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 compact portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • DIYers who wish to improve their efficiency with tools
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 core is the 208 cc (7 hp) DuroStar OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 3500W and a peak wattage of 4400W.

The generator features a conventional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 69 dBA (less noisy than an office).

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 upcoming 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 allowing you to easily charge your batteries.

As it features a twist-lock L14-30R receptacle, the DS4400E is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The design of the DuroStar DS4400E is a typical, open frame, with the dimensions of L24 x W17 x H17 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 125 pounds. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀8") and its folding handle, once it is placed on 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 handy voltmeter that allows you to easily monitor power output anytime.

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

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the DuroStar DS4400E also comes with some accessories: funnel, battery charging cables and tool kit are included. An official storage cover is also available, as a separate purchase.

Emissions

The DuroStar DS4400E 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 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).

  • Considering its dry weight of 125 pounds, the DuroStar DS4400E is one of the heavier generators producing between 3000 and 4000 running 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. For those who are looking for a less noisy device, we suggest the Cat INV4000E. With just 51 dBA, it is one of the most quiet devices in this power range.
  • Given that the DS4400E reaches an autonomy of around 11.5 hours with a full tank and at 50% load, it is placed within the average autonomy range of similarly powerful generators. 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 Honda EB4000X, with around 16 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. 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 acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.

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.
