Description

Zoom on the WEN 56477i

In a few words, the WEN 56477i is a compact and lightweight portable inverter generator perfectly suited for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in outdoor fairs, festivals or events
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Camping and tailgating hobbyists looking for a portable power source

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

WEN 56477i runs on gasoline, powered by a 224 cc OHV 4-stroke engine, delivering 120V, boasting a running wattage of 4,000W alongside a starting wattage of 4,800W. In addition, the parallel capability (parallel kit not included) empowers increasing of power output when linked to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.

The inverter generator is rated for a noise of 62 dBA (just slightly more noisy than background music). Its starting mechanism is based on a standard recoil pull-rope starting mechanism.

Featuring a 1.9 gallon fuel tank, the 56477i can provide power for around 7 hours at 50% load on a full tank (with fuel consumption averaging 0.27 gallons per hour).

The 56477i ensures a clean sine wave output, boasting <1.2% Total Harmonic Distortion (THD) to protect your sensitive electronics when connected to its AC outlets.

Outlets

The control panel includes the following 5 AC outlets:

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

Furthermore, it showcases 3 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle with which you may charge your batteries with ease and two 5V USB ports (USB-A) ensuring convenient charging of devices like mobile phones and tablets, for connectivity on the go.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this WEN generator is RV Ready, making it ideal for powering recreational vehicles.

Portability

Since the WEN 56477i is an inverter generator, its closed design (L23.8 x W12.6 x H22.1 in) not only provides an aesthetic advantage but also contributes to reduced noise levels compared to conventional, open frame devices. The featured design follows the latest trends and is ideal for easy and recreational use.

With a dry weight of 72.7 lbs, the 56477i is manageable, ensuring it can accompany you wherever you need power. Furthermore, thanks to its set of 2 wheels and its telecospic handle, shifting the generator once it's placed is a breeze.

Features

Panel of the WEN 56477i

The 56477i's control panel

The control panel of the 56477i includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the lifetime run hours, power output, voltage, fuel level and frequency.

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

The fuel shutoff feature turns off the flow of fuel, allowing for the 56477i 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 automatic low oil shut-off, an overload protection (circuit breaker) and a low fuel automatic shutdown.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the WEN 56477i also is packed along with the following accessories: oil, tool kit and funnel.

The WEN 56477i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN 56477i compare to inverter generators of similar power (between 3500 and 4500 W).

  • Regarding its weight, the WEN 56477i only weighs in at 72.7 pounds, which means it's one of the lighter inverter generators in the 3500-4500 rated wattage range. if you wish to prioritize weight, the Genmax GM4600iAEFIC is one of the top contenders in its power category, weighing only 58.4 pounds.
  • The inverter generator can be considered average in its noise for its type and power category, as it is rated at 62 dBA. If noise emissions are one of your priorities, you may want to take a look at the Westinghouse iGen4500DF. It's one of the quietest options among generators of similar power, rated at 52 dBA.
  • Autonomy-wise, with around 7 hours on a full tank at a 50% load, the 56477i is on the low end when compared to other inverter generators of a similar power output. 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.
  • Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. Among generators of similar power, this inverter generator stands out with a better fuel efficiency than most, with consumption rates around 0.27 GPH (gallon per hour) at 50% load. If you're placing a high priority on fuel consumption, the Westinghouse iGen4500DF, with a low fuel consumption rate of 0.23 GPH, could be an option to consider.

Price comparison

As you can see from these interactive charts, when compared to other 3500-4500W inverter generators, the WEN 56477i is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
