Head-to-head test
EcoFlow DELTA 3 1000 Air vs DJI Power 1000 V2
The DELTA 3 1000 Air and Power 1000 V2 store almost the same energy — 64Wh apart — so this isn't a capacity fight. It's a wattage-ceiling fight: 500W of continuous output on one side, 2,600W on the other, and that's what decides which appliances even turn on.

Spec deltas
Store almost the same energy and land $390 apart: the EcoFlow DELTA 3 1000 Air runs $309 for 960Wh, the DJI Power 1000 V2 runs $699 for 1,024Wh. On a spec sheet, that 64Wh gap looks like the whole story. It isn't. Continuous output is 500W on one side and 2,600W on the other — a gap far larger than the capacity difference, and the one that actually decides what you're allowed to plug in.
DJI is the newer name here, having entered power stations only in 2024, but the Power 1000 V2 outguns the DELTA 3 1000 Air on cycle life (4,000 vs 3,000), USB-C speed (140W vs 18W), and expansion — it can add capacity later; the EcoFlow can't. EcoFlow answers with price and a narrower job description. Reviewers position the DELTA 3 1000 Air as a minimalist home-office UPS, not a general power stationA1A2, and at $0.11 per lifetime kWh against DJI's $0.17, it's the cheaper way to keep a CPAP, a laptop, or a router running.
Both are honest about their limits, too. Run the numbers on six real-world scenarios and neither wins a single one outright — they either both clear it comfortably or both come up short. The decision here was never about which has more battery. It's about whether your gear needs more than 500W.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
The appliance table makes the ceiling literal: a coffee maker (1,000W), a microwave (1,200W), and a space heater (1,500W) all exceed the DELTA 3 1000 Air's 500W inverter, so none of them turn on, no matter how much charge is left. The Power 1000 V2's 2,600W clears all three with headroom to spare.
DELTA 3 1000 Air: 960Wh capacity, 500W continuous outputPower 1000 V2: 1,024Wh capacity, 2,600W continuous output
Why it mattersAnyone assuming similar Wh numbers mean similar capability is shopping the wrong spec — check continuous output first, capacity second.
That ratio describes each unit's relationship to its own ceiling, not the ceiling itself. A fridge compressor or a power tool draws a fixed number of watts, not a percentage of someone else's rating, and the Power 1000 V2's 4,400W absolute surge capacity is still more than four times the DELTA 3 1000 Air's 1,000W. The smaller unit's better ratio doesn't change what it can start.
DELTA 3 1000 Air surges to 1,000W from a 500W continuous ratingPower 1000 V2 surges to 4,400W from a 2,600W continuous rating
Why it mattersDon't pick the DELTA 3 1000 Air expecting it to handle a compressor or a power tool because its surge ratio looks stronger on paper — check the absolute watts, not the multiplier.
cost / lifetime kWh
More cycles at a higher price still loses to fewer cycles at a lower one when the price gap is this wide. EcoFlow also prices in a 2-year warranty ($155 a year of coverage); DJI doesn't publish a warranty term for the Power 1000 V2 at all, so there's no equivalent number to weigh against that $390.
DELTA 3 1000 Air: $309, $0.11 per lifetime kWh, 2-year warrantyPower 1000 V2: $699, $0.17 per lifetime kWh, no published warranty term
Why it mattersIf your load fits inside 500W, the extra cycles are headroom you're paying for and not using — the DELTA 3 1000 Air is the financially rational buy for that job.
That growth path has a real-world wrinkle: testers found the Power 1000 V2 has only two shared expansion ports, so running an expansion battery and the solar adapter at the same time can leave nothing free for anything elseB7. The headroom is genuine, but it isn't unlimited plug-and-play.

Why it mattersBuyers planning to grow into partial-home backup should still pick the Power 1000 V2 for the headroom — just map out which accessories run simultaneously before assuming every port is free.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: Price gap is $390 up front and widens on a per-kWh basis — the value argument for EcoFlow starts here.
cost / lifetime kWh
$309 against $699 is the headline number, but the more honest one is cost per kWh delivered over the unit's life: $0.11 for the DELTA 3 1000 Air, $0.17 for the Power 1000 V2. That's with DJI's cycle-life advantage already priced in — 4,000 cycles at the higher price still lands behind 3,000 at the lower one.
EcoFlow backs its unit with a 2-year warranty, which works out to $155 a year of coverage if it died the day the warranty ran out. DJI doesn't publish a warranty term for the Power 1000 V2, so there's no equivalent number to hold it against — you're buying on spec sheet and brand reputation alone on that front.
What the Specs Don't Tell You
Selected because: Five hidden-gotcha cards fire for this pair (USB-C ceiling, fixed capacity, surge ratio, cycle life, noise disclosure) — the most information-dense section for this matchup.
rated cycles
Three of the five gotchas here tell the same story: DJI built the bigger machine. The Power 1000 V2's USB-C tops out at 140W against the DELTA 3 1000 Air's 18W — the difference between charging a laptop near full speed and babysitting a trickle. Its rated cycle life, 4,000 against 3,000, means it can be drained and refilled a third more times before settling to about 80% of original capacity.
The other two cut the other way, or at least complicate the story. EcoFlow's inverter surges to twice its continuous rating; DJI's surges to roughly 1.7 times its own — a proportional edge for the smaller unit, even though DJI's absolute surge ceiling (4,400W) still dwarfs EcoFlow's (1,000W). And DJI simply doesn't publish a noise spec, while EcoFlow lists under 39dB up front — a transparency gap worth flagging even before knowing whether the unlisted number is any good.
Runtime: Will It Power Your Gear?
Selected because: Output wattage, not capacity, is what actually separates these two, and the appliance table shows exactly which loads that excludes.
continuous output
Total energy is close — 960Wh against 1,024Wh — but the appliance table breaks cleanly at 500W. A coffee maker (1,000W), a microwave (1,200W), and a space heater (1,500W) won't turn on from the DELTA 3 1000 Air at all; the inverter caps out before the battery even gets asked for power. The Power 1000 V2's 2,600W rating clears all three with room to add more.
Drop below that line and the two are functionally interchangeable. CPAP machines, phones, routers, laptops, and LED lighting all run fine on either unit for a comparable stretch, which is exactly why the wattage ceiling is the whole story here, not runtime hours.
Your Life, Your Pick
Selected because: Real-world scenarios are nearly a wash (two both, four neither) — worth explaining why that reads as parity, not a tie to break.
Run six real-world scenarios and neither unit wins outright: two are close enough to call a wash (CPAP Overnight, Tailgate Party), and four leave both units short (Weekend Camping, 8-Hour Blackout, Remote Workday, Van Life Daily). That's not a coincidence. At 960Wh and 1,024Wh, these are similarly sized batteries being asked the same questions, so they land on similar answers.
The two that do fit are both light loads. CPAP Overnight needs just 320Wh — the DELTA 3 1000 Air uses 39% of its usable capacity to the Power 1000 V2's 37%, practically a rounding error. Tailgate Party is the same story at 82% against 77%. On margins that thin, price and weight make the call, and both favor EcoFlow: $390 and 9.3 lbs.
Brand Trust
Selected because: Cross-brand pair; DJI's newcomer status and a stock caveat about expansion both need addressing directly.
EcoFlow and DJI both land in the mid-to-premium bracket, arriving from opposite directions. EcoFlow has been shipping power stations long enough to build the largest ecosystem in the category. DJI entered in 2024, bringing drone-grade engineering and battery patents but only a couple of years of power-station-specific track record. Neither is the obviously safer name by default — EcoFlow has had its own stumbles, DJI simply hasn't been around long enough to have any yet.
One stock caveat on the Power 1000 V2 is worth correcting directly: it is not locked at 1,024Wh forever. DJI sells expansion batteries for this line, the same way EcoFlow does for its larger models — this particular DELTA 3 1000 Air just isn't one of the expandable ones. The real asterisks on the DJI side are a proprietary solar adapter sold separately and expansion ports that only work with DJI's own accessories.

Scenario verdicts
We ran the math on six real-world scenarios. Here's which unit survives your actual life.
SCN-01 · 2 nights · needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Two nights of camping needs roughly 2,100Wh. The DELTA 3 1000 Air would need to draw 257% of its usable capacity to cover it, the Power 1000 V2 241% — both are more than double what they actually hold. This scenario calls for a bigger battery, a mid-trip recharge, or scaling back the loadout.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
An 8-hour blackout with a fridge, router, and lights running needs about 1,645Wh. The DELTA 3 1000 Air comes up needing 202% of its usable capacity, the Power 1000 V2 189% — both fall short by roughly the same margin. Either would need a recharge partway through, or the fridge would need to come off the list.
Battery budget usedlower = more headroom
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
An overnight CPAP load is light — about 320Wh — and both units use well under half their usable capacity to cover it: 39% for the DELTA 3 1000 Air, 37% for the Power 1000 V2. At that margin, the capacity difference is noise. Price and weight are the real tiebreakers, and both favor the DELTA 3 1000 Air: $390 cheaper and 9.3 lbs lighter.
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
Neither unit
A full remote workday — laptop, monitor, router, phone — needs about 910Wh. Both units come up just short: 112% of usable capacity for the DELTA 3 1000 Air, 105% for the Power 1000 V2. Neither fails by much, but neither clears it either. A midday top-up or a lighter monitor closes the gap on either one.
Battery budget usedlower = more headroom
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
Either unit
Tailgate Party is a shorter, lighter draw — about 670Wh — and both units clear it with room to spare: 82% used on the DELTA 3 1000 Air, 77% on the Power 1000 V2. With capacity this far from the ceiling on either side, the tiebreak is what's easier to load into a truck bed — the DELTA 3 1000 Air gives up 9.3 lbs to get there.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Full-time van life needs about 4,685Wh a day, and neither of these roughly-1,000Wh units is built for that math — the DELTA 3 1000 Air would need 574% of its usable capacity, the Power 1000 V2 538%. That load profile calls for a much larger battery bank, not either unit here.

Conclusion
July 28, 2026
Verdict: the DJI Power 1000 V2
The Power 1000 V2 is the more capable machine on nearly every spec that isn't price: 2,600W of continuous output against 500W, expansion batteries against a sealed pack, and 4,000 charge cycles against 3,000. Testers also describe a premium build with genuinely quiet fan operationB1B3. None of that is close. The DELTA 3 1000 Air answers with price — $390 cheaper up front, and actually cheaper to own per kWh over its life at $0.11 against $0.17. That's real money if your entire load is a CPAP, a laptop, and a router. Buy on wattage, not price alone: anything you own that draws over 500W continuously, the EcoFlow simply can't run.

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 1000 Air rates 5.0/5 (99th percentile of 20 Compact-class units), and Power 1000 V2 rates 4.8/5 (87th percentile of 24 Everyday-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
DELTA 3 1000 Air: USB-C Tops Out at 18W
18W is enough to trickle-charge a phone but not to fast-charge a laptop — a MacBook Air alone wants 30W minimum. The Power 1000 V2's USB-C ports run up to 140W, fast enough to charge most USB-C laptops at or near full speed straight from the battery instead of through the AC inverter.
DELTA 3 1000 Air: Sealed at 960Wh
What you buy is the ceiling here — there's no expansion path, so size the DELTA 3 1000 Air for your needs up front rather than planning to grow into it later. The Power 1000 V2 starts 64Wh ahead at 1,024Wh and can add DJI expansion batteries down the line, so it has room to grow that this unit doesn't.
Surge Ratio Favors EcoFlow's Inverter, Not Its Ceiling
The DELTA 3 1000 Air surges to twice its continuous rating (1,000W from a 500W base); the Power 1000 V2 surges to about 1.7 times its own (4,400W from 2,600W). Proportionally, that favors the smaller inverter. In absolute terms it's the opposite: the Power 1000 V2's 4,400W surge ceiling is still 4.4 times higher than the DELTA 3 1000 Air's 1,000W, so it starts bigger motors and compressors the smaller unit can't touch regardless of ratio.
4,000 Cycles vs 3,000, in Real Years
At daily use, 3,000 cycles works out to about 8.2 years for the DELTA 3 1000 Air; 4,000 cycles works out to about 11 years for the Power 1000 V2. At twice-weekly use, that stretches to roughly 28.8 years versus 38.5 years — both well past any realistic ownership window. After the cycle count is reached, the battery doesn't fail outright, it settles to about 80% of its original capacity.
Power 1000 V2: No Published Noise Spec
The DELTA 3 1000 Air lists a noise level under 39dB. The Power 1000 V2's listing doesn't include one. That's a transparency gap, not necessarily a performance one, but it means buyers sensitive to fan noise are working from a public number on one side and nothing on the other.

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 across the line (manufacturer best-case figures), at the quiet end of the category. 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
Still new to the power station category — about two years of track record versus rivals with a decade-plus. There's no built-in solar charge controller, so solar input runs through a separate proprietary adapter sold apart from the unit. The SDC expansion ports are DJI-proprietary too, which limits plug-and-play value if you don't already own other DJI gear.
Analyst note
EcoFlow is the established name with the deeper ecosystem; DJI is the newcomer betting drone engineering translates to power stations. Price position is a wash — the real gap is track record, not features. On expansion specifically: the Power 1000 V2 supports DJI's expansion batteries, while this particular EcoFlow model doesn't, even though EcoFlow offers expansion on other units in its own lineup.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 1000 Air
Reviewers describe the DELTA 3 1000 Air as a minimalist, focused unit — a 960Wh LiFePO4 battery paired with a 500W inverter, built with fewer ports and features than EcoFlow's larger modelsA1. It reads less like a general power station and more like a power-protection device: a 10ms UPS switchover keeps a computer, monitor, and router alive through an outageA2.
That 500W ceiling is a real limit, not just a number on a spec sheet. Reviewers note it won't run a space heater or a hair dryer, and it's built for low-to-moderate draw devices rather than anything with a heating element or a motorA3. EcoFlow has already discontinued this exact model in favor of a more powerful standard DELTA 3, which says something about where the company sees demand headingA4.
“A 960Wh LiFePO4 unit with a 500W inverter (800W X-Boost) weighing only 22 lbs — a focused, minimalist design with fewer ports and features.”

DJI Power 1000 V2
Independent testers consistently flag quiet operation as the Power 1000 V2's standout trait — the fan is barely audible even during fast charging near its peak wattage, one of the quietest units in its classB1. A couple of testers separately noticed a faint warm, plasticky smell when the fans do spin up, even with the app confirming normal internal temperaturesB2. Build quality reads as genuinely premium — nothing about it feels cheap or fragile, and testers say it wouldn't look out of place in an office or studioB3.
Charging is the other headline: empty to full in well under an hour in testingB4. Real-world use surfaces some friction, though. The AC cable is a non-standard size that's easy to misplaceB5, the optional solar adapter is expensive and caps input well below what the box advertisesB6, and the two shared expansion ports mean a battery pack and a solar accessory can't both stay connected without giving something upB7. Left plugged in and idle, it also drains gradually over a few daysB8. None of it is disqualifying, but it's the kind of friction worth knowing about before buying in, not after.
“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.”

“A 960Wh LiFePO4 unit with a 500W inverter (800W X-Boost) weighing only 22 lbs — a focused, minimalist design with fewer ports and features.”

“With only 500W continuous output, it won't run a space heater or hair dryer — it's built for low-to-moderate draw devices.”

“EcoFlow no longer sells the DELTA 3 1000 Air; the closest successor is the standard DELTA 3 (1,024Wh LFP, 1,800W output, ~$549).”

“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.”

“It's easier to notice when the fans are on by a faint, warm, plasticky smell rather than by sound; a separate reviewer likewise noted an unusual electronics smell on first use but confirmed via the app that internal temperature stayed normal.”

“DJI gear tends to feel really premium — nothing feels cheap or fragile, and it wouldn't look out of place in an office or studio.”

“The non-standard C19 AC charging cable is just asking to get lost, since most people won't have a spare on hand the way they would for a common C13 cable.”

“Solar charging is where things get a little odd: the $329 adapter only allows 600W of solar input despite '1.8kW' branding on the box; pairing solar panels with the adapter runs close to $1,000, which is extremely difficult to justify.”

“You only get two SDC expansion ports, and if both are occupied (e.g. an expansion battery plus an MPPT solar accessory) that leaves no spare socket for something like the 12-volt cigarette outlet — described as really odd and potentially annoying in real-world use.”

“Idle/standby consumption was measured at roughly 18 watts in testing, enough to drain the battery in about two and a half days if left connected with nothing else drawing power.”

Who Should Buy Which
Buy the DELTA 3 1000 Air if you…
- →Buy the DELTA 3 1000 Air if everything you're running lives under 500W — a CPAP machine, a laptop, a router, phone charging, some lighting. Reviewers frame it specifically as a compact home-office UPS built for exactly that kind of load, not a general-purpose power stationA2A3.
- →It's also the financially rational pick for that use case: $309 up front against $699, and $0.11 per lifetime kWh against $0.17. Paying more for headroom you'll never draw on doesn't make sense.

Buy the Power 1000 V2 if you…
- →Buy the Power 1000 V2 if you need to run anything with real draw — a coffee maker, a microwave, power tools, a space heater — loads where the DELTA 3 1000 Air's 500W ceiling won't let the appliance start at all. The 2,600W continuous rating and 4,400W surge open up loads the smaller unit can't touch at any capacity.
- →It's also the pick if you expect to grow: DJI's expansion batteries add capacity past 1,024Wh later, testers describe genuinely premium build quality and near-silent fan operationB1B3, and faster charging means less time tied to a wall outletB4.
If neither fits
If your real need is a full off-grid weekend, an 8-hour blackout with a fridge running, or a full day of van life, neither of these covers it — those scenarios need 2,100Wh, 1,645Wh, and 4,685Wh respectively, against 960Wh and 1,024Wh of total capacity on these two. Look at something with meaningfully more capacity instead, or plan on a generator or solar top-up to bridge the gap.
The Bottom Line
Capacity was never the question — 64Wh apart, these two are practically twins on paper. Output was: 500W against 2,600W is the difference between a UPS box for a desk and a power station that can run a coffee maker, a microwave, or a space heater. The Power 1000 V2 wins on capability, cycle life, and room to grow; the DELTA 3 1000 Air wins on price, at less than half the cost and $0.11 against $0.17 per lifetime kWh.
If everything you own tops out under 500W, buy the DELTA 3 1000 Air and bank the $390. If it doesn't, the Power 1000 V2 is the only one of these two that actually turns the thing on.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow DELTA 3 1000 Air still available to buy?
EcoFlow has discontinued the DELTA 3 1000 Air; the closest current replacement is the standard DELTA 3, a more powerful unit in the same family. If you're comparing prices and find the 1000 Air used or heavily discounted, factor that in — you'd be buying a model the manufacturer has already moved past.
Can either of these run a microwave or a space heater?
Only the Power 1000 V2. Its 2,600W continuous output covers a microwave (1,200W) and a space heater (1,500W) with room to spare. The DELTA 3 1000 Air tops out at 500W continuous, below both loads — the inverter won't start them, regardless of how much charge is left in the battery.
Which one is cheaper to own, not just cheaper to buy?
The DELTA 3 1000 Air, on both counts. It costs $309 against $699 up front, and works out to $0.11 per lifetime kWh against the Power 1000 V2's $0.17. DJI's extra 1,000 charge cycles (4,000 vs 3,000) don't close a gap that starts $390 wide.
Does the DJI Power 1000 V2 support expansion batteries?
Yes. The Power 1000 V2 supports DJI's own expansion batteries, so capacity can grow past its starting 1,024Wh. The DELTA 3 1000 Air has no expansion path at all — its 960Wh is fixed for the life of the unit.
Is the DJI Power 1000 V2 quiet enough to sleep near, for CPAP use?
DJI doesn't publish a noise spec for the Power 1000 V2, unlike EcoFlow's disclosed under-39dB rating for the DELTA 3 1000 Air. Independent testers, though, describe the Power 1000 V2's fan as barely audible even under load, with a couple noting a faint smell rather than noise when it does spin up. Both units are overqualified for a 40W CPAP either way — the deciding factor is the undisclosed spec, not raw power.
