Description

Zoom on the WEN DF400iX

The WEN DF400iX is the newer version of the popular DF400i. It's a quiet and compact portable inverter generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and 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
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go

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 dual-fuel technology of the WEN DF400iX allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3200W and a starting wattage of 4000W. If propane-powered, it gives 2900 rated watts and 3200 starting watts. Additionally, as the generator is parallel capable (parallel kit not included), it can be linked to a second unit for more power.

WEN’s Auto Fuel Selection technology automatically selects the fuel source (LPG or gasoline) depending on availability and prioritizes LPG. Thus, if a propane tank with enough LPG is connected, the generator will automatically use LPG. If no propane tank is connected, or if there is not enough LPG remaining in the tank, the generator will use gasoline.

At a noise rating of 58 dBA (less noisy than a refrigerator), this inverter generator can be started via a simple traditional pull-start mechanism, or a simple and elegant electric starter (battery included).

The DF400iX, with a fuel capacity of 2.2 gallons, reaches a run time of around 8.5 hours at 50% load utilizing gasoline (fuel consumption around 0.26 GPH). Alternatively, it can reach a run time of around 9 hours (on a 20 lbs tank - propane consumption around 0.52 GPH) with propane.

The DF400iX generates a clean sine wave: providing <1.2% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel features the upcoming 3 AC outlets:

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

In addition, it provides 3 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle allowing you to easily charge your batteries and two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this WEN generator is RV Ready.

Portability

As the WEN DF400iX is an inverter generator, its encased design (L23.2 x W18 x H20.1 in) offers more aesthetics than a conventional, open frame product. The generator has a contemporary design, convenient for recreationally generating power.

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 100 lbs. Nevertheless, thanks to its set of 2 wheels and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the WEN DF400iX

The DF400iX's control panel

A digital data center, one of the features of the DF400iX's control panel, gives you information on the voltage, power output, frequency, fuel level and lifetime run hours, and thus, is helpful for the monitoring of its activity and status.

In addition to this info, the device’s light indicators will display if the oil level is too low, the generator is ready and the generator is on overload.

The fuel shutoff feature turns off the flow of fuel, allowing for the DF400iX to use up the remaining fuel from the carburetor before automatically shutting down. This helps fight the build-up and blockages caused by stagnant fuel inside of the carburetor, minimizing maintenance while prolonging the unit’s lifespan.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

The unit also benefits from WEN's CO Watchdog carbon monoxide detection. This system measures the accumulation of poisonous CO gas while the generator is running. If the level of CO gas gets too high, the CO Watchdog system will automatically shut down the generator. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the WEN DF400iX also is packed along with the following accessories: funnel, tool kit and propane hose.

Emissions

The WEN DF400iX is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, so it is adequate for use in forested areas.

The WEN DF400iX versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN DF400iX compare to generators of similar power (between 2500 and 3500 W).

  • Since the generator weighs in at a dry weight of 100 lbs, the WEN DF400iX belongs in the expected weight range for devices which can produce between 2500 and 3500 rated watts. If weight matters to you, one of the champions in this power range is the Genmax GM3300i with only 47.4 pounds.
  • With a lowest noise rating of 58 dBA, the inverter generator is one of the more quiet of the generators of similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU3000iS, whose lowest noise levels reach just 50 dBA.
  • Regarding its autonomy, the autonomy of the DF400iX, reaching around 8.5 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. 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 Predator 4375, with around 16 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This inverter generator is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.26 GPH (gallon per hour) at 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you could look out for.

Price comparison

As you can see from this interactive chart, when compared to other 2500-3500W generators, the WEN DF400iX is on the average side of the price range.

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