Best Portable Generator Featured Image

A portable generator is the solution to all your power needs away from home. In addition to being a great power source for outdoor recreation, a portable generator can also be a lifesaver for unforeseen circumstances and emergency situations that could leave your home without power for days at a time.

By definition, a portable generator is “the combination of an electrical generator and an engine mounted together to form a single piece of equipment.” (1) This single piece of equipment is essential if your family’s camping needs depend on a reliable power source, or if you live in any area where a natural disaster could leave you without power for an extended period.

It can, however, be difficult to tell the difference between the many portable generators on the market today. So our list of the Top Ten Portable Generators will help you narrow things down by providing key specifications on the industry’s leading models. Also, be sure to read through our Buyer’s Guide for more information about choosing a portable generator that’s right for you.

Buyer’s Guide

The operating principle behind today’s portable generators was first introduced in 1831 by an English scientist named Michael Faraday (2). Faraday’s efforts led to electricity becoming available in many of today’s technologies.

When it comes to selecting from the many portable generators out there today, there are a few important characteristics to consider. To simplify things, this Buyer’s Guide will focus on power needs, portability, runtime, and outlets.

Power Needs

The first, and most obvious, consideration when selecting a portable generator is just how much power you’ll need. This requires thinking about how many devices or appliances you want to run off this one generator. It also requires you to know the wattage needed by each device as well as how much total wattage all devices and appliances will need.

Power needs will vary greatly depending on a number of factors. If you want a generator as a backup for your whole house, in the case of a power outage, you’ll need more wattage to power large appliances like a refrigerator and furnace.

But if you only want a generator that’s capable of charging everyone’s phones on your next car camping trip, your total wattage needs will be considerably less. It can often be helpful to make a list of all the devices you’ll want to power and then determine how much power it takes to start and run all of those devices.

Portability

Another important consideration is how easily you’ll be able to move around your generator. Of course, if your intention is to house the generator in your garage for emergency situations only, then portability is less of a priority.

If you plan on using your new generator for camping or other outdoor recreation pursuits, however, ease of transportation becomes much more important. Consider whether the generators you’re thinking of buying have wheels, as well as looking at how much they weigh, both empty and when they’re full of gasoline.

Runtime

Runtime is also important because you won’t always be able to accurately predict just how long you’ll need to rely on your generator as a power source. In most camping scenarios, it’ll be easier to regulate the amount of time you’ll need a generator. In this case, it might be limited to evening use for charging phones and running lights around the campground.

However, if you need a portable generator as a household backup or as a reliable power source on a construction site, you’ll likely be running it for hours at a time. In these scenarios, we recommend finding a portable generator that provides at least 10 hours of runtime.

Outlets

The final consideration when selecting a portable generator is the number and type of outlets each generator provides. The amount and specific type of outlets you’ll need will also depend on the devices and appliances you intend to power at once.

Unfortunately, not all devices and appliances use the same outlet types. This can become a critical consideration in the event of a home emergency. Make sure that the portable generator you select has enough outlets to supply power to all your essential appliances in the case of an emergency.

Frequently Asked Questions

Because not all portable generators are created equal, there is a lot to learn about using, storing, and maintaining them. Our Frequently Asked Questions section will provide answers to some of the most common questions about portable generators in order to help you make the best selection possible.

How many watts does a generator need to power a house?  

Most household appliances require between 3000 and 6500 watts. Homes with a smaller furnace and a city water connection can generally get by with a generator that provides between 3000 and 5000 watts. Homes with larger furnaces and a well pump, however, may require between 5000 and 6500 watts.

How many watts does it take to run a refrigerator on a generator?

Most appliances and devices need a certain starting wattage to power up and then less wattage to continue running. Common household refrigerators need around 2200 starting watts and then 700 running watts to continue operating efficiently.

Are there classifications of portable generators?

Generally, there are five common types of portable generator. They are solar/battery (great for camping and the least resource intensive), recreational inverter (great for RV enthusiasts and tailgaters), emergency (designed for emergencies but also worthy for camping or tailgating), semi-professional (popular amongst high-end homeowners and contractors), and professional (built for professionals that recognize that quality doesn’t come cheap).

What’s the best way to maintain a portable generator?

Because every model is different, the best techniques for maximizing the life of your portable generator will always be contained with the manufacturer’s operating, maintenance, and safety instructions.

Can you store a generator with gas in it?

While it’s not recommended, it is possible to store a gas-powered generator with a full fuel tank. However, most generators will require fuel stabilizer in order to do so safely. Fuel stabilizer prevents gum, varnish, rust, and corrosion from forming in a portable generator engine (3).

What’s the difference between rated watts and maximum (surge) watts?

Rated watts provide a measurement of the amount of power a portable generator can continuously produce. Maximum watts are the rating of power that a portable generator can produce for a short period of time. Maximum wattage is most need when starting a device or appliance (4).

What’s the difference between a standby generator and a portable generator?

When it comes to providing backup power for a home, portable generators are typically viewed as a temporary fix while standby generators are seen as more of a permanent solution. Portable generators need to be manually connected when needed, but also have the advantage of being used in situations other than only as a home backup power source.

Summary

Whichever generator you choose, it’s really important to become familiar with the best practices for generator safety (5). We hope that you’ve found the information in this article useful and we wish you the best of luck finding the portable generator that’s perfect for your needs.
