Superseded — buy the V2
DJI has superseded the Power 1000 with the Power 1000 V2 — same $699, with 2,600W output against 2,200W. The original may still be purchasable while stock lasts, but unless it is meaningfully discounted, buy the V2.
Power 1000 V2 · $699.00Spec deltas
Buy the DELTA 3 Max. At $899 against the Power 1000's $699 you're paying $200 more, and what that $200 buys is a second 1,024Wh: 2,048Wh in total against the DJI's 1,024Wh. Everything below is about whether anything the DJI does is worth turning that down.
The DJI has one argument and it's a good one. 28.7 lbs against 50.7 lbs is the difference between carrying a box and staging a lift, and reviewers put the Power 1000 among the quietest stations in its class, with sound only becoming noticeable past 1,500WB1. One test ran it at 2,400W, above its own 2,200W rating, for twenty minutes with no shutdownB2. This is not a weak unit. It's a small one.
One thing to settle before you click buy: which Power 1000 you're being sold. Our brand record lists DJI's current line as the Power 500, Power 1000 V2, Power 1000 Mini and Power 2000, and notes separately that battery expansion exists on the Power 2000 and the V2 but not on the earlier Power 1000. The unit priced here is the base model. That isn't a clearance story, incidentally: at 68 cents a watt-hour against the DELTA 3 Max's 41, the DJI is the more expensive energy on this page, and nothing gets discounted to a premium. It's a listing to confirm, not a unit to write off.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
Cheap capacity normally gets paid for somewhere: thinner cells, a shorter warranty, a lower cycle rating. Not here. Both units are rated for 4,000 cycles and both carry five years, so the extra battery arrives with no bill attached to it.
DELTA 3 Max: $899 for 2,048WhPower 1000: $699 for 1,024WhBoth rated 4,000 cycles, both covered for 5 years
Why it mattersIf $899 clears your budget at all, capacity has stopped being the question and weight is the only thing left to argue about.
continuous output
No appliance on your list will start on one of these and refuse on the other. The entire difference between them is how long the appliance stays running, and that is 2,048Wh against 1,024Wh.
DELTA 3 Max rated 2,400W continuous, 4,800W surgePower 1000 rated 2,200W continuous, 4,400W surgeThe Power 1000 was tested at 2,400W for twenty minutes without shutting downB2
Why it mattersStop comparing inverter numbers. This is a runtime decision and nothing else.
That failure is produced by a flat constant, not by the battery. Field use says the same thing: the Power 1000 ran a 45W compressor fridge plus phones, laptops and lights across a week-long camping tripB4. The scenario a DJI buyer should actually worry about is the eight-hour blackout, where the gap runs to hundreds of watt-hours rather than forty.
Remote Workday needs 910WhThe Power 1000 holds 1,024Wh nameplate and is scored 40Wh shortThe scenario table rates usable capacity at a flat 85% of nameplate for every unit, putting the DJI at 870Wh
Why it mattersDon't let the Remote Workday result push you toward the EcoFlow. Let the blackout do it, if a blackout is why you're shopping.
weight
Its weight advantage and its capacity ceiling describe the same buyer: someone who moves it often and asks little of it. The problem is that the most common reason people buy one of these is the blackout, and a blackout is the one job where the unit never moves. It goes on the floor beside the router and stays there. 28.7 lbs buys you nothing in that room.
Power 1000: 28.7 lbs. DELTA 3 Max: 50.7 lbsThe Power 1000's clean wins are small loads: CPAP Overnight at 320Wh, Tailgate Party at 670WhWeekend Camping asks 2,100Wh and leaves the Power 1000 1,230Wh short on the derated basis
Why it mattersCarry it weekly and the Power 1000 is the right box. Store it in a closet waiting for the grid to fail and the 50.7 lbs never costs you a thing.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: 2,048Wh against 1,024Wh at $899 against $699 is the trade you're actually making. The rest is detail.
continuous output
The gap you'll feel isn't a number on paper, it's what happens at hour six. The DELTA 3 Max covers the 1,645Wh eight-hour blackout the table models; the Power 1000 brings 870Wh of derated usable to that same load and then you're deciding what to unplug. Neither outcome is dramatic. One is a boring evening and the other is a managed one.
A small battery you can refill quickly is a different animal from a small battery you can't. AC charging on the Power 1000 runs about 70 minutes from empty, roughly 50 minutes to 80%B3, and it takes 800W of solar against the DELTA 3 Max's 1,000W. If you're plugged in every night, the capacity gap narrows. If you're on day three of an outage with no grid to plug into, it doesn't narrow at all.
Your Life, Your Pick
Selected because: Three of the six go to the DELTA 3 Max on capacity, one to the Power 1000, and two are out of reach for both units.
Read the percentages as a ranking, not a measurement. Every unit here is scored at a flat 85% of nameplate, the same constant applied to both boxes, and on the Remote Workday that constant is doing all the work: 1,024Wh of nameplate covers a 910Wh day, and the 40Wh miss is a quarter of the 154Wh the derate removes before the load is even counted.
The two 'neither' results are not the same kind of neither. Weekend Camping wants 2,100Wh and the DELTA 3 Max misses by 359Wh on the derated figure, only 52Wh against its raw 2,048Wh nameplate. Van Life Daily wants 4,685Wh, more than double what the bigger unit holds. One of those is a weekend you'd trim slightly. The other is a category error.
Portability & Form Factor
Selected because: 28.7 lbs against 50.7 lbs is the Power 1000's whole case, and it's a real one if the unit travels.
weight
50.7 lbs is a bent-knees lift with both hands and a plan for where you're setting it down. 28.7 lbs you carry in one trip with a cooler in the other hand. That's not a spec-sheet difference, it's a behaviour difference: the heavy one gets moved when there's a reason, the light one gets moved because it's there.
So the honest question isn't which is lighter. It's how many times a year you pick it up. Twice a summer and 50.7 lbs is an annoyance you'll forget by August. Every weekend and it's the reason the thing quietly stops leaving the garage.
Lifetime Value
Selected because: Both units are rated for 4,000 cycles, so this table can only restate the purchase price rather than add to it.
cost / lifetime kWh
This table can't separate these two, and it's worth knowing why. Both are rated for 4,000 cycles, so cost per lifetime kilowatt-hour is just the purchase price per watt-hour divided by the same number on both sides: 10 cents for the DELTA 3 Max, 17 for the Power 1000. It reorders nothing you didn't already know from the sticker.
The lifespan row is worse than uninformative. Both units print 11 years of daily cycling and 38.5 years of weekend use, identical figures across a 2x capacity gap, because that arithmetic divides 4,000 cycles by a calendar and never asks how big the battery is. Draw the 1,645Wh the blackout models and you've used about 80% of one DELTA 3 Max cycle (1,645 of 2,048Wh) or better than one and a half Power 1000 cycles (1,645 against 1,024Wh). Same cycle rating, and the smaller unit spends it faster.
Growth Path
Selected because: The DELTA 3 Max takes expansion batteries and the Power 1000 is sealed at 1,024Wh, which matters less than it sounds.
solar input
The DELTA 3 Max takes EcoFlow expansion batteries and the Power 1000 doesn't, but be careful how much weight that carries. Sealed at 1,024Wh is not a missing feature in a one-kilowatt-hour station; it's the complete form of one. The Power 1000 isn't the EcoFlow with a socket deleted. It's a different size of thing.
Where expansion earns its keep is if you're buying with the house in mind, and that's a bigger step than the phrase makes it sound: you'd be buying batteries, not checking a box. The useful version of the argument is narrower. If you already suspect 2,048Wh won't be enough, the unit that can grow is cheaper than buying twice.

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
Neither box finishes the 2,100Wh weekend, but call the two misses what they are. The DELTA 3 Max is 359Wh short on the derated basis and only 52Wh short against its raw 2,048Wh nameplate, which is one item off the list. The Power 1000 is 1,230Wh short, which is another whole battery. Both get marked as failures. Only one of them is a real one.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
DELTA 3 Max
The DELTA 3 Max covers all 1,645Wh of this and finishes with 96Wh of derated usable in hand, so call it a pass rather than a comfortable one. The Power 1000 brings 870Wh usable to the same load and lands 775Wh short, which is an evening of triage: router and lights, then choices. If blackouts are why you're shopping, this row is the entire argument.

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
Power 1000
Both units sleep through this without noticing. The night draws 320Wh, leaving the Power 1000 with 550Wh of derated usable and the DELTA 3 Max with 1,421Wh, so capacity isn't the question and the percentages are a formality. The DJI takes the row on what you'd be paying for the difference: $899 and a 50.7 lb station against $699 and a 28.7 lb one, to reserve capacity a CPAP will never reach. If the mask is this machine's only job, the smaller box is the right box.

LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
DELTA 3 Max
The Power 1000 is scored as a miss here and it shouldn't read as one. The day needs 910Wh and the DJI holds 1,024Wh, so nameplate covers it by 114Wh. The 40Wh it's marked short by comes from the flat 85% derate, which counts that 1,024Wh as 870Wh usable, a 154Wh haircut applied before the load is even counted. The DELTA 3 Max wins the row on the arithmetic and finishes with far more in reserve, but a real desk day on the DJI ends with the battery low, not dead.

Tailgate Party
Game day power for the crew
DELTA 3 Max
Both get through game day. The 670Wh here leaves the DELTA 3 Max 1,071Wh of derated usable spare and the Power 1000 200Wh, and on a load this light that reserve is a number rather than an experience. The row goes to the DELTA 3 Max. The parking lot goes to the Power 1000, which weighs 28.7 lbs against 50.7 and is the one you'd rather walk from the car.

Van Life Daily

Neither unit
Out of class for both. Van life as modelled here draws 4,685Wh a day; the DELTA 3 Max is 2,944Wh short of that and the Power 1000 is 3,815Wh short. Neither is close. This is a job for a larger station or a wired system, not a choice between these two.

Conclusion
August 9, 2026
Verdict: the DELTA 3 Max, on Power Score margin
The DELTA 3 Max holds 2,048Wh and the Power 1000 holds 1,024Wh, and at $899 against $699 that second kilowatt-hour costs $200, or about 15 cents a watt-hour. Both units are rated for 4,000 cycles and both carry a five-year warranty, so the cheaper energy isn't bought back later in a shorter life. The DJI has one genuine advantage and it's not a small one: 28.7 lbs against 50.7 lbs is a different object to move, and reviewers rate it among the quietest stations in its classB1. But three of the six scenarios on this page go to the EcoFlow on capacity alone, and the one the DJI takes outright is a CPAP night that either unit sleeps through without noticing. If the unit spends most of its life sitting still, buy the DELTA 3 Max.

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 Max rates 4.3/5 (60th percentile of 26 Large-class units), and Power 1000 rates 3.8/5 (31st percentile of 27 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.
Fixed at 1,024Wh, and that's mostly fine
The Power 1000 is sealed and the DELTA 3 Max accepts expansion batteries. That's a real advantage, and a narrower one than it sounds. Sealed at 1,024Wh isn't a feature withheld from a one-kilowatt-hour station; it's what one looks like finished. Expansion only pays if you already believe 2,048Wh won't be enough, and if you believe that, price the expansion battery now rather than counting an empty socket as capacity you own.
UPS Switchover: 10ms vs 20ms
The DELTA 3 Max is rated to switch to battery in 10ms and the Power 1000 in 20ms. Both are rated figures rather than measurements, and the difference between them is one hundredth of a second. If you're running a desktop, a router or a NAS off either of these, the switchover spec is not what will decide it. How long the battery lasts once the switch has happened is.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The Power 1000's figure is a maximum rather than a guarantee — it depends on buying from DJI's own store, which is where the full five years is advertised. Worth saying because the per-dollar framing can suggest otherwise: the Power 1000 works out at 7.2 years of cover per $1,000 spent against the DELTA 3 Max's 5.6, but that spread is the price gap, not the terms.

Analyst note
The Power 1000 is cheaper to buy, but the DELTA 3 Max is cheaper to own. At $0.11/kWh over its lifetime vs $0.17/kWh, the DELTA 3 Max'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
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/chat support (1-800-368-8604). Experiences are polarized — many report hassle-free prepaid-label replacements, but others report long waits and refurbished units sent for new claims. Pro tip: buying from Costco or Amazon gives you a stronger return safety net.
Community
Largest community in the space — Reddit r/Ecoflow_community (~31K members), multiple Facebook groups, and an official community forum
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
X-Stream fast charging is the genuine differentiator, and the catalogue behind it is the deepest in portable power. The practical version of that: expansion batteries and panels for this specific unit exist, are current, and are supported, which isn't true of every brand selling a 2kWh station.
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
DJI entered power stations in 2024 and the current line runs to four models: Power 500, Power 1000 V2, Power 1000 Mini and Power 2000. Note what isn't on that list. The unit priced on this page is the base Power 1000, and DJI's own current lineup names the V2 instead, so confirm the model number on whatever listing you're looking at 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
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
Quiet is the line's signature: 23 to 30dB published across every model, at the quiet end of the category. Behind it sit 700-plus battery patents from the drone business, LFP cells rated past 4,000 cycles, and SDC ports that fast-charge DJI flight batteries. The industrial design and build quality run a step ahead of the price.
Worth knowing
Two things to budget for. There's no built-in solar charge controller, so solar needs a separate DJI adapter rather than a generic cable. And the SDC ports that make this unit attractive are proprietary, so that advantage mostly accrues to people already inside the DJI ecosystem. Battery expansion exists on the Power 2000 and the Power 1000 V2, but not on this one, so what you buy is what you have.
Analyst note
EcoFlow and DJI are close competitors. Both have established support channels and growing ecosystems. Compare their specific warranty terms and community size for your peace of mind.
Growth path
DELTA 3 Max
EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 2,048Wh.
Accepts up to 1,000W of solar. Enough for a serious multi-panel array.
Generous port selection supports complex multi-device setups.
Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.
Power 1000
FIXED CAPACITYFixed at 1,024Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 800W of solar. Suitable for a 1-2 panel setup.
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
The Power 1000 is sealed at 1,024Wh, which is fine if that covers you. The DELTA 3 Max starts at 2,048Wh and can grow beyond it with EcoFlow expansion batteries — real headroom the Power 1000 doesn't have if your needs climb toward partial-home backup.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 Max
The record on the DELTA 3 Max is review-desk rather than long-haul owner. No large forum threads surfaced this pass, so what exists comes from people who had the unit for weeks rather than yearsA3A4. What they found is reassuring: measured capacity held steady between one-month and three-month tests, and the unit came through truck-bed transport, storage in a roughly 105F garage, and operation near freezing at about 34F without troubleA3. One desk scored it 8.5 out of 10, calling the mix of fast recharge and LFP longevity one of the better value propositions in the 2kWh classA4.
On noise the reported experience runs ahead of the 30dBA spec: essentially silent at conversational distance under moderate load, with fans that rise under heavy draw but stay quieter than most of the 2kWh fieldA1. The app is the other thing reviewers keep returning to, specifically the quiet mode and the custom charge-speed limitA1A2. Those are the two settings that matter if this lives in a room you sleep in.
“Whisper-quiet under moderate load — essentially silent at conversational distance; the app adds a low-power quiet mode and a custom charge-speed limit if fan noise bothers you. Fans rise under heavy load but stay quieter than most competitors in the 2kWh class.”

DJI Power 1000
The Power 1000's standout in the field is how little you hear it. Reviewers place it among the quietest stations in its class, with sound only becoming noticeable past 1,500W and even then a soft whoosh rather than a whineB1, and the fan barely registers during full-speed AC chargingB3. That charging is quick: about 70 minutes empty to full, roughly 50 minutes to 80%B3.
It also takes more than its rating promises. One test held it at 2,400W, above the 2,200W it's rated for, for twenty minutes with no shutdownB2. And the use it gets is the use it's built for: a week-long camping trip running a 45W compressor fridge alongside phones, laptops and LED lights, plus a following among drone pilots who top up flight batteries while everything else stays onB4. As with the EcoFlow, this is review-desk evidence and directional rather than a long owner recordB1B4.
“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.”

“AC charging takes about 70 minutes from 0% to 100% (about 50 minutes to 80%), and during full-speed charging the fan barely makes a sound.”

“Over a week-long camping trip it powered a 45W compressor fridge, phones, laptops, and LED lights; it's also a favorite of drone pilots for fast-charging DJI batteries while running other devices.”

Who Should Buy Which
Buy the DELTA 3 Max if you…
- →You're buying because the power goes out. The DELTA 3 Max is the only one of these two that covers the 1,645Wh eight-hour blackout the table models, and while it's doing that job it sits on a floor, where 50.7 lbs costs you nothing.
- →You camp with a fridge and the rest of the list. Weekend Camping asks 2,100Wh and the DELTA 3 Max is 359Wh short on the derated basis, close enough that dropping one item finishes the weekend. The Power 1000 isn't in that conversation.
- →You already suspect you'll want more later. It accepts EcoFlow expansion batteries; the DJI can't, at any price.
Buy the Power 1000 if you…
- →You carry it. Drone pilots do, and it's a favourite for precisely that reason, topping up flight batteries while the laptop stays onB4. 28.7 lbs is the spec that earns the $699.
- →It's running a CPAP and not much else. That night draws 320Wh and leaves the Power 1000 with 550Wh of derated usable still in the tank, so the extra $200 would be buying capacity the mask will never reach.
- →Your loads are tailgate-sized. The 670Wh that scenario models leaves the DJI 200Wh of derated usable spare, and you're the one walking it across a parking lot.

If neither fits
You're living in the van. That scenario models 4,685Wh a day and the bigger of these two is still 2,944Wh short of it, so this is the wrong page: go up a class to a station built for daily house-scale draw, or wire a proper fixed system. And at the other end, if the job is phones, a laptop and some lights, both of these are more battery than you will ever discharge in a sitting. DJI's own Power 500 sits in the same lineup and is closer to the class you actually want.
The Bottom Line
The DELTA 3 Max at $899 is the buy. The second 1,024Wh it gives you over the Power 1000 costs $200, the gap between $899 and $699, and works out near 15 cents a watt-hour. The same 4,000-cycle rating and the same five-year warranty cover both units, so no bill arrives later for that cheaper energy. Three of the six scenarios here go to the EcoFlow purely on how much it holds.
The DJI isn't the loser so much as the smaller entry. It's genuinely quiet, it held above its rated output under testB2, and at 28.7 lbs it's a box you'll actually move. If you carry your power station more often than you lean on it, buy it, and confirm you're getting the base Power 1000 rather than the V2. Everyone else: take the heavier box and stop thinking about it.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DJI Power 1000 the same as the Power 1000 V2?
No, and it's worth confirming before you buy. Our brand record lists DJI's current power line as the Power 500, Power 1000 V2, Power 1000 Mini and Power 2000, and notes separately that battery expansion is available on the Power 2000 and the Power 1000 V2 but not on the earlier Power 1000 or Power 500. The specs quoted here (1,024Wh, 2,200W, 28.7 lbs, $699) are the base unit's. If a listing doesn't state which one it is, ask before you pay.
Is the EcoFlow DELTA 3 Max worth the extra money over the DJI Power 1000?
Yes, unless weight decides it for you. $899 against $699 is $200 more for 2,048Wh against 1,024Wh, with the same 4,000-cycle rating and the same five-year warranty on both sides. Doubling the battery for that is the best value on this page. The only good reason to decline is that the DELTA 3 Max weighs 50.7 lbs and the DJI weighs 28.7.
Can the DJI Power 1000 run a refrigerator?
Yes. It's rated 2,200W continuous with 4,400W of surge, double its rating, which covers the startup spike a compressor pulls. In the field it ran a 45W compressor fridge across a week-long camping trip alongside phones, laptops and lights. The constraint isn't whether it starts the fridge, it's the 1,024Wh you're running it from.
Which one is quieter?
Both are quiet, and the DJI is quieter on the published figure: 23dBA against the DELTA 3 Max's 30dBA. Treat those as single published ratings rather than measurements at the load you'll actually run. Reviewers describe the DJI as near-silent until you push past 1,500W, and the DELTA 3 Max as essentially silent at conversational distance under moderate load, with a quiet mode and a charge-speed limit in the app if the fan ever bothers you. Next to a bed, the DJI is the safer bet on paper, but neither is a fan you'd lie awake listening to.
Which should I buy for a home blackout?
The DELTA 3 Max. It's the only one of the two that covers the eight-hour blackout the table models, and it finishes with 96Wh of derated usable left, which is a pass rather than a cushion. The Power 1000 comes up 775Wh short of the same load. Switchover is rated at 10ms against 20ms, both stated figures rather than measurements, and that isn't what decides this.
