Spec deltas
The bigger battery here is also the cheaper one by the kilowatt-hour. BLUETTI's Elite 320 holds 3,200Wh to the EcoFlow DELTA 3's 1,024Wh, yet it prices out at $0.34 per watt-hour against the DELTA 3's $0.61. Pay more at the register, pay less per unit of energy. That inversion settles most of this page.
The catch is that per-watt-hour value only cashes out if you spend the watt-hours. Both packs are rated for 3,000 cycles, so if your typical draw fits inside the DELTA 3's 1,024Wh, the Elite's extra 2,176Wh just sits there, and you spent $471 more for headroom you never touch. The DELTA 3 is also 48 pounds lighter and starts motor loads with more room to spare. This is less which is better than which is your size.
So the verdict splits cleanly by mission. If you're buying a power station to cover a weekend, an outage, or a fridge for two days, take the Elite 320: it's the only one of the two that actually finishes those jobs, and it costs less per kilowatt-hour doing them. Buy the DELTA 3 if you'll carry it more than you'll lean on it, and your loads stay under 1kWh. Neither answer is wrong, but they're answers to different questions.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
But that only lands if you use the capacity. Cycle life is fixed at 3,000 for both, so a buyer whose loads fit inside 1kWh cycles the DELTA 3 exactly as often and never draws on the Elite's top two-thirds. For that person the per-kilowatt-hour math is a mirage, and the $629 sticker is the real number.
Elite 320: $1,100 for 3,200Wh = $0.34/Wh; DELTA 3: $629 for 1,024Wh = $0.61/WhCost per lifetime kWh: Elite 320 $0.11 (9,600 kWh over life), DELTA 3 $0.20 (3,072 kWh)Both packs rated for 3,000 cycles
Why it mattersIf your regular draw fits under a kilowatt-hour, the DELTA 3's lower price is the truer economy; if you routinely need more, the Elite is cheaper every way that counts.
solar input
These aren't close calls you trim your way out of. A weekend and a grid-down night are the exact missions a 3.2kWh unit is built for, and the DELTA 3 simply isn't that unit. The Elite compounds the lead off-grid: 1,000W of solar input, double the DELTA 3's 500W, refills a day's use in a morning instead of an afternoon.
DELTA 3 usable ~870Wh (1,024Wh less a flat 15% conversion allowance); Elite 320 usable ~2,720WhWeekend Camping needs 2,100Wh; 8-Hour Blackout needs 1,645WhSolar input: Elite 320 1,000W vs DELTA 3 500W
Why it mattersAnyone buying for camping past a single night or for real backup should skip the DELTA 3 on capacity alone.
Both run the same 1,800W steady, so for resistive loads they're twins. But when a compressor or a pump kicks and briefly pulls two to three times its rating, the DELTA 3 has more headroom before it trips. Capacity does nothing for you at that instant; startup headroom does, and here the little box has more of it.
DELTA 3 surge 3,600W (2x its 1,800W continuous); Elite 320 surge 2,700W (1.5x)Both units run 1,800W continuousFridges, pumps, and power tools briefly draw 2-3x their rated wattage at startup
Why it mattersIf your must-run load is a full-size fridge, a well pump, or a power tool, the DELTA 3 is the safer starter despite being the smaller unit.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The Elite 320 works out to $0.34 per watt-hour against the DELTA 3's $0.61, so the pricier unit is the cheaper energy, and that inversion frames the whole comparison.
cost / lifetime kWh
Two ways to price a battery, and they disagree on the sticker but agree on the substance. At the register the DELTA 3 is $471 cheaper. By the energy you'll draw over 3,000 cycles, the Elite 320 is the bargain: eleven cents per lifetime kilowatt-hour against the DELTA 3's twenty. Read that once and you've got the whole cost story. The Elite delivers 9,600 kilowatt-hours across its life to the DELTA 3's 3,072, and a bigger pack spreads its price thinner.
The trap is assuming you'll spend all of it. Cycle life is fixed at 3,000 for both, so a buyer whose loads fit inside 1kWh cycles the DELTA 3 just as often and never touches the Elite's top two-thirds. For that person the per-kilowatt-hour advantage is a number on paper and the $629 price is the one that matters. The Elite's value is earned, not automatic. It shows up only when the capacity gets used.
Your Life, Your Pick
Selected because: Capacity decides five of six test loads: the DELTA 3's 870Wh usable covers a CPAP and a tailgate but falls short of a weekend (2,100Wh) or an 8-hour blackout (1,645Wh).
Capacity, not cleverness, settles five of the six scenarios. The DELTA 3's 870Wh of usable energy, its 1,024Wh nameplate less a flat 15% conversion allowance, covers a CPAP night and a tailgate and then runs out. A weekend campout at 2,100Wh leaves it 1,230Wh short. An 8-hour blackout at 1,645Wh leaves it 775Wh short. The Elite's 2,720Wh finishes both and keeps going.
The remote workday is the one honest near-miss. The DELTA 3 needs 910Wh and has 870 usable, a 40Wh gap its 1,024Wh nameplate actually clears; the flat derate is what tips it under. Skip one small load across the day and it makes it. But squeaks past it and covers it with 1,810Wh to spare are different purchases, and the second one is the Elite.
Portability & Form Factor
Selected because: 27 pounds against 75 is the DELTA 3's clearest win, the gap between a one-hand carry and a roll-only unit.
weight
Here the DELTA 3 wins outright, and it isn't close. Twenty-seven pounds is a one-hand lift into a trunk. Seventy-five is a two-person, bent-knee job, which is why BLUETTI built the Elite to roll instead of be carried: it rides on oversized shock-absorbing wheels with a telescoping handleB2. On flat pavement that 48-pound gap mostly disappears.
So the weight question isn't how heavy, it's heavy where. If your power lives in one spot and moves on level ground, the Elite's wheels erase most of the difference and you should ignore the number. If it goes up trailheads, into truck beds, and down basement stairs, the 48 pounds is the entire story and the DELTA 3 is the only sane pick.
What the Specs Don't Tell You
Selected because: The counters that don't show in the headline specs: the DELTA 3's larger 3,600W surge, and the Elite's unpublished noise level and sealed capacity.
rated cycles
One catch runs in the DELTA 3's favor, and it's counterintuitive: the smaller unit has the bigger surge. Its inverter peaks at 3,600W, double its 1,800W continuous, against the Elite's 2,700W at 1.5x. Both run the same 1,800W steady, so for a space heater or a kettle they're identical. But when a fridge compressor kicks and briefly pulls two to three times its rating, the DELTA 3 has 900W more room before it stumbles.
Two catches point the other way, both at the Elite. It's the one with no published noise figure, which isn't proof it's loud but leaves nothing to hold it to if it's going in a bedroom. And its 3,200Wh is sealed, with no expansion port. That last one barely stings here, because the Elite already starts larger than the DELTA 3 could reach with its first expansion battery, so a first pack on the DELTA 3 mostly buys back capacity the Elite includes out of the box. Only the buyer who'll genuinely blow past 3,200Wh should care that one grows and one doesn't. Warranty is a wash: five years on both, so the per-dollar coverage framing is just the price gap wearing a disguise.

Scenario verdicts
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
Elite 320
Two thousand one hundred watt-hours over a weekend is exactly the load a 3,200Wh unit is built for and a 1,024Wh one isn't. The Elite 320 covers it with 620Wh in reserve. The DELTA 3 taps out around the 41% mark, 1,230Wh short, which means a dead battery sometime Saturday night. This is the scenario that most cleanly separates them: if your trips run past a single night, capacity isn't a luxury, it's the spec.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Elite 320
The DELTA 3 doesn't finish — 870Wh usable against the 1,645Wh this needs leaves it 775Wh short, about 53% of the scenario covered. The Elite 320 covers it with 1,075Wh to spare.

SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP draws about 40W, so over a full night it's a rounding error against either battery. The DELTA 3 ends the night around 63% full and the Elite is barely touched. Capacity decides nothing here, so the real tiebreakers are weight and price: the DELTA 3 is 48 pounds lighter to set on a nightstand, and cheaper. Both run the machine till morning without blinking, so pick on the things you'll notice at 2 a.m.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h

Elite 320
The DELTA 3 comes up just short — it needs 910Wh and has 870Wh usable, a 40Wh gap (its nameplate 1,024Wh actually clears this — the flat 15% conversion allowance is what tips it under). Trim that much — one small appliance's worth across the day — and it finishes. The Elite 320 covers it outright with 1,810Wh to spare.

Game day power for the crew
Elite 320
Both handle game day; the Elite 320 keeps more in reserve (25% used vs 77%). Tailgating is a light load, though, so the number you'll feel is weight: 27 lbs for the DELTA 3 against 75 lbs for the Elite 320, from the trunk to the setup spot.

Neither unit
Neither unit covers this scenario's 4,685Wh: the DELTA 3 comes up 3,815Wh short (about 19% covered), the Elite 320 1,965Wh (58%). 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 30, 2026
Verdict: the BLUETTI Elite 320
Buy the Elite 320 unless portability or up-front budget rules it out. It stores three times the energy (3,200Wh against 1,024Wh), works out to $0.34 per watt-hour to the DELTA 3's $0.61, and is the only one of the two that finishes a weekend, an 8-hour blackout, or a remote workday without running dry. It also refills twice as fast from the sun, with 1,000W of solar input against 500W. The DELTA 3 wins on the two things a spec sheet under-weights: it's 48 pounds lighter (27 against 75), and its 3,600W surge starts big motors the Elite's 2,700W might trip. If your loads live under a kilowatt-hour and you'll carry the unit more than you park it, that's your box, and you'll spend $471 less. Everyone buying for real capacity: the Elite.

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 rates 4.7/5 (80th percentile of 26 Everyday-class units), and Elite 320 rates 4.0/5 (42nd percentile of 25 Large-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Elite 320: 75 lbs Is a Commitment
At 75 lbs, this is manageable but not fun to carry. That's heavier than a large checked suitcase. Moving it from your car to a campsite requires some effort and flat terrain.
Elite 320: Fixed Capacity
The Elite 320 is sealed at 3,200Wh — a complete unit, and already larger than the DELTA 3's 1,024Wh. By contrast the DELTA 3 can add expansion batteries, but that only pulls ahead if you'd grow past 3,200Wh.
Surge Power: Inverter Quality Indicator
The DELTA 3 has a 2× surge-to-continuous ratio vs the Elite 320's 1.5×, and the higher absolute ceiling with it — 3,600W against 2,700W. A higher ratio (≥2×) means the inverter absorbs motor startup surges better, which matters for fridges, AC compressors, and power tools that briefly draw 2-3× their rated wattage. With both measures pointing the same way, the Elite 320 is the one more likely to trip when starting these appliances.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. Worth saying because the per-dollar framing can suggest otherwise: the DELTA 3 works out at 9.1 years of cover per $1,000 spent against the Elite 320's 4.5, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The DELTA 3 is rated for 4,000 cycles vs 3,000. In real life: at daily use, that's 11 vs 8.2 years. At weekend use (twice a week), it's 38 vs 29 years. One caution reading years across different sizes: a cycle is 1,024Wh on the DELTA 3 and 3,200Wh on the Elite 320, so count lifetime energy — roughly 4,096 kWh against 9,600 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.
The Elite's Missing Number
The DELTA 3 says 30 decibels. The Elite 320 says nothing. That isn't the same as saying it's loud; it means there's no figure to hold it to and no way to compare the two on paper. For a garage or a job site, shrug. For a bedroom, a nursery, or a CPAP eighteen inches from your head, the absence is the point, because you'd be buying a sound you haven't heard. Treat the DELTA 3's 30dB as a spec-sheet floor rather than a measurement, but at least it's on the table.

Analyst note
The DELTA 3 is cheaper to buy, but the Elite 320 is cheaper to own. At $0.11/kWh over its lifetime vs $0.13/kWh, the Elite 320's higher cycle life and capacity make each dollar go further over the years. One caution on the lifespan row: the DELTA 3 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the Elite 320 still delivers more over its shorter horizon (9,600 vs 4,096 kWh). Years measure wear, not usefulness.
Brand trust
EcoFlow
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-based phone, email, and chat. Experiences split hard: plenty of hassle-free, prepaid-label replacements, but a vein of complaints about long waits and refurbished units sent against new claims. Buying through Costco or Amazon hands you a stronger return backstop.
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
The deepest ecosystem in portable power and the fastest charging in it. X-Stream refills the base unit quickly, and the DELTA and RIVER lineups give you a clear upgrade ladder if you stay in the family.
Worth knowing
EcoFlow floated a subscription paywall for advanced app features in early 2025 and paused it after backlash. And there's no out-of-warranty service, so once coverage lapses a failure is yours to solve.
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 record in the space: heavily email-based with China-timezone delays, and outcomes that swing from smooth to weeks of runaround. Buying direct from BLUETTI rather than a marketplace reseller tends to go better.
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
Some of the best capacity-per-dollar in the category, and the Elite tier is where that shows, alongside the widest catalog in the space, from sodium-ion cold-weather units to dual solar-and-alternator vehicle hubs.
Worth knowing
Support inconsistency is the single biggest risk here, and some older units have gone unrepairable for lack of spare parts. On a station you're buying as backup insurance, weigh how it's supported, not just how it's spec'd.
Analyst note
Both make excellent apps and neither support operation is bulletproof. The difference is in shape: EcoFlow's is polarized but US-based and reachable by phone, while BLUETTI's is slower and email-bound but improves markedly if you buy direct. Since the Elite 320 is the pricier unit you'd lean on in an outage, its support question is the one to price in, and buying it straight from BLUETTI is the cheapest insurance against the runaround.
Growth path
DELTA 3
EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 1,024Wh.
Accepts up to 500W of solar. Suitable for a 1-2 panel setup.
Generous port selection supports complex multi-device setups.
Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.
Elite 320
FIXED CAPACITYFixed at 3,200Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.
Accepts up to 1,000W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Don't read the DELTA 3's expandability as a straight win here: it starts at 1,024Wh, below the Elite 320's 3,200Wh, so a first expansion battery largely buys back capacity the Elite 320 already includes. It only pulls ahead if you'd grow past 3,200Wh — short of that, the Elite 320's larger fixed capacity is the simpler value.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow DELTA 3
Field data on the standard DELTA 3 is still thin. Most published testing covers its Plus, Max, and Ultra siblings, which differ in capacity and, on the Plus, in fan behavior, so treat sentiment here as preliminaryA0. What is specific to this model is encouraging on the axis that matters for quiet rooms: reviewers found the fans stay off entirely under 200W and are only barely audible from three feet at 500 to 800W, effectively silent at the loads a CPAP or a laptop pullsA1. Its UPS switchover is rated at 10ms, and hands-on testing of a sibling on the same spec saw routers and fridges ride through a cut cleanly, worth noting for character even though we can't pin that particular test to this exact SKUA2.
“At low loads (under 200W) the fans often stay completely off, making the Delta 3 effectively silent; under moderate load (500–800W) the fans are barely audible from three feet away.”

BLUETTI Elite 320
The Elite 320 is new, a CES 2026 launch, so what exists is press and early review coverage rather than long-term owner reportsB0B1. The consistent picture from that coverage is a genuine home-backup unit: reviewers clocked over 66 hours of refrigeration and roughly two days of essential household power from the 3,200Wh pack, across four AC outlets and two USB-C ports at 140W and 100WB3. On moving it, the notes are reassuring for the weight. It's about 75 lbs but rides on oversized shock-absorbing wheels with a telescoping handle, meant to roll around the house rather than be hauledB2. Long-term reliability and support are the questions time hasn't answered yet.

- →Buy it if your must-run load is a big fridge, a pump, or a power tool. Its 3,600W surge starts stubborn motors with more headroom than the Elite's 2,700W.
- →Buy it if $629 is the budget and your draw lives under a kilowatt-hour. You'll spend $471 less for a unit that covers a CPAP night, a tailgate, or a light workday just fine.
Buy the Elite 320 if you…
- →Buy the Elite 320 for backup you'll actually lean on: a grid-down weekend, a fridge and a few lights for two daysB3, a CPAP plus a coffee maker without watching the percentage.
- →Buy it if you solar-charge. Its 1,000W of input refills a day's use in a morning, twice what the DELTA 3 takes in.
- →Buy it if you want the most watt-hours per dollar and you'll stay put. It rolls on its own wheelsB2, so 75 pounds on flat ground is a non-issue.
If neither fits
If your day genuinely needs 4 to 5kWh, like full van life or a whole-house tie-in, neither unit finishes: the Elite covers a little over half a van-life day (58%) and the DELTA 3 under a fifth (19%). Look at a 5kWh-plus station or a two-battery system instead.
The Bottom Line
The Elite 320 is the bigger unit and the cheaper one per kilowatt-hour, eleven cents of lifetime energy against the DELTA 3's twenty, with three times the capacity to spend it on. It finishes the weekend, the blackout, and the workday the DELTA 3 runs dry on, and it refills twice as fast from the sun. If you're buying a power station to lean on, that's the one.
But the value only lands if you use the capacity, and the DELTA 3 makes the honest counter-argument: 27 pounds to the Elite's 75, $471 less at the register, and more surge to start a stubborn fridge. If your loads live under a kilowatt-hour and you carry your power more than you park it, buy the light one and don't look back. Everyone else, the person planning for the outage, the weekend, the two-day fridge, buys the Elite.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the BLUETTI Elite 320 worth almost double the EcoFlow DELTA 3?
If you need the capacity, yes. It holds 3,200Wh to the DELTA 3's 1,024Wh, and it's cheaper per watt-hour ($0.34 vs $0.61) and per lifetime kilowatt-hour ($0.11 vs $0.20). If your loads fit under a kilowatt-hour, you're paying $471 for headroom you won't use, and the DELTA 3 is the smarter spend.
Can the EcoFlow DELTA 3 run a fridge during a power outage?
It will start one; its 3,600W surge handles the compressor kick better than the Elite's 2,700W. But its 870Wh of usable energy covers only about half an 8-hour blackout's typical load. For a full outage you want the Elite's 2,720Wh usable, which reviewers put at over 66 hours of refrigeration.
Which is quieter for CPAP use, the DELTA 3 or the Elite 320?
The DELTA 3 publishes a 30dB floor, and reviewers report its fans stay off under 200W, effectively silent at CPAP draw. BLUETTI doesn't publish a noise figure for the Elite 320, so there's nothing to hold it to. Both easily power a CPAP all night; only the DELTA 3 lets you check the spec before you buy.
How much does the BLUETTI Elite 320 weigh, and can one person move it?
About 75 pounds, but it ships with oversized shock-absorbing wheels and a telescoping handle, so one person rolls it on flat ground. Stairs and loose grass are where the weight bites. The DELTA 3 is 27 pounds, a normal one-hand carry.
Do I actually need the DELTA 3's expandability?
Probably not against this rival. Its first expansion battery mostly buys back capacity the Elite 320 already includes at 3,200Wh, so expandability only pays off if you'd grow past that. If you know you're headed there, the DELTA 3 is a starting point; if not, the Elite's fixed 3,200Wh is the simpler value.
