10 Best 10000-watt Generators: In-Detail Reviews (Fall 2022)

What can 10,000-watt generators do?

A 10,000-watt generator is powerfully designed to run multiple tasks. The machine can run all essential items such as air conditioners, light circuits, freezer, furnace, refrigerator. And in most cases, you can run the devices concurrently.

Safety advice for using 10,000-watt generators

Undoubtedly, a generator is an invaluable product that can help your life feel normal again during a power outage. However, you should never overlook basic safety measures while operating the equipment.

Carbon monoxide can kill you in less than five minutes. To reduce this risk, some units are designed with built-in sensors to trigger automatic shutoff if the CO builds to toxic levels. Whether you’re operating an older model or you want to buy a new generator, these safety tips are essential:

  1. Avoid Running Your Generator Indoors or In an Enclosed Space

Most generator mishaps, deaths, and injuries involve carbon monoxide poisoning, either indoors or enclosed. Running a generator in a garage or basement is dangerous. Ensure your unit is at least 20 feet away from the house. The exhaust should also be directed away from doors and windows. You may also consider using battery-operated units for added safety.

  1. Avoid Operating In Damp Areas Or In The Rain

There is a myriad of tools that can be used to protect the generator from rainwater. Invest in a reliable generator tent to protect the unit but still offer excellent ventilation. You can find tents in both online and local stores.

3. Always Let the Generator Cool

Before you refuel the generator, allow it to cool by turning it off. Gasoline spilled on a hot engine can ignite. A cooled engine reduces the risks of burns while refueling.


  1. Change the Engine Oil

It’s recommendable to change the engine oil after every 20 hours of usage. If you want to store the equipment for more than 30 days, change the oil too. Alternatively, use an oil stabilizer.

  1. Consider CO Safety Technology

To buy a 10,000-watt generator, consider the unit endowed with the CO alarm feature. Modern generators are equipped with devices that detect toxic levels of CO and automatically turn off the machine.


Generators come in different prices and sizes. But for a 10,000-watt generator, you might consider digging deeper into your pocket. The price ranges from $200 to approximately $1,000. Anything below $200 might not deliver the expected result. But if you want more features, more power, and incredible performance, you might consider a unit worth more than $1,000.

10 Best 10,000-watt Generators - Power Loss is no Longer a Threat (Fall 2022)

Buying the best 10,000-watt generator involves more than just walking into a store and swiping your card. You need to pay attention to several factors. Some of the essential features to consider include:

Fuel type

Like cars, generators are designed to use different kinds of fuels, including propane, gasoline, natural gas, and diesel. Fuel consumption varies based on electrical capacity, fuel type, brand, and weather conditions.

Gasoline generators, such as WEN DF1100T, are designed to be lightweight and compact. They don’t have large and heavy fuel tanks, resulting in shorter run time. Their fuel economy can be as much as 40%. Gasoline is a common energy resource, which is easy to obtain. However, it’s highly flammable and dangerous to accumulate in great volumes.

Diesel isn’t popular for generators but is more effective and efficient compared to gasoline. And it’s safer and inexpensive to run. It’s not as flammable as most fuels. It has decent fuel efficiency and serves various purposes, including permanent power supply for RVs, emergency backup, and construction site power.

On the other hand, propane fuel is the safest fuel type for generators. It burns clean, can be stored for an extended period and seamlessly kept in different cylinder sizes. Propane burns quietly and delivers longer operations hours. This type of fuel minimizes carbon emission, making it eco-friendly.

Generator portability

The beauty of using a portable generator is that you can move it to wherever power supply is needed. Now, 10,000-watt generators are quite heavy, but most come with transportation wheels that make it easy to cart them around. And you can transport them in the car if you wish to use them in a distant location. Remember that not all generators have wheels, so choose carefully, and pick one with large wheels because they roll easier. Ensure that it has a handle that you can use to push or lift the generator.

Power output

The high-power output from 10,000-watt generators makes it possible for you to power most of your home appliances concurrently. Many of these generators have an output of 10,000 starting watts and between 8,000 and 9,000 running watts. With this wattage, you can power all the home essentials, including lights, refrigerator, freezer, microwave, TV, and the sump pump. You can also connect things like water heaters, a large air conditioning unit, and even a well pump.

Fuel tank capacity

A generator with a high fuel tank capacity will run uninterrupted for longer periods of time. If the tank can only hold a small amount of fuel, it means the runtime will be shorter. You’ll also need to refill the tank more frequently than you would if the generator had a bigger fuel tank. An eight-gallon generator tank will run for 10-12 hours at half load, making it possible for you to enjoy uninterrupted power supply for those important tasks you may have. Durostar DS10000E, Pulsar PG10000, DuroMax XP10000EH, All Power America APGG10,000, and Gentron Power Equipment GG10020GU will all give you this.

Noise level

The amount of noise a generator produces depends on the engine size, design of the enclosure, the type of insulation used, the quality of mufflers used, and how efficient the air flow is. Because all these vary from generator to generator, the noise level also varies across different generators. But on average, 10,000-watt generators produce between 70-79 dBA. This would be the noise equivalent of an electric drill, power lawn mower, vacuum cleaner, or freeway traffic.

If you will be using the generator for long periods at a time, choose a unit with a lower noise level just to reduce your exposure to the noise. Note that even between two generators whose noise rating is nearly the same, the actual noise that each emits can be very different.

Running time

Generator runtime depends on the fuel tank capacity and the machine’s fuel efficiency. Most portable generators have a runtime of 10-13 hours at half load. Some can go for 24 hours, and some modern models have a 72-hour runtime, but these are few. This translates to a lifetime runtime of 10,000-20,000 hours at half load, which is the equivalent of 1 or 2 decades if you use the generator occasionally. If you use the generator constantly to the point where you’re running it close to 24 hours a day, its lifetime runtime will be drastically reduced.

As with any mechanical machine, something could go wrong and the generator suddenly stops working. A warranty ensures that the manufacturer or seller can take care of such a problem at no cost to you. Be sure that you check the kind of warranty the manufacturer gives for the generator you want, how long it lasts, and what it covers. Most generators come with a 2- or 3-year warranty. Few are guaranteed for only 1 year, and some are covered for more than 3 years.


Many modern generators come with a carbon-monoxide detector that automatically shuts off the engine if it detects high CO levels in the room. In addition to this, some generator engines produce low amounts of CO. To know whether the generator you’re about to buy meets the standards for CO emission, check whether it has the ANSI/UL2201 certification for CO safety. Some also have an auto-shutoff feature that is activated during an emergency.

You must observe safety precautions when using the generator to minimize risk of electrocution and/or blowing up any plugged-in appliances. Some critical things to observe are:

  • Always operate the generator outside the house
  • Connect the generator properly
  • Avoid overloading it
  • Allow the (turned off) generator to cool before refueling it
  • Never use the generator in wet conditions (like in the rain)
  • Never backfeed your home, meaning don’t ever plug the generator into a wall outlet.


Portable generators come with built-in outlets which you can use to connect extension cords. This applies if you have not connected the generator to your circuit-breaker panel via a transfer switch.

The generator usually has double outlets, with each supplying 120 volts. Some also have a 12-volt outlet where you can plug in 12V appliances. The more outlets the generator has, the more appliances you can connect. Each outlet has a circuit breaker that safeguards the generator from overloads, although in some models, the generator’s main circuit breaker also serves as the circuit breaker for the outlets.

Where possible, choose a generator with ground fault protected outlets (GFCI) as these are designed to protect you from electric shock.

Extra features

An electric start system is easier to turn on than a manual one. Plus, it does come in handy in situations where it’s impossible to start the generator manually, for example, during a storm.

Fuel gauge and oil gauge – These show you how much fuel and oil you have left in the generator, so you’re never caught unawares when either runs out.

Low oil shutoff and indicator – Generators with this feature automatically shut down if the oil level becomes dangerously low. And the indicator will let you know that you’re low on oil so you’re not left wondering what could be the problem.

Display – Some generators have a display for the oil gauge, fuel gauge, and watts consumed versus available watts. The latter helps you figure out what devices to the plugin so you don’t overload the generator.
