Goal Zero Yeti 3000X 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 $2600 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 3000X holds 244% more energy (3032Wh vs 882Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 3000X has 1400W more surge headroom (3500W vs 2100W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA mini is 46.1 lb lighter (23.6 lb vs 69.75 lb).
- EcoFlow DELTA mini is rated for 800 cycles vs 500 — meaningful if you cycle it daily.
Goal Zero Yeti 3000X
A large-capacity unit held back by aging NMC cells. The capacity is real; the cycle life and charge speed are a generation behind.
Best for: Occasional-use backup where low cycle count won't bite.
Where it falls short:
- NMC — ~500 cycles against 4,000 for LiFePO4 rivals
- 69.75 lb and a 4-hour recharge
- 2-year warranty
EcoFlow DELTA mini
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
