EcoFlow DELTA 3 1500 vs DJI Power 1000 V2
EcoFlow has deleted the 1500 from its range, which leaves one buyable unit and one real question: whether the DJI's bigger inverter is worth a third less battery.

Looking for a different matchup? EcoFlow DELTA 3 vs DJI Power 1000 V2

Solar & Off-Grid Tester, Station Arena Test Desk
Spec deltas
EcoFlow has stopped selling the DELTA 3 1500. Its product page forwards to the base DELTA 3, the one listing left is a sold-out solar bundle, and nothing in EcoFlow's current range sits at 1.5 kWh. If you arrived here mid-decision with two tabs open, one of them has closed itself: the DJI Power 1000 V2 is the only unit on this page you can actually put in a cart.
The comparison still does work, because the specs are still true and plenty of people own a 1500 or will find one sitting in retailer stock. It also tells you exactly what the market took away. The EcoFlow carried 1,536Wh and six AC sockets; the DJI carries 1,024Wh and two. That is the part of this matchup the DJI does not answer, and no amount of inverter fixes it.
What the DJI hands back is muscle. It runs 2,600W continuous where the EcoFlow ran 1,800W, peaks at 4,400W against 3,600W, and rates its UPS transfer at ≤10ms against ≤15ms. More watts, less energy. Which half you want isn't taste, it's whether your worst hour is defined by one big load or a long list of small ones.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
The DJI pays for that inverter with the pack behind it. 870Wh usable against a 2,600W ceiling is about twenty minutes at full output. It is the better starter and the weaker sustainer, and those are not the same purchase: the ceiling tells you what will switch on, never how long it stays on.
Power 1000 V2: 4,400W surge above a 2,600W continuous rating, a ratio of 1.7xDELTA 3 1500: 3,600W surge above an 1,800W continuous rating, a ratio of 2xPower 1000 V2 usable energy: 870Wh, from 1,024Wh at the flat 85% allowance
Why it mattersBuy the DJI for loads that start hard and then settle down, like a saw, a compressor fridge or a microwave. If something heavy has to run for hours, neither of these two is the size of unit you're shopping for.
So for backup the DJI isn't a slightly smaller version of the 1500, it's a different answer to the question. The load list doesn't shrink because the battery did, which means the gap gets closed with an expansion battery or it doesn't get closed. The DELTA 3 Max is the live EcoFlow sitting where the 1500 sat.
The 8-Hour Blackout profile needs 1,645WhPower 1000 V2 covers about 53% of it, 775Wh shortDELTA 3 1500 covers about 79% of it, 339Wh short, and has left EcoFlow's range
Why it mattersIf outage backup is why you're here, shop capacity or budget for expansion from the start. Don't let 2,600W of output talk you into a 1,024Wh pack.
solar input
Then the two SDC ports turn out to be a shared resource. Hang an expansion battery on one and the solar adapter on the other and there's nothing left for accessories like the 12-volt outletB7. The growth path with the bigger headline number is the more crowded one to actually build.
Power 1000 V2 solar ceiling: 1,200W, against 500W on the DELTA 3 1500Independent testing found DJI's $329 solar adapter caps input at 600W despite 1.8kW branding on the box, with panels and adapter together running close to $1,000B6The unit has two SDC ports, shared between the expansion battery and the solar accessoryB7
Why it mattersAnyone planning a solar-fed setup should price the adapter and count the ports before treating 1,200W as the spec that settles this.
rated cycles
In calendar years it still goes the DJI's way, 11 against 8.2 at one cycle a day, for the same reason: a smaller battery takes longer to use up one day at a time. Both readings are true and they point opposite ways, which is why cycle count on its own is the wrong number to shop on. And neither pack dies at the end of its rating; it settles at about 80% of original capacity and keeps going.
Power 1000 V2: 4,000 cycles of 1,024Wh, roughly 4,096 kWh over the rated lifeDELTA 3 1500: 3,000 cycles of 1,536Wh, roughly 4,608 kWh over the rated lifeRated years at daily use: 11 for the DJI, 8.2 for the EcoFlow
Why it mattersIf you want the unit that's still around in a decade, that's the DJI. Just don't read 4,000 cycles as 4,000 of the EcoFlow's.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Six load profiles, and the gap between 1,536Wh and 1,024Wh shows up differently in every one of them.
The row worth staring at is the remote workday. The Power 1000 V2 misses a 910Wh day by 40Wh, and the miss is an artifact of the accounting rather than a wall: its 1,024Wh nameplate clears the load outright, and it only slips under once the flat 85% usable allowance is applied. Leave one appliance off the desk and it finishes. That's a very different kind of failure from the van life profile, where 4,685Wh is asking a 1,024Wh unit to do something it will never do.
Everything else sorts into two piles. The overnight CPAP and the tailgate both units handle with room left over, which means capacity decides nothing there and weight, sockets and fan behaviour decide everything. The blackout and the camping weekend neither unit covers, which means you're choosing how far short to be: 339Wh on the EcoFlow against 775Wh on the DJI for the eight-hour outage. Six profiles, and capacity is the deciding variable in four of them.
What the Specs Don't Tell You
Selected because: Surge, UPS class, warranty terms and cycle life are the four places these two genuinely diverge.
rated cycles
Two of these four cards say something a buyer can act on, and two are courtesy. The surge card is the real one: the DJI's 4,400W ceiling is what starts a stubborn motor, while the EcoFlow's 2x ratio only describes how much slack it keeps above its own 1,800W rating. The UPS card matters if a desktop with unsaved work is what's being protected. Rated ≤10ms against ≤15ms is a class difference, not a measurement, and nothing on either side is a lab result; forum discussion of the 1500 pegged its cutover at the slower figure and tied it to UPS electronics carried over from the older DELTA 2A3A5.
The cycle-life card is the one most likely to mislead, and the page defuses it in the same breath by printing lifetime energy next to the cycle counts. The warranty card is a genuine dead heat on paper at five years each, which is why what's underneath the number is the only part of it still worth reading.
Growth Path
Selected because: With the 1500 out of the range, expansion is the only way to close a capacity gap, and the DJI's 1,200W solar ceiling arrives with conditions.
solar input
Both units take expansion batteries, but only one of them still has a base unit for sale, which quietly reduces this section to a question about the DJI. On its own merits the Power 1000 V2's path is the better-looking one: a 1,200W solar ceiling against 500W, and that's genuinely where it gets you off the wall socket faster on a good day.
The catch belongs on the page next to the claim. There's no built-in charge controller, so solar arrives through a proprietary $329 adapter that independent testing measured at a 600W cap against 1.8kW brandingB6, and the two SDC ports the system uses have to cover the expansion battery and the solar accessory between themB7. It expands, and it expands on DJI's terms, with DJI's parts. For an owner of the discontinued EcoFlow the calculus is different and simpler: the expansion path only means anything if the base unit you already own stays healthy, so that's the thing to protect.
Brand Trust
Selected because: One brand has the deepest catalogue in portable power and has just removed this model from it; the other is two years into the category with a drone company's support network behind it.
EcoFlow brings the deepest catalogue in portable power and, by a wide margin, the largest owner community, which is the practical value of scale: someone has already had your problem and written it down. Its support record cuts both ways, between prepaid-label replacements that go through in days and claims that come back slowly with a refurbished unit, and there's no parts or service offering once a unit is out of warranty. On a discontinued model, that last clause stops being a footnote.
DJI came to power stations in 2024 and the trade-off is visible from here. It inherits a global repair network and a hardware pedigree from drones, and it has no dedicated power-station community at all, so questions land in a drone subreddit or nowhere. The field material that exists for the Power 1000 V2 is professional testers rather than long-run ownersB0, which is a real limit on what anyone can tell you about year three.

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
Neither unit
Neither unit covers this scenario's 2,100Wh: the DELTA 3 1500 comes up 794Wh short (about 62% covered), the Power 1000 V2 1,230Wh (41%). Treat this as partial cover — enough for the essentials in it, not the whole list.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
Neither unit finishes this one. The list wants 1,645Wh; the DELTA 3 1500 gets about 79% of the way and the Power 1000 V2 about 53%, which is the difference between rationing the last couple of hours and rewriting which appliances make the list at all. Plan the load down, or plan on an expansion battery.

SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP asks for roughly 320Wh overnight, about a quarter of the DELTA 3 1500's usable energy and a bit over a third of the Power 1000 V2's, so both spend the night barely trying and capacity settles nothing. What would settle it is the fan you'll be lying next to, and neither maker publishes a noise figure, so there's no spec to hold either one to. On paper the tiebreak is weight if the unit moves between rooms: 31.3 lbs against 36 lbs.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
DELTA 3 1500
The Power 1000 V2 misses this by 40Wh, which is a rounding edge rather than a wall. Its 1,024Wh nameplate clears the 910Wh day outright; it only slips under once the flat 85% usable allowance comes off. Skip one small appliance and it finishes. The DELTA 3 1500 covers the day outright with 396Wh in hand, which is the more comfortable answer and also the one that's no longer for sale.

Game day power for the crew
DELTA 3 1500
Both handle game day; the DELTA 3 1500 keeps more in reserve (51% used vs 77%). Tailgating is a light load, though, so the number you'll feel is weight: 31.3 lbs for the Power 1000 V2 against 36 lbs for the DELTA 3 1500, from the trunk to the setup spot.

Neither unit covers this scenario's 4,685Wh: the DELTA 3 1500 comes up 3,379Wh short (about 28% covered), the Power 1000 V2 3,815Wh (19%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Conclusion
September 19, 2026
Verdict: the DJI Power 1000 V2
The Power 1000 V2 wins first by being the one you can still buy, and then it earns it on its own terms for a specific job: 2,600W continuous and a 4,400W peak start loads the DELTA 3 1500's 1,800W and 3,600W never could, and its ≤10ms rated transfer is the quicker of the two UPS classes. What it doesn't have is tank. 1,024Wh against the EcoFlow's 1,536Wh works out to 870Wh usable once the flat 85% allowance is applied, which covers about half of a 1,645Wh blackout list. Buy it if your loads are heavy and short: power tools, a microwave, a desk that must not blink. If your list is long rather than heavy, this is the wrong end of the comparison and the DELTA 3 Max is the live EcoFlow to go price instead.

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 1500 rates 5.0/5 (99th percentile of 27 Everyday-class units), and Power 1000 V2 rates 4.9/5 (92nd percentile of 27 Everyday-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Surge Power: Ratio and Ceiling Disagree
The DELTA 3 1500 holds the higher surge-to-continuous ratio (2× vs 1.7×), but the Power 1000 V2 holds the higher absolute surge ceiling — 4,400W against 3,600W. These measure different things. The ratio says how much headroom an inverter keeps above its own rating; the ceiling says how big a startup spike it can actually swallow. A motor draws a number of watts at switch-on, not a multiple of someone else's rating, so on raw starting ability the Power 1000 V2 is the stronger unit here — while the DELTA 3 1500 is the one running further below its own limit at steady state.
UPS Switchover: ≤10ms vs ≤15ms
Both list a UPS mode, at different rated speeds. The Power 1000 V2 is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The DELTA 3 1500 is rated ≤15ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. If a computer with unsaved work is the thing being protected, the stated class is worth the attention; nothing here is a lab result.
Warranty: Same Five Years, Different Fine Print
Both records carry five years, so length isn't a tiebreaker. The terms aren't symmetrical, though. DJI's five is a maximum rather than a floor, advertised for units bought from DJI's own store, so a marketplace listing may not be the same contract. EcoFlow's five years is stated flat, with one clause that matters more now than it used to: EcoFlow offers no parts or service once a unit is out of warranty, and the DELTA 3 1500 has left the range. For anyone who owns one, whatever remains of the original term is the entire support story.
Battery Lifespan in Real Years
The Power 1000 V2 is rated for 4,000 cycles vs 3,000. In real life: at daily use, that's 11 vs 8.2 years. At weekend use (twice a week), it's 38 vs 29 years. One caution reading years across different sizes: a cycle is 1,024Wh on the Power 1000 V2 and 1,536Wh on the DELTA 3 1500, so count lifetime energy — roughly 4,096 kWh against 4,608 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.

Analyst note
The DELTA 3 1500 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 Power 1000 V2 works out at $0.17/kWh over its rated life. If you already own the DELTA 3 1500, the hardware comparison still holds: over its rated life the DELTA 3 1500 delivers about 4,608 kWh and the Power 1000 V2 about 4,096 kWh. One caution on the lifespan row: the Power 1000 V2 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the DELTA 3 1500 still delivers more over its shorter horizon. Years measure wear, not usefulness.

New entrant (2024) — five power station models to date: Power 500, Power 1000 (since superseded by the V2 but still sold), Power 1000 V2, Power 1000 Mini, Power 2000. Buying a "Power 1000" listing? Check which revision it actually ships.
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
No dedicated power station community yet. Discussions happen within r/dji (~250K members, mostly drone users). Very small power-specific presence on Facebook and forums.
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
Runs quiet — 23-30dB published on most of the range (manufacturer best-case figures), at the quiet end of the category; our record carries no figure for the Power 1000 V2. Fast wall charging, quickest on the Power 1000 V2 at ~56 min — that figure is the V2's, not the whole line's. 700+ battery patents from drone R&D. SDC ports for ultra-fast DJI drone charging. Premium industrial design and build quality. LFP batteries rated for 4,000+ cycles.
Worth knowing
The app rating you'll find covers DJI Home across drones and cameras rather than this power station, so it tells you very little about running the unit from a phone. Two harder facts do matter: there's no built-in solar charge controller, so solar arrives through a proprietary adapter, and that adapter competes for the same two SDC ports an expansion battery wants.
Analyst note
The bigger ecosystem is the one that just removed this model from it. EcoFlow has the deepest catalogue in portable power and by far the largest owner community, which is worth real money when you need a cable, a firmware answer or a used part. DJI arrived in 2024 with five power models, no dedicated power-station community, and a support network built for drones being pointed at a new category. For a unit still on sale, EcoFlow's scale is an advantage. For this one, what's left of it is that there are people to ask.

Analyst note
Growth only counts if you can still buy in, and the DELTA 3 1500 is no longer sold (EcoFlow points owners to the DELTA 3 Max). That leaves the Power 1000 V2: it starts at 1,024Wh and takes DJI expansion batteries, so the ceiling moves if your needs do. The DELTA 3 1500's expandability still matters if you already own one, but it isn't a reason to pick it over the Power 1000 V2.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 1500
Field data on the 1500 specifically is thin and largely secondhand: our researcher found no Reddit, YouTube or Amazon material about this exact 1,536Wh SKU, and the two forum threads that do discuss it blocked direct fetching, so what exists is paraphrase of indexed snippets rather than verbatim owner testimonyA0. Treat everything below as directional.
What is there isn't flattering. One poster described a neighbour going through three separate 1500 units in roughly eight months, and the wider thread consensus leaned toward the DELTA 3 line drawing more failure reports than the DELTA 2 that preceded itA1A2. Posters characterised the 1500 as a DELTA 2 and DELTA 3 hybrid, with cutover electronics carried over from the older unit in a new caseA3, and pegged its UPS cutover at the slower of the two figures on this page while the standard DELTA 3 ran quickerA5. Idle draw for the line came up repeatedly, with figures argued between roughly 25-30W and a firmware fix said to cut about 40W to 17W, but our researcher could not confirm the 1500 was the model under discussion, so read it as character rather than specA4.
“Posters described the Delta 3 1500 as essentially a Delta 2/Delta 3 hybrid — UPS-cutover electronics carried over from the Delta 2, housed in a new case with what one called "larger grade B cells."”

DJI Power 1000 V2
The Power 1000 V2's evidence is unusual in shape: five independent outlets with hands-on time, including a month-long test, and no organic owner-forum chatter at all, so this is expert testers rather than the crowdB0. Quiet is the thing every one of them lands on. The fan stays near-silent even at full charging speed around 1,400-1,450W, to the point that one tester noticed the fans running by a faint warm plastic smell before hearing them, with a second reviewer reporting the same smell on first use and confirming internal temperatures were normal via the appB1B2. Build quality draws the same consistency: nothing feels cheap, and it doesn't look out of place in an officeB3.
The friction is all in the accessories and the edges. Empty to full in 56 minutes is genuinely a lunch breakB4, but the AC charging cable is a non-standard C19 that would be a problem to loseB5, and idle consumption measured around 18W, enough to empty the pack in about two and a half days if it's left sitting with nothing plugged inB8. The side-mounted handles make one-handed carrying feel unbalanced even at just over 31 lbsB11, and a few functions live in the app rather than on the unit, though the app itself is described as straightforward and reports draw, battery health and temperatureB12. The ≤10ms transfer is the upgrade testers credit most directly over the original Power 1000, specifically for home offices and networking gearB9.
“The fan barely makes a sound even during full-speed charging around 1,400-1,450W — one of the quietest power stations in its class, nearly silent under normal loads.”

- Quiet operation is the standout, consistently praised across independent reviewers, though a couple of testers separately noticed a faint smell when the fans do spin up. [Power 1000 V2 · 2 entries]
- Charging is dramatically faster than the original Power 1000, but real-world charging setups bring their own friction: a non-standard AC cable and, for solar, an expensive proprietary adapter with limited throughput. [Power 1000 V2 · 3 entries]
- The two shared SDC expansion ports are a recurring bottleneck — using them for an expansion battery or solar accessory can leave no capacity for other add-ons. [Power 1000 V2 · 2 entries]
- UPS switchover speed and overall build quality are the two things independent reviewers most directly credit as concrete improvements over the original Power 1000. [Power 1000 V2 · 2 entries]

“Idle power draw for the Delta 3 line was debated — some cite roughly 25-30W, others said a firmware update cut it from about 40W to 17W — and posters weren't sure whether the 1500 specifically had received that fix.”

Who Should Buy Which
Buy the DELTA 3 1500 if you…
- →You already own one. Nothing about it got worse when EcoFlow delisted it: 1,536Wh, 1,800W and six AC sockets is still a genuinely useful box, and the sensible move is to find out how much of the five-year term is left, because there's no out-of-warranty service path behind it.
- →You've found one in retailer stock and you want the sockets. Six AC outlets against two is the difference between running a household's worth of small things at once and playing musical chairs with a power strip. Check what warranty a third-party seller actually passes on before anything else.
- →You're shopping this page as an EcoFlow buyer, in which case the model to actually go look at is the DELTA 3 Max, the nearest thing still in the range to what the 1500 did.
Buy the Power 1000 V2 if you…
- →Your loads start hard and run short. A circular saw, a compressor fridge, a microwave at a job site: 4,400W of peak and 2,600W continuous at $699 is the strongest inverter on this page by a distance, and 870Wh usable is plenty for work that happens in bursts.
- →You want a desk that doesn't blink. Rated ≤10ms puts a desktop, a router and a monitor in the class of things that should ride through a cut, and testers point at exactly that useB9.
- →You already own DJI gear. The SDC ports charge drone batteries fast, which is a real advantage that costs nothing extra if you're in the ecosystem and means nothing if you aren't.
- →You'll carry it often. 31.3 lbs is the lighter of the two, with the caveat that the handles sit on the sides and make a one-handed lift feel worse than the number suggestsB11.
If neither fits
Anyone whose real load is a van, an RV or a whole-house outage should close this tab. The van life profile wants 4,685Wh and a camping weekend wants 2,100Wh; the larger of these two units is 1,536Wh, so both are being asked to do arithmetic they can't. Shop 2,000Wh-plus stations, or a unit with a 240V output and 30A RV socket, and treat these as the second battery rather than the first.
The Bottom Line
EcoFlow closed this comparison for you by discontinuing the 1500, so the recommendation is the Power 1000 V2 by default, and it holds up on merit for one specific buyer: 2,600W continuous and a 4,400W peak start and run things the EcoFlow's 1,800W never could, and the ≤10ms rated transfer is the faster UPS class. That inverter sits on 870Wh usable, which is roughly twenty minutes at full output. Strongest starter here, shortest breath.
If your reason for buying is a long night rather than a hard start, this page has already told you what you need to know. The 1500 covered 79% of an eight-hour outage list and the DJI covers about 53%, and no amount of surge rating changes that arithmetic. In that case take the comparison as a pointer and go price the DELTA 3 Max instead. Everyone else: the DJI is the one on the shelf, and for burst work it's the one you'd want anyway.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can you still buy the EcoFlow DELTA 3 1500?
No. EcoFlow has folded it out of the range: the product page forwards to the base DELTA 3 and the only listing left is a sold-out solar bundle. The nearest live equivalent from EcoFlow is the DELTA 3 Max. This page stays up because the 1500 is still worth comparing if you own one or find one in third-party stock.
Is the DJI Power 1000 V2 enough for an 8-hour blackout?
Only about half of one. That profile wants 1,645Wh and the Power 1000 V2 holds 870Wh usable after the flat 85% allowance, leaving it 775Wh short. It will run a fridge, a router and lights for a good stretch, but it won't carry a full essentials list through the night without either trimming the list or adding an expansion battery.
Which one starts a fridge or a power tool?
The DJI, on the number that matters for starting. Its 4,400W peak is 800W above the EcoFlow's 3,600W, and a motor pulls a fixed number of watts at switch-on rather than a multiple of the inverter's rating. The EcoFlow's higher 2x surge ratio describes how much headroom it keeps above its own 1,800W rating, which is a different and less useful question at the moment the compressor kicks in.
Is the DJI Power 1000 V2 quiet enough to sleep next to?
Probably, but nobody has published a number you can hold it to. Neither maker lists a fan-noise figure for these two units. What exists is independent testing describing the DJI as near-silent under normal loads and barely audible even charging at full speed, with a couple of testers noticing a faint warm plastic smell before they noticed any sound.
Does the DJI really take 1,200W of solar?
That's the unit's ceiling, but reaching it is the hard part. There's no built-in charge controller, so solar goes through a proprietary $329 adapter, and testing found that adapter caps input at 600W despite 1.8kW branding on the box, with panels and adapter together landing near $1,000. Budget for the accessory, not just the panels.
