Written from the listing's specs, not from our own use · How we rate

20,000 running watts (28,000 at start-up), a 50 amp outlet and built-in CO sensing: the Westinghouse 28,000W Gas covers what matters most in a generator. It makes most sense for whole-house backup through a transfer switch; we rate it 7.7/10 from its listing.

20,000 running watts, 28,000 at start-up

That's the running figure the listing states. Enough, on paper, for the fridge, the chest freezer and the sump pump at once, with the furnace or the well pump on top once a transfer switch is in. Hold the well pump's start-up surge against the peak before you count on it.

What it has going for it

What changes on the night the power goes out

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.

CO sensor. A sensor that watches the carbon monoxide around the unit, per the listing. Treat it as a backup: the generator still belongs outside, about 20 ft from doors and windows.

Extension cords or a transfer switch?

Extension cords: the cheapest start. The fridge, the freezer and a lamp plug into the 120 V outlets (GFCI-protected, per the listing); the furnace, the well pump and the water heater stay dark.

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 plan a transfer switch, or you own a 50 amp RV
Kids or pets in the house make CO safety a must

Skip it if…

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
You want propane as a backup fuel: the listing names gasoline only

What Westinghouse promises

The seller states, word for word, in the Westinghouse 28,000W Gas listing:

28,000 Peak Watts and 20,000 Running Watts.
Engineered with Low THD, So It's Safe for Sensitive Electronics.
Oil, Funnel, Setup Guide, and Manual to Get You Started Right Out of the Box.

The seller's claims, quoted as written; we haven't measured any of it. The noise on your driveway and the surge of your well pump are things you only find out at home.

Outlets, fuel and what's in the box

What the Westinghouse 28,000W Gas listing names:

Sold as transfer-switch ready
Remote and electric start

The manual for the Westinghouse 28,000W Gas has the final word on fuel, oil and outlet ratings.

Price and cost per 1,000 running watts

$3,799 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each 1,000 running watts works out at about $189.95 (price ÷ stated running watts, our arithmetic). That puts it around the middle of the 37 generators above 8,000 running watts we have a price and a stated running figure for.

Count the hookup in the budget too: a heavy cord, an inlet box and a transfer switch or interlock, wired by an electrician, are a separate bill.

A better fit for your load list?

Want propane as a backup fuel? The Westinghouse 28,000W Tri-Fuel (7.8/10) runs on gasoline, propane and natural gas.

Only the fridge and a few lights? The Westinghouse 5,000W Dual Fuel Inverter (9.2/10) is a 3,900 W inverter.

Our take

The verdict

What we'd buy the Westinghouse 28,000W Gas for is 20,000 running watts (28,000 at start-up), with a 50 amp outlet as a bonus. No buyer reviews yet, so the Westinghouse 28,000W Gas has to win you over on paper. Honestly, the catch: an open frame is loud at full speed, so think about where it sits and who sleeps nearby. We'd pick it if you want most of the house running, not just the fridge; otherwise, put it next to the WEN DF1100X 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. Keep stabilised cans ready, never refuel it hot. The 15 hours on the listing are at a light load; plan a refill at night.

Between storms

Run it every month or so for 20 minutes and keep the battery charged. Add stabiliser or run the carburetor dry before storage. Our maintenance schedule has the full list.

Upkeep

First oil change after the break-in hours in the manual, 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 28,000W Gas goes in your cart, check your hookup: 20,000 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

20,000 running watts and 28,000 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 (the CO sensor is a backup, not a permission). Pick the spot now, before the storm. Our CO safety and placement guide has the details.

Fuel and storage

Gasoline goes stale in a few months: stabiliser, a dry place for the cans, and a run every month or so keep it ready. Our fuel storage guide and maintenance schedule cover both.

How it compares

Pick the WEN DF1100X if propane as a second fuel matters more to you; on our rating, the Westinghouse 28,000W Gas comes out ahead.

Frequently asked questions

Is the Westinghouse 28,000W Gas any good?

We rate it 7.7/10 (very good). The rating comes from its documented listing alone, as no customer-review record is captured yet.

How many watts does the Westinghouse 28,000W Gas deliver?

The listing or manual states 20,000 W running and 28,000 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 28,000W Gas run on?

The listing names gasoline. Run it outdoors only, away from doors, windows and vents.

What do you get with the Westinghouse 28,000W Gas?

Its listing states 20,000 running watts (28,000 at start-up), a 50 amp outlet for an inlet box or an RV, a built-in CO sensor, remote start from a key fob and up to 15 hours on a 17-gallon tank at 25 % load. 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 28,000W Gas?

Your load list: 20,000 running watts and 28,000 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 (the CO sensor is a backup, not a permission). Pick the spot now, before the storm. Our CO safety and placement guide has the details. Fuel and storage: gasoline goes stale in a few months: stabiliser, a dry place for the cans, and a run every month or so keep it ready. Our fuel storage guide and maintenance schedule cover both.

Where can I buy the Westinghouse 28,000W Gas?
