The compact size and portability of this generator make it the ideal tool for any emergency. In this Review, we are collating all the relevant information regarding Westinghouse 4500 generator, including the Best Features & Benefits, Specs, Pros and Cons, and User-rating as well.

Best Features & Benefits

Image Courtesy: DALL.E


It is mounted with a top-class 7.3 HP Westinghouse OHV(Over Head Valve) 4 Stroke engine with 224cc displacement. The engine is very powerful, and it will offer you a great runtime. This engine provides variable engine speed to produce enough power as per the altering demands.

It comes with a best-in-class Carburettor kit for high altitude usages where normal inverter generators might stop performing. (You can buy additional kits also.)

The Spark Plug used in the Westinghouse OHV engine is F7RTC(97109)/Torch E6RTC, which is best for easy ignition of the internal combustion engine-IC engine. (The spark plug is used to create a spark that ignites the fuel mixture in the engine, providing power to run the machine.)

The engine Oil Type used is SAE10W-30, and the oil capacity is 20.3oz or 0.60 L. Engine lubrication is done by the splash method by using engine oil.


The item is shipped without oil. So, don’t crank the engine before filling the lubricant oil. And, don’t use 2-stroke engine oils.

Power Output

This meticulous Westinghouse iGen4500 Inverter Generator can generate a maximum power of 3700 rated watts and 4500 peak watts, making it one of the most powerful generators in its class, and it can handle nearly any load.

(Peak watts and Rated watts means the amount of power the generator could produce for a short period or for a long run, respectively. )

It produces 120 volts ac stable power.


Fuel used is unleaded Gasoline of Octane value between 87–93. With this higher Octane value, it might be emitting lesser pollutants. (Westinghouse iGen has dual fuel generators as well. We will look into them in another review.)


Use only Clean, Unleaded Gasoline of Octane range 87-93. Don’t use E85/E15 fuel. Only up to 10% Ethanol is accepted

Fuel Tank

It has a very large, 3.4-gallon / 12.8L capacity fuel tank to save you repeated visits to the gas station.

Runtime & Fuel Efficiency

The runtime of this generator is pretty impressive. On a full fuel tank at 25% load, it will run for 18 hours. The fuel consumption rate is 0.188 GPH(Gallons Per Hour). It is considered one of the best fuel-efficient generators and will limit your gas station visits.

Economy Mode

For maximum fuel saving, you can turn the “Economy Mode” on this best fuel efficient inverter generator. This mode conserves fuel by automatically adjusting the engine speed to match the load. Running the generator in economy mode can save you money on operating costs, mainly by preventing you from repeated trips to the gas station.

Noise Level

iGen4500 Inverter Generator has a double-insulated acoustic enclosure, excellent lower-toned mufflers(Pulse-flo), and asymmetrical cooling fans equipped for better noise reduction.

So, the noise produced by the engine is very low. It only produces a 52 dBA noise level, which means it is one of the quietest generators in its class. (And it went miles ahead comparing the conventional generators in this regard.)

It’s perfect for any job site, camping trip, or tailgating party. It’s powerful and reliable, yet still super quiet. You can trust this generator to keep your things running smoothly by being less noisy.


This premium power solution has two 120V 20A 5–20R standard household outlets and one RV-ready TT-30R outlet that comes with a 120V 30A locking plug and cord. It will be helpful to connect your RV directly to this generator. 2 built-in USB ports are also available to charge your sensitive electronics like phones or tablets.

Total Harmonic Distortion or THD is a very important feature to consider while we use it for our home backup power. iGen 4500 has a THD of less than 3%. That means it generates more clean power suited for your sensitive electronics like Laptops, Tablets, Mobile phones, etc. The inverter technology used here is the key to this low THD.

Starting Systems

It has 3 different methods for starting. You can start it with a remote key fob, which is a wireless remote start for easy ignition. And is built with push-button electric start for easy starting, and, thirdly, you can do it with a usual recoil cord also.

You can operate the Key fob from a pretty distance of 100 m as per the Westinghouse iGen4500 Manual.

All 3 methods are very user-friendly and easy to use compared to the other inverter generators.

Parallel Capacity

You can double your power by parallel connecting the iGen4500 with another Westinghouse using a parallel cord (sold separately).
