EcoFlow DELTA Pro 3 vs Goal Zero Yeti 500
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 $3000 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro 3 holds 721% more energy (4096Wh vs 499Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro 3 has 7000W more surge headroom (8000W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 500 is 100.1 lb lighter (12.9 lb vs 113 lb).
EcoFlow DELTA Pro 3
The most complete large unit here. 4096Wh, 4000W, 8000W surge and 2600W of solar — it does everything the F3800 does with less weight.
Best for: Whole-home backup buyers who want maximum solar recharge speed.
Where it falls short:
- $3,699 is a serious investment
- Overkill unless you're backing up a whole home
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
