9,000 running watts, 11,000 at start-up

That's the running figure the listing states, on gasoline; on propane it drops to 8,100. Add up what has to run at once (fridge, freezer, sump pump, furnace blower) and the Champion 11,000W Dual Fuel Inverter should have room to spare on paper; the motor that starts last, often the well pump, is the one to plan around.

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 8,100 running watts.

Inverter. The engine speeds up and slows down with the load, so it is quieter and thriftier at 3 a.m. when only the fridge and a lamp are on. The clean sine wave is kinder to laptops, TVs and the furnace control board.

Extension cords or a transfer switch?

Extension cords: run a heavy cord from the Champion 11,000W Dual Fuel Inverter'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 doesn't name a 30 or 50 amp twist-lock outlet, so look at the panel on the unit itself before you plan an inlet box around it.

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
  • Laptops, TVs or a furnace board will be plugged in

Skip it if…

  • You plan to feed a 50 amp inlet box: the listing names no 50 amp outlet
  • 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

Outlets, fuel and what's in the box

What the Champion 11,000W Dual Fuel Inverter listing names:

  • 9,000 running watts, 11,000 peak
  • Runs on gasoline and propane
  • 8,100 running watts on propane
  • Outlets named: GFCI 120 V
  • Electric start
  • CO sensor
  • 64 dB, per the listing
  • 459 cc engine

Warranty & support: A 3-year warranty, as stated in the listing.

That is the maker's promise, not ours. Keep the order confirmation, and register the Champion 11,000W Dual Fuel Inverter if the maker asks you to.

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

$2,229.68 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each 1,000 running watts works out at about $247.74 (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.

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 B0DB3GQSCD), where today's price, stock and seller apply. Sizes and variants of the same family often sit at different prices.

A better fit for your load list?

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

Planning an inlet box and a transfer switch? The DuroMax XP12000EH (9.3/10) has a 50 amp outlet.

Well pump or central air on the list? The Champion 16,875W Tri Fuel (7.8/10) is rated 13,500 running watts.

Our take

The verdict

The Champion 11,000W Dual Fuel Inverter earns its place with 9,000 running and 11,000 peak watts and the choice of gasoline or propane. No buyer reviews yet, so this Champion inverter generator has to win you over on paper. The catch with the Champion: no 50 amp outlet in the listing, while most picks here have one. We'd pick it if you want most of the house running, not just the fridge; otherwise, put it next to the Westinghouse 5,000W Dual Fuel Inverter 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

Push the start button, 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 Champion 11,000W Dual Fuel Inverter ships, check the propane rating: it is rated 8,100 running watts on propane against 9,000 on gas, so size your list for the fuel you will actually use.

Before you buy

Your load list

9,000 running watts and 11,000 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

Plan on heavy-duty extension cords to the appliances, or ask an electrician which inlet and switch would match its outlets. Our interlock vs transfer switch guide compares the two routes.

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 Champion 11,000W Dual Fuel Inverter any good?

We rate it 7.8/10 (very good), #2 of 5 in our inverter generator ranking. The rating comes from its documented listing alone, as no customer-review record is captured yet.

How many watts does the Champion 11,000W Dual Fuel Inverter deliver?

The listing or manual states 9,000 W running and 11,000 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 Champion 11,000W Dual Fuel Inverter 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 Champion 11,000W Dual Fuel Inverter?

Its listing states 9,000 running watts (11,000 at start-up), the choice of gasoline or propane, clean inverter power, a built-in CO sensor, push-button electric start and up to 15 hours per 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 Champion 11,000W Dual Fuel Inverter?

Your load list: 9,000 running watts and 11,000 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: plan on heavy-duty extension cords to the appliances, or ask an electrician which inlet and switch would match its outlets. Our interlock vs transfer switch guide compares the two routes. 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 Champion 11,000W Dual Fuel Inverter?
