While a 10,000 watt generator is not on everyone’s list of necessities, you are going to wish you had one when you need it most.
A 10,000 watt portable generator gives you enough power to run large appliances during a power outage, run a wide variety of tools at a job site, power many of your RV accessories, and even help run a food truck. Many 10K generators are also 50 Amp generators. If you need a 50 Amps, make sure and check out this list of 50 amp plug generators.
What makes these generators highly sought after is their ability to power many types of appliances while still being easy to transport.
Most of these generators feature easy-to-use handles and heavy-duty wheels that make it easy for a person of any age to move.
In this post, I am going to look at 7 of the best 10,000-watt generators and compare them against each other to give you a better idea of what to expect from each.
7 Best 10,000 Watt Generators
- DuroMax XP12000EH
- Firman H08051
- Durostar DS10000EH Dual Fuel
- Westinghouse WGen12000 Ultra Duty
- DuroMax XP10000E
- WEN DF1100
- Generac 7676 GP8000E
1. DuroMax XP12000EH Generator
DuroMax XP12000EH generator is a powerful 12,000-watt portable generator that runs gasoline or liquid propane.
This cart model with solid-fill wheels is not only fantastic for keeping your gadgets running at home, but it’s also appropriate as a worksite generator owing to its heavy-duty build.
This generator’s lengthy run duration looks to be the best alternative for homes that often endure more extended power outages, such as during harsh weather.
Because this hybrid generator can also operate on propane, I thought it has lower operating expenses than a traditional portable generator that runs only on gasoline.
There’s no disputing that this isn’t a quiet generator, but with an 18-horsepower 457cc engine spinning at 3600 RPM, that shouldn’t come as a surprise.
The rated noise level is 74 decibels, I thought it was more than the regular vacuum cleaner but still manageable given the amount of power it produces.
The fact that Duromax is a dual fuel engine, without a doubt, the most significant benefit of this option will definitely help you a lot.
Not only does this work out to be a more cost-effective alternative in terms of operating expenses, but it also allows you to prolong your run time by switching to another fuel – well worth the additional $100 above the simple mono fuel model.

The condition and activity of the WGen12000 may be quickly checked using a control panel, which has a handy meter that shows voltage, frequency, and lifespan hours.
This device has an overload safeguard (circuit breaker) and an automatic low oil shut-off, giving you total peace of mind while using it.
With the number of yearly storms in my location increasing, I lose power more often and for more extended periods each year. With that in mind, my previous generator was no longer enough.
It’s been really dependable, but I’m tired of running (unsafe) extension cables to essential appliances (refrigerator, freezer, etc.), straining to pull-start it, and the dreadful noise it produces.
It was time to upgrade to something a few decades newer, and I have settled on the Westinghouse WGEN12000.

- It saves you money on gas
Cons
- No back-up recoil
- On the heavier side of things (352 lbs)
IMHO: In My Humble Opinion
The Westinghouse WGEN12000 had the perfect mix of features, usefulness, and affordability. Its 3-year home warranty and lifelong technical assistance is excellent. I value the ability to remotely start a generator since it enables me to switch on fuel, set the generator to ‘run,’ activate breakers, and vacate the building before starting the (loud) generator.
5. DuroMax XP10000E
The DuroMax XP10000E includes an air-cooled 16 HP OHV engine that runs at 8000 Watts steady power with a peak output of 10,000 Watts, making it ideal for my work or home.
This portable gas-powered generator comes with both an electric and a recoil start. The EPA-approved design, which includes a suppressed exhaust emission and a spark arrestor, makes it very quiet and meets the criteria of US National Parks.
The DuroMax XP10000E is a monster for work and enjoyment, I thought it will up to 10 hours of operating duration.
It is not affordable, but for the price, it can power my whole home as well as a few air conditioners at the same time, with enough electricity left over to charge some batteries.
I tried everything I could think of to get the voltmeter to go into the red zone, but I couldn’t get it to work.
In reality, the window air conditioner in my living room is rated at 30,000 BTU, which no generator could handle without moaning. When it came to starting up my air conditioner, the DuroMax XP10000E didn’t even bother with sputtering.
There hasn’t been a single twitch in the needle of the voltmeter for two hours. The total power and run time I could get from the DuroMax XP10000E has blown me away.
Specifications
The DuroMax XP10000E features:
- Wattage: 8000 watts

IMHO: In My Humble Opinion
I believe you would be hard pushed to find another low-cost high-powered generator that has all of the settings, key start, and comes with the battery and all of the attachments included.
6. WEN DF1100
With the WEN DF1100, I can generate electricity from two distinct sources. Simply choose my desired fuel type (gasoline or LPG) and start the generator with the keyless electric start.
Propane generates 9,500 surges and 7,500 running watts, but gasoline generates 11,000 surge and 8,300 running watts. Switching between fuels is very simple and safe.
I also noticed that its exterior is more robust than others. I thought it may be one of the best solutions for outside usage, particularly for RVs that need a lot of power.
One of the most excellent features is the electric start, which boosts the 457cc engine instantly when needed. Like the other generators on this list, it’s also a four-stroke OHV engine.
WEN DF1100 does not have the largest gasoline tank, but it is much larger than lesser variants. With a 50 percent load, I thought it can carry up to six gallons of gasoline and provide around eight hours of operating time.
As a bonus, the generator’s handles may be entirely folded down to conserve space.

What Will a 10,000 Watt Generator Run?
A 10,000 watt generator will easily run a refrigerator or freezer. Depending on the size, maybe a central AC unit. 10,000 watt generators will run fans, window air conditioning units, plug-in heaters, some furnaces, and even the kitchen sink! 10,000 watts is enough for most every major household appliances.
Where 10,000 watts starts to run out is when you are running more than one major appliance at a time or large central or whole house air conditioning units. If you’re at a job site or in construction and running 10 Sawzalls at the same time, that would be too much. A typical Sawzall needs about 1,300 running watts, so ten of them would exceed 10,000 watts total.
