Head-to-head test
EcoFlow DELTA 3 Plus vs BLUETTI Elite 100 V2
On paper these two are twins, down to the same 3,600W surge figure. The DELTA 3 Plus costs $220 more and buys one real thing with it: a port for an expansion battery. If you'll never plug one in, the Elite 100 V2 is the same station for less.

Spec deltas
I laid these two spec sheets side by side expecting to find the catch. Capacity, continuous output, cycle rating, solar input: the same numbers on both. Even the surge figure matches at 3,600W each. Surge is the brief spike a motor pulls as it starts.
BLUETTI does list a second, smaller figure for the Elite, Power Lifting to 2,700W. That's a mode for heaters and kettles, which it runs at reduced voltage so they work slower instead of tripping the inverter. It does nothing for a motor, and the DELTA has no equivalent. It's easy to mistake for a surge rating. The Elite's surge rating is the separate 3,600W figure.
So the differences are short. The Elite is $220 cheaper and 2 lbs lighter. The DELTA takes an expansion battery and has six AC outlets to the Elite's four. Reviewers have also reported its fans cycling on and off erratically, even at light loadsA1.
What the Numbers Reveal
Each conclusion stated first β the numbers behind it on one line, the full analysis below.
cost / lifetime kWh
So the cost to own comes down to the sticker. The Elite's lower price puts it at $0.12 per lifetime kilowatt-hour against the DELTA's $0.18.
the Elite 100 V2 is $499 vs the DELTA 3 Plus's $719both hold 1,024Wh rated for 4,000 cycles, about 4,096 kWh over their rated livesthe Elite works out to $0.12 per lifetime kWh; the DELTA to $0.18
Why it mattersOn the core hardware, the Elite gives you the same battery for $220 less.
The Elite's 2,700W figure belongs to Power Lifting, a mode that runs a heater or kettle rated above the inverter at reduced voltage. It doesn't touch motor loads. For a fridge compressor or a pump the number to read is surge, and there they're level.
both run 1,800W continuous and publish a 3,600W surge peakthe Elite also lists Power Lifting to 2,700W for resistive loads; the DELTA publishes no equivalent
Why it mattersIf a motor is in your plans, neither has the edge on paper. If a kettle or a heater is, the Elite has a mode the DELTA lacks.
Only the DELTA can close that gap without being replaced. Add an EcoFlow expansion battery and it runs the same loads for longer. The Elite's ceiling is the box you bought.
the DELTA 3 Plus takes EcoFlow expansion batteries; the Elite is sealed at 1,024Whan 8-hour blackout needs about 1,645Wh, 189% of either unit's usable capacitythe DELTA costs $220 more
Why it mattersIf outages are on your mind and you'd add a battery later, the DELTA's extra $220 buys that path. If 1,024Wh covers you, you're paying for a port you won't use.
Reviewers can. Two flagged the DELTA's fans switching on and off erratically at light loadsA1, and one warned it could raise overheating risk under heavy loadsA2. They expect EcoFlow can fix it in a software updateA4. The Elite drew the opposite note, with some reviewers never hearing its fans, though that's in Silent mode, which caps powerB1.
both are rated 30dB by their makersreviewers report the DELTA 3 Plus's fans cycling on and off erratically even at low loadA1reviewers found the Elite 100 V2 quiet in practice, in its power-capping Silent modeB1
Why it mattersFor a bedside unit I'd lean to the Elite until EcoFlow ships that fixA4.
The specific dimensions that decide these two units β everything else is a tie.
Lifetime Value
Selected because: The Elite is the same core unit for $220 less and cheaper to own, its central case.
cost / lifetime kWh
Both hold 1,024Wh and are rated for 4,000 cycles, so both are rated to deliver the same lifetime energy. That leaves price to decide the cost to own. The Elite's comes to $0.12 per lifetime kilowatt-hour, the DELTA's to $0.18.
When two stations match this closely, the cheaper one wins the money argument without trying. The DELTA's extra money goes to an expansion port and two more outlets. Whether that's good value depends on whether you'll use them.
What the Specs Don't Tell You
Selected because: Power Lifting reads like a weaker surge figure; the two actually publish the same surge peak.
Power Lifting is the spec most likely to mislead here. The Elite lists it at 2,700W. It means the Elite can run a heater or kettle rated above its 1,800W inverter, more slowly, by feeding it reduced voltage. BLUETTI scopes it to resistive loads, so a fridge, a pump or a saw gets nothing from it.
For motors, read surge. Both publish 3,600W, so neither has the paper edge on starting a compressor. The warranty is level too, 5 years on each, with the Elite's term depending on buying direct from BLUETTI or registering it.
Growth Path
Selected because: Expandability is the DELTA's real premium; the Elite is sealed but matches on solar.
The DELTA's other real advantage is expansion. It accepts EcoFlow batteries, so it can grow past its 1,024Wh base. At this size, expansion buys longer runtimes on the same loads.
The Elite is sealed at 1,024Wh. If that covers you, a sealed box is one less thing to think about. Both take the same 1,000W of solar, so they're level on recharge speed.
Brand Trust
Selected because: Cross-brand: EcoFlow's ecosystem and expansion vs BLUETTI's value.
EcoFlow has the deepest lineup in portable power and an app owners rate well. Its support is US-based, and replacement stories run from easy prepaid-label swaps to long waits. BLUETTI leads on capacity per dollar and its app rates about as well. Its support is the most inconsistent in the space, and buying direct tends to go better.
For a 1kWh station you'll mostly set and forget, the brand gap matters less than the price and the behaviour in front of you. EcoFlow's edge here is the expansion path. BLUETTI's is the lower price.

Neither unit
A camping weekend with a fridge needs about 2,100Wh. Each base unit covers about 41% of it. The DELTA can add an expansion battery to close the gap. The Elite needs help from a panel, and both take 1,000W of solar to refill quickly between days.

CPAP Overnight
Sleep therapy without interruption β the #1 medical use case
Either unit
A CPAP draws about 40W, so a night comes to around 320Wh. Either covers it more than twice over. Both list 30dB, each maker's own figure, so the spec sheet can't pick a quieter one. The Elite is cheaper and lighter, which settles the tie.

SCN-04 Β· 8 hours Β· needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
Neither unit
A day of laptop, monitor and router needs about 910Wh. Both come up about 40Wh short of it on usable energy. Drop one small device, or top up from solar at lunch, and either finishes.

Conclusion
October 25, 2026
Verdict: the Elite 100 V2
For most buyers, the BLUETTI Elite 100 V2. The two match on capacity, continuous output, published surge, rated cycles, solar input and UPS switchover rating. The Elite costs $220 less, which makes it cheaper to own at $0.12 per lifetime kilowatt-hour against $0.18, and it's 2 lbs lighter. The DELTA 3 Plus earns its premium in two ways: it takes EcoFlow expansion batteries, and it has six AC outlets to the Elite's four. Reviewers have also flagged its fans cycling on and off at light loadsA1. If you expect to grow past 1kWh, buy the DELTA. Otherwise buy the Elite.

Hidden gotchas and advantages we spotted that you won't find on the product page.
One Grows, One Is Sealed
The DELTA 3 Plus accepts EcoFlow expansion batteries to climb past its 1,024Wh base. The Elite 100 V2 is sealed at 1,024Wh. A single blackout or workday already overruns that, so for a 1kWh station the option to add more is a real path. It's the clearest reason to pay the DELTA's $220 premium, if you'll use it.
Power Lifting: For Heaters and Kettles
The Elite 100 V2 can run a resistive appliance rated up to 2,700W from its 1,800W inverter. It does that by feeding the appliance less power than it asks for, so a heater still works and heats more slowly. BLUETTI limits the mode to heaters, kettles and incandescent lamps. Fridge compressors, pumps and power tools get nothing from it. For those, read surge: both units publish 3,600W. The DELTA 3 Plus has no Power Lifting equivalent.
Same 5 Years
Both carry a 5-year warranty. The Elite 100 V2's term is a maximum that depends on buying direct from BLUETTI or registering it, since reseller purchases carry a shorter term. Spread over each price, the Elite gives more years of cover per dollar. That spread comes from the price gap. The terms are the same.

Analyst note
The Elite 100 V2 wins on both sticker price and long-term value. At $0.12/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner. 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 β the wear horizon is identical and decides nothing here.

Unique strength
Among the best capacity per dollar in the market, and an app rated with the best in the category. LFP cells across the range, with rated cycle life that varies by model.
Worth knowing
Support inconsistency is the main risk, and some older or discontinued units can become unrepairable with no spare-parts policy.
Analyst note
EcoFlow sells ecosystem depth and an expansion runway at a mid-to-premium price. BLUETTI sells value and range, with the category's most inconsistent support. For this pair, that's EcoFlow's pricier, expandable DELTA 3 Plus against BLUETTI's cheaper, sealed Elite 100 V2. Both brands are safe choices. The question is whether you'll expand.

Analyst note
The Elite 100 V2 is sealed at 1,024Wh, which is fine if that covers you. The DELTA 3 Plus starts at 1,024Wh and can grow beyond it with EcoFlow expansion batteries β though at this size expansion means longer runtimes on the same loads, not a path to home backup. More hours, not more house.

BLUETTI Elite 100 V2
The Elite 100 V2 is a 2026 release with strong early reviews. Testers rate it among the quicker solar chargers in the 1kWh class, with a full charge in about an hour from 1,000W of panelsB2. One, after 30 days with it, called it the best portability-to-power ratio in the classB5. Some never heard its fans while it ran a large heater, in Silent mode, which caps power. Turbo is louderB1.
Reviewers also like the cells and the build, with nothing rattling inside when it's movedB3. The thing to watch is a minority of owner reports of charging failures or a display reading zero chargeB4. Our researcher couldn't confirm every report concerns this exact modelB4. On a new unit I'd still buy where returns are easy.
βReviewers found it remarkably quiet in practice β 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.β

Who Should Buy Which
Buy the DELTA 3 Plus if youβ¦
- βYou expect to outgrow 1kWh. It takes EcoFlow expansion batteries and the Elite can't.
- βYou need more sockets. It has six AC outlets to the Elite's four.
- βYou're already in EcoFlow's ecosystem and can live with the fan behaviour until a firmware fix landsA4.
Buy the Elite 100 V2 if youβ¦
- βYou want the same core station for $220 less, and 2 lbs lighter to carry.
- βYou're sure 1,024Wh covers you and you won't add a battery later.
- βYou'd run a heater or kettle rated above 1,800W. The Elite's Power Lifting mode runs those, more slowly, and the DELTA has no equivalent.
If neither fits
If you need a full 8-hour blackout or a workday from the base unit, neither does it alone. The DELTA can get there with an expansion battery. The sealed Elite would mean buying a bigger station. And if you only charge phones and a laptop, a smaller station would save you money.
The Bottom Line
Buy the BLUETTI Elite 100 V2 unless you know you'll add a battery. It matches the DELTA 3 Plus on capacity, output, surge, cycles, solar and UPS rating, for $220 less and 2 lbs lighter.
The DELTA 3 Plus earns its premium if you'll use what it adds: an expansion port and two more AC outlets. If you can see yourself buying an EcoFlow battery in a year or two, that's worth paying for now.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
EcoFlow DELTA 3 Plus or BLUETTI Elite 100 V2: which should I buy?
For most buyers, the BLUETTI Elite 100 V2. It matches the DELTA 3 Plus on capacity, output, surge, cycles, solar and UPS but costs $220 less ($499 vs $719), is 2 lbs lighter and is cheaper to own. Reviewers have also reported the DELTA 3 Plus's fans cycling erratically even at low load. The DELTA's premium buys expandability and two extra AC outlets. Buy the DELTA if you need to grow past 1kWh; otherwise the Elite is the better value.
Which one has the higher surge rating?
Neither. Both publish a 3,600W surge peak on an 1,800W inverter. The Elite 100 V2's 2,700W figure is Power Lifting, a separate mode for resistive loads such as heaters and kettles, which it runs at reduced power. It is not a surge rating and does nothing for motor loads.
Which is quieter?
Both are rated 30dB, so the spec sheets can't separate them. In reviews, the DELTA 3 Plus's fans cycle on and off erratically even at low load, undercutting its quiet-UPS billing, while reviewers found the Elite quiet, sometimes never hearing its fans, in its power-capping Silent mode. EcoFlow may fix the DELTA in firmware.
Can I expand either one?
Only the DELTA 3 Plus. It accepts EcoFlow expansion batteries to grow past its 1,024Wh base; the Elite 100 V2 is sealed at 1,024Wh. Since a single blackout overruns a 1kWh station, that expandability is the DELTA 3 Plus's most practical justification for its $220 premium, if you'll actually use it.
Do they charge from solar at the same speed?
Yes. Both take 1,000W of solar, which fills a 1,024Wh battery in about an hour, and reviewers report the Elite doing just that. The two are even on solar, UPS rating, capacity and cycle life, which is why price and expandability decide this pair.
