two. Charge the EcoFlow during the day, or run Quiet Charging and accept the longer refillA1, and the night stays quiet.
CPAP Overnight draws 320Wh: 18% of the DELTA 2 Max's usable energy, 12% of the HomePower 3000'sBoth units are listed at 30 dBA and both switch over in 20msReviewers measured the DELTA 2 Max at around 52 dB under heavy load or while charging, with a Quiet Charging mode that trades noise for charge timeA1
Why it mattersIf a CPAP is genuinely the whole job, buy the DELTA 2 Max, keep the $350, and don't start a charge at bedtime.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: 6,144 kWh of rated lifetime energy against 12,288 kWh, which is what turns a $350 sticker gap into 15 cents per kilowatt-hour against 10.
cost / lifetime kWh
Two batteries, and one of them delivers twice as much electricity before it retires. 2,048Wh times 3,000 cycles is 6,144 kWh. 3,072Wh times 4,000 cycles is 12,288 kWh. The capacity edge and the cycle edge multiply rather than add, which is how a 26% price difference produces double the output.
The warranties are identical at five years, so that column decides nothing. Spread across those years the DELTA 2 Max costs $190 a year and the HomePower 3000 costs $240, and the extra $50 covers 1,024Wh more storage and 1,200W more inverter. Neither cell is going to expire inside the warranty regardless: at one full cycle a day the EcoFlow reaches its rating in 8.2 years and the Jackery in 11.
Your Life, Your Pick
Selected because: The HomePower 3000 takes four of the six scenarios and ties the CPAP night, and the 2,100Wh camping weekend is the one the DELTA 2 Max cannot finish.
Four of the six go to the HomePower 3000, the CPAP night is a dead heat, and one scenario beats both. The camping weekend is the one worth stopping on: 2,100Wh asked of a 2,048Wh battery is short on the nameplate alone, and once you account for what an inverter actually delivers, that weekend needs 121% of what the DELTA 2 Max can give. There is no careful-usage version of that. The load is bigger than the box.
The blackout should move any home-backup buyer. Both units clear eight hours and both switch over in 20 milliseconds, so the fridge never notices either way. The difference is what's left at dawn: the EcoFlow spends 94% of its usable energy on those eight hours and the Jackery spends 63%. Outages don't check the clock on the way in, and finishing one empty versus finishing it with a third in reserve is the difference between a rough night and a second one.
Growth Path
Selected because: Expandability is the DELTA 2 Max's only structural advantage here, and it starts 1,024Wh behind the Jackery's fixed 3,072Wh.
solar input
Expandability is the DELTA 2 Max's one card, and the deck is stacked against it. It opens at 2,048Wh, a full 1,024Wh under the HomePower 3000's fixed ceiling, so the first expansion battery is largely spent catching up to a unit you could have bought outright for $350 more. Growth that begins by paying for ground you already conceded isn't growth.
Sealed isn't a flaw when the sealed unit is the bigger one. 3,072Wh is the HomePower 3000's ceiling, and it sits above where the EcoFlow starts. Measure it against your longest unplugged stretch. If 3,072Wh clears it, the expansion port on the other unit is a feature you'll pay for and never open.
Brand Trust
Selected because: The strongest argument for the EcoFlow isn't on the spec sheet: a 4.6/5 iOS app against 2.3 to 3.3, and a community of roughly 31,000 against about 2,000.
Here's the part of the page that argues against the pick. EcoFlow's app rates 4.6 on iOS and 4.2 on Android; Jackery's sits between 2.3 and 3.3, split across two separate apps that demand a login even when you're standing next to the hardware. EcoFlow's subreddit runs about 31,000 members against roughly 2,000 for Jackery, which matters more than a membership count sounds like it should when you need someone who has already solved your problem at 11 p.m.
Support is worse, and it's worse on both sides. Jackery's warranty process is known for slow scripted replies, strict receipt requirements, and refurbished replacements for units that failed outright. EcoFlow's is polarized rather than good: smooth prepaid-label swaps for some buyers, long waits and refurbs for others, and nothing at all once the five years are up, no parts and no service. Two things take the edge off. Jackery carries the lowest reported failure and warranty-claim rate among the major brandsB2, so it's the desk you're least likely to need. And buying either unit from Costco or Amazon puts a retailer's return policy in front of the manufacturer's, which is worth more than either warranty document.
Portability & Form Factor
Selected because: 8.8 lbs separates them (50.7 against 59.52), and that is the entire weight cost of 1,024Wh more battery.
weight
8.8 lbs is the whole portability story, and it buys 1,024Wh. Run the trade and it's about 116Wh for every extra pound (1,024Wh over 8.82 lbs), which is a cheap way to buy watt-hours if you can lift them. Both units are a two-hands, bent-knees lift; one person handles the HomePower 3000 at around 60 lbs, and cell-to-body construction is why a 3kWh unit weighs that little at allB1.
Where the EcoFlow's lighter frame actually pays is repetition. If the unit lives in a truck bed and comes out every weekend, 8.8 lbs compounds across a season in a way it never does for a box that sits in a basement waiting for the grid to fail. Backup buyers can ignore weight here entirely.

A 2,100Wh weekend asks for more than the DELTA 2 Max's 2,048Wh nameplate, and once inverter losses come out it needs 121% of what the EcoFlow can actually deliver. The HomePower 3000 finishes the same trip having spent 80% of its usable energy. One of these is a two-night unit. The other is a good Saturday.

Both make it to morning, which is the part that matters, and both switch over in 20 milliseconds so the fridge never registers the outage. The gap is what's left afterward: the DELTA 2 Max spends 94% of its usable energy on those eight hours and the HomePower 3000 spends 63%. The outages that run long are precisely the ones nobody planned for.

Conclusion
August 9, 2026
Verdict: the HomePower 3000, on Power Score margin
Buy the HomePower 3000. At $1,399 against $1,049 it is 26% more money for 50% more battery (3,072Wh against 2,048Wh), 1,200W more continuous output, 400W more solar input, and 1,000 more cycles, which is why it lands at 10 cents per lifetime kilowatt-hour against the DELTA 2 Max's 15. It also wins or ties every scenario on this page, including the 2,100Wh camping weekend the EcoFlow cannot finish. The case for the DELTA 2 Max is narrow but honest: it is 8.8 lbs lighter, it refills at a wall outlet in roughly 80 minutesA2, and EcoFlow's app and owner community are the better ones by a wide margin. If your loads are small enough that 2,048Wh is never the constraint, keep the $350. Everyone else is buying the wrong box to save it.

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 2 Max rates 3.8/5 (28th percentile of 26 Large-class units), and HomePower 3000 rates 4.7/5 (84th percentile of 26 Large-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
The Jackery can't grow, and it mostly doesn't need to
3,072Wh is the HomePower 3000's ceiling, full stop, and that's a genuine loss against a unit with an expansion port. Here's the honest shape of it: the DELTA 2 Max's port opens from 2,048Wh, so the first battery you add is largely buying back the 1,024Wh the Jackery already includes, and no amount of added storage lifts the EcoFlow's 2,400W inverter or its 4,800W surge. If you know your storage needs climb past 3,072Wh while your loads stay under 2,400W, that port is worth real money and this is where the Jackery loses. Short of that, fixed capacity is just a shorter parts list.
Five years each, so this column decides nothing
Identical terms on both units, which makes the warranty a wash on paper. Priced out, the DELTA 2 Max costs $190 per warranty year and the HomePower 3000 costs $240, and that extra $50 a year is covering 1,024Wh more storage and 1,200W more output. What the paperwork won't tell you is who picks up when you actually call. That's in the brand section, and it isn't flattering to either company.
3,000 cycles against 4,000, in years you'd actually live through
Drain and refill once a day and the DELTA 2 Max reaches its rating in 8.2 years, the HomePower 3000 in 11. Cycle on weekends instead and both figures turn absurd: 28.8 years and 38.5. So cycle life decides this matchup only for daily-drain buyers, off-grid cabins and full-timers. For a backup unit that runs a handful of times a year, both packs will outlast the inverter, the app, and most likely your interest in the hobby.

Analyst note
The DELTA 2 Max is cheaper to buy, but the HomePower 3000 is cheaper to own. At $0.11/kWh over its lifetime vs $0.17/kWh, the HomePower 3000's higher cycle life and capacity make each dollar go further over the years.
Brand trust
EcoFlow
Ecosystem
The deepest catalogue in portable power: 12 to 15 models across DELTA Pro, DELTA 3 and RIVER 3, plus solar panels and smart home panels. If you expect this to be the first of several purchases rather than the only one, everything you buy later talks to everything you bought first.
Support
US-based phone, email and chat, and genuinely polarized. Some buyers get hassle-free prepaid-label replacements; others get long waits and a refurbished unit against a new claim. Once the five years are up there is nothing: no parts, no out-of-warranty service.
Community
Roughly 31,000 members on r/Ecoflow_community, plus an official forum and several Facebook groups. That's the largest user base in the category, and it's why an unfamiliar error code at 2 a.m. usually already has an answer somewhere.
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
X-Stream is the fastest charging technology in the category, and the modular ladder runs all the way to 180kWh with DELTA Pro Ultra X. Neither fact decides this matchup, but together they explain why people who start with EcoFlow tend to stay.
Worth knowing
One mark against the brand rather than against this unit: in early 2025 EcoFlow tested paywalling advanced app features before community backlash paused the plan.
Jackery
Ecosystem
12 to 15-plus models across the portable Explorer line and the HomePower backup line, plus the SolarSaga panel range and some genuinely odd swings like the Solar Gazebo and Solar Mars Bot. Broad on products, thinner on the accessory and modular side than EcoFlow's.
Support
US-based and the weak point of this recommendation: slow and scripted replies, strict receipt requirements on warranty claims, and refurbished replacements sent for units that failed outright. Buy from Costco or Amazon so a retailer's return window sits between you and that process.
Community
About 2,000 members on r/Jackery, the smallest of the major brands, though the brand recognition means YouTube coverage is plentiful. You'll find a review of your unit easily. You'll find someone who has already debugged it rather less easily.
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 worth actual money here because it's how you get a return policy that outranks the warranty desk. Dependable and widely available is the whole pitch, and on this unit the hardware backs it up.
Worth knowing
The app is the weakest of the major brands at 2.3 to 3.3 out of 5, split confusingly across a Jackery app and a Jackery Home app, both of which insist on a login even offline. Jackery also still ships NMC chemistry on a couple of older models, so if you shop elsewhere in the line, check the cycle rating on that specific unit.
Analyst note
EcoFlow builds the better software and the better community. Jackery built the better box in this particular matchup. That's an uncomfortable pairing, and it resolves the way most hardware-versus-service arguments do: you live with the hardware every day and you touch the support desk maybe once. Buy the HomePower 3000, buy it from a retailer with a real return policy, and treat the app as a nice-to-have you'll open twice.

Analyst note
Don't read the DELTA 2 Max's expandability as a straight win here: it starts at 2,048Wh, below the HomePower 3000's 3,072Wh, so a first expansion battery largely buys back capacity the HomePower 3000 already includes. It only pulls ahead if you'd grow past 3,072Wh — short of that, the HomePower 3000's larger fixed capacity is the simpler value.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 2 Max
Fan noise is the recurring complaint on the DELTA 2 Max. Reviewers put it around 52 dB under heavy load or while charging, note that Quiet Charging mode buys silence at the cost of charge time, and suggest leaving six inches of clearance for airflowA1. The counterweight is speed: 0 to 80% in about 50 minutes and a full charge in roughly 80A2.
Durability reads well. The LFP pack is rated 3,000-plus cycles to 80% with strong thermal stability, and one six-month account reported no structural degradation and a unit that felt like day oneA3. Reviewers still land on worth buying, with caveatsA4.
“Fast AC wall charging — 0 to 80% in about 50 minutes and a full charge in roughly 80 minutes.”

Jackery HomePower 3000
Compactness is the claim that keeps coming up on the HomePower 3000: cell-to-body construction, one-person carry at around 60 lbs, and a 16.4-inch width that fits spaces which reject rivalsB1. Backup performance is documented rather than promised, with a standard refrigerator kept running for nearly two days, a 55-inch TV for around 30 hours, and grid-to-battery switchover measured under 20 millisecondsB4.
Two more things are worth holding onto. Jackery posts the lowest rate of reported failures and warranty claims among the major brands in owner communitiesB2, which is the quiet counterargument to everything the brand section says about its support desk. And on longevity, reviewers rate these cells at roughly 4,000 cyclesB3, which is the same figure the cost-to-own math on this page runs on.
“Described as the world's lightest and smallest 3kWh power station thanks to an advanced cell-to-body (CTB) design — one person can carry it at around 60 lbs, and its compact 16.4-inch width fits spaces that reject rivals.”

“Described as the world's lightest and smallest 3kWh power station thanks to an advanced cell-to-body (CTB) design — one person can carry it at around 60 lbs, and its compact 16.4-inch width fits spaces that reject rivals.”

Who Should Buy Which
Buy the DELTA 2 Max if you…
- →The buyer whose entire load list is a CPAP, a phone, and a laptop. A 320Wh night is 18% of this battery, and paying $350 for capacity you'll never reach is just a donation.
- →Anyone who charges at a wall outlet and leaves in a hurry. 0 to 80% in about 50 minutesA2 is a genuinely different kind of useful from a bigger tank.
- →The person for whom 8.8 lbs decides whether the thing gets carried at all, and who's loading and unloading it most weekends rather than once a year.
- →The buyer committed to the EcoFlow ladder who will honestly climb past 3,072Wh of storage, and who accepts that 2,400W is the output ceiling no matter how many batteries hang off it.
Buy the HomePower 3000 if you…
- →The two-night camper whose weekend draws around 2,100Wh. That is more than the DELTA 2 Max holds, and the HomePower 3000 finishes the trip with a fifth of its usable energy left.
- →The home-backup buyer who wants the fridge to keep humming: nearly two days on a standard refrigerator and switchover under 20 millisecondsB4, with 63% of usable capacity spent after an eight-hour outage instead of 94%.
- →Anyone with a load between 2,400W and 3,600W, a well pump, a space heater, a shop tool. That load runs here and doesn't run on the EcoFlow at any capacity.
- →The daily-cycle buyer, off-grid cabin or otherwise, who reaches the cycle rating in 11 years rather than 8.2 and pays 10 cents per lifetime kilowatt-hour rather than 15.
If neither fits
The full-time van dweller drawing 4,685Wh a day should close this tab. That's 269% of what the DELTA 2 Max can deliver and 179% of the HomePower 3000, so both units are half-measures dressed as solutions. You want a wired house bank with alternator charging, or a system sized to cover 4,685Wh in a day with margin, not a portable box you'll resent by Wednesday.
The Bottom Line
Buy the HomePower 3000. It holds 50% more energy, delivers 1,200W more, lasts 1,000 more cycles, and costs 10 cents per lifetime kilowatt-hour against 15, all for 26% more money up front. The $350 you'd save going the other way is the most expensive $350 on this page.
Buy the DELTA 2 Max if you're honest about running small: a CPAP, a laptop, a few lights, a wall outlet within reach, and a back that notices 8.8 lbs. That buyer exists and the EcoFlow serves them properly. If your list has a refrigerator on it, or a second night, you already know which one to order.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Jackery HomePower 3000 worth $350 more than the EcoFlow DELTA 2 Max?
For almost everyone, yes. That $350 buys 1,024Wh more battery, 1,200W more continuous output, 400W more solar input, and 1,000 more cycles, which prices the extra capacity at roughly 24 cents per watt-hour against the 46 cents the DELTA 2 Max charges for its own. The exception is the buyer whose loads are small enough that 2,048Wh is never the limit. If you'll never use the top third of the bigger battery, don't pay for it.
Can the EcoFlow DELTA 2 Max run a full weekend of camping?
Not the 2,100Wh weekend this page models. That's more than its 2,048Wh rating before inverter losses, so it needs 121% of what it can actually deliver. It handles one night comfortably. If you buy it anyway, plan a mid-trip top-up: a full solar refill takes about two hours at its 1,000W input ceiling (2,048Wh at 1,000W), assuming strong sun the whole time.
Which one is better for a power outage?
The HomePower 3000. Both cover the eight-hour case and both switch over in 20ms, but the EcoFlow burns 94% of its usable energy getting there against the Jackery's 63%, and outages rarely stop where you planned. Reviewers kept a standard refrigerator running on the HomePower 3000 for nearly two days. It also holds 7,200W of surge headroom against 4,800W, which is what a fridge compressor actually asks for at startup.
Does the DELTA 2 Max's expandability make up for the smaller battery?
Only if you'll pass 3,072Wh. It starts 1,024Wh behind, so the first expansion battery is mostly buying back capacity the HomePower 3000 already includes, at additional cost on top of the $1,049. And no amount of added battery lifts the EcoFlow's 2,400W inverter or its 4,800W surge, so expansion buys you longer, never stronger.
Which of these is quieter for sleeping next to?
Both are listed at 30 dBA, and at CPAP-sized loads (320Wh overnight, 18% of the EcoFlow and 12% of the Jackery) neither is working hard enough to spin up. The one caution is charging: reviewers measured the DELTA 2 Max at around 52 dB under heavy load or while charging, with a Quiet Charging mode that trades noise for time and a recommendation to leave six inches of clearance. There's no comparable measured figure for the HomePower 3000, so treat that as a note about when you charge the EcoFlow rather than a gap between the two units.
