What will a 12,500-watt generator run?
The Westinghouse WGen9500TFc EFI delivers 9,500 W continuously and up to 12,500 W for a few seconds to start motors on gasoline. On propane, the manufacturer rates it at 8,500 running watts (11,200 W starting), 11% less. On natural gas: 7,500 running watts (9,500 W starting). It handles 14 of the 14 loads on our typical list one at a time; add up the running watts of everything you run together, plus the extra starting watts of the biggest motor.

Fuel tank and runtime
The fuel tank holds 6.6 gallons of gasoline. The manufacturer quotes 15 hours at a quarter load. At half load, it runs about 10 hours on a full tank. That is about 0.66 gallon per hour at half load, or 16 gallons for a full day of running, so plan your fuel storage for a multi-day outage. On propane, a standard 20 lb tank holds about 4.7 gallons of LP; propane does not go stale, which makes it the easiest fuel to stock.
74 dB(A): how loud is it?
The manufacturer rates the Westinghouse WGen9500TFc EFI 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.
Outlets and home connection
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. 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.
Starting, safety 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 CARB compliant, so it can be sold in California. The warranty runs 3 years (residential use).
Typical price $1,200–$1,800: good value per watt?
Relative to its running watts, the Westinghouse WGen9500TFc EFI scores 7.9/10 on value: a good result. Generator prices on Amazon move a lot, especially before hurricane season: check the current price before you buy.
