10,000-Watt Generator Buying Considerations

Not everyone requires the same features in a generator. That’s why it’s crucial to choose one with specifications that meet your needs. Below we’ve compiled a list of our most important considerations when buying a 10000 watt generator.

Price

Not all generators are of the same quality or have the same capabilities. As a result, you will see a wide price range across available units. Bargain 10000 watt generators are nowhere near as efficient, quiet, or lightweight as the more expensive models, nor do they have the same long-term warranties.

Fuel Type And Availability

Generators typically run on either gasoline or propane. Dual-fuel units allow you to choose between the two. It’s best to go with the fuel type that’s most readily available in your area.

Gasoline provides higher output than propane but needs to cool down before refueling. You can switch propane tanks as soon as they run low, and it’s easy to store numerous backup tanks. Proper propane storage is necessary, however, to prevent the risk of an explosion.

Noise Level

There’s no such thing as a silent—or even quiet—high-wattage generator. Many on our list do feature a lower operational decibel rating. Most people find noises between 70 and 74 dB tolerable. Anything higher can affect your quality of life or hearing. Smaller generators  generally run quietly if that's important to you.

Power Outlets

The best generator for you will have an adequate number of outlets available on its control panel to meet your electric needs. Be sure to check both the voltage and amperage of the unit. Some generators have the right number of outlets but are not equipped to power larger household appliances.

Warranty

A generator is an investment that you want to last for a long time. It’s crucial to purchase a unit with a comprehensive warranty. Check with the seller to be certain you understand what the warranty covers. Ideally, your unit has coverage for at least two years.

FAQs

What Can You Run On A 10000 Watt Generator?

A 10000 watt generator will power most critical household appliances. Don’t forget to check whether the individual outlets can handle the amp load of the item you plug into it. Devices with higher power needs sometimes pull too much current for the generator, despite falling comfortably under the wattage limit. Check the user manual for the specific power outputs of the outlets.

When Is A 10000 Watt Generator Needed?

In the past, one would only have seen 10,000-watt generators on construction sites. With extreme weather patterns and frequent power outages, they have become ideal for supporting the power needs of single-family homes. A 10,000-watt generator can handle your refrigerator, fans, and lights until power returns.

How Noisy Is A 10000 Watt Generator?

A generator makes the most noise when you start it. After you flip the switch, the sound reduces to a more constant rumble.

In terms of noise levels, most generators are comparable to an OHV. Quiet 10,000-watt generators fall into the 70-75 dB range. Louder units and ATVs are closer to 100 dB. More info on noise levels available here.

How Much Fuel Does A 10000 Watt Generator Use?

The amount of gas a 10000 watt generator uses depends on the type of generator, the size of the tank, and its runtime.

A conventional portable generator requires 18 to 20 gallons of gasoline to run for 24 hours. An inverter generator only needs 8 to 10 gallons of gasoline for the same amount of time.

Mechanical issues, including low oil, can decrease your generator’s efficiency, resulting in the need to refill the tank more often.

Summing Up

All 10000 watt generators provide portable power for single family homes, worksites, or large RVs. The latest models come with a wide variety of features that get the job done while offering ease of use to the consumer.

If you choose any of the above generators, you’ll likely find yourself pleased with the results.
