Westinghouse iGen400s Runtime Calculator

Use this source-linked record to estimate runtime from tracked capacity, output, charging, and weight fields. Unknown specs stay unknown until an official or manufacturer-grade source confirms them.

The 100W USB-C value is the highest published single-port ceiling, not a sum across the three 30W ports and one 100W port. Product weight converts the official 5.53 lb figure to 2.51 kg. The formal specification's 200W rated / 400W peak pair is stored; the manual's separate 300W intended-use wording is not substituted for either rating.

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 a compact class; use it for small electronics and short essentials rather than high-wattage appliances.
  • Tracked AC output is 200 W, so high-draw appliances and tools need careful filtering.
  • USB-C output is tracked at laptop-class power, useful for direct DC charging when the device supports it.
  • Tracked solar input is 100 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.
