Head-to-head test
EcoFlow DELTA 3 1000 Air vs DJI Power 1000
Both have been replaced. EcoFlow has discontinued the DELTA 3 1000 Air and DJI has replaced the Power 1000 with the Power 1000 V2. As machines, the Air was a light desk UPS and the DJI a general-purpose box with more than four times the inverter.

Spec deltas
Both of these have left their makers' ranges. EcoFlow discontinued the DELTA 3 1000 Air, and the DELTA 3 Classic is the replacement we'd point to. DJI swapped the Power 1000 for the Power 1000 V2. This page shows neither a price, so read it as a record of what each box does, for anyone who owns one or spots one on a clearance shelf.
They hold almost the same energy. What they do with it is very different. The Air's inverter, the part that makes household AC, runs 500W, and one review says that rules out a space heater or a hair dryerA3. The DJI's runs 2,200W.
The Air is a desk appliance. It's rated to switch to battery in 10ms or less when the power drops, and a review frames it as a unit for keeping a computer, monitor and router aliveA2. If the router and laptop at my cabin were the whole job, it would do that job at 22 lb. The DJI covers the rest, from a compressor fridge on a week of campingB4 to a laptop on its 140W USB-C port.
What the Numbers Reveal
Each conclusion stated first β the numbers behind it on one line, the full analysis below.
continuous output
A hair dryer or a space heater asks for more than the Air can give at any charge level. The DJI's rating covers those, and one reviewer held it above that rating for 20 minutesB2.
the 1000 Air's inverter tops out at 500W continuous with a 1,000W surgethe Power 1000 runs 2,200W continuous with a 4,400W surge, 4.4 times both figuresone review notes the 1000 Air's 500W output won't run a space heater or hair dryer, calling it built for low-to-moderate draw devicesA3
Why it mattersIf a heater or a hair dryer is on your list, the Air was never the right box for it.
That matters most to a desktop, because the fussiest PC power supplies sit near the slower line. The Air's 18W USB-C port pulls the other way at the same desk. A laptop charges slowly on 18W, and under load it may not charge at all.
the 1000 Air is rated to switch to battery in 10ms or less, the Power 1000 in 20ms or lessthe 1000 Air's fastest USB-C port outputs 18W against the Power 1000's 140W
Why it mattersThe Air suited a tower PC on its single AC outlet. A laptop setup was better served by the DJI's 140W port.
The specific dimensions that decide these two units β everything else is a tie.
What the Specs Don't Tell You
Selected because: USB-C speed, UPS switchover, and cycle life with warranty are the specs that separate these units.
rated cycles
The DJI's USB-C port charges a laptop at close to full speed, where the Air's 18W port struggles. Its battery is rated for a third more cycles, with up to five years of cover to two. The Air's sealed 960Wh can't be expanded, though with both units replaced that is a question for owners only.
Where the Air leads is switchover, the spec a desktop cares about. It only helps inside the light loads the Air could power in the first place.
Lifetime Value
Selected because: Lifetime energy and warranty both favour the DJI; neither unit carries a price, so the section argues from ratings.
Neither unit carries a price here, so this section argues from ratings alone. The DJI's battery is rated to deliver about 4,096 kWh over its life to the Air's 2,880. At a cycle a day that's about eleven years to eight.
If either one already lived at my cabin, I'd keep using it. When a cycle rating runs out, the battery keeps working with less capacity. Buying secondhand, ask for the cycle count and the purchase date first, because a two-year warranty doesn't stretch far.
Brand Trust
Selected because: EcoFlow's deep ecosystem against DJI's newer, quieter build, with both units now replaced by successors.
EcoFlow has the far deeper bench: the largest lineup in portable power, the largest community around it and an app that rates well on both stores. Support experiences are split, so buying through a big retailer adds a safety net.
DJI came to power stations in 2024 and leans on the repair network from its drone business. Reviews of this first-generation unit call it quiet and dependableB1B2. The catch is its own connectors: solar goes through a DJI adapter, and the SDC ports fast-charge DJI gear.
Portability & Form Factor
Selected because: The Air is the lighter box; the better-documented quiet belongs to the DJI.
weight
The Air is 22 lb and the DJI 28.7. Almost seven pounds is the difference between carrying it one-handed to the car and setting it down halfway.
The noise question stays open on paper, because each maker rates its own fan its own way. What the reviews document is the DJI staying nearly silent under normal loadsB1. If the box will sit by a bed, that's the account I'd go on.
Strengths & trade-offs

DJI Power 1000
Strengths
- +Larger battery capacity
- +Higher AC output
- +Longer warranty
- +Faster solar charging
- +Rated for 4,000 charge cycles β much longer battery lifespan
Trade-offs
- βNo major technical downsides compared to rival.

Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Neither unit covers this scenario's 2,100Wh: the DELTA 3 1000 Air comes up 1,284Wh short (about 39% covered), the Power 1000 1,230Wh (41%). Treat this as partial cover β enough for the essentials in it, not the whole list.

Neither unit
Neither covers the full 1,645Wh basket. Each runs out about halfway through the night. Covering all of it is a job for the 2kWh class.

LOADΒ Β Fridge 150WΓ8h Β· Router + Modem 20WΓ8h Β· LED Lights (4 bulbs) 40WΓ6h Β· Phone Charger 15WΓ3h
SCN-03 Β· 8 hours Β· needs 320Wh
CPAP Overnight
Sleep therapy without interruption β the #1 medical use case
Either unit
A 320Wh night uses well under half of either battery. Each maker rates its own fan noise its own way, so the spec sheets can't say which is quieter by the bed. For a new CPAP backup, look at their successors.
Battery budget usedlower = more headroom
LOADΒ Β CPAP Machine 40WΓ8h
SCN-04 Β· 8 hours Β· needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
Neither unit
The DJI lands within about 5% of a 910Wh workday, close enough that one trimmed device gets it there. The Air falls further short, and its 18W USB-C port is slow for a laptop anyway.
Battery budget usedlower = more headroom

SCN-05 Β· 4 hours Β· needs 670Wh
Tailgate Party
Game day power for the crew
Either unit
Both carry a 670Wh game day. The Air finishes with less in reserve, and its 500W inverter keeps you to phones, lights and a speaker. Anything bigger wants the DJI.

Conclusion
October 25, 2026
Verdict: evenly matched
Both have been replaced, so this page has no pick to buy. If you are shopping, put the DELTA 3 Classic beside the Power 1000 V2. Judged as the machines they were, the DJI was the more capable box, with more than four times the inverter, a far faster USB-C port and a longer warranty. The Air was the narrower tool, built to keep a desk running, with the quicker switchover rating.

See the full weight table and data sourcing on our methodology page βClass ranking (the star rating)
Each unit's star score is a category ranking, not customer reviews β 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 5β . Here, DELTA 3 1000 Air rates 5.0/5 (99th percentile of 20 Compact-class units), and Power 1000 rates 4.3/5 (58th percentile of 27 Everyday-class units).
How the class ranking is computed βTest Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
18 watts charges a phone. 140 charges a laptop.
The Air's fastest USB-C port tops out at 18W. Most USB-C laptops want at least 60W for full-speed charging, and at 18W one may barely charge under load. The DJI's 140W port charges a modern laptop at close to its wall-adapter speed.
DELTA 3 1000 Air: Fixed Capacity
The DELTA 3 1000 Air is sealed at 960Wh, and that is the ceiling. With both units replaced, expansion isn't a buying question between these two.
The smaller box switches faster
The Air is rated to switch to battery in 10ms or less, quick enough on paper for a desktop and router to ride through. The DJI is rated at 20ms or less, which suits routers and most electronics, though the fussiest PC power supplies sit right at that line. Both figures are the makers' own ratings.
Warranty: 5 Years vs 2
The Power 1000 is covered for 5 years against the DELTA 3 1000 Air's 2 years. The Power 1000's figure is a maximum rather than a guarantee β it depends on buying from DJI's own store, which is where the full five years is advertised. An underrated factor if you're keeping this unit for years.
3,000 cycles against 4,000
The DJI is rated for a third more full charges, 4,000 to the Air's 3,000, and backs it with up to five years of cover against two. Used daily, that's about eleven years against eight. When either reaches its rating, the battery keeps going with less capacity.

Analyst note
Neither is sold new any more, so there is no price left to work a cost per kWh from, and what either costs you now depends on the used market. The hardware comparison still holds: over its rated life the DELTA 3 1000 Air delivers about 2,880 kWh and the Power 1000 about 4,096 kWh.

Worth knowing
EcoFlow no longer sells the 1000 Air. It offers no parts or service out of warranty.
DJI
Ecosystem
DJI entered power stations in 2024, leaning on its drone and camera reputation.
Support
Backed by DJI's global repair network from the drone business, with little power-station history to judge it by yet.
Community
No dedicated power-station community yet. What discussion exists lives inside the much larger r/dji, mostly among drone owners.
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 running across most of the range by DJI's own best-case figures, and SDC ports that fast-charge DJI drone batteries directly.
Worth knowing
There's no built-in solar charge controller, so solar needs a separate DJI adapter. The on-device screen is reported to be more dependable than the companion app.
Analyst note
EcoFlow is the deeper ecosystem and community. DJI brings build quality, quiet running and a support network it didn't have to build from scratch. With both models replaced, the brand question now sits between the DELTA 3 Classic and the Power 1000 V2.

- βOwners with heavier loads: 2,200W continuous and a 4,400W surge start what the Air can't.
- βLaptop users: the 140W USB-C port charges at close to full speed, where the Air's 18W port struggles.
- βAnyone keeping it for years: it's rated for 4,000 cycles, with up to five years of cover when bought from DJI.
If neither fits
Both have been replaced, so a new buyer should start with the EcoFlow DELTA 3 Classic and the DJI Power 1000 V2. If your list looks like our 8-hour blackout at about 1,645Wh, or a weekend of camping at about 2,100Wh, neither of these boxes covers it alone. Look at a bigger station.
The Bottom Line
Both boxes have been replaced, so this page has no pick for a shopper. As machines, the Power 1000 was the broader one. The Air was a desk UPS that switched faster and weighed less.
If you own one, use it for what it was built for. If you're buying, start with the DELTA 3 Classic and the Power 1000 V2.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
EcoFlow DELTA 3 1000 Air vs DJI Power 1000: which should I buy?
Neither, if you're buying new. Both have been replaced, so compare the EcoFlow DELTA 3 Classic with the DJI Power 1000 V2 instead. As machines, the Power 1000 was the more capable of the two, with a 2,200W inverter to the Air's 500W, more cycle life (4,000 against 3,000) and a longer warranty (up to 5 years against 2). The Air suited light electronics, where its switchover rating of 10ms or less was the faster.
Can the DELTA 3 1000 Air run a space heater or hair dryer?
No. A review of its 500W continuous inverter says it isn't built for those loads, calling it a unit for low-to-moderate draw devices. The Power 1000's 2,200W inverter clears that category of appliance.
Which power station is quieter, the 1000 Air or the Power 1000?
Reviews favour the Power 1000. One calls it one of the quietest stations in its class, with sound only becoming noticeable past 1,500W of load. The spec-sheet figures, 23dBA for the DJI and 39dBA for the EcoFlow, are each maker's own rating measured its own way, so they can't be compared directly.
Are the DELTA 3 1000 Air and DJI Power 1000 still sold?
Not as current models. EcoFlow has discontinued the DELTA 3 1000 Air, and the DELTA 3 Classic is our recommended replacement. DJI has replaced the Power 1000 with the Power 1000 V2. Some retailer stock may linger, so check which model and revision a listing ships.
Which has the better warranty and battery life?
The DJI Power 1000. It's rated for 4,000 charge cycles against the 1000 Air's 3,000, and carries up to a 5-year warranty when bought from DJI's own store, against 2 years on the Air.
