EcoFlow DELTA 3 vs Goal Zero Yeti 1500
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 $1050 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1500 holds 47% more energy (1505Wh vs 1024Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 is 24.1 lb lighter (28.7 lb vs 52.75 lb).
The Goal Zero Yeti 1500 is poor value on paper: 0.89 Wh per dollar versus 1.58 for the EcoFlow DELTA 3. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
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 new-for-2026 LiFePO4 Yeti 1500 — a big durability and cycle-life upgrade over the older 1500X it replaces.
Best for: Home backup buyers who want Goal Zero's build with modern battery chemistry.
Where it falls short:
- 52.75 lb — a two-hand lift
- 600W solar input is modest for the capacity
