In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.

Power & Run Time

With a 212 cc OHV 4-stroke engine, the WEN 56450iX operates on gasoline, providing 120V, with a running wattage of 3,500W and a starting wattage of 4,500W. Additionally, the parallel capability (parallel kit (opens in a new tab) not included) facilitates increasing of power output when linked to another similar or compatible unit, offering enhanced energy capacity and reliability for diverse requirements.

Enjoying a noise rating of 58 dBA (less noisy than rainfall), this inverter generator gets running thanks to a simple traditional pull-start mechanism.

Featuring a 2.2 gallons fuel tank, the 56450iX can provide power for around 8.5 hours at 50% load on a full tank (with fuel consumption averaging 0.26 gallons per hour).

The 56450iX generates a clean sine wave with <1.2% Total Harmonic Distortion (THD), ensuring minimal electrical noise and fluctuations. This feature makes it ideal for powering sensitive electronics, providing stable and reliable AC power through the outlets.


The control panel is equipped with the following 3 AC outlets:

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

Moreover, it presents 3 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle providing easy battery charging capabilities and two 5V USB ports (USB-A) with which charging of electronics like mobile phones and tablets is made convenient.

This WEN generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').


The WEN 56450iX's characteristic encased inverter generator design (L23.2 x W18 x H20.1 in) provides an aesthetic advantage and contributes to quieter operation compared to any ordinary, open frame product. This modern design aims to provide an ideal power solution to recreational users.

The 56450iX can be taken anywhere with you, thanks to its weight of 99.2 lbs. Moreover, its set of 2 wheels and its folding handle will allow you to easily shift it once it's on the ground.

The 56450iX's control panel

The control panel of the 56450iX includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the voltage, lifetime run hours, power output, frequency and fuel level.

In addition to this info, the device’s light indicators will display if the generator is on overload, the generator is ready and its oil levels are insufficient.

The fuel shutoff feature turns off the flow of fuel, allowing for the 56450iX 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.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to 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.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the WEN 56450iX also is packed along with the following accessories: tool kit and funnel. An official storage cover is also available, as a separate purchase.

The WEN 56450iX versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN 56450iX compare to inverter generators of similar power (between 3000 and 4000 W).

  • Weighing in at 99.2 lbs, the WEN 56450iX fits within the expected weight range for inverters producing 3000 to 4000 rated watts. If weight is an important consideration for you, the Pulsar PGD40iSCO stands out as one of the top contenders in this power category, with a dry weight of 46 pounds.
  • Since this inverter generator is rated for a lowest possible noise of 58 dBA, it can be considered as one of the more quiet of the products generating similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Westinghouse iGen4500DF, whose lowest noise levels reach just 52 dBA.
  • The 56450iX provides around 8.5 hours of runtime at a 50% load on a full tank, placing it within the average autonomy range among similar inverter generators. If runtime is a priority for you, the Westinghouse iGen4500DF stands out as one of the generators with the longest run time in its power range, providing around 15 hours of continuous use.
  • While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. With a fuel consumption rate around 0.26 GPH (gallon per hour) at 50% load, this inverter generator is one of the more fuel-efficient models within the aforementioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Pulsar PGD40iSCO, with a fuel consumption of 0.22 GPH could be in your good books.

Price comparison

As you can see from these interactive charts, when compared to other 3000-4000W inverter generators, the WEN 56450iX is on the average side of the price range.

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