PRODUCT REVIEW

Durostar DS4000S Portable Generator, Yellow/Black

We have split our review of the DuroStar DS4000S into useful specification sections.

This will help you to find the information you require about this generator more easily. 

Design

The design of the DS4000S is excellent. It is relatively compact and its overall dimensions are 24 x 17 x 17 inches.

As you can see, it is not overly large. However, this generator does weigh 94 pounds in total. Being quite a substantial weight is not the easiest to transport, and can be a little cumbersome.

In addition to this, as it is not overly large, it is still fairly easy to store when not in use. The generator is mostly black, with a yellow top.

It has an all-metal construction, which makes this generator particularly durable.

This generator has been approved to be used in all 50 states. All of the windings are 100% copper.

Cost and Warranty

The overall cost of the DuroStar is fairly reasonable. Given that it is a popular choice, and is created by a company that can be relied upon, it is certainly worth considering.

When you purchase this generator, you are given a 3-year limited warranty. This is great because it will give you peace of mind should anything go wrong with your generator. 

Engine Specifications

Let’s talk about the engine itself. It is a 4 stroke engine and its displacement is 208 cubic meters. It is a particularly powerful engine which is a DuroStar 7HP 208cc. 

The engine has an automatic shut off when there is low oil. The low oil sensor is a great feature as it will notify you of this quickly so the oil can be replaced.

The fuel capacity of the engine is 3.96 gallons which is a good amount. The fuel tank has an easy to read gauge so you can see when the fuel will need to be replaced.

In terms of the overall power, the Durostar has a peak wattage of 4,000 and a running wattage of 3,300. It does not lack in power and you will have no issues with it providing electricity for what you require. 

As it is such a powerful generator, you can carry out multiple jobs with ease without compromising the power outage. This can include multiple power tools and appliances with high voltages. 

It has an air-cooled overhead valve which helps to keep the engine cool and circulates air around the engine to stop it from overheating. In addition to this, it has a recoil start and surge arrest technology. 

The engine starts up in a similar way to other generators. It has a pull start mechanism that is easy to start up. 

What Is Included?

Here is everything that is included with the DuroStar DS4000S:

  • Product manual
  • Oil funnel
  • Toolset
  • Spark plug wrench

As you can see, it comes with everything you will need to maintain the generator, and add oil.

The instruction manual is detailed and will explain everything you need to know about this generator.

It is easy to follow and understand. 

Power Panel

The power panel of the DuroStar is particularly great because it allows you the option of three different power outlets.

Here are the outlets that it includes:

  • 2 x 120V 20A Household outlets
  • 1 x 120/240V 30A Twist lock

As you can see, this generator does not limit you with how it can be used and it provides you with several different power outlets that can be used simultaneously. 

In addition to this, the power panel also contains a voltmeter. This will help you to measure your voltage input.

Run Time

The overall run time of the DuroStar DS4000S is around 8 hours.

This is based on it being run at half load. 

Noise Levels

When you think of a generator, you would typically expect it to be fairly loud. However, the noise level of the DS4000S is 69dB. While it is not the quietest generator on the market, it is not too loud.

Its muffler system keeps its noise levels down. However, when the generator is powering heavy tools or is at its maximum capacity that is when it will be at its loudest.

For everyday use, the noise levels should not bother you too much, however, and this generator is not too loud to use at night or if you are camping for example. 

Optional Wheel Kit

If you do find that the generator is not the easiest to transport, there is the option to add a wheel kit. This would make transportation a lot easier and less cumbersome overall.

The wheel kit includes two tough wheels that can be used on the majority of terrains. The wheels are particularly durable and as they are made out of sturdy materials, they will not pop.

In addition to this, the wheel kit comes with a pull handle to allow you to pull the generator along with ease. This wheel kit is worth investing in as it will make transportation a lot easier. 

It is worth noting that this wheel kit will need to be purchased at an additional cost and does not come included with the generator. It is easy to install and put together.
