What it can run
Generators are sized in watts. Running watts are what the unit can supply continuously; starting watts are a short surge for motors and compressors. The Westinghouse Outdoor Power WGen9500DFc - Dual Fuel is rated at 12,500 W running.

Fuel and runtime
The sources we read do not give both a tank size and a runtime for this model, so we do not calculate a fuel burn rate.
Multi-fuel units usually produce less power on propane or natural gas than on gasoline; the maker's per-fuel ratings are the ones to size against.
Connecting it to a home
The listing mentions a transfer-switch- or RV-style outlet. To power home circuits you need a rated transfer switch or interlock and an inlet, matched to this generator's outlet and amperage, installed by a licensed electrician.
Check the pairing in the generator ↔ transfer-switch compatibility matrix.
Safety and placement
This listing mentions a carbon monoxide shutoff or sensor, which is a useful backup — not a substitute for placing the generator outdoors and keeping working CO alarms inside.
