Best 10000 Running Watt Generator

Whether you want to power a big job site or a large home, a generator running on at least 10,000 watts is a must. In broad lines, the market is full of power generators, but surprisingly, there are little choices when it comes to picking the best 10000 running watt generator.

Here's a list of Best 10000 Running Watt Generator

Luckily, most of the choices available are valid ones, that can easily satisfy regarding value for the money.

I know the choice is never easy, and this guide is meant to help you pick the right 10,000 running watts or above power generator for you. Here are a few other things to consider before seeing the models.

How to Choose a Power Generator

1. Assess Your Power Needs

The first step in choosing a power generator is assessing your power needs. An average American home needs around 5,000 continuous watts to keep most appliances functioning. This number can increase considerably if you have many appliances.

For instance, if you live in a big house and want to run the A/C system, fridge, TV, and perhaps the wine cellar all at once, your real needs might go well beyond that number.

You could also need more than 5,000 watts of continuous power if you want to power up a job site. Workers using multiple tools at the same time can easily overload a system, so you must make sure your generator lives up to the expectations.

Besides continuous power, you must also consider surge power, which is a boost of current required by many appliances when their motor starts. To make sure your backup system can withstand all demands, I recommend picking a power generator with at least 10,000 running watts and 12,000 surge watts.

2. Consider Mobility

Powerful generators are typically cumbersome machines weighing over 100 pounds. Most of them come with mobility kits consisting of wheels and handles, but this doesn’t mean they are exactly portable.

If mobility is important to you, it is recommended to invest in a well-balanced generator which is easier to transport despite its heft.

You must also check if the handles are foldable. This feature is handy if you want to place the generator in a small enclosed area, giving you more space to move around the machine if needed.

3. Consider Versatility

Now that you’ve assessed two of the most important feature, also check whether the generator serves its purpose. For domestic purposes, your machine might need more 120V AC receptacles. A job site could benefit from at least two 240V AC outlets.

If you’ve chosen a mobile unit and planned to use it on a campsite, also check the possibility to power your RV. Not all generators have a dedicated RV outlet, while others not only have an outlet but even have 12V DC receptacles for batteries.

4. Power Generator Build

The generators producing at least 10,000 running watts are typically expensive, so it makes sense checking the unit’s durability and resistance.

Steel is the preferred material for the frame, and perhaps your best choice if you want to invest in a machine capable of withstanding the harshest conditions. However, remember that steel is often affected by rust, so invest in a unit that has the frame coated with epoxy powders.

Also, check the handle and the wheels. I already mentioned the importance of a folding handle, but make sure it’s sturdy. Pneumatic all-terrain wheels also make a difference in how easily you’ll be able to transport the machine.

5. Ease of Use 

Last but not least, check how easy it is to control the machine. Even if you’re used to operating such a machine, it is important to invest in one that comes with an intuitive control panel. If you chose a dual fuel generator, check how easy it is to switch from one fuel to another, and whether you have to stop the machine to make the transition.

Gas-powered generators are typically equipped with an electric start which makes it easier to power up the machine in cold weather, but that’s not always the case.

If this is important for you, make sure the model you like has an electric start indeed. Also, if there is any particular feature you’re looking for in a generator, check if the model you like has it before investing your money.
