Description
Zoom on the WEN 56475
In a nutshell, the WEN 56475 is a compact portable generator mostly geared towards:
- RV travellers looking for even more independence
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.
Power & Run Time
Featuring a 223 cc WEN OHV 4-stroke engine, the WEN 56475 operates using gasoline, providing 120V, with a running wattage of 3,750W and a starting wattage of 4,750W.
Operating with a noise rating of 67 dBA (less noisy than an office), this generator offers two starting options: a classic hand-operated recoil starting mechanism and a no-fuss and convenient electric starter (battery included).
The 56475 boasts a fuel tank capable of holding 4 gallons, allowing it to run continuously for around 10 hours at 50% load (with fuel usage averaging around 0.4 gallons per hour).
Outlets
The control panel features the upcoming 4 AC outlets:
With its TT-30R receptacle (TT standing for 'Travel Trailer'), this WEN generator is RV Ready, perfectly suited for powering recreational vehicles.
Portability
With its L23.2 x W17.6 x H18 in dimensions, the open frame structure of the WEN 56475 provides stability, simplified maintenance access to components, and better air cooling than enclosed units. The featured design is ideal for the outdoors and all tough environments.
While weighing 116 lbs, the generator is classified as 'portable,' indicating its mobility, albeit its heftiness may limit portability in specific situations. However, its challenging mobility is solved by its wheel kit (⌀8") and its folding handle, which will ease its displacement, once it is on the floor.
Features
Monitoring of the 56475's status and activity is made possible by a digital data center, which provides information on the lifetime run hours and is one of the features of its control panel.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
As far as security is concerned, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during use.
In addition to the traditional documentation and an owner's manual (opens in a new tab) to help you get started promptly, the WEN 56475 also includes several accessories: oil and funnel. An official storage cover is also available, as a separate purchase.

The WEN 56475 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the WEN 56475 compare to generators of similar power (between 3500 and 4500 W).
- At 116 lbs dry, the WEN 56475 is consistent with the standard weight profile for devices ranging from 3500 to 4500 rated watts. If weight matters to you, one of the champions in this power range is the WEN 56432iX with only 52.9 pounds.
- With noise emissions rated as low as 67 dBA, this generator falls within the typical noise range expected for devices of similar power. If noise level is one your key decisive factors, you may find the Westinghouse iGen5000DF appealing. It's rated at 52 dBA, making it one of the quietest generators in its power range.
- At a 50% load, the 56475's around 10 hours of runtime on a full tank fall within the average autonomy range for similarly powerful generators. If extended autonomy is what matters most to you, the Firman W03663OF could be an excellent choice, offering one of the longest run times among units in its power category, reaching around 18 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. Compared to similar devices, this generator is less fuel-efficient than most: it burns around 0.4 gallons of gasoline per hour at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen5000DF. With a fuel consumption of as little as 0.23 GPH, it is one of the most efficient generators currently on the market.
Price comparison
As you can see from these interactive charts, when compared to other 3500-4500W generators, the WEN 56475 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.
The bottom line
- Inexpensive
- RV Ready
- Electric start
- Decent weight (116 lbs)
- Acceptable noise (67 dBA)
- Decent run time
- No remote start
- Low fuel efficiency
