EcoFlow DELTA mini vs Goal Zero Yeti 1000X
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 1000X holds 11% more energy (983Wh vs 882Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1000X has 900W more surge headroom (3000W vs 2100W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA mini is 8.1 lb lighter (23.6 lb vs 31.68 lb).
- EcoFlow DELTA mini is rated for 800 cycles vs 500 — meaningful if you cycle it daily.
The Goal Zero Yeti 1000X 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.
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
The older X-series 1kWh. Rugged and expandable, but its Li-ion cells and 2-year warranty look dated next to the LiFePO4 6th-gen Yeti 1000.
Best for: Only at a discount against the newer LiFePO4 Yeti 1000.
Where it falls short:
- NMC — ~500 cycles vs 4,000 for the new Yeti 1000
- 2-year warranty
