    Powerful and Reliable

    In order to provide as much value for its size as possible, the DS4400E generator makes use of its 212cc engine to push out a remarkable 3,500 watts of running power. This translates to stable performance across the board, no matter what your needs are.

    While traditional home backup units rely on aluminum windings to reduce costs, DuroStar generators house 100% copper windings. As a superior heat conductor, copper spreads heat to keep temperatures optimal and prevent the unit from damaging itself over time, while aluminum quickly overheats and has inferior heat dissipation.

    Built for camping lovers and professionals alike, the 4,400-watt portable generator holds one more ace up its sleeve. Using innovative MX2 Power Boost Technology, this unit is capable of doubling the baseline 120V voltage to keep up with heavy loads such as powering heavy-duty power tools.

    All of these characteristics combined make the DuroStar DS4400E a reliable and robust option for homeowners during a power outage and workers on a job site.

    Extended Runtime

    When it comes to outrunning your needs, the 4,400-watt portable generator is truly a unit you can count on. The DuroStar DS4400E makes efficient use of its 3.96-gallon fuel capacity to accommodate all levels of use. For reference, this gas portable generator can last for as long as 25 hours at low load, and 10 hours at half load.

    Combined with its compact size, it presents itself as a no-brainer for outdoors enthusiasts and professionals looking for a reliable option.

    The DS4400E also features a smart idle control feature that automatically cuts down engine speeds when it detects it’s not being used, saving fuel, and cost, and extending runtime.

    EPA and CARB-approved

    To ensure the safety of its users, DuroStar generators comply with strict eco-conscious guidelines provided by The Environmental Protection Agency (EPA) and California Air Resources Board (CARB). These directives aim to reduce toxic emissions and by following them, the 4,400-watt portable generator is safe to use in close proximity, making it perfect for work sites and occasional fairs, family gatherings, or festivals.

    By being both EPA and CARB-approved, the DS4400E produces far lower levels of carbon, offering a worry-free experience and peace of mind when using the unit.

    Geared for Endurance

    From a build quality standpoint, the DuroStar DS4400E is a beast. Featuring full metal construction and heavy-duty frames, this 4,400-watt portable generator can endure years of use under harsh weather conditions and work perfectly even after being roughed up a bit.

    In addition, the DS4400E features a grippy set of semi-solid tires that will never run flat, easing the pain of moving the 122lbs unit around. Conveniently, this gas portable generator also comes with foldable handles to complement the ease of use.

    Fully Featured Power Panel

    Providing maximum compatibility, the fully featured power panel includes different outlets to accommodate different uses, making it ideal for charging external batteries, powering high-amperage power tools, and small and large appliances.

    The DuroStar DS4400E is also transfer switch-ready, meaning it can be directly plugged into your home breaker box and immediately begin producing power to your household through an L14-30R receptacle.

    In order to prioritize the safety of its users, the unit also features a circuit breaker that shuts down the engine in case of overloads while the low oil shutoff does so when oil levels are low.
