Description
Zoom on the DuroStar DS4000S
In a nutshell, the DuroStar DS4000S is a compact portable generator mostly geared towards:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- People occasionally participating in outdoor fairs, festivals or events
- Amateur DIY lovers
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The DuroStar DS4000S
The DuroStar DS4000S's core is the 208 cc (7 hp) DuroStar OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3300W and a peak wattage of 4000W.
The generator is rated for a noise of 69 dBA (less noisy than background music). Its starting mechanism is based on a simple traditional pull-start mechanism.
With a full tank, the DS4000S can operate for around 12 hours at 50% load (fuel consumption around 0.33 GPH), thanks to its fuel capacity of 4 gallons.
The powering of sensitive electronic devices with the DS4000S is not recommended due to its relatively high THD (<12%).
Outlets
The control panel features the upcoming 3 AC outlets:
This DuroStar generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor.
Portability
With its dimensions of L23 x W18 x H17.5 in, the conventional, open frame design of the DuroStar DS4000S offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.
The DS4000S can be taken anywhere with you, thanks to its weight of 94 lbs. Furthermore, the open frame of the generator further helps when holding and moving it to a different place.
It is also possible to purchase the official wheel kit (opens in a new tab) to help you transport the DS4000S more easily.
Features
The DS4000S's control panel
The DS4000S's control center features a convenient voltmeter, which provides an easy way to monitor power output anytime to aid you with the monitoring of its status and activity.
In addition to this info, a light indicator allows you to instantly see if its oil levels are insufficient.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the DuroStar DS4000S's package also includes these accessories: funnel and tool kit. An official storage cover is also available, as a separate purchase.
Emissions
The DuroStar DS4000S is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor, making it usable in forested areas.

The DuroStar DS4000S versus other generators
The following charts are provided to give you an idea of how some of the key specs of the DuroStar DS4000S compare to generators of similar power (between 2500 and 3500 W).
- Regarding its weight, the DuroStar DS4000S only weighs in at 94 pounds, which means it's one of the lighter generators in the 2500-3500 rated wattage range. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
- This generator has a somewhat average expected noise for its power range, rated at 69 dBA. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU3000iS with only 50 dBA.
- Offering around 12 hours of running time on a full tank at 50% load, the DS4000S is within the average autonomy range of similarly powerful generators. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000X, reaching around 16 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. Standing at an estimated 0.33 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.
Price comparison
As you can see from this interactive chart, when compared to other 2500-3500W generators, the DuroStar DS4000S is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.
The bottom line
- Inexpensive
- Several accessories included
- Lightweight for its kind (94 lbs)
- Acceptable noise (69 dBA)
- Decent run time
- Decent fuel efficiency
- No electric start
