Description

Zoom on the WEN 56455i

In a nutshell, the WEN 56455i is a quiet and compact portable inverter generator mostly geared towards:

  • RV travellers looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events
  • Amateur DIY lovers
  • Homeowners in need of an emergency backup power for their essentials
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they 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

The WEN 56455i is powered by a 212 cc OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3500W as well as a peak wattage of 4500W. In addition, as it is parallel capable (parallel kit (opens in a new tab) not included), this power can be increased when linked to another similar or compatible unit.

The inverter generator features a simple traditional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 57 dBA (less noisy than rainfall).

With a full tank, the 56455i can operate for around 8.5 hours at 50% load (fuel consumption around 0.26 GPH), thanks to its fuel capacity of 2.2 gallons.

The 56455i generates a clean sine wave: providing <1.2% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel features the following 3 AC outlets:

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

It also sports 3 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle with which charging your batteries is made easy and two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this WEN generator is RV Ready.

Portability

The WEN 56455i is an inverter generator and has an encased design of the following dimensions: L23.2 x W18 x H20.1 in. Thus, it is more aesthetical than conventional, open frame products. The design follows the contemporary trends and is perfect for recreationally generating power.

The 99.2 lbs of the 56455i's dry weight enables you to use it anywhere you will ever need. Furthermore, once placed on the floor, effortless displacement is possible thanks to its set of 2 wheels and its folding handle.

Features

The 56455i's control panel

To help you monitor the 56455i's status and activity, its control panel is equipped with a digital data center, giving you information on the voltage, frequency, lifetime run hours, power output and fuel level.

In addition to this info, some light indicators allow you to instantly see if the oil level is too low, the generator is ready and the generator is on overload.

The fuel shutoff feature turns off the flow of fuel, allowing for the 56455i 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 an overload protection (circuit breaker) and an automatic low oil shut-off.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the WEN 56455i also comes with some accessories: funnel and tool kit are included.

Emissions

The WEN 56455i is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

The WEN 56455i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN 56455i compare to inverter generators of similar power (between 3000 and 4000 W).

  • Having a dry weight of 99.2 lbs, the WEN 56455i belongs in the expected weight range for inverter generators which produce 3000 to 4000 rated watts. If weight is your top priority, one of the champions in this power category is the Genmax GM3300i, weighing just 47.4 pounds.
  • With a lowest noise rating of 57 dBA, the inverter generator is one of the more quiet of the generators of similar type and power. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500DF, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • The 56455i, offering a run time of around 8.5 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse iGen4500DF, as it provides 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. With an estimated gasoline consumption of 0.26 GPH (gallon per hour) at 50% load, this inverter generator is among the more fuel efficient of the products in the above-mentioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.22 GPH, the Genmax GM3300i is a device you could look out for.
