Westinghouse iGen4500 vs Champion 76533 Inverter Generator [All FAQs]

Power outages are one of the last things we want to happen. It can happen abruptly, turning a perfectly good day into a nightmare.

Your generator will be your lifeline if ever power goes out.

But what kind of generator do you need? Generators are not exactly one size fits all. Like all other products, there are generators that cater to different needs.

What to Look For?

Before selecting a generator, you have to know your needs first. You can’t just barge into a hardware store and buy the first model you see. You need to come in prepared, and here are a few things that you need to consider when looking for a generator.

Power Output

Generators differ in how much power they produce. With more power, the more devices it can run and the more convenient for you if there’s an outage.

However, you need to consider how much power you need too. You want to power your important appliances, but should you stop there?

Normally, 5000W would power enough of your major appliances to keep you running, and with more power to spare. However, even units with as low as 3000W can be more than enough for a small household.

To be sure, check how many watts your appliances need, and you can get an idea of how strong of a generator you are going to need.

Generator Type

With the power output covered,  it is also important to note that there are several types of generators. Each generator has its unique functions and features. Here are the main types to help you get an idea of which generator is best for you.

  • Standby Generator

A standby generator is the standard generator you would want if you’re not going anywhere. This device provides the best kind of protection as it is automatic. You never have to switch it on manually because it does everything automatically. Power outages won’t be an issue because you immediately regain power.

It can also run on almost any sort of fuel, depending on the model. Let it be propane or gasoline, you won’t have difficulty refueling it.

A useful feature is that it also tests itself automatically every week to see if it works fine just in case of power outages. Standby generators are great for emergencies and places that need power running continuously.

  • Portable Generator

The selling point of portable generators is that they are portable. This makes it great to take in and out of places and can be easily packed onto the back of a truck or a van. It also runs on gasoline or fuel so it is  cheap to fund.

The big difference that portable generators have is that they have sockets where home appliances can be plugged. In terms of appliances that can be powered, it can run almost just as well as a standby generator, the difference? Portability.

  • Inverter Generator

An inverter generator is one of the most efficient generators because it uses a rectifier to convert DC power to AC, which is generally more efficient in energy transfer, which an inverter generator does with ease. Inverter generators are also more efficient in the sense that they warm up.

Instead of starting at full capacity, they gradually increase depending on the need. This makes it more fuel-efficient and better!  These are also portable so think of these as more high-tech and efficient portable generators.

Startup Mechanism

If you’re investing money into a generator, make sure to add the extra dollars for convenience. Generators come with different startup methods such as electric, recoil, and remote startup. If you have the budget to spare, make sure to get one with up to an electric start for convenience.

Especially if you’re new to generators, having a convenient startup mechanism makes it easier to operate your generator and can save you time when you finally get the chance to use it.

Monitoring and Control Panels

If there is another must for your generator, it is a control panel. Control panels are useful because, ideally, it will have all the necessary information you need to know about the generator while it’s running.

This information can range from power output to fuel capacity so that you’ll never be guessing what’s going on with your generator. If any problems arise, some models have control panels that alert you of these issues.

Which is Better?

Now that we have laid down the basics of what to keep in mind when choosing generators, let’s take a look at these two models to see how they stack up against each other.

You might have some more questions regarding generators that haven’t been answered by the information above. Here is some more information that you might find useful

What type of fuel is best?

It depends on your needs. In terms of cost, gasoline is the cheapest and also the most common. People can opt to use propane as well for cleaner emissions and lower fuel costs in the long run, but propane-powered generators tend to have higher prices.

Diesel works fine as well, just make sure that it is compatible with your device so you won’t end up breaking it as diesel-powered generators are known to produce unstable power.

Can I keep my inverter generator inside the house?

Never keep your inverter generator running inside the house since it produces deadly smoke that can kill people inside the house. If you are storing it, that’s fine, but make sure it is in a cool and safe place away from children. Furthermore, make sure that the fuel tank is empty to prioritize safety.

 How long does a generator last?

A generator’s lifetime is parallel to how well you maintain it. The more attention you pay to its maintenance, the longer it will last. Some well-maintained generators even last for decades and more. If generators break down early, it’s almost always because of misuse and lack of maintenance.

What happens if I overload my generator?

Don’t attempt to make your generator supply more power than it can at the risk of breaking it due to overloading. Overloading happens when the wattage needed by the appliances plugged into your generator exceeds the running wattage. If this happens, then you’re risking your safety. To avoid this, try to look for models with overload protection.


The iGen4500 and Champion 76533 are equal in most respects, with each generator having a small edge in some areas.

The Champion 76533 holds the edge over the iGen4500 when it comes to wattage with 3800 running watts and 4750 starting watts compared to its counterpart’s 3700W and 4500W.

Furthermore, while they both have excellent fuel consumption, the Champion 76533 also beats the Westinghouse because of its dual-fuel feature that allows it to work using propane. If you don’t know, propane is more efficient to use than gas and has cleaner emissions.

Yes, the Westinghouse iGen4500 is a good generator, and we can’t blame you if you already bought it.

However, even with the Westinghouse’s minor power advantage, the Champion’s dual-fuel feature is too good to pass up, which is why the Champion 76533 is better than the Westinghouse iGen4500.
