Zoom on the DuroMax XP4000S

In summary, the DuroMax XP4000S is a compact portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The DuroMax XP4000S in use

The DuroMax XP4000S

The DuroMax XP4000S houses a 208 cc (7 hp) DuroMax OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3,300W along with a peak wattage of 4,000W.

At a noise rating of 69 dBA (less noisy than background music), the generator is started via a conventional pull-start mechanism.

With a fuel capacity of 4 gallons, the XP4000S may run for up to 26 hours with a full tank (fuel consumption around 0.15 GPH).

As the XP4000S has a relatively high THD (<12%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel features the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle

Even if this DuroMax generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle.

Portability

The design of the DuroMax XP4000S is a typical, open frame, with the dimensions of L23 x W17 x H18 in, offering support and stability and enabling the possibility of raising it above ground level. The device has been designed for tough environments and demanding outdoor use.

With a dry weight of 92 lbs, the XP4000S can easily follow you wherever your power needs are. Moreover, grabbing and moving this product is made even easier by its open frame design.

The official wheel kit (opens in a new tab) can be bought separately, if you need additional help in transporting the XP4000S.

Features

Panel of the DuroMax XP4000S

The XP4000S's control panel

The XP4000S's status and activity may be monitored conveniently via the control panel, as it features a convenient voltmeter, which provides an easy way to 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.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the DuroMax XP4000S also comes with several accessories, including: tool kit and funnel. An official storage cover is also available, as a separate purchase.

Emissions

The DuroMax XP4000S 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 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).

  • Having a dry weight of 92 lbs, the DuroMax XP4000S belongs in the expected weight range for generators which produce 2500 to 3500 rated watts. If weight is your top priority, one of the champions in this power category is the Pulsar PGD40iSCO, weighing just 46 pounds.
  • If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 69 dBA can be considered somewhat noisy. If noise emissions are one of your priorities, you may be interested in the Honda EU3000iS, one of the least noisy generators similarly powerful as this one, rated for 50 dBA.
  • As the XP4000S features an autonomy of up to 26 hours at 25% load, it has one of the highest run times in comparison to the other generators of its power range.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator, with an estimated fuel consumption of just 0.15 GPH (gallon per hour) at 25% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Energizer eZV3500P, which has a fuel consumption of only 0.13 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from these interactive charts, when compared to other 2500-3500W generators, the DuroMax XP4000S is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

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.
