WEN DF400iX - Spec Breakdown

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:

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

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.
