Best Powermate Generators Buying Guide

Why should you select a Powermate generator?

One of the main reasons Powermate is such a well-liked manufacturer for so many people is the fact that they are a company that has spent many years in the industry (over 40 years).

They have become well-known for specializing in power equipment that can power essential appliances, homes, and even RVs. 

As for their generators? Powermate ensures that all of their generators have been made to the highest standard,  thoroughly tested, and backed by a 3-year warranty.

Not only that, but Powermate is respected for their customer service quality, with many reviews online stating that any problems are handled swiftly and effectively.

Powermate even has multiple service centers dotted around the United States, where you can take the generator if you encounter any issues. 

If you choose to select a Powermate generator, you can also be confident that you’re going to enjoy easy maintenance.

Regardless of the model, they each come with a fuel gauge, low oil automatic shutoff, and wheels that will never go flat.

Each Powermate generator also features a control panel that is easy to understand thanks to its simple user interface, which ensures that operation will be easy. 

How to choose a generator

Before you go ahead and make a purchase, there are a few factors that you should make sure you take into consideration first - the first being how powerful you need your generator to be.

To determine how much power you require, follow our steps below:

Step #1: Decide what you need to power

First things first, make a list outlining all of the essential appliances and devices that you’re going to want to power.

If you’re purchasing a generator for use in the event of a power outage, you should ask yourself what you will need to power in the event that this happens. Do you only need to power lights?

Or perhaps you need to power all of your essential appliances? Some of the most powerful generators are able to power multiple devices at once, including high amperage appliances like a refrigerator. 

On the other hand, if you need a generator for use on a job site, you should make a clear list of all of the tools and additional appliances you will need to power throughout the day.

Besides tools, you should take into consideration whether or not you’ll need to power lights, or even a radio to keep you entertained.

As for camping trips, you’ll also want to think about how much outdoor cooking, entertainment, and heating appliances you and your family or friends may be using at once. 

Step #2: Determine the amperage of each appliance

This next step is really important. You’re going to want to make sure that your generator is going to be able to start up your appliances, and not just run it.

Every appliance you own will have what is known as a “starting wattage” which is the amount of wattage required to start an appliance with a motor.

Usually, the starting wattage is around three times greater than the wattage required to run it, so it’s paramount that the generator you choose can withstand this requirement. 

The easiest way to learn the starting wattage of the appliances you plan on powering is by referring to their owner manuals. Inside each manual, there should be a section that outlines all of the differing wattages, including the starting wattage and the running wattage.

If you have misplaced any of your owner manuals, we recommend contacting the manufacturer or checking to see if there is a version available to view online. 

Step #3 Calculate your overall power needs

To calculate your overall power needs, all you’ll need to do is carry out a simple two-part equation.

Firstly, add up all the running wattages for all the appliances you want to power simultaneously. The answer that you get will equal the total running watts that your generator needs to deliver to run all your equipment. 

After you have done this, then go ahead and add to that total the highest of the “starting wattages.

Once you have added those two figures together, you’ll then know how much power you’re going to need to both start and run all of your appliances and devices without any problems. 

Additional features to take into consideration:

  • Weather-resistance - If you plan on using your generator outdoors (for camping or using on a job site) you’ll want to ensure that your generator of choice offers some protection against the weather, especially of the control panel, as this area is most vulnerable to damage from rain and dirt. 
  • Multiple outlets - Another desirable feature is generators that offer multiple outlets. This will allow you to power multiple appliances simultaneously. 
  • Wheels - We recommend choosing a generator that features sturdy, rugged built-in wheels. This will allow you to easily pull and transport it from place to place without having to pick it up.
  • Muffler - Though not all generators offer a muffler, they are able to significantly reduce the sound of the engine noise. 

Frequently Asked Questions

Are Powermate generators good?

As you will have learned from our reviews above, Powermate creates well-crafted generators that are reliable, durable, and built to last.

In our opinion, though, the main reason as to why Powermate generators are so good is because they all come with various safety features, which is something that not all generators on the market offer.

What oil does a Powermate generator need?

Though there are many good quality oils available to buy, we think that any high-quality synthetic 5W-30 oil will be the best choice for your Powermate generator.

However, if you would like a recommendation, we think that Castrol 03084 EDGE 5W-30 is a failsafe choice.

Not only is it one of the best synthetic oils for generators, but it can also be used for car engines, which makes it more versatile than others.
