Decision summary

Where this model earns its place

Best fitMulti-load outage plans that need more inverter headroom than the 1kWh class.
Main compromiseAt roughly 50 lb, it is movable rather than genuinely carry-friendly.
Direct-price context$1,199 from the official manufacturer page. Promotions can change.

How the record reads

Energy, output, and the appliance are three separate gates

The battery decides duration. The inverter decides whether a load can run and start. The appliance decides the voltage, connection, and surge demand that must be met.

Refrigerator planning profile

An estimated 31.5 hours from the visible defaults

This calculation uses a 150W running load, 1,200W starting load, 33% duty cycle, 90% usable capacity, and 88% AC efficiency. It is planning math, not a measured refrigerator test.
