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 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 is powered by a 212 cc OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3600W as well as a peak wattage of 4500W.

With a noise rating of 65 dBA (just slightly more noisy than an office), the generator features a simple traditional pull-start mechanism.

The fuel capacity of 4 gallons allows the GN4500 to operate for around 13 hours at 50% load with a full tank (fuel consumption around 0.31 GPH).

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

This WEN generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The design of the WEN GN4500 is a typical, open frame, with the dimensions of L23.3 x W18 x H18.8 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.

The 97.9 lbs of the GN4500's dry weight enables you to use it anywhere you will ever need. Furthermore, the open frame of the generator further helps when holding and moving it to a different place.

Features

The GN4500's control panel

The GN4500's status and activity may be monitored conveniently via the control panel, as it features a convenient meter, which displays voltage, frequency and lifetime hours.

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

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

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

Emissions

The WEN GN4500 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use 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. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
  • Since the generator's noise is rated at 65 dBA, it has the roughly average expected noise for a device of similar power. For those who are looking for a less noisy device, we suggest the Cummins Onan P4500i. 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. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000X, boasting with around 16 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. With an estimated gasoline consumption of 0.31 GPH (gallon per hour) at 50% load, this 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 iGen4200, which has a fuel consumption of only 0.17 GPH and thus, is one of the most efficient devices in our database.

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.
