Can Portable Generator Run Central Air Conditioner? (Yes!)

Portable generators are indeed a good solution to run your Central Air Conditioner in an emergency like during a blackout. Blackout is common during the hurricane and ice storm season in many regions. 

However, most of us love to use a portable generator rather than a permanent generator. The portable generator is comparatively less expensive than the stationary generator. Moreover, you can use a portable generator for different purposes. 

Most people believe that a portable generator is only for small appliances. The belief is partially true. Actually, it depends on the power of the generator. 

In this article, I have elaborately discussed the portable generator and the central AC. Keep reading. 

Can A Portable Generator Run Central Air Conditioner

Can You Run Your Central Air With The Portable Generator? 

Yes, you can run your central air with a portable generator. But you need at least 10% more generator wattage than your central air wattage. You will get different sizes of portable generators like up to 15KW portable generators in the market. You can run almost all types of central AC with a portable generator.  

Let me clear, please. Say you have a central air conditioner that comes with 6000 watts starting watt. So, you need a portable generator that comes with at least 6500 watts. Yes, your central air will not consume all the power while running. You can run your other appliances then.   

How Many Watts Does A Central Air Conditioner Use?

A central air conditioner uses at least 2000-watt power. The range of the central AC is usually 2000 watts to 10000 watts. To run a central air conditioner, you should have a clear idea of the starting and running wattage of your central air.

Actually, it is tough to answer this question accurately. Every appliance comes with a user manual. You will find the starting watt and running watt of your central air conditioner on the manual. Before buying a generator, don’t forget to calculate all the overall watts of all the home appliances. 

Here is a general power estimation for different types of AC
