There are many reasons why you might find yourself caught without a power supply that could result in a real inconvenience. For this reason, a portable generator can be invaluable as it means that you will never find yourself without power ever again.

Though the designs vary quite considerably depending on how much power and what level of portability they offer, the aim is to make sure that you have a reliable power supply whenever and wherever you need it.

With so many different products on the market, it can be a headache trying to find the right one. That is why we have compiled a list to help you find the top portable generator for your needs.

What is the best portable generator?

To understand just why there are so many portable generators on the market today, you only need to take a moment to consider the huge range of reasons people need them. Portable generators are used for backup home and mobile home power supply, by tradesmen in buildings where the electricity has been turned off, racing teams who need to power their equipment and even farmers to power electric fences. There are literally thousands of reasons why people use portable generators and that is why they vary so much in design.

Main differences between portable generators


The most obvious difference between portable generators is how portable they are designed to be. For a generator to be considered as being portable, it only needs to be able to be moved by a single person from place to place.

Many of the larger generators are too large to be carried or even to be picked up for long, and rely on wheels to be moved around. Some generators, on the other hand, are not much larger than a lunchbox and weigh very little so they can easily be moved from place to place with little hassle.

So why the difference in size? The simple answer is down to one thing and that is power.


Given the varying output levels of electricity required, the types of generators available differ hugely in how much power they produce. The larger portable generators produce enough power to keep the basic amenities of a normal home up and running should there be a disruption in mains power. They are not however designed as a long term solution or even to keep all the heavy duty appliances running in the event of a main power failure.

If you are looking for a generator to run power tools or high power consuming appliances such as refrigerators, then you will definitely be needing a larger generator to make sure you have a high enough power supply. If you just want a smaller power supply to use less demanding power tools such as drills and rotaries, then you can opt for a smaller and much more lightweight generator that will still be capable of producing a sufficient power output.

The smallest generators tend to be designed as recharging stations that can be used for everything from charging battery-operated power tools to cell phones and tablets. Before you begin your research, you will need to be sure of exactly how much power you want from your generator to make sure you are buying the most suitable one.

Fuel Efficiency

All generators require some kind of fuel in order to produce a power supply. Most rely on gasoline as it is a simple and easy to obtain fuel that can generate lots of power when burned. Other generators rely on internal batteries and solar energy.

When buying a generator, you should always try to find out its level of fuel efficiency, because if you are planning to use it quite a lot, buying a generator that guzzles gas could end up being very costly in the long run.


Last but not least is the price. Price is the elephant in the room that we must always consider when buying anything. Since the larger generators will set you back quite a bit of cash, it is important to make sure that you have the budget to buy what you need instead of what you think you can get away with. Trying to save money could really end up costing you in the long run.

It is always a really good idea to sit down and come up with a list of requirements you will need your generator to fulfill. Once you have done that then you should work out a reasonable figure on how much you have to spend and see how well it fits your requirements.

Once again, you should never buy inferior or poor quality products to try to save money. That said, you should also make sure that you are not buying an expensive generator that is above and beyond what you need, especially if you only plan to use it now and then.

Another one of the mid-range power output heavyweights, this well-made generator from Durostar is definitely worth considering. It has a 7 HP engine that is able to get a really respectable 8 hours of running time from its 4-gallon gas tank.

DuroMax XP4400E 4,400 Watt 7.0 HP OHV 4-Cycle Gas Powered Portable Generator with Wheel Kit and Electric Start

DuroMax XP4400EMedium powered generator

Finding a larger generator with a wheel kit included as standard is a real plus. Many companies do allow for a wheel option that can be bolted onto the frame, but unfortunately they charge extra for the privilege. The optional extra, in this case, is a really durable cover that means that you can leave the generator out in the rain and don’t have to risk it getting wet.

The 7 horsepower engine produces a 3500-watt output that will surge to a whopping 4400 watts should the need arise. At 25% power, the 3-gallon tank will last around 8 hours, meaning that it gets and about an average level of gas efficiency.

It is an electric start unit which is definitely another plus provided it is well maintained. It will also shut itself off whenever it runs too low on oil preventing those horrible self-destruct episodes that generators in the past underwent whenever the user forgot to check the oil.

If all of the generators so far seem like complete overkill and you are only looking for a small generator to charge your phone, tablet or laptop, then this one might be better suited for your needs.

It has a much more modest 80-watt output that it is able to fuel in 3 different ways. You can opt for the 100% environmentally friendly solar panel charge or by connecting to your car’s 12V adapter or even through its internal battery which can be charged from the mains power.
