Runtime and fuel
The fuel tank holds 6.6 gallons of gasoline. The manufacturer quotes 12 hours at a quarter load. At half load, count on roughly 7 hr 30 min (our estimate from the quarter-load figure). That is about 0.88 gallon per hour at half load, or 21 gallons for a full day of running, so plan your fuel storage for a multi-day outage.
74 dB(A): how loud is it?
The manufacturer rates the Westinghouse WGen9500c at 74 dB(A), usually measured at 23 feet (7 m) and a light load. That is loud, like a lawn mower: place it as far from the house and the neighbors as the cords allow.
Can you connect it to your house?
Its panel offers 4 × 120 V household outlets (5-20R), L14-30R 30 A 120/240 V twist-lock, 14-50R 50 A 120/240 V, USB ports. The 14-50R outlet supplies 120/240 V, which is what a manual transfer switch or an interlock kit with a power inlet box connects to, installed by a licensed electrician. Never backfeed the house through a wall outlet.
Safety features and warranty
It starts with a remote key fob or the electric push-button, with a recoil cord as backup. A CO shutoff sensor stops the engine if carbon monoxide builds up around it; it does not replace distance (20 feet from the house) and CO alarms indoors. It is listed as EPA compliant; check California availability if you live there. The warranty runs 3 years (residential use).
Typical price $800–$1,200: good value per watt?
Relative to its running watts, the Westinghouse WGen9500c scores 9.4/10 on value: one of the best results in our catalogue. Generator prices on Amazon move a lot, especially before hurricane season: check the current price before you buy.
