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)

Zoom on the WEN GN4500

In summary, the WEN GN4500 is a compact portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from and any relevant emission compliance details.

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 3600W along with a peak wattage of 4500W.

Enjoying a noise rating of 65 dBA (just slightly more noisy than a normal conversation), this generator gets running thanks to a conventional pull-start mechanism.

With a full tank, the GN4500 can operate for around 13 hours at 50% load (fuel consumption around 0.31 GPH), thanks to its fuel capacity of 4 gallons.

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 stands for 'Travel Trailer'), this WEN generator is RV Ready.

Portability

The WEN GN4500 has the following dimensions: L23.3 x W18 x H18.8 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

The GN4500 can be taken anywhere with you, thanks to its weight of 97.9 lbs. Moreover, its open frame design makes it incredibly easy to grab the frame in order to change its location.

Features

The GN4500's control panel

The control panel of the GN4500 includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

With the basic documentation and an owner's manual, letting you start the generator quickly, the WEN GN4500 also comes with several accessories, including: oil and tool kit.

Emissions

The WEN GN4500 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

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).

  • Weight-wise, the WEN GN4500 has only 97.9 lbs, which renders it one of the lighter generators which produce 3500 to 4500 rated watts. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
  • This generator has a somewhat average expected noise for its power range, rated at 65 dBA. For those who are looking for a less noisy device, we suggest the Westinghouse iGen4500. With just 52 dBA, it is one of the most quiet devices in this power range.
  • As the GN4500 features an autonomy of around 13 hours at 50% load, it has a higher run time than an average generator of its power range. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000, as it provides around 16 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator can be considered as fuel efficient, due to its low estimated fuel consumption of only 0.31 GPH (gallon per hour) at 50% load, within the aforementioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W generators, the WEN GN4500 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.
