Zoom on the DuroMax XP4000S
In summary, the DuroMax XP4000S is a compact portable generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- 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
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 DuroMax XP4000S's engine, 208 cc (7 hp) DuroMax OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3300W and reaches a peak wattage of 4000W.
The generator is rated for a noise of 69 dBA (less noisy than a normal conversation). Its starting mechanism is based on a simple traditional pull-start mechanism.
The fuel capacity of 4 gallons allows the XP4000S to operate for around 12 hours at 50% load with a full tank (fuel consumption around 0.33 GPH).
As the XP4000S has a relatively high THD (<12%), it is not recommended to use it to power sensitive electronic devices.
The control panel includes the following 3 AC outlets:
This DuroMax generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready.
The DuroMax XP4000S has the following dimensions: L23 x W17 x H18 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
The 92 lbs of the XP4000S's dry weight enables you to use it anywhere you will ever need. Additionally, the generator’s mobility is also improved by its open frame design, as it can be easily grabbed and shifted.
If you wish to transport the XP4000S more easily, you may also consider purchasing the official wheel kit (opens in a new tab).
The XP4000S's control center features a handy voltmeter that allows you to easily monitor power output anytime to aid you with the monitoring of its status and activity.
In addition to this info, when the oil level is too low, you will be informed by the featured light indicator.
The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the DuroMax XP4000S's package also includes these accessories: tool kit and funnel. An official storage cover is also available, as a separate purchase.
The DuroMax XP4000S 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 and thus, may be used in forested areas.
The DuroMax XP4000S versus other generators
The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP4000S compare to generators of similar power (between 2500 and 3500 W).
- As its weight is 92 pounds, the DuroMax XP4000S falls in the expected weight range of the devices in the 2500-3500 rated wattage category. In terms of weight, one of the champions in their power range is the Generac GP3300i, standing at just 59.5 lbs.
- This generator has a somewhat average expected noise for its power range, rated at 69 dBA. For those who are looking for a less noisy device, we suggest the Honda EU3000iS. With just 50 dBA, it is one of the most quiet devices in this power range.
- As the XP4000S offers around 12 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000X, boasting 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. Standing at an estimated 0.33 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.
As you can see from this interactive chart, when compared to other 2500-3500W generators, the DuroMax XP4000S 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.
The bottom line
- Several accessories included
- Decent weight (92 lbs)
- Acceptable noise (69 dBA)
- Decent run time
- Decent fuel efficiency
- No electric start

Can you add an electric start? (Asked January 30, 2021)
Not without modifying the unit, which would most likely void your warranty. You may want to have a look at the XP4400E, which has similar specs, but comes with an electric start and a wheel kit.
