Our Review


The DuroStar DS4000S is fitted with a gasoline 7.0-horsepower engine. This produces 3300 running watts and 4,000 peak watts. The power panel features the main controls, including start switch, volt meter, and circuit breaker. It offers two 120-volt, 20-amp, 3-prong outlets (NEMA 5-20R) to supply power to all of your home appliances, plus one 120-volt, 30-amp outlet (NEMA L5-30) for high-powered tools. This generator is ideal for camping, RVs, sporting events, job sites, home back-up and more.


This generator is enclosed in a heavy duty steel frame with four point fully isolated motor mounts for smooth and quiet operation. With a low-oil shutdown system the engine is prevented from any damage caused by low oil.


It is comes with a 4-gallon fuel tank that includes an easily readable gauge. At ½ load this generator has an 8-hour runtime. The starting method of this generator is manual. Most reviewers say you are not going to go past two pulls for the generator to start up. It is also fuel efficient. At 69dbA, the generator is not super quiet but it is ok to give your neighbors their peace of mind. For easier transportation and movement we recommend that you buy the optional wheel kit. It will really make your life easier.


It is a budget portable generator which can power most of your essential appliances in the home. Of course you are not going to get the extra benefits that come with the expensive ones, like very clean power. This is the best bet if you are on budget. Click here to buy this generator and read more reviews on Amazon.com.
