Goal Zero Yeti 1000X
983 Wh · 1500 W output · NMC · $1199
✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
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.
What we like
- 1,500W output, expandable
- App monitoring
Where it falls short
- NMC — ~500 cycles vs 4,000 for the new Yeti 1000
- 2-year warranty
