3600 Wh · 3600 W output · LiFePO4 · $3199
✅ Specs verified against the manufacturer's official listing — source · Last checked
Our verdict
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.
What we like
- 3600Wh at frequently discounted pricing
- 7200W surge still handles heavy loads
- Huge ecosystem of expansion batteries
Where it falls short
- 99 lb and 165-minute recharge — both beaten by the Pro 3
- Aging platform; expect it to be phased out
