Top 5 Best 10000 Watt Generators Reviewed

01 DuroStar DS10000E (Best Overall)

DuroStar DS10000E

Why It Stands Out to Us

Coming with a whopping 10000W of starting and 80000W of running power, the DS10000E from Durostar is an excellent choice.  For starters, it comes with an eye-catching design and sturdy build that you can’t say no to. This model allows you to switch to idle control, which lowers the RPM of the engine and saves fuel when you don’t need a lot of juice.

Being RV-ready, this unit fits into any motorhome like a glove. Durostar included a low-fuel shutoff so that the generator or your devices don’t get damaged. It also comes with all the power outlines you can expect from a top-quality unit. Besides, it won’t fall too heavy on your wallet. If you’re one of those shoppers who never compromise in quality, make no mistake and go for the Durostar DS10000E.

 Our Experience With the DuroStar DS10000E

  • The design and build quality of the unit seemed world-class. The materials felt sturdy enough to last for a long time. Overall, we were satisfied with the appearance.
  • Durostar did a commendable job in putting together the user’s manual. We found every bit of information we needed about the model in the book. It took less than 15 minutes to install and the manual came in massive help during the installation.
  • We were very satisfied with the performance of the recoil start. The generator started on the first attempt and very rarely needed a second pull to start throughout our time with it.
  • Though it didn’t operate quietly, it made less noise than a lot of the 10000W generators we tested. The idle control worked wonders to decrease the noise levels when we didn’t need a lot of juice.
  • For testing the generator to the max, we kept it on for two days at a stretch on a 50% load. We got about 11 hours of runtime on a tank full of gas. When we increased the load to 100%, we got a little over 9 hours of service.
  • In terms of power outlets, the DS10000E had plenty of options. It featured both 120V and 240V panels along with an additional 12V DC charging ports, which seemed enough for any household.
  • Considering how big and heavy it is, the unit was very easy to move from one place to another because of the wheel kit and the handles.
  • We tested the low fuel shut-off a few times and it worked accurately on each occasion.
  • The model performed great when we paired it with an RV. We used the generator to power every electrical appliance we had in the motorhome and it worked with perfection the whole time.

What We Didn’t Like

  • It didn’t have the dual-fuel feature.
  • There was no hour meter in the unit.

What Could Be Improved

  • Durostar could include an LCD/LED display to show information about the runtime and fuel levels.

02 All Power America APGG10000GL

All Power America APGG10000GL

Why It Stands Out to Us

If you’re a budget shopper, you probably know the hassle one has to go through to find the best deal on a budget. The All Power America APGG10000GL is the best solution for those looking for a 10000W generator at a cheap price. This budget beast produces enough juice to power your entire household.

Despite having an unbelievably low price tag, it doesn’t compromise on features like dual fuel or electric start. The unit has an amazing runtime and all the outlets that you’ll need. Overall, it’s fair to say that you’ll get more than what you pay for with the All Power America APGG10000GL.

Our Experience With the All Power America APGG10000GL

  • We loved the open old-school design of the unit. The chassis seemed sturdy enough to protect all of the components. It’s pretty evident that the manufacturers kept it simple to cut a few corners but they seemed to put together a great device.
  • It took very little time to fully assemble the whole thing and the generator was up and running within the first 20 minutes. We were satisfied with both of the starting methods as the engine started pretty much every time we tried either of the methods.
  • Performance on both of the fuel types was up to the mark. Though running it on LPG lowers the peak power to 8500 watts, it still seemed like a great deal.
  • We powered a large number of appliances with this device and at a 100% load, it provided service for 9 hours at a stretch before we had to refuel. With about 40% load, it ran for 14 hours straight before emptying the tank completely.
  • For how easily affordable it is, the number of power outlets was impressive. You will never run short on the outlets even if you max out on the load.
  • Though the APGG10000GL falls into the ‘heavy’ category, pulling it with the handles from one place to another was almost effortless. The wheel kit did perfect work in making the unit portable.

What We Didn’t Like

  • The operational sound was loud.
  • The open construction exposes it to dust and water.

What Could Be Improved

  • All Power America could suppress the operational noise a bit.

DuroMax XP10000EH

Why It Stands Out to Us

Looking for a portable generator with 10000 watts of power can be a drag. If you’re one of those users who have to move their generators from one place to the other regularly, the Duromax XP10000EH is your best bet. Coming with a massive wattage, this generator can power your house or RV even if you maxed out on electrical appliances.

With the dual-fuel feature, it gives you the freedom to switch between gas and propane anytime you want. If you don’t need to run a lot of devices at once, you can just switch to the idle control, which makes less noise while saving a lot of fuel.

You won’t run out of power outlets with the XP10000EH in your backyard as it facilitates plenty of them. Another lucrative fact about this model is that it comes at a low price point compared to its competitors. Considering all the features and functionalities, this model is an absolute win any day of the week.

Our Experience With the DuroMax XP10000EH

  • The generator came with great packaging and we didn’t find any dents or other issues. The design was pretty sleek and the whole thing looked so well put. Duromax used sturdy materials all over the exterior, which gave us the impression that it’s going to be around for years to come.
  • Setting it up was almost too easy. We finished the installation in no time and it was all set to start within just 10 minutes.
  • We tried starting it with both recoil and electric start and both methods worked perfectly. The pull cord was very easy to pull and didn’t take more than one pull to start.
  • The dual-fuel feature worked like a dream. It ran almost similarly on both the fuel options although we have to admit that performance seemed slightly smoother on propane.
  • We loved the fact that we could occupy both the 120V and 240V outlets simultaneously. The number of power outlets seemed enough for any household or motorhome.
  • It took huge loads like they were nothing. We powered a wide range of appliances like an LED TV, several speakers, a ps4, a 40W guitar amp, a 15000 BTU AC, two fans, a coffee machine, cell phone chargers, and several other devices at a stretch for about 20 hours (except for when we were refueling).
  • It got us about 11 hours of service with around 60% load on a full tank. When we cranked up the load to a solid 100, the runtime understandably decreased to 8 hours.
  • The idle control worked wonders in terms of lowering the operating noise. It seemed like the perfect solution for the time when you don’t need a lot of juice.
  • Performance in the RV was solid as well. We took a little road trip with the generator and used it for 2 days at a stretch. There seemed to be no issues regarding its compatibility with our RV.
  • Though it wasn’t the lightest of generators we reviewed, the wheel kit and the handles made it almost effortless to transfer the unit from one place to another.

What We Didn’t Like

  • The operational noise is very loud.
  • The manual seemed to be out of date.

What Could Be Improved

  • If Duromax could find a way to suppress the noise a bit, it would have been a better product overall.
  • The manual could be more precise.

Our Recommendations

  • If propane is your go-to fuel, make sure to start the unit on gas once a month. This will keep your generator in perfect condition for a long time.

04 Pulsar PG10000B16

Pulsar PG10000B16

Why It Stands Out to Us

If you want your motorhome to never fall short on energy, this model is the perfect choice for you. There aren’t a lot of RV-ready generators out there that can compete with the Pulsar PG10000B16. This massive 209-pound device has huge wattage that should be enough for getting you through big outages or riding sessions.

Coming with the dual-fuel feature, it allows you to choose your preferred fuel type. Other lucrative functionalities like the electric start and hour meter make it stand out among most of its competitors. Pulsar has cut a few corners here and there to keep it at an affordable price range. Overall, the Pulsar PG10000B16 is a great generator you can pick without any hesitation.

Our Experience With the Pulsar PG10000B16

  • The unit came in tip-top condition and most importantly, was incredibly well packaged. It had a bulky construction, which seemed to be made out of high-quality materials. The manufacturers did a decent job in building this bad boy.
  • Though the installation process was fairly straightforward, it was still a two-man job because of the massive weight. We could set it up within 15 minutes including the wheel kit and the handle.
  • Both the recoil and electric start worked perfectly on the first try. Apart from a few occasions, we didn’t need a second attempt to start the device throughout our time with it.
  • It operated almost equally on both gas and LPG. You do lose 1000W of power on LPG but considering that it’s way cheaper than gasoline, it’s still a great option to have. The fuel switch needed to be operated manually to change the fuel source.
  • Being a heavy-duty machine, you probably wouldn’t want to move a lot with it. We put it in an RV and used it for three days straight. Surprisingly, it worked better than most RV-ready generators we tested and it’s been our favorite RV generator ever since.
  • We powered a lot of devices with the unit including a 15000 BTU AC, an LED TV, a sound system, a ps4, a water heater, two fans, a few lightbulbs, and some other small gadgets all at once to test the machine at a full load. A full load emptied the tank in 8-9 hours on average. We could squeeze 12 hours of service on a 50% load.
  • The Pulsar PG10000B16 had power outlets for days. We were well covered in terms of outlets and never felt like we needed more.
  • Other components like the hour meter, the handles, and the wheel kit functioned exceptionally well. We also tested the low-fuel shut down a few times and it worked accurately every time.

What We Didn’t Like

  • It was very loud, especially when it was fully loaded.
  • Some users experienced issues starting the unit on propane.

What Could Be Improved

  • The operational noise could be suppressed a little
  • The energy it produced could be a bit cleaner.

Our Recommendations

  • Using a muffler pipe will decrease the operational noise by a huge margin.
  • If you plan to run the generator on propane, make sure to start it on gas once in a while.

05 Firman H08051

Firman H08051

Why It  Stands Out to Us

It’s very rare for a conventional generator to operate silently. The Firman H08051 is one of the only few models that operate quietly without having an inverter. This generator comes with a fierce 8000W of running power that can run a wide range of appliances in your home or RV.

Coming with a hybrid carburetor, the H08051 can run on either gas or LPG. It’s also incredibly fuel-efficient. So, you can expect it to save a few bucks every time you use it. Besides, you’ll get features like electric start and low-fuel shutdown with this powerful device. If the price tag doesn’t concern you, stop looking elsewhere and go for this incredible generator.

Our Experience With the Firman H08051

  • Firman kept the unit as compact as it could get. The design was world-class and the materials used all over the generator seemed very premium.
  • Assembling the unit was child’s play. We could set the whole thing up in less than 20 minutes. The user manual came in great help during the installation.
  • We were very happy in terms of the starting methods. Both the recoil and electric start didn’t need one attempt to work.
  • Though it wasn’t completely silent, the operational noise sounded like that of a hairdryer, which is exceptional for a conventional generator. Firman did an amazing job in suppressing the noise.
  • This model took huge loads like they were nothing. We powered a series of highly demanding appliances and the performance was mind-blowing. We used a 2 ton AC, a 64” LED TV, a sound system, two guitar amps, a ps4, two fans, a water heater, and a few lights to test the power output. Surprisingly, even with all those devices, it wasn’t a full load.
  • On a full load, it emptied the tank in 10 hours and with half as much load, we got about 15 hours of service. This unit is undoubtedly one of the most fuel-efficient generators that we reviewed.
  • Performance on both gas and liquid propane was great. However, the starting and running wattage decreased while on LPG.
  • We found the power panel very user-friendly. It facilitated every power outlet we needed. The fuel selector switch was right beside the power outlets.

What We Didn’t Like

  • Firman didn’t include an hour meter with the unit
  • The weight made it difficult to move from one place to another
  • Relatively expensive

What Could Be Improved

  • An hour meter would make this device even more user-friendly.

Best 10000 Watt Portable Generators: Buying Guide

10000 Watt Portable Generators

1. Power Output

The power output of a generator is usually measured in watts. Every generator features two types of power output;

a) Startup Wattage

b) Running Wattage

Usually, most electrical appliances require 2-3 times the power to start, compared to what they require for running. So, if one of your appliances needs 1000 watts to run, the requirement for startup wattage of that device will be 2000-3000 watts. That’s why, before purchasing a generator, it’s crucial to know the amount of wattage your appliances would need to start and run. Make sure to go for a generator that has the required wattage covered.

2. Fuel Capacity & Runtime

It goes without saying that generators with bigger fuel tanks will run longer than the ones with smaller tanks. Most modern generators, no matter what kind of power they produce, feature tanks that can fuel the engine for 7-8 hours at least on 50% load.

However, always remember that a generator with a large fuel tank will most assuredly be less portable and heavier. Make sure you don’t compromise on the portability just for having a bigger tank.

3. Power Outlets

Determine the kind of power outlets you will need in your generator before you choose a certain model. Usually, smaller generators only have 2 120V AC outlets and around 2-4 USB ports. On the flip side, bigger generators that produce more power feature 240V plugs in addition to multiple 120V outlets and USB ports.

Make sure to check if the outlets are certified by GFCI for protection. Most 10000W generators you’ll find will have sufficient power outlets and GFCI protection. So, it shouldn’t be difficult to find the best 10000W generator in terms of power outlets.

4. Noise Levels

Most generators on the market make a lot of noise during operation. Traditional generators can produce from 48 to 65 dBA of sound from a distance of 50 feet, which can get as high as 95dBA in close proximity.

On average, a normal conversation creates 60dBA of noise, and anything more than 80dBA can be dangerous for your health. If you want to avoid this immense noise, make sure to opt for an inverter generator. Most inverters make 54-58 dBA of noise, which is often less than the sound of two persons talking.

5. Starting System

Three types of starting methods are seen in generators;

a) Recoil start

b) Electric start

c) Remote start

Some generators feature all three of the methods and some feature only one or two. However, the starting system of a generator doesn’t necessarily indicate the quality of the unit. Rather, if you don’t mind pulling a recoil cord for turning your generator on, you can go for a unit that only features recoil start and save a few bucks.

6. Safety Features

Modern generators come with safety features that keep both you and your appliances out of harm’s way. The most common safety features are;

a) Low-fuel shutoff

The low-fuel shutoff simply turns the generator off when the oil falls below a specific level. It saves the engine from damaging itself. Having the low fuel shutoff increases the lifespan of a unit. Most generators on the market come with this feature.

b) CO shutoff

This feature is referred to differently by different manufacturers. Many brands use terms like “CO protect”, “CO shield” or “CO guard” for their own marketing policy. No matter what it’s called, its job is to detect the CO (Carbon Monoxide) level and to turn off the machine immediately when it crosses a specific level.

Carbon Monoxide is a deadly gas that cannot be detected by smell or sight. This feature saves both the unit and anyone near it from the fatal blow of the gas. Check for UL2201/ANSI certifications for assuring that the unit you’re going to buy has CO shutoff.

7. Portability

Adding a pair of wheels to a heavy and high wattage unit doesn’t make it portable. A generator has to be compact and lightweight to be called portable. However, this doesn’t mean that heavy and high wattage units can’t be portable. Any unit that has enough features that make it easier for the user to transfer the device effortlessly from one place to another can be called a portable generator.

As you’ll be looking for 10000W generators, you should know that most of them won’t be compact and lightweight. So, make sure that the unit you’re going for has comfortable handles and wheel kits that are easy to use.

8. Other Important Features

a) Hour Meter: Hour meters show you the runtime of your unit. Apart from that, you can also get confirmation about how fast the fuel tank of your generator empties.

b) Fuel Meter: This meter allows you to keep track of the fuel levels. This feature comes in handy, especially during extended blackouts.

c) Remote Control: Generators can be really loud from close ranges. A remote control simply saves you from going close to the generator every time you need to make a change.

d) Dual Fuel: This is one of the must-have features in any generator. This allows the user to use either gas or propane as fuel. However, most generators with this feature tend to run better on propane. So, if you’re going for a unit with the dual fuel feature, make sure it performs equally on gas and propane.

9. Warranty

Most renowned manufacturers include warranty policies in their generators. The warranty on a generator can range from 1-5 years depending on the brand. In some cases, the warranty can be extended by paying an additional amount of money. Some brands add cashback policies with their products. Keep in mind that budget-oriented units won’t have these lucrative warranty policies. So, with an increase in your budget, you’ll be more likely to get your hands on a generator that has a great warranty policy.

10. Budget

Most 10000W generators will cost you between 900-3000 dollars depending on the features and functionalities they come with. Keep in mind that a 10000W inverter generator will cost more than a conventional unit of the same wattage. So, if you’re short on cash, consider opting for conventional generators.

Types of Fuel for Generators

i) Gas

Gas is the most commonly used fuel for generators. In fact, two in every three generators in the USA run on gasoline. Though it doesn’t burn clean like diesel, there is no competitor to gasoline regarding availability.


Diesel works way more efficiently in generators compared to gas. However, this fuel type can be very difficult to find in certain areas. Diesel-fueled generators are generally heavier and louder than the others.  That’s why diesel is commonly used in industrial generators.

iii) Propane

Being the cheapest of the bunch, propane is also the most efficient fuel used in generators. However, because of the lack of availability, it’s not as popular for fueling generators compared to gasoline and diesel.

Safety Tips

  • Avoid running your generator indoors or in enclosed areas.
  • Make sure to turn off the unit when it starts to rain
  • Ensure that the generator is switched off before refueling.
  • If your generator doesn’t feature the low-fuel shutoff, keep an eye on the fuel levels.
  • Make sure that your generator has the CO shutoff feature.


Q: How can I protect my generator from the rain?

A: For starters, never keep your generator outside without a protective cover or a shelter. If you’re using a cover, make sure that it’s waterproof. Last but not least, always unplug and switch off the unit as soon as the rain starts.

Q: Can I use a 10000W generator to power an RV?

A: A regular-sized RV maxed out with electrical appliances will need a capacity between 5000W-7000W. So, if you’re not going overboard with your devices, a 10000W generator should be more than enough to power your motorhome.

Q: What is the lifespan of a 10000W generator?

A: Most generators with a capacity over 5000W have a lifespan of 10000-30000 hours. This depends heavily on the number of hours you run it each year. If your generator is maintained and serviced regularly, it can last for 10-12 years with ease.
