The Best Portable & Stationary Generators – Complete Buying Guide

The following is some very useful information when looking to purchase a new model.

What is a Portable Generator?

This refers to an electric generator model that meets certain requirements. A portable model can be described as one that needs nothing but fuel to work once its setup. The design of them allows the engine inside them to produce a steady flow of electric current as they are running.

A portable option also has several different power outlets built right into it. Do not be fooled by the term ‘portable’ here though. It does not always mean that a certain model is easy to take from place to place.

Whether it’s placed on a cart or on wheels a heavy portable option may still be a chore to move. What it does mean though is it’s a model that’s versatile. It also means it’s a unit that can be setup and work in little or no time at all.

Portable Generator Features

Here are some important features to focus on when shopping for a new one:

Power output

Power output on any model is expressed in watts. Doing the math is pretty simple here. The more watts a unit generates the more items it can power up.

Fuel type used

A good portable generator will usually run on one of three different types of fuel. They are gas, LP gas and natural gas. A unit that runs on LP gas will run longer than one that uses regular gas. Of course, natural gas supply is even better because it’s endless. A portable solar generator is hard to find but they are the cheapest to run and most green type of these devices.

Fuel capacity

This pertains only to LP gas and regular gas of course. It’s something you want to know for sure. That is because the bigger the tank capacity the longer a model can run without needing to be refilled.

Method of starting

If it’s raining or very cold out when you lose power hand cranking a generator will be no fun. That is why an electric ignition start is great to have. Large stationary options for your home will have an automatic starter and sense when you lose power and turn on.

Ready outlet types

Make sure you know what type of outlets your generator has built into it. That will let you know the extent of what you can run with it. Even a cheap generator will have a standard outlet, USB port and a DC plug. Be careful when buying a low cost model. It might not have the type of outlets you need.


As we just said not all portable models are really that portable. The ones that are truly portable will have some added features to help with that. They will typically be lighter, have oversized wheels and also have solid tubular frames built around them.

Generator Types & Styles

Here are some of the various types of generators described in more detail:

Portable generators

Just like the name says portable models are not meant to be used in just one place. That does not mean they are always easy to move. Oversize wheels and sturdy tubular frames help you move them easier.

Standby Generators

Standby options are large size units that stay in one place at a home or business. They come on automatically in the event of a power loss. Many are big enough to power large homes and workspaces.

RV Generators

RV generators are very similar to portable ones with one big exception. They have a special plug that RV’s use to hook into them.

By Fuel Type

Diesel Generator

Diesel options are the very large units you see outside of big buildings like grocery stores and hospitals. They run a long time on a tank of fuel and can power entire buildings.

Gas Generator

An affordable gas model is usually to the smaller side. These are best used when a small amount of power is only needed for a few hours. It’s the recommended type of generator when portability is a must.

Propane Generator

In comparison with gas models, propane fuel units run much longer. Customer reviews show these are starting to catch gas generators in popularity. They can be big or small size.

Electric Generator

Many people get a funny look on their face when they hear the words electric generator. It does not mean you have an electric powered generator to produce current. All generators can technically be called electric generators.

Solar Generators

Those people that like to choose green products are the ones that buy solar powered generators. When you look to purchase one of these be careful. They are not very budget friendly.

Inverter Generators or Conventional

More and more models that are being made are inverter type generators. That is because reviews by customers show they like their even current flow. A conventional generator’s energy flow fluctuates much more than those with an inverter.

By Size

The smallest generator models by far are those that run on gas. They are meant to be very portable and used for short periods of time.

Medium size options can be both portable and standby units. They can also be powered by different types of fuel. They have a wide variety of uses too.

Large size models are almost always home or business based standby units. They are so heavy they can’t be moved once in place. Most can run an entire home or work area.

Typical Uses of Generators

Here are some of the common reasons why you might want to buy such device:

Home backup power

One of the most frequent uses for these devices is simply as a backup home power source. These come in all shapes and sizes. Which one you choose depends on how many items you want to run at a time.

RV use

Portable models for RV use are usually rated under 4000 watts. They should also be easy to move because they do not stay in one place long.


Stereos, electric cookers and lights all need the power to run when you are tailgating. A good generator can be the life of the party.

Remote camps

Maybe you have a remote campsite or cabin that has no power. A generator will sure be nice to have here. It will enable you to have creature comforts even when far from home.

Medical equipment backup

Generators are a must-have piece of equipment if somebody has life-sustaining medical equipment that needs power at all times.

Jobsite power

One of the biggest uses of these devices is at work sites where no power has been hooked up yet.

Outdoor parties

Running extension cords all across your yard for a party is tedious and a tripping hazard. A few quiet models set up around your yard will help here.

Useful Generator Safety Tips

These devices can be dangerous to be around if they are not run with care. Here are a few important safety tips when using them:

  • Never pour gas into a hot generator. You also don’t want to change tanks on an LP gas generator when it’s still hot.
  • Do not try to move heavy models yourself. You can seriously hurt your back or injure a muscle. Better to call a friend to help just to be safe.
  • Never make electrical connections to a generator when it’s running. Make sure all cords are plugged in and connections made before starting it up.
  • Be extra careful when moving a hot generator. Still hot engines and exhaust ports can cause severe burns.
  • Never run any model unless it’s on very level ground. Generators placed on an angle may leak gas and become a fire hazard.
