Zoom on the DuroStar DS4000S
In summary, the DuroStar DS4000S is a compact portable generator especially useful for:
- 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 houses a 208 cc (7 hp) DuroStar OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3300W along with a peak wattage of 4000W.
The generator features a conventional pull-start mechanism. It is rated for a noise of 69 dBA (less noisy than an office).
With a fuel capacity of 4 gallons, the DS4000S may run for around 12 hours at 50% load with a full tank (fuel consumption around 0.33 GPH).
The DS4000S is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<12%).
Outlets
The control panel provides the upcoming 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
The DuroStar DS4000S has a conventional, open frame design, of the following dimensions: L23 x W18 x H17.5 in, which offers support and allows it to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.
The DS4000S can be taken anywhere with you, thanks to its weight of 94 lbs. Additionally, the generator’s mobility is also improved by its open frame design, as it can be easily grabbed and shifted.
Features
The DS4000S's control panel
The DS4000S and its control panel include a convenient voltmeter, which provides an easy way to monitor power output anytime. This feature comes handy when monitoring its status and activity.
In addition to this info, a light indicator serves to show you when its oil levels are insufficient.
Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the DuroStar DS4000S, the following accessories are also included: tool kit and funnel.
Emissions
The DuroStar DS4000S is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
Moreover, it features a spark arrestor and therefore, can be used in forested areas.
Product Videos
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 94 pounds, the DuroStar DS4000S falls in the expected weight range of the devices in the 2500-3500 rated wattage category. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
- The generator can be considered average in its noise for its power category, as it is rated at 69 dBA. For those who are looking for a less noisy device, we suggest the Honda EU3000iS. With just 50 dBA, it is one of the most quiet devices in this power range.
- 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. This generator reaches an estimated fuel consumption of 0.33 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.
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
- Decent weight (94 lbs)
- Acceptable noise (69 dBA)
- Decent run time
- Decent fuel efficiency
- No electric start
