Fuel and runtime
The maker states a 6.6-gallon tank and up to 13 hours at the stated load, which implies about 0.51 gallons per hour at that load.
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.
