Description

The DuroStar DS4400E 4,400 watt generator is the #1 selling generator available from DuroStar. Powered by a 7HP DuroStar engine, this model features a fully loaded power panel, electric start, and much more. (source: DuroStar (opens in a new tab))

Zoom on the DuroStar DS4400E

In a nutshell, the DuroStar DS4400E is a portable generator mostly geared towards:

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • DIYers who wish to improve their efficiency with tools
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals who want to ensure that a power failure will not prevent them from working

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The DuroStar DS4400E's design includes a gasoline-fueled 208 cc (7 hp) DuroStar OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 3500W and also a peak wattage of 4400W.

Enjoying a noise rating of 69 dBA (less noisy than a normal conversation), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a simple and elegant electric starter (battery included).

With a fuel capacity of 4 gallons, the DS4400E may run for around 11.5 hours at 50% load with a full tank (fuel consumption around 0.35 GPH).

The quite high THD (<12%) of the DS4400E makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel features the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

It also sports 1 DC outlet: there's a 12V 8A output allowing you to easily charge your batteries.

Due to the featured twist-lock L14-30R receptacle, the DS4400E is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The DuroStar DS4400E has a conventional, open frame design, of the following dimensions: L25 x W24 x H21 in, which offers support and allows it to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 122 lbs. Nevertheless, thanks to its wheel kit (⌀8") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

The DS4400E's control panel

The DS4400E's status and activity may be monitored conveniently via the control panel, as it features a convenient voltmeter, which provides an easy way to monitor power output anytime.

In addition to this info, a light indicator shows you if its oil levels are insufficient.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the DuroStar DS4400E also is packed along with the following accessories: funnel, tool kit and battery charging cables. An official storage cover is also available, as a separate purchase.

Emissions

The DuroStar DS4400E is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

The DuroStar DS4400E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroStar DS4400E compare to generators of similar power (between 3000 and 4000 W).

  • Having a dry weight of 122 lbs, the DuroStar DS4400E belongs in the expected weight range for generators which produce 3000 to 4000 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • Since the generator's noise is rated at 69 dBA, it has the roughly average expected noise for a device of similar power. If noise emissions are one of your priorities, you may be interested in the Cat INV4000E, one of the least noisy generators similarly powerful as this one, rated for 51 dBA.
  • The DS4400E, offering a run time of around 11.5 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000X, as it provides around 16 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. Standing at an estimated 0.35 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 3000-4000W generators, the DuroStar DS4400E 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.
