Head-to-head test
EcoFlow DELTA 3 vs Jackery HomePower 3000
One of these is the cheaper box and the other is the cheaper energy, and the only question that settles it is whether 870 usable watt-hours gets you through your night.

Spec deltas
The HomePower 3000 wins this, and it wins it on the one night that matters. An eight-hour blackout asks for 1,645Wh. The DELTA 3 has 870Wh to give after the flat 15% derate this site applies to every unit's nameplate, so it covers a bit over half the night and then it's a box on your floor. The HomePower ends the same night with 966Wh untouched.
The part people don't expect is that the cheaper box isn't the cheaper energy. At $629 for 1,024Wh the DELTA 3 works out to $0.54 per watt-hour; at $1,399 for 3,072Wh the HomePower is $0.46. Both packs are rated for at least 4,000 cycles, so that gap runs straight through to the end of their lives: 4,096 kWh of total energy from the DELTA 3 against 12,288 kWh from the HomePower. Whatever the DELTA 3's case is, better value per unit of power isn't it.
What the DELTA 3 owns is the box itself. 27 lbs is one hand and a trunk lift; 59.5 lbs is knees bent and a plan. It's rated ≤10ms on UPS switchover against ≤20ms, the only performance rating on this page where the smaller unit leads. And if your entire load is a CPAP, it does that job using 37% of its usable energy where the HomePower uses 12%, a distinction you will not feel once at 3 a.m.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
That puts the DELTA 3 on a knife edge rather than a slope. It lives exactly at the boundary of a single working day: everything smaller than a laptop, a router and some lights it covers comfortably, and everything larger it misses by hundreds of watt-hours, not tens. There's no band in the middle where it half-works and you adapt.
DELTA 3: 1,024Wh rated, 870Wh usable after the flat 15% derate8-Hour Blackout needs 1,645Wh; Weekend Camping needs 2,100WhRemote Workday needs 910Wh, leaving the DELTA 3 40Wh short
Why it mattersIf your worst case is bigger than one desk day, the $770 you save on the DELTA 3 buys a unit that doesn't finish the job, so spend it.
solar input
The usual reason to buy small is that small refills fast, and here that reasoning simply doesn't apply. On day two of an outage both units spend the same solar day, and only one of them ends the night with power left. The DELTA 3 would be charging all day to still come up short after dark.
DELTA 3: 500W max solar input, 1,024Wh capacityHomePower 3000: 1,400W max solar input, 3,072Wh capacityIn an eight-hour blackout the DELTA 3 finishes 775Wh short of the 1,645Wh needed
Why it mattersAnyone prepping for a multi-day outage rather than a single evening should stop treating the DELTA 3 as the nimble choice.
Capacity
Follow that to its conclusion and there's no way to assemble the Jackery's capacity out of DELTA 3s for less. Three of them reach exactly 3,072Wh for $1,647, which is $248 more than Jackery charges for one box, spread across three chargers, three sets of ports and 81 lbs against 59.5. The DELTA 3's argument was never cheaper power. It's less power, cheaply, today.
$629 for 1,024Wh is $0.54 per watt-hour; $1,399 for 3,072Wh is $0.46Both are rated for at least 4,000 cycles, giving 4,096 kWh and 12,288 kWh of lifetime energyLifetime cost works out at $0.13 per kWh for the DELTA 3 and $0.11 for the HomePower
Why it mattersBuy the DELTA 3 on budget if you must, but buy it knowing you're buying less energy rather than better value.
A CPAP at 40W sits well below the 200W mark where the DELTA 3's fans reportedly stay off, which is the one low-load finding attributable to this exact model rather than a siblingA1A0. Paying $770 more to use 12% of a battery instead of 37% buys nothing you can perceive at 3 a.m., and it costs you 32.5 lbs of carry every time the unit moves, 59.5 against 27.
CPAP Overnight needs 320Wh, about 40W for eight hoursThat's 37% of the DELTA 3's usable energy and 12% of the HomePower'sUnder 200W the DELTA 3's fans often stay off entirely, and at 500-800W they're barely audible from three feetA1
Why it mattersIf the machine you're protecting is a CPAP and nothing else, close the tab and take the DELTA 3.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: The DELTA 3 covers the CPAP night and game day but misses a camping weekend by 1,230Wh and an eight-hour blackout by 775Wh, which is what actually decides this pairing.
Read down the rows and the DELTA 3 has one good day in it. A CPAP night uses 37% of what it can give, game day 77%, and then the wall arrives: a remote workday wants 910Wh against 870Wh usable, and after that every scenario is a rout rather than a squeeze. 775Wh short on the blackout, 1,230Wh short on the weekend. The gap between passing and failing here is a single small appliance.
The workday row is the one to sit with, because it's the only place the derate does the damage rather than the battery. The DELTA 3's 1,024Wh nameplate clears a 910Wh day; the flat 15% allowance applied to every unit on this site is what pushes it under. Unplug one thing and it finishes, which is exactly the kind of fiddling you don't want to be doing at 4 p.m. with a deadline. The HomePower never approaches the line, and there's a plain reason to pay for that: margin is the feature you notice only when you don't have it.
Portability & Form Factor
Selected because: 27 lbs against 59.5 is the DELTA 3's entire counter-argument, and it's a good one if the unit moves more than it sits.
weight
59.5 lbs is the best thing anyone can say about a 3kWh box, and it's genuinely impressive. It's also more than double the DELTA 3's 27 lbs, and it's a one-person carry in the sense that one person can do it, not that they'll enjoy it. Reviewers put its width at 16.4 inches, which matters more than it sounds when the destination is a closet shelf or the gap behind a breaker panelB1. Published weights for it run from our listed 59.5 up to 63.9 lbs depending on the source, so budget for the high endB0.
The honest test is where the unit lives. On a shelf beside the panel, weight is a problem you solve once and then forget. In the back of a car that gets loaded every other weekend, it's a tax you pay every trip, and the DELTA 3's 27 lbs is the difference between grabbing it and thinking about it.
Lifetime Value
Selected because: Same 4,000-cycle rating on both packs, so the price-per-watt-hour gap survives to end of life: $0.13 per lifetime kWh for the DELTA 3 against $0.11 for the HomePower 3000.
cost / lifetime kWh
Both packs are rated for at least 4,000 cycles, which at a cycle a day is roughly 11 years, or about six years past the five-year warranty term either brand will honor. So longevity isn't the axis. Neither is cost per unit of energy, because that also favors the bigger unit once you divide price by total lifetime kWh.
Which leaves the only cost question worth asking: do you need the energy you'd be buying? $1,399 for 3,072Wh is the better deal per watt-hour and the wrong purchase if your ceiling is a CPAP and a phone. Cheaper-to-own and cheaper-to-buy are different claims, and the DELTA 3 only ever had the second one.
Growth Path
Selected because: The DELTA 3 takes expansion batteries and the HomePower 3000 is sealed at 3,072Wh, but the DELTA 3 starts 2,048Wh behind, so the first battery you add is catching up.
solar input
Here's the honest catch on our pick: what you buy is the ceiling. The HomePower 3000 is sealed at 3,072Wh with no expansion port, so if your needs grow, your upgrade path is a second unit. The DELTA 3 is the one with a future, and it really does take EcoFlow expansion batteries.
The trouble is where it starts. At 1,024Wh it sits 2,048Wh below the HomePower, so the first expansion battery you buy is spent catching up to capacity the Jackery already includes, not getting ahead of it. Expandability only starts paying once you'd pass 3,072Wh, and if that's the plan, say so now and shop above both of these. A growth path that begins two thousand watt-hours in arrears isn't much of a head start.
Brand Trust
Selected because: Our pick ships with the weaker app and the smaller community, which is worth knowing before you choose where to buy it.
Choosing the HomePower means choosing the worse software and the quieter community. Jackery's apps rate 2.3 to 3.3 out of 5 across iOS and Android, with a confusing split between the Jackery and Jackery Home apps and a mandatory login even when you're standing next to the unit offline. EcoFlow's app sits at 4.6 on iOS, and its subreddit has around 31,000 members against roughly 2,000 for Jackery's, which is the difference between finding your problem already solved and posting into a quiet room.
Support is weak on both sides of this page, so the hedge is the same either way: buy from Costco or Amazon and let the retailer's return desk be your first line rather than a support queue. Two things tilt back toward Jackery. Its retail distribution is the widest in the category, so that return desk is genuinely available. And one reliability roundup puts Jackery at the lowest rate of reported failures and warranty claims among the major brandsB2, which is a reasonable trade if it means you never have to test the support line. Worth knowing on the other side: EcoFlow offers no parts or service once the warranty is done.

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 3000
870Wh usable against the 2,100Wh a weekend asks for is two-fifths of the trip, so the DELTA 3 stops before you do, 1,230Wh short. The HomePower 3000 packs up with 511Wh still in hand. Shorten the trip to one night and the arithmetic changes completely, so price the box against the trip you actually take.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
HomePower 3000
This is the row the price gap has to justify, and it does. The night needs 1,645Wh; the DELTA 3 has 870Wh usable and covers a little over half of it, ending 775Wh short with the fridge still humming and nothing left to hum with. The HomePower 3000 finishes with 966Wh spare, which is margin for the outage running long.

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
At roughly 40W for eight hours, this asks 320Wh, so both units clear it several times over and capacity has stopped being the question. What's left is the object beside your bed: 27 lbs you pick up with one hand, or 59.5 lbs you plan a route for. The engine calls this one for both, and the tiebreak is simply the one you'd rather move.
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
HomePower 3000
The DELTA 3 misses this by 40Wh, which exists only because of the flat 15% derate applied to every unit here; its 1,024Wh nameplate clears the 910Wh day outright. Unplug one small thing and it finishes. The HomePower 3000 never comes near the line, with 1,701Wh spare, and if you'd rather not do mental arithmetic at 4 p.m., that's the whole argument.

LOAD Laptop 60W×8h · External Monitor 30W×8h · Router + Modem 20W×8h · Phone Charger 15W×2h
SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
HomePower 3000
Both handle game day; the HomePower 3000 keeps more in reserve (26% used vs 77%). Tailgating is a light load, though, so the number you'll feel is weight: 27 lbs for the DELTA 3 against 59.5 lbs for the HomePower 3000, from the trunk to the setup spot.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit finishes this one. 4,685Wh a day leaves the DELTA 3 covering 19% and the HomePower 3000 56%, so this is the wrong shelf rather than a close call. A van eating this much wants a larger station or a properly wired house bank, not whichever of these two loses by less.

Conclusion
September 13, 2026
Verdict: the HomePower 3000, on Power Score margin
Take the HomePower 3000 if you're buying for an outage or a weekend away. It needs 1,645Wh to cover an eight-hour blackout and 2,100Wh to cover a camping weekend, and the HomePower finishes both with 966Wh and 511Wh still in the tank while the DELTA 3 lands 775Wh and 1,230Wh short. Those aren't near misses you can trim your way out of. The $770 you'd save is real money, and it buys a unit that covers a CPAP, a tailgate, and a laptop-and-router workday if you unplug one small thing. Past that, the DELTA 3 stops, and it stops during the exact event you bought a power station for. Confidence sits at 7 rather than 9 because the HomePower is the heavier box by more than double, it's rated ≤20ms on UPS switchover against the DELTA 3's ≤10ms, and Jackery's app and support are the weaker half of this pairing. If your load list genuinely tops out below 870Wh, none of the Jackery's advantages are things you'll ever touch.

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 4.4/5 (65th percentile of 27 Everyday-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.
Sealed at 3,072Wh, and the alternative starts 2,048Wh back
The HomePower 3000 has no expansion port, so 3,072Wh is the ceiling you're buying. The DELTA 3 genuinely does take EcoFlow expansion batteries, which makes it the unit with a future on paper. The catch is its starting line: at 1,024Wh it's 2,048Wh behind, so the first battery you bolt on is spent catching up to capacity the Jackery already includes. Expansion only pays here if you'd grow past 3,072Wh, and that's a decision to make before you buy, not after.
UPS: a ≤10ms rating against a ≤20ms one
Both are ratings, not stopwatch results, so read them as classes rather than measurements. For a router, a modem or a TV, either handoff is invisible. The place the class earns attention is a desktop PC with unsaved work, where the fussiest power supplies sit right around the 20ms mark. If that machine is the reason you're buying, the DELTA 3's tighter rating is the only performance figure on this page where the smaller unit leads.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The HomePower 3000's figure is a maximum rather than a guarantee — it depends on registering the unit with Jackery, which is what extends the base term to the full period. Worth saying because the per-dollar framing can suggest otherwise: the DELTA 3 works out at 7.9 years of cover per $1,000 spent against the HomePower 3000's 3.6, but that spread is the price gap, not the terms.

Analyst note
The DELTA 3 is cheaper to buy, but the HomePower 3000 is cheaper to own. At $0.11/kWh over its lifetime vs $0.15/kWh, the HomePower 3000's higher cycle life and capacity make each dollar go further over the years. One thing to know reading the table: both carry the same 4,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.
Brand trust
EcoFlow
Ecosystem
The deepest catalog in portable power: 12 to 15 models across the DELTA Pro, DELTA 3 and RIVER 3 lines, plus panels and smart home panels, so a second unit or an expansion battery is always in stock somewhere.
Support
US phone, email and chat, with genuinely split outcomes. Some claims end in a hassle-free prepaid label and a replacement; others turn into long waits and a refurbished unit against a new-product claim. Buying through Costco or Amazon gives you a return desk as a fallback.
Community
The busiest community in the category, with roughly 31,000 members on the main subreddit plus Facebook groups and an official forum, which usually means your question has already been answered.
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
Fast charging and a fast product cadence. X-Stream charging and the constant model refresh are why an EcoFlow spec sheet tends to look newer than its price suggests.
Worth knowing
EcoFlow tested paywalling advanced app features in early 2025 and paused the plan after backlash, and it offers no parts or service once the warranty expires. Plan on the warranty being the whole of the support story.
Jackery
Ecosystem
12 to 15 or more models across the portable Explorer line and the HomePower home-backup line, plus the SolarSaga panel range and some genuinely odd form factors like the Solar Gazebo.
Support
The weakest part of owning a Jackery: scripted responses, strict receipt requirements on warranty claims, and refurbished replacements for units that failed out of the box. Buy it somewhere with a real return policy and treat Jackery support as the second option.
Community
The smallest owner community among the major brands, at around 2,000 members on its subreddit. YouTube coverage is plentiful because of brand recognition, but peer troubleshooting is thin.
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
Availability. Costco, Home Depot, Best Buy and Amazon all carry it, which makes it the easy unit to buy, compare in person, and return.
Worth knowing
The app experience trails the category badly, at 2.3 to 3.3 out of 5 across platforms, with two separate apps and a mandatory login even when you're standing beside the unit. A couple of older Jackery models still ship NMC cells with shorter rated lives, so check the cycle rating on whatever you actually buy.
Analyst note
The brand column is where the DELTA 3 wins on our pick's own terms: better app, bigger community, deeper ecosystem. Jackery's counter is that its units are the easiest to buy and return, and that its failure rate is well regarded. Neither support desk is a reason to choose, so make the decision on the hardware and then buy from a retailer whose return policy you'd actually use.
Growth path
DELTA 3
EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 1,024Wh.
Accepts up to 500W of solar. Suitable for a 1-2 panel setup.
Generous port selection supports complex multi-device setups.
Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.
HomePower 3000
FIXED CAPACITYFixed at 3,072Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.
Accepts up to 1,400W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Don't read the DELTA 3's expandability as a straight win here: it starts at 1,024Wh, 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 3
Field data on the standard DELTA 3 is thin, and it's worth saying plainly: most published testing covers the Plus, Max and Ultra variants, which differ in capacity and, on the Plus, in fan behaviorA0. The sentiment on file for this specific model is preliminary, and we are treating it that wayA0.
What is attributable to this unit is the low-load behavior, and it's the best thing on its record: under 200W the fans often stay off completely, and between 500W and 800W they're barely audible from three feet awayA1. The UPS handoff on file was observed on a sibling that shares the same ≤10ms rating rather than on this box, so read it as character rather than proof that this unit does the sameA2A0.
“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.”

Jackery HomePower 3000
The HomePower 3000's reputation is built on being small for what it holds. It's described as the lightest and most compact 3kWh station going, thanks to a cell-to-body design that gets it down to a one-person carry at around 60 lbs and a 16.4-inch width that fits spaces which reject its rivalsB1. Published weights vary from about 59.5 to 63.9 lbs depending on who measuredB0.
On the job it does the boring thing well: a standard refrigerator kept running for nearly two days, a 55-inch TV for around 30 hours, and a grid-to-battery handoff measured under its rated 20msB4. Reliability commentary is favorable, with one roundup placing Jackery at the lowest rate of reported failures and warranty claims among the major brandsB2, and the LFP cells rated around 4,000 cycles, matching the figure we list, though that cycle source couldn't be pinned to this exact SKUB3B0.
“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.”

“Solid home backup — kept a standard refrigerator running for nearly two days and a 55-inch TV for around 30 hours, with a grid-to-battery UPS switchover measured under 20 milliseconds.”

Who Should Buy Which
Buy the DELTA 3 if you…
- →The CPAP-only buyer. 320Wh a night against 870Wh usable means you'll never see the bottom of it, and the fans reportedly stay off at that loadA1.
- →Anyone who carries the unit more than they use it. 27 lbs is a one-hand lift out of a trunk and over a tailgate, and game day only asks 77% of what it has.
- →The person protecting a desktop PC with unsaved work, where the ≤10ms rating rather than ≤20ms is the reason to choose.
Buy the HomePower 3000 if you…
- →Anyone buying for an actual outage. 1,645Wh covered with 966Wh spare, and a standard fridge kept going for nearly two days in testingB4.
- →The camping weekend at 2,100Wh, finished with 511Wh in reserve instead of a unit that quits at 41% of the trip.
- →The buyer who wants the refill to keep pace with the battery: 1,400W of solar input against 500W means three times the capacity comes back in roughly the same sunny afternoon.
If neither fits
If your day looks like van life at 4,685Wh, both of these lose. The DELTA 3 covers 19% of it and the HomePower 56%, so you'd be waking up to a dead box either way. That's a job for a larger station or a permanently wired house bank sized to the load, and it's worth pricing that properly before you spend $1,399 on a unit you'd outgrow in a week.
The Bottom Line
Take the HomePower 3000. An eight-hour blackout wants 1,645Wh and a camping weekend 2,100Wh, and the DELTA 3 arrives with 870Wh usable to both, which is the specific way a power station disappoints you. The Jackery finishes each with room left, and because both packs carry the same at-least-4,000-cycle rating, it's also the cheaper unit per unit of energy across its whole life rather than in spite of its price.
The DELTA 3 is still the right box for a narrower job, and the narrower job is common: a CPAP, a tailgate, a desk day where you'll unplug one thing. 27 lbs and a tighter UPS rating are real advantages for that buyer. But nobody buys a 3kWh-class station because they're worried about a light evening. If the reason this tab is open is the night the grid goes down, the unit that survives it is the Jackery.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Jackery HomePower 3000 worth $770 more than the EcoFlow DELTA 3?
Yes, if you're buying for a blackout or a weekend off-grid. The DELTA 3 misses an eight-hour outage by 775Wh and a camping weekend by 1,230Wh, so the money buys the difference between a unit that finishes and one that doesn't. It also buys cheaper energy, not just more of it: $0.46 per watt-hour against $0.54. If your real load is a CPAP, a phone and a laptop, the extra $770 buys margin you'll never draw on.
Will the EcoFlow DELTA 3 run a fridge through an 8-hour blackout?
No. That scenario needs 1,645Wh and the DELTA 3 has 870Wh usable once you apply the flat 15% derate, so it covers a bit over half the night. The HomePower 3000 clears it with 966Wh to spare, and in testing it kept a standard refrigerator running for nearly two days. Starting the fridge isn't the issue for either unit, both have the surge headroom; finishing the night is.
Can I just add expansion batteries to the DELTA 3 instead of buying the HomePower 3000?
You can, since the DELTA 3 does accept EcoFlow expansion batteries, but check the arithmetic before you commit. It starts at 1,024Wh, which is 2,048Wh below the HomePower 3000, so your first expansion purchase mostly buys back capacity the Jackery includes in the box. Expansion only puts you ahead if you'd grow past 3,072Wh, and at that point you should be shopping a tier up from both units.
Which one is better for a CPAP machine?
The DELTA 3, and it isn't close on the things that matter overnight. A CPAP is roughly 40W for eight hours, or 320Wh, which uses 37% of the DELTA 3's usable energy and 12% of the HomePower's, so both cover the night and capacity stops being a factor. What's left is a 27 lb box at $629 versus a 59.5 lb box at $1,399, plus the DELTA 3's tendency to keep its fans off below 200W.
Can one person carry the Jackery HomePower 3000?
One person can, but plan the lift. Our spec sheet lists 59.52 lbs and published figures run as high as 63.9 lbs, and it's regularly called the lightest 3kWh station available thanks to its cell-to-body construction. Its 16.4-inch width is the more useful number if it's going on a shelf or into a closet. The DELTA 3 at 27 lbs is the one you pick up without thinking about it.
