Westinghouse vs Yamaha Portable Generator: What is Better

Westinghouse Vs. Yamaha is an interesting comparison. This is because Westinghouse is known for being the budget generator that everyone needs.

On the other hand, Yamaha is known for its build quality, reliability, and so much more.

If you want more power and a reliable generator at an affordable price, then the Westinghouse WGen3600v unit is what you get. For those who are willing to spend more, then the Yamaha EF2000iSV2 is still a great choice.

Before we can look at the comparison between the two models, let us first look at the buying tips for a portable generator.

What to Look For

The Price

The generators will always vary from one brand to another. It is easy to get one brand selling its generators at a cheaper price when others sell them at a higher price.

This does not mean that the affordable generators would not be good in terms of performance. You need to understand the features that the generator has before you can decide if it is worth the money.

Look at the power output, runtime, clean power, efficiency, and a lot more then compare them to the price. If the price matches the generator features, then you should end up with a great generator by spending less sometimes.

Generator Size

So, what is the purpose of the generator? If you have hopes of taking it on road trips with you for your RV, then the size is an important consideration.

Depending on the power output and other features, the generators are likely to vary in terms of size. There are those that might be large but the power is low. That is also something to keep in mind.

You can find most lightweight generators being loved by campers for powering their basic electronics. So, consider the rated weight of the generator before making up your mind. Look at the overall size too before choosing one.

Depending on the model, some can be bulky and thus making them less portable. Some will even have wheels to aid with transportation. These are some of the considerations to make when looking for portability and size.

Noise Levels

Another top consideration should be the noise level. We all know that generators will always have noise. Even if the manufacturer claims that it is a silent generator, it will still produce some noise.

We recommend that you always take the time to look at the noise level numbers to see what kind of generator you are about to buy.

The last thing you need is a generator that is too noisy for your environment.

Those who want a quiet generator should consider going for those that produce noise levels of less than 74dBA. Anything over 85dBA would be hurting your hearing. It is why you need to aim for generators with lower numbers.

The Power

The overall power capacity of the generator would be measured in terms of watts. This will determine on overall what you can power with the generator.

If the generator has a higher wattage, then it means that you can operate more electronics on the generator.

You are likely to come across two types of power figures when looking at the specs sheet of a generator. The first one would be the running wattage and then there is the peak wattage.

The running wattage is described as the power that the generator will produce continuously. Under the normal running conditions of the generator, this will be the power that you get. As a result, you always have to keep the electrical load lower than this figure.

There is also the peak wattage. This is the maximum power that the generator can deliver. You are likely to get this power for a few seconds when it is starting up or when a large power draw happens.


Another thing to keep in mind is the durability. For most people, they want something that lasts them for at least a decade for a generator. That is possible considering most manufacturers are now making better generators.

Remember that durability goes in hand with the build quality and price. If you want to get a highly durable generator, then you must be willing to spend more to get the best generator.

Look at the materials used to make the generator. If the craftsmanship is also good, then the generator is going to last even longer.

Sometimes the manufacturer brand can be a good choice for those looking for the best generator. Go for the top brands because you are sure they will give you the best performance and durable generator for the money.

Fuel Use

The generators are likely to use the fuel differently. This is measured in terms of the runtime that the generator can manage on a single tank of fuel.

Most people would want a generator that can run for several hours without necessarily refueling. Look at the product description to learn more about its runtime.

There are models that can run for even 10 hours on a single tank of gas. However, this will also depend on the load capacity put on the generator. An increase in the load will reduce the generator runtime.

Most of the time, manufacturers would give the runtime based on the generator running at 25% capacity.

Maintenance Needs

Depending on the generator, some are likely to have more maintenance needs than others. For this reason, we recommend that you go for a model that does not need a lot of maintenance.

With less maintenance, then you can focus a lot more on enjoying the power from the generator rather than worrying it would break down easily.

What is the difference between the EF2000is and the EF2000isV2?

The EF2000isV2 is a redesigned model of the older EF2000is model. This means that it comes with a better controller board to help it run better than before. Also, the newer model can run for 13 minutes on the overload circuit. This means that it has more protection.

Is it possible to parallel the EF2000isV2 with the older EF2000is generator?

Yes. Yamaha makes it possible for you to connect even the different models together. Just make sure that you use the high-quality paralleling cable from Yamaha to ensure the best performance.

When you parallel them, keep in mind that the controller board will work like that of the older model. This means that the maximum AC output will not be up to 13 minutes before the generators trip.

What is the Westinghouse customer support like?

Based on many reviews about the Westinghouse generators, many people find their customer support to be good also. You are likely to have a great time getting all the information you need from the support team.

Can you run a generator for 24 hours?

A vast majority of the generator cannot run for 24 hours straight because of their fuel tanks. There are some that can do 15 hours on a tank of gas, but also that is when it is running on 25% capacity. If you can keep topping up the fuel, then you get yourself a generator that can run for 24 hours.

Is it good to use a fuel stabilizer in a generator?

Not many manufacturers recommend using a stabilizer in a generator. This is because the new engines are designed to work well with fuel. The fuel stabilizer might not increase the performance just as you had expected.
