Buying Guide

There are a few critical components to look for when comparing 10,000-watt generators with one another. Whether you want one of the generators on this list or want to look elsewhere, you will need to be familiar with these features to ensure that you know how to compare generators with one another.

Starting Watts/Running Watts

This feature may be the most important one to look into and compare. The starting watts of generators will determine the appliances you will be able to power up with the generator. This is key when trying to start and run larger appliances on generated power. The higher the starting watt, the larger a motor you can power. Things like refrigerators and air conditioners will take a higher starting wattage to run. If you’re stuck in the desert or you have perishable goods it will be important to have a high enough starting and running wattage to power these.

The running watts are a measure of how much power your generator produces while it is running. This lets you know what appliances your generator can continuously power, and that is usually different from what it can start up. Whereas starting watts are sort of the jumper cables to an appliance’s “battery,” in this metaphor the running watts are the car’s engine power once the battery has been started back up and put into motion. This will also help you determine the number of appliances you can keep running while you wait for the power to come back, so you can prioritize importance.

As a common rule of thumb, the higher your wattage is when it comes to both starting and running power, the more fuel you will need to power your generator. All of these generators have a 10,000-watt or a bit more starting power, but pay attention to the running watts because those will vary from generator to generator. For example, Pulsar G10KBN runs at 8000 watts on gasoline and 7000 watts on propane. Keep in mind how many appliances you will need to power off the generator at any given time.

A good place to start is to add up the number of watts each of your appliances needs to run and find a generator that has at least that many watts.

Pulsar G10KBN -3

Conventional or Inverter

A conventional generator is the type that usually comes to mind. They’ve been around for nearly as long as generators have been necessary. These rely on a motor and alternator and use gas to run. Think of them kind of like a car’s engine, but instead of powering an automobile or lawn mower, they power whatever appliance gets plugged into them.

Their smaller and lighter cousins are the inverter generators. These inverter generators are quieter, and you won’t hear the motor running on them constantly. These got their name because they invert power, changing Direct Currents (DC) into Alternating Current (AC). This means you’re less likely to see power fluctuations.

Conventional generators typically run on one speed. You can’t increase or decrease their power flow. Inverter generators allow you to adjust the amount of power they are drawing by controlling the speed. This lets you keep them running for longer on the same amount of fuel by reducing their power output and powering fewer appliances for a longer period of time.

Inverters are rising in popularity because they are greener and more eco-friendly, they’re more beneficial and flexible in capacity, and they’re typically quieter than most conventional generators. These are also the favorite generator of campers, people looking for portability, and hippies. Conversely, conventional generators are great for large-scale projects that require stable power, like entertainment systems and power tools.

Fuel Options

Some generators come with two fueling options or methods while others will only have one. Larger 10000-watt generators will sometimes have both liquid propane and gasoline, as an example, while many smaller inverter generators will only have one propane or gas tank option.

Having dual fuel options is not a necessity, but it’s a good idea if you never want to accidentally run out of power. If you ever need to switch to another fuel source and an emergency, a generator with dual fuel compatibility will be able to keep running through the crisis.

Fuel Capacity and Efficiency

Fuel capacity is important if you don’t know how long you will be without power. This determines the length of time you can run your generator before it dies and requires more fuel. Remember to plan for the amount of fuel you foresee yourself needing. If you’re using this as an emergency just-in-case system, then be careful with how much fuel you keep on hand and how you store it so you keep your home safe and your supply doesn’t evaporate.

Larger fuel tanks will obviously run for longer periods of time before needing to be refilled, and will also require more fuel. These add some extra weight to your generator, but in the end it’s usually worth doing for the extra run time you get from it. For example, the Firman H08051 has an 8-gallon fuel capacity which keeps it running for around 12 hours.

9 Best 10,000-Watt Generators

The other thing to look at is how efficient your engine is. If you’ve got a huge fuel capacity but fuel-efficiency is terrible, it’s like driving a classic car. It looks cool and sounds great, but at the end of the day, you will not get nearly as far on the same tank capacity as you will with more fuel-efficient Hondas. Having a terrible fuel efficiency may cost you more in the long run than just buying a tank with a smaller fuel capacity but amazing efficiency.

To figure out fuel efficiency, look at the run time of your generator. Most models will let you know how long a generator will run at various power loads. In general, you want at least 9 to 13 hours of fuel at half of its power load. These generators can usually do a lot of work or get you through any power outage without having to refuel, and the 10-hour capacity will see you through the evening without the generator dying while you’re asleep.


A good 10000-watt generator should be able to power at least 4 outlets at a time. If it can’t power at least 4, then skip it and find a better model. You want to make sure that you can plug the essentials directly into the generator.

You could use a power strip to get additional appliances plugged in, but this is not recommended unless you want to power a few cell phones or other extremely low watt appliances because it will draw the same power as the other outlets and have that redistributed across everything plugged into the strip, drastically reducing capacity and efficiency and quickly sucking away power from the generator.

If you’re using the generator to power your RV while camping, then you need to make sure that your generator has some RV ready outlets. It also avisable to see if it has the ability to accept some common foreign outlets just in case. Look for a generator with a 30A RV Twist Lock if you’re using this for RVs and campers.
All of the generators on our list feature multiple outlets and are compatible with twist lock and RV campers. The Wen DF1100T even includes a 12V cigarette style charger.


While this is probably the least important factor, it is not something that should be entirely neglected. If your generator is so loud it makes you go deaf and you can’t hear anything being said, and can’t think, then you may wind up feeling that it would be better not to bother with the power. For this reason, at least half the generators on this list operate at 75 decibels or less, making them suitable for residential areas, like the All Power American APG3590 CN.

If you plan on using your generator outside or in a workshop, then you can probably ignore the noise factor. The outside air will dissipate the vibrations and noises. When it becomes an issue is if you plan to use it indoors regularly. The vibrations and sound will have nowhere else to go so they’ll jut echo inside your building, making it worse and worse because of the resonance. There’s nothing worse than trying to sleep or get work done with that massive amount of noise constantly rattling in your hears.

The quieter generators will all be inverters. They’re much quieter, producing less than 60 dbA of noise, making them suitable for use indoor. That’s not much louder than a conversation or television will naturally generate. The conventional generators are usually significantly louder.


A warranty is nothing to sneeze at or ignore, especially if you are buying a generator for an emergency backup and won’t be using it regularly right away. What is good about having a warranty if it expires before you even use the product one time, right?

The warranty will let you know how good the generator is. If a company doesn’t back the product, or knows it is cheaply made, the warranty will be extremely limited in scope. Consequently, some of the best companies out there will offer very excellent warranties because they know their products are built to withstand the test of time and high capacity needs. A generator with a great warranty and tech support is going to last you much longer than one that is given a 1 year or 90-day limited warranty.

This can also tell you a lot about a company. If their warranty has lot so hurdles then you can pretty much guarantee they won’t be very service focused and will do everything they can to make it a time waste to contact them when something goes wrong. A straightforward warranty and money back guarantee are indicators of a company that will be available and responsive to any of your needs.

For example, the Generac offers best in class customer service. Not only do their products come with one of the best warranties on the market, but they also offer 24/7/365 customer service for all of their generators. They’re located in Wisconsin, so you never have to worry about finding service that understands your needs.

All Power America APGG10000


The last thing to consider is how portable your generator is or needs to be. The larger capacity generators are much, much heavier than their lighter counterparts, but that doesn’t mean that they aren’t meant to be portable.

Check the size and weight of each generator to determine whether or not it will be easy to move around and lift. Larger generators are going to weigh more and if you plan to move them to a car or use them at campsites, then they are going to be a bad choice compared to lighter and smaller ones.

Nearly all of the generators on this list are built with wheels and handles, and the Firman is the best of them all. It features these necessary features, so you won’t need to lift it or carry itall over the place. You can just push and pull it, which requires significantly less strength and effort.

Final Words

No matter which generator you choose, you should now be able to buy with confidence. You know what to look for when determining which generator to buy and you can calculate how long it will power up your critical appliances.

Make sure to check out the Honda EB10000. It’s the best 10000-watt generator that built to last. It’s quiet and efficient. You’ll be pleased to buy it once and for all, so it’ll never gets you down with its quality.
