Head-to-head test
EcoFlow DELTA Pro vs DJI Power 1000
Only one of these is still in its maker's range, and it's also the one whose 3,600Wh finishes the camping weekend and the eight-hour blackout the 1,024Wh Power 1000 quits partway through.

Spec deltas
The DJI Power 1000 has left DJI's range. DJI didn't abandon the line, it replaced this revision with the Power 1000 V2, and our record carries it as superseded rather than dead, so remaining retailer stock may still turn up. What you can't do is treat this page as a live two-way choice. There is one unit here you can buy new from its maker, and it's the EcoFlow DELTA Pro.
That settles the recommendation before the specs get a vote, and then the specs agree with it anyway. 3,600Wh against 1,024Wh isn't a ratio you argue around. On the weekend-camping profile the Power 1000 covers about 41% of the day and stops 1,230Wh short; on the eight-hour blackout it reaches 53%. The DELTA Pro finishes that camping weekend with 960Wh untouched.
The DJI's case was never capacity, which is worth saying out loud because it's probably why you're here. 28.7 lbs against 99 lbs is the difference between a box you carry to the bedroom and a box that stays where you parked it, and the Power 1000 takes the one scenario on this page where that matters most: the CPAP night. If that's the unit you wanted, the DELTA Pro doesn't become the right box just because it's the one still for sale. DJI's current line is where that want gets served.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
The Power 1000 doesn't get smaller as the day gets longer, it stops. Above roughly one workday of draw it covers 41% of a camping weekend and 53% of a blackout and then you're in the dark with a box that still has a screen. The DELTA Pro's 3,060Wh clears every one of those profiles, ending the camping weekend with 960Wh spare.
Power 1000: 1,024Wh nameplate, 870Wh after the flat 85% usable derate applied to every unit on this siteWeekend Camping needs 2,100Wh; 8-Hour Blackout needs 1,645Wh; Remote Workday needs 910WhDELTA Pro: 3,600Wh nameplate, 3,060Wh usable on the same derate
Why it mattersIf your worst realistic day runs longer than one workday, this stopped being a price comparison and became a capacity one.
solar input
In a multi-day outage the thing that decides whether you make it is how much you can put back between sunrise and lunch, and the DELTA Pro puts back more. The DJI's 800W also isn't a port you plug panels into: DJI ships no built-in solar charge controller, so reaching that figure means buying a separate proprietary adapter first.
DELTA Pro accepts 1,600W solar input; Power 1000 accepts 800WDELTA Pro is 3,600Wh; Power 1000 is 1,024WhDJI publishes no built-in solar charge controller: solar requires a separate proprietary adapter
Why it mattersAnyone planning to ride out outages on panels should treat the DELTA Pro's solar number as the only one of the two that works straight out of the box.
weight
So the reader who came here for the light quiet one is right about what they want and wrong about which box to buy. That want points at DJI's current lineup, not at a superseded revision you'd be sourcing from whatever stock is left, where the model name on the listing doesn't tell you which of three Power 1000s is actually in the carton.
CPAP Overnight is the single profile the Power 1000 wins: 320Wh needed, 550Wh usable left overPower 1000 weighs 28.7 lbs; DELTA Pro weighs 99 lbsThe Power 1000 is superseded by the Power 1000 V2, and three of DJI's five power stations carry 'Power 1000' in the name
Why it mattersIf weight and quiet were the draw, skip the DELTA Pro and go check which DJI revision a seller is actually shipping.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: The Power 1000 finishes two of these six profiles; the DELTA Pro finishes five, and the sixth is out of range for both.
870Wh is the number this whole page turns on. That's the Power 1000's 1,024Wh after the flat 85% usable derate this site applies to every unit, and it sits just under a working day: the remote-workday profile wants 910Wh and misses by 40. Above that line the DJI doesn't degrade, it quits. It's 1,230Wh short on the camping weekend and 775Wh short on the blackout. The DELTA Pro's 3,060Wh clears all of them, and the only profile it can't finish is the one neither can.
The two rows the DJI takes are the light ones. A CPAP night is 320Wh, a tailgate is 670Wh, and on those, everything the DELTA Pro carries above the DJI's 870Wh is just mass you moved from the trunk. That's the real shape of this matchup. Below about a workday's draw the small unit is the sensible box; above it, the big one is the only box.
Portability & Form Factor
Selected because: 28.7 lbs against 99 lbs is the one axis the Power 1000 wins outright, and it's why most people were considering it.
weight
Weight is where the DJI wins without an argument, and it wins by a lot: 28.7 lbs is a one-person, one-trip lift, while 99 lbs is a large checked suitcase you plan a route for. Our spec record doesn't track whether the DELTA Pro rolls, so if you're counting on wheeling it down a hallway, look at the product photos before you count on it.
The heavy unit does carry the sockets a heavy unit should. Five AC outlets, a 12V car socket and a 30A RV outlet on the DELTA Pro, against two AC outlets on the Power 1000 and, per our record, no 12V car socket at all. That one matters more than it sounds if the plan involved a 12V compressor fridge, which would have to run off the inverter instead and pay conversion losses on the load you'd run longest. The DJI's answer is its USB-C, the faster of the two at 140W against the DELTA Pro's 100W.
Growth Path
Selected because: Neither unit covers the 4,685Wh van-life day, and only the DELTA Pro has a route past its own 3,600Wh.
solar input
The van-life row is the useful one here because it's the row both units lose. 4,685Wh is 1,625Wh past the DELTA Pro's usable capacity and 3,815Wh past the Power 1000's. One of those gaps has a fix and one doesn't: the DELTA Pro takes EcoFlow expansion batteries, while the Power 1000 is sealed at 1,024Wh. DJI does sell expansion on newer models in the line, just not on this one.
Which is the honest way to read expandability. Not as a feature you use on day one, but as whether the box you bought has a second act. Buy the DELTA Pro and 3,600Wh is a floor. Buy the Power 1000 and 1,024Wh is the whole story, permanently.
Brand Trust
Selected because: DJI lists five power stations and three of them carry 'Power 1000' in the name, so which revision a listing ships is the thing to check.
Three of DJI's five power stations have 'Power 1000' in the name, and the one on this page is the oldest of them. That isn't trivia. It's the most useful sentence here for anyone looking at a third-party listing, because which revision arrives is decided by a seller's remaining stock rather than by the product name on the page.
Otherwise the two brands are trading different risks. EcoFlow gives you the deepest range and the largest community in portable power, plus a US phone line, with support outcomes variable enough that buying through a retailer with its own returns policy is worth doing. DJI arrived in power stations in 2024 with a drone company's manufacturing record and a global repair network built for something else, and no power-station community yet: discussion happens inside a drone subreddit. Neither fact picks a unit for you. Both are reasons to buy somewhere you can send it back.
What the Specs Don't Tell You
Selected because: Both units carry the same five-year term, and the cards that fire here cover weight, published noise ratings, a sealed pack, and what those five years actually promise.
rated cycles
Both units carry five years, which sounds like a wash and nearly is. The rest of the cards are about physical reality: a 99 lb box, a published noise rating on each side that the two makers didn't measure the same way, and a pack sealed at 1,024Wh. None of them moves the verdict. The warranty card is the one to read twice, because a five-year term that depends on where you bought it behaves differently on a revision you'd be sourcing from leftover stock.
And the honest catch on the DELTA Pro, since nothing else on this page will volunteer it: 99 lbs is not a weight you get used to, and EcoFlow's record says it offers no parts or service once the warranty is out. Five years on a box this heavy is a real ceiling, not a formality.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Capacity stops being the question about ten seconds into the arithmetic: a CPAP wants roughly 320Wh overnight, and the Power 1000 still has 550Wh in hand at sunrise. What's left to decide is the box itself, and this is the one row where the small one is obviously the right shape. One of these is 28.7 lbs and belongs on a nightstand; the other is 99 lbs and stays wherever you parked it. Both makers publish a noise rating, each measured its own way and neither taken at a 40W draw, so read them as published figures rather than as a promise about 3 a.m.
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
The Power 1000 loses this one by 40Wh, which is close enough to sting. Its 1,024Wh nameplate clears the 910Wh day outright; it's the flat 85% usable allowance every unit here gets that drags it to 870Wh and tips it under. Drop one small appliance and it finishes. That's a different failure from the camping and blackout rows, where it isn't close, but it's still a day spent watching a percentage. The DELTA Pro ends the same day with 2,150Wh it never touched.

Tailgate Party
Game day power for the crew
DELTA Pro
Both handle game day; the DELTA Pro keeps more in reserve (22% used vs 77%). Tailgating is a light load, though, so the number you'll feel is weight: 28.7 lbs for the Power 1000 against 99 lbs for the DELTA Pro, from the trunk to the setup spot.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit covers a 4,685Wh day. The DELTA Pro gets about 65% of the way there and stops 1,625Wh short; the Power 1000 manages 19%. This row isn't really a comparison, it's a sign you're shopping the wrong shelf, because full-time van power is a bigger station or a second battery. Only one of these two has the second-battery option, and even that starts from 1,625Wh behind.

Conclusion
September 19, 2026
Verdict: the DELTA Pro, on Power Score margin
Take the EcoFlow DELTA Pro, and take it for the 3,600Wh rather than anything clever. The DJI Power 1000 has been superseded by the Power 1000 V2 and carries a superseded badge on our record, so it is not a live recommendation no matter how well it tests. The specs then back the same call: 870Wh usable against 3,060Wh is the difference between a unit that covers a workday and a unit that covers a camping weekend with 960Wh still in reserve. The Power 1000's case was always weight and quiet rather than capacity, and if that is what brought you here, the honest answer is not to talk yourself into 99 lbs. It is to look at what DJI sells now.
Today the DELTA Pro is $1,799, $100 under its typical $1,899. The verdict weighs typical prices, not today's. Prices checked 16 days ago.

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 rates 3.7/5 (26th percentile of 20 Home Backup-class units), and Power 1000 rates 4.3/5 (58th percentile of 27 Everyday-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
DELTA Pro: 99 lbs Is a Commitment
At 99 lbs, this is manageable but not fun to move. That's heavier than a large checked suitcase. How much it costs you depends on whether it rolls — wheels and a telescoping handle change the job completely at this weight, and our spec record doesn't track them, so look at the product photos before you plan on carrying it from the car.
DELTA Pro: 60dB Published
60dB is about as loud as a normal conversation. The Power 1000 is rated 23dB — lower, but published by a different maker measuring its own way, so the two figures are not a like-for-like gap. For most people, fan noise around 45dB and up is where sleep starts to suffer.
Warranty: Same Five Years, Different Promises
Both records carry five years, so on paper coverage isn't a tiebreaker. The wording is where they part. EcoFlow's five years is stated plainly for this model. DJI's is an up-to figure that depends on buying from DJI's own store, and that condition is precisely the variable in play on a superseded revision you'd be sourcing from whatever stock remains: a third-party listing can leave you holding a shorter term than the spec row suggests. One thing five years doesn't cover on either side, and EcoFlow's own record says so: no parts and no service once the term runs out.

Analyst note
The Power 1000 is no longer sold, so there is no price to work its cost per kWh from, and this comparison doesn't quote one. On what you can actually buy today, the DELTA Pro works out at $0.15/kWh over its rated life. If you already own the Power 1000, the hardware comparison still holds: over its rated life the DELTA Pro delivers about 12,600 kWh and the Power 1000 about 4,096 kWh. One caution on the lifespan row: the Power 1000 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the DELTA Pro still delivers more over its shorter horizon. Years measure wear, not usefulness.

Ecosystem
Largest in portable power — 12-15 models across DELTA Pro, DELTA 3, and RIVER 3 series, plus solar panels and smart home panels
Support
US-based phone, email and chat, with outcomes that run both ways: prepaid return labels and quick swaps at one end, long waits and refurbished replacements at the other. Buying through Costco or Amazon gives you a returns window that doesn't depend on how a warranty claim goes, which is cheap insurance on a unit this size.

Unique strength
Fastest-charging technology (X-Stream), deepest product ecosystem, and most active innovation cadence. At the top of the range sit two whole-home paths: the TITAN line, one 5 kWh unit that grows to 30 kWh, and the DELTA Pro Ultra platform, which stacks batteries and inverters further — flagship paths, not line-wide features.
Worth knowing
Tested subscription paywalls for advanced app features in early 2025 before community backlash paused the plan. No parts or service offered out of warranty.
DJI
Ecosystem
Five power stations since arriving in 2024: Power 500, Power 1000, Power 1000 V2, Power 1000 Mini and Power 2000. Three of those names contain 'Power 1000', and the one on this page is the original, now superseded by the V2. A listing's title won't tell you which revision is in the carton, so check the details before you buy.
Support
Leveraging DJI's established global support and repair center network from the drone business. Generally positive reputation inherited from drone operations, but limited power-station-specific track record.
Community
There isn't one yet. Power station questions land in r/dji, a quarter-million-member room that's overwhelmingly about drones, so when something goes wrong at 11 p.m. you're searching a forum that wasn't built for the question.
App experience
Rated 3.5/5 iOS and Android (DJI Home app ratings reflect entire DJI ecosystem including drones/cameras, not power-station-specific). Users report the on-device screen is more reliable than the app.
Unique strength
Quiet is the line's signature, and DJI's published ratings sit at the quiet end of the category, though every maker measures its own way so they aren't a like-for-like promise. Past that: 700+ battery patents carried over from drone R&D, LFP cells rated past 4,000 cycles, fast wall charging, and SDC ports that refill DJI drone batteries quicker than anything else will. The build quality reads like it came from a company that makes precision hardware for a living, because it does.
Worth knowing
Two DJI-specific dependencies. There's no built-in solar charge controller, so solar runs through a separate proprietary adapter rather than straight into the unit. And the SDC fast-charge ports are DJI's own, which makes them excellent if you already fly DJI gear and beside the point if you don't.
Analyst note
EcoFlow has the largest range and the largest community in portable power. DJI showed up in 2024 with a drone company's manufacturing pedigree, a global repair network built for other products, and no power-station community to speak of. On this page, though, the brand question mostly collapses into a stock question: one of these units is in its maker's current range and one has been replaced inside it.

Analyst note
Growth only counts if you can still buy in, and the Power 1000 is no longer sold (DJI points owners to the Power 1000 V2). That leaves the DELTA Pro: it starts at 3,600Wh and takes EcoFlow expansion batteries, so the ceiling moves if your needs do. The Power 1000's expandability still matters if you already own one, but it isn't a reason to pick it over the DELTA Pro.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA Pro
The DELTA Pro's field record reads like a home appliance rather than a camping accessory: it has been run as a household's primary backup through repeated overnight outages across months, carrying a fridge, lighting and a space heater at the same timeA1A3.
Where the record gets slippery is anything measured. Our own coverage note flags that most published DELTA Pro material conflates this unit with the newer, heavier DELTA Pro 3, so the figures inside it belong to a different boxA0. That's why the two most quotable observations here, that the line rolls on wheels with a telescoping handle and prefers flat ground, and that the fans take on a high-pitched whine above roughly 2,000WA2A4, are carried as character rather than as measurement. The 99 lbs and every other spec on this page comes from our own record, not from that coverage.
“Long regarded as a gold standard for home backup — designed for high-draw appliances and full-scale battery expansion, running home essentials like a fridge, lighting, and a space heater through outages.”

DJI Power 1000
The Power 1000's coverage is unusually consistent on one point: it's quiet. Reviewers place it among the quietest in its class, with sound only surfacing past 1,500W and arriving as a soft whoosh rather than a whine, and note the fan stays near-silent even at full-speed AC charging, which finishes in about 70 minutes from emptyB1B3. It also takes more than its rating promises. One test ran it at 2,400W, above the 2,200W spec, for twenty minutes without a shutdownB2.
Across a week of camping it carried a 45W compressor fridge alongside phones, laptops and lights, and it's a known favourite of drone pilotsB4. Worth knowing this is review coverage rather than years of long-term owner reports: DJI is new to power stations, and our own note on this ledger says exactly thatB0.
“Whisper-quiet operation — one of the quietest power stations in its class, nearly silent under normal loads; sound only becomes noticeable past 1,500W, and even then it's a soft whoosh rather than the high-pitched whirring you'd get from BLUETTI or EcoFlow.”

Claims are weighted by how specific they are, whether the commenter owns the unit, and how many readers agreed. Comments that mention a product under a rival's review count for more, because the commenter had no reason to be there. This is what buyers report, not our test results — for measurements we ran ourselves, see the methodology.
Who Should Buy Which
Buy the DELTA Pro if you…
- →You want one box that covers an eight-hour blackout without rationing. It finishes that 1,645Wh night with 1,415Wh still in hand, which is the difference between watching a percentage and forgetting the power is out.
- →You car-camp within carrying distance of the trunk and would rather not think about capacity. 2,100Wh of camping weekend leaves 960Wh spare, and the 12V socket and 30A RV outlet mean the fridge and the trailer both have somewhere to plug in.
- →You suspect your needs climb toward partial-home backup. 3,600Wh is the starting point and EcoFlow expansion batteries are the step after it, which is a route the sealed alternatives on this page don't have.
Buy the Power 1000 if you…
- →You already own one. Nothing here is a reason to replace it: for a CPAP night, a tailgate, or a workday you trim by one appliance, it's the right size of box and it's quiet doing the job.
- →You're looking at a third-party listing and trying to work out whether it's this unit or the newer one. That's the only question worth your time on the DJI side of this page, and the answer is in the listing details, not in the model name.
- →You were choosing on weight and quiet rather than capacity, in which case your real comparison is the DELTA Pro against DJI's current line, and the Power 1000 V2 is the unit that replaced this one.
If neither fits
If your day genuinely looks like the van-life profile's 4,685Wh, neither of these finishes it. The DELTA Pro gets about 65% of the way and the Power 1000 about 19%, and the fix is a larger station or a wired system rather than a choice between these two. At the other end, if all you need is phones and a laptop alive through one night, you're paying for capacity several times over here and a unit a fraction of this size does that job for a fraction of the money.
The Bottom Line
The Power 1000 is superseded and the DELTA Pro isn't, which decides the recommendation before the specs get a vote, and the specs then agree. 870Wh usable against 3,060Wh is the difference between a unit that covers a workday and one that covers a camping weekend with 960Wh spare, and the two rows the small unit wins, a CPAP night and a tailgate, are the two lightest loads on the page.
So: the DELTA Pro, bought for the 3,600Wh rather than for the expansion port. If what drew you to the DJI was 28.7 lbs and a fan you can't hear, the DELTA Pro won't give you that at any capacity, and the right move isn't to settle. It's to go look at the Power 1000 V2. Just don't buy the old one because the name on the listing matched.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can you still buy the DJI Power 1000?
DJI has superseded it with the Power 1000 V2, and our record marks it as replaced rather than discontinued outright, so remaining retailer stock may still appear. The page shows no price for it and we don't recommend it at any price, because the unit you'd be buying is no longer the current revision. If you're buying new from DJI, the V2 is what's on the shelf.
Which should I actually buy in 2026?
The EcoFlow DELTA Pro, if capacity is what you're after: 3,600Wh covers the camping weekend and the eight-hour blackout that the 1,024Wh Power 1000 stops partway through. If what drew you to the DJI was 28.7 lbs rather than watt-hours, the DELTA Pro won't give you that at 99 lbs, and the comparison you actually want is the DELTA Pro against the Power 1000 V2.
Which one is quieter?
Both makers publish a noise rating, and they don't measure the same way, so the published gap isn't a like-for-like difference you can count on hearing. The coverage points the same direction the ratings do: the DJI is described as near-silent until high loads, and DELTA Pro-line coverage flags a high-pitched whine under heavy draw. Treat that second one carefully, because our research note warns DELTA Pro coverage is conflated with the heavier DELTA Pro 3.
Does the DJI Power 1000 charge from solar?
Our record carries 800W of solar input for it, but DJI publishes no built-in solar charge controller, so solar charging requires a separate proprietary adapter. That makes the 800W a figure you have to buy a part to reach rather than a port you plug a panel into. The DELTA Pro takes up to 1,600W directly, which is twice the input for a pack three and a half times the size.
Can either one run a 12V fridge directly?
The DELTA Pro can: our record shows a 12V car socket and a 30A RV outlet on it, alongside five AC outlets. The Power 1000's record shows two AC outlets and no 12V car socket, so a 12V compressor fridge would have to run through the inverter instead and pay conversion losses on the load you'd leave running longest. On a multi-day trip that's a real difference, not a rounding error.
