Goal Zero Yeti 300 vs EcoFlow DELTA 1300
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 $700 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 1300 holds 324% more energy (1260Wh vs 297Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 1300 has 2700W more surge headroom (3300W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 300 is 17.2 lb lighter (13.7 lb vs 30.9 lb).
- Goal Zero Yeti 300 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Goal Zero Yeti 300 is rated for 4,000 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA 1300. Its NMC cells are rated for 800 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
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
The original DELTA that put EcoFlow on the map. Fast-charging and high-surge for its day, but the NMC battery and lack of USB-C now show its age.
Best for: Bargain hunters who find it heavily discounted.
Where it falls short:
- NMC — ~800 cycles
- No USB-C PD
- 2-year warranty
