Goal Zero Yeti 1000 vs EcoFlow DELTA mini
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 mini costs $600 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1000 holds 12% more energy (988Wh vs 882Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1000 has 1500W more surge headroom (3600W vs 2100W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA mini is 11.7 lb lighter (23.6 lb vs 35.3 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 1.47 for the EcoFlow DELTA mini. 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
A compact NMC unit with a surprisingly strong 1,400W output for its size — but the 800-cycle battery means it won't age like the LiFePO4 field.
Best for: Buyers who want strong output in a light unit and won’t cycle it daily.
Where it falls short:
- NMC — ~800 cycles
- 2-year warranty, 300W solar input
