What Factors Should You Consider Before Buying a Portable Generator?

It can be a very expensive mistake to buy a portable generator and later realize that it does not meet all your power requirements. You, therefore, need to take your time and buy the best-suited generator for your current needs otherwise you will regret later. Below are tips which will aid you to choose the best.

How Can You Know the Specific Power Requirements of an Appliance?

To be able to estimate the overall power required to run all your appliances, you need to know the power consumption of each device. It is straight forward to know the power rating of any machine; just check the bottom of the gadget, and you will get a product stamp which has the rating. All appliances have this rating. However, you may be confused by some because they may have their wattage in amps. This is because the voltage can differ depending on your country and the intended market of the appliance. Do not worry, use the below equation and you will get the power in watts.

Watts = Volts x Amps

Watt is the power of your generator. It is the figure you will use to buy a portable generator which will run all your appliances simultaneously as we are going to see later.

If you are wondering what the value of the voltage is, put 120V, at least for most of the gadgets. However, before you start calculating power using our generator wattage calculator, check the voltage of your devices because there are some which use 240 V. In addition, you can find some appliances with a small switch which you can use to set the voltage. Do not attempt to change the voltage of the appliance because this can make them malfunction when switched on. In brief, you can quickly get the value of voltage by reading it on the tool.

The Quietness of Operation

Generators that produce earsplitting noise while in operation are environmental hazards due to noise pollution and also pause a health risk as they can cause hearing impairment. You are therefore advised to invest in a portable generator that operates as noiselessly as possible, or alternatively, use long cables to facilitate setting up your generator at a reasonable distance in order to minimize the noise hazard. Portable generator should run at 60 decibels noise level. Anything above that is unacceptable. This level allows normal conversations to be held comfortably and helps avoid being a public nuisance by breaching peace in the neighborhood through noise pollution. You can be sued if you produce noise above 60dB. The following are noise levels of various objects measured in decibel:

Whispering – 30 dB

Refrigerator – 50dB

Vacuum cleaner – 70dB

Blender – 80dB

Industrial generators used in factories are usually louder due to their high power voltage. Therefore, those operating or using industrial generators are recommended to use protective ear gear to avoid damaging their hearing. You should, therefore, read instruction manuals and do extensive research on how to safely use a generator without endangering your health or causing an environmental hazard.

Fuel Efficiency

Inverters modulate engine speed thereby making them up to 40% better than ordinary models at fuel consumption, in relation to ongoing power needs. This is the main reason why inverters are small in size and a bit more costly.

An ordinary generator needs to sustain an unchanging RPM to supply the required amount of power, which is normally about 3600 RPM. Increased power demand leads to more fuel being used to ensure efficient running. However, the engine must sustain a minimum 3600 RPM even under minimal loads.

Inverter portable generator can operate at much lower momentum since the technology used in its design enables them to continuously maintain the frequency of power release with no corresponding engine RPM increase. Due to this, an IG uses less fuel corresponding to low power demands, thereby conserving fuel to cope up with increased load requirements. It also means that the inverter portable generator are less noisy compared with the conventional generator.

Due to the differences in their designs, the operation duration of the two models of generators differs a lot. Ordinary generators are modeled to give a particular power supply irrespective of their size. Therefore, their fuel tanks are generally larger than those of IG. A larger tank means that the generator will be heavy.

IG’s are, as a rule, modeled with the intention of being smaller and easy to carry. This dramatically determines the fuel it can hold. Despite the smaller fuel tanks, a great number of IG’s can operate for up to 10 hours without adding fuel because their engines are highly efficient.

The more efficient an engine, the more it has added benefits of less air pollution that results from exhaust emissions. It is, therefore, true that IG has far much less carbon footprint than the conventional ones.

Fuel Capacity

You may have realized that inverter portable generators are smaller in size and smarter than the conventional generators. They are also more portable due to their lightness than the common generators. However, this comes at a cost. The tank has to be smaller to make them light. Since there is nothing much which can be done to make the engine small, the tank has to be minimized.

Consequently, the capacity of the inverter generators holds up to two gallons of fuel. But this should not be an issue in the first place because inverter portable generators consume less fuel than the conventional ones. After all, you may not exhaust all the tankful fuel in one sitting if you have a generator as a standby as you wait for the mains power to return.

The other reason why the inverter generators are petite is that they have other electronics which aid in converting the current to DC then to AC before supplying it to your appliances. They also have a microprocessor which ensures that every drop of fuel consumed is converted to electric energy.

On the other hand, conventional generators cannot regulate the engine speed with the power demand. For example, a 4000 watts conventional generator will use the same amount of fuel to power a 3500 watts appliance and a 2000 appliance. This makes them unrealistically inefficient.

It is therefore prudent to have an inverter generator because of the fuel you might lose with a conventional one in the long run.

Power Quality

The main difference between the inverter portable generator and the conventional is the quality of the power produced. The conventional generators have a straightforward design; the electric energy is produced from the alternator which revolves using the fuel power.  The electric current generated is then directly connected to the cords which supply the power to your appliances. This has the main disadvantage; the power produced can destroy your electronics.

However, the inverter generators go an extra mile to make the power produced superior and safe for your appliances just like the main grid power.

The power output of the inverter generator does not pass directly to your appliances. Instead, it is channeled to a rectifier which changes the AC to DC. It also has capacitors which prevent current fluctuations. After this, the inverter converts the DC again to AC. This current has the required frequency of 60Hz and hence cannot destroy your appliances because it does not change with the engine throttle of the generator.


In a home setting, maybe the portability is not a big issue. This is because once you buy a whole house generator and find a safe place to store it, you are done. However, portability because vital if you are moving out. Generators which are designed to produce maximum power like the 10000 watts generators are usually very heavy. Some have a room specifically made for their storage. These are conventional generators.

On the other hand, if you need a simple generator to run your home, you can buy an inverter one because you can move it to other paces should a need arise. The design of the inverter generator ensures that they are low in weight and compact. One person can carry them around. They are therefore ideal for outdoor activities. You can use them in your RV, picnics or camps without feeling that you have extra baggage.


There are many factors which influence the cost of any generator. It all boils down to your own need. Sometimes you have to pay more to get a generator which will satisfy you. Below are some of the factors which determine the price.

  • The power generated.
  • How easy it is to use.
  • The noise level.
  • The manufacturer.

It is up for you to decide the features you want in a generator before you head to the stores. Many people nowadays prefer portable inverter generators to the conventional ones because of the design, the level of noise produced and the weight. If you have more power needs than what a single generator can produce, you can combine two. Generators from well-established companies like Honda and Yamaha are more expensive than others, because these are the best generator brands. However, there are some genuine new companies which make excellent generators.

Design and Repair

As far as design and repair are concerned, conventional models take the day. This is because conventional generators are just a motor and an engine. They, therefore, do not breakdown often, and when they do, it is easier to repair them than the inverter type which necessitates specialized personnel.

Inverter generators also do not breakdown when easily. However, when they do, it is more costly to repair them than the conventional. This is because they have intricate electronics besides the engine and the coils.

How to Determine the Amount of Power You Need

Majority of people use generators as a backup option during power outages. However, you can also use a generator to get power in other places like in construction sites, camping, to power up an RV or to extend electricity where the main power does not reach.

To determine the amount of power you need, it is, therefore, necessary to put into consideration the type and number of appliances you need to power. General home appliances, for example, will require less power than construction sites.

To get a realistic estimate of the amount of power you need in each situation, below are four essential guides.

Power Requirements in Homes

The type of appliances and electronics you have will definitely determine the amount of power need. However, if you have a lot of gadgets which are power intensive, you can decide which appliances are mandatory to run and which can wait for the power situation to normalize. For example, you can choose to do away with electric heaters. It is vital to understand each appliance’s power rating so that you can come up with the total power you need to run all your electronics and appliances.

Because some appliances consume far much more power than others, Consequently, it is critical to choose what to use and what to switch off. Some of the household equipment which you should consider includes:

  • Many furnaces consume about 3000W of power.
  • Clothes drier at 5400W.
  • A Washing machine has a 3600W rating.
  • Heaters are above 4500W.

From the above common appliances, it is now clear that it is hard to run all the devices simultaneously with a single simple portable generator. This is because the majority of them are rated from 3000 to 5000 watts. If you choose to operate only the necessary appliances, a single generator will keep your home running until the main power is back.

Power Requirements in Recreation

Power is needed everywhere you go. It is hard to do any meaningful activity without electric power. To make your outdoor activities effective, you need to have the power to charge your phones and laptops. This will ensure that you will still be connected to your work and family when you are out. Some recreational activities will require gadgets which need the power to run. Portable generators become handy in such cases. For example, you can carry your radio and speakers when you are out enjoying nature.

Power Requirements in Camps

When it comes to camping, you need to have as much comfort as possible. This comfort cannot be possible if you do not have a power source. Majority of camps do not have a main grid power connection. To be comfortable, you need a portable generator. Majority of cottages are not heavy power consumers, and a portable generator of about 1000W will suffice. However, some heavy campers will require a more powerful generator. To now the best portable generator you should have in your camp, you have to consider the rating of all the appliances you will carry. For a modest camp, you may need to take cameras, phones, laptops, lights, and cooking aids. You only need a small generator for such items. However, for more earnest camping, which has the following gadgets; you need a more efficient generator.

  • A coffee maker has a rating of 600W
  • Blender 300W
  • Multiple lights bulbs each at 100W

Power Requirement in RV

A motor home is almost as power hungry as any home. You, therefore, need a more powerful generator than in a camp. For an RV to be comfortable, you need appliances like air conditioners, heaters, mini refrigerators, microwaves, and electric cookers. Without these, your RVing experience will not be fulfilling. If you are staying in RV with your family, you must consider each person’s power consumption so that they can have a home away from home experience. You will still need the TVs and the Pcs for the entertainment.

All in all, the most significant consumer of the power in RV is the AC which runs on 2000W of power alone. To make matters worse, it sucks 3000W when starting.  It is, therefore, necessary to have a generator of more than 3500 watts in your RV.

However, if you need more power than this, you can connect two or more generators to get the required wattage because it is convenient to move with two portable generators than one which is massive.

Power Requirements at Construction Site

When it comes to construction, the tools used are usually very power-hungry. Tools like a standard 10-inch saw will require a power of 4500W when starting and 1800W when running. That is one machine. A construction site has several such types of equipment.

Furthermore, a majority of constriction tools work under load and therefore consume far much more power to overcome the strain. Luckily, some of portable generators can regulate the RPM of the engine otherwise you can spend a lot of fuel if you use the conventional generator. Because of the power demand, construction sites generators have a rating of over 7500W.

Generator Types and Specifications

There are several types of generators all meant to produce electric power to power appliances. All of them have one thing in common; they need external energy to rotate the magnetic field to convert rotational energy into electric energy. The source of this power is the main factor what makes generators different from each other. Conventional generators are known to destroy the complex electronics of appliances like phones and digital televisions. If you do not want to burn your appliances, get generators whose power output is clean.

Below are the types of portable generators you can find in the market.

Gas-Powered Generators

Gas-powered generators are the commonest generators. They are very common because they use gasoline which is cheaper than other fuels. This fuel is available everywhere mainly because it is also the main energy source for the cars. Furthermore, gasoline engines are relatively smaller and lighter than diesel, which makes this type of generator convenient to use in a home and office settings.

However, gasoline-powered generators score poorly as far as safety is concerned — their emission when in operation is dangerous especially when operating in an enclosed area. Carbon monoxide poisoning is possible when gasoline generators are run in places where the circulation of air is reduced. Since the lifespan of gasoline is shorter compared to other sources of energy for generators, you can not store this in the generator tank for long. Lastly, these generators start poorly in winter.

Diesel-Powered Generators

Diesel-powered generators are the second most common in the market. This is because diesel is still relatively available in every part of the country. Diesel-powered generators are very efficient because they produce more power at a lower cost compared to gasoline-powered generators. This makes them ideal for heavy-duty tools. If you want to power up your construction tools, go for the diesel-powered generators because to maintain them is easy.

However, since diesel is the least flammable fuel, these generators have machines which are heavy to increase the compression. This makes them heavy and noisy when running. However, because of their dense compactness, they last longer and can run for more hours than their gasoline counterparts. They also emit dangerous fumes hence it is advisable to run them away from your home.

Propane-Powered Generators

Propane-powered generators are not common. Their main advantage compared to the above is their quietness when running and their efficiency. Propane fuel is relatively available but not as much as gasoline or diesel. Propane-powered generators are cheaper than diesel and more durable.

However, if you want to power big machines, propane-powered generators are not ideal. They may do well in your home setting, but they fail miserably to run power-hungry machines. Besides, propane gas under is highly flammable, and so they are prone to explosions. These generators have complex fuel systems which make them fail frequently.

Solar-Powered Generators

All the above type of generators uses energy which you must buy. Solar generators use the sun as the source of energy. This means it is free to run them. Furthermore, solar energy is renewable and dependable depending on your climatic region. Since these generators use a solar panel to harvest the solar energy, they are almost maintenance free and noiseless. Besides, you can run them inside your house because they do not produce fumes like the generators as mentioned earlier.

Unfortunately, you cannot use these generators to run heavy machines. The amount of power they produce is meager. You need them for keeping some of your home appliances running as you wait for the power outage to end but not for commercial purposes. During winter, when electric energy is much needed, these generators are entirely useless. They cannot operate at night or on cloudy days. Every time you want to harness power from the sun, you have to move them to places where there are no shadows. These inconveniences are what make solar-powered generators rare to find.

Inverter Generators

There is one critical disadvantage of all conventional generators; they can destroy sensitive electronic due to the power surges they produce. It is, therefore, dangerous to charge your laptop, for example, using power produced by a conventional generator. Inverter generators, on the other hand, produce the current in a sine wave which can not burn up your electronics. Also, these generators can alter their RPM depending on a load of power required. This alteration makes them very fuel efficient.

Features to Lookout for when Buying a Generator

There are many generators out there. Do not rely entirely on your salesman. Below are six critical features you should look out for when searching for the best portable generator for home use and not only.

Automatic Start

Generators are not stored inside the rooms you live for obvious reasons. When there is a power outage, you shouldn’t go out to start the generator. Buy a generator which has an automatic start so that it will ensure that there is a continuous supply of power.

Electric Start

Although generators are not used frequently, you still do not have to pull that string every time you want to start it. No everyone has that energy anyway. You should, therefore, ensure that the portable generator you buy has an electric start button.

Alternative Fuel Capacity

Your generator should run on many fuels. You should not rely on one fuel because you do not know when it can lack. You should have a dual fuel generator which runs on gasoline and propane or natural gas to be on the safe side.

Fuel Gauge

Your ideal portable generator should have a gauge so that you can know when you need to add the fuel.

Low-Oil Shutoff

Low oil in the engine is dangerous to the engine of the generator. Best generator shuts off when the oil level is low. This prevents engine seizure.

Multiple Outlets

Since you are not powering a single set of appliances, your generator should have more than two power outlets. This ensures that you will spread the wattage more evenly than when you have one outlet.

Removable Console

Make sure the portable generator you buy has a removable console. This ensures that you will not have cords running haphazardly in your compound.
