Description

Zoom on the Westinghouse iGen4500

In summary, the Westinghouse iGen4500 is a quiet and compact portable inverter 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 sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Camping and tailgating buffs looking to enhance their experience

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 Westinghouse iGen4500 in use

The Westinghouse iGen4500

The Westinghouse iGen4500 is powered by a 224 cc (7.3 hp) Westinghouse OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3700W as well as a peak wattage of 4500W. In addition, as it is parallel capable (parallel kit (opens in a new tab) not included), this power can be increased when linked to another similar or compatible unit.

The inverter generator features a simple traditional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 52 dBA (just slightly more noisy than a conversation at home). Moreover, to offer you even more convenience, the iGen4500 can also be remotely started (key fob included).

The iGen4500 can operate for up to 18 hours with a full tank (fuel consumption around 0.19 GPH), due to its fuel capacity of 3.4 gallons.

The iGen4500 generates a clean sine wave: providing <3% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel provides the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

It also sports 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.

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

Portability

The Westinghouse iGen4500's characteristic encased inverter generator design (L24.5 x W17.5 x H20 in), provides an esthetical advantage over any ordinary, open frame product. The design follows the contemporary trends and is perfect for recreationally generating power.

Since the generator weighs 104.7 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Nevertheless, thanks to its set of 2 wheels (⌀5.5") and its telecospic handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the Westinghouse iGen4500

The iGen4500's control panel

A digital data center, one of the features of the iGen4500's control panel, gives you information on the remaining run time, power output, lifetime run hours, fuel level and voltage, and thus, is helpful for the monitoring of its activity and status.

In addition to this info, a light indicator shows you if the generator is overloaded.

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

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Westinghouse iGen4500's package also includes these accessories: key fob, funnel, tool kit, battery charger and oil. A storage cover is also available, as a separate purchase.

Emissions

The Westinghouse iGen4500 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, making it usable in forested areas.

Product Videos

The Westinghouse iGen4500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Westinghouse iGen4500 compare to inverter generators of similar power (between 3500 and 4500 W).

  • Having a dry weight of 104.7 lbs, the Westinghouse iGen4500 belongs in the expected weight range for inverter generators which produce 3500 to 4500 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • Since this inverter generator is rated for a lowest possible noise of 52 dBA, it can be considered as one of the most quiet of the products generating similar power.
  • Given that the iGen4500 reaches an autonomy of up to 18 hours with a full tank and at 25% load, it is placed within the average autonomy range of similarly powerful inverter generators. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Firman W03661OF, which is able to run for up to 25 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This inverter generator reaches an estimated fuel consumption of 0.19 GPH (gallon per hour) at a 25% load, making it average, for the previously mentioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Champion 200988. With a fuel consumption of as little as 0.16 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W inverter generators, the Westinghouse iGen4500 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

About Westinghouse

The US based Westinghouse Outdoor Power Equipment is a legacy subsidiary of the Westinghouse Electric Corporation, founded in 1886. While the company has been acquired and merged into the American CBS, the Westinghouse name remains as the brand name for many of their electrical solutions, which stretch across the scale from power plants to portable generators. Portable generators – the main product of the Outdoor Power Equipment branch of Westinghouse – used to be manufactured by Westpro Power Systems, which was bought in 2016 by Midwest Equipment. Lawn equipment, such as trimmers and blowers, is also sold under the Westinghouse brand name. All of their products are designed in the US. However, several sources report that they are in many cases manufactured in China.

Changing oil for first time. What is the oil capacity of the igen4500? The key fob does not work. Do I need to program it? If so please tell me how. (Asked October 03, 2019)

The oil capacity is about 21 fl.oz. The key fob needs to be paired. To pair your remote to your iGen4500 press and hold the start button for 10 seconds the button will flash. At that point you can press either button on your remote and you have completed the pairing process.

Is a high altitude jet kit available for the unit? We need to use it at 8000 ft above sea level. (Asked June 08, 2020)

There is one, that is recommended up to 7000 ft. Its part number is 140573. Check this PDF file (opens in a new tab) to learn more about it.

    Very solid and well built generator, Westinghouse has addressed the choke cable issue, which wasn’t that big of a deal to begin with considering the price you pay for such an outstanding generator. I had purchased the high altitude kit for this and installed the jet myself without any problems, if you are willing to do it, it isn’t very difficult. The thing runs flawlessly, it’s quiet and has great features. Highly recommend this generator to anyone looking for this size and you won’t be disappointed.

    The igen4500 started without a hitch the first time. The next day It would not start until I manually adjusted the choke because one of the electric choke cables was disconnected. Once connected it starts all of the time. Too bad the factory does not apply a dab of silicone or something is not used to keep the cable in place. Runs real smooth and quiet and the smart panel comes in handy. Now I need to come with a light small clever cover or box to use the generator when it is raining.

    + PROS:
    • Value
    • Small Size vs Output
    • Easy to start
    • Fuel Efficient
    - CONS:
    • Had to connect electric choke cable
    • Oil draining is messy.

    I have had nothing but problems with this generator. I bought it to use with my RV. Fron the beginning, the run-time readout didn’t wotk and it kept tripping offline under light load.

    I finally took it in for warranty repairs and found out that inly the parts are civered under warranty, but, the labor is the big expense. The repair shop was not avke yo get the run- time indicator working after replacing parts and many hours of labor. They suggested that i “just look in the tank” to see how much fuel is left.

    I am now on an RV trip and can’t get the generator started.

    Spend the extra miney and buy a reliable generator. Don’t get stuck with a piece of junk that won’t start when you need it!

    + PROS:
    • Cheap
    - CONS:
    • POS. Not reliable.
