Goal Zero Yeti 300 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 300 costs $800 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Max 2000 holds 579% more energy (2016Wh vs 297Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Max 2000 has 2800W more surge headroom (3400W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 300 is 34.3 lb lighter (13.7 lb vs 48 lb).
- Goal Zero Yeti 300 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Goal Zero Yeti 300 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.
Goal Zero's compact entry: rugged and IPX4-rated, but you pay a premium over similar-capacity rivals for the drop-and-splash toughness.
Best for: Overlanders and job sites where the unit gets wet and knocked around.
Where it falls short:
- 350W output runs devices, not appliances
- $299 for 297Wh is pricey per watt-hour
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
