Portable Generator Review - Mini Generators

When looking for the best portable generator you should also keep an eye out for their size and what is best for your particular usage needs. Most of the machines in our review were neat medium sized unit that can be easily transported or stored in your home.

If you have a small living space, don’t need too much power or want to make sure the unit fits you home then the size of the best portable generators are a key factor to take into account.

You have the option to consider purchasing what we call mini generators which are not too big for your home, don’t weigh a lot and use less fuel. However, because of the size of their fuel tanks they tend to run out of fuel easier and you will therefore need to have a backup.

Best Mini Generator - WEN PowerPro 56101

WEN 56235i Super Quiet 2350-Watt Portable Inverter Generator with Fuel Shut Off, CARB Compliant, Ultra Lightweight, Black

From our best portable generator reviews we identified the WEN PowerPro 56101 as a great option. It is light, it produces a lot of power and it is easy to store in your home. It uses a 1-gallon gas tank and will give you enough energy for over 5 hours using a half load.

There are two outlets featured on the machine – one giving 120 V and the other with 12V. This portable generator is a very quiet machine and will only emit 60dB of noise when in operation.

You will also find that this machine is very cost affordable and you should pick one up for just about $125 – worth noting considering the price of larger units.

Portable Generator Review - Tri-Fuel Generators

When looking at the generator market you will notice that most machines use just one form of fuel. But there are machines out there that will use all three – gas, propane or natural gas. Having the option to use various fuel types can be very handy and give you flexibility. If you come across a Tri-fuel generator you might want to consider it from a flexibility perspective.

Best Tri-Fuel Generator - Sportsman GENTRi9K

Sportsman 4,000/3,500-Watt Dual Fuel Powered Portable Generator, Runs on LPG or Regular Gasoline

The Sportsman GENTRi9K Tri Fuel Generator is a great option as it scores very strongly in terms of the surge watts and the running watts it provides. Most importantly you are in control of the type of fuel you use with three different options.

Other portable generators are powered exclusively by propane, natural gas or gasoline – the GENTRi9K can use all three, making it much handier in situations where your preferred fuel type is not available.

This machine has an excellent control panel and offers eight outlets which will allow you to connect a diverse range of electrical sources to the machine. It will also allow you to receive up to 10 hours of power when using gas or five hours of power when using propane on a half load.

Portable Generator Review - Diesel Generators

If you decide to go for a diesel generator you should be aware of a couple of things. Diesel will give you better efficiency and will tend to operate much quieter than other machines. However, they do cost more to run.

Best Diesel Generator - Pulsar PG7000D

Pulsar PG2300iS 2,300W Portable Gas-Powered Inverter Generator with USB Outlet & Parallel Capability, CARB Compliant

One of the best diesel-fuelled portable generators is the Pulsar PG7000D. This is a 7000W portable unit with many features, and good surge and running wattage. The 4-gallon tank will last just as long as the larger tanks of other machines.

It uses a 418 cc OHV engine which is a better design than the average piston engine. There are a number of electrical outlets offered and you will be able to connect most types of electrical items to the machine.

It is slightly larger and heavier than others we reviewed so it will be a bit more difficult to transport or store in your home. As is the case with most diesel machines, it will cost you more to use but we consider it a superior product and one that might be worth the extra cost.

Portable Generator Review - Camping Generators

If you are the outdoor type and tend to enjoy camping trips you will be aware that purchasing a strong portable generator is very important. Camping generators tend to be designed specifically for what they say they do and are not suitable for home use. They are light and easily transported but still give you enough power to keep most of your necessities operating on your camping trip.

Best Camping Generator - Champion Power 75537i 3100-Watt

Champion Power Equipment 100416 10,000/8,000-Watt TRI Fuel Portable Natural Gas Generator, NG/LPG Hose Kits and CO Shield

The best camping generator we reviewed was the Champion Power 75537i 3100-Watt Invertor Generator. This is a strongly designed hardy machine that is lightweight and transportable. It gives you a good amount of power and is a particularly quiet machine emitting only 58dB of sound.

It uses gasoline and has a small 1.6-gallon tank that will last for about 8 hours using 25% of load. This means it is not ideal for a home backup supply but will be invaluable for camping trips, tailgating parties and daytrips.

Best Portable Generator Review: Solar Generators

One of the latest innovations in portable generators are machines that operate by using the power of the sun via specially designed solar panels. These machines will take the suns energy and store power for use later on.

They don’t recharge however when disconnected from the panels so you will need to ensure that the battery is fully charged before you head away. Most of the best of these types of generators will allow you to charge battery from a wall socket.

There are dozens of portable generator models to choose from. You should look out for weight, noise and power from each as well as what type of fuel they use. Also look out for the number of power sockets on each. Whatever your needs we hope these reviews will be of use.

Best All-Round Portable Generator - Honda EM5000S

Honda EG4000CLAN 4000-Watt 120/240-Volt Generator with CO-MINDER - 49-State

It is also suitable for contract or home use. The Honda EM5000S will not let you down—it's a safe, secure and quiet generator.

Rated Watts4000
Surge Watts7000
Voltage120/240 Single-Phase
Tank Size6.2 Gallons
Fuel TypeGasoline
Ignition Type(s)Recoil & Electric

This series of Honda generators have excellent power ratings. Starting at 4k watts and going as high as 10k watts, the user should identify the number of appliances that require power before choosing the best machine for you. If you are looking to cover a common family home, then the 5k generator will suffice. This unit also has a 7k watt surge rating.

The Honda EM5000S comes with a 6.2 gallon gas tank, not the biggest our reviews identified. We did note the fact that its 389cc engine means the Honda EM5000S portable generator is one of the most efficient of the non-inverting from those we reviewed.

Featuring a pull ignition as well as an electric ignition the Honda EM5000S offers a number of options. An electric ignition will save you back strain by powering the device with a touch of a button. There is a pull ignition option should you find your battery needs replacing.

The Honda EM5000S portable generator is not a noisy device. In fact, it does come in as one of the quieter emitting a noise level not too dissimilar to the average vacuum cleaner.

Honda EM5000S - Convenience & Efficiency

Run-time @ 50% Load11.2 Hours
Noise Level72 dB
Automatic Voltage RegulationYes (iAVR)

Our Honda EM5000S review identified an intelligent automatic voltage regulation system. Voltage regulators are a feature of all power generators but not all of them feature the iAVR system which our reviewers considered to be a world apart.

These features mean that your machine will feed a cleaner and more consistent power output to the various devices in your home. Any generator that is powered by an engine can occasionally see a fluctuation in terms of the power levels and this is something to be aware of.

The Honda EM5000S review shows that this unit’s iAVR system will eliminate any such power fluctuations by half that seen in other machines that don’t have such a system. A good feature but one of the reasons why this unit comes in that bit more expensive.

The Honda EM5000S’s circuit breakers will cut out overloading. It also has a low-oil shutdown which will automatically shut down the machine should you be out of oil, saving any potential damage to your device.

One of the extra features also includes ground-fault circuit interrupter (GFCI) outlets which are not seen in all other devices.

This feature measures the current going to and from your various appliances and will remove power if the returning current drops. This is a very useful extra safety option and can be lifesaving in certain scenarios.

Best Portable Generator Review - Honda EM5000S - Summary

Our reviews found that the Honda EM5000S is one of the better machines of its kind. It runs for longer, it offers an electric start option, is not noisy and is extremely safe. This is a device that will work well in both emergency and everyday scenarios reliably and safely.

The Sportsman GENTRi9K Tri Fuel Generator is a great option as it scores very strongly in terms of the surge watts and the running watts it provides.

Sportsman GENTRi9K - Convenience & Efficiency

Run-time @ 50% Load10 Hours
Noise Level58 dB

It is therefore and excellent choice if you need a strong machine for camping trips, on sites or for emergency scenarios where you may have experienced a sudden power outage. As long as you have fuel, you’ll be able to keep your devices and appliances running.

4. Best Diesel Generator - Pulsar PG7000D 7000W

 The Pulsar PG7000D has a lot of benefits, with good surge and running wattage. The 4-gallon tank will last just a long as bigger tanks seen in other machines. It uses a 418 cc OHV engine which is a better design than the average piston engine.

As is the case with most diesel machines, it will cost you more to use but we consider it a superior product and one that might be worth the extra cost.

The 418cc OHV engine is better that a normal piston engine. Five outlets of various types provide great scope for types of electrical items you can power.

While this machine still ranks as a portable unit, it is not as easy to move around than others reviewed. It is bigger, heavier and more difficult to transport around your home.

Our team also noted that it is more expensive than gasoline or natural gas models. However, it's a superior product and the Pulsar PG7000W is worth the expense.

The fuel tank on this Pulsar PG7000W is only 4 gallons, one of the smallest tanks our team assessed. And the Pulsar PG7000W's OHV engine offer several advantages over the piston engines on gasoline and natural gas models.

This portable generator will be more efficient when it comes to the amount of fuel that is used.

Fuel efficiency is great, with 1-gallon of gas lasting up to 8 hours.

The Pulsar PG7000W review team noted that the outlets cover almost every requirements. It has two 120V outlets, two twist outlets (for 120V and 120/240V), and one 12V 8.3-amp outlet. The latter is very handy if  you have USB powered devices because you can plug in a USB adapter.

One fact that can’t be overcome is the fact that machines such as these do make noise. However, the Pulsar 7000W features noise reduction technology that mutes the noise to below 70 dB. It's not the quietest machine, but it won’t be a nuisance if you are trying to sleep.

The WGen7500 Portable Generator from Westinghouse is another fantastic portable backup power appliance that will leave you and your home ready to face emergency power cut situations.

Like the Honda EM5000S it doesn't have the largest fuel tank, but with Westinghouse's 720cc 4-stroke OHV engine on the case, this is not an issue.

Rated Watts7500 Watts
Surge Watts9500 Watts
Voltage120/240 Single-Phase
Tank Size6.6 Gallons
Fuel TypeGasoline
Ignition TypeRecoil, Electric & Remote Key Fob

Running at 12.8hp, this is one of the most ferociously powerful generators for its size. With 9,000W starting power and 7,500W running, the power is considerable. With a 6.6-gallon fuel tank, and running on gasoline, this will provide more than 10 hours of backup power on a half load.

But it's not all brute force. The generator offers three start-up options (recoil, electric start and key fob remote), and can be easily started even at the lowest temperatures.

Included in the WGen7500 package are a battery, oil funnel, rear wheels (which will be required if you need to move this around) and a wireless remote.

In terms of efficiency, it would be difficult to fault the Westinghouse WGen7500. This generator is powerful enough to provide backup to any standard domestic electrical equipment.

Its Automatic Voltage Regulator (AVR) and Circuit Breaker Protection ensures that your appliances and power equipment will be safe from potentially harmful voltage surges.

However, the 71dB maximum operational noise level, measured at 7m (23ft), will make this less than suitable for users who are sensitive to mechanical noise. The noise probably rules the WGen7500 out from use on campsites, meaning that this one for home use only.

This generator, for all its power, does not have quite as extensive a range of outlets as, for example, the HondaEM5000S. There are two 120V 20A duplex outlets, and one twist-lock 120/240V receptable.

On the plus side, the control panel design is simplicity itself, and all outlets have durable rubber covers to help safeguard against inclement weather conditions. The control panel also has a digital hour meter that notifies when maintenance is necessary, helping to ensure longevity.

Westinghouse WGen7500 Portable Generator - Pros and Cons
Good mix of affordability & power.Quite heavy: not the most portable unit.
Easy to assemble and get running.Rather loud for a portable generator.
Ultra convenient remote start and other startup options.
Powerful enough to handle high surge loads.

This unit could not be more safe to use. Its GFCI outlet measures current to and from the appliances being powered, and will reduce its outgoing power in response to any drops in returning current.

Its sturdy, hardened-steel frame includes roll bars on top that provide additional protection for 6.6-gallon fuel tank. The automatic low oil protection technology will shut down the generator when the oil level is low, or if it overheats or loses viscosity.

It's also compliant with the regulations of the California Air Resources Board (CARB), and is backed by a generous three-year warranty.

Customers will also benefit from a super nationwide service and support network. The Westinghouse website is comprehensive and easy to navigate, including an online support center that's contactable by email.

Best Portable Generator Review - Westinghouse WGen7500 - Summary

The power comes with a price, however. It is one of the heaviest units on the market, weighing 200lbs, although its supplied portable wheel kit makes it relatively easy to move around.

However, its markedly loud operational noise levels will make this less attractive for regular use around the home or on campsite.

On balance, our view is that for an appliance required almost exclusively for emergency situations, these shortcomings are outweighed by the positives.

The WGen7500 is an ideal blend of affordability with power and reliability. It has fine touch operations, down to its remote start, and is powerful enough to handle high surge loads.

7. Best Portable Generator Review - DuroStar DS4000S

DuroStar DS4000S Portable Generator, Yellow/Black

This is a durable, rugged portable generator with a decent 3,300 Watts of starting power (4,000 Watts starting and surge). The DuroStar DS4000S is not the most powerful unit on the market, but it's great value for money.

The brand is noted for its power, performance and affordability, and the DS4000S is no exception.

DuroStar DS4000S - Specifications

Run-time @ 50% Load8 hours
Noise Level69dB
Automatic Voltage RegulationNo

If you have little or no experience with using power generators, and your requirements are limited to domestic appliances only, then this could be the very unit for you.

A steady supply of 3,300 Watts will be perfect for most requirements, and while a little noisy compared to others, the DS4000S is also effective in remote locations such as campsites or building sites.

Although the manual recoil start method is not to everyone's taste, this one, dubbed 'EZ-pull' by DuroStar, really is easy to get going. There is a host of other features that will help the generator novice to keep their unit in tip top condition.

The gas-powered 7hp air-cooled overhead valve engine that makes this unit a rugged workhorse, suitable for a variety of uses. Please note, therefore, that this unit is not CARB-compliant, so cannot be used in California.

Outlets2 x 120V/20A Household

Although the operational noise level of 69dB is on the loud side, the muffler system ensures that it does not get louder than this. It's a pretty good result, quieter than many of the other units here, but if you're sensitive to noise, you might want to think twice.

However, the run-time for a generator of this size is very good indeed—giving users 8 hours of power when running on a half load. The air-cooled 7hp engine is a powerful but fuel-efficient driver for this system.

A sturdy steel frame around the engine and fuel tank keeps things running steady, with isolated mounts that minimise vibrations. However, the lack of Automatic Voltage Regulation means you'll have to be careful when powering more sensitive electronics.

Much of the weight of this unit, for such a modestly sized system, has gone into ensuring rugged protection for the engine and minimised noise.

This is achieved by a strong steel roll bar housing, which also makes it more convenient to lift the unit. However, the 94lbs weight might be too much for some to lift comfortably. There is a portable wheel kit—not supplied—which makes this easier.

The weight also stems from the mufflers used in the casing to minimise operational noise. However, at 69dB, this may not be enough for some tastes.

Overall, though, this is a pretty solid design. The operating dashboard makes it easy to run the appliance, and has such handy little touches such as a fuel gauge that some other manufacturers do not provide. Easy to start, even in harsh weather, this is a good 'starter level' portable generator.

DuroStar DS4000S - Safety & Warranty

DuroStar DS4000S Portable Generator - Pros and Cons
Powerful enough for most domestic appliances.A little on the loud side for camping and RVs.

All-steel build makes the unit more durable.Rather heavy, and a wheel kit is not included in the package.
Price tag is attractive compared to others in this class.The 1-Year Warranty is lower than other manufacturers provide.

The circuit breaker outlet is a welcome addition to the DuroStar DS4000S, enhancing its safety for users. In addition, the low-oil shutdown helps to protect the engine and ensure its longer operational iife.

The DuroStar DS4000S is covered by a 1-Year Limited Factory Warranty, and by a 30-Day Satisfaction Guarantee. Fitted with its noise mufflers and a spark arrestor, the unit is also approved by the Environmental Protection Agency.

However, please note that is not certified by the California Air Resources Board (CARB) and so cannot be used legally in California.

Customer Support is good, with full details of email and phone contacts available on the website of manufacturers DuroMax Next Generation Power Systems, along with an extensive resources section.

Best Portable Generator Review - DuroStar DS4000S - Summary

There are perhaps as many pros as cons with the DuroStar DS4000S. However, we would recommend it as a solid starter unit for anyone new to using a portable generator.

It's quite loud, albeit still quieter than some of the other units on this post, and is easy to set up and get going out of the box. Some users have reported that refuelling is slightly awkward, but overall, it's reliable in all weather conditions.

The lack of CARB compliance is a bit of a shortcoming, however, as it has been approved by the EPA, it's safe for use in national parks and other public areas.

Best of all, it's great value for money, and provides sufficient power for a variety of needs, right up to heavy-duty appliances such as HVAC systems in homes or RVs.

Best Portable Generator Review - Buffalo Tools Sportsman 1000 Watt - Summary

One of the greatest selling points of this unit is affordability. The power quality is good, albeit limited, but at this price range it is difficult to quibble. The build quality of the appliance will not be to everyone's taste, because of its plastic-y feel.

9. Best Portable Generator Review - Yamaha EF2000iSv2

YAMAHA EF2200iS Inverter Generator, 2200 Watts, Blue

The Yamaha EF2000iSv2 is an update of the EF2000iS, which already has a formidable reputation in the portable generator market.

Compact and lightweight, with an eye-catching retro design, the EF2000iSv2 is easy to stow away, and it's quiet enough to make it equally suited for camping trips as well as domestic usage.

With its light weight and compact dimensions, the Yamaha EF2000iSv2 is fantastically convenient whether for use in the home or outdoors. With two 120V AC outlets, and one 8A 12V outlet for charging batteries, this generator is powerful enough for most standard small to medium home appliances.

Powered by its efficient, reliable OHV engine, the generator has a number of great features, including Smart Throttle, which adjusts engine speed according to load. With a quality build and absorbent rubber feet, any vibration and unwanted noise is minimised for smooth, comfortable operation.

It's beyond doubt that a generator this light and contact will not be powerful enough for some tastes. However, the appliance has parallel expansion ports that make it possible to double the power when paired with another EF2000iSv2.

Yamaha EF2000iSv2 - Convenience & Efficiency

2 x 120V 13.3/16.7A

For a unit of its size, this Yamaha generator runs for a surprisingly efficient 10.5 hours on a 25% load. The Smart Throttle feature uses a load-sensing RPM mechanism to vary the engine speed according to the load. Therefore, fuel efficiency is maximised according to your needs.

Smart Throttle—in addition to the overall quality of the build—also ensures that operational noise is minimised.

This unit emits an operational noise level of 51.5dB on quarter load right up to 61dB. Even at its loudest, it's unlikely that this generator will unduly disturb your neighbours, either at home or on the campsite.

A few design touches really set this appliance apart from the competition. A fuel gauge makes monitoring fuel levels much easier than some of the other generators reviewed here.

And a gasoline petcock means you will have none of the difficulties that can arise from stale fuel while the unit is in storage. All you have to do is use the petcock to shut the gasoline off from the engine and let the carburettor run dry.

Other notable features include auto decompression, which helps with starting in cold weather. An additional auto warm-up facility assists the unit in providing power to heavier duty appliances.

The Briggs & Stratton Home Series 5000 portable generators are designed to power the general appliances in your home should you be affected by a power outage.

Generators of this size, 5000W, are the average size generator that's required to power a family home. They will keep electrical items such as home computers, washing machines and other devices running until power is restored.

The Briggs & Stratton Home Series 5000 review identified that this machine uses a Power Surge alternator, which provides 25 percent more wattage to cope with a power surge; a surge wattage that's higher than many of the other generators we considered.

This generator can cope with a surge power of more than 6.2k watts for almost 10 seconds.

This is a valuable feature and something that is often overlooked. Surge wattage is a very important function for any generators that start with electric motors. When starting these machines can use four times the wattage than when operating in a normal setting.

This generator has running wattage of 5,500w and a surge rating of 6,875w for up to 10 seconds. The medium sized Honeywell 5500 will fit nicely in a shed, bed of a pickup truck or a car trunk.

Our Honeywell 5500 review team noted a flaw with the machine. It identified that the engine is not the most efficient on the market. The 389cc overhead valve engine and 5.8-gallon fuel tank provide 9.1hs running time on a 50% power load.

The best portable generators tend to run for up to 14 hours on a 50% load. Therefore, the Honeywell 5500 will only work well in short term scenarios such as a temporary power cut. If you’re hit by longer outages, you'll need fuel backup in order to ensure sufficient power for your appliances.

The Honeywell 5500 electric start function is a standout feature. However a recoil rope is included if the machine has not been used for some time and the battery dies.

You will need to reset circuit breakers should the outlet be overloaded but this shouldn’t be a major concern.

The Honeywell 5500 review revealed a lack of safety elements that are seen in other machines. It doesn't have a spark arrestor, which prevents sparks from exiting the exhaust and starting a fire.

Also, the Honeywell 5500 portable generator doesn’t offer never-flat tyres available on other models. Therefore, its tyres may become flat if the generator is not in use for a long time. This will cause trouble if you need to move the machine around.

Our Yamaha EF5500DE review noted that the engine on this machine is extremely efficient and as a gas generator will work well in an emergency. You will find that you will have a nine-hour operation time if using a full load or a 12-hour operation time with a half load.

This feature will save you on operation costs and allowing the machine to perform efficiently when being used in different ways over the course of a day.

The Yamaha EF5500DE is not perfect. Our Yamaha EF5500DE review noted the fact that is doesn’t feature a very high surge power rating. The machine will operate on 4.5k watts but unfortunately will only handle surges up to an extra 1k watts. Surges feature most when a machine is kicking into action.

When in operation most electric motors will require 2 to four times the amount of wattage in startup mode. To explain a bit more - a 500-watt appliance could require 1,000 to 2,000 watts at startup.

For comparison, the best portable generator has a surge increase of 2,000 watts. The average surge increase is 1,250 watts.

The Yamaha EF5500DE portable generator offers a useful safety feature in the GFCI protection for the outlets you use.

This ground-fault circuit interrupter is a circuit breaker that enable the machine to measure the level of AC come to and going from the generator and the various appliances that are being powered.

The Yamaha EF5500DE counteracts any risk of electrocution by monitoring if the returning current has diminished.

If the current diminishes then it means that it has found some other route to earth. If this happens in the Yamaha EF5500DE portable generator the GCFI will kick into action and shut off the power supply.

Our Yamaha EF5500DE review identified a very useful extra safety addition. The generator has a sensor installed that will shut the machine’s engine down should the oil levels get too low.

This will both save your machine from any long term damage and ensure that you will have a good and reliable power source in the event of a power cut.

Best Portable Generators - FAQs

For those unacquainted with portable generators, our FAQs section will help you get to grips with some of the features and aspects of these products. Use our FAQs to attain a new understanding of portable generators. This will help you find the unit that is matched to your specific requirements.

Why should I invest in a portable generator?

There are several benefits that flow from investing in a portable generator. Chief among these is that the user attains a sense of security from the knowledge that they will not be left stranded in an unexpected power black-out.

While portable generators cannot power entire homes, they enable you to use your essential electrical devices while you wait for the power to come back on. Portable generators can also be used for a wide range of outdoor activities, such as camping, barbecues, etc.

Is the size and weight of my portable generator important?

Most of the lower wattage generators are actually quite compact light-weight, and usually have a built-in handle for easy transport, however there are heavier, larger units, but these are usually mounted on a wheel kit.

To find the generator that's the right size and weight for you, you must first consider how exactly you plan on using the generator. If it's simply for energy security in the home, larger & heavier units will not cause too much inconvenience.

However, for camping purposes, where it must be transported and moved around, you may want to choose a more lightweight and compact appliances.

Will I have to spend a lot of money for a decent portable generator?

The prices of portable generators vary drastically, depending on the wattage of the generator. Higher wattage models often reach into the thousands of dollars bracket. Meanwhile, good quality lower wattage generators can often cost less than $500.

Are portable generators very loud?

Most portable generators will register at a noise level of somewhere between 55 and 85 dBA, with us classing anything below 70dB to be relatively quiet.

For comparison, the average human conversation will register at somewhere around 60dB. Therefore, for a generator to only put out a noise level that is slightly higher is quite impressive.

Is there a specific type of fuel that my generator will run off?

The specific type of fuel that your portable generator requires to function will be outlined in the device's user manual. There will also be instructions for changing the oil, as well as all the other information you need to run your generator safely and effectively.

Can I store my fuel for a long time?

Generally speaking, fuel begins to deteriorate after a month, so we strongly advise you to add a suitable fuel stabilizer, which will prevent the ethanol contents from damaging combustion-related components in your generator.

That being said, we always advise that you drain your generator of fuel and put the oil to other uses, rather than leave it in there for extended periods of time.

Will I have to operate my generator often?

In short, yes, you have to operate your generator regularly to prevent damage due to long-term fuel storage. Generally speaking, we recommend using your generator once a month, or as often as specified in the included user manual.

How do I start up my portable generator if I haven't used it in a while?

The most important part about starting up a generator after a long period of time is ensuring your safety. First, take your generator out into a clear and very well ventilated area. All parts need to be checked to ensure they are operational, with particular attention payed to the carburettor.

Further, the generator will then need thorough cleaning, following the instructions as laid out in the user manual.

Once cleaning is finished, refill the generator with fresh fuel, and a new spark plug. Oil level must also be checked to ensure that the machine has enough. Finally, once all safety precautions have been observed, begin start-up.

What do I do if water accidentally gets into my portable generator?

Water can create some serious safety hazards, and damage the components of your generator. If water gets inside your generator, power it off as soon as possible, if it is safe to do so.

Your user manual should contain instructions on what to do in this scenario. If it is unsafe for you to deal with the situation, we recommend that you distance yourself from the generator and call a company representative.

Where is the best place to set up a portable generator?

It is absolutely vital that you do not set up your generator indoors, and this includes structures such as tents and garages. You should place your generator outside in a well ventilated shelter.

This is of the utmost importance as generators have a number of exhaust fumes that can cause serious poisoning if allowed to build up indoors (such as Carbon Monoxide).

Will my portable generator need a wheel kit?

If your generator is small enough and light enough for you to transport manually with ease we would say that there is no need for a wheel kit.

Conversely, heavy or large generators typically already come mounted into a wheel kit, so there is normally no need for a wheel kit. That being said, if you find your generator to be too inconvenient, or heavy to move, we do recommend your purchase a wheel kit.

Is there any difference between surge wattage and rated wattage?

The surge wattage of your generator refers to the peak output that can be produced, usually for quite a short amount of time, whereas the rated wattage of a generator refers to the amount of power it can continuously produce.

What does 'electric start' mean?

Generators with 'electric start' functionality have simple push-button activation. This feature is usually present on many of the more modern, recently produced generators. The other, more common mechanism features a pull-cord configuration.

Both set-ups have their downfalls, such as the electric start not working at times due to an empty battery, or the cord being too laborious of a start-up procedure for some people. Therefore we believe the best generators have both start-up mechanisms, which work as back-ups for each other.
