Head-to-head test
EcoFlow DELTA 3 vs BLUETTI Elite 100 V2
Two quiet, 10ms-UPS 1kWh units, and the split just sharpened: the BLUETTI Elite 100 V2 is now the cheaper one, and it already took double the solar, lasted more cycles, and weighed less — while the EcoFlow DELTA 3 answers with expandability past 1kWh and a harder surge. For most buyers, especially solar-first ones, the cheaper, longer-lived Elite now leads; the DELTA stays the pick for expansion or maximum surge.

Spec deltas
Two well-matched 1kWh units from the two biggest value brands — but the pricing has crossed over. The BLUETTI Elite 100 V2 is now $499; the EcoFlow DELTA 3 is $629. They share the fundamentals — 1,024Wh, 1,800W, a 10ms UPS, a 30dB rating, a 5-year warranty — so the decision lives in how they differ, and they differ in interesting ways.
The Elite 100 V2 is now the cheaper one, and it was already the solar-and-longevity one. It takes double the solar input (1,000W vs 500W), enough for a full charge in about an hourB2, is rated for 4,000 cycles to the DELTA 3's 3,000, and weighs 2 lbs less — so it's cheaper up front and cheaper to own.
The DELTA 3's answers are about flexibility, not price. It expands past 1,024Wh with add-on batteries where the Elite is sealed, and it surges to 3,600W against the Elite's 2,700 — more headroom for a fridge or pump. Same class, genuinely different strengths — and the value edge has swung to the Elite.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Typical price
The DELTA 3 now costs $130 more, but it expands past its 1,024Wh base where the Elite 100 V2 is a sealed box, and surges to 3,600W (2.0x) to the Elite's 2,700W (1.5x) — more flexible and better at starting motor loads, if no longer the cheaper way to get there.

Why it mattersFor a small unit that runs out fast, the DELTA's ability to grow — and its surge — are why you'd pay its premium.
solar input
The Elite 100 V2 takes 1,000W of solar to the DELTA 3's 500W — double the input, enough for a full charge in about an hourB2 — which is a genuine advantage for anyone who recharges off-grid rather than from the wall.

Why it mattersSolar-first buyers should weigh the Elite heavily; its recharge speed is the best in this matchup, and it now costs less too.
weight
The Elite 100 V2 is rated for 4,000 cycles to the DELTA 3's 3,000, which makes it much cheaper to own ($0.12 vs $0.18 per lifetime kWh) now that it's also the cheaper unit up front, and at 25 lbs it's 2 lbs lighter — the longer-lived, more portable, and cheaper option.

Why it mattersIf you'll cycle it hard for years or carry it often, the Elite's longevity, weight, and price all tilt its way.
Both share a 10ms UPS and a 30dB rating, and both are quiet in practice — though the Elite's sub-30dB only holds in a Silent mode that caps powerB1, while the DELTA 3's fans simply stay off under light loadA1.

Why it mattersFor a bedside unit both are excellent; just know the Elite trades power for its quietest mode.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The Elite now wins both the sticker and the lifetime math — the value case flips to it.
cost / lifetime kWh
The value picture no longer splits — it lines up behind the Elite. Up front, the Elite 100 V2 is now cheaper ($499 to $629). Over the long run it pulls further ahead: its 4,000-cycle rating tops the DELTA 3's 3,000, delivering 4,096 kWh over its life to 3,072, which drops cost-to-own to $0.12 per lifetime kWh against $0.18.
So the Elite now wins the sticker and the lifetime math — where it used to trade the sticker for the long-run edge, it takes both. The DELTA 3 isn't overpriced for what it does, but it no longer has a value argument; its case is expandability and surge.
Growth Path
Selected because: Expansion (DELTA) vs double-solar recharge (Elite) is the core philosophical divide.
solar input
This is where the two philosophies diverge. The DELTA 3 is expandable — add EcoFlow batteries and it grows past 1,024Wh — which matters because a 1kWh unit runs out fast; a single blackout overruns it. The Elite 100 V2 is a sealed box: what you buy is the ceiling.
The Elite's answer is to refill faster instead of growing. Its 1,000W solar input is double the DELTA 3's 500W, enough for a full charge in about an hour of strong sunB2. So the growth question is really a question about you: if you might need more capacity, the DELTA's expansion wins; if you'll keep it at 1kWh and recharge from solar, the Elite's input speed does.
Brand Trust
Selected because: Cross-brand: EcoFlow's ecosystem/expansion vs BLUETTI's value and app.
Both are value-brand leaders with different reputations. EcoFlow runs the deepest ecosystem and best app in portable power, with polarized US support. BLUETTI offers the best capacity-per-dollar and the broadest lineup, and — tied for the best app in the category — a genuinely good software experience, though its support is the most inconsistent in the space.
For a small, set-and-forget 1kWh unit, the brand gap matters less than it would on a big investment. Both apps are well-rated; both companies have their support caveats. If you value ecosystem depth and expansion, EcoFlow leans your way; if you value the app and raw capacity-per-dollar, BLUETTI does.
What the Specs Don't Tell You
Selected because: Surge, cycle life, and the Elite's noise-mode caveat are the real spec-sheet texture.
Two spec-sheet differences worth flagging. Surge: the DELTA 3 hits 3,600W (a 2.0x ratio) to the Elite's 2,700W (1.5x), so it's the better bet for starting a fridge or pump. Cycle life: the Elite 100 V2 is rated for 4,000 cycles to the DELTA 3's 3,000 — about a third more full charge-and-drain trips, which pairs with its lower price to make it clearly cheaper to own.
The other thing the sheet hides is the Elite's noise caveat: its 30dB rating applies in a Silent mode that caps charge and discharge powerB1, with Turbo mode louder. The DELTA 3, also rated 30dB, keeps its fans off under light load without a mode switchA1. Both are quiet for a bedside CPAP; the DELTA is simply quieter at full tilt.

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
Neither unit
Two nights wants 2,100Wh and these hold 1,024, so both overrun at 241%. Neither is a weekend battery alone — the DELTA 3 gets there by adding an expansion pack, while the sealed Elite 100 V2 would need a bigger unit. If you'll recharge from solar between days, the Elite's 1,000W input refills far faster.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
A full blackout needs 1,645Wh, past the 1,024 either holds, so both land at 189%. For real coverage, the DELTA 3 can add an expansion battery; the sealed Elite can't. If a fridge is on the line, the DELTA 3's higher surge is also the safer bet for starting it.

SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A 40W CPAP uses about 37% of either overnight, so capacity is fine, and both are quiet at this load. Decide on the things that differ — expandability and surge (DELTA 3) or price, solar, and longevity (Elite) — not runtime.
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
Neither unit
A full day at the desk edges just past either unit's 1,024Wh at 105%, so neither quite lasts on the base alone. A small expansion pack (DELTA 3) or a midday solar top-up (the Elite's 1,000W input shines here) covers it either way.

SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
Either unit
Game day fits on either at about 77% of the battery — the one everyday scenario the base units clear. Both are light for 1kWh; the Elite is 2 lbs lighter and now $130 cheaper, while the DELTA 3 can expand and surges harder. Pick your priority.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Not close — a van-life day wants 4,685Wh and these hold 1,024, so both bury the needle at 538%. The DELTA 3 expands toward it; the sealed Elite doesn't, though its double solar input helps stretch a day off-grid. For real van life, size up regardless.

Conclusion
July 12, 2026
Verdict: the Elite 100 V2
A close cross-brand call that the price move settles for most buyers: the BLUETTI Elite 100 V2. It's now $130 cheaper than the EcoFlow DELTA 3 ($499 vs $629), and it already led on the axes a price change can't touch — double the solar input (1,000W vs 500W) for a full solar charge in about an hourB2, a 4,000-cycle rating to the DELTA's 3,000, and 2 lbs less weight. Together with the lower price, that opens a real cost-to-own gap ($0.12 vs $0.18 per lifetime kWh). The DELTA 3 keeps two genuine edges — it expands past its 1,024Wh base where the Elite is sealed, and it surges to 3,600W (2.0x) against the Elite's 2,700W (1.5x) — so it stays the pick for buyers who need expandability or maximum surge. For everyone else, especially solar-first buyers, the cheaper, longer-lived Elite is now the default.

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 4.4/5 (65th percentile of 27 Everyday-class units), and Elite 100 V2 rates 4.8/5 (88th percentile of 27 Everyday-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
One Grows, One Is Sealed
The DELTA 3 accepts EcoFlow expansion batteries to climb past its 1,024Wh base; the Elite 100 V2 is a sealed unit at 1,024Wh. For a 1kWh station this matters more than it would higher up the range — a single blackout or workday already overruns 1,024Wh, so the ability to bolt on more is a real path forward. The Elite counters with faster solar recharge instead of expansion; which you'd rather have is the core of this decision.
The DELTA 3 Starts Tougher Appliances
Both run 1,800W continuous, but the DELTA 3 surges to 3,600W (a 2.0x ratio) against the Elite 100 V2's 2,700W (1.5x). Motors in fridges, pumps, and power tools briefly pull 2-3x their rated watts at startup, so the DELTA 3's extra headroom makes it more likely to start a stubborn compressor without tripping. For electronics and resistive loads, both are plenty; this matters only if a motor is in the mix.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The Elite 100 V2's figure is a maximum rather than a guarantee — it depends on buying direct from BLUETTI or registering the unit, since reseller purchases carry a shorter term. Worth saying because the per-dollar framing can suggest otherwise: the Elite 100 V2 works out at 10 years of cover per $1,000 spent against the DELTA 3's 7.9, but that spread is the price gap, not the terms.

Analyst note
Both units have similar long-term ownership costs ($0.15/kWh vs $0.12/kWh). The price difference is what you see on the sticker — neither is a hidden bargain or rip-off. 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 in portable power — a dozen-plus models across the DELTA and RIVER lines plus solar and smart-home panels, scaling to 180kWh modular systems at the top.
Support
US-based phone, email, and chat. Replacement experiences are polarized: many hassle-free prepaid-label swaps, but also reports of long waits and refurbished units for new claims. Costco or Amazon adds a 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
The best app and fastest charging in the category, plus the widest ecosystem and a real expansion runway — up to 180kWh at the top of the line.
Worth knowing
Note the October 2025 DELTA Max 2000 recall (overheating risk, six incidents), and a brief 2025 experiment with app-feature paywalls that backlash paused. No out-of-warranty parts or service.
BLUETTI
Ecosystem
One of the broadest lineups anywhere, from budget units to 3kWh-plus flagships, including industry-firsts like sodium-ion cold-weather stations and dual solar-plus-alternator vehicle hubs.
Support
The most inconsistent support in the space — heavily email-based with China-timezone delays. Some owners get smooth service; others describe weeks of runarounds. Buying direct from BLUETTI tends to go better than third-party.
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
The best capacity-per-dollar in the market, an app tied for best in the category, and full LFP standardization (3,500-6,000+ cycles across the line).
Worth knowing
Support inconsistency is the number-one risk, and some older or discontinued units can become unrepairable with no spare-parts policy.
Analyst note
EcoFlow sells ecosystem depth — the widest lineup, the best app, and a real expansion runway — at a mid-to-premium position. BLUETTI sells value and diversity: the best capacity-per-dollar, a top-rated app, and unusual products, though with the category's most inconsistent support. For this pair, that plays out as EcoFlow's expandable DELTA 3 versus BLUETTI's cheaper, solar-fast, longer-lived Elite 100 V2. Both brands are safe; pick the one whose strength matches your use.
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 100 V2
FIXED CAPACITYFixed at 1,024Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
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
The Elite 100 V2 is sealed at 1,024Wh, which is fine if that covers you. The DELTA 3 starts at 1,024Wh and can grow beyond it with EcoFlow expansion batteries — though at this size expansion means longer runtimes on the same loads, not a path to home backup. More hours, not more house.
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 thin — most testing goes to its Plus, Max, and Ultra siblings — but the findings that exist are strong. Reviewers report its fans staying off under about 200W, making it effectively silent, and barely audible at moderate loadA1, with a ~10ms UPS handoff quick enough that routers, fridges, and CPAPs don't skip through a power cutA2.
That quiet-plus-fast-UPS combination is exactly what a small backup unit should deliverA1A2. Long-term reliability is still unproven given how new the unit is, so treat the sentiment as preliminary.
“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 100 V2
The Elite 100 V2 is a well-reviewed 2026 release. Reviewers rate it among the faster solar chargers in the 1kWh class — 1,000W input with built-in MPPT for a full charge in about an hourB2 — and call out durable LiFePO4 cells rated up to 4,000 cycles with solid, rattle-free buildB3. After 30 days one tester named it the best portability-to-power ratio in the classB5.
It's quiet in practice too, with reviewers sometimes never hearing the fans — though the sub-30dB claim holds only in Silent mode, which caps power, while Turbo is louderB1. The one negative to watch: a minority of owner reports mention charging failures or the display showing zero chargeB4, worth keeping an eye on given how new the unit is.
“Reviewers found it remarkably quiet in practice — some never heard the cooling fans even while it powered a large heater. The sub-30 dB claim only applies in Silent mode, which caps charge/discharge power; Turbo mode is noticeably louder.”

- →You'll start motor loads — its 3,600W surge (2.0x) beats the Elite's 2,700W (1.5x).
- →You want EcoFlow's deeper ecosystem and expansion pathA2.
Buy the Elite 100 V2 if you…
- →You'll recharge mostly from solar — its 1,000W input is double the DELTA 3's, for a full charge in about an hourB2.
- →You want the cheaper, longest-lived, lightest unit — $130 less, 4,000 cycles, 25 lbs — and you won't need to expand past 1kWh.
- →You want the lower cost-to-own ($0.12 vs $0.18 per lifetime kWh).
If neither fits
If you need to cover a full 8-hour blackout or a workday from the base unit, 1,024Wh isn't enough on either — the DELTA 3 gets there by expanding; the sealed Elite would need a bigger unit. And if you only run small loads, a smaller station would save money and weight.
The Bottom Line
The price move tips a genuine coin-flip toward the BLUETTI Elite 100 V2 for most buyers. It's now the cheaper unit ($499), takes double the solar for a ~1-hour chargeB2, lasts the longest (4,000 cycles), weighs the least (25 lbs), and costs the least to own ($0.12 vs $0.18 per lifetime kWh) — the value-and-solar pick.
Lean EcoFlow DELTA 3 if you specifically need to expand past 1kWh or want the higher surge for appliances — real advantages you now pay a $130 premium for. Both are excellent 1kWh stations; the Elite now wins on price, solar, and longevity, the DELTA on expansion and surge. Pick the strength that matches how you'll actually use it.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
EcoFlow DELTA 3 or BLUETTI Elite 100 V2 — which should I buy?
It's close, but the price move tips it to the BLUETTI Elite 100 V2 for most buyers. It's now $130 cheaper ($499 vs $629), takes double the solar (1,000W vs 500W) for a ~1-hour solar charge, lasts more cycles (4,000 vs 3,000, so it's cheaper to own at $0.12 vs $0.18 per lifetime kWh), and weighs 2 lbs less. The DELTA 3 expands past 1,024Wh where the Elite is sealed and surges harder (3,600W vs 2,700W) — pick it if you need expandability or maximum surge.
Which charges faster from solar?
The Elite 100 V2, clearly. It accepts 1,000W of solar to the DELTA 3's 500W — double the input — with built-in MPPT for a full charge in about an hour of strong sun. If solar is your main recharge method, that's the Elite's single biggest advantage and a strong reason to pick it over the DELTA 3.
Can I expand either one later?
Only the DELTA 3. It accepts EcoFlow expansion batteries to grow past its 1,024Wh base; the Elite 100 V2 is a sealed unit — what you buy is the ceiling. Since a 1kWh station runs out fast (a single blackout overruns it), that expandability is the DELTA 3's most practical edge for backup-minded buyers.
Which lasts longer and which is quieter?
The Elite 100 V2 is rated for more cycles — 4,000 to the DELTA 3's 3,000 — so it lasts longer and costs less to own. On noise, both are rated 30dB and both are quiet at light loads, but the Elite's sub-30dB only holds in a power-capping Silent mode, while the DELTA 3 stays quiet under light load without switching modes. For bedside use both are fine; at full power the DELTA is quieter.
