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 $2500 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 621% more energy (3600Wh vs 499Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 6200W more surge headroom (7200W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 500 is 86.1 lb lighter (12.9 lb vs 99 lb).
- Goal Zero Yeti 500 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
Goal Zero Yeti 500
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
EcoFlow DELTA Pro
The previous-generation flagship, now mostly worth buying on discount. The Pro 3 beats it on nearly every axis.
Best for: Bargain hunters who find it steeply discounted against the Pro 3.
Where it falls short:
- 99 lb and 165-minute recharge — both beaten by the Pro 3
- Aging platform; expect it to be phased out
