EcoFlow DELTA 3 Max vs DJI Power 1000 V2
At $899 the DELTA 3 Max finishes an eight-hour blackout with 96Wh to spare; at $699 the Power 1000 V2 covers about 53% of the same night, and 31.3 lbs against 50.7 is the only argument that survives it.

Spec deltas
The DELTA 3 Max costs $200 more than the Power 1000 V2 ($899 against $699) and holds exactly twice the battery, 2,048Wh against 1,024Wh. Divide that premium by the capacity it buys and each added watt-hour runs about 20 cents ($200 divided by 1,024Wh), less than a third of the 68 cents a watt-hour the DJI charges for the ones it ships with. Read that ratio once and the rest of this page is commentary on it.
Eight hours of blackout load comes to 1,645Wh, and that one row settles the matchup: the DELTA 3 Max covers it with 96Wh left, while the Power 1000 V2 runs out 775Wh short at about 53% of the night. The remote-workday row tells the same story with a narrower gap, 910Wh needed against 870Wh usable, a 40Wh miss. Three of the six scenarios go to the DELTA 3 Max, one is a dead heat, and two are past what either box can do.
The DJI's case is physical and it is real. It weighs 31.3 lbs against 50.7, its USB-C port delivers 140W against 100W, and its inverter is rated 2,600W continuous to the DELTA's 2,400W. If your longest realistic day fits inside 870Wh, take the lighter box. If you already know it doesn't, $200 is a cheap way to stop rationing.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
Because both packs carry the same 4,000-cycle rating, capacity is the only lever on lifetime energy, and the DELTA banks 8,192 kWh over its life against the DJI's 4,096. That prices the energy at 11 cents a lifetime kilowatt-hour against 17. The cheaper sticker is attached to the more expensive battery, and the gap widens every time you cycle it.
DELTA 3 Max: 2,048Wh at $899, which the record puts at $.44 per WhPower 1000 V2: 1,024Wh at $699, which the record puts at $.68 per WhBoth packs are rated for at least 4,000 cycles
Why it mattersIf your budget can stretch $200, stop comparing stickers and compare kilowatt-hours, because that is what you are actually buying.
continuous output
Put the surge ceilings beside that and the DJI's 2,600W reads correctly: it is a starting spec, not a running spec. It will kick a motor over at up to 4,400W and then hand you twenty minutes of it. For a drill, a blender, a circular saw, that is exactly right. For a microwave, a space heater, or a fridge you need to keep cold past lunch, the tank is the binding constraint and the inverter rating never enters the arithmetic.
Power 1000 V2: 2,600W continuous output, 1,024Wh capacity, 870Wh usable after the site's flat 15% allowanceDELTA 3 Max: 2,400W continuous output, 2,048Wh capacity, 1,741Wh usableSurge ceilings: 4,800W for the DELTA 3 Max, 4,400W for the Power 1000 V2
Why it mattersAnyone reading 2,600W as the more powerful unit should read it as starts more, runs shorter, and then check which of those they need.
So the DJI's growth path costs an adapter, a socket and a battery before it draws level with the DELTA's starting point, and our record's 1,200W solar figure for the V2 is contested by a hands-on report of that adapter capping at 600WB6, which means it is not a number to buy on. The DELTA starts at the DJI's expanded position and grows from there.
Both units support their maker's expansion batteries, so neither locks you out of growthThe Power 1000 V2 has only two SDC expansion ports, and an expansion battery plus an MPPT solar accessory fills both, leaving no socket for something like the 12-volt outletB7The Power 1000 V2 has no built-in solar charge controller, so solar runs through a separate proprietary adapter, reported at $329 and passing only 600WB6The DELTA 3 Max is rated for 500W of solar input
Why it mattersIf you plan to add panels or capacity later, start from the unit that is already where the other one is headed.
And only one of the two has a number attached to it. The DJI's blank is not a demerit, since the testers who have actually sat near it describe it as nearly silentB1B2, but a published floor you can hold a manufacturer to is a different kind of assurance than a review you are trusting secondhand, and the EcoFlow adds an app-side quiet mode and a charge-speed limit if the fan does bother youA1A2.
CPAP Overnight needs 320Wh at about 40W for eight hours; the DELTA 3 Max finishes with 1,421Wh spare, the Power 1000 V2 with 550WhThe DELTA 3 Max publishes 30dB, a manufacturer best-case floor rather than a measurementThe Power 1000 V2's noise level is not published at allIndependent testers report the DJI's fan barely audible even charging at 1,400-1,450W, and say the tell that the fans are running is a faint warm smell rather than a soundB1B2
Why it mattersThe CPAP buyer who wants something in writing takes the DELTA; the one who trusts hands-on reports keeps the cheaper, lighter box.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: After the flat 15% usable allowance this site applies to every unit, the gap is 1,741Wh against 870Wh, which is what every other section on this page is downstream of.
continuous output
Nameplate capacity flatters both boxes and the derated figures are what you actually live on: 1,741Wh against 870Wh once the flat 15% allowance is applied. That single subtraction is what turns the Power 1000 V2's remote workday from a pass into a 40Wh miss, and it is why a 1,024Wh unit does not cover a 910Wh day.
There is a second surprise buried in the weights. The DELTA 3 Max carries 2,048Wh across 50.7 lbs, about 40Wh for every pound, while the Power 1000 V2 carries 1,024Wh across 31.3 lbs, about 33. The heavier unit is also the more efficient thing to lift, which is a strange sentence until you remember that you lift it twice a trip and live off it all night.
Your Life, Your Pick
Selected because: Three of the six loads go to the DELTA 3 Max, the CPAP night is a dead heat, and two are beyond both boxes; the row you live in decides this, not the totals.
The DELTA 3 Max wins the blackout by 96Wh, and that number deserves saying out loud before anyone else says it: 96Wh out of 1,741Wh usable is a lamp and a phone, not a cushion. Add one more appliance to that 1,645Wh list and the DELTA is in the same boat the DJI is already in. It wins the row; it does not win it comfortably.
The workday row cuts the other way and is worth reading carefully: the Power 1000 V2's 1,024Wh nameplate clears the 910Wh this scenario asks for, and it is the flat 15% allowance that tips it to a 40Wh shortfall. Trim one small appliance across the day and it finishes. The two rows nobody wins are the honest ones. Van life wants 4,685Wh a day, leaving the DELTA 2,944Wh short and the DJI 3,815Wh short, and even weekend camping's 2,100Wh beats both, though the DELTA covers about 83% of it against the DJI's 41%. One of those is the essentials; the other is the phones.
Portability & Form Factor
Selected because: 31.3 lbs against 50.7 lbs is the DJI's strongest card and the one reason to argue with the verdict.
weight
Nineteen pounds is the difference between a two-hands, bent-knees lift and something you can move with one arm while holding a cooler in the other, and the Power 1000 V2 is on the right side of it at 31.3 lbs against 50.7. Over a tailgate, up basement stairs, in and out of a trunk every weekend, that is a real and repeating advantage, and it is the reason the tailgate row notes weight even while the capacity goes the other way.
The DJI spends a little of that advantage on where it put the handles: one tester found side-positioned handles make one-handed carrying feel unbalanced even at just over 31 lbsB11. If the box lives in a closet and comes out twice a year, weight is a footnote you will forget. If it rides in a trunk most weekends, it is the whole argument.
Lifetime Value
Selected because: Identical 4,000-cycle ratings mean capacity alone sets lifetime energy: 8,192 kWh against 4,096 kWh, or 11 cents a lifetime kilowatt-hour against 17.
cost / lifetime kWh
Eleven cents a lifetime kilowatt-hour against seventeen. Both packs carry the same at-least-4,000-cycle rating, so capacity is the only thing setting that gap, and it compounds in the direction you would expect: 8,192 kWh of lifetime energy against 4,096 kWh. Cycle either unit hard enough to care about cost per unit of energy and the $200 has already paid itself back.
Warranty is where the comparison stops rather than tilts. EcoFlow lists up to five years, subject to the usual registration conditions, which prices out at $180 a covered year ($899 across 5 years). DJI's term is simply not in our record for this model, so it is unrecorded rather than absent, and there is nothing to price against. Confirm it at the point of sale rather than assuming either direction.
What the Specs Don't Tell You
Selected because: Two flags fire here: the DELTA's 4,800W surge ceiling against 4,400W, and the fact that the Power 1000 V2 publishes no noise figure at all.
The DELTA 3 Max has both the taller surge ceiling and the better ratio, 4,800W at 2x its continuous rating against 4,400W at 1.7x, and the ratio is the less useful half of that. What decides whether your fridge or your compressor actually starts is the absolute ceiling, and 4,400W is a published ceiling, not a gap in the data. Check the startup draw of the heaviest motor you own against that figure instead of assuming it trips.
The noise flag is the opposite shape: it fires because there is nothing there. The DELTA 3 Max publishes 30dB and the Power 1000 V2 publishes nothing, which is a missing number rather than a bad one. Treat it as a question to answer before you commit to a bedroom or an apartment, not as a verdict already delivered.

Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Neither box covers a full 2,100Wh weekend, so the question is what gets left out. The DELTA 3 Max reaches about 83% of the list and comes up 359Wh short; the Power 1000 V2 reaches 41% and is 1,230Wh short. One of those is a weekend with the cooler running and the string lights off, the other is phones, a fan and an early night.

DELTA 3 Max
The DELTA 3 Max finishes the night and it finishes by 96Wh, which is a lamp and a phone rather than a cushion. The Power 1000 V2 stops 775Wh short of the 1,645Wh this load needs, a little past the halfway mark, which in practice means waking up to a warm fridge. If your own list is longer than this one, read the DELTA's win as a pass rather than a comfortable one.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Eight hours at about 40W comes to 320Wh, so both boxes coast through the night with most of the tank untouched and capacity decides nothing. What decides it is the fan running a few feet from your pillow, and only the DELTA 3 Max publishes a figure there, 30dB, and even that is a manufacturer best-case floor rather than a measured result. Quiet is DJI's reputation across the line, and the Power 1000 V2 is the model where that reputation has no published number behind it, so this row comes down to price, weight, and whether you will buy a fan you have not heard.

DELTA 3 Max
The Power 1000 V2 loses this one by 40Wh, which is worth understanding before you hold it against the unit. Its 1,024Wh nameplate clears the 910Wh workday outright; it is the flat 15% usable allowance, applied to every unit on this site, that pulls it to 870Wh and under the line. Trim one small appliance across the day and it finishes. The DELTA 3 Max simply does not raise the question, ending the day with 831Wh still in hand.

DELTA 3 Max
Both handle game day; the DELTA 3 Max keeps more in reserve (38% used vs 77%). Tailgating is a light load, though, so the number you'll feel is weight: 31.3 lbs for the Power 1000 V2 against 50.7 lbs for the DELTA 3 Max, from the trunk to the setup spot.

Conclusion
September 13, 2026
Verdict: the EcoFlow DELTA 3 Max
Buy the DELTA 3 Max. It costs $200 more than the Power 1000 V2 ($899 against $699) and holds exactly twice the battery, 2,048Wh against 1,024Wh, which works out to about 20 cents for every watt-hour you add ($200 divided by 1,024Wh) against the 68 cents a watt-hour the DJI charges for the ones already in the box. That extra kilowatt-hour is not abstract: it is the difference between covering an 8-hour blackout's 1,645Wh and stopping 775Wh short of it, and between finishing a remote workday and missing by 40Wh. The DJI earns its two genuine wins honestly, 31.3 lbs against 50.7 and a 140W USB-C port against 100W, so if every load you care about fits inside 870Wh of usable capacity, the lighter box is the better buy and you should take it without guilt. Most people reading a blackout comparison do not have loads that small.

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 rates 4.2/5 (52nd percentile of 26 Large-class units), and Power 1000 V2 rates 4.9/5 (92nd 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.
Surge: the ceiling decides, not the ratio
The DELTA 3 Max has the taller ceiling and the better ratio, 4,800W at 2x its 2,400W continuous rating against the Power 1000 V2's 4,400W at 1.7x, and the ratio is the less useful half of that pair. Motors briefly pull two to three times their running draw, so what determines whether your fridge or compressor actually starts is the absolute number it has to clear, and 4,400W is a published ceiling rather than a hole in the spec sheet. Look up the startup draw of the heaviest thing you own and check it against both figures instead of reasoning from the multiple.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The Power 1000 V2's figure is a maximum rather than a guarantee — it depends on buying from DJI's own store, which is where the full five years is advertised. Worth saying because the per-dollar framing can suggest otherwise: the Power 1000 V2 works out at 7.2 years of cover per $1,000 spent against the DELTA 3 Max's 5.6, but that spread is the price gap, not the terms.
The Power 1000 V2's fan has no number
This flag fires on an absence, not a fault. The DELTA 3 Max publishes 30dB and the Power 1000 V2 publishes nothing, and a missing figure is not a loud one. Note also that the DELTA's 30dB is a manufacturer best-case floor, the sort of number a quiet mode produces at low load, not a measurement you should expect while it charges at full speed. Quiet is DJI's reputation across its power line, and this is the model that reputation has no published figure for, so if the unit is going in a bedroom or an apartment, go find hands-on accounts before you commit rather than reading either number as settled.

Analyst note
The Power 1000 V2 is cheaper to buy, but the DELTA 3 Max is cheaper to own. At $0.11/kWh over its lifetime vs $0.17/kWh, the DELTA 3 Max's higher cycle life and capacity make each dollar go further over the years. 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.
Brand trust
EcoFlow
Ecosystem
The deepest catalogue in portable power, 12 to 15 models across DELTA Pro, DELTA 3 and RIVER 3, plus panels and smart home panels, which matters mainly because the expansion battery you might want in two years will still be on sale.
Support
US phone, email and chat support, with experiences that split hard: prepaid-label replacements that arrive painlessly for some buyers, long waits and refurbished units on new claims for others. Buying through Costco or Amazon gives you a second return path that does not depend on which of those you get.
Community
The largest owner community in the category, around 31,000 members on r/Ecoflow_community plus Facebook groups and an official forum, which is where the answer to your specific wiring question already exists.
App experience
Rated 4.6/5 iOS (~8,400 ratings) · 4.2/5 Android (~17,000 ratings)
Unique strength
X-Stream fast charging and the fastest innovation cadence in the category, with app control rated 4.6 on iOS and 4.2 on Android.
Worth knowing
EcoFlow tested subscription paywalls for advanced app features in early 2025 and paused the plan after backlash, and it offers no parts or service once the warranty is up. Plan on the box being disposable at end of life.
DJI
Ecosystem
A 2024 entrant with five models so far, and a real naming trap: the original Power 1000 is still sold alongside the V2, so check which revision a Power 1000 listing actually ships before you buy.
Support
DJI's global service network from the drone business carries a good reputation, but almost none of that track record is power-station-specific yet.
Community
No dedicated power station community. Questions land in r/dji among roughly 250,000 mostly drone users, so expect to be the first person asking yours.
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
Premium build, 700-plus battery patents from drone R&D, and SDC ports that fast-charge DJI gear, which is a genuine advantage if you already own some. Wall charging is quick, about 56 minutes on this model specifically rather than across the line.
Worth knowing
There is no built-in solar charge controller, so solar requires a separate proprietary adapter, and expansion exists on the Power 1000 V2 and Power 2000 but not the earlier Power 1000 or Power 500. The app scores 3.5 on both stores, though that rating covers DJI's whole ecosystem, and the on-device screen is reported as the more reliable interface. The warranty term for this model is not in our record, so get it in writing at purchase.
Analyst note
EcoFlow brings the history, the community and the parts catalogue; DJI brings hardware pedigree from a different product category and a record that is six months deep on this one. Neither of those should decide this purchase. The capacity gap already did, and brand only matters here for the two things the DJI record leaves blank: its warranty term and its noise figure.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3 Max
Field data on the DELTA 3 Max is thinner than the DJI's and it comes from hands-on review sites rather than long-term owner threads, with some sources conflating the Max and the Max Plus, so trust the line-wide claims further than the variant-specific onesA0. What does exist is consistent on the fan: essentially silent at conversational distance under moderate load, rising under heavy load but staying quieter than most of the 2kWh class, with an app-side quiet mode and a custom charge-speed limit if it bothers youA1A2.
The most useful entry is the durability one. Capacity held steady between a one-month and a three-month test, within measurement error, and the unit came through truck-bed transport, storage in a roughly 105 degree garage, and operation near freezing at about 34 degrees without complaintA3. Reviewers call the combination of fast recharge and LFP longevity one of the better value propositions in the segmentA4. None of that is a decade of owner historyA0, but it is the right kind of evidence for a unit you expect to sit in a garage until you need it.
“Whisper-quiet under moderate load — essentially silent at conversational distance; the app adds a low-power quiet mode and a custom charge-speed limit if fan noise bothers you. Fans rise under heavy load but stay quieter than most competitors in the 2kWh class.”

DJI Power 1000 V2
The Power 1000 V2 has roughly six months of independent hands-on coverage across five outlets, and no organic owner-forum threads turned up for the V2 specifically, so read all of this as expert-tester field reports rather than crowd sentimentB0. The standout is quiet: the fan barely registers even at full charging speed around 1,400 to 1,450W, and two testers separately noticed that the tell the fans have spun up is a faint warm plasticky smell rather than a sound, with app-reported internal temperatures normalB1B2. Build quality draws the same kind of praise, described as premium enough not to look out of place in a studioB3, and the 10ms switchover is credited as twice as fast as the original Power 1000 and genuinely suited to a home officeB9.
The complaints are all about the things bolted to the outside. The non-standard C19 charging cable is the kind you will not have a spare of when it disappearsB5. Solar runs through a proprietary adapter reported at $329 and passing only 600W, which is hard to justify once panels are addedB6, and with only two SDC sockets an expansion battery plus a solar accessory leaves nothing for the 12-volt outletB7. The one that would change a purchase: idle draw measured around 18W, enough to empty the pack in about two and a half days sitting connected with nothing else runningB8. Wall recharge, on the other hand, is genuinely fast at about 56 minutes empty to fullB4.
“The fan barely makes a sound even during full-speed charging around 1,400-1,450W — one of the quietest power stations in its class, nearly silent under normal loads.”

- Charging is dramatically faster than the original Power 1000, but real-world charging setups bring their own friction: a non-standard AC cable and, for solar, an expensive proprietary adapter with limited throughput. [Power 1000 V2 · 3 entries]
- The two shared SDC expansion ports are a recurring bottleneck — using them for an expansion battery or solar accessory can leave no capacity for other add-ons. [Power 1000 V2 · 2 entries]
- UPS switchover speed and overall build quality are the two things independent reviewers most directly credit as concrete improvements over the original Power 1000. [Power 1000 V2 · 2 entries]

“Whisper-quiet under moderate load — essentially silent at conversational distance; the app adds a low-power quiet mode and a custom charge-speed limit if fan noise bothers you. Fans rise under heavy load but stay quieter than most competitors in the 2kWh class.”

“The EcoFlow app is one of the main reasons people migrate to the ecosystem: deep control including a custom charge-speed limit and quiet mode, well beyond the on-device interface.”

“It's easier to notice when the fans are on by a faint, warm, plasticky smell rather than by sound; a separate reviewer likewise noted an unusual electronics smell on first use but confirmed via the app that internal temperature stayed normal.”

“Solar charging is where things get a little odd: the $329 adapter only allows 600W of solar input despite '1.8kW' branding on the box; pairing solar panels with the adapter runs close to $1,000, which is extremely difficult to justify.”

“You only get two SDC expansion ports, and if both are occupied (e.g. an expansion battery plus an MPPT solar accessory) that leaves no spare socket for something like the 12-volt cigarette outlet — described as really odd and potentially annoying in real-world use.”

Who Should Buy Which
Buy the DELTA 3 Max if you…
- →The person planning for the evening the grid drops: a fridge, a couple of lamps, the router and the phones comes to 1,645Wh over eight hours, and the DELTA 3 Max is the only one of these two that reaches morning.
- →The remote worker who bills by the day and cannot lose the afternoon. A 910Wh workday leaves 831Wh in reserve, so a long call or an extra monitor does not require arithmetic.
- →The buyer who wants the quiet claim in writing rather than in a review, and the app-side quiet mode and charge-speed limit that go with itA1A2.
- →Anyone who expects their load list to grow, since 2,048Wh is where the DJI's expansion path is trying to get to.
Buy the Power 1000 V2 if you…
- →The tailgater and the trunk-to-table crowd. A 670Wh game day leaves 200Wh spare and 31.3 lbs is the number your back registers, not the capacity.
- →The drone or camera owner already inside DJI's ecosystem, where the SDC ports and a 56-minute wall rechargeB4 are worth real money on a shoot day.
- →The USB-C-first worker whose laptop wants 140W and who almost never touches the AC outlets.
- →The CPAP user on a budget whose night costs 320Wh, leaving 550Wh spare, and who is comfortable taking the fan on the word of testers rather than a spec sheetB1.
If neither fits
Skip both if you are living in a van or running a house. Van life's 4,685Wh a day leaves the DELTA 2,944Wh short and the DJI 3,815Wh short, and even a full weekend camping list of 2,100Wh beats both boxes. You want a substantially larger station with real expansion, or a proper house-battery and inverter install, not the larger of two units that both fall short.
The Bottom Line
Take the DELTA 3 Max. The $200 between them ($899 against $699) buys a second full kilowatt-hour at about 20 cents a watt-hour ($200 divided by 1,024Wh), against the 68 cents a watt-hour the DJI charges for its first, and because both packs share the same at-least-4,000-cycle rating, that capacity is the only thing standing between 11 cents and 17 cents per lifetime kilowatt-hour. Every scenario on this page is a restatement of the same purchase.
The Power 1000 V2 is not the wrong unit, it is the smaller one, and 31.3 lbs against 50.7 is a real reason to choose it if your loads are honestly tailgate-sized. But the DELTA's blackout win by 96Wh should tell you something about the shape of this category: even the bigger box here is not generous. Buy the one with the margin, and spend the afternoon you saved not doing this arithmetic again.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DJI Power 1000 V2 enough for an 8-hour power outage?
Not for a full one. An 8-hour blackout list of 1,645Wh against 870Wh of usable capacity leaves it 775Wh short, about 53% of the night covered. The DELTA 3 Max does finish it, though only by 96Wh, so if your outage list is longer than the standard fridge-plus-lights load you should be shopping above both of these.
Why is the cheaper DJI the more expensive power station?
Because you pay for energy, not for boxes. The Power 1000 V2 works out to 68 cents per watt-hour against the DELTA 3 Max's 44, and since both packs are rated for at least 4,000 cycles, the DELTA's larger battery banks 8,192 lifetime kWh against 4,096. That is 11 cents a lifetime kilowatt-hour against 17.
Which one is quieter, the DELTA 3 Max or the Power 1000 V2?
There is no honest way to compare them on paper. The DELTA 3 Max publishes 30dB, which is a manufacturer best-case floor rather than a measurement, and the Power 1000 V2 publishes no figure at all. Independent testers who have used the DJI describe the fan as barely audible even while it charges at 1,400 to 1,450W, so the blank is a gap in the documentation and not evidence that it is loud.
What warranty does the DJI Power 1000 V2 come with?
Our record does not carry a term for this model, so treat it as unrecorded and confirm it in writing before you buy. EcoFlow lists up to five years on the DELTA 3 Max, typically conditional on registration, which works out to $180 per covered year across its $899 price. If warranty length is one of your deciding factors, get DJI's answer from the retailer first.
Can either of these start a refrigerator?
Both should. Fridge and AC compressors briefly pull two to three times their running draw, and the DELTA 3 Max surges to 4,800W (2x its 2,400W continuous) while the Power 1000 V2 surges to 4,400W (1.7x its 2,600W). Check your compressor's startup draw against those ceilings rather than the ratios. The harder question is how long you run it afterwards, and that is a capacity question the DELTA wins outright.
