EcoFlow DELTA 3 vs Goal Zero Yeti 1000
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
EcoFlow DELTA 3 costs $550 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 holds 4% more energy (1024Wh vs 988Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 is 6.6 lb lighter (28.7 lb vs 35.3 lb).
We'd skip the Goal Zero Yeti 1000 in this matchup. It costs $550 more than the EcoFlow DELTA 3 while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
The 1kWh class got a serious upgrade here. 3600W surge at $649 beats the older DELTA 2 on every axis that matters.
Best for: Anyone about to buy a DELTA 2 — this is the same money for materially better specs.
Where it falls short:
- Still only 1024Wh
- Solar input unchanged at 500W
The 6th-gen Yeti 1000 finally brings a real 2,000W inverter to Goal Zero's mid-size. Now it competes on output, not just toughness.
Best for: Buyers who want Goal Zero's ruggedness with real appliance-starting output.
Where it falls short:
- 35.3 lb for under 1kWh is heavy
- Premium price against lighter rivals
