Description

Zoom on the WEN DF250iX

In a nutshell, the WEN DF250iX is a quiet, compact and lightweight portable inverter generator mostly geared towards:

  • Camping and tailgating hobbyists looking for a portable power source
  • Handcrafting enthusiasts who wish to work on-the-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

With its dual-fuel technology, the powerful and versatile WEN DF250iX provides an output of 120V. While gasoline-powered, it gives a running wattage of 2250W along with a peak wattage of 2500W. While propane-powered, it provides 1800 rated watts and 2000 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.

With a noise rating of 52 dBA (just slightly more noisy than a conversation at home), the inverter generator features a conventional pull-start mechanism.

The running time of the DF250iX, with its 1.2 gallon fuel capacity, can reach around 6 hours at 50% load on a full tank of gasoline (fuel consumption around 0.2 GPH). With propane, it can reach around 17 hours (estimation based on a 20 lbs tank - propane consumption around 0.28 GPH).

Delicate electronics can be plugged in an AC outlets safely, as the DF250iX generates a clean sine wave, reaching a <1.2% Total Harmonic Disruption (THD).

Outlets

The control panel provides the upcoming 2 AC outlets:

Duplex 120V 20A (5-20R)

In addition, it provides 2 DC outlets: there's two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.

Portability

As the WEN DF250iX is an inverter generator, its encased design (L19 x W11.5 x H18.2 in) offers more aesthetics than a conventional, open frame product. This modern design aims to provide an ideal power solution to recreational users.

Labeled a lightweight portable generator, the DF250iX weighs just 48.5 lbs. The product’s power can be enjoyed on-the-go, as it can be moved by a single person without trouble. It can also be carried without effort with a featured handle (molded in the case), further improving its convenience.

Features

Panel of the WEN DF250iX

The DF250iX's control panel

Several light indicators serve to show you when the oil level is too low, the generator is ready and the generator is on overload.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.

The fuel shutoff feature turns off the flow of fuel, allowing for the DF250iX 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 the carburetor, minimizing maintenance while prolonging the unit’s lifespan.

As far as security is concerned, the generator can be used with a peace of mind, as it features a low fuel automatic shutdown, an overload protection (circuit breaker) and an automatic low oil shut-off.

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).

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the WEN DF250iX also comes with several accessories, including: funnel, tool kit and propane hose.

Emissions

The WEN DF250iX 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, so it is adequate for use in forested areas.

The WEN DF250iX versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN DF250iX compare to inverter generators of similar power (between 1500 and 2500 W).

  • Since the generator weighs in at a dry weight of 48.5 lbs, the WEN DF250iX belongs in the expected weight range for inverters which can produce between 1500 and 2500 rated watts. If weight matters to you, one of the champions in this power range is the Genmax GM2000i with only 34.2 pounds.
  • As its lowest possible noise is rated at 52 dBA, this inverter generator qualifies as one of the more quiet of the products of similar type and power. If noise emissions are one of your priorities, you may be interested in the Honda EU2200i, one of the least noisy generators similarly powerful as this one, rated for 48 dBA.
  • Regarding its autonomy, the autonomy of the DF250iX, reaching around 6 hours at a 50% load, can be considered as low end, compared to other inverters of a roughly equal output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Lifan ESI 2500iER-EFI, reaching around 12 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This inverter generator has an estimated fuel consumption of roughly 0.2 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen2200, with a fuel consumption of 0.11 GPH could be in your good books.

Unlike many websites, we did our best to research each of the specs above. That being said, we are not immune to making the occasional mistake or omission. Should you notice any missing or incorrect values, don't hesitate to suggest improvements so we can address the issue.
* Propane runtime is our own estimation, based on a 20 lbs tank and NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs of propane = 1 gal of gasoline.
