Third-party measured tests

These are published third-party measurements for this model. The delta compares measured delivered Wh with WattRunTime's default no-reserve planning estimate for the same output path; it is not a new measurement.

Runtime Starting Points

These are formula estimates using the tracked capacity, a 10% reserve, and each scenario's default wattage and duty cycle. They are planning starters, not measured runtimes.

Good fit when

Capacity is in a larger outage/RV class, so the useful question is usually output limits, recharge speed, and weight rather than watt-hours alone.
Tracked AC output is high enough for many household plug-in loads, but surge still needs a separate check.
USB-C output is tracked at laptop-class power, useful for direct DC charging when the device supports it.
Tracked solar input is 1,600 W before panel, weather, angle, and controller losses.

Watch out for

Surge output is tracked, but device startup behavior should still be checked against the actual load.
Tracked weight is in a heavier class; plan where it will live before treating it as a grab-and-go station.
