Choosing the Best Portable Generator

What kind of criteria goes into making a list like this? You must consider the specifications (engine size, power output, weight, etc). Features are also important. There are other important details like design and aesthetics that play a part. It’s important to know what makes each of these generators different. It’s also important to understand what qualities are important for you and your goals.

Who Needs a Portable Generator?

Everyone. Well, not everyone. But most people could use the added security they provide. If you lose electricity in your home, a generator will allow to you run essential appliances, ensuring your family can continue to take care of itself.

A power outage will disable your air conditioning, water pumps, freezers and lighting. If the outage lasts for a few days, your home could become uninhabitable. But, with a powerful portable generator, you can keep running even heavy appliances like portable AC’s and space heaters.

Portable generators are also great tools for campers and outdoors lovers. They are a great tool for charging devices and powering things when no source of electricity is present.


Realistically, wattage should be one of the first or second things that you look for. Wattage is a measure of overall power output. The higher the wattage number, the more capable the generator is. Bigger appliances, like air conditioners and refrigerators, require a higher wattage amount. Generally speaking a wattage of around 2,000 is enough to handle mini-refrigerators, TVs, and space heaters. For larger appliances, you’ll need more wattage. On the other hand, small acts like charging a cell phone require much less wattage and can be accomplished with much smaller generators.


Every generator reviewed here is of course portable. However, there is a wide range of sizes for to choose from. Some can be carried with one hand and some may be best suited for being carried by two people. This is another instance where knowing exactly what you need and why you need it can come in handy. If you plan on traveling often, you should consider the size and weight of a generator. You should also look out for handles and wheels to assist in moving it. Generally speaking, as the wattage goes up, so does the weight.

Running Time

Running time refers to how long the generator can run for on one full tank of gas. This is another area where the generator’s purpose matters when determining how much you need. Many portable generators offer between 5 and 10 hours of running time. Some of the bigger models can go up to 20 hours on a single tank. If you’re buying a generator to also serve as your back-up at home, you might want the longer running time.

On The Job Site

Portable generators can also be found on construction sites. They are very useful on projects where electricity is unavailable or limited. They provide a consistent, reliable source of power for hand tools like drills, saws, etc. Essentially, any AC powered tool would work fine with a generator.

Portable Generator Buying Tips

Determine Your Power Needs

Before buying any type of generator, you need to determine just how much power you will need. Take inventory of every appliance and device that you will potentially be powering with your generator. In any case, you’ll only be able to power a few items at a time. Once you’ve figured out the items you’ll be powering most often, you can determine your generator requirements.

If you’re buying your portable generator as a backup in case of emergencies, this is especially important. You’ll likely be using it to power a microwave, mini-fridge, or space heater. To find the information regarding power consumption for your items, check their owners manual.

Even if you are using your portable generator for recreational fun, you still need ample power. It would be a big let down to finally make it into the woods for your camping trip only to find your generator is underpowered to run the big screen TV you brought along.

Fuel Types

Not all generators are built the same. Different types can run on quite a few different fuel sources. Each source has their own advantages and disadvantages.


Gas fueled portable generators are the most common compared to other fuel sources. Gas is less efficient than other fuel sources, but the plus side is availability. Gasoline is easily accessable. For this reason, gas fueled models are popular for emergency and recreational use alike. In most cases, fuel is never very far away.


Electric fueled generators use an electric starter, making them easier to operate than manual start models. The starter runs off a battery (usually lithium-ion) this is rechargable. These generators still use fuel, usually gas or propane.


The ‘clean’ burning propane is a popular fuel source for many generator owners. Like gasoline, it is easily accessible. It’s a consistent and efficient fuel source as well. Propane models run the gamut from small to very large. If propane is your preferred fuel source, you are sure to find a model you’ll like. Some models can accept more than one fuel source, usually propane and gasoline.


While rare, solar powered portable generators are growing in popularity. Some are built fully relying on solar power, and some models offer solar attachments. They do offer a few benefits. They are extremely quiet, and the fuel is as ‘clean’ as you can get. Another benefit is you don’t need any additional room for fuel storage. The downside is they can take a long time to charge and they’re not meant to power large appliances.


Diesel is more efficient than gasoline. Diesel engines also don’t have to worry about spark plugs or carburetors. On the other hand, diesel does not burn clean.

Top Features To Look Out For in a Moveable Generator

Sometimes a company will go the extra mile to provide the best products possible. This extra mile is all of the helpful and useful features that make some models better than the rest. Here are a few of the best and most useful features to look out for when choosing a portable generator.

Low Oil Shut Off

An engine without oil is a recipe for disaster. Let’s be honest, forgetting to check oil levels is a pretty common oversight. It happens to the best of us. But when it does happen, it can result in your engine seizing up and becoming useless. A low oil shut off mechanism cuts power to the machine when oil levels are low, preventing any catastrophic damage. Most models with this feature also have a light that illuminates to signal the mechanism is activated.


Each generator has a different configuration of outlets. They tend to have between two and three. Some models also have USB ports, which are good for charging phones or tables. Ideally they are GFCI outlets, which prevents electrocution from any water that comes in contact.

Electric Start

Here’s a feature that saves wear and tear on your arm and your machine. A convenient electric start button will activate your generator without having to yank on any pull cords.

Noise Reducing Frame

To be honest, generators can be loud. Even smaller, portable models. Luckily, there are ways to cut down on this noise to an extent. The quality of a generator’s frame and mounting hardware goes a long way towards reducing noise. Thick, dense metals that are strong are less likely to rattle around. The frame mounts, and feet, are often made using thick rubber. The rubber can minimize noise caused by vibrations.

Dual Fuel Capability

Most models run on a few popular fuel choices: gas, propane, diesel, electric. But a few models offer the ability to use more than one, most commonly gas and propane.

Spark Arrestor

The spark arrestor’s job is to catch any sparks or hot carbon and prevent it from doing any damage. The best portable generators surely have spark arrestors. They’re essential for outdoor or camping use, because an errant spark could easily case a forest fire.

Fuel Gauge

Keeping an eye on fuel levels is important and must be done. Having a gauge that can quickly and accurately present fuel levels is a nice convenience feature. This way, you’re never taken by surprise when fuel is low or empty.

Time/Hour Meter

A time meter records that amount of time your portable generator is running. This is important for maintenance first and foremost. A generator must be maintained and serviced properly to continue operating in peak condition.

Safety Considerations

Portable generators aren’t inherently dangerous, but they are fueled by substances that require respect and attention. It’s important to know the safety concerns that come with using, maintaing, and storing a generator.

Preventing Shocks or Electrocution

Never, ever connect your generator to a home outlet. It can feed back into you or your neighbors power lines, causing damage to the power lines and the homes they connect to. If you ever plan on connecting a generator to your own home’s circuit board, use a transfer switch to do so.

Before plugging anything into your generator, make sure it is running for a few minutes. Once it’s up and running you can plug your desired items in. Of course, be sure not to overload it (you won’t do this, since you’ve checked your item’s power requirements). When it’s time to turn your generator off, be sure to have unplugged everything prior to doing so.

Another thing: make sure your generator is grounded. Not being grounded is a main contributer to electric issues.

Following the above will go a long way to preventing any electrical issues that could harm you or your generator.

Fuel Safety

Portable generators run on common fuels. But these common fuels can be dangerous. Proper care must be taken when using, storing, and handling them. Propane can be explosive. Gasoline is very flammable. They should be treated with respect when dealing with them.

Do not overfill your generator. When fuel is heated, it expands. Allow a bit of room for expansion when filling up your tank. Overfilling can cause fuel to leak and come in contact with the hot engine. This is one reason you never want to add fuel while the generator is on or still warm from prior use. When filling up, make sure the unit is completely cool.

A portable generator can generate heat quickly and become very hot after a short period of time. The engine and parts surrounding it can easily burn your skin if you come in contact with them. It’s best to avoid moving or handling your generator until the unit has had time to cool. Furthermore, kids and pets should be kept at a safe distance away from a running generator to prevent an accidental burning.


Your portable generator relies on fuels that release nasty things into the air around them. More specifically, carbon monoxide aka the silent killer. Carbon monoxide is a deadly by product of burning gasoline, and usually goes undetected until it is too late. It’s very important that your generator has the room to ventilate properly. Proper ventilation will ensure the air you’re breathing is safe and not contaminated.

A major no-no is running your generator indoors. A garage or enclosed driveway are bad ideas even if you open every window possible. Fans and open doors will not do the trick either. Proper ventilation means outside. The further from walls and buildings, the better.

Usage and Storage

The way you use and store your portable generator is important in determining the longevity and usefulness that you receive from it.

As discussed above, generators are only to be used outside. And when they’re on and running, they need to have room to operate. Having a few feet of clearance on all sides goes a long way in preventing accidents. Make sure the surface is relatively level, and robust enough to support the unit.

Before and after using your generator, give it a quick inspection. There is maintenance to be aware of, like spark plugs, oil changes, etc. If something needs a repair, you can take note of it and fix it quickly. It could be a disaster if your unit is in need of repair for something that could easily have been spotted and fixed with routine maintenance. All generators come with manuals, and the manual can guide on what needs to be done at various usage intervals. Regular maintenance will keep your warranty intact and your unit working at maximum efficiency.

For storage, pick a dry and secure place. Protect the unit from the elements, and it should hold up fine. Follow the owners manual in regards to fuel draining, etc.


These are ‘portable’ generators, after all, but what does that mean?

A portable generator has to be easily stored, handled, and set up. That’s why they are so versatile. The smaller models have handles, and some can be carried with one hand. They offer ultimate portability and they don’t take up too much room. Medium sized models can usually be carried easily by the frame. The larger models usually come with wheels to make transporting easier. Portable generators are made for the average home-owner or recreational user. They are pretty simple in design. Their simple design paired with the efficient portability make them an extremely useful tool.


So, that’s a wrap for our complete buying guide to buying a portable generator. Do keep in mind all these factors before making your choice, as it’s not a small appliance that you can buy every other year.
