How to choose a good 10000-watt generator? (Buying guide)

best 10000 watt generator

Maneuverability & Portability

As most 10kW generators are very heavy in general – within 150 – 250 pounds, some might be even 400 pounds (like the HONDA EB10000), you can’t just lift it up and carry around.

That’s why we highly recommend choosing ones that are built with wheels. They will allow you to push or pull the generator here and there effortlessly no matter you’re working in a group or alone.

Pay attention to the wheels’ construction!

It’s best to go for the solid, non-flat wheels that are durable enough to bear such hefty load and on the other hand, can roll smoothly on different terrains with no puncture or inflating.

Choose the one with two addition drop-down handles if possible. They will help two people share the load when they want to move the machine somewhere.

Runtime & Fuel Efficiency 

We guess nobody like to run in and out of the house just to refill their generator’s fuel tank all the time.

If you just want to turn it on and let it run for a certain amount of time, then consider carefully its runtime. This feature is influenced majorly by the machine’s fuel efficiency.

As a basic rule of thumb, the more power drawn from a generator, the more fuel burnt.

To calculate how fuel efficiency of its engine, pay attention to the amount of time it can run at a certain percentage of the load.

For example, the generator A can run in 8 hours at 25% load of an 8-gal fuel tank. At the same percentage of load and fuel tank size, generator B can run in 10 hours so B is more fuel efficiency.

As these features are usually shown on the product’s spec sheet, you can look into that and make a comparison on your own.

Safety features

Auto shutoff is the highly-recommended safety feature that any generator should have.

If your generator runs out of oil, it will automatically shut down to avoid wears and short circuit fast. It also helps to prevent overload sensors when you plug in too many appliances at a time.

For those who don’t know, an overload sensor might lead to serious damage on the generator or in the worst case, is fire.

Which brand of generators is the best?

best generator brands


Westinghouse nails up with over 130 years’ expertise in this field. And that’s also a precious opportunity to let them learn and continuously improve the human-focused design as well as harness the ground-breaking technology.


A bit younger, we have WEN – founded in 1951 by Nick Anton. It has a separate research and development team to gain insights about customers’ needs when developing a specific product line.

An impressive mark is by 2001, they had sold over 50 million consumer units over the world.


Champion was founded in 2003 with the aim to provide durable and dependent generators at the most cost-efficient price range. Up to now, with 2.5 million generators sold throughout North America, it is no doubt the market leader in this industry.


Established in the same year as Champion but DuroMax focuses more on dual-fuel generator lines. What we love the most in this brand is, aside from the enhancement of products’ durability, reliability, and quality, it also improves customer service.

All Power America

Founded in 2005, All Power America has currently been a global manufacturer and also the distributor of outdoor power generation equipment.

Though their products are produced in China, they have passed many separate international regulations, such as CSA, UL, and CARB.


This Japanese company is one of the most popular brands worldwide that can’t be beaten. If there’s only one sure thing on Earth, Honda is the pioneer of technology and meticulousness in this industry.


Compared to the previous big names, Pulsar is like a newcomer in this industry and yet, it is one of the fastest-growing brands with an emphasis on innovation. Besides, the low price range is another forte that helps Pulsar beat against other competitors.


Through years of great technical depth and design experience, A-iPower has gained a good reputation, being one of the most reliable generator brands in America.

Can a 10000-watt generator power a house?

We actually can’t tell you whether a 10000-watt generator can power a house or not as it depends on how many appliances and which appliances that you want it to operate.

In general, a generator which supplies 10kW can hold up well basic essentials in addition to electric hot water heaters, well pumps, and larger AC. There might be some power leftover which is great for kids to busy with a desktop computer or video game.

Can I run my generator in the rain?

It’s typically unsafe to run a generator in the rain but yes, you can. There are some safety solutions to allow doing so:

  • Protect your generator from the rain and wind by using a special weatherproof canopy
  • Cover it with a proper steel enclosure
  • You can make a DIY generator cover to save money

Is it cheaper to run a generator on propane or gas?

Speaking of the operation cost, running a generator on gas is more economical and it’s also more energy-efficient.

However, propane strikes back with cleaner-burning so the lifetime of your generator is lengthened more than using gas. So in the long term, we would say propane is a more cost-efficient option.

How long will a generator run on a 20 lb propane tank?

In general, a 20-pound propane tank can keep a generator run for about 18 to 20 hours at 25% load.

What size generator do I need to run power tools?

To run power tools, it’s good to opt for a 5000-watt generator or larger. The generator size is dependent on how many power tools that you want to run.


At the end of the day, the best 10000-watt generators should be the one that can offer enough power while being quality.

To find out which is the right for you, measuring the workload that you need it for is an essential step. Don’t just blindly focus on the price, the design, or your budget, but rather on what it can bring up for you.

Now, it’s your turn. Good luck!
