Here are some of the best advantages the Westinghouse iGen4500 offers:

Delivers Unmatched Power

Inverter generators are the go-to for RVs. Unfortunately, many models aren’t powerful enough for your energy needs.

Luckily, this portable inverter generator offers unmatched power. It can deliver a whopping 4,500 surge watts and 3,700 running watts. The convenient ports (including the TT-30R RV-ready outlet) will keep all of your devices running.

Portable Inverter Generator

You might think that such power would make the unit clunky. However, you’ll be pleased to hear that this is a great portable inverter generator.

The unit features a compact design with wheels. It also has a retractable handle, making it easy to drag the unit behind you. Thanks to the never-flat tires, it can survive pretty much any terrain. If you need to carry the unit, you can take advantage of the two ergonomic carrying handles.

Large Fuel Tank

The nearly 4-gallon fuel tank is bigger than what most inverter generators have. But, this is a plus as it runs for longer. It has a 12-hour run time on 50% load. If you want an even longer run time, set it to 25% load for an 18-hour run time.

Efficient Engine

Aside from the large fuel tank, this generator also has long run times thanks to its efficient engine. It uses variable engine speed to produce just the right amount of power.

If you want, you can add an automatic voltage regulation device. The device will provide maximum fuel efficiency by controlling wattage output. This is also useful if you need to limit the amount of power going to, say, mobile devices that require a certain wattage.

Even if you don’t use an automatic voltage regulator, this generator will save you repeated trips to the gas station.

Conveniently Built

This is one of the most user-friendly inverter generators out there. It is conveniently built with a push-button electric start right on the control panel.

Remote Start

You can also start the unit remotely with an electric remote key fob—the electric remote works from over 100 yards away. The combination of push electric start and wireless remote start makes operation flexible and easy.

LED Data Center

The LED display on the control panel is a lifesaver. The automatic rotating digital display is ready and shows crucial information such as:

  • Wattage output
  • Fuel level
  • Remaining run time
  • When it’s time to perform maintenance
  • Low oil warnings

So, as the generator provides stable power, the LED display shows you these important stats. Even better is that the display is easy to read (even when visibility isn’t great).

Produces Clean Electricity

As we already mentioned, the Westinghouse iGen4500 produces clean electricity. This is good for a couple of reasons.

For one, sensitive electronics like LCD plasma televisions require clean, stable power to charge safely. This generator has a total harmonic distortion that’s less than 3%, which will protect your phones, laptops, etc.

The clean electricity this generator uses also makes it EPA, USFS, and CARB compliant. So, you can sleep soundly knowing you won’t be violating any regulations. This generator is legal to own in all 50 states.

It’s Super Quiet

One of the main perks of inverter generators? They aren’t as loud as their standard counterparts.

You’ll be glad to hear that the iGen 4500 is super quiet. This is impressive, considering that it can produce 4500 peak watts and 3700 rated watts.

The low noise level of 52 dB is perfect for camping or other outdoor activities. For one, it won’t throw a wrench in your sleep schedule. It will also help you be respectful to your neighbors. And, best of all, it won’t disturb the natural environment.

The Westinghouse iGen4500 is great. However, it has a couple of cons that are worth mentioning.

It’s Heavy

People love inverter generators because they tend to be lightweight. However, this is where the Westinghouse iGen 4500 falls short.

It weighs almost 100 pounds. This is largely due to its big fuel tank and battery to power the wireless remote. You can pull the unit with its suitcase-style handle, making it convenient. But, if you need to carry it, it won’t be easy on your own. Even with the extendable suitcase-style handle, comfortable lifting requires two people.

If you foresee this being a problem, you might want to go with another generator. A comparable model (like the iGen2500) has a smaller fuel tank to save space and weight. It features a lightweight, compact design that makes it easier for one person to carry.

It Isn’t Parallel Capable

Most inverter generators are parallel capable. With this in mind, it’s a bit surprising that the iGen4500 is not.

This means that you cannot connect it with another generator to increase power output. It’s not a huge deal, considering how powerful the iGen4500 already is. It would be nice to see this feature as it would provide even more wattage to your RV.

It Only Runs on Gas

The iGen4500 is a gas-powered inverter generator. It exclusively uses gasoline to operate.

There’s nothing inherently wrong with this engine style. However, some users prefer dual-fuel generators.

Dual-fuel generators use both gasoline and propane to operate. It switches between the two fuels to maximize efficiency. This results in a more eco-friendly unit.

If this is something you’re looking for in a generator, consider a model like the iGen4500DF. It is very similar to the standard iGen4500, except that it uses a mixture of gasoline and propane.

Customer Reviews

Wondering what users are saying about the Westinghouse iGen4500?

After browsing reviews online, we can say that feedback is mostly positive. The generator has nearly 1,000 verified reviews on Amazon that result in a near 5-star rating. Other review sites have similar ratings.

Overall, the consensus is that the iGen4500 is the ideal outdoor power equipment. People use it for their RVs, camping trips, and other outdoor events. They love that it is powerful, portable, and offers easy ignition. At less than 3% THD, the generator is also great for its clean energy output.

Additionally, users like that the LED screen is legible and warns them about low oil, running time, etc. They also rave about the key fob remote start as most inverter generators lack electric start.

Common complaints include that the unit is too heavy and that it isn’t parallel capable. People also warn that it may contain minimum residual oil on arrival. But, these complaints don’t take away from the convenience this generator offers.

Alternatives to the iGen4500

Not sold on the iGen4500? Two comparable models are the iGen2500 and the iGen4500DF from Westinghouse.

The iGen2500 is essentially the smaller version of the iGen4500. It doesn’t offer nearly as much power (2,500 surge watts and 2,200 running watts). However, it’s more compact and easier to transport.

If you want to keep the same power output as the iGen4500, go with the iGen4500DF. This generator is very similar except that it has a dual-fuel engine.


Are Westinghouse generators quiet?

It depends on which Westinghouse generator you purchase. Generally, an inverter generator is quieter than a standard generator. This is because they tend to be smaller and have a lower output. The iGen4500, for instance, has a noise level of 52 dB. This is fairly quiet and won’t disturb your peaceful surroundings.

So, if you want a quiet Westinghouse generator, be sure to get an inverter generator. Westinghouse’s standard generators are louder. This is to be expected and may be worth the noise as it produces more power.

Where are Westinghouse generators built?

Westinghouse manufactures its generators in its facility in Columbus, Ohio. The company has been making portable generators since 2011. It uses high-quality materials and techniques to produce each unit. And, the craftsmanship is backed by more than one hundred years of experience.

If you want a high-quality generator made in the USA, consider a product like the iGen4500. It is well-designed and built to last. And, with your purchase, you’ll be supporting an American manufacturer and the national economy.

Are Westinghouse generators any good?

Westinghouse produces some of the best generators on the market. They are well-built, powerful, and energy-efficient. Even better is that there’s bound to be one that fits your unique needs. Westinghouse has traditional generators, generators that run on solar energy, etc. Where the manufacturer truly shines, however, is with its inverter generators like the iGen4500.

This gas-powered portable inverter generator is just what your RV needs. It has a convenient electric start and is easy to transport. Most importantly, it delivers the wattage you need to power your devices.

Verdict: Should You Buy the Westinghouse iGen4500 Inverter Generator?
