9,500 running watts, 12,500 at start-up

That's the running figure the listing states, on gasoline. Add up what has to run at once (fridge, freezer, sump pump, furnace blower) and the Westinghouse 12,500W Dual Fuel should have room to spare on paper; the motor that starts last, often the well pump, is the one to plan around.

What it has going for it

What changes on the night the power goes out

Gasoline or propane. Propane keeps for years in a sealed tank and won't gum up the carburetor between storms; gasoline gives you more watts. Propane is rated lower, so find that figure in the manual.

50 amp outlet. The big plug that feeds a 50 amp inlet box, a transfer switch or a 50 amp RV. One cord carries both legs of 240 V, which is how the well pump and the furnace get power without extension cords through a window.

Extension cords or a transfer switch?

Extension cords: run a heavy cord from the Westinghouse 12,500W Dual Fuel's 120 V outlets (GFCI-protected, per the listing) to the fridge and the freezer, and you're set for a night. Hard-wired loads like the furnace and the well pump can't join in that way.

A transfer switch: the listing names an L14-30R twist-lock and a 50 amp outlet, and the seller calls it transfer-switch ready. With an inlet box and a transfer switch or interlock wired by an electrician, one cord feeds the panel, furnace and well pump included. Book that visit before storm season, not during the outage.

Great for you if…

You want most of the house running, not just the fridge
You'd rather store propane tanks than cans of gas
You plan a transfer switch, or you own a 50 amp RV

Skip it if…

You want CO protection built in: the listing mentions no CO sensor
You need quiet power for a campsite: this is a big open frame
You'd rather wait for buyer reviews: none are captured for this listing yet

What Westinghouse promises

The seller states, word for word, in the Westinghouse 12,500W Dual Fuel listing:

9500 Running Watts and 12500 Peak Watts (Gasoline).
Features Two GFCI 120V 5–20R 20A Standard Household Receptacle, One Transfer Switch Ready 120V L14-30R 30A, and One RV Ready 120/240V 14–50R 50A.

That's the seller talking, not us. No listing tells you how it sounds at 2 a.m. under the bedroom window, or how it takes the well pump's surge.

Outlets, fuel and what's in the box

What the Westinghouse 12,500W Dual Fuel listing names:

9,500 running watts, 12,500 peak
Runs on gasoline and propane
Outlets named: 50 amp, L14-30R, GFCI 120 V
Sold as transfer-switch ready
Remote and electric start
6 gallon tank
457 cc engine

Read the manual for the fuel, the oil grade and what each outlet is rated for before the first start.

Price and cost per 1,000 running watts

$999 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each 1,000 running watts works out at about $105.16 (price ÷ stated running watts, our arithmetic). That puts it in the cheaper third of the 37 generators above 8,000 running watts we have a price and a stated running figure for.

Add the hookup to the budget: a heavy cord, an inlet box and an electrician's visit for the transfer switch or interlock.

The button opens the exact listing (ASIN B07Q1DLKBG), where today's price, stock and seller apply.

A better fit for your load list?

Want it quieter, or cleaner power for electronics? The Champion 11,000W Dual Fuel Inverter (7.8/10) is an inverter, per its listing.

Want to hook it to the gas line? The Westinghouse 13,500W Tri-Fuel (9.2/10) runs on gasoline, propane and natural gas.

Want a CO shutoff? The WEN 14,500W Tri-Fuel, CO Watchdog (7.8/10) names a CO sensor that shuts the engine off.

Our take

The verdict

The Westinghouse 12,500W Dual Fuel earns its place with 9,500 running and 12,500 peak watts and the choice of gasoline or propane. No buyer reviews yet, so the Westinghouse 12,500W Dual Fuel has to win you over on paper. The catch with this Westinghouse generator: no CO sensor in the listing, while most picks here have one. We'd pick the Westinghouse 12,500W Dual Fuel if you want most of the house running, not just the fridge; otherwise, put it next to the Champion 16,875W Tri Fuel first.

Living with it

Delivery day

Fill it with oil before the first start, then run it for a few minutes outside with a small load.

The first outage

Start it with the fob, let it warm up, then add loads one at a time, the biggest motor first. Propane or gas: decide before the storm and have the hose and the tank ready.

Between storms

Run it every month or so for 20 minutes and keep the battery charged. On propane you avoid stale gas in the carburetor; on gas, add stabiliser or run it dry before storage. Our maintenance schedule has the full list.

Upkeep

First oil change after the break-in hours in the manual (the hour meter counts them), then on schedule. Air filter and spark plug once a season, and a cover for the months it sits.

The one thing we'd check first

Before the Westinghouse 12,500W Dual Fuel goes in your cart, check your hookup: 9,500 running watts are only useful through an inlet box and a transfer switch or interlock, so price in the electrician.

Before you buy

Your load list

9,500 running watts and 12,500 at start-up, per the listing. Write down what has to run at the same time, add the biggest motor surge (well pump, sump pump, AC), and let our sizing calculator do the sums.

How it reaches the house

Ask an electrician to quote an inlet box plus a transfer switch or an interlock before you buy, so the total is no surprise. Our interlock vs transfer switch guide compares the two.

Where it will run

Outside only, about 20 ft from doors, windows and vents, exhaust pointing away. Pick the spot now, before the storm. Our CO safety and placement guide has the details.

Fuel for three days

Gasoline goes stale in a few months without stabiliser; propane keeps. Check the propane rating in the manual if propane is your plan. Our fuel storage guide covers storage.

Frequently asked questions

Is the Westinghouse 12,500W Dual Fuel any good?

We rate it 7.6/10 (very good). The rating comes from its documented listing alone, as no customer-review record is captured yet.

How many watts does the Westinghouse 12,500W Dual Fuel deliver?

The listing or manual states 9,500 W running and 12,500 W peak, usually for gasoline. Size your load list against the running watts and keep the peak for motor starts; propane and natural gas ratings are lower. These are the seller's figures, not our measurements (our sizing calculator turns your loads into a running and peak pair).

Which fuels does the Westinghouse 12,500W Dual Fuel run on?

The listing names gasoline and propane. Output differs by fuel, so check the per-fuel running watts in the manual and whether the hoses you need come in the box. Run it outdoors only, away from doors, windows and vents.

What do you get with the Westinghouse 12,500W Dual Fuel?

Its listing states 9,500 running watts (12,500 at start-up), the choice of gasoline or propane, a 50 amp outlet for an inlet box or an RV and remote start from a key fob. These are the seller's figures, not our measurements: how loud it is in your driveway and how it handles your well pump's surge can't be read from a listing.

What should I check before ordering the Westinghouse 12,500W Dual Fuel?

Your load list: 9,500 running watts and 12,500 at start-up, per the listing. Write down what has to run at the same time, add the biggest motor surge (well pump, sump pump, AC), and let our sizing calculator do the sums. How it reaches the house: ask an electrician to quote an inlet box plus a transfer switch or an interlock before you buy, so the total is no surprise. Our interlock vs transfer switch guide compares the two. Where it will run: outside only, about 20 ft from doors, windows and vents, exhaust pointing away. Pick the spot now, before the storm. Our CO safety and placement guide has the details. Fuel for three days: gasoline goes stale in a few months without stabiliser; propane keeps. Check the propane rating in the manual if propane is your plan. Our fuel storage guide covers storage.
