Description

The WEN Super Quiet 4500-Watt Inverter Generator produces clean energy free of voltage spikes and drops without all of the noise of a regular generator. Generate up to 4500 surge watts and 3500 rated watts of power. (source: WEN (opens in a new tab))

Zoom on the WEN 56450i

In summary, the WEN 56450i is a quiet and compact portable inverter generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The WEN 56450i's core is the 212 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3,500W and a peak wattage of 4,500W. Moreover, since it is parallel capable (parallel kit (opens in a new tab) not included), its power may be increased if linked to a second compatible unit.

With a noise rating of 58 dBA (less noisy than rainfall), the inverter generator features a simple traditional pull-start mechanism.

Thanks to a fuel capacity of 2.2 gallons, the 56450i can operate for around 8.5 hours at 50% load with a full tank (fuel consumption around 0.26 GPH).

The 56450i 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 provides the upcoming 3 AC outlets:

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

Furthermore, it has 3 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle allowing you to easily charge your batteries and two 5V USB ports (USB-A) with which charging of electronics like mobile phones and tablets is made convenient.

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

Portability

As the WEN 56450i is an inverter generator, its encased design (L23.2 x W18 x H20.1 in) offers more aesthetics than a conventional, open frame product. This type of design is the most modern and convenient way to recreationally generate power.

The 99.2 lbs of the 56450i's dry weight enables you to use it anywhere you will ever need. Moreover, its set of 2 wheels and its folding handle will allow you to effortlessly shift it once it's on the ground.

Features

The 56450i's control panel

One of the many 56450i's features is the data center, included in its control panel, which conveniently provides information on the power output, fuel level, frequency, lifetime run hours and voltage and thus, helps you monitor its activity and status.

In addition to this info, when its oil levels are insufficient, the generator is overloaded and the generator is ready, you will be informed by the featured light indicators.

The fuel shutoff feature turns off the flow of fuel, allowing for the 56450i 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 overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the WEN 56450i's package also includes these accessories: tool kit and funnel. An official storage cover is also available, as a separate purchase.

Emissions

The WEN 56450i 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 and therefore, can be used in forested areas.

The WEN 56450i versus other generators

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

  • Having a dry weight of 99.2 lbs, the WEN 56450i belongs in the expected weight range for inverter generators which produce 3000 to 4000 rated watts. If weight matters to you, one of the champions in this power range is the Pulsar PGD40iSCO with only 46 pounds.
  • With a lowest noise rating of 58 dBA, the inverter generator is one of the more quiet of the generators of similar type and 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.
  • As the 56450i offers around 8.5 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the inverter 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.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This inverter generator, with an estimated fuel consumption of just 0.26 GPH (gallon per hour) at 50% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Pulsar PGD40iSCO, which has a fuel consumption of only 0.22 GPH and thus, is one of the most efficient devices in our database.

Price comparison

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

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