Our verdict
Adds 600W of continuous output and doubles surge headroom over the standard Max, for $200. Worth it only if you're running heavy loads.
Best for: Workshops and job sites where tool startup surge is the constraint.
What we like
- 6000W surge starts almost any household appliance
- 3000W continuous handles power tools
- Same 2048Wh and 4000 cycles
Where it falls short
- $200 premium is wasted if your loads are under 2400W
- 57 lb
