Head-to-head test
EcoFlow DELTA 3 Ultra vs BLUETTI Elite 320
Every real-world scenario is a near-tie, so this comparison isn't about capacity — it's about which unit still has headroom left when the fridge compressor kicks on, and that's the DELTA 3 Ultra by a full class.

Spec deltas
Run the six scenarios this site models and the DELTA 3 Ultra and Elite 320 tie or come within a few points of each other on five of them — this is not a capacity fight. Both hold roughly the same tank: 3,072Wh for the DELTA 3 Ultra, 3,200Wh for the Elite 320.
What actually separates them is everything around that number. The DELTA 3 Ultra pushes 3,600W continuous against the Elite 320's 1,800W — literally double — and backs it with a 7,200W surge against 2,700W. It also rates for 4,000 charge cycles against 3,000, and publishes a 30dB noise figure where the Elite 320's spec sheet is silent on the subject entirely.
None of that is free: the DELTA 3 Ultra costs $200 more, at $1,199 against $999. For buyers who never approach either unit's power ceiling, that $200 doesn't buy much. For anyone starting a real compressor load, it buys the difference between running and tripping.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Fridge and AC compressors routinely surge 2-3x their rated draw at startup. A 900W compressor fridge that needs a brief 2,000-2,500W kick to start could sit comfortably inside the DELTA 3 Ultra's continuous band, while asking the Elite 320 to absorb the same surge on top of its own running load.
DELTA 3 Ultra: 3,600W continuous output, 7,200W surgeElite 320: 1,800W continuous output, 2,700W surge
Why it mattersAnyone planning to start a fridge, window AC, or power tool off either unit should size against the Elite 320's 2,700W surge ceiling specifically — it's the tighter number on this page by a wide margin.
rated cycles
That extra cycle life is exactly why the DELTA 3 Ultra edges out the Elite 320 on cost per lifetime kWh despite its $200 higher sticker price and $40 higher cost per warranty year. More cycles spread the purchase price over more total energy delivered.
DELTA 3 Ultra: 4,000 rated cyclesElite 320: 3,000 rated cycles
Why it mattersBuyers optimizing for total dollars spent per kWh over a decade of ownership, not just the up-front price tag, should credit the DELTA 3 Ultra's longer cycle rating — it's doing real work in the math.
The DELTA 3 Ultra is a known quantity here, both on the spec sheet and in testing where reviewers found the fans never became distracting even under heavy loadA1A2. The Elite 320 simply doesn't tell you what to expect.
DELTA 3 Ultra discloses a 30dB noise rating, and reviewers report the fans stay unobtrusive even at maximum inverter outputElite 320's spec sheet includes no noise figure at all
Why it mattersBuyers shopping specifically for a bedroom or CPAP unit should weight the DELTA 3 Ultra's disclosed, reviewer-backed 30dB spec heavily against the Elite 320's undisclosed one.
Only the DELTA 3 Ultra can add capacity later without a full replacement purchase. At near-identical weight, that optionality comes at no physical cost — it's a pure upside for anyone whose power needs might change.
DELTA 3 Ultra: 77.2 lbs, expandable with add-on battery packsElite 320: 74.96 lbs, sealed at 3,200Wh
Why it mattersBuyers with growing needs — a bigger van build, more solar days, a future home-backup expansion — should credit the DELTA 3 Ultra's expansion path since it costs nothing in portability to keep open.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Every scenario is a near-tie, which is itself the finding — this page isn't decided by capacity.
Weekend Camping, the 8-Hour Blackout, CPAP Overnight, Remote Workday, and Tailgate Party all land within 3 percentage points between the two units — genuine ties, not close calls dressed up as ties. Neither unit is meaningfully more or less stressed by any of these real-world loads than the other.
Van Life Daily beats both, needing 4,685Wh against usable capacities in the low-to-mid 2,000s — a different capacity class than either unit offers. The takeaway from the scenario table is blunt: if you're deciding based on which one runs your stuff longer, you're deciding based on noise.
Lifetime Value
Selected because: Near-identical $0.10/kWh despite different sticker prices and cycle counts — worth unpacking why.
cost / lifetime kWh
Both units land at roughly $0.10 per lifetime kWh, but they get there differently. The Elite 320 combines a lower price ($999) with a lower cycle count (3,000); the DELTA 3 Ultra combines a higher price ($1,199) with a third more cycles (4,000) — the two effects roughly cancel out.
Cost per warranty year favors the Elite 320 at $200 against the DELTA 3 Ultra's $240, since warranty length is identical at 5 years for both. If cheaper ownership on paper is the only priority, the Elite 320 is technically ahead there — even though the two units end up nearly tied on total lifetime cost.
What the Specs Don't Tell You
Selected because: Surge ratio and noise disclosure are the two gates that actually separate these units in practice.
rated cycles
The surge gap is the sharpest number on this page: 7,200W for the DELTA 3 Ultra against 2,700W for the Elite 320, a ratio that matters directly for anything with a compressor or motor. That's not a marketing spec — it's the number that decides whether a fridge or AC unit actually starts.
Noise disclosure cuts the same direction. The DELTA 3 Ultra publishes 30dB and reviewers back it up under real loadA1A2; the Elite 320's spec sheet has no noise figure at all. One of these is a known quantity before you buy it.
Growth Path
Selected because: Only the DELTA 3 Ultra expands, at essentially no weight penalty.
solar input
The DELTA 3 Ultra supports EcoFlow's expansion batteries, so its 3,072Wh starting capacity can grow without a full unit replacement. The Elite 320 is sealed — 3,200Wh is the permanent number, whatever your needs do later.
Because the two units weigh within 2.24 lbs of each other, that expansion path isn't costing the DELTA 3 Ultra anything in portability. It's a free option for buyers who might need it, and irrelevant for buyers who won't.

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
Either unit
Both units cover a two-night camping load with room to spare and within a few points of each other. Pick on price or surge headroom, not runtime — runtime isn't the differentiator here.
Battery budget usedlower = more headroom
LOAD Phone Charger 15W×6h · LED Lights 40W×8h · Box Fan 75W×14h · CPAP Machine 40W×16h
SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Either unit
Both survive the blackout with similar margin. Since the capacity difference doesn't matter here, focus on which unit has UPS mode — seamless switchover protects your router and PC from the split-second power gap.
Battery budget usedlower = more headroom
LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h
SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A genuine tie on power — both units use around 12% of their tank overnight. The real decision here is noise, and only the DELTA 3 Ultra tells you what to expect before you buy.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
Either unit
Both power your workstation all day without breaking a sweat. At these utilization levels, prioritize the unit with better USB-C output for direct laptop charging. It's more convenient than using the AC inverter and wastes less energy.
Battery budget usedlower = more headroom
LOAD Laptop 60W×8h · External Monitor 30W×8h · Router + Modem 20W×8h · Phone Charger 15W×2h
SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
Either unit
Both handle game day easily. Since capacity isn't the deciding factor, consider weight: the lighter unit is easier to load into a truck bed. Also check if either has Bluetooth speaker-level noise. Fan sound matters in social settings.
Battery budget usedlower = more headroom
LOAD Blender 400W×0.5h · LED TV (55") 80W×4h · Bluetooth Speaker 15W×4h · Phone Charger (×3) 45W×2h
SCN-06 · 24 hours · needs 4,685Wh
Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit can fully handle this scenario (needs 4,685Wh). You'd need a higher-capacity station or to cut back on usage.

Conclusion
July 14, 2026
Verdict: the EcoFlow DELTA 3 Ultra
Every scenario the engine models comes back a tie or a near-tie — Weekend Camping, the 8-Hour Blackout, CPAP Overnight, Remote Workday, and Tailgate Party all land within 3 percentage points of each other. That means capacity isn't the deciding factor here; headroom is. The DELTA 3 Ultra's 3,600W continuous output already exceeds the Elite 320's 2,700W surge ceiling, its 4,000-cycle rating beats the Elite 320's 3,000 by a third, and it discloses a 30dB noise spec where the Elite 320 discloses nothing. All of that costs $200 more. If you'll never push either unit past a light household load, the Elite 320's price is the better number to chase. If you want margin for a real appliance surge, pay the $200.

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 Ultra rates 5.0/5 (99th percentile of 25 Large-class units), and Elite 320 rates 3.9/5 (38th percentile of 25 Large-class units).

Weight Reality Check
Neither unit is grab-and-go. The Elite 320 (75 lbs) is manageable solo but heavier than a large checked suitcase. The DELTA 3 Ultra (77.2 lbs) is noticeably heavier. That's a 2 lb difference.
Elite 320: Fixed Capacity
The Elite 320 is sealed at 3,200Wh — a complete unit, and already larger than the DELTA 3 Ultra's 3,072Wh. The DELTA 3 Ultra can add expansion batteries, but that only pulls ahead if you'd grow past 3,200Wh.
The DELTA 3 Ultra's Continuous Rating Beats the Elite 320's Surge Ceiling
3,600W continuous against a 2,700W surge ceiling isn't a marginal gap — it means the DELTA 3 Ultra can sustain what the Elite 320 can only briefly absorb. That matters directly for anything with a compressor or motor.
4,000 Cycles vs 3,000, Same 5-Year Warranty
The DELTA 3 Ultra is rated for a third more charge cycles under an identical warranty term, which is most of why it edges out the Elite 320 on cost per lifetime kWh despite the higher sticker price.
One Unit Publishes Its Noise Level, One Doesn't
The DELTA 3 Ultra lists 30dB and reviewer testing backs it up under real load. The Elite 320's spec sheet has no noise figure at all — worth checking before a bedroom or CPAP purchase.

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/chat support (1-800-368-8604). Experiences are polarized — many report hassle-free prepaid-label replacements, but others report long waits and refurbished units sent for new claims. Pro tip: buying from Costco or Amazon gives you a stronger return safety net.
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
EcoFlow runs the deepest product ecosystem in the category and the fastest-charging technology in its lineup, with the most active innovation cadence of any major brand.
Worth knowing
A October 2025 recall on an unrelated model (DELTA Max 2000, overheating risk) is worth knowing about the brand generally, and EcoFlow briefly tested subscription paywalls for app features before backing off under community pressure.
BLUETTI
Ecosystem
One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship (Apex 300, 3072Wh). 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 holds the strongest capacity-to-price ratio in the market, with full LiFePO4 standardization across its lineup and dual-voltage support in flagship units.
Worth knowing
Support quality is the most inconsistent in the category — heavily email-based with delays, though buying direct from BLUETTI tends to produce smoother outcomes than third-party retailers.
Analyst note
EcoFlow's premium buys a deeper ecosystem, faster charging tech, and a stronger app track record; BLUETTI's value pricing buys more capacity per dollar with a less consistent support experience. Neither brand gap is large enough to override the spec differences between these two specific units.
Growth path
DELTA 3 Ultra
EXPANDABLESupports EcoFlow expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 3,072Wh.
Accepts up to 1,600W of solar. Enough for a serious multi-panel array.
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. No expansion port, but that capacity already covers heavy and multi-day loads.
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 Ultra's expandability as a straight win here: it starts at 3,072Wh, 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 Ultra
Most available commentary on this exact model actually covers the higher DELTA 3 Ultra Plus tier rather than the base Ultra sold here, since the two share overlapping specs and reviewers themselves note the naming overlap — treat the following as directionally representative of the family rather than confirmed on this specific SKU. With that caveat, reviewers consistently describe the fans as staying unobtrusive even when the inverter is pushed to its maximum output, a clear step up from older EcoFlow unitsA1A2.
UPS switchover performance draws repeated praise — testers report no dips or shutdowns when pulling the unit off wall power, comparable to dedicated APC battery backupsA5A6. Build quality is called out as solid and durable rather than cheap-feelingA9, and the unit's roughly 74-77 lb weight is flagged consistently as the one real ownership tradeoff, mitigated by wheels and a telescoping handleA10A14.
“Even when you're pushing it hard, the DELTA 3 Ultra Plus runs much quieter than older EcoFlow models, like the DELTA 2 Max.”

BLUETTI Elite 320
What reviewers keep returning to is refrigeration math: over 66 hours of fridge runtime and up to two days of essential household power off one charge, delivered through four AC outlets and dual USB-C ports rated at 140W and 100WB3.
Coverage frames it plainly as a suitcase-style home-backup unit — a 3,200Wh LiFePO4 pack rated for 1,800W continuous, 2,700W in Power Lifting mode, with a 10ms UPS switchoverB1 — and at roughly 75 lbs it rides on oversized shock-absorbing wheels with a retractable handle rather than asking anyone to lift itB2.
“A 3,200Wh LiFePO4 battery delivering 1,800W continuous (2,700W Power Lifting, 3,600W peak), with 10ms UPS protection — a suitcase-style rolling home-backup station introduced at CES 2026.”

Who Should Buy Which
Buy the DELTA 3 Ultra if you…
- →You want real headroom for a compressor-heavy load — a fridge, window AC, or power tool — where the Elite 320's 2,700W surge ceiling is a tighter fit than the DELTA 3 Ultra's 7,200W.
- →You want a documented, reviewer-backed noise spec for a bedroom or CPAP setup instead of an unpublished number.
- →You want the option to add capacity later without paying $200 more in weight to keep that door open.
Buy the Elite 320 if you…
- →You're running light household loads — CPAP, laptop, router, occasional appliance — where every modeled scenario ties anyway, and $200 buys headroom you won't use.
- →You want the lower cost per warranty year and don't need the extra cycle life or surge ceiling.
- →You're not planning to expand past 3,200Wh and would rather save the $200 up front.
If neither fits
If your real need is full-time daily power, the Van Life Daily scenario needs 4,685Wh — well beyond what either unit's usable capacity covers even before accounting for daily draw. Look at a larger-capacity system or a genuinely modular multi-battery setup instead of choosing between these two.
The Bottom Line
Strip away the marketing and this comparison is a near-total tie on runtime — five of six scenarios land within 3 percentage points. What separates the two units is headroom: the DELTA 3 Ultra's 3,600W continuous output alone beats the Elite 320's entire 2,700W surge ceiling, and it backs that with a third more cycle life and a disclosed noise spec.
That's worth $200 to anyone starting real appliances or planning to grow into more capacity. If your loads are light and your needs are fixed, the Elite 320 is the same job for less money.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the EcoFlow DELTA 3 Ultra worth $200 more than the BLUETTI Elite 320?
Only if you need the headroom it buys. Every real-world scenario this site models ties or nearly ties between the two units, so the $200 isn't buying more runtime — it's buying a 7,200W surge ceiling instead of 2,700W, 1,000 more rated cycles, and a disclosed 30dB noise spec. If your loads are light, save the money.
Which one can actually start a fridge or AC unit more reliably?
The DELTA 3 Ultra, by a wide margin. Its 3,600W continuous rating already exceeds the Elite 320's entire 2,700W surge ceiling, which matters because compressor startup can briefly draw 2-3x the running wattage.
Which one is quieter?
The DELTA 3 Ultra discloses 30dB and reviewers confirm the fans stay unobtrusive even under maximum load. The Elite 320 doesn't publish a noise figure at all, so there's no comparable number — a gap worth knowing about before a bedroom purchase.
Does either of these expand with add-on batteries?
Only the DELTA 3 Ultra. It supports EcoFlow's expansion battery packs, so capacity can grow past 3,072Wh later. The Elite 320 is sealed at 3,200Wh for the life of ownership.
Which one should I actually buy?
If every scenario ties and your loads are light, take the Elite 320 and keep the $200. If you need surge headroom for real appliances, more cycle life, or a documented noise spec, the DELTA 3 Ultra's premium is buying something real.
