1. Westinghouse WGen9500 Generator

the best 10000 watt generator

The Westinghouse WGen9500 is one of the best 10,000-watt generators. It provides 12500 starting watts and 9500 running watts, rendering enough power output for multiple appliances. The run time can vary from 9 to 17 hours, depending on how much continuous operation and power you get from it.

Protected by a heavy-duty frame, the 457cc OHV engine is easy to use and maintain. It has a remote start key fob and electric start. This allows you to power this generator from a distance. There’s also an emergency recoil starter if the previous two don’t work.

The control panel has multiple power outlets, including two USB ports, two GFCI household-style outlets, one transfer switch ready 120/240V twist-lock outlet that is 30-amp, and another that is 50-amp. This portable generator gives you convenient accessories such as an oil funnel and bottle, a battery, and a charger.

If the size is important to you because of limited space, you should be aware that this is a heavy-duty generator with 220 pounds. This means you’ll need a bit more room for it, and consider putting it at least 20ft away from your home for less noise.

Pros

  • The operating noise level is 74 decibels, which is not as loud as other generators in this range.
  • With a 6.6-gallon fuel tank capacity, you get 12 hours of run time at half load, which is more than enough for essential appliances or on the job site.
  • It comes with multiple outlets for all your needs, with added safety in the shape of rubber covers. It’s RV, transfer switch ready, which allows quick and easy setup.
  • The remote start feature is convenient for quick or emergency starting.
  • LED screen to display the frequency, voltage, and lifetime run hours.

Cons

  • Although you get solid polyurethane wheels in the wheel kit, they could be of better quality considering the size of the unit.
  • It comes with a helpful user manual, but arm yourself with patience if you need additional support.

2. DuroMax XP12000EH Dual Fuel

testing the wheel kit

The next one we determined should be in our top ten selection is the DuroMax XP12000EH dual fuel unit. It has a slightly lower peak power of 12000 watts compared to the Westinghouse. But with a running power of 9500 watts, you can rely on it for heavy residential use during a power outage.

Whether you use it for home appliances, construction equipment, or as a backup power source in emergencies, the 457cc OHV engine will deliver. This powerful generator can handle heavy demands, all while being easy to use and maintain.

It runs up to 9 hours on gasoline and 7 hours on propane with a 50% load. The sound level is similar to the previous generator, at 74 dB. So if you want a smooth and quiet operation, you can set up the generator a bit further from your home.

This dual fuel unit comes with multiple outlets that would support various uses. It includes two 120V GFCI household-style outlets, one 120/240V 50-amp outlet, one 120V 30-amp twist-lock outlet, and another 120/240V twist-lock outlet. As for the accessories, you get an oil funnel, a set of tools, DC cables, and a spark plug wrench. It’s also EPA certified and CARB-compliant, making it safe to use in California and all 50 states.

Pros

  • Powering high voltage appliances is a specialty of this unit due to the MX2 power boost technology.
  • The dual-fuel capability makes it versatile and gives you more options.
  • User friendly with an electric start system and low oil shutdown mechanism.
  • If being cost-effective is essential to you, then this is a good option.

Cons

  • The wheel kit that comes with this unit is insufficient and cannot hold the 224 pounds they are supposed to.
  • You’ll be able to set the unit up and run it in no time, but we recommend going online and looking for the latest user manual. The manual that comes with the unit is a bit outdated, so you may get confused.

3. WEN DF1100T 11000-Watt Generator

generator with a propane tank

Let’s continue with the 10000-watt portable generator by Wen products. This dual fuel generator works with either gasoline or liquid propane gas. If you use liquid propane, you can get 9500 starting watts and 7500 running watts. You also get a 47-inch propane fuel hose for quick setup. But if you use gasoline, you get more power output of 11000 surge watts and 8300 watts running power.

The four-stroke OHV engine is powered by an electric start. With a 6.6-gallon fuel tank capacity, the generator can run up to 8.5 hours on half load, which means it’s fuel-efficient and better for your wallet. This dual-fuel generator gives you flexibility, and we find that having choices is always better than having to stick to one fuel type. 

As for the control panel, it’s relatively easy to use, even for beginners. As for power outlets, you have various options here as well. It has four household outlets, one 120V 30A twist-lock outlet, one 120/240V 50A outlet, and a 12V DC adapter plug. In any case, you get a comprehensive owner’s manual which you can and should use while setting up your generator. Finally, it is EPA certified and also CARB-approved.

  • It has handles that can be folded away and 9.5-inch heavy-duty wheels, which are rugged, easy to set up, and dissembled for more accessible transportation or storage.

Cons

  • The included battery is not the best. It may need to be jump-started in order to use. Although the manufacturer claims the battery comes fully charged, that may not be the case.
  • This portable generator requires you to change the oil every 25 hours. This may not be ideal for extended use in camping sites or remote areas.

4. DuroStar DS10000E 10000-Watt Generator

10000 watt for home back up

For our next pick, we choose the DuroStar 10000 watt portable generator. It is less heavy-duty with “just” 129 pounds. But with 10000 watts peak power and 8000 watts running power, it absolutely earns a place on our list. 

It features a powerful air-cooled engine and runs over 10 hours with a fuel tank capacity of 8.2 gallons at 50% load. It also has an idle control feature that allows for saving fuel, money, and ease of prolonged use. Together with low oil warning light, you get a cost-effective unit.

Whether you use it during power outages or you have another good reason. A 10000-watt generator has enough power to run almost anything you need in your house. You can rely on it to run multiple appliances, multiple tools, and various things in your RV.
But can you rely on it to run your whole house? In general, yes. The 10000-watt generators range has enough power and capacity to run an array of devices simultaneously. In an emergency situation, you will be able to power various appliances such as your fridge, freezer, smaller appliances, AC, and of course, the lights.

Blender: 300-1000
AC: 1500-3500
TV: 50-100

This is especially important for those that may require more power, such as a home air conditioner. If your power requirements are lower, then you also check the 7500-watt generators category.

How Many Amps Is A 10000-Watt Generator?

A straightforward formula for calculating amps is the following: Watts/Volts= Amps. This means that a 10000-watt generator working at 240V will produce 42 Amps.
