5,300 running watts, 6,500 at start-up

That's the running figure the listing states, on gasoline; on propane it drops to 4,800. On paper that covers the fridge, the freezer, the sump pump and the lights; central air and a 240 V well pump together are another story.

Why it made our list

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. The listing puts propane at 4,800 running watts.

L14-30R twist-lock. A locking 30 amp, 240 V outlet that matches a standard inlet box. With a transfer switch or an interlock fitted by an electrician, whole circuits run off the generator instead of a tangle of cords.

Extension cords or a transfer switch?

Extension cords: the cheapest start. The fridge, the freezer and a lamp plug into the 120 V outlets; the furnace, the well pump and the water heater stay dark.

A transfer switch: the listing names an L14-30R twist-lock, 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'd rather store propane tanks than cans of gas
You want it wired to the panel, not to extension cords
Kids or pets in the house make CO safety a must

Skip it if…

You never want to pull a cord: the listing names no electric start
You simply want our top pick: that's the Westinghouse 5,000W Dual Fuel Inverter (9.2/10)
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 6,500W Dual Fuel listing:

5300 Running Watts & 6500 Peak Watts.
Features One 5–20R 120V 20V Household Duplex Receptacle, One RV-Ready TT-30R 30A Receptacle, and One Transfer Switch Ready L14-30R 30A Receptacle.

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 6,500W Dual Fuel listing names:

5,300 running watts, 6,500 peak
Runs on gasoline and propane
4,800 running watts on propane
Outlets named: L14-30R, TT-30R
Sold as transfer-switch ready
CO sensor
4.7 gallon tank
274 cc engine

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

The manual has the last word on fuel, oil and the outlet ratings; read it before the first start.

Price and cost per 1,000 running watts

$579 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each 1,000 running watts works out at about $109.25 (price ÷ stated running watts, our arithmetic). That puts it in the cheaper third of the 18 generators of 4,000 to 8,000 running watts we have a price and a stated running figure for.

The online price is the generator alone: the cord, the inlet box and the electrician who wires the transfer switch or interlock come on top.

The button opens the exact listing (ASIN B099KS71QX), where today's price, stock and seller apply.

A better fit for your load list?

Want to hook it to the gas line? The Champion 8,125W Tri Fuel (7.6/10) runs on gasoline, propane and natural gas.

Rather not pull a cord on a January morning? The Westinghouse 7,500W EFI Dual Fuel (7.6/10) has remote and electric start.

Want a CO shutoff? The WEN DF8000X (7.5/10) names a CO sensor that shuts the engine off.

Our take

The verdict

We like the Westinghouse 6,500W Dual Fuel for 5,300 running and 6,500 peak watts and the choice of gasoline or propane. No buyer has reviewed it yet, so our 7.7/10 comes from the spec sheet alone. Honestly, the catch: no electric start in the listing, while most picks here have one. We'd pick it if you'd rather store propane tanks than cans of gas; otherwise, put it next to the Westinghouse 5,000W Dual Fuel Inverter 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

Pull the cord, 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. 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 6,500W Dual Fuel ships, check the propane rating: it is rated 4,800 running watts on propane against 5,300 on gas, so size your list for the fuel you will actually use.

Before you buy

Your load list

5,300 running watts and 6,500 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

It has an L14-30R outlet, which still needs an inlet box and a transfer switch or interlock installed by an electrician. Our transfer switch guide explains the options.

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 for three days

A 20 lb tank lasts far less than a day at half load on most big units; two or three full tanks make a realistic plan. Our fuel storage guide covers storing them safely.

Frequently asked questions

Is the Westinghouse 6,500W Dual Fuel any good?

We rate it 7.7/10 (very good), #2 of 5 in our RV generators with a 30 amp outlet ranking. The rating comes from its documented listing alone, as no customer-review record is captured yet.

How many watts does the Westinghouse 6,500W Dual Fuel deliver?

The listing or manual states 5,300 W running and 6,500 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 6,500W 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 6,500W Dual Fuel?

Its listing states 5,300 running watts (6,500 at start-up), the choice of gasoline or propane, an L14-30R twist-lock for a transfer switch and a built-in CO sensor. 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 6,500W Dual Fuel?

Your load list: 5,300 running watts and 6,500 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: it has an L14-30R outlet, which still needs an inlet box and a transfer switch or interlock installed by an electrician. Our transfer switch guide explains the options. 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 for three days: a 20 lb tank lasts far less than a day at half load on most big units; two or three full tanks make a realistic plan. Our fuel storage guide covers storing them safely.

Where can I buy the Westinghouse 6,500W Dual 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.

Have you used the Westinghouse 6,500W Dual Fuel yourselves?

No, we haven't used it ourselves. Everything on this page comes from its listing, read line by line and weighed with our published formula, plus our editors' read of how it compares with its rivals.
