EcoFlow DELTA Pro 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 $2000 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 266% more energy (3600Wh vs 983Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 4200W more surge headroom (7200W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1000X is 67.3 lb lighter (31.68 lb vs 99 lb).
- EcoFlow DELTA Pro uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- EcoFlow DELTA Pro is rated for 3,500 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 previous-generation flagship, now mostly worth buying on discount. The Pro 3 beats it on nearly every axis.
Best for: Bargain hunters who find it steeply discounted against the Pro 3.
Where it falls short:
- 99 lb and 165-minute recharge — both beaten by the Pro 3
- Aging platform; expect it to be phased out
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
