- Why Choose DuroStar Generators?
When shopping for a portable generator, you need a brand with a reputation for manufacturing reliable products. DuroStar is one such brand. This article gives you a brief overview of the DuroStar brand and why you should consider buying its generators. We will also provide an in-depth review of the DuroStar DS4000S 4000-Watt Gas Portable Generator to help you make an informed decision if you wish to buy it. Read on to discover more.
The Ultimate DuroStar DS4000S 4000-Watt Gas Portable Generator is one of the best buys if you are looking for a unit with modest power output for home or remote use.
The DuroStar DS4000S portable generator has a peak power rating of 4,000 watts and running wattage of 3,300 watts. This power is enough to run most home appliances such as refrigerators, lighting, sump pumps, TVs, dishwashers, electric cookers, and other kitchen appliances. You can also use it to run your DIY projects during power outages or in remote places. This generator can run power tools such as saws, grinders, and corded drills. It also spells good news to outdoor lovers as it has enough output to power RVs and most camping equipment.
However, before you load your appliances to this portable generator, it is important to establish whether this workhorse can handle your total workload. For starters, the total wattage of your appliances should not exceed 3,300 watts, which is the running output of the DuroStar DS4000S. Add the running wattages of the home appliances you want to run with this portable generator to know your total load.
In cases where the rated wattage is not indicated on the appliances, multiply its rated voltage with its amperage to know its rated output. You may use online calculators for quicker computations. Avoid overloading your generator as such a move will cause it to trip and can damage the unit.
Another factor you need to consider is the peak wattage of the generator. Always ensure that you do not connect an appliance with a peak wattage greater than 4,000 watts. If this happens, the generator will run, but the appliance will not start. Although most home appliances have lower peak wattages, industrial machines may require high starting power. Therefore, take note of this fact when using the generator to operate high-wattage appliances.
Ergonomics and Transportation
The DS4000S features an open-frame design that makes it easy to grab and move it from one place to another. It weighs 94 pounds, and so two people can carry it with ease. However, if you are likely to operate this unit alone, consider buying the DuroStar DS4000S-WK Wheel Kit for the DS4000S.
This kit comes with two never-flat tires and a fold-down handle that is easy to install. You don’t have to worry about the tires going flat, especially when working a remote worksite with harsh conditions. Also, its all-metal construction makes the DS4000S an excellent pick if you are looking for a generator to use in rugged conditions.
Unfortunately, this generator doesn’t come with an electric start mechanism. However, the pull-start works just fine. Just a few tries and the engine kicks into action. Just keep the unit clean and well serviced to ensure it’s always ready for use when you need it.
The DuroStar DS4000S 4000-Watt 7 HP portable RV Gas Generator runs on a 208 cc DuroStar OHV four-stroke engine. It runs on gas and has a maximum rpm of 3,600. This engine has average fuel efficiency and consumes 0.33 gallons per hour at a 50% load. With a fuel tank of 3.96 gallons, the DS4000S delivers 12 hours of runtime at 50% load.
If you operate this generator at full load, the runtime drops to 8 hours, which is equivalent to a whole day of work at a worksite. On the other hand, if you use this unit as a backup in your home, it can hold up for several hours until your grid power is restored.
The engine has a noise level of 69dB(A), which is quieter than most generators that are louder than 70dB(A). This feature means tolerable noise for your neighbors, which is a big plus in residential areas or campsites. It is also important to mention that the generator has a decent electrical power conversion efficiency thanks to an all-copper winding design.
The control panel of the DS4000S generator is simple to understand. It features an analog voltmeter that allows you to see the output voltage immediately. It also has a low-oil indicator just below the engine switch. This indicator lights up when the engine is dangerously low.
The power outlets include two 120V 20A household ports and one 120V 30A(L5-30R) twist-lock outlet. Although the engine lacks an RV-ready port, you can easily use an L5-30P to TT-30R adaptor and hook it to the L5-30R outlet to power your RV.
The DuroStar DS4000S generator comes with a surge arrestor that protects your generator from power surges. It has a resettable circuit breaker switch that cuts off the power supply in case of an overload. Ensure you reset this switch after an overload incident to ensure that the generator stays protected.
However, the best approach is to avoid overloading your generator. Another safety feature that comes with the DS4000S is the low-oil shutoff. If the engine oil gets below the required level, this safety mechanism shuts off the generator. This way, your engine is protected and its longevity enhanced.
Where Can You Use the DuroStar DS4000S Generator?
As stated earlier, the DS4000S generates a lot of power which you could use to power your home. However, it is critical to mention that this unit may not power your whole house, and you may need to connect only the critical appliances. If you wish to connect this generator to your house mains, ensure that you work with a qualified technician to install a transfer switch.
With the transfer switch in place, you can tap electricity directly through your wall power sockets. In the same way, you can use an adapter to make this generator RV-ready. This way, you will be able to power your RV and access electricity through its wall sockets. Additionally, the multiple power outlets allow you to connect several power tools at a worksite.
Another crucial factor to consider is the type of appliances you can run with this generator. The DS4000S has a high total harmonic distortion (THD<12%) on its electrical signal. This feature makes the portable generator unsuitable for powering sensitive electronics such as computers, lab equipment, and medical devices. For this reason, you may need to buy an automatic voltage regulator to smoothen the electrical signal.
Care and Maintenance of the DuroStar DS4000S
When you buy the DuroStar DS4000S portable generator, familiarize yourself with its salient features to enable you to operate it properly. Start by reading the DuroStar DS4000S manual that comes with the generator. If your delivery doesn’t come with the user manual, you can download it from the company website. The best way to keep your generator sound and ready to run whenever you need it is by following the manufacturer’s recommended care and maintenance routine.
It is important to mention that the frequency of servicing your generator will depend on how often you use it and the load you apply. If you consistently run the DuroStar DS4000S at maximum load, its rate of wear and tear will be high, requiring you to service it frequently.
You should check the engine oil level before each use and add if it’s low. Change it every 20 hours or every month, whichever comes first. Also, the air cleaner needs to be checked before each use and changed after every 50 hours or three months. Clean the sediment cup, spark arrestor, and spark plug every six months or 100 hours. After 300 hours of use or every 12 months, check and adjust the idle speed and valve clearance and change the spark plug. You will need to clean the combustion chamber every 500 hours of operation. Other parts that need cleaning every six months or 100 hours are the fuel tank and filter.
Some procedures, such as cleaning the combustion chamber, are complex and need qualified professionals to undertake. You can damage the generator if the maintenance process is done wrongly and invalidate your warranty. For this reason, take your unit to a DuroStar-approved service center for major maintenance routines.

However, propane is a cleaner fuel than gasoline. It has a longer shelf life than gas and can provide a longer runtime if you have a large fuel reservoir. Durostar doesn’t provide inverter generators and, therefore, its models may not be good for sensitive electronics.
