Traditional Generators

Traditional generators are the old models. They use a mechanical alternator to generate AC power from fuel. Without any built-in inverter, the output electric flow fluctuates highly. They are also very loud. But after all, traditional generators are the cheapest and the most powerful for the price.

If you just intend to use the generator for occasionally home power outages, a traditional generator is okay. But, remember not to charge your smartphone with it.

Hybrid Generators

They are called hybrid generators, so you might expect that they are in the middle of the traditional and the inverter, not so good and not so bad.

But for me, this type is the best one. Its output is not as clean as the inverter and not as powerful as the traditional, but it combines both perfectly – clean enough for sensitive electronics and powerful enough for all kinds of appliances.

Champion 4000-Watt – Best overall

How to choose the best generator for home power outage (buying guide)

You need to pay attention to two specs:

  • Output capacity: You’ll need to do some calculation to know the total watts your appliances use. And choose a generator has running watts above that a bit, to ensure that it can power all your appliances properly when power outages.
  • Max runtime: A short power-outage may last for 30 minutes. A medium power-outage may last for hours. And the worst, it may last for days when floods or storms happen.

So, the more runtime of the generator, the more convenient for you – choose one with more than 9 hours of consecutive runtime and you could sleep well all night.

Other things you might want to take into account are:

  • Cleanness and stableness of output power: To power and charge sensitive electronics.
  • Noise level: If your place is small and you have to put the generator near your relaxing place, the noise level is really important. But if you can put it far away, outdoors, being a little loud is not a matter.

Who makes the best generator for home power outage?

Many needed to be taken into account when choosing the best generator brands for home power outages. I’ll pick three of them, balancing quality factors and price factors.

Westinghouse Electric Corporation

Westinghouse is a 150-year company in the engine and power industry. Up to now, they have factories across all the U.S and have become one of the best-trusted brands that make generators.

Westinghouse generators always come with a great warranty and support program. They are also one of the quickest brands that integrated new technologies into their products, in fact, they are the owner of nearly 30,000 patents.

Champion Power Equipment

When it comes to customer service, I rate Champion equal Westinghouse – both are the best. Champion manufacture all kinds of generators for all kinds of purpose, from for RVs to for home power outages and industrial purposes.

They now have sold more than 2.5 million units in North America and received a lot of good reviews.

DuroMax Power Equipment

DuroMax is a young player in the industry. They were founded in 2003, headquartered in Ontario, California, and specialized in making dual-fuel portable generators. They quickly became one of the leaders in the niche due to their ability to get customers’ insights.

If you want a dual-fuel generator for home power outages, you got to have a look at DuroMax models.


What will a 5500 watt generator power?

A typical TV or laptop uses only about 60 watts. A typical microwave oven uses about 900 watts. A 16-cubic-foot refrigerator consumes about 750 watts.

And in most American households, air conditioners consume averagely about 1,000 watts. So, with a 5500-watt generator, you can power 2 TVs, 2 laptops, 2 ovens, 2 refrigerators, and 2 conditioners at the same time!

Why are inverter generators so expensive?

An inverter generator has a built-in inverter to convert the initial electric flow to a higher-frequent, cleaner and more stable output. They have higher fuel efficiency and lower noise while operating than a traditional generator.

So, it is reasonable that an inverter generator will be more expensive than a traditional generator.

Are inverter generators better?

Inverter generators produce the cleanest and most stable output power. They are also the quietest while operating. But they are the most expensive. For me, they are the best, but not always fit anybody.

Can I plug a generator into my house?

It is illegal to connect a generator directly into your house, because the act may harm technicians who are working on the power network. You must install a Dual Power Automatic transfer switch first and then connect the generator into your house outlet.

Can you run a generator overnight?

It depends on your generator max runtime. If you want to run a generator overnight, you have to choose one that has the max runtime more than 9 hours (from 10 PM to 7 AM).

Is it cheaper to run a generator for electricity?

Commercial electricity is always a lot cheaper. So, only use a generator for electricity when needed, such as power outages or camping trips.


I personally like hybrid generators for my home when power outages, especially Champion 4000-Watt. However, it is just my choice, there is no best one, just the one that fits your needs best.
