Head-to-head test
EcoFlow DELTA 3 Max Plus vs DJI Power 1000
DJI has replaced the Power 1000 with the Power 1000 V2, so only one unit on this page is still the one its maker sells, and the question behind it is whether you need a battery that finishes an eight-hour outage or a 28.7-pound box that covers an evening.

Spec deltas
DJI has superseded the Power 1000 with the Power 1000 V2, which settles most of this page before the specs get a word in. The original may still turn up in retailer stock, and it is not broken or abandoned if you find one, but it is no longer the unit DJI sells under that name. That leaves one of these two with a maker still standing behind it: the EcoFlow DELTA 3 Max Plus.
The specs agree, which makes the recommendation an easy one. Take the flat 15% conversion allowance this site applies to every unit and the DELTA 3 Max Plus has 1,741Wh of usable energy against the Power 1000's 870Wh. That is the difference between the eight-hour blackout list finishing and the same list ending while it is still dark.
What the Power 1000 has is genuine and small. At 28.7 lbs against 50.7 it is the one you carry rather than stage, and its near-silent running under normal loads is not a marketing lineB1. If weight is the spec that decides your purchase, the honest move is to look at what DJI sells now instead of chasing the revision this page is about.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
The Power 1000 is sealed at 1,024Wh, and DJI put battery expansion on later models in the line rather than this one, so undersizing it leaves you buying a second box. The DELTA 3 Max Plus starts at twice the capacity and still has an expansion port behind that. Cycle life is the spec buyers worry about and capacity is the one that actually runs out.
Both units are rated for 4,000 cycles2,048Wh of capacity against 1,024Wh8,192kWh of total lifetime throughput against 4,096kWh
Why it mattersIf you are buying a 4,000-cycle unit you intend to keep for a decade, size it for the loads you will have in year five, not the ones you have this weekend.
Outages do not come in tidy single nights, and the wall socket is the thing that is missing, so the refill has to come from the sun: 1,000W of solar input against 800W. That is a bit over two hours of strong sun to put 2,048Wh back against a bit over an hour for 1,024Wh, except that DJI's record carries no built-in solar charge controller, so panels reach the Power 1000 through a separate proprietary adapter you have to own first.
The 8-hour blackout list needs 1,645WhThe DELTA 3 Max Plus has 1,741Wh usable and clears it with 96Wh leftThe Power 1000 has 870Wh usable and finishes 775Wh short
Why it mattersIf your reason for buying is a grid that goes down for more than one evening, buy the bigger battery and the solar input that plugs straight in.
continuous output
That simultaneity costs 22 lbs. At 50.7 lbs the DELTA comes out of the car once and lives where you put it; at 28.7 lbs the Power 1000 goes in and out of a trunk as often as you like. On the one scenario both units clear outright, a 670Wh tailgate where the DELTA uses 38% of its usable energy and the DJI 77%, the extra sockets and watts do nothing at all and the 22 lbs do.
3,000W continuous and 6,000W surge against 2,200W and 4,400WSix AC outlets against two50.7 lbs against 28.7 lbs
Why it mattersPay the weight if your worst night is a whole-house evening; skip it if your habit is a cooler, a speaker and some lights in a parking lot.
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, or 1,741Wh against 870Wh usable, is the gap that decides which nights each unit finishes.
continuous output
Twice the battery sounds like a bragging spec until you put it against a list. After the flat 15% conversion allowance, the DELTA 3 Max Plus has 1,741Wh to spend and the Power 1000 has 870Wh, and the eight-hour blackout list wants 1,645Wh of that. One unit gets you to the point where the lights come back on. The other gets you most of the way to bedtime.
The remote workday is where the smaller unit gets unlucky: 910Wh of load against 870Wh usable. Its nameplate 1,024Wh clears that list outright, and the derate is what pushes it under by 40Wh, which is one small appliance's worth across a whole day. Trim that and it finishes. What it tells you is that the Power 1000 is not undersized so much as exactly sized, with nothing at all behind it.
Your Life, Your Pick
Selected because: Where that gap turns into evenings: one unit covers the 1,645Wh blackout list, the other stops 775Wh short of it.
Two of the six loads are out of reach for both units, and they are worth reading before the ones somebody wins. A 2,100Wh camping weekend leaves the DELTA 3 Max Plus 359Wh short and the Power 1000 1,230Wh short; van life at 4,685Wh is not close for either. Neither of these is the answer to full-time off-grid living, and a page that pretends otherwise is selling.
The row the Power 1000 takes is the CPAP night, and it takes it on the one thing this data cannot settle. A CPAP is about 40W, so 320Wh covers eight hours and both units have that several times over. What is left is which box you want next to your pillow, and the lighter one gets the benefit of the doubt on published quiet ratings that the two makers did not measure the same way.
Brand Trust
Selected because: One of these two has already been superseded by its maker, which is a brand fact before it is a spec fact.
DJI has been making power stations since 2024 and has already replaced this one. That is the brand story in a sentence: five models in the line so far, with the Power 1000 sitting behind the Power 1000 V2, which is why a listing that says Power 1000 is worth checking twice before you click. The deep hardware track record DJI carried over from drones is real, and so is the thin power-station one underneath it.
EcoFlow's case is the opposite shape, and not uniformly flattering. It has the deepest catalogue in the category and the largest community around it, plus a support experience that splits between prepaid replacement labels and long waits for refurbished units. Two things are worth knowing before you spend: EcoFlow floated subscription paywalls for advanced app features in early 2025 before pausing the plan, and it does not offer parts or service once the warranty lapses. Register the unit and buy from a retailer with a return window.
What the Specs Don't Tell You
Selected because: A sealed 1,024Wh ceiling, two UPS figures that are ratings rather than measurements, and matching five-year terms.
The expansion card is the one to sit with. The Power 1000 is sealed at 1,024Wh, so what you buy is the ceiling, and the DELTA 3 Max Plus does not merely have the port: it starts at 2,048Wh, which means expansion is the step after the step the DJI cannot take. Expandability only counts when the base it is bolted to is the bigger one to begin with, and here it is.
The UPS numbers deserve less weight than they will get. A rating of no worse than 10ms against no worse than 20ms is two ceilings the makers published, not two stopwatch results, and both sit inside what a router or a modem cares about. If a desktop with unsaved work is the thing being protected, the tighter class is the safer bet, but treat it as a class.
Portability & Form Factor
Selected because: 28.7 lbs against 50.7 is the Power 1000's clearest win, and the one reason to go look at what DJI sells now.
weight
Fifty pounds is not a number, it is a decision about where the unit lives. At 50.7 lbs the DELTA 3 Max Plus is a two-hands, bent-knees lift that comes out of the car once per trip; at 28.7 lbs the Power 1000 goes up a flight of stairs without a plan. Campers should also know that the DJI's record carries no 12V car socket, so a 12V fridge runs through the inverter rather than straight off DC, while the DELTA has one.
This is the single axis where the retired unit wins clean. If weight is what decides it for you, the right next click is DJI's current model rather than this one.

Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Neither unit finishes this one. The weekend list wants 2,100Wh, and the DELTA 3 Max Plus is 359Wh short of it while the Power 1000 is 1,230Wh short, about 83% of the weekend covered against about 41%. In practice both need a shorter list or sun, and both take panels, with the DELTA taking more of them. Plan the recharge into the trip and the DELTA gets you there; plan nothing and neither does.

8-Hour Blackout
Keep the essentials running through a night without power
DELTA 3 Max Plus
The list here comes to 1,645Wh, and the DELTA 3 Max Plus covers it with 96Wh left of its 1,741Wh usable, which is a finish rather than a cushion. The Power 1000 has 870Wh to work with and stops 775Wh short, a bit past half the night. If your outages tend to arrive in pairs, plan the refill before you plan the evening.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP draws about 40W, so eight hours of it is 320Wh: 18% of the DELTA 3 Max Plus's usable energy and 37% of the Power 1000's. Capacity has nothing to decide here. The row goes to the Power 1000 on the quieter published rating, and the tiebreak worth trusting is plainer than that: at 28.7 lbs it is the one that ends up in the bedroom at all. Each maker measures noise its own way, so check whichever one you buy by ear before it sleeps beside you.

DELTA 3 Max Plus
The Power 1000 comes up just short — it needs 910Wh and has 870Wh usable, a 40Wh gap (its nameplate 1,024Wh actually clears this — the flat 15% conversion allowance is what tips it under). Trim that much — one small appliance's worth across the day — and it finishes. The DELTA 3 Max Plus covers it outright with 831Wh to spare.

DELTA 3 Max Plus
Both handle game day; the DELTA 3 Max Plus keeps more in reserve (38% 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 50.7 lbs for the DELTA 3 Max Plus, from the trunk to the setup spot.

Conclusion
September 19, 2026
Verdict: the DELTA 3 Max Plus, on Power Score margin
Buy the DELTA 3 Max Plus. It is the only one of these two its maker is still selling: DJI superseded the Power 1000 with the Power 1000 V2, and while retailer stock of the original may still turn up, the older revision is not what DJI puts behind that name any more. The spec case runs the same direction for anything grid-shaped. At $1,199 the DELTA carries 2,048Wh against 1,024Wh, pushes 3,000W continuous against 2,200W, gives you six AC outlets against two, and has an expansion port behind a rival that is sealed for life. The Power 1000's wins are real and narrow, 28.7 lbs against 50.7 and a record of running near-silent under normal loadsB1, which makes it a good unit to keep if you own one rather than a unit to go hunting for.

Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
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 Plus rates 4.3/5 (56th percentile of 26 Large-class units), and Power 1000 rates 4.3/5 (58th 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.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The DELTA 3 Max Plus is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The Power 1000 is rated ≤20ms — 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 Conditions
Both records carry five years, so cover is not the tiebreaker here, but the two fives are not quite the same shape. DJI's is a maximum that depends on buying from DJI's own store, which is the store now stocking the V2 rather than this revision. EcoFlow's five years stands as recorded, with the caveat that EcoFlow sells no parts or service once it lapses. Per-dollar framings of warranty cover mean little when only one of the two units is still being sold, so read the terms instead: register the unit, buy through a channel with a return path, and keep the receipt somewhere you will still find it in year four.

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 3 Max Plus 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 3 Max Plus delivers about 8,192 kWh and the Power 1000 about 4,096 kWh. 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.

Unique strength
The deepest catalogue in portable power, from RIVER 3 up through DELTA Pro, plus panels and smart home panels, so the expansion port on this unit opens onto something real. X-Stream fast charging is the other standing advantage.
Worth knowing
EcoFlow floated subscription paywalls for advanced app features in early 2025 and paused the plan after community pushback, and it offers no parts or service out of warranty. Neither should stop you buying. Both are reasons to register the unit and keep the receipt.
DJI
Ecosystem
Five power stations in two years, and this one has already been superseded by the Power 1000 V2. That is the practical warning: a listing that says Power 1000 may be either revision, so check what 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
There is no DJI power-station community yet. Questions land in r/dji, a quarter-million strong and almost entirely about drones, which is a fine room for SDC charging questions and a thin one for blackout advice.
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
No built-in solar charge controller: panels reach the unit through a separate proprietary DJI adapter, so the 800W solar input has a part attached to it. The SDC ports are proprietary too, a genuine perk if you already fly DJI and irrelevant if you do not. Battery expansion arrived on later models in the line, not on this one.
Analyst note
The difference that matters is not catalogue size, it is that one of these brands still sells the unit on this page. DJI's hardware reputation arrived ready-made from the drone business and the build quality shows it; what it does not have yet is a long power-station track record, and its answer to needing more has so far been a new revision rather than a port on the side of the box. EcoFlow's answer is a catalogue you can grow into, with an app it once tried to charge for.

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 3 Max Plus: it starts at 2,048Wh 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 3 Max Plus.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 Max Plus
Coverage of the DELTA 3 Max Plus is review-based rather than long-term, since the unit is new enough that owner histories are still accumulatingA0. What exists is consistent: 80% in about 50 minutes and full in roughly 70 on ACA3, the 3,000W and 6,000W step over the plain DELTA 3 Max treated as a real upgrade rather than a badge changeA1, and quiet running under typical loads, with the fans only spinning up briefly at shutdownA2.
On growth, reviewers describe the path from 2kWh up to 10kWh via Smart Extra Batteries as polished and effortlessA4, which matters mostly as evidence that the expansion port is not theoretical.
“Bumps output to 3,000W continuous with a 6,000W surge — a significant upgrade over the DELTA 3 Max's 2,400W and 4,800W surge.”

DJI Power 1000
The Power 1000's record is closed now, and it reads well. Noise is the standout: near-silent under normal loads, with sound only becoming noticeable past 1,500W and then as a soft whoosh rather than a whineB1. One bench ran it at 2,400W, above its 2,200W rating, for twenty minutes with no shutdown and no fan dramaB2, and AC charging lands at about 70 minutes to full, 50 to 80%B3.
A week of camping on a 45W compressor fridge plus phones, laptops and lights is the trip it keeps turning up in, alongside drone pilots charging batteries between flightsB4. Two caveats: this is review coverage rather than years of ownership, and it describes the base Power 1000 rather than the revision that replaced itB0.
“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.”

Who Should Buy Which
Buy the DELTA 3 Max Plus if you…
- →The blackout buyer with a fridge, a router and a pile of phones to keep alive: 1,741Wh usable clears the eight-hour list with something left, and 3,000W means you are not choosing between the microwave and the kettle.
- →Anyone whose load list is growing. Six AC outlets, a 12V car socket and an expansion port make this the unit you add to rather than the unit you replace.
- →The workshop user who starts motors. A 6,000W surge over a 3,000W continuous rating is twice the headroom, and surge is what decides whether a tool starts or trips.
Buy the Power 1000 if you…
- →If you already own one, keep it. It is a 4,000-cycle pack with a five-year term on the record, and nothing about DJI shipping a V2 makes the box on your shelf worse.
- →If you are set on DJI, whether for SDC drone charging or because 28.7 lbs is the spec that decides it, the model to look at is the Power 1000 V2 rather than this one.
- →If a retailer is clearing the original at a real discount and your loads genuinely live under 870Wh usable, it is not a mistake. Check which revision is actually in the box first, because the listings do not always say, and at anything short of a real discount the V2 is the one to buy.
If neither fits
Skip both if your day looks like the van-life list. At 4,685Wh even the bigger unit finishes 2,944Wh short, and the answer there is a larger station or a wired 12V system, not a choice between these two. Skip both as well if a CPAP is the only reason you are shopping: 320Wh a night is 18% of the DELTA's usable capacity, and a station a fraction of this size does that job without asking you to lift 50.7 lbs.
The Bottom Line
Take the DELTA 3 Max Plus. It is the only one of the two its maker still sells, and the availability answer and the spec answer point the same way: 1,741Wh usable against 870Wh is the difference between an eight-hour outage you sleep through and one that ends while it is still dark.
The Power 1000 was a good box and still is one, quiet and steady above its rating under loadB1B2, and at 28.7 lbs it goes places the DELTA will not. If that is the unit you want, DJI's answer is the Power 1000 V2. If it is not, you already know which one to put in the cart.
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 retired the original in August 2026. Retailer stock of the older revision may still turn up, and it is not an abandoned unit if you find one, but it is no longer what DJI sells under that name. Because listings do not always spell out the revision, check which one actually ships before you buy.
Which one gets me through an eight-hour blackout?
The DELTA 3 Max Plus. That scenario's list adds up to 1,645Wh, and after the flat 15% conversion allowance the DELTA has 1,741Wh to spend against the Power 1000's 870Wh, so the DJI stops 775Wh short, a bit past half the night. The DELTA finishes with 96Wh left, which is coverage rather than comfort: for two nights in a row you are refilling from solar in between.
Does the DJI Power 1000 charge from solar panels?
Yes, rated to 800W, but not straight out of the box. DJI's record carries no built-in solar charge controller, so panels connect through a separate proprietary adapter you have to buy. The DELTA 3 Max Plus takes up to 1,000W of solar directly. If panels are part of your plan, count that adapter as part of what the DJI costs you.
Is the DJI Power 1000 quiet enough to sleep next to?
Probably, and so is the DELTA 3 Max Plus, though not for the reason the spec sheets imply. Each maker publishes its noise rating its own way, so the two figures are not comparable and neither describes a 40W CPAP draw. What we have is steady description of the DJI as near-silent under normal loads and only audible past 1,500W, and of the DELTA as quiet under typical loads with a brief fan spin at shutdown. At CPAP wattage both sit far below where either fan has a reason to work.
Can I add a second battery to the DJI Power 1000?
No. It is sealed at 1,024Wh, and DJI added battery expansion on later models in the line rather than this one. If your needs might climb, that is the argument for the DELTA 3 Max Plus, which starts at 2,048Wh and takes EcoFlow expansion batteries on top of that.
