Description

Zoom on the WEN 56455i

In short, the WEN 56455i is a quiet and compact portable inverter generator adequately designed for:

  • RV travellers looking for even more independence
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Amateur DIY lovers
  • Homeowners in need of an emergency backup power for their essentials
  • Camping and tailgating buffs looking to enhance their experience

In the forthcoming sections, you'll delve into its power characteristics, the various outlets it offers, its overall portability, and the additional features it boasts.

Power & Run Time

The WEN 56455i's design includes a gasoline-fueled 212 cc OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3,500W and also a peak wattage of 4,500W. Moreover, the parallel capability (parallel kit (opens in a new tab) not included) allows for increasing of power output when paired with another similar or compatible unit, providing increased energy capacity and reliability for diverse needs.

Enjoying a noise rating of 57 dBA (less noisy than a conversation at home), this inverter generator can be started thanks to a simple traditional pull-start mechanism, but also to a hassle-free and practical electric starter (battery included).

The 56455i boasts a fuel tank capable of holding 2.2 gallons, allowing it to run continuously for around 8.5 hours at 50% load (with fuel usage averaging around 0.26 gallons per hour).

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

Additionally, it features 3 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle making battery charging a breeze 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 meaning 'Travel Trailer'), this WEN generator is RV Ready, ready to power your recreational vehicle with ease.

Portability

The WEN 56455i is distinguished by its enclosed inverter generator design (L23.2 x W18 x H20.1 in), providing improved aesthetics and quieter performance compared to traditional, open frame units. This modern design aims to provide an ideal power solution to recreational users.

The 56455i can be taken anywhere with you, thanks to its weight of 99.2 lbs. Additionally, its set of 2 wheels and its folding handle enable easy movement of the generator once it's in place.

Features

The 56455i's control panel

One of the many 56455i's features is the digital data center, included in its control panel, which conveniently provides information on the power output, frequency, voltage, fuel level and lifetime run hours and thus, helps you monitor its activity and status.

In addition to this info, the light indicators show you if the generator is overloaded, the generator is ready and its oil levels are insufficient.

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.

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.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the WEN 56455i, the following accessories are also included: funnel and tool kit. An official storage cover is also available, as a separate purchase.

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).

  • At a weight of 99.2 pounds, the WEN 56455i places in the expected weight range of the inverter generators in the 3000-4000 rated wattage range. Weight-conscious users may find the Pulsar PGD40iSCO appealing, as it is one of the top contenders in this power range, weighing just 46 pounds.
  • Delivering a rated noise output as low as 57 dBA, this inverter generator is has a quieter operation that most units of similar type and power. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen5000DF with only 52 dBA.
  • With around 8.5 hours of runtime at a 50% load on a full tank, the 56455i is in line with the average autonomy range for inverter generators of comparable power. 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 Firman W03663OF, with around 18 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator is one of the more fuel-efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.26 GPH (gallon per hour) at 50% load. If you wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the Pulsar PGD40iSCO, which has an impressively low fuel consumption of 0.22 GPH.

Price comparison

As you can see from these interactive charts, when compared to other 3000-4000W inverter generators, the WEN 56455i is on the average side of the price range.

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