The product that we will review here is a portable generator by DuroStar, the company that has made other fuel generators, as well as two snow throwers. Like any product of its type, it is meant to serve as a source of gas and electricity in cases where no other source is available — such as when you are out camping in the woods, or even to power your RV — or when the primary source for your residence is off due to a power failure. In this article, we shall briefly describe some of the features of this machine — what comes in the package, what the main features are and how many previous buyers have found it.
The package, as it comes to the purchaser, consists of three items:
- the power generator itself
- a tool kit
- an instruction manual
The overhead valve engine is air-cooled and has horsepower of seven. The heavy-duty frame is made of steel with four fully-isolated mounts, allowing the machine to operate smoothly and quietly. Capacity is four gallons, and at half-load the power generator has a run time of eight hours. It runs on gasoline and must be started manually. A wheel kit for the DS4000S may also be purchased separately.
Operating the machine
To start the power generator, turn it on and pull the starter rope, just as you would for a lawn mower. There is also a volt meter and two outlets in which the items to be powered may be plugged.

As with any power generator, you must taken certain safety measures when using this product. Obviously, it should be kept out of reach of children and also away from any source of heat or flame. Likewise, avoid lighting a flame near the generator.
This power generator is not CARB-compliant and therefore cannot be sold in California.

Average Amazon customer review for the DuroStar DS4000S portable power generator is four and a half stars. Buyers have found it easy to set up, and it starts after just one pull. One customer even bought this machine in preparation for hurricane Irene (which was one of the biggest and most destructive ever to hit the country). Another, who lives in a flood-prone region, chose this one after his old one had stopped working.
