Goal Zero Yeti 500 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 500 costs $400 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Max 2000 holds 304% more energy (2016Wh vs 499Wh), 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 500 is 35.1 lb lighter (12.9 lb vs 48 lb).
- Goal Zero Yeti 500 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Goal Zero Yeti 500 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.
A rugged, water-resistant unit for people who'll actually beat it up. You pay a premium over similar-capacity rivals for that durability.
Best for: Overlanders and job sites where the unit will get wet, dusty and knocked around.
Where it falls short:
- $699 for 499Wh is expensive per watt-hour
- Only a 2-year warranty vs 5 years from most rivals
- 120W solar input is very low
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
