Zoom on the DuroStar DS4000S
In summary, the DuroStar DS4000S is a compact portable generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- Occasional participants of outdoor events, competitions, concerts and festivals
- Handcrafting enthusiasts who wish to work on-the-go
- 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 design includes a gasoline-fueled 208 cc (7 hp) DuroStar OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3,300W and also a peak wattage of 4,000W.
With a noise rating of 69 dBA (less noisy than an office), the generator features a simple traditional pull-start mechanism.
The fuel capacity of 4 gallons allows the DS4000S to operate for up to 26 hours with a full tank (fuel consumption around 0.15 GPH).
The DS4000S is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<12%).
Outlets
The control panel features the upcoming 3 AC outlets:
Even if this DuroStar generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle.
Portability
The DuroStar DS4000S has the following dimensions: L23 x W18 x H17.5 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
With a dry weight of 92 lbs, the DS4000S can easily follow you wherever your power needs are. 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, the device’s light indicator will display if its oil levels are insufficient.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.
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, which makes it suitable for use 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).
- With a dry weight of 92 pounds, the DuroStar DS4000S finds itself in the expected weight range for generators able to produce between 2500 and 3500 rated watts. In terms of weight, one of the champions in their power range is the Pulsar PGD40iSCO, standing at just 46 lbs.
- As this generator has its lowest possible noise of 69 dBA, it should be considered noisier compared to its peers of a comparable running wattage. 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.
- The DS4000S provides one of the highest run time among similarly powerful devices, reaching up to 26 hours at 25% load.
- 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. This generator, with an estimated fuel consumption of just 0.15 GPH (gallon per hour) at 25% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3500P is a device you could look out for.
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
- High run time
- Fuel efficient
- Decent weight (92 lbs)
- No electric start
- On the noisy side (69 dBA)
