EcoFlow DELTA Pro 3 vs Goal Zero Yeti 1000X
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 1000X costs $2500 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro 3 holds 317% more energy (4096Wh vs 983Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro 3 has 5000W more surge headroom (8000W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1000X is 81.3 lb lighter (31.68 lb vs 113 lb).
- EcoFlow DELTA Pro 3 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA Pro 3 is rated for 4,000 cycles vs 500 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the Goal Zero Yeti 1000X. Its NMC cells are rated for 500 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
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
The older X-series 1kWh. Rugged and expandable, but its Li-ion cells and 2-year warranty look dated next to the LiFePO4 6th-gen Yeti 1000.
Best for: Only at a discount against the newer LiFePO4 Yeti 1000.
Where it falls short:
- NMC — ~500 cycles vs 4,000 for the new Yeti 1000
- 2-year warranty
