Durostar DS4000S Reviews

Consumer Feedback on DuroStar DS4000S 4000 Watt Portable Gas Generator


Reviewers were pleasantly surprised at the power and run time for a generator of this size. Overall, reviewers were able to power a refrigerator and additional lights, outlets, and other small appliances on this generator. One reviewer said they could run the generator for 13 hours on one tank of gas. Many reviewers loved how inexpensive the generator was for how much power they received. The length of time they were able to run things in the home for the price was a huge bonus for the generator. The four gallon tank actually runs on average for 10 hours, more or less about how much load you are putting on the mechanism. Reviewers thought the time was very impressive, a major recommendation for the generator.


Not only does this generator do well in power outage situations, but it’s perfect for powering an RV. One reviewer said he started the generator right out of the box, let it idle for three minutes, and then plugged it into his camper. He was able to power an LCD TV, stereo with six speakers, refrigerator, lights, vent fan, and microwave with no problems whatsoever.


Reviewers also loved how quiet the generator was. Gas powered generators are expected to be very loud, but the muffler on the DuroStar Generator does its job perfectly. One reviewer said that the generator was quieter than his lawnmower by far. Another said they put their ear right next to the generator while running and said it was not at all uncomfortable. The noise level is very low for a 3,300 watt generator. Many reviewers were also impressed with how the generator started on the first pull out of the box.


Reviewers also complimented the quality of construction for the generator. Everything, down to the paint, is high quality and well fitted. Reviewers liked that the engine had rubber mounts and the large heavy steel muffler. Reviewers also complimented the sturdy gauge steel with rubber pads that help dampen vibration.


Consumer Complaints of the DuroStar DS4000S 


Complaints about the generator were small, or individual cases. About half of the low rated reviewers said they did not receive a fuel gauge as advertised, which may be a problem for a certain batch of generators. It seems the problem is corrected now. Out of the low rated reviews, there were many complaints about the packaging, but there are also many 5 star reviews that had no issues with it.


One complaint about the generator was the location of the oil fill. Reviewers complained that the location was a huge design flaw when trying to get the generator working during a storm. A reviewer recommended buying an all-purpose or transmission fluid funnel to make filling the generator with oil easier.


The generator offers an option wheel kit, which reviewers complained was a pain to put together. The difficulty came from the location of the bolts and the different wrench sizes needed. However, the same reviewers said the wheels are extremely helpful when using the generator.


Some people complained about the generator not having a wattage meter. Other reviewers have argued this complaint, saying it is easy to know how many watts you are using if you look at how much has is used. For example, if four gallons of gas are gone in eight hours that is a full load. If it is gone in 16 hours, then it is half load.


Is The DuroStar DS4000S Excellent Value


The DuroStar DS4000S Gas Powered Portable Generator has overwhelmingly positive reviews. For the watts, the generator does a spectacular job of powering key appliances. Reviewers loved how quiet it was and its ability to run for much longer than the manufacturer advertised. While the product description says the generator runs for eight hours, many reviewers reported its ability to run between 10 and 16 hours, depending on how many appliances they had the generator powering. The complaints about the generator were few, easily rectified by suggestions from other reviewers. Overall, the DuroStar DS4000S 4,000 Watt 7.0 HP OHV 4-Cycle Gas Powered Portable Generator is the perfect, affordable solution for back-up home power or RV power.
