DuroStar DS4000S Portable Generator

DuroStar DS4000S Portable Generator
  • 4,000 peak watts
  • 3,300 running watts
  • 2 120V household outlets
  • Engine noise (69 dBA rating)
  • 94.00 lbs weight


Keep your devices powered up longer with the long 8 hour run time. This 8 hour run time is achieved at half power through a mere 4 gallon fuel tank. You don’t have to worry about spending a ton of money on fuel for this generator. With average fuel prices, you can run this generator for less than $2 per hour.

This DuroStar unit is equipped with a super quiet muffler that keeps the noise level to 69dB. This noise level is great for campgrounds as it will not disturb your neighboring campers. Camping generator reviews will solidify the fact that this is an amazing generator for camping.

Not only is this generator great for camping, but it is the best portable generator for home use. With two 120V household outlets and one 120V 30A twist lock outlet, the power panel is ready to handle lights and appliances at home in the event of a power outage. It even has the power to run small household air conditioners as well!

Here are just a few of the things that you can run with this generator:

  • Lights
  • Fans
  • Refrigerator
  • Microwave
  • Small air conditioner
  • Blender
  • Space heater

With a quick glance at the built-in voltmeter, you can easily see the voltage output of the generator. You can easily tell if there are issues with the expected output. A low oil shutoff is also included on this generator, which will automatically shut off the engine in the event the oil level gets too low.

The all metal construction of this beast makes it very sturdy and able to stand up to whatever gets thrown its way. Isolated motor mounts on all four corners make this generator run as smooth as silk. Generators used every day on job sites can sometimes get tossed around and take a beating. This generator can take it!

Safety Features

No need to worry about environmental concerns when using this DuroStar DS4000S. This generator is both CARB & EPAIII compliant, so it is safe to operate in all fifty states. This certainly makes you feel better about running the engine because you typically run these for hours at the time.

This DuroStar is also equipped with Surge Arrest which prevents power surges from the generator. You absolutely want to keep your devices protected from power surges, and you can be confident that they will not be harmed when plugged into the DS4000S.

Outlet Configuration

This generator comes equipped with most of the common outlets needed to plug in almost any kind of household appliance or device:

  • Two 120V 20A household outlets
  • 30 Amp twist lock outlet

In addition to the outlets provided on the power panel, there is also easy access to the 20 amp and main breakers. Easily switch the main breaker on or off to control when power is being delivered through the unit. Safely plug devices into the unit with the main breaker turned off, and then switch things on once everything is plugged in and ready to go.

Safe Generator Operation

While this generator has many built-in safety features, there are still some precautions that must be taken when operating the unit. You should never operate the generator indoors, and you should always make sure that the generator is located at least 20 feet away from your home or RV while it is running. Always follow the operating manual to avoid the risk of shock or electrocution as well.
