Westinghouse iGen1000s 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.

DC stores the manual's explicit 300W combined DC ceiling rather than summing individual ports. Solar stores the manual's explicit 400W input limit. USB-C stays unknown because the manual names two USB-C ports but publishes no per-port watt rating; the separate 28W figure belongs to fast-charge USB-A and is not borrowed.
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 mid-size planning class that can cover many overnight or essential-load scenarios when reserve and efficiency are included.
- Tracked AC output is 1,500 W, so high-draw appliances and tools need careful filtering.
- Tracked solar input is 400 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.
- Still unknown in the source-backed record: usb-c output.
- Confidence is not marked verified; keep the linked source context visible before making a purchase or emergency plan.
