EcoFlow DELTA 3 Max vs Goal Zero Yeti 3000X
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 3 Max costs $2100 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 3000X holds 48% more energy (3032Wh vs 2048Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Max has 1300W more surge headroom (4800W vs 3500W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow DELTA 3 Max is 14.6 lb lighter (55.1 lb vs 69.75 lb).
- EcoFlow DELTA 3 Max uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA 3 Max is rated for 4,000 cycles vs 500 — meaningful if you cycle it daily.
The Goal Zero Yeti 3000X is poor value on paper: 0.95 Wh per dollar versus 1.86 for the EcoFlow DELTA 3 Max. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
The value leader in the 2kWh class. Same 4800W surge as the DELTA 2 Max at $500 less, with 1000 more cycles.
Best for: Home backup buyers who want compressor-starting surge without paying flagship prices.
Where it falls short:
- 55 lb is a two-hand lift
- Only marginally lighter than heavier rivals
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
