Westinghouse vs. WEN Portable Generator [What’s Better]

After experiencing several blackouts, that is when most people think of getting a backup method to power their homes.

There are several options available and the chances are people would go for a generator.

Depending on your electrical load, you might want to consider the Westinghouse WGen7500 or the WEN GN4500 generators. These two are worth every penny considering the power that you get out of them and the price at which they retail.

If you are going to have a great time using either of them, then it is important to learn more about their features. Before all that, let us see what to look for when choosing a generator.

What To Look For

EPA and CARB Compliance

Some might not consider them as being important, but always take note of such compliance certifications.

EPA stands for Environmental Protection Agency. It is mandated with making sure that such machines can remain low on emissions. If the generator is EPA compliant, then you know that the common pollutants are kept to a minimum.

The same goes for the CARB compliance certification too. CARB compliance is mandatory for California residents. Just know that CARB guidelines are stricter than the EPA. Having both certifications means that the generator is even better.

The Power of the Generator

This must be the most important consideration when choosing a generator. Power in this case we mean the rated output of the generator and not its engine-rated horsepower.

It is from the electrical load then you can know which generator would be ideal for you.

The first thing you need to do is list all the appliances which might need to get power from the generator. Once you total up their power ratings, then you will get the size of the generator that you need.

We recommend that you multiply the total by 1.25 as a way of oversizing the generator. This gives you more room to use more of the generator without straining it too much.

Let us say that the total power is around 2000 watts. When choosing a generator, go for one with around 3000 watts or more for the rated power output.

Engine Performance

If you do not have the best engine, then the generator might not last for long or provide you with the power that you want.

Looking at multiple generators in the market, we see that the majority are 4-cycle engines. This might be because such engines are less bulky and have a simple drive and lubrication mechanisms. They also generate impressive power for their size.

The powerful generators would have V-twin engines. Such engines can easily rotate at higher speeds so that you get more power at any time.

They are also characterized by being lighter and better balanced compared to other engine designs.

Other than the engine design, you also have to look at the engine displacement commonly referred to as cc.

Having a higher engine cc means it will be heavier. The misconception for most people is that higher cc means more power. That is not always the case.

Look at the overall power of the engine before deciding based on its cc figure.

The Starting System

The starting system always varies from one generator to another. When dealing with generators of output 3000 watts or lower, the starting mechanism is highly important.

You will get some models having a recoil start with others having an electric start. If you are going to choose a recoil start, then consider the number of pulls you have to make before the generator can start.

If you are likely to use the generator occasionally, then a recoil system is not such a bad choice. For those who might need to use it daily, then investing in an electric start should be the way to go.

Depending on the generator model, some might have an electric start as the main method and the recoil start as a backup. There are advanced generators that use key fobs to start and stop the generators.

You simply have to see which one would be ideal for your needs.

The Weight

You also have to consider the weight of the generator. For someone who wants something portable, then you need the weight to be as low as possible.

If a manufacturer makes a portable generator, then it would have features to make it adaptable to nomadic life as much as possible.

This is where some would have wheels for transport or open cages for carrying them around.

Always look at the generator weight to see which one would suit your needs if you ever want a portable generator.

The Noise Factor

When it comes to noise levels, that is also an important factor. The last thing you need is for the neighbors to find the generator too noisy.

The Fuel Use

Because of its overall power output, many people might be interested to know what kind of runtime they would get with the generator.

The generator can run for 11 hours on its 6.6-gallon fuel tank. This is enough time to power your appliances even if it means overnight.

The runtime is when the generator is running at 25% capacity. It is common for people to run their generators at this load capacity. If you increase the load, then the runtime will reduce too.

There is also a built-in fuel gauge. This will allow you to know when it is time to refuel the generator to keep it running smoothly.

WEN GN4500 RV Ready Portable Generator

WEN as a brand has been around since 1951. It is expected that this whole time it would make the best generators. Well, that is the case with the WEN GN4500 generator. It is one of the best to get for the money right now.

Other than being affordable, there are many other features you will like about the generator. Let us check them out below.

The Power

Like any other generator, a person would be interested in the amount of power that the generator makes. It is why we also have to see what this one makes.

The manufacturer rates it to have 4500 starting watts and 3600 running watts.

It is important that you distinguish between these two ratings of power. The running watts are what will be available continuously.

So, when using the generator, keep the electrical load lower than 3600 watts.

For its size and price, we find it is great with its power output. If you were going to get a Yamaha or Honda equivalent, it would probably cost twice or thrice.

So, it is a great deal for those who want an affordable and powerful generator.

Generator Runtime

This one comes with a runtime of 13 hours on its 4-gallon tank. This runtime is when the generator is running on a half load of its rated capacity.

When others need to run ¼ of their rated capacity to achieve such runtimes, this one runs half of its capacity.

It is easy to see that you would get more power delivery over an extended period before you can think of refueling the generator.

It is always nice to know what kind of power you are generating. It is why you will enjoy using the digital meter of this generator.

From the digital meter, you will get information such as the voltage, frequency, total runtime, and session runtime.

This is all the important information that you need to know about your generator. You never know when it might come in handy while using the generator over the years.

The Outlets

As part of making sure that you have an easy time using the generator, we find it has four standard 20A outlets for household use, transfer switch-ready outlet, and an RV-ready outlet too. These several outlets should make the generator a plug-and-play option for many.


As part of usability, we find that the generator is EPAIII and CARB compliant. This means that the emissions are low. You can use the generator for longer without worrying so much about its carbon footprint.

Another thing is that it comes with safety features such as an automatic voltage regulator, spark arrestor, and low oil shutdown. It should then be safe to use the generator on overall.


What are some of the safety features should you consider in a generator?

When buying a generator, consider safety features such as the low oil alert or shutdown feature. It is necessary to further protect the generator.

Another thing to keep in mind is overload protection. This will prevent the board of the generator from being damaged in case there is an overload.

Are electric starters better than recoil starters?

For many people, they should find electric starters better. This is because all you have to do is press a button and the generator easily starts.

If you have to get the recoil to start, make sure that it does not need too many pulls before the generator can start.

Is CARB and EPA compliance important?

These two certifications are important to always consider when choosing a generator. This is because they determine how much pollution the generator makes. If the generator has these two as part of its certifications, you are sure it is a low-emission generator.
