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

On paper, the Westinghouse 28,000W Tri-Fuel gets the important things right: 20,000 running watts (28,000 at start-up), tri-fuel flexibility (gas, propane or natural gas) and a 50 amp outlet. With a key-fob remote start as well, it suits whole-house backup on three fuels.

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

That's the running figure the listing states, on gasoline. On paper that covers the fridge, the freezer, the sump pump and, through a transfer switch, the furnace or a well pump; the start-up surge of the biggest motor is the number to check.

What it has going for it

What changes on the night the power goes out

Three fuels. Natural gas from the house line means no refuelling at 2 a.m., and it is also the lowest-output fuel of the three. The hookup is a job for a licensed gas fitter, not a hose and a guess.

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 28,000W Tri-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. An inlet box on the outside wall takes that plug, and an electrician wires it to a transfer switch or an interlock. After that, the furnace and the well pump run off the generator as well; the electrician's bill comes on top.

Great for you if…

You want most of the house running, not just the fridge
Your house already has a natural gas line
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 28,000W Tri-Fuel listing:

Gasoline: 28,000 peak watts and 20,000 running watts.
Powered by a heavy-duty 999 cc Westinghouse V-Twin OHV engine featuring a cast-iron sleeve.
Two 120/240V 14-50R 50A outlets, two 120/240V L14-30R 30A outlets, all transfer switch and interlock kit ready.

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 Tri-Fuel listing names:

20,000 running watts, 28,000 peak
Runs on gasoline, propane and natural gas
Outlets named: 50 amp, L14-30R, L5-30R, GFCI 120 V
Sold as transfer-switch ready
Remote and electric start
17.2 gallon tank, up to 15 h
999 cc engine

In the box, per the listing: Engine oil, A wheel kit, A starter battery.

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

$3,899 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each 1,000 running watts works out at about $194.95 (price ÷ stated running watts, our arithmetic). That puts it in the pricier third 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.

The button opens the exact listing (ASIN B0CQN51MQB), where today's price, stock and seller apply.

A better fit for your load list?

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

Our favourite thing about the Westinghouse 28,000W Tri-Fuel is 20,000 running watts (28,000 at start-up), closely followed by tri-fuel flexibility (gas, propane or natural gas). No buyer reviews yet, so the Westinghouse 28,000W Tri-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 28,000W Tri-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 (the listing says a bottle comes in the box) before the first start, then run it for a few minutes outside with a small load. Fit the wheel kit first; it is easier on the ground.

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. 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. 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, 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 Tri-Fuel ships, 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. 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.

How it compares

How the Westinghouse 28,000W Tri-Fuel stacks up against the closest alternative, the Champion 16,875W Tri Fuel.

Criterion	Westinghouse 28,000W Tri-Fuel	Champion 16,875W Tri Fuel
Our rating	7.8/10	7.8/10
Running watts	20,000 W	13,500 W
Peak watts	28,000 W	16,875 W
50 amp outlet	Stated	Not stated
CO sensor	Not stated	Stated

Both score 7.8/10. The Champion 16,875W Tri Fuel adds a CO sensor, while the Westinghouse 28,000W Tri-Fuel brings more running watts (20,000 W) and a higher peak (28,000 W).

Frequently asked questions

Is the Westinghouse 28,000W Tri-Fuel any good?

We rate it 7.8/10 (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 Tri-Fuel 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 Tri-Fuel run on?

The listing names gasoline, propane and natural gas. 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 28,000W Tri-Fuel?

Its listing states 20,000 running watts (28,000 at start-up), gasoline, propane and natural gas on one panel, a 50 amp outlet for an inlet box or an RV, remote start from a key fob and up to 15 hours on a 17.2-gallon tank. 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 Tri-Fuel?

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. 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.

Where can I buy the Westinghouse 28,000W Tri-Fuel?

We link to the exact listing on Amazon, where today's price, stock and seller apply. It is an affiliate link, and it has no effect on the rating.
