Brand matchup
EcoFlow vs BLUETTI
The measured comparison: 202 model-vs-model head-to-heads, 21 EcoFlow and 27 BLUETTI models in the current catalog, and 53 days of twice-daily price captures.
What each brand is known for
EcoFlow turned recharge time into the headline spec: most of its line refills from a wall socket in about an hour, and the catalog stretches from a 230 Wh RIVER to a 12.3 kWh DELTA Pro Ultra, 21 current models with a UPS mode on 100% of them. It reprices in small, frequent steps rather than big sales, so the median unit spent 1% of our capture window under its typical price.
BLUETTI built its reputation on the big box in the garage: LFP cells before they were standard, batteries that stack (its systems reach 39.7 kWh), and a catalog that now runs 27 current models, from a 128 Wh pocket unit to 5.1 kWh in a single chassis. The newer Elite 200 V2 and Elite 300 carry 6,000-cycle ratings, and the brand sells on events rather than drift: prices hold, then a sale cuts deep.

Every point is derived from the numbers on this page as of Sep 8, 2026 and scoped to the sizes where it holds; a lead needs at least two models on each side and a gap of 5% or more. When the catalog, the prices or the reviews move, the points move with them. A trade-off is where the data runs against the brand, not a defect report; the linked section carries the context.

03 · Decision map
Who wins where, criterion by criterion
A brand is not one product, so the question is not which brand wins but where. Each cell is the median of every current model that brand sells in that capacity band, on the typical price, the price each unit sat at most often in the last 90 days, rather than the weekend promotion. A leader needs at least two models on each side and a gap of 5% or more; anything closer is called even.

04 · Verdict by use case
Which brand for what
Bench leaders among the two brands' current units, on the same PowerScore benches that rank our buying guides. Each card links to the head-to-head that comes closest to the two leaders.
Home backup
Bench leader: EcoFlow
EcoFlow's DELTA Pro Ultra X tops the home backup bench of the two catalogs, with BLUETTI's EP500Pro at #4 of 31. The bench rewards capacity, inverter headroom and an expansion path, which is why whole-home platforms lead it; a unit parked by the fridge is a different budget question.

Camping and overlanding
Bench leader: EcoFlow
EcoFlow's DELTA 3 1500 tops the camping and overlanding bench of the two catalogs, with BLUETTI's Elite 100 V2 at #2 of 24. Camping scoring caps weight and rewards usable watt-hours per pound, so a mid-size unit can beat a bigger one.

RV and van life
Bench leader: EcoFlow
EcoFlow's DELTA Pro 3 tops the rv and van life bench of the two catalogs, with BLUETTI's Apex 300 at #2 of 27. RV scoring rewards inverter headroom, 30A-class output and an expansion path.

CPAP
Bench leader: BLUETTI
BLUETTI's Elite 200 V2 tops the cpap bench of the two catalogs, with EcoFlow's DELTA 3 Max at #2 of 30. CPAP scoring is usable watt-hours per dollar with a quiet-running bonus; for travel-sized CPAP power our CPAP guide ranks lighter units than either leader here.
Starlink and off-grid work
Bench leader: EcoFlow
EcoFlow's DELTA Pro Ultra X tops the starlink and off-grid work bench of the two catalogs, with BLUETTI's EP500Pro at #3 of 41. Off-grid work runs a dish for days, so capacity and solar input decide it and stationary systems lead; the Starlink guide ranks portable options.

Solar generator
Bench leader: EcoFlow
EcoFlow's DELTA Pro 3 tops the solar generator bench of the two catalogs, with BLUETTI's Apex 300 at #2 of 39. Solar generator scoring is solar input per watt-hour of storage plus the MPPT ceiling.

From the test desk
“Same $209, same warranty, same 30dB noise floor — but at that identical price, capacity and speed go to the Elite 30 V2 while weather resistance goes to the RIVER 3, which carries an IP54 rating the Elite 30 simply doesn't have.”
“Two hundred ten dollars buys exactly double the capacity — 1,024 extra watt-hours at 21 cents apiece — which is why the AC200L clears an 8-hour blackout the DELTA 3 Plus can't.”
“Near-identical 288Wh twins, but the Elite 30 V2 is $70 cheaper with a higher surge — the RIVER 3 Plus charges $70 more for one thing the BLUETTI can't do: grow past 288Wh.”
“The Elite 200 V2 costs $350 more and then spends the next several years earning it back: exactly twice the cycle life, roughly double the capacity, seven cents a kilowatt-hour instead of eighteen.”
“Same-size battery, half the rated lifespan, and $498 more — the DELTA 2 Max has to justify its price on surge, charging, and an expansion port, because the cheaper Elite 200 V2 wins everywhere those three don't apply.”
“$100 more money buys 966Wh more battery and 2,000 more charge cycles, which is why the Elite 300 costs half as much per lifetime kWh to own — $0.06 against the DELTA 3 Max Plus's $0.12 — even though it's the pricier unit on the shelf.”

08 · Ecosystem and lock-in
What you commit to with the first purchase
The real question behind a brand-level search is which proprietary ecosystem to commit to. Expansion batteries do not cross brands, so the second purchase is decided by the first. These are the terms of that commitment as the catalogs stand today.

EcoFlow15 of 21 units
BLUETTI8 of 27 units
Good to knowEcoFlow's non-expandable units are DELTA 3 Ultra, RIVER 2 Pro, RIVER 2 Max, RIVER 2 and 2 more; BLUETTI's are Premium 200 V2, AC180P, AC70P, Elite 10 Mini and 15 more. Not expanding is only a con if you would have expanded.
Largest system either brand sells
EcoFlow18.4 kWh
BLUETTI39.7 kWh
Good to knowThe ceilings are the largest systems each brand sells, and the big ones are installs, not things you carry. Compare them only if you are actually building a stack.
Cost per added watt-hour when expanding
EcoFlow$0.30 per Wh added · base $0.68
BLUETTI$0.34 per Wh added · base $0.61
Good to knowOn both sides an expansion watt-hour costs well under a base watt-hour, because the base unit is where the inverter and electronics live. Only packs our catalog prices as SKUs are counted.

Retired this year, and what replaces it
Models that left each brand’s own store this year, and what we link instead. We verify a retirement on the maker’s storefront, never on a retailer’s stock page, and every retirement below has a named successor. We do not print release dates, because merchant timestamps reset when a store is rebuilt and are not a record of when a product shipped.
EcoFlow retired 3 models this year: the DELTA 3 1000 Air (successor DELTA 3 Classic), the RIVER 3 MAX PLUS (successor RIVER 2 Pro) and the RIVER 3 MAX PLUS WIRELESS (successor DELTA 3 Classic).
Retired
Successor
DELTA 3 1000 Air → DELTA 3 Classic
EcoFlow has discontinued the DELTA 3 1000 Air — it has left EcoFlow's own store and our price tracking, though remaining retailer stock may linger. Our recommended replacement is the EcoFlow DELTA 3 Classic: the same 1kWh class, with an 1,800W inverter to the Air's 500W.
Retired
Successor
RIVER 3 MAX PLUS → RIVER 2 Pro
EcoFlow no longer sells the RIVER 3 Max Plus. At this size the closest unit EcoFlow still sells is the RIVER 2 Pro — 768Wh with a stronger 800W inverter, typically for less money. If you'd rather step up in capacity, the DELTA 3 Classic (1,024Wh, 1,800W) is the move.
Retired
Successor
RIVER 3 MAX PLUS WIRELESS → DELTA 3 Classic
EcoFlow has discontinued the RIVER 3 Max Plus Wireless. Our recommended replacement is the DELTA 3 Classic — the same 1kWh-class capacity with a 1,800W inverter to this unit's 600W, usually for less money. You do give up the built-in wireless charging pad.
BLUETTI retired nothing in our tracking window; its lineup churn shows up as new releases rather than removals.
- No retirements recorded.

13 · FAQ
EcoFlow or BLUETTI: the questions people ask
Is EcoFlow better than BLUETTI?
Not as a brand. Of the 202 model-vs-model head-to-heads we have written, EcoFlow wins 122 and BLUETTI wins 76; EcoFlow leads between 1 and 2 kWh and above 5 kWh. Pick the capacity first, then the pair.
Which brand is more reliable, EcoFlow or BLUETTI?
We cannot measure failure rates. What we can measure: LFP share (100% against 96%), median rated cycles (3,000 against 3,500) and median warranty (5 against 5 years). Owner reports on durability and support are tallied in the Voices section.
Can I use BLUETTI expansion batteries with EcoFlow, or the other way round?
No. Expansion batteries are proprietary on both sides, which is why the first purchase decides the second. The ecosystem table quotes the cost per added watt-hour where our catalog prices the packs.
Which is cheaper per watt-hour, EcoFlow or BLUETTI?
On today's typical prices the medians are $0.56 for EcoFlow and $0.58 for BLUETTI across the whole catalog, so EcoFlow is cheaper overall.
Which brand discounts more often?
BLUETTI: 20 EcoFlow price drops against 41 for BLUETTI over the same 53 days. The deepest cuts were the RIVER 3 MAX at 27.3% and the AC50B at 30.1% under typical price.
Which has the better UPS mode?
EcoFlow lists a UPS mode on 100% of current units, BLUETTI on 96%. The ecosystem table counts how many on each side are rated at 10 ms or faster; a listed figure is a spec, not a test.
Are EcoFlow and BLUETTI the same company?
No. EcoFlow Technology was founded in Shenzhen in 2017 by former DJI battery engineers. BLUETTI is the power-station brand of Shenzhen-based PowerOak.
How these numbers were made
Instruments were computed on 2026-09-08 from the 23 EcoFlow and 45 BLUETTI listings in our catalog, excluding retired units and counting each stack configuration once. Prices are the typical prices from our price tracking (23,158 captures, 2026-07-17 to 2026-09-07), not spot or list prices. The head-to-head record counts only published head-to-heads between the two brands; pairs involving a retired unit are excluded from the live tally. Bench verdicts use the same PowerScore benches as our buying guides, ranked over the two brands’ current units only. Release dates are held back on purpose.
