10,500 running watts, 13,000 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.

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. 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 DuroMax XP13000HX'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 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
You'd rather store propane tanks than cans of gas
You plan a transfer switch, or you own a 50 amp RV
You trust a long track record: 1,047 buyer reviews

Skip it if…

You need quiet power for a campsite: this is a big open frame
You simply want our top pick: that's the DuroMax XP12000EH (9.3/10)

Outlets, fuel and what's in the box

What the DuroMax XP13000HX listing names:

10,500 running watts, 13,000 peak
Runs on gasoline and propane
Outlets named: 50 amp, GFCI 120 V
Sold as transfer-switch ready
Electric start
CO sensor
500 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

$1,079 Price on Sep 30, 2026 · may have changed

At the price on Sep 30, 2026, each 1,000 running watts works out at about $102.76 (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 B086Z452V9), 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 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

What we'd buy the DuroMax XP13000HX for is 10,500 running watts (13,000 at start-up), with a gas-or-propane fuel switch as a bonus. 1,047 buyers back that up with 4.5/5, about as reassuring as a review record gets. Where it falls short: no word on the propane rating or the runtime. We'd pick it if you want most of the house running, not just the fridge; otherwise, put it next to the DuroMax XP12000EH 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.

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.

What buyers say

Buyers give it 4.5/5, a strong record, right on this ranking's 4.5 average. And with 1,047 reviews behind it, that number is hard to argue with.

The one thing we'd check first

Before the DuroMax XP13000HX ships, check your hookup: 10,500 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

10,500 running watts and 13,000 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 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 DuroMax XP13000HX any good?

We rate it 8.8/10 (very good), #2 of 4 in our dual fuel generators for home backup ranking. It is based on 1,047 buyer reviews averaging 4.5/5 and the specifications stated in the listing.

How many watts does the DuroMax XP13000HX deliver?

The listing or manual states 10,500 W running and 13,000 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 DuroMax XP13000HX 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 DuroMax XP13000HX?

Its listing states 10,500 running watts (13,000 at start-up), the choice of gasoline or propane, a 50 amp outlet for an inlet box or an RV, a built-in CO sensor and push-button electric start. 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 DuroMax XP13000HX?

Your load list: 10,500 running watts and 13,000 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.

Check the propane rating in the manual if propane is your plan. Our fuel storage guide covers storage.
