Description
Zoom on the DuroStar DS4000S
In a few words, the DuroStar DS4000S is a compact portable generator perfectly suited 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 in need of an emergency backup power for their essentials
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.
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 3,300W and a peak wattage of 4,000W.
The generator is rated for a noise of 69 dBA (less noisy than background music). Its starting mechanism is based on a classic hand-operated recoil starting mechanism.
Featuring a 4 gallons fuel tank, the DS4000S guarantees continuous power for up to 26 hours on a full tank (fuel consumption around 0.15 GPH).
Due to the relatively high THD (<12%) of the DS4000S, it is advised against using it for powering sensitive electronic devices.
Outlets
The control panel is equipped with the following 3 AC outlets:
This DuroStar generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready.
Portability
Measuring L23 x W18 x H17.5 in, the classic open frame construction of the DuroStar DS4000S provides stability while enabling convenient maintenance access to components and adequate air cooling. The design is ideal for rough environments and demanding outdoor use.
The 92 lbs of the DS4000S's dry weight enables you to use it anywhere you will ever need. Moreover, the open frame design of the generator simplifies grabbing and relocating it.
You also have the option to purchase the official wheel kit (opens in a new tab) to aid in the easier transportation of the DS4000S.
Features
The DS4000S's control panel
Integrated into the control center of the DS4000S are a handy voltmeter that allows you to easily monitor power output anytime, facilitating the monitoring of its status and activity.
In addition to this info, the device's light indicator will illuminate to indicate if the oil level is too low.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
Regarding security, the generator comes with an automatic low oil shut-off and an overload protection (circuit breaker), providing peace of mind during operation.
In addition to the traditional documentation and an owner's manual (opens in a new tab) to help you get started promptly, the DuroStar DS4000S also includes several accessories: tool kit and funnel. An official storage cover is also available, as a separate purchase.

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).
- As its weight is 92 pounds, the DuroStar DS4000S falls in the expected weight range of the devices in the 2500-3500 rated wattage category. If weight is a key factor for your needs, the Pulsar PGD40iSCO is noteworthy for being one of the top contenders in this power range, with a dry weight of 46 pounds.
- This generator, with its lowest noise level at 69 dBA, is noisier than most generators of comparable running wattage. If you wish to prioritize minimal noise, the Honda EU3000iS stands out as one of the quietest options among generators of similar power, with a rating of 50 dBA.
- At 25% load, the DS4000S boasts one of the highest run times than most similarly powerful products, reaching up to 26 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. At an estimated fuel consumption of 0.15 GPH (gallon per hour) at 25% load, this generator is a rather fuel-efficient one within its wattage category. If minimizing fuel usage is one of your key priorities, the Energizer eZV3500P is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.13 gallons per hour.
The bottom line
- Several accessories included
- High run time
- Fuel efficient
- Decent weight (92 lbs)
- No electric start
- On the noisy side (69 dBA)
