Goal Zero Yeti 1500X
1516 Wh · 2000 W output · NMC · $1999
✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
The previous-generation flagship. Its NMC battery is the catch — far fewer cycles than the LiFePO4 units now around it, including its own replacement.
Best for: Only at a steep discount against the newer LiFePO4 Yeti 1500.
What we like
- 1,516Wh with 2,000W output
- Lighter than the new LiFePO4 1500
Where it falls short
- NMC chemistry — roughly 500 cycles vs 4,000 for the new 1500
- 180-minute recharge is slow
- Only a 2-year warranty
