Zoom on the WEN 56477i

To sum up, the WEN 56477i is a compact and lightweight portable inverter generator tailored for:

• RV travellers looking for even more independence
• People occasionally participating in sporting competitions, open-air performances and outdoor festivals
• Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.

Power & Run Time

The WEN 56477i's core is the 224 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 4,000W and a peak wattage of 4,800W. In addition, as it is parallel capable (parallel kit not included), this power can be increased when linked to another similar or compatible unit.

The inverter generator is rated for a noise of 62 dBA (just slightly more noisy than an office). Its starting mechanism is based on a classic hand-operated recoil starting mechanism.

Thanks to a fuel capacity of 1.9 gallon, the 56477i can operate for around 7 hours at 50% load with a full tank (fuel consumption around 0.27 GPH).

As the 56477i produces a clean sine wave, with a <1.2% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel features the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R)

120V 30A (TT-30R) receptacle

Moreover, it presents 3 DC outlets: there's a 12V 8A (cigarette lighter style) receptacle offering a convenient battery charging option and two 5V USB ports (USB-A) designed for hassle-free charging of various electronic devices such as smartphones and tablets, ensuring uninterrupted usage.

Featuring a TT-30R receptacle (TT for 'Travel Trailer'), this WEN generator is RV Ready, designed specifically for use with recreational vehicles.

Portability

The WEN 56477i is distinguished by its enclosed inverter generator design (L23.8 x W12.6 x H22.1 in), providing improved aesthetics and quieter performance compared to traditional, open frame units. The design follows the contemporary trends and is perfect for recreationally generating power.

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 telescopic handle, shifting the generator once it's placed is a breeze.

Features

The 56477i's control panel

Monitoring of the 56477i's status and activity is made possible by a digital data center, which provides information on the power output, fuel level, frequency, lifetime run hours and voltage 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 ready and the generator is on overload.

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 for its security measures, the device features a low fuel automatic shutdown, an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

Alongside the standard documentation and an owner's manual (opens in a new tab) for quick setup, the WEN 56477i is bundled with additional accessories: oil, funnel and tool kit.

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 weight, the WEN 56477i comes in at only 72.7 pounds, positioning itself as one of the lighter options among inverter generators spanning from 3500 to 4500 in rated wattage. If weight is a key factor for your needs, the WEN 56432iX is noteworthy for being one of the top contenders in this power range, with a dry weight of 52.9 pounds.
• The inverter generator's noise output, rated at 62 dBA, falls within the average range expected for devices in its type and power range. If noise is a concern for you, you could consider the Westinghouse iGen5000DF, which is one of the least noisy generators in its power range, rated at 52 dBA.
• Concerning its runtime, the 56477i provides around 7 hours at a 50% load, indicating that it falls on the lower side compared to other generators of its type and power range. For those prioritizing autonomy, the Westinghouse iGen5000DF could be considered, as it offers one of the longest run times among generators with similar power output, reaching 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 0.27 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 fuel consumption is your top priority, we suggest to check out the Westinghouse iGen5000DF, which has a fuel consumption of only 0.23 GPH and thus, is one of the most efficient devices in our database.
