EcoFlow DELTA 2 Max vs Goal Zero Yeti 300
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 300 costs $1300 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 2 Max holds 590% more energy (2048Wh vs 297Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 2 Max has 4200W more surge headroom (4800W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 300 is 36.3 lb lighter (13.7 lb vs 50 lb).
- Goal Zero Yeti 300 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
The surge sleeper. At 4800W it starts loads that stations twice its price can't — and most spec sheets bury that number behind the X-Boost figure.
Best for: Home backup where something with a compressor — fridge, freezer, window AC — has to start reliably.
Where it falls short:
- 50 lb is heavy for its capacity
- Marketing leads with the 3400W X-Boost number, which understates it
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
