What the DELTA 3 1000 Air actually runs
The load profiles every comparison on the site is scored on, computed for this unit alone: energy needed against the usable tank after inverter losses, and whether the inverter holds and starts the biggest single load.

Who it is for, and when a rival won instead
Each line is lifted from a written matchup where it decided the verdict, and links to the page it came from. Repeated across many matchups means it is the unit’s signature, not one author’s opinion.
Buy the DELTA 3 1000 Air if…
You want the lower cost per lifetime kilowatt-hour: $0.11 against the Jackery's $0.18.
Decided 20 matchups · read one →
Anyone who wants a light 22 lb desk UPS and doesn't need the extra output or an expansion path.
Decided 5 matchups · read one →
You want a quiet, fast-switchover UPS for a desk setup and don't need more than 500W continuous.
Decided 4 matchups · read one →
Your heaviest regular load is a laptop, monitor, router, or CPAP — nothing the 500W ceiling excludes.

A rival won when…
You want the option to expand capacity later and don't mind the fan noise as the tradeoff for it.
Decided 13 matchups · read one →
You want a modern laptop to charge at full speed over USB-C — 100W against the 1000 Air's 18W.

Reviewer consensus
1/4 positive excerpts, 4 sources
A focused home-office UPS unit — LFP, 10ms UPS, quiet and light — but low 500W output; now discontinued in favor of the DELTA 3.

From the test desk
“The DELTA 3 1000 Air is cheaper per lifetime kWh, $0.11 against $0.14, and that's the one honest point in its favor.”
“The DELTA 3 1000 Air is still the pick for light, steady loads — a CPAP, a laptop, a router, a tailgate speaker rig — because its bigger 960Wh tank is what wins Tailgate Party outright and leaves more headroom on CPAP…”
“Take the DJI Power 1000, unless your loads are already light and stationary.”

Questions people ask
Is the DELTA 3 Classic really the successor to the DELTA 3 1000 Air?
Yes, per EcoFlow's own materials, which name the standard DELTA 3 as the 1000 Air's replacement at 1,024Wh and 1,800W [A4] — specs the Classic matches exactly. This comparison is effectively an old model against its own manufacturer-named upgrade.
Is the DELTA 3 1000 Air cheaper to own?
By cost-per-lifetime-kWh, yes: $0.11 against the Classic's $0.14. But by cost-per-warranty-year the Classic wins, $86 against $155, because its warranty runs two and a half times longer. Which number matters depends on whether you're pricing energy delivered or years of coverage.
Does the DELTA 3 1000 Air support battery expansion?
No — it's a sealed unit for the life of ownership. The Classic accepts EcoFlow's expansion batteries, so its capacity can grow later without buying an entirely new base unit.
Is the DELTA 3 1000 Air still available new?
No — EcoFlow has discontinued it, with the standard DELTA 3 as the closest currently-sold successor [A4]. Units already in the field keep their original warranty terms, but expect long-term parts and support to lean on the newer model rather than this one.
EcoFlow DELTA 3 1000 Air vs DJI Power 1000 — which should I buy?
The Power 1000 for most buyers: its 2,200W continuous inverter and 4,400W surge are 4.4 times the 1000 Air's, backed by more solar (800W against 500W), more cycle life (4,000 against 3,000), and a longer warranty (5 years against 2), for $390 more. Take the 1000 Air instead if you're protecting light electronics only — a router, a desktop, a CPAP — where its 10ms switchover and $309 price make it the better fit.
