Goal Zero Yeti 700 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
Goal Zero Yeti 700 costs $300 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Max 2000 holds 198% more energy (2016Wh vs 677Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Max 2000 has 2400W more surge headroom (3400W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 700 is 27.7 lb lighter (20.3 lb vs 48 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.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA Max 2000. Its NMC cells are rated for 800 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
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
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
