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.

Zoom on the DuroStar DS4400E

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

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • DIYers who wish to improve their efficiency with tools
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals who want to ensure that a power failure will not prevent them from working

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The DuroStar DS4400E's engine, 208 cc (7 hp) DuroStar OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 3500W and reaches a peak wattage of 4400W.

With a noise rating of 69 dBA (less noisy than a normal conversation), the generator features a simple traditional pull-start mechanism, but also a simple and elegant electric starter (battery included).

The fuel capacity of 4 gallons allows the DS4400E to operate for around 11.5 hours at 50% load with a full tank (fuel consumption around 0.35 GPH).

The DS4400E is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<12%).

Outlets

The control panel features the following 3 AC outlets:

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

Furthermore, it has 1 DC outlet: there's a 12V 8A output with which charging your batteries is made easy.

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 design of the DuroStar DS4400E is a typical, open frame, with the dimensions of L25 x W24 x H21 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough environments and demanding outdoor use.

As the generator's weight is 122 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, this lack of maneuverability is compensated by its wheel kit (⌀8") and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the DuroStar DS4400E

The DS4400E's control panel

The control panel of the DS4400E includes a convenient voltmeter, which provides an easy way to monitor power output anytime, helpful for the monitoring of its status and activity.

In addition to this info, a light indicator allows you to instantly see 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.

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.

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: battery charging cables, funnel and tool kit. 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, making it usable 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).

  • A weight of 122 lbs makes the DuroStar DS4400E one of the heavier devices in the 3000-4000 rated wattage range. If weight matters to you, one of the champions in this power range is the Genmax GM3300i with only 47.4 pounds.
  • This generator, with its lowest possible noise rated at 69 dBA falls into the more noisy category, compared to other devices of a similar running wattage. If noise emissions are important to you, one of the least noisy generators of this power range is the Cummins Onan P4500i with only 52 dBA.
  • The DS4400E, falls within the average autonomy range compared to generators of a roughly same power, with a run time of around 11.5 hours at a 50% load and a full tank. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Predator 4375, with 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 0.35 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you wish to further improve in the area of fuel efficiency, the Genmax GM3300i, which boasts with a gas consumption of only 0.22 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.
