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 outdoor fairs, festivals or events
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Camping and tailgating buffs looking to enhance their experience

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 56450i houses a 212 cc OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3500W along with a peak wattage of 4500W. 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.

The inverter generator features a conventional pull-start mechanism. It is rated for a noise of 58 dBA (less noisy than rainfall).

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

Sensitive electronics can be safely plugged in the AC outlets, as the 56450i produces a clean sine wave, with a <1.2% Total Harmonic Disruption (THD).

Outlets

The control panel features the upcoming 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 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.

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

Portability

The WEN 56450i's characteristic encased inverter generator design (L23.2 x W18 x H20.1 in), provides an esthetical advantage over any ordinary, open frame product. The design follows the contemporary trends and is perfect for recreationally generating power.

The 56450i's dry weight of 99.2 lbs lets you use its power anywhere needed. Moreover, once it’s on the ground, its set of 2 wheels and its folding handle will allow you to shift it without effort.

Features

The 56450i's control panel

Monitoring of the 56450i's status and activity is made possible by a digital data center, which provides information on the voltage, frequency, lifetime run hours and fuel level and is one of the features of its control panel.

In addition to this info, the light indicators show you if the oil level is too low, the generator is overloaded and the generator is ready.

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.

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.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the WEN 56450i also comes with several accessories, including: 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, which makes it suitable for use 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).

  • As its weight is 99.2 pounds, the WEN 56450i falls in the expected weight range of the inverters in the 3000-4000 rated wattage category. In terms of weight, one of the champions in their power range is the Genmax GM3300i, standing at just 47.4 lbs.
  • With a lowest possible noise of 58 dBA, this inverter generator places itself amongst the more quiet of the products delivering similar power. If noise emissions are one of your priorities, you may be interested in the Cummins Onan P4500i, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • Autonomy-wise, with around 8.5 hours on a full tank at a 50% load, the 56450i is on the low end when compared to other inverter generators of a similar power output. 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 Cummins Onan P4500i, with around 15 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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.

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.
