Description
Zoom on the DuroStar DS4400E
To sum up, the DuroStar DS4400E is a portable generator tailored for:
- RV travellers who wish to upgrade their experience to another level
- 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
- Professionals who want to ensure that a power failure will not prevent them from working
Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.
Power & Run Time
With a 212 cc (7 hp) DuroStar OHV 4-stroke engine, the DuroStar DS4400E operates on gasoline, providing 120/240V, with a running wattage of 3,500W and a starting wattage of 4,400W.
At a noise rating of 69 dBA (less noisy than a normal conversation), this generator can be started via a manual recoil starter system, or a practical and straightforward electric starter (battery included).
With a full tank, the DS4400E can operate for up to 25 hours (fuel consumption around 0.16 GPH), thanks to its fuel capacity of 4 gallons.
The DS4400E is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<12%).
Outlets
The control panel is equipped with the following 3 AC outlets:
Moreover, it boasts 1 DC outlet: there's a 12V 8A output enabling simple battery charging for added ease.
Since it boasts a twist-lock L14-30R receptacle, the DS4400E is engineered to be transfer switch ready, ensuring easy integration with your breaker box to provide backup power to your home during outages.
Portability
At L25 x W24 x H21 in, the standard open frame design of the DuroStar DS4400E delivers stability alongside easy maintenance access to components and good air cooling. 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
To help you monitor the DS4400E's status and activity, its control panel is equipped with a convenient voltmeter, which provides an easy way to monitor power output anytime.
In addition to this info, the generator's light indicator provides visual feedback when the oil level is too low.
The built-in fuel gauge of the generator ensures simple and quick gas level assessments.
From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the DuroStar DS4400E's package also includes these accessories: battery charging cables, tool kit and funnel. An official storage cover is also available, as a separate purchase.
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).
- Weighing 122 lbs, the DuroStar DS4400E is one of the heavier generators within the 3000-4000 rated wattage bracket. If weight is your top priority, one of the champions in this power category is the Pulsar PGD40iSCO, weighing just 46 pounds.
- The generator's noise output, rated at 69 dBA, falls within the average range expected for devices in its power range. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen4500DF with only 52 dBA.
- The DS4400E provides a higher run time than similarly powerful devices, reaching up to 25 hours at 25% load. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the DuroStar DS4000S, which is able to run for 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. This generator can be considered as fuel-efficient, due to its low estimated fuel consumption of only 0.16 GPH (gallon per hour) at 25% load, within the aforementioned wattage range. If you're placing a high priority on fuel consumption, the Energizer eZV3500P, with a low fuel consumption rate of 0.13 GPH, could be an option to consider.
The bottom line
- Several accessories included
- GFCI Outlets
- Electric start
- High run time
- Fuel efficient
- Acceptable noise (69 dBA)
- No remote start
- On the heavy side (122 lbs)
