Description

Zoom on the WEN DF475X

The WEN DF475X is the newer version of the DF475T. It's a compact portable generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Homeowners in need of an emergency backup power for their essentials

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

Thanks to its dual-fuel technology, the WEN DF475X delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3,800W and a peak wattage of 4,750W. When propane-powered, it has 3,500 rated watts and 4,350 peak watts.

Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery included).

With a fuel capacity of 4 gallons, the DF475X can operate for around 11 hours at 50% load using gasoline (fuel consumption around 0.36 GPH), or for around 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH) using propane.

Outlets

The control panel features the following 3 AC outlets:

Duplex 120V 20A (5-20R)
120/240V 30A (L14-30R) receptacle

Furthermore, it has 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle with which you may charge your batteries with ease.

Due to the featured twist-lock L14-30R receptacle, the DF475X is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The WEN DF475X has the following dimensions: L23.2 x W17.5 x H18.5 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.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 105.8 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.

Features

The DF475X's control panel

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

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 DF475X also is packed along with the following accessories: oil and propane hose.

Emissions

The WEN DF475X 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, so it is adequate for use in forested areas.

The WEN DF475X versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN DF475X compare to dual fuel generators of similar power (between 3500 and 4500 W).

  • As its weight is 105.8 pounds, the WEN DF475X falls in the expected weight range of the dual fuel devices in the 3500-4500 rated wattage category. Regarding dry weight, one of the champions in the same power range is the WEN DF402iX, with a dry weight of only 66.1 lbs.
  • As the DF475X offers around 11 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the dual fuel 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 Westinghouse iGen4500DF, boasting with around 15 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 generator reaches an estimated fuel consumption of 0.36 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4500DF, with a fuel consumption of 0.23 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W dual fuel generators, the WEN DF475X 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.
