Description

Zoom on the WEN DF623X

In a nutshell, the WEN DF623X is a portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners in need of an emergency backup power for their essentials

The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.

Power & Run Time

With its dual-fuel technology, the WEN DF623X delivers 120/240V, and offers power and flexibility. Running on gasoline, it boasts a running wattage of 5,000W and a peak wattage of 6,250W. When powered by propane, it delivers 4,500 running watts and 5,625 peak watts.

This generator offers two starting options: a traditional recoil pull-start mechanism and a convenient and efficient electric starter (battery included).

With a fuel capacity of 2.9 gallons, the DF623X can operate for around 6 hours at 50% load using gasoline (fuel consumption around 0.48 GPH), or for around 9.3 hours (on a 20 lbs tank - propane consumption around 0.51 GPH) using propane.

Considering its high Total Harmonic Distortion (THD) of less than 20%, it is not recommended to rely on the DF623X for powering sensitive electronic devices.

Outlets

The control panel features the upcoming 4 AC outlets:

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

Moreover, it presents 1 DC outlet: there's a 12V 10A (cigarette lighter style) receptacle providing easy battery charging capabilities.

This WEN generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'). In addition, thanks to its twist-lock L14-30R receptacle, the DF623X is transfer switch ready, facilitating easy hookup to your breaker box to provide backup power for your home during blackouts.

Portability

Measuring L26.1 x W23.4 x H22.1 in, the WEN DF623X showcases a classic open frame layout, guaranteeing stability and simple maintenance access to components, while facilitating air circulation. The device has been designed for tough environments and demanding outdoor use.

As the generator's weight is 132 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, the limited maneuverability is remedied with its wheel kit and its folding handle, facilitating convenient shifting once the generator is positioned on the ground.

Features

Panel of the WEN DF623X

The DF623X's control panel

For convenient monitoring of its status and activity, the control panel of the DF623X includes a convenient meter, showing voltage, frequency, and lifetime hours metrics.

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

In terms of security, the generator features an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during its 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.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the WEN DF623X, the following accessories are also included: oil, propane hose, tool kit and funnel. An official storage cover is also available, as a separate purchase.

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).

  • At 132 lbs in dry weight, the WEN DF623X fits well within the typical weight bracket for dual fuel generators producing 4500 to 5500 rated watts. Weight-conscious users may find the WEN DF5600X appealing, as it is one of the top contenders in this power range, weighing just 113 pounds.
  • As for its autonomy, the DF623X, with an autonomy of around 6 hours at a 50% load, is placed on the low end among the generators of its kind. 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 WEN DF5600X, with around 12.5 hours.
  • While run time matters, it's heavily influenced by the fuel tank's capacity. Hence, it's important to consider fuel efficiency alongside. Standing at an estimated 0.48 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the WEN DF5600X, which has an impressively low fuel consumption of 0.35 GPH.

Price comparison

As you can see from these interactive charts, 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.
