About Conventional Generators

An ideal conventional generator is one that produces the right amount of power. This is measured in watts. When you’re looking to purchase a generator, you need to find one with the right wattage to power all of your critical household appliances. For example, if the power goes out, you’ll want to keep your refrigerator, some of your lights, and of course, your heating or cooling systems running. A generator that produces 3,300 watts of power will do the job nicely. This machine, the DuroStar DS4000S does just that. A conventional generator is less expensive than the inverter variety. This means that you’ll be able to find one within your budget, even if it has fewer features.

DuroStar DS4000S

Coming in at 94 pounds, minus the weight of the required oil and fuel, this generator is designed to be portable. It measures approximately 17 inches high, 23 inches deep, and 18 inches wide. Despite its small size, it’s able to produce 4,000 watts of starting power and 3,300 watts of running power – more than enough to sustain a household during a power outage without causing major problems. This machine is a little on the louder side, as it measures 69 decibels, the equivalent of standing near a busy, multi-lane intersection. With that said, it is still quieter than other models. The generator has a four-stroke motor that is self-cooled, meaning that some of those decibels come from the cooling system. You won’t have to worry about it overheating at all. The built-in muffler does what it can to dampen any general engine noise. Also, the wheel kit, which would make the generator easier to transport, is optional but is very easy to install when needed. Some users have found that its lightweight and small size make the wheel kit unnecessary. It all depends on your preferences.


The main features of the DuroStar DS4000S are related to safety. It comes with a built-in low oil shutoff, which will prevent the engine from running without necessary lubrication. Other safety features include a circuit breaker, a voltmeter, and an oil level warning light. The main panel comes equipped with two 120 volts 20 amp outlets and one 120 volts 30 amp outlet. This means that it’s capable of running most standard household appliances with ease, as long as you don’t overload the system. These outlets are set into the main panel, which protects them from environmental damage.

This generator comes with a black steel frame that has sound dampeners on the bottom, preventing it from vibrating loudly on the ground. Although you should never run a fuel-powered generator in your house (or even too close to your house) if you had to place it on an outdoor patio, those sound dampeners will definitely come in handy.

As far as environmental damage is concerned, you really don’t need to worry about it – this generator is EPA approved, as well as CSA listed. This means that its exhaust output has been monitored and it is in no danger of adding to the harmful amount of carbon monoxide in the air. The fuel tank holds four gallons, and at full capacity, it will burn through about one gallon an hour. While this doesn’t seem like much, when you consider that the length of most power outages is less than that, you should be in good shape. It will cover those bases nicely.

The motor is started with a pull-cord system that works simply and easily. You won’t have to worry about pushing and pulling a number of levers when you’re in a hurry to hook up some of your appliances to it.

There are several pros and cons to the DuroStar D4000S. They are:


  • This generator is very affordable and is extremely reliable.
  • The lightweight size and shape make it easy to carry around.
  • It has top of the line safety features.
  • It’s designed to reduce engine noise levels as much as possible.


  • The wheel kit is optional, yet necessary if you want the generator to be portable without throwing out your back.
  • It has a manual pull starter, not a button-push system.

Our Recommendation

Overall, the DuroStar DS4000S is a basic model that fits most budgets. If you need a simple to use and set up a generator that will work well in case of a power outage, then this is the best one for the job. While it is a little noisier than most other units, it really gets the job done.
