What this unit is for
The outdoor-lifestyle brand that made "portable power station" a mainstream American purchase, and still optimizes for the buyer who does not want to research inverters.
Best suited to: A first power station that must be simple, safe and easy to live with. Less suited to: Buyers chasing maximum watt-hours per dollar, or maximum solar input.
Multi-day backup, off-grid and whole-home loads.
