Description

Zoom on the WEN DF623X

In summary, the WEN DF623X is a portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • 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

Thanks to its dual-fuel technology, the WEN DF623X delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 5000W and a peak wattage of 6250W. When propane-powered, it has 4500 rated watts and 5625 peak watts.

This generator features a conventional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included).

As for its running time, the DF623X, along with its 2.9 gallons fuel capacity, can run for around 6 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.48 GPH). If propane is used, it can operate for around 9.3 hours (on a 20 lbs tank - propane consumption around 0.51 GPH).

Outlets

The control panel features the following 4 AC outlets:

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

Additionally, it features 1 DC outlet: there's a 12V 10A (cigarette lighter style) receptacle allowing you to easily charge your batteries.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this WEN generator is RV Ready. In addition, since the DF623X bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

With its dimensions of L26.1 x W23.4 x H22.1 in, the conventional, open frame design of the WEN DF623X offers stability and allows 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 132 lbs make it incredibly difficult to manually lift and transport. Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

Panel of the WEN DF623X

The DF623X's control panel

The control panel of the DF623X includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), 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).

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the WEN DF623X's package also includes these accessories: propane hose, tool kit, funnel and oil. An official storage cover is also available, as a separate purchase.

Emissions

The WEN DF623X 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, making it usable in forested areas.

The WEN DF623X versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN DF623X compare to dual fuel generators of similar power (between 4500 and 5500 W).

  • Regarding its weight, the WEN DF623X only weighs in at 132 pounds, which means it's one of the lighter dual fuel generators in the 4500-5500 rated wattage range. Regarding dry weight, one of the champions in the same power range is the Genmax GM6000iED, with a dry weight of only 117.9 lbs.
  • As far as autonomy is concerned, providing around 6 hours of runtime with a full tank at a 50% load, the DF623X falls into the low end in comparison with other dual fuel devices of a comparable power output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Pulsar G65BN, boasting with around 11.5 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 has an estimated fuel consumption of roughly 0.48 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If you wish to further improve in the area of fuel efficiency, the Westinghouse WGen5300DFv, which boasts with a gas consumption of only 0.43 GPH, may be the right generator for you.

Price comparison

As you can see from this interactive chart, when compared to other 4500-5500W dual fuel generators, the WEN DF623X is on the average side of the price range.

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