Goal Zero Yeti 700 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 $200 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA mini holds 30% more energy (882Wh vs 677Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA mini has 1100W more surge headroom (2100W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 700 is 3.3 lb lighter (20.3 lb vs 23.6 lb).
- Goal Zero Yeti 700 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Goal Zero Yeti 700 is rated for 4,000 cycles vs 800 — meaningful if you cycle it daily.
The Goal Zero Yeti 700 is poor value on paper: 0.85 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 largest of the rugged compacts. Still not an appliance unit — 600W of output caps what it can drive — but a durable mid-size companion.
Best for: Rugged off-grid use where durability outranks running heavy loads.
Where it falls short:
- 600W output rules out compressors and heaters
- 20.3 lb is heavy for 677Wh
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
