Westinghouse vs. DuroMax Portable Inverter Generator

It is common that sometimes you have to choose between two great generators for the money. At this point, you would be confused on how to proceed. The best way would be checking out the features of the generators to see which one would be great for your applications.

For this guide, we will focus on the Westinghouse iGen4500 and the DuroMax XP5500EH generator models. They are both affordable for the kind of power that they make. It is why people would want to see what more they offer in addition to the power.

Before we can get into their power and other features, let us see what you should consider when looking for the best portable generator.

What to Look For


When talking about a portable generator, these three are the most important considerations you will have to make so that you end up with a portable generator.

Look at its physical size. If you want a portable generator, then you need to get yourself a compact unit. The last thing you need is a bulky generator that would be hard to move around when you need to do so.

Some models would come with wheels to help with moving the generator. If the generator has wheels, then you know part of your portability is now solved.

Another consideration would be its weight. Since we are considering its portability, then go for a lightweight unit. Try to find a model in the range of 100 lbs. or below for portability.

When it is lightweight and it has wheels, its transportation would be easier.

Fuel Efficiency and Run Times

Generators mostly run on diesel or gas. It is then important that you understand their fuel efficiency.

Newer generators come with better engine technology aimed at improving the overall fuel efficiency. You should take the time to see what the manufacturer claims to be its fuel efficiency.

One way of understanding its fuel efficiency would be its run time. A model that comes with more runtime on a single tank of gas means that it has better fuel efficiency.

The runtime will determine how long the generator will run without you refueling it. It is easy to see that at this point you want more runtime and better fuel efficiency for a generator.

Noise Levels

A generator would easily make noise when it is running. The question is how much noise would a model be making?

If you know the noise level of the generator, then you would know if it is quiet for your application or not. There are some models that can be too loud for RV applications or home power backup with your neighbors around.

The noise level is measured in terms of decibels. Manufacturers will easily display this figure as they want you to know that their generator is the quietest.

Anything below 75dBA qualifies as a quiet generator. Yes, generators are not the quietest machines, but it is possible to get low noise models.

Manufacturers now also have low noise muffler designs. This means that you can experience low noise compared to some other old models in the same category.

Maximum Power

Still as part of getting a portable generator, look at the maximum power that it makes. The idea is to have a model that can handle your electrical load.

First, take an account of all the electrical load that you have in the house or RV before buying the generator.

Let us say that taking an account, your electrical load is 3000 watts at any given time. For such a load, go for a 4000-watt generator. Keep in mind that the 4000 watts should be the running watts and not the starting watts.

Power Quality

It might not seem as much, but you also have to consider the power quality that you are getting out of the portable generator.

New generators have the power inverters. These inverters are important for delivering smooth power to your appliances. The last thing you need is a generator that produces power that can fry your TV.

This stable and clean power is good for the sensitive electronics such as computers, TVs, radio, and more.

Look at the inverter technology that comes with the generator to see if it will be great for you.

Starting the Generator

Before you can choose any generator, always consider how easy or hard it is to start.

Gone are the days when you had to work your recoil start by pulling it several times to start the generator. Right now, there are models that have an electric start. All you have to do is press a button and your generator starts.

As much as they can have an electric start, they will also have the recoil start too as a backup method.

Safety Features

The safety features can vary from one model to another. The most common would be a low oil warning system. When the oil gets too low, the generator automatically shuts down to protect the engine from damage. Always look at this system to know when it is time to refill the oil.

Another common feature is the overload protection circuit. This circuit is important to keep your generator from overload and potentially damage its inverter. When it detects an overload, then the generator automatically shuts off for generator inverter protection.
