Record tracks one inverter plus one battery. EcoFlow publishes the components at 31.7kg and 50.7kg; the stored 82.4kg is their transparent configuration sum, not a separately published package weight.
Regional source note: Some specs are cross-checked against official regional pages (ca.ecoflow.com: EcoFlow DELTA Pro Ultra CA specification table). Regional SKUs can differ; verify the manufacturer page for your market before purchase or emergency planning.

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.

Conservative assumes harder conditions; optimistic assumes favorable conditions.

  • This is an estimate. Real runtime changes with load, temperature, battery age, AC/DC output, and device behavior.

Rated Wh is reduced by efficiency, reserve, battery health, and temperature before it is divided by average load.

Source-Backed Next Steps

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 5,600 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.
