Brand matchup
EcoFlow vs Goal Zero
The measured comparison: 54 model-vs-model head-to-heads, 21 EcoFlow and 14 Goal Zero 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.
Goal Zero is the Yeti: the name that sat on outdoor-store shelves before most of this category existed, still sold as part of a kit of panels, mounts and vehicle integrations. Its 14 current models run from 95 Wh to 6.1 kWh, mix chemistries (43% LFP), and cost $1.01 per watt-hour on the median model, with a 2-year warranty behind it.

02 · Measured strengths and trade-offs
Where each brand is strong, and where it is not
The pros and cons, except that every one is a measurement: generated from the catalog, the price captures, the reviews and our head-to-heads, and scoped to the sizes where it holds.

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; Goal Zero's sharpest notes are value and durability, with charging speed and build quality 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
- Goal ZeroCharging speed
“I’m staying with my goal zero 1400 because I can recharge it from below 20% to 100% in 3 hour with their 25 amp fast charger from goal zero.”

“For those who are considering an all-in-one portable, this is an Aha Moment! I have a Yeti 3000X I bought two years ago and the compatible expansion batteries are lead acid! I do like the built-in wheels for bugging out, but C’mon! Thanks, Will.”

From the test desk
“The Yeti 3000X asks $1,701 more than the DELTA 3 Ultra for a battery rated to give out eight times sooner.”
“The DELTA 3 Max Plus is $125 cheaper and still out-cycles the Yeti 1500X eight to one, which is why it costs 12 times less per kilowatt-hour over its life.”
“Everything on this page except the bathroom scale points at the DELTA 3 Ultra, and the Yeti 1500X's 500 rated cycles against 4,000 is why.”
“Buy the Yeti PRO 8000 and you'll carry less through the door on install day; buy the DELTA Pro Ultra and you'll pay less for every kilowatt-hour, for as long as you own it.”
“The DELTA Pro 3 used to cost more than the Yeti 3000X and still won on the math; now it's $601 cheaper and wins by more, which leaves the Yeti with exactly one argument left — weight.”
“EcoFlow tells you the DELTA 2 hits 50dB under load; Goal Zero won't say what the Yeti does — and only one of those two facts should make you nervous.”

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.

Good to knowEcoFlow's non-expandable units are DELTA 3 Ultra, RIVER 2 Pro, RIVER 2 Max, RIVER 2 and 2 more; Goal Zero's are Yeti 700, Yeti 500, Yeti 300, Yeti 500X and 5 more. Not expanding is only a con if you would have expanded.
Largest system either brand sells
EcoFlow18.4 kWh
Goal Zero8 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
Goal Zero$0.50 per Wh added · base $1.00
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.
Models with a UPS mode
EcoFlow21 of 21 · 12 at 10 ms or under
Goal Zero6 of 14 · 0 at 10 ms or under
Good to knowEcoFlow's units without a UPS mode: none. Goal Zero's: Yeti 6000X, Yeti 3000X, Yeti 1500X, Yeti 1000X and 4 more. A listed switchover figure is a spec, not a test; our UPS tiers grade the stated milliseconds.

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.
Goal Zero retired nothing in our tracking window; its lineup churn shows up as new releases rather than removals.

13 · FAQ
EcoFlow or Goal Zero: the questions people ask
Is EcoFlow better than Goal Zero?
Not as a brand. Of the 54 model-vs-model head-to-heads we have written, EcoFlow wins 53 and Goal Zero wins 1; EcoFlow leads under 500 Wh, between 1 and 2 kWh and between 2 and 5 kWh. Pick the capacity first, then the pair.
Which brand is more reliable, EcoFlow or Goal Zero?
We cannot measure failure rates. What we can measure: LFP share (100% against 43%), median rated cycles (3,000 against 500) and median warranty (5 against 2 years). Owner reports on durability and support are tallied in the Voices section.
Can I use Goal Zero 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 Goal Zero?
On today's typical prices the medians are $0.56 for EcoFlow and $1.01 for Goal Zero across the whole catalog, so EcoFlow is cheaper overall.
Which brand discounts more often?
EcoFlow: 20 EcoFlow price drops against 1 for Goal Zero over the same 53 days. The deepest cuts were the RIVER 3 MAX at 27.3% and the Sherpa 100PD at 25.0% under typical price.
Which has the better UPS mode?
EcoFlow lists a UPS mode on 100% of current units, Goal Zero on 43%. 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 Goal Zero the same company?
No. EcoFlow Technology was founded in Shenzhen in 2017 by former DJI battery engineers. Goal Zero is a Utah company owned by NRG Energy since 2014.
How these numbers were made
Instruments were computed on 2026-09-08 from the 23 EcoFlow and 15 Goal Zero 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.
