EcoFlow DELTA 3 1000 Air vs BLUETTI AC180
These are the same size battery with very different taps: 500W continuous out of the DELTA 3 1000 Air against 1,800W out of the AC180, so this is decided by what you plug in, not by how long it runs.

EcoFlow has discontinued the DELTA 3 1000 Air — it has left EcoFlow's own store and our price tracking, though remaining retailer stock may linger. Our recommended replacement is the EcoFlow DELTA 3 Classic: the same 1kWh class, with an 1,800W inverter to the Air's 500W.

Spec deltas
The AC180 is the one to buy, and the battery has nothing to do with it. At 960Wh against 1,152Wh these are the same size class. The difference is the tap: 500W continuous out of the DELTA 3 1000 Air against 1,800W out of the AC180. Five hundred watts covers a laptop, two monitors, a router and a CPAP all night. It does not cover a kettle, a hair dryer or a space heaterA3.
EcoFlow has also stopped selling the AirA4. What is left is retailer stock, and the $309 we captured is a single spot reading with no price history behind it, so treat it as today's clearance number rather than what the unit costs. The closest current replacement in EcoFlow's own line is the DELTA 3 Classic, which puts an 1,800W inverter in the same one-kilowatt classA4. That is EcoFlow's verdict on a 500W ceiling, not ours.
The Air wins one thing outright, and it is the thing you feel: 22 lbs against 35.3 lbs. One is a single-hand lift out of a trunk, the other is a two-hands, knees-bent lift, and weight is the caveat that comes up most often in the AC180's coverageB2. If the unit lives under a desk and never moves, that difference is worth nothing. If it goes in and out of a car every Saturday, it may be the only spec on this page you ever notice.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
So the Air's laptop story runs through its AC outlet and the laptop's own brick, spending inverter overhead on a job the AC180 does straight from a 100W USB-C port. On a unit whose whole stated purpose is home-office power protectionA2, that is the port that should have been the headline.
DELTA 3 1000 Air: UPS switchover rated no worse than 10msDELTA 3 1000 Air: fastest USB-C port outputs 18WAC180: fastest USB-C port outputs 100WMost USB-C laptops need at least 60W for full-speed charging
Why it mattersIf your desk is a USB-C laptop, the AC180 replaces your charger. The Air only protects it.
continuous output
The Air's entire ceiling is 1,000W, and it clears the 400W our heaviest scenario asks for. Everything above that is a wall with nothing behind it, because the pack is fixed at 960Wh and nothing bolts on. The AC180 starts nearly three times the spike and sustains more than three times the load, which is the difference between a unit you plan loads around and a unit you plug things into.
DELTA 3 1000 Air: 500W continuous, 1,000W surgeAC180: 1,800W continuous, 2,700W surgeThe Air holds the better surge-to-continuous ratio, 2x against 1.5xThe heaviest startup in our scenario set is the 400W tailgate peak
Why it mattersIf you cannot write down every load in advance, the 500W ceiling will find you. Buy the AC180.
cost / lifetime kWh
That penny also rests on one unverified spot price, so it holds at $309 and nowhere else. Spread the money against coverage instead and the order flips: $309 over two warranty years is $155 a year, while $499 over five years, direct or registered, is $100.
Air $309 from a spot capture with no price history; AC180 $499 from a tracked baseline960Wh x 3,000 cycles = 2,880 lifetime kWh; 1,152Wh x 3,500 cycles = 4,032Cost per lifetime kWh: $0.11 for the Air, $0.12 for the AC180
Why it mattersNobody should pick the Air to save money over the long run. The only money argument for it is the sticker, on the day you find it.
That matters more for backup gear than for anything else you buy, because the failure you care about is the one you find in year four when the power goes out. The AC180's cells are rated past 3,500 cyclesB3 and its term runs to five years if you buy direct or register, so one purchase decision makes both promises at once.
EcoFlow no longer sells the DELTA 3 1000 AirA4The Air's warranty term is 2 yearsEcoFlow offers no parts or service out of warrantyAC180: rated 3,500-plus full cycles, covered up to 5 yearsB3
Why it mattersIf this is emergency equipment that will sit and wait, the years are part of the spec. Take the AC180 and register it the day it arrives.
The specific dimensions that decide these two units — everything else is a tie.
What the Specs Don't Tell You
Selected because: Output decides this page, not capacity: 500W continuous and 1,000W of surge on the Air against 1,800W and 2,700W on the AC180, plus an 18W USB-C port against 100W.
rated cycles
Three of the four cards here point at the Air, and one points back at our pick. The output card and the USB-C card are hard limits on a sealed unit, so neither is fixable later by firmware or by accessories. The warranty card is real but conditional on both sides, and it is the one you can act on at checkout.
The UPS card is the honest exception. The Air is rated no worse than 10ms where the AC180 is rated no worse than 20ms, and if the thing you are protecting is a desktop with unsaved work, that tighter class is a genuine point in the discontinued unit's favour. Both figures are published ceilings rather than stopwatch results, so read them as classes, not lab results.
Your Life, Your Pick
Selected because: Three of the six loads are too big for either unit, which leaves the two rows the AC180 takes on capacity and the one night both cover with hundreds of watt-hours spare.
Half this table says neither, and that is the most useful thing in it. The camping list, the eight-hour blackout and the van-life day all want more energy than either pack holds, and both units come back with a partial. The AC180's extra usable capacity, 979Wh against 816Wh, shortens every shortfall without closing one.
The row that separates them separates them by a hair. The 910Wh workday leaves the AC180 69Wh in hand and the Air 94Wh short, and the Air's nameplate 960Wh clears that load on paper: it is the flat 15% conversion allowance we apply to every unit that tips it under. Call it a day that ends tight rather than a hard fail, then decide how you feel about tight when it is your work machine plugged into it.
Lifetime Value
Selected because: The $190 between the Air's $309 and the AC180's $499 is why most people land here, and across a full service life that gap comes to one cent per kilowatt-hour.
cost / lifetime kWh
One cent per lifetime kilowatt-hour is the answer, and it is the wrong question. Both units have the same shape of value: LFP cells, thousands of cycles, and a price that works out to pennies of energy across a decade of weekends. What differs is what the cheaper one can do while it delivers those pennies.
The Air's price is also the softest number on this page. It is a single spot capture with no history behind it, on a unit EcoFlow has stopped sellingA4, and clearance prices move in both directions. The AC180's is a baseline we have tracked. If you are deciding on cost of ownership, decide on the figure you can still verify at checkout.
Portability & Form Factor
Selected because: 22 lbs against 35.3 lbs is the Air's one clear win, and the only difference on this page you feel with your hands.
weight
Thirteen pounds is the difference between one hand and two. The Air goes over a tailgate with a grocery bag in your other hand. The AC180 gets set down, then repositioned, then left where it landed.
It cuts the other way at the campsite, because the light unit is also the one that runs out first on every load big enough to matter. The weight is the tax the AC180 charges for being the unit that finishes the job.
Brand Trust
Selected because: One of these units is out of production on a two-year term; the other's five-year term depends on buying direct or registering it.
EcoFlow gets you US phone lines and prepaid return labels when a claim goes well, and BLUETTI gets you email and a timezone gap. That is the usual comparison and it is not the one that matters here. The Air is out of productionA4, EcoFlow offers no parts or service past the warranty, and that warranty is two years. There is a date after which the unit is yours alone to fix.
The AC180's five-year term has a condition worth meeting: buy direct from BLUETTI or register the unit, or you get two years and the gap between these two closes to nothing. Registering a power station takes about as long as reading this paragraph.

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 1000 Air comes up 1,284Wh short (about 39% covered), the AC180 1,121Wh (47%). Treat this as partial cover — enough for the essentials in it, not the whole list.

8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
Neither unit does the full eight hours as specced: 1,645Wh of fridge, lights, phones and internet against 816Wh usable on the DELTA 3 1000 Air and 979Wh on the AC180. Both start and hold the 150W this scenario peaks at, so what runs out is energy, not power. The AC180's extra usable capacity shortens the gap without closing it. With either unit you are choosing between the fridge and everything else by hour five.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP is about 40W, so eight hours comes to roughly 320Wh and both units sleep through it with most of the pack untouched: 496Wh spare on the DELTA 3 1000 Air, 659Wh on the AC180. Capacity has stopped being the question. What is left is the carry, which the lighter Air wins, and whether the unit will still be supported in five years, which the AC180 wins.

AC180
The 910Wh workday is the closest thing to a real gap here. The AC180 finishes with 69Wh in hand; the DELTA 3 1000 Air lands 94Wh short, about 89% of the day covered. Its nameplate 960Wh clears the load on paper, and it is the flat 15% conversion allowance applied to every unit on this site that tips it under, so read it as a day that ends tight rather than a hard fail. Then remember which unit charges the laptop on that desk at 100W over USB-C, and which one manages 18W.

Tailgate Party
Game day power for the crew
AC180
Both cover game day, and the AC180 keeps more back, 68% of its usable energy spent against 82%. This is a light load, though, so the number you feel is the walk from the car: 22 lbs against 35.3. One caveat on the 400W peak. Both start it, but the Air is doing that with 500W of continuous output to its name, so the second appliance someone plugs in is the moment it runs out of tap.

Neither unit
Neither unit covers this scenario's 4,685Wh: the DELTA 3 1000 Air comes up 3,869Wh short (about 17% covered), the AC180 3,706Wh (21%). 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 13, 2026
Verdict: the BLUETTI AC180
Take the AC180. At 960Wh against 1,152Wh the two packs are the same size class, but the Air's inverter tops out at 500W continuous with 1,000W of surge, which rules out a kettle, a microwave and a hair dryer before you have left the kitchenA3. The AC180 has more than three times the continuous output and nearly three times the starting ceiling, charges a USB-C laptop at 100W where the Air manages 18W, and carries up to five years of warranty if you buy direct or register it against the Air's two. The Air is also out of production at EcoFlowA4, so its $309 is clearance pricing rather than a market price, and the ownership advantage it buys comes to one cent per lifetime kilowatt-hour. Choose the Air only if you already own one, or you find one cheap and every load on your list sits under 500W.
Today the AC180 is $449, $50 under its typical $499. The verdict weighs typical prices, not today's. Prices checked 1 day ago.

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 1000 Air rates 5.0/5 (99th percentile of 20 Compact-class units), and AC180 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.
The desk UPS that cannot charge the desk
18W is phone-and-earbuds fast. Most USB-C laptops want at least 60W to charge at full speed, and under load an 18W port may not gain ground at all, which is a strange limit on a unit built to keep a home office running. The workaround is the AC outlet and your laptop's own brick, and it works fine. The AC180 just does it from the port, at 100W.
The ratio flatters, the ceiling decides
The DELTA 3 1000 Air keeps twice its rated output in reserve where the AC180 keeps half again, and that comparison matters less than it looks. A motor draws its startup spike in watts, not as a multiple of whatever inverter it happens to be plugged into. On raw starting ability the AC180 has nearly three times the ceiling. The Air's real advantage is that it runs further below its own limit at steady state, which mostly means it loafs at loads the AC180 would also loaf at.
The one card that goes the Air's way
Rated no worse than 10ms on the DELTA 3 1000 Air against no worse than 20ms on the AC180. Both are published ceilings rather than stopwatch results, and both are quick enough that a router or a TV rides straight through. The difference only bites at the fussy end, where some desktop PC power supplies sit right around the slower line. If the thing you are protecting is a computer with unsaved work, the Air is in the tighter class, and this is the only spec on the page where the discontinued unit is the safer buy.
Warranty: 5 Years vs 2
The AC180 is covered for 5 years against the DELTA 3 1000 Air's 2 years. The AC180's figure is a maximum rather than a guarantee — it depends on buying direct from BLUETTI or registering the unit, since reseller purchases carry a shorter term. An underrated factor if you're keeping this unit for years.

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 phone, email and chat, with outcomes that swing hard: at best a prepaid label and a fast replacement, at worst a long wait and a refurbished unit against a claim for a new one. Buying through Costco or Amazon gives you a return safety net that EcoFlow's own process does not.
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
Fastest-charging technology (X-Stream), deepest product ecosystem, and most active innovation cadence. At the very top of the range, the DELTA Pro Ultra platform stacks batteries and inverters into whole-home backup — a flagship path, not a line-wide feature.
Worth knowing
EcoFlow offers no parts or service once the warranty is up, and the DELTA 3 1000 Air is out of production. On a two-year term, that puts a date on the end of support for this specific unit.
BLUETTI
Ecosystem
One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship portable (Apex 300, 2764.8Wh). Includes specialized products: vehicle solar hubs, sodium-ion cold-weather units, and balcony storage systems.
Support
The least consistent support in the category, heavily email-based and offset by a China timezone. Some claims move smoothly; others turn into weeks of troubleshooting, or an offer of a discount on a new unit instead of a repair. Buying direct from BLUETTI improves the odds, and it is also how you get the five-year term.
Community
Active and growing — Reddit r/bluetti has a dedicated community. Second-largest after EcoFlow in engagement.
App experience
Rated 4.5/5 iOS and Android — tied for best app experience in the category. V3.0 UI redesign was well-received.
Unique strength
Among the best capacity-to-price ratios available — several Elite and Apex units are the lowest $/Wh in the catalog. Widest product diversity including industry-firsts like sodium-ion cold-weather units and dual solar+alternator vehicle hubs. LFP across the rest of the range, though rated cycle life spans 2,500 (EB3A) to 6,000, and it varies WITHIN the Elite range rather than tracking it — the Elite 300 and Elite 200 V2 are rated 6,000 while the Elite 30 V2, Elite 10 Mini, Elite 320 and Elite 400 are rated 3,000+ and the Elite 100 V2 4,000+, so check the specific model. Dual-voltage (120V/240V) in flagships.
Worth knowing
Rated cycle life varies widely across BLUETTI's lineup, so the AC180's 3,500-cycle figure belongs to the AC180 and is not a house standard. Discontinued BLUETTI units can become unrepairable too, which is an argument for buying the one still in production.
Analyst note
Neither brand is a reason to buy here. EcoFlow has the deeper ecosystem and the larger community; BLUETTI sits at the value end of the category with steadier app ratings across platforms. Both have support you would rather not test. What actually separates them on this page is that one of these two units is still being made, and for the other one, the warranty is the last service you will get.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 1000 Air
Field data on the Air is thin, and what exists comes from reviewers rather than long-term ownersA0A1. The consistent read across that coverage is a deliberately minimal machine: 960Wh of LFP, 22 lbs, fewer ports than EcoFlow usually ships, and a 500W inverter with an 800W X-Boost mode that reviewers say will not carry a space heater or a hair dryerA1A3. It was reviewed as a power-protection device first, with the 10ms UPS rating treated as the point of the product rather than a feature of itA2.
Nobody has been living with this unit for three years, and now nobody will start, because EcoFlow has stopped selling itA4. Treat every long-term claim about it, ours included, as inference from the spec sheet.
“A 960Wh LiFePO4 unit with a 500W inverter (800W X-Boost) weighing only 22 lbs — a focused, minimalist design with fewer ports and features.”

BLUETTI AC180
The AC180's coverage is deep and lands in the same place twice: the most raw power and capacity per dollar in the mid-range at around $499B4, with the weight as the recurring complaintB2. One reviewer named moving it around their single biggest frustrationB2. Weight is cited inconsistently across sources at roughly 35 to 37 lbs, and our listing uses 35.3B0.
Fan noise splits the room. Some coverage calls it fairly quiet from a few feet away, other coverage calls the fans aggressive under load and especially while charging, and there is a silent charging mode that caps the noise by slowing the chargeB1. If it is going in a bedroom, plan on that mode and on the slower refill it implies. The cells themselves draw no complaints: 3,500-plus full cycles before capacity falls to 80%, with the five-year term behind themB3.
“Fan noise draws mixed reports — some find it fairly quiet from a few feet, others call the fans aggressive and loud, especially during charging; a silent charging mode caps the noise by limiting charge speed.”

“The definition of bang for buck — not the lightest or smartest, but the most raw power and capacity for the price; widely called the best value in the mid-range at around $499.”

Who Should Buy Which
Buy the DELTA 3 1000 Air if you…
- →You already own one, or you have found clearance stock well under what the AC180 costs, and you can name every load it will ever see: laptop, monitors, router, phone, a CPAP. All of those sit under 500W with room left over.
- →The thing you are protecting is a desk you cannot afford to lose mid-outage, the unit never moves from under it, and you can still find one discounted. A rating of no worse than 10ms is the best reason on this page to choose the Air, and it is a real one.
- →You carry the unit far more often than you load it heavily, and you have found one at a clearance price. Thirteen fewer pounds in and out of a trunk every weekend is a different life, and the CPAP night both units cover with hundreds of watt-hours spare does not care which one you brought.

Buy the AC180 if you…
- →You want one box for whatever comes up. 1,800W continuous with 2,700W of starting headroom takes the loads a 500W inverter refusesA3, and you never have to audit an appliance before plugging it in.
- →You work off it. 979Wh of usable energy finishes the 910Wh remote-workday load with 69Wh in hand, and the 100W USB-C port charges the laptop while it does.
- →You are buying backup to sit in a closet for years. Buy direct or register it, take the five-year term, and know the cells are rated past 3,500 cyclesB3.
- →You want the unit that is still in production, at a price you can verify and with stock you can replace.
If neither fits
If your list includes a fridge running all day, a van's daily draw at 4,685Wh, or a full eight-hour blackout's worth of house at 1,645Wh, close this tab. Neither unit covers any of those, and adding a second battery later is not an option because neither one expands. What you want is a station two or three times this size with expansion behind it, bought once, instead of a 1kWh unit you will outgrow in the first outage that matters.
The Bottom Line
Same battery class, very different taps. Five hundred watts on one side, 1,800W on the other, and every other difference on this page runs downstream of that. The Air is a good desk UPS that EcoFlow has stopped building. The AC180 is a power station.
Buy the AC180, register it for the longer term, and take the extra thirteen pounds as the price of a unit that finishes the job. The one argument the other way is honest: if what you are protecting is a desktop with unsaved work, the Air's tighter UPS class is real, and it is the one you will actually carry. If you already own one, or you find one cheap and every load you own is light, use it happily. Just do not pay for it as though it were still in production.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow DELTA 3 1000 Air discontinued?
Yes. EcoFlow no longer sells it, and the closest replacement in its own line is the DELTA 3 Classic, which puts an 1,800W inverter in the same one-kilowatt class. Anything you find now is retailer or clearance stock. That is no reason to dump a unit you already own, and it is a good reason not to pay full price for one.
Can the DELTA 3 1000 Air run a fridge or a microwave?
Not a microwave, and not a fridge you would count on. It is 500W continuous with 1,000W of surge, which rules out heating elements outright: no kettle, no hair dryer, no space heater. A compressor draws its startup spike in watts rather than as a multiple of your inverter's rating, so that 1,000W ceiling is the whole answer. The AC180 runs 1,800W and starts 2,700W.
Which one is better for a CPAP?
Either. A CPAP is about 40W, so a night comes to roughly 320Wh, and both units finish it with hundreds of watt-hours unused: 496Wh left on the Air, 659Wh on the AC180. With capacity a formality, choose on what you will actually notice. The Air is the lighter carry to a campsite; the AC180 has years of warranty behind it and is still being made.
Is the BLUETTI AC180 worth $190 more than the DELTA 3 1000 Air?
If any load on your list goes over 500W, yes. The gap is not firmly $190 either: the AC180's $499 is a baseline we track, while the Air's $309 is a single spot capture on a unit EcoFlow has discontinued, so what you actually pay depends on what stock is left. Per lifetime kilowatt-hour the two are one cent apart, so the Air is not buying you cheaper energy. It is buying you a smaller tap.
Does the BLUETTI AC180 really have a 5-year warranty?
Up to five years, with a condition: buy direct from BLUETTI or register the unit. Bought through a reseller and left unregistered, it is two years, the same term the Air carries. Five years on a $499 unit works out to $100 per covered year against $155 for a $309 unit covered for two, so the registration step is worth the five minutes it takes.
