EcoFlow DELTA Max 2000
2016 Wh · 2400 W output · NMC · $1099
✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
The previous-generation 2kWh EcoFlow. Still capable and expandable, but its NMC cells and 800-cycle rating are a real step below the LiFePO4 DELTA 3 that replaced it.
Best for: Only at a steep discount against the DELTA 3 Max.
What we like
- 2,016Wh, expandable
- 2,400W output
- Six AC outlets
Where it falls short
- NMC — roughly 800 cycles vs 4,000 for the DELTA 3 Max
- 2-year warranty
