This unit might be hard to find. For your convenience, we gathered the following alternatives with similar specs:

Description

The powerful 212cc OHV 4-stroke engine generates up to 4500 surge watts and 3600 running watts of reliable power. The digital data meter displays the voltage, frequency, session runtime, and total runtime, making it easier to schedule routine maintenance and monitor the generator’s output. This generator is also compatible with the WEN GNA410 Wheel and Handle Kit for easy transportation and storage (sold separately). (source: WEN (opens in a new tab))

Zoom on the WEN GN4500

In a nutshell, the WEN GN4500 is a compact portable generator mostly geared towards:

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

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

The WEN GN4500 houses a 212 cc OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3,600W along with a peak wattage of 4,500W.

Operating at a noise rating of 65 dBA (just slightly more noisy than an office), this generator starts up with a classic hand-operated recoil starting mechanism.

The GN4500's fuel tank, with a capacity of 4 gallons, supports uninterrupted operation for around 13 hours at 50% load when fully fueled (fuel consumption at an estimated 0.31 gallons per hour).

Outlets

The control panel provides the upcoming 6 AC outlets:

Two Duplexes 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120V 30A (TT-30R) receptacle

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

Measuring L23.3 x W18 x H18.8 in, the WEN GN4500 showcases a classic open frame layout, guaranteeing stability and simple maintenance access to components, while facilitating air circulation. This type of design is ideal for tough environments and heavy outdoor use.

With a dry weight of 97.9 lbs, the GN4500 is convenient, ensuring it can be taken wherever power is needed. Moreover, the open frame structure of this generator makes it easy to grab and relocate.

The GN4500's control panel

The GN4500 and its control panel include a convenient meter, showing voltage, frequency, and lifetime hours metrics. This feature comes handy when monitoring its status and activity.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

From a security standpoint, the generator is furnished with an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during operation.

Alongside the standard documentation and an owner's manual (opens in a new tab) for quick setup, the WEN GN4500 is bundled with additional accessories: tool kit and oil.

The WEN GN4500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the WEN GN4500 compare to generators of similar power (between 3500 and 4500 W).

  • Regarding its weight, the WEN GN4500 only weighs in at 97.9 pounds, which means it's one of the lighter generators in the 3500-4500 rated wattage range. Weight-conscious users may find the Genmax GM4600iAEFIC appealing, as it is one of the top contenders in this power range, weighing just 58.4 pounds.
  • With noise emissions rated as low as 65 dBA, this generator falls within the typical noise range expected for devices of similar power. For those who are looking for a less noisy device, we suggest the Westinghouse iGen5000DF. With just 52 dBA, it is one of the most quiet devices in this power range.
  • In terms of run time, the GN4500 surpasses similarly powerful devices, boasting one of the higher run times at around 13 hours. If runtime is a priority for you, the Predator 4375 stands out as one of the generators with the longest run time in its power range, providing around 16 hours of continuous use.
  • Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. This generator provides better fuel efficiency than most others in its wattage range, consuming approximately 0.31 GPH (gallon per hour) at 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.23 GPH, the Westinghouse iGen5000DF is a device you could look out for.

    I essentially agree with you on strengths and weaknesses, at least for the plus/minus 4 hours it ran. It starts and runs and it appears there is at least power for charging the RV batteries, but nothing AC works at all. Hopefully, it’s not a serious problem.

    + PROS:
    • It worked well for some hours.
    - CONS:
    • It quit working, at least in regard to electrical output.
