Goal Zero Yeti 1000 vs EcoFlow DELTA Max 2000
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 Max 2000 costs $100 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Max 2000 holds 104% more energy (2016Wh vs 988Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1000 has 200W more surge headroom (3600W vs 3400W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1000 is 12.7 lb lighter (35.3 lb vs 48 lb).
- Goal Zero Yeti 1000 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Goal Zero Yeti 1000 is rated for 4,000 cycles vs 800 — meaningful if you cycle it daily.
The Goal Zero Yeti 1000 is poor value on paper: 0.82 Wh per dollar versus 1.83 for the EcoFlow DELTA Max 2000. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
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
The previous-generation 2kWh EcoFlow. Still capable and expandable, but its NMC cells and 800-cycle rating are a real step below the LiFePO4 DELTA 3 that replaced it.
Best for: Only at a steep discount against the DELTA 3 Max.
Where it falls short:
- NMC — roughly 800 cycles vs 4,000 for the DELTA 3 Max
- 2-year warranty
