Brand matchup
EcoFlow vs DJI
The measured comparison: 21 model-vs-model head-to-heads, 21 EcoFlow and 3 DJI 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.
DJI came in from the air: the drone maker's Power line is 3 units between 512 Wh and 2 kWh, fitted with SDC ports that fast-charge its own drone batteries, and specified hard where it plays, with 4,000-cycle LFP cells and 879 W of solar input per kWh on the median model. It skips the very small and the very large and concentrates on the middle of the range.

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.

Owners knock EcoFlow hardest on availability and durability and praise its runtime and charging speed; DJI's sharpest notes are durability and the app, with weight and fan noise on the positive side. Bars count paraphrased claims; a claim is what a commenter said, not a verified fact.
Owners, in their own words
Verbatim, as the comment stands today; re-fetched 2026-09-07. Owner reports are what buyers say, not what we measured.
- EcoFlowSolar input
“So many reviewers echo the features the manufacture posts so they sound more like salesmen instead of real informative reviews but not the Professor and I thank you. I had this one in my cart all morning and I'm removing it now. As for the solar input I have two strings of about 2500 watts each at around 125 volts that I use to charge two Delta Pro so the 1600 watt limit would work out for me since I already have the setup for it but the proprietary ports don't make sense in 2025.”
- EcoFlowDurability and failures
“I bought a Delta Pro Oct 2023 it died June 2024. Support was good. It took 2.5 weeks to get a refurb.”
- EcoFlowCapacity and runtime
“As for the UPS comment, anyone who's ever worked IT knows a UPS provides consistent, CLEAN power to the load to guarantee it stays up, regardless of what happens at the wall. Surges, power dips, voltage drops, frequency modulation, doesn't matter. For the same reason all these power lifting modes don't work with computers, ups's are supposed to validate incoming voltage. Ecoflow confirmed their low voltage cutoff is 70v. Most electronics are shutting off or getting damaged below 90-95v, so the grid can provide a solid 75v for 20 minutes and the power station will pass through all that dirty power. Or hell, none check for frequency modulation. it will happily put through a 61hz sine wave. I use my power station as an extended runtime for my ups, not in replacement. My lead acid ups has about 8 minutes of runtime on my desktop. The delta 2 max the ups is plugged into ups that to 4 hours.”Show the full comment
- DJIApp and firmware
“UPDATE: I confirmed that a new firmware update fixes the inverter voltage output on the Power 2000! The power station now outputs 120v on the inverter 👍 Awesome fix, DJI!”
- DJICharging speed
“bought and testified it CANNOT, 140W is out of its league. Could be why the power station wasn't tested to be 140W charging in the video.”
- DJICharging speed
“This vid is so informative Prof. Just speaking from my experience w/ DJI power tho, the 140W output worked pretty well with my Mac pro and one fast charging port is good enough for me.”

Reviewers knock EcoFlow most on support and idle drain and praise its durability and fan noise; DJI draws its sharpest notes on charging and takes clean marks on charging. Read the bars as where each brand gets argued about, not as a score.
From the test desk
“This isn't a smarter unit beating a dumber one - it's a 2,048Wh battery beating a 1,024Wh battery, for $750 more, and the entire verdict rides on whether you actually need the extra half.”
“DJI wants $300 more for the same battery, the same inverter, and the same warranty. That premium gets earned back by exactly two buyers: serious solar users and DJI drone pilots. Everyone else is buying the EcoFlow.”
“The DJI Power 2000 is the nicer machine; the EcoFlow DELTA 3 Max is the same 2,048Wh, 4,000-cycle battery for $500 less, and the battery is the part that does the work.”
“Same 2,048Wh tank, $350 apart: the DELTA 2 Max is the cheaper machine to buy and, by the lifetime-cost math, the cheaper one to own — DJI's extra cycle life and hush-quiet fans have to earn that gap on their own.”
“The DELTA 3 matches the DJI's 10ms UPS handoff and its quiet operation, then undercuts it by $180 and adds a five-year warranty — so the DJI's premium is left buying raw output and cycle count you rarely reach on a 1,024Wh box.”
“The $429 Classic out-scores the $699 DJI, matches it on 10ms UPS, quiet, and a sub-hour recharge, and costs the least to own here — so the DJI's premium buys a nicer shell and cycles you won't reach, not a better decision.”

“Big fan of Pecron. That 1500-watt inverter, 300 watts short? Should be able to run whatever kitchen countertop appliances with a unit of this size. Have 2 DJI 1000's and Delta 2 and 3 all cost less than $400 when on sale. If you can get by with the 1500-watt inverter, your good to go. Just a heads up to take the time to figure your needs. JMO.”

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.

11 · Lifecycle
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.
DJI retired 1 model this year: the Power 1000 (successor Power 1000 V2).
Retired
Successor
Power 1000 → Power 1000 V2
DJI has superseded the Power 1000 with the Power 1000 V2 — same $699, with 2,600W output against 2,200W. The original may still be purchasable while stock lasts, but unless it is meaningfully discounted, buy the V2.

13 · FAQ
EcoFlow or DJI: the questions people ask
Is EcoFlow better than DJI?
Not as a brand. Of the 21 model-vs-model head-to-heads we have written, EcoFlow wins 12 and DJI wins 9; no capacity band produces a clear leader. Pick the capacity first, then the pair.
Which brand is more reliable, EcoFlow or DJI?
We cannot measure failure rates. What we can measure: LFP share (100% against 100%), median rated cycles (3,000 against 4,000) and median warranty (5 against 5 years). Owner reports on durability and support are tallied in the Voices section.
Can I use DJI 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 DJI?
On today's typical prices the medians are $0.56 for EcoFlow and $0.63 for DJI across the whole catalog, so EcoFlow is cheaper overall.
Which brand discounts more often?
EcoFlow: 20 EcoFlow price drops against 1 for DJI over the same 53 days. The deepest cuts were the RIVER 3 MAX at 27.3% and none on the DJI side under typical price.
Which has the better UPS mode?
EcoFlow lists a UPS mode on 100% of current units, DJI on 100%. 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 DJI the same company?
No. EcoFlow Technology was founded in Shenzhen in 2017 by former DJI battery engineers. DJI, the Shenzhen drone maker, entered power stations in 2024.
How these numbers were made
Instruments were computed on 2026-09-08 from the 23 EcoFlow and 3 DJI 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.
