Spec deltas
The BLUETTI AC180P wins this, and the extra 480Wh of capacity has almost nothing to do with it. It runs 1,800W continuous against the DELTA 3 1000 Air's 500W. That is not a spec gap you weigh against price. It is the line between a power station and a desk accessory.
The DELTA 3 1000 Air is a good desk accessory, to be fair to it. 22 lbs, a 10ms transfer to battery, and 960Wh is a sensible amount of energy to keep a computer, a monitor and a router alive through an outageA2. At $309 against the AC180P's $649 it is $340 cheaper. If your whole load lives on one power strip, that is a serious buy.
Then there's the complication: EcoFlow no longer sells itA4. The named replacement, the standard DELTA 3, runs about $549 and matches the AC180P's 1,800W outputA4, which puts you $100 from the BLUETTI instead of $340 below it, with the inverter argument gone entirely. Find out whether you can actually buy a DELTA 3 1000 Air before you spend any time on the rest of this page. That single fact rewrites the comparison.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
There is no rationing your way through the last 94Wh. A 94Wh miss doesn't read as a capacity limitation you plan around; it reads as a screen going dark at four in the afternoon with the day's work unsaved. The gap between covering 90% of a workday and covering all of it is the entire value of the unit for that job.
DELTA 3 1000 Air holds 960Wh, which is 816Wh usable after the 15% inverter derate the scenario model appliesThe Remote Workday scenario draws 910WhAC180P holds 1,440Wh, or 1,224Wh usable on the same basis
Why it mattersAnyone planning to work a full day off battery should buy the AC180P. The DELTA Air is a half-day machine no matter how carefully you budget it.
That routing has a cost the spec sheet hides. Every watt you push through an AC socket goes through the inverter, which is the same 15% the scenario model derates for, and it consumes an outlet you might have wanted for something else. The AC180P's 100W port takes the laptop off the inverter entirely and hands it a charger that matches what the machine actually wants.
DELTA 3 1000 Air was built as a power-protection device to keep a computer, monitor and router running through outages, on a 10ms switchoverA2Its fastest USB-C port outputs 18W; the AC180P's outputs 100WIt is rated 500W continuous and is meant for low-to-moderate draw devicesA3
Why it mattersIf your outage plan is a laptop on a USB-C cable, the DELTA Air is the wrong box regardless of price.
continuous output
A startup spike is measured in watts, not multiples. A compressor or a heating element has no idea what percentage of its host's rating it represents, and the DELTA Air can't even attempt loads the AC180P holds all day at steady state. The ratio is a fact about the inverter's relationship to itself, not about what you can plug in.
DELTA 3 1000 Air: 500W continuous, 1,000W surge, a 2x ratioAC180P: 1,800W continuous, 2,700W surge, a 1.5x ratio500W won't run a space heater or a hair dryerA3
Why it mattersIf anything on your list has a motor or a heating element, the surge ratio is a distraction and the DELTA Air is out of the running.
cost / lifetime kWh
At $309 you are making a defensible gamble: a discontinued unit, three fewer warranty years, and a company that won't service it afterward, in exchange for real money saved. Swap in the successor's $549A4 and the gamble evaporates. You are $100 from the AC180P, matched on inverter output, and behind on warranty and capacity, with nothing left on the table to argue about.
$309 across 3,000 cycles of 960Wh is $0.11 per lifetime kWh; $649 across 3,500 cycles of 1,440Wh is $0.13EcoFlow no longer sells the DELTA 3 1000 Air, and the closest successor, the standard DELTA 3, runs about $549A4DELTA Air carries a 2-year warranty against the AC180P's 5, and EcoFlow offers no parts or service out of warranty
Why it mattersCheck stock before you check specs. The price that makes this matchup interesting is the one most likely to be gone.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Six scenarios, and the closest one is decided by 94Wh of a 910Wh day.
The number to hold onto is 94. A remote workday draws 910Wh in this model, and the DELTA 3 1000 Air has 816Wh usable once you apply the 15% inverter derate. It covers roughly 90% of the day and quits. The AC180P walks out of the same day with 314Wh left.
Everything else sorts into two clean piles. A 320Wh CPAP night is a formality for both, leaving 496Wh spare on the DELTA and 904Wh on the AC180P, so capacity has nothing to say there. And the three heavy scenarios are beyond both units: an eight-hour blackout at 1,645Wh leaves the DELTA 829Wh short and the AC180P 421Wh short, and van life at 4,685Wh a day isn't a conversation either box belongs in. When both units fail the same scenario, failing by less isn't a win. It's a signal to go up a class.
What the Specs Don't Tell You
Selected because: Output, USB-C and surge headroom are where these two stop being comparable: 18W against 100W, and a 1,000W peak against 2,700W.
rated cycles
18W is the number that gives the DELTA 3 1000 Air away. This is a unit built as power protection for a workstationA2, and its fastest USB-C port can't keep a modern laptop topped up while you use it. You'll be running the laptop's wall brick through an AC socket instead, which works, but it spends an outlet and puts the load through the inverter. The AC180P's 100W port sidesteps both.
The surge card rewards slow reading. Twice the continuous rating in reserve sounds better than one and a half times, right up until you notice the AC180P's ordinary all-day rating is 800W above the best single moment the DELTA Air can produce. Headroom is only interesting relative to a ceiling worth having.
Brand Trust
Selected because: Five years of warranty against two, and the two brands differ on what happens once that window closes.
Five years against two is the plainest gap on this page, and it compounds with something the warranty card doesn't say: EcoFlow offers no parts or service out of warranty. Buy the DELTA 3 1000 Air and year three onward is entirely your problem, on a model the company has already stopped sellingA4.
BLUETTI's side isn't spotless. Its own caveat is that older discontinued units can become unrepairable with no spare-parts policy, and support runs on email across a China timezone, so a five-year card is only as good as the queue behind it. The difference is timing. That's a risk the AC180P might grow into. It's one the DELTA Air already has.
Lifetime Value
Selected because: $0.11 against $0.13 per lifetime kWh is a rounding error. The $340 at the register is not.
cost / lifetime kWh
Two cents is the entire spread in lifetime energy cost. $309 across 3,000 cycles of 960Wh works out to $0.11 per kWh; $649 across 3,500 cycles of 1,440Wh comes to $0.13. Neither number should move you an inch, and any page that leads with them is padding.
What matters is the $340 between them at the register, and it carries an asterisk. The DELTA Air's $309 is a single spot capture with no price history behind it, on a model EcoFlow no longer listsA4. That is what a discontinued unit's price looks like on its way out the door. Per watt-hour it is genuinely the cheaper box, $0.32 from $309 over 960Wh against $0.45 from $649 over 1,440Wh, and that advantage lasts exactly as long as the remaining stock does.
Portability & Form Factor
Selected because: 22 lbs against 35.3 lbs, which is the difference between one hand and two.
weight
22 lbs is a grab-it-and-go weight. 35.3 lbs is both hands and a plan for where you're setting it down. Across a parking lot, up basement stairs, in and out of a trunk twice a weekend, the 13.3-lb difference between them is real, and it is the DELTA Air's second-best argument after price.
What the extra 13.3 lbs buys is 480Wh of capacity and 1,300W more continuous output, which is the most honest trade on this page. Nobody has ever regretted the lighter box on the stairs. Plenty of people have regretted one that wouldn't start what they plugged into it.

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 AC180P 876Wh (58%). Treat this as partial cover — enough for the essentials in it, not the whole list.

Neither unit
Neither unit gets you through all eight hours. The 1,645Wh load leaves the DELTA 3 1000 Air 829Wh short and the AC180P 421Wh short, so both are a triage exercise rather than a full-cover plan. Decide in advance which two loads stay on, and either box becomes useful instead of disappointing.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
DELTA 3 1000 Air
Capacity is a formality here. 320Wh against 816Wh and 1,224Wh usable means both units cover the night with 496Wh and 904Wh left over respectively, so the question is what you are paying for reserve you will never touch. The DELTA 3 1000 Air asks $309 against the AC180P's $649. For a CPAP and nothing else, the smaller, lighter, cheaper box is the right answer.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h

AC180P
94Wh. That is the entire margin: a workday draws 910Wh in this model and the DELTA 3 1000 Air has 816Wh usable, so it covers about 90% of the day and then quits. The AC180P finishes with 314Wh still in the tank. Ninety percent of a workday is not a partial win, it's a late-afternoon blackout with extra steps.

AC180P
Both units run game day, so this comes down to the walk from the car. The DELTA 3 1000 Air is 22 lbs and finishes the 670Wh day with 146Wh left; the AC180P is 35.3 lbs and finishes with 554Wh left. The AC180P takes it on reserve. But if the lot is far and the cooler already has your other hand, the lighter box is the one you'll be glad about.

Neither unit covers this scenario's 4,685Wh: the DELTA 3 1000 Air comes up 3,869Wh short (about 17% covered), the AC180P 3,461Wh (26%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Conclusion
August 9, 2026
Verdict: the AC180P, on Power Score margin
Buy the AC180P at $649 unless your entire load is a desk. The DELTA 3 1000 Air's 500W continuous ceiling isn't a soft limit you work around; it rules out heating elements and big motors outrightA3, and it's why the unit misses a 910Wh remote workday by 94Wh of its 816Wh usable while the AC180P finishes that day with 314Wh still in the tank. Stack on a 5-year warranty against 2, a 100W USB-C port against 18W, and the fact that EcoFlow no longer sells the DELTA AirA4, and the $340 you save is buying a narrower machine with a shorter support life. One clean exception: if you want a 22-lb box that holds a computer, monitor and router up on a 10ms transferA2, and you can find one at $309, the DELTA Air does that job and the AC180P is $340 of overshoot.

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 AC180P rates 4.1/5 (50th 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.
39dBA vs 45dBA, and Why It Shouldn't Decide This
The published figures are 39dBA for the DELTA 3 1000 Air and 45dBA for the AC180P. Both are full-load ratings from bucketed spec data rather than measurements taken in a quiet room, so treat the 6dBA gap as a hint about fan sizing, not a promise about your bedroom. What actually sets fan speed is load, and a 320Wh overnight CPAP draw works either unit lightly. Run either one hard in a small room and you'll hear it.
18W USB-C on a Unit Built for a Desk
The DELTA 3 1000 Air's fastest USB-C port delivers 18W. The AC180P's delivers 100W. That is the gap between charging a phone and charging a laptop, and it's an odd limit on a box whose stated purpose is keeping a workstation alive. Plan on running your laptop's wall brick through an AC socket instead. It works, but it spends an outlet and routes the load through the inverter. If USB-C is how you charge everything, only one of these two is set up for it.
The Ratio Flatters the Smaller Inverter
The DELTA 3 1000 Air keeps twice its continuous rating in reserve, 1,000W peak over 500W continuous. The AC180P keeps one and a half, 2,700W over 1,800W. On the multiple alone the DELTA looks like the one with headroom. Read the ceilings instead: the AC180P's continuous rating is 800W above the best single moment the DELTA Air can produce. A startup spike is measured in watts, not multiples, and only one of these two has 2,700W available to absorb one.
10ms vs 20ms, and a Real Win for the Smaller Box
The DELTA 3 1000 Air transfers to battery in 10ms as a line-interactive unit; the AC180P takes 20ms in standby. Both sit inside what a desktop PC, a router or a CPAP will ride through, so for ordinary equipment this is a tie on paper. The DELTA's margin buys room for the fussier stuff, an older desktop power supply or a NAS caught mid-write, and it is the clearest thing the smaller unit does better than the bigger one.
Five Years vs Two
Straight comparison: the AC180P carries a 5-year warranty and the DELTA 3 1000 Air carries 2. That's the whole card, and it beats any per-dollar arithmetic you can do with it, because the risk isn't spread evenly across those years. EcoFlow offers no parts or service out of warranty, so on the DELTA Air, year three is where you're on your own.

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 runs the deepest lineup in portable power and the most active innovation cadence, and both cut the same way: models turn over quickly, and the company offers no parts or service once the warranty expires. Against a two-year window, that puts a clock on this unit sooner than you'd expect. Also on the record, on a different model in the same DELTA family: an October 2025 recall of the DELTA Max 2000 for overheating and fire risk, across six incidents.
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 most inconsistent support in the space. Heavily email-based with China timezone delays. Some users get smooth, efficient service; others report weeks of troubleshooting runarounds, being offered discounts on new units instead of repairs, and confusing third-party purchase claim processes. Buying direct from Bluetti's website tends to produce better support outcomes.
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
BLUETTI's five-year warranty is the longest thing on this page, and the brand's own caveat is the reason to read it carefully. Support is heavily email-based across a China timezone and outcomes vary widely. Buying direct from BLUETTI rather than through a third party is the single change that most improves how a claim goes. The app is the best-rated in the category at 4.5 on both platforms, which counts for something at two in the morning.
Analyst note
Two different failure modes rather than a good brand and a bad one. EcoFlow gives you the larger ecosystem, a US phone line, and a hard stop at the end of the warranty. BLUETTI gives you five years instead of two and a queue that can be slow to answer within them. If you expect to need help, weigh how you'll ask for it: EcoFlow has a number you can call, BLUETTI has a longer window in which to call it.

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 DELTA 3 1000 Air is thin, and what exists comes from reviewers rather than long-term ownersA1A2. Their account is at least coherent: a deliberately minimalist 960Wh LFP box with fewer ports and features than its siblingsA1, built specifically as a power-protection device to carry a computer, monitor and router through an outage on a 10ms switchoverA2. The consistent caution is output, with 500W continuous ruling out a space heater or a hair dryer and steering the unit toward low-to-moderate drawA3. There is no long-term ownership record here at all, so treat durability as unproven rather than goodA1A2.
One ledger item outranks every review note. EcoFlow no longer sells the DELTA 3 1000 Air, with the standard DELTA 3 at 1,024Wh and 1,800W output, around $549, named as the closest replacementA4. That rests on a single sourceA4, so confirm stock yourself rather than take it on faith. It does line up with a $309 price that has no capture history behind it.

BLUETTI AC180P
The AC180P has the deeper record: 4.6 stars from 708 verified Amazon purchasersB2, and reviewers who put the Turbo Charge claim on a clock and got 0 to 80% in roughly 45 minutes, as advertisedB1B2. Power Lifting Mode is the other repeated note, delivering 2,700W for high-draw devicesB1.
Two corrections worth carrying into the purchase. Some listings mark the AC180P as expandable; it has no battery expansion port and will not add capacity from a B80, B230 or B300, though those packs can charge it through Power Bank ModeB3. And weight is cited around 35 lbs in most places, with one outlier near 28.7 lbsB4. Our spec uses 35.3, so plan for the heavier figure.
“Delivers 1,440Wh of LiFePO4 capacity and 1,800W continuous output, with a Turbo Charge feature reaching 0-80% in roughly 45 minutes and a Power Lifting Mode that delivers 2,700W to run high-powered devices.”

“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).”

“Delivers 1,440Wh of LiFePO4 capacity and 1,800W continuous output, with a Turbo Charge feature reaching 0-80% in roughly 45 minutes and a Power Lifting Mode that delivers 2,700W to run high-powered devices.”

“Does not include a battery expansion port and does not support capacity expansion with B80, B230, or B300 batteries — contrary to some listings — though it can be charged by such batteries through Power Bank Mode.”

“Weight is cited around 35 lbs in most listings (one source lists ~28.7 lbs) — manageable for base camp or car camping, more of a constraint for backpacking or carrying any distance.”

Who Should Buy Which
Buy the DELTA 3 1000 Air if you…
- →Your load is one power strip: a desktop or a laptop brick, a monitor, a router and a modem. The DELTA Air was designed for exactly that, with a 10ms transfer so the machine never notices the utility leftA2.
- →You want the lightest box that still holds 960Wh. At 22 lbs it goes into a trunk one-handed and up a flight of stairs without ceremony.
- →Your night is a CPAP and nothing else. 320Wh against 816Wh usable is 39% of the tank, and the AC180P's extra $340 would be buying 904Wh of reserve you will never open.

Buy the AC180P if you…
- →Something in your plan has a compressor or a heating element. 1,800W continuous with a 2,700W peak starts loads the DELTA Air cannot attempt against its 1,000W ceiling.
- →You work a full day off it. The AC180P covers a 910Wh workday with 314Wh in hand; the DELTA Air comes up 94Wh short of the same day.
- →You charge over USB-C. 100W is a laptop's real charger. 18W is a phone's.
- →You are keeping it past year two. Five years of warranty against two, on a model that is still in the lineup.
If neither fits
Van dwellers and long-weekend campers should close this tab cheerfully. A day of van life runs 4,685Wh in this model, which the AC180P covers about 26% of and the DELTA Air about 17%, and a 2,100Wh camping weekend leaves even the bigger unit 876Wh short. That calls for a substantially larger station with real battery expansion. Neither of these expands at all, so there is no upgrade path out of the problem once you've bought one.
The Bottom Line
Take the AC180P. 1,800W continuous against 500W isn't a feature comparison, it's a category line, and the DELTA 3 1000 Air sits on the wrong side of it for any load with a motor or a heating elementA3. The 94Wh it misses a remote workday by is that same wall in miniature: not a shortfall you plan around, just the exact point where the lights go out.
The honest version of the other case: at $309 for a 22-lb box that holds a desk up on a 10ms transferA2, the DELTA Air is a good buy and the AC180P is $340 of machine you don't need. That's a real recommendation for a real person. It just isn't most people, and it depends on finding one in stock, which is the part EcoFlow has already decided againstA4.
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 is the standard DELTA 3 at 1,024Wh and 1,800W output for around $549. That matters more than any spec here: at $309 the DELTA Air undercuts the AC180P by $340, but the successor matches the AC180P's 1,800W output, so at $549 against $649 you would be comparing capacity and warranty rather than two different classes of machine. Confirm you can actually buy one before planning around the cheaper number.
Will the DELTA 3 1000 Air run a space heater or a hair dryer?
No. It is rated 500W continuous with a 1,000W peak, and it is built for low-to-moderate draw devices rather than heating elements. The AC180P, at 1,800W continuous and 2,700W peak, is the one of these two with a realistic shot at high-draw appliances. Check the wattage label on the appliance and compare it against the continuous rating, not the peak, because the peak only covers the first moment.
Which one is quieter?
The published figures are 39dBA for the DELTA 3 1000 Air and 45dBA for the AC180P, but don't decide on them. Both are full-load ratings drawn from bucketed spec data rather than measurements we took ourselves. Load matters far more than the label: a CPAP night is 320Wh against 816Wh and 1,224Wh of usable capacity, a small enough draw that neither fan is working hard.
Is the BLUETTI AC180P expandable?
No. It has no battery expansion port and will not add capacity from a B80, B230 or B300 despite what some listings claim; those packs can only charge it through Power Bank Mode. The DELTA 3 1000 Air doesn't expand either. Both are complete units at a fixed size, so buy the capacity you need on day one, 1,440Wh or 960Wh, with nothing added later.
Is the AC180P worth $340 more than the DELTA 3 1000 Air?
If anything you plug in draws more than 500W, yes, and it isn't close, because that is the DELTA Air's continuous ceiling and no price advantage moves it. If your load is a desk that stays under 500W, no: you would be paying $340 for 480Wh and an inverter you never use. For everyone in between, availability breaks the tie, since EcoFlow no longer sells the DELTA Air.
