Head-to-head test
EcoFlow DELTA 3 Classic vs BLUETTI AC60P
The AC60P's entire case is its IP65 shell: BLUETTI asks $749 and 504Wh where EcoFlow asks $469 and 1,024Wh, so the only real question is whether your power station needs to survive weather.

Spec deltas
Buy the DELTA 3 Classic. It's $469 against the AC60P's $749, and the cheaper box is also the bigger one: 1,024Wh against 504Wh, 1,800W of inverter against 600W, a 500W solar ceiling against 200W. Cheaper is normally the compromise. Here it's the upgrade.
The AC60P leads exactly two rows of the spec table. It weighs 21.2 lb against the EcoFlow's 26.7 lb, and it carries six years of warranty against five. Its third advantage isn't on the table at all: an IP65 rating against dust and low-pressure water jets, on LiFePO4 cellsB1, which is what the AC60 platform is known forB4. If your unit lives in a truck bed or on a job site, start there and stop reading.
Everyone else is paying $280 more, the difference between $749 and $469, for a rating they'll never test. Both units are rated for the same 3,000 cycles, so time doesn't rescue the AC60P's math either. What it costs per watt-hour at checkout is what it costs per watt-hour at the end of its life.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
There is no ownership horizon that fixes this. A pricier unit that outlasts its rival can be argued about; a pricier unit with the same cycle rating and half the tank cannot. The AC60P's $749 is buying something other than energy, and if you can't name what that something is, you are simply overpaying.
DELTA 3 Classic: $469 for 1,024Wh, $0.46 per watt-hourAC60P: $749 for 504Wh, $1.49 per watt-hourBoth units rated at 3,000 cycles
Why it mattersAnyone comparing these two on value can stop at the first row of the table.
continuous output
The EcoFlow's inverter opens a whole class of appliance the AC60P can't address, and the same testing shows exactly where that stops: it starts the compressor, it just can't feed it for longA10. That's the accurate way to hold both units. One of them starts more things; neither runs them all night.
DELTA 3 Classic: 1,800W continuous, 3,600W surgeAC60P: 600W continuous, 1,200W surgeReview testing found the 1,800W inverter starts a small window air conditioner without trouble, but the runtime is shortA10
Why it mattersIf anything on your list has a compressor or a heating element, the AC60P is eliminated on the spec sheet before you even reach the price.
solar input
An input ceiling is the one thing you can't buy your way past. Reviewers wanted more than 500W out of the EcoFlow and they have a pointA5A9, but 200W means an overcast morning can't be answered by adding another panel. On a marginal-sun day the unit with more headroom recovers and the other one doesn't, even though neither hits its rating.
DELTA 3 Classic: 500W solar input ceiling on 1,024WhAC60P: 200W solar input ceiling on 504WhTwo review outlets flag the EcoFlow's 500W cap as low for a 2026 release, one noting the display topped out at exactly 500WA5A9
Why it mattersSolar-first buyers should treat the input ceiling as the spec that decides whether the unit ever catches up, and take the EcoFlow.
weight
An ingress rating is binary in a way capacity never is. Either you need the box to sit in blowing dust or take a hose without a second thought, or you don't, and no quantity of EcoFlow watt-hours substitutes for itB1. The sixth warranty year rides in the same direction. That is a genuine product, priced at $749, for a genuinely narrow buyer.
AC60P: 21.2 lb, rated IP65 against dust and low-pressure water jetsB1DELTA 3 Classic: 26.7 lb, with no equivalent ingress rating anywhere in our dataAC60P warranty six years against the DELTA 3 Classic's five
Why it mattersJob-site, boat and open-truck-bed buyers should take the AC60P and accept the capacity hit. Everyone else is paying for weatherproofing they'll store in a closet.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The AC60P costs $749 against the DELTA 3 Classic's $469 and holds 504Wh against 1,024Wh, so the money question is settled before anything else on this page gets a vote.
cost / lifetime kWh
This table has one live number in it and it's the cost per watt-hour. Both units carry the identical 3,000-cycle rating, so cost per lifetime kilowatt-hour, $0.15 against $0.50, can only ever restate the purchase price divided by the capacity you got for it. It cannot reorder these two, and it isn't independent evidence.
Read the lifespan rows with particular suspicion. The DELTA 3 Classic and the AC60P both print 8.2 years of daily cycling, 57.7 years of weekly use and 28.8 years of weekend use, and they print identical figures because that calculation counts cycles and ignores capacity entirely. One box holds 1,024Wh and the other holds 504Wh, and the lifespan row cannot see the difference. The row that does say something is cost per warranty year: $94 for the EcoFlow across five years against $125 for the BLUETTI across six.
Runtime: Will It Power Your Gear?
Selected because: 870Wh of usable energy against 428Wh is what decides which jobs each unit finishes, and it's the gap the price never excuses.
continuous output
Neither of these is a whole-house anything, so the useful question is how far short each one falls. We score every unit against 85% of its nameplate, a flat allowance applied across the whole catalog rather than a measurement of either box, which puts the DELTA 3 Classic at 870Wh usable and the AC60P at 428Wh.
That gap changes the kind of failure you get, not just its size. On a 1,645Wh eight-hour blackout the EcoFlow comes up 775Wh short and the BLUETTI 1,217Wh short. On a 910Wh remote workday the EcoFlow misses by 40Wh while the BLUETTI misses by 482Wh. A 40Wh miss is a monitor you turned off. A 482Wh miss is a different purchase.
Portability & Form Factor
Selected because: At 21.2 lb against 26.7 lb, and rated IP65 for dust and water jets, this is where the AC60P's whole case for costing more actually lives.
weight
Both of these are one-person carries, and the 5.5 lb between the AC60P's 21.2 lb and the DELTA 3 Classic's 26.7 lb won't change that. Reviewers describe the EcoFlow's handle as solid and centeredA11, which does more for your wrist across a parking lot than five and a half pounds does.
What the AC60P really offers here is the shell. IP65 means dust-tight and rated against low-pressure water jets from any direction, not submersible, and it's why the AC60 platform gets praised as the one you can simply take placesB1B4. That is a real difference, and it deserves an honest price tag: it costs the $280 between $749 and $469, and it buys you nothing whatsoever if the unit lives indoors.
What the Specs Don't Tell You
Selected because: Three flags fire here: 45dB against 30dB under load, a 10ms against 20ms switchover, and the AC60P's extra warranty year.
The noise flag is the one to act on. 45dB rated for the AC60P against 30dB for the DELTA 3 Classic is a fifteen-decibel gap on a box that some buyers park beside the bed, and if a CPAP is why you're shopping, that single row outweighs everything the BLUETTI wins.
The other two flags are quieter than they look. A 10ms switchover against 20ms is a gap between two rated ceilings, and both sit well inside what a router, a desktop or a CPAP rides out without noticing. The warranty flag is genuinely real: six years against five, and it is the AC60P's second and last win on this table.
Brand Trust
Selected because: Warranty is the AC60P's second and last win at six years against five, and a warranty is worth exactly what the service desk behind it is worth.
The software is a coin flip. Our brand data puts EcoFlow's app at 4.6 on iOS and 4.2 on Android against BLUETTI's 4.5 on both, and reviewers of the DELTA 3 Classic single out the app and its Storm Guard auto-charge as the standout software hereA6A12. Nobody should pick between these two on an app score.
Service is where the brands actually diverge, and it cuts against the more expensive unit. Our brand assessment rates BLUETTI's support the most inconsistent in the category, heavily email-based with timezone delays, while EcoFlow's is polarized rather than dependable. Both companies also draw a hard line at the end of coverage: EcoFlow offers no parts or service out of warranty, and BLUETTI has no spare-parts policy for some older models. If the sixth year is what's tempting you toward the AC60P, you're buying the coverage and the claims desk as one package.

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 of these finishes a 2,100Wh weekend. The DELTA 3 Classic stops 1,230Wh short and the AC60P 1,672Wh short, which means this row is sized for a different class of station rather than for either unit here. If your weekend genuinely looks like this, buy a bigger box, or bring panels and plan on refilling mid-trip.

Keep the essentials running through a night without power
Neither unit
Both units go dark before the lights come back on a 1,645Wh outage. The DELTA 3 Classic ends 775Wh short with 870Wh of usable energy behind it; the AC60P ends 1,217Wh short with 428Wh. Same verdict, very different distances. Trim the list to a fridge cycle, the router and phones and the EcoFlow becomes genuinely useful, while the BLUETTI needs that list cut a second time.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
DELTA 3 Classic
Both cover the night without effort: a CPAP at roughly 40W for eight hours is 320Wh, and neither unit is troubled by that. The split is the second night. The DELTA 3 Classic finishes with 550Wh of its 870Wh usable still in reserve, which is another full night and change. The AC60P finishes with 108Wh of its 428Wh, which is not. In an outage that runs past breakfast, that is the whole difference.

Neither unit
A 910Wh workday beats both of them, but only barely in one case. The DELTA 3 Classic ends the day 40Wh short, so skipping the second monitor on the last call, or topping up over lunch from a panel, gets you home. The AC60P is 482Wh short, which no amount of trimming fixes. Score this one a near-miss and a flat no.

The DELTA 3 Classic covers this 670Wh afternoon and still holds 200Wh of its 870Wh usable in reserve. The AC60P has 428Wh to work with and comes up 242Wh short, which in tailgate terms is the last stretch happening in the dark. Tank size settles this one, not inverter class.

Full-time van power is a wired system with an alternator charger and a roof of panels, not a portable box that also goes camping. Read this row as a size check rather than a comparison.

Conclusion
August 9, 2026
Verdict: the DELTA 3 Classic
The DELTA 3 Classic is the cheaper unit and the stronger one on every spec that decides what a power station can actually do: 1,024Wh against 504Wh, 1,800W continuous against 600W, 3,600W surge against 1,200W, 500W of solar input against 200W, 30dB against 45dB, 10ms switchover against 20ms, and $0.46 per watt-hour against $1.49. The AC60P leads two rows, weight at 21.2 lb against 26.7 lb and warranty at six years against five, plus an IP65 rating for dust and low-pressure water jets that isn't on the spec table at allB1. Pay the $280 between $749 and $469 only if that enclosure is the point of the purchase. For a unit that lives in a closet and comes out for outages, camping and a CPAP, the EcoFlow is both the better machine and the cheaper one, and those two rarely arrive together.

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 Classic rates 4.9/5 (92nd percentile of 26 Everyday-class units), and AC60P rates 3.4/5 (5th percentile of 20 Compact-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.
Fan Noise Under Load: 45dB vs 30dB
The AC60P is rated 45dB under load against the DELTA 3 Classic's 30dB. For a box that sits beside the bed, that gap is the most decision-relevant row on this page, and it points at the EcoFlow. Two honest cautions: both figures are rated numbers rather than our own measurements, and neither one tells you how the fan behaves at a 40W trickle as opposed to a hard recharge. Buy the quieter rating if the unit sleeps in the bedroom, but don't read 30dB as a promise of silence.
Switchover: 10ms vs 20ms, Both Rated Ceilings
The DELTA 3 Classic is rated to switch to battery within 10ms and the AC60P within 20ms. Both of those are stated ceilings rather than stopwatch results, and both sit inside what a desktop, a router or a CPAP will ride through without noticing. Treat this as a tie unless you're feeding something genuinely fussy. It is a real difference on paper and almost never a difference in your house.
Warranty: Six Years vs Five
The AC60P carries six years against the DELTA 3 Classic's five, and that is a real point for the more expensive unit. Worth stating plainly, because it is one of only two rows on this table where the BLUETTI leads. What a warranty is worth also depends on the desk behind it, and our brand assessment rates BLUETTI's support the most inconsistent in the category while rating EcoFlow's as polarized rather than reliably good. An extra year is worth less than it sounds if the claim takes a month to move.

One thing to know reading the table: both carry the same 3,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.

App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
The EcoFlow advantages that actually reach this price bracket are charge speed and software: X-Stream fast charging, the deepest model lineup in portable power, and the fastest release cadence in the category. Ignore the headline number about 180kWh of modular expansion. That belongs to the DELTA Pro Ultra X, a different machine at a different price, and it has no bearing on what a 1,024Wh DELTA 3 Classic will ever be asked to do.
Worth knowing
The October 2025 recall EcoFlow issued covered the DELTA Max 2000, a different model, and it shouldn't be read as a verdict on this one. The policy that does apply to you: EcoFlow offers no parts and no service once the warranty is up, so year six is on you. The company also trialled a subscription paywall for advanced app features in early 2025 and shelved it after the backlash, which is worth knowing if part of what you're buying is the app.
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
BLUETTI's genuine strengths are breadth and price per watt-hour at the top of its range, where several Elite and Apex units are among the cheapest energy in the whole catalog, alongside unusual hardware like sodium-ion cold-weather units and dual solar-plus-alternator vehicle hubs. Two caveats for this page. The AC60P is not one of the cheap-per-watt-hour models, and BLUETTI's lineup-wide claim of 3,500 to 6,000+ cycles overshoots this particular SKU, whose own rating is 3,000.
Worth knowing
Customer support inconsistency is the #1 risk factor. Older/discontinued units may become unrepairable — no spare parts policy for some models. Some reports of erratic communication from support agents.
Analyst note
The app scores are close enough to be a wash, with EcoFlow at 4.6 on iOS and 4.2 on Android against BLUETTI's 4.5 on both, so choose on hardware rather than software. The real brand split is service: our assessment rates BLUETTI's support the most inconsistent in the space and EcoFlow's as polarized rather than dependable, and neither company will help you once coverage lapses. If the six-year warranty is what's pulling you toward the AC60P, price that coverage at what the claims process behind it is actually worth.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 Classic
The DELTA 3 Classic's record is an early-adopter snapshot rather than field history, and what exists comes from review outlets testing at launch rather than long-term ownersA1A2A3. Wall charging measured just under 55 minutes from emptyA1, idle draw came in around 17WA2, and more than one outlet remarked on how quiet the unit stays for the priceA2A3. One reviewer singled out the front-facing layout, AC and USB on the front with charging inputs at the back, as a return to senseA4.
Two outlets independently flag the solar ceiling, with one noting the display topped out at exactly 500WA5A9. The app and the Storm Guard auto-charge feature draw the most consistent praiseA6A12, and the handle is described as solid and well centeredA11. The one negative worth planning around comes from an aggregated retailer review summary reporting 5-10% self-discharge per month in storageA14. That source is second-hand and worth holding loosely, but if this is your grab-and-go outage box, top it up quarterly and the question goes away.
“In our tests, the DELTA 3 Classic charged from empty to full plugged into a standard wall outlet in just shy of 55 minutes.”

BLUETTI AC60P
The AC60P's field record is thin and almost entirely about the enclosure. IP65 dust and low-pressure-jet resistance on LiFePO4 cells is the headlineB1, compact durability is what the platform gets praised forB4, and Turbo charging is reported at roughly an hour to fullB2. Most of that testing is on the AC60 rather than the AC60P specificallyB2B4, so read it as evidence about the platform rather than proof about this exact unit.
The expandability claim is the one to hold loosely. It traces only to BLUETTI's own product page, with no published field results behind itB3, so treat the growth path as a manufacturer statement rather than something anyone has demonstrated and written up. There is no long-term durability record and no support-experience record for this unit to draw on at all.
“IP65 water- and dust-resistant — protected from dust and low-pressure water jets from any direction — though not fully waterproof; built on LiFePO4 chemistry.”

Who Should Buy Which
Buy the DELTA 3 Classic if you…
- →You need one box that can start something with a motor. 1,800W continuous with 3,600W of surge is a different class of inverter from 600W and 1,200W, and here it's also the cheaper one.
- →You charge from panels and the weather doesn't cooperate. A 500W input ceiling against 200W is the difference between recovering on a mediocre day and watching the state of charge sag.
- →Your CPAP is on it. A 320Wh night leaves 550Wh of the EcoFlow's 870Wh usable in reserve, which is another whole night, and the unit is rated 30dB against the AC60P's 45dB.
- →You simply want the most watt-hours your money will buy. That is this unit, at $469 and $0.46 per watt-hour against $749 and $1.49.
Buy the AC60P if you…
- →The unit lives outdoors. IP65 against dust and low-pressure water jetsB1 is the one thing on this page the EcoFlow has no answer to: job site, boat deck, open truck bed, a tent in real weather.
- →You already run BLUETTI expansion batteries and want a small unit that plugs into hardware you own. Both of these expand, but each only into its own brand's batteries.
- →You want the longest coverage available on a small unit and you'll buy direct. Six years against five, and our brand assessment is clear that buying direct from BLUETTI produces the better support outcomes.
If neither fits
If your real load looks like the big rows on this page, 1,645Wh for an eight-hour blackout or 4,685Wh for a day of van life, close both tabs. The DELTA 3 Classic falls 775Wh and 3,815Wh short of those two, and the AC60P falls further still. You want a bigger class of station with a higher inverter ceiling, and buying either of these first means buying twice.
The Bottom Line
Take the DELTA 3 Classic. It costs $469 against $749, holds twice the energy, runs three times the inverter, accepts more than twice the solar, switches to battery faster and runs quieter, and it carries the same 3,000-cycle rating, so none of that advantage erodes with age. When the cheaper unit wins the price row and the capability rows at the same time, the comparison is finished.
The AC60P's defence is one spec that never appears on the table: an enclosure rated to shrug off dust and a hoseB1. If that describes where you work, it's the right box and the capacity hit is the cost of doing business outdoors. If it doesn't, you're spending the $280 between $749 and $469 on a rating that will spend its life in a closet.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the BLUETTI AC60P worth $280 more than the EcoFlow DELTA 3 Classic?
Only if you need the IP65 shell. At $749 against $469 the AC60P hands you 504Wh instead of 1,024Wh and a 600W inverter instead of 1,800W, so the premium is not buying capability. It's buying an enclosure rated against dust and low-pressure water jets, a lighter carry at 21.2 lb against 26.7 lb, and one more year of warranty. That's a fair trade for someone working outdoors and a poor one for everybody else.
What can the DELTA 3 Classic run that the AC60P can't?
Anything that draws steadily above 600W, which is the AC60P's continuous inverter rating. Its 1,200W figure is surge headroom for the instant a motor starts, not a load you can park there. The DELTA 3 Classic runs 1,800W continuous with 3,600W of surge, and testing found it starts a small window air conditioner without complaint, though the runtime that follows is short.
Which one is better for a CPAP?
The DELTA 3 Classic, comfortably. A CPAP at about 40W for eight hours is 320Wh, which both units cover, but the EcoFlow finishes the night with 550Wh of its 870Wh usable still in the tank while the AC60P finishes with 108Wh of its 428Wh. That is two nights against one. The EcoFlow is also rated 30dB against 45dB, which matters when the box is beside the bed.
How fast do these two recharge?
On AC they're close. Testing measured the DELTA 3 Classic from empty to full in just under 55 minutes on a wall outlet, and BLUETTI's Turbo mode is reported at about an hour. On solar they aren't close at all: the EcoFlow accepts up to 500W against the BLUETTI's 200W, so 1,024Wh at full input is a bit over two hours while 504Wh at 200W is a bit over two and a half. Both of those are rated ceilings, not what a real roof delivers.
Does the AC60P last longer, given BLUETTI's 3,500 to 6,000 cycle claim?
No. BLUETTI advertises 3,500 to 6,000+ cycles across its lineup, but the AC60P's own figure in our data is 3,000, the same rating the DELTA 3 Classic carries. Buy on the SKU's number rather than the lineup's. Because the cycle ratings match, the cheaper unit with the larger battery is also the cheaper unit per lifetime kilowatt-hour, at $0.15 against $0.50.
