The short answer
Goal Zero Yeti 300 costs $3400 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro 3 holds 1279% more energy (4096Wh vs 297Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro 3 has 7400W more surge headroom (8000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 300 is 99.3 lb lighter (13.7 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 300
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
