Goal Zero Yeti 500 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 $100 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA mini holds 77% more energy (882Wh vs 499Wh), 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 500 is 10.7 lb lighter (12.9 lb vs 23.6 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.
The Goal Zero Yeti 500 is poor value on paper: 0.71 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.
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
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
