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

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • 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's core is the 212 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3,600W and a peak wattage of 4,500W.

The generator is rated for a noise of 65 dBA (just slightly more noisy than background music). Its starting mechanism is based on a conventional pull-start mechanism.

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

Outlets

The control panel features the following 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 dimensions of the WEN GN4500, which are L23.3 x W18 x H18.8 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

The GN4500 can be taken anywhere with you, thanks to its weight of 97.9 lbs. In addition, it is even easier to grab and move the generator around thanks to its open frame design.

The GN4500's control panel

The GN4500's control center features a convenient meter showing you voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

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.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the WEN GN4500, the following accessories are also included: 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, making it usable 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. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
  • The generator can be considered average in its noise for its power category, as it is rated at 65 dBA. If you are concerned with noise, check out the Westinghouse iGen4500DF, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • The GN4500 provides a higher run time than similarly powerful devices, reaching around 13 hours at 50% load. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 4375, reaching around 16 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. At an estimated fuel consumption of 0.31 GPH (gallon per hour) at 50% load, this generator is a rather fuel efficient one within its wattage category. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.23 GPH, the Westinghouse iGen4500DF is a device you could 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.

    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.
