About DuroStar DS4000S Portable Generator
77% liked the sturdy construction, but 23% found it flimsy
The product had dents on the heavy steel frame and side cover, but it started on the first pull and runs quietly and smoothly.
I suggest that a second round of quality control could have prevented the broken weld.
This generator seems to be cheaply built and probably made in China.
88% liked the fuel efficiency, but 12% faced issues
I was surprised by the fuel economy of the generator. It can run for an entire day on about 3 gallons of gas due to its large tank, which only needs to be filled once or twice a day.
I was pleasantly surprised that the generator ran for 12 hours on just 4 gallons of fuel.
At year three, rust started accumulating in my gas tank.
76% found maintenance straightforward
I gave the generator some dry-run time to break it in and proof load capacity.
I change the oil once a year if it has been in storage and every 12 hours if using for an emergency.
It is important to drain the fuel out of the tank and carburetor when putting the generator away.
92% were satisfied with the quiet operation, but 8% were bothered
The generator is great but not as quiet as stated.
The generator is a bit loud for campgrounds. I measured the noise level to be 75db next to it and 53db at 50ft.
I rated the generator 3 out of 5 stars for noise level as it is a bit loud.
I find the unit to be extremely loud and it shakes uncontrollably.

77% found it easy to transport, but 23% found it bulky
It would be nice if it came with wheels, but it is difficult to move around. However, I did not buy it for portability, but for emergencies in power outages.
82% appreciated the high power output, but 18% found it insufficient
During hurricane Idalia, I was able to power 3-4 fans, a refrigerator, and several lights with the generator.
I can run a 15000 btu air conditioner and lights in the camper with the generator's power.
I connected a volt/ohm meter to the generator and found that the voltage fluctuates +- 10 volts with a load around 1000 watts.
79% appreciated the long runtime, but 21% found it limited
I started the generator with little trouble and it ran for 3 days straight.
I can run the generator for 8-10 hours on a tank of gas, although fuel is expensive.
After only a week of use, the generator is performing decently.
My generator's runtime is not 11 hours per full tank, but more like 8 or 9 hours.
84% found it easy to start up, but 16% experienced difficulties
I would have preferred an electric start model, but overall I am happy with my purchase. The machine is very simple and easy to start by pulling.
I have to remember how to configure it for start up each time as it has been so long, but it always fires up and runs smoothly and quietly.
I set up the generator in around 10 minutes and it started on the first pull. I ran my sump pump, fridge, a fan, and even charged my cell phone. I was about to run the air conditioner too, but power came on in about 2 hours. It's a great product, easy to use, and it saved me from a disaster.
Starting the generator is difficult and requires two people.
84% found it resistant to various weather conditions, but 16% experienced issues
I was able to avoid a disaster when the sump pump stopped working in my basement and the generator, which was still in the box in my garage, started on the first pull.
Running a generator in wet conditions can result in electrocution.
