Fuel and runtime
The maker states a 4.7-gallon tank and up to 11 hours at the stated load, which implies about 0.43 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
We did not find a carbon monoxide shutoff listed for this model in the sources we read, which makes outdoor placement and working CO alarms even more important.
