Let us help you find a portable generator with our reviews

Last updated September, 2023

Our dependence on electricity or power is such that life comes to a standstill in case of power cuts or shortage of electricity. At such times, portables generators come handy as a convenient source and power back-up solution. Portable generators depend on fuel, diesel mostly, to produce power for domestic use. In fact, I have used a portable generator for my campsite, house and even while traveling in my RV. So, understanding what goes on behind the scenes, how a portable generator works, or alternatively fails, can definitely help in purchasing a dependable and truly portable unit.

Buying Guide: Things you MUST think about before buying a Portable Generator

​Why are you buying a Portable Generator?

​Generators are usually installed in places where power failure is a normal part of life, or where there is no direct access to power. For example, as a home backup power system, at campsites, RVs and so on. Now a portable generator is one that can be moved around and hence is a great convenience for most. At the same time, it is a necessity for people who live in an RV or those who camp out in the woods a lot. There are gasoline operated generators as well as natural gas operated ones but gasoline power is the most commonly available portable generator.

Even if you don’t face constant power failures, don’t go camping or have an RV, there are plenty of benefits to having a portable generator. For starters, hurricanes, storms, torrential rainfall and other natural phenomena disrupt usual power supply and it is in such situations that a portable generator proves its worth ten times over. Basically, you may not use the generator for most of the year but the 1 month you go through a horrible storm, you will be glad that you invested in a portable generator. Moreover, these generators are portable and they are designed for intermittent use. Unlike stationary generators that cost a lot and require expensive installation, planning, and rewiring, portable generators are easy to operate, selectively power a few appliances and have a long shelf life.

What to shop for when buying a Portable Generator

Just like no two individuals are ever alike, no two generators will ever be the same. Even if it uses the same engine, similar construction, performance will always differ. We have seen that performance difference usually arises out of a variety of factors. Here is a short summary of a few important points you may consider before looking for the best portable generator.

  • Portability: ​Size alone does not make a generator portable. The design too plays a crucial role. Handles with a comfortable grip and design, larger wheels, mounted on one end, peg stands on the other, ability to tilt the generator easily on its wheels are a few portability considerations to keep in mind.
  • ​Power or Wattage: Power is the combination of Volts and Amps or Watts = Volts X Amps. Since the Volt remains constant at either 120 Volt or 240 Volt, a higher wattage portable generator can deliver more Amps and thus power more appliances or heavy tools at once. When you purchase a portable generator you will come across two related terms – peak wattage and continuous wattage. Now continuous wattage or rated wattage is the power drawn by any device during its normal run but when a device starts or stops, it draws slightly more power, which is called the surge wattage or peak wattage. By convention and for safety purposes never operate a device that has a higher power requirement than the rated wattage of your portable generator. Hence, to find out what wattage your portable generator needs you to have to take into consideration the individually rated wattage of all the devices you plan on running and add them together. The same applies to the surge wattage when calculating the minimum surge power required from your generator.
  • ​​Noise Levels: Do not be under the misconception that portable generators should not make too much noise. They run a gasoline motor unseated and will, therefore, produce a lot of noise. Typically the noise levels range from 55 dBA to 85 dBA. Those that are quite under the 75dBA mark. If you plan on taking your generator to a campsite then make sure that it falls under the 75 dBA bracket. Generators with spark arrestors are another requirement for the campsite. They prevent burning embers from escaping out of the exhaust and safeguard your campsite from fire hazards. A simple way to understand how much power is too much is the horsepower of the motor. Higher the HP higher will be the noise.
  • Size: A largely sized generator will be difficult to haul around. So if its mostly for camping and RV Generator needs, get a smaller sized portable generator. However, if you plan on keeping the genset exclusively within your premises to provide backup power to your house then a larger generator would be a better idea.
  • Starter: ​There are two methods of starting namely – electric start and recoil start. Now recoil starting uses a pull cord that you drag on to kick start the motor. Its kind of similar to what you find in a lawn mower. A quality recoil starting mechanism will be easy to operate but a cheap generator might be difficult to power up by just relying on the pull cord. On the other hand electric start draws power from an auxiliary battery source to start the generator with the push of a button or by turning a key. This is simpler and much easier to start but it also requires your batteries to stay in good health. Hence, if you run out of battery, you are stuck with no power for the starter mechanism. It is therefore advisable to get a portable generator that comes with both, recoil start and electric start.

Did you know...

Without power you can’t do anything. Batteries can keep your appliances running for a few additional hours but without a power source, you will eventually lose out to darkness. Invest into a portable generator or a solar powered generator today and stay secured at times of power failure!

Here are a few pointers to get you started. Remember by no means, am I suggesting that this is a complete buying guide but it should serve as a good starting point.



I remember from my school days, wattage being defined as voltage multiplied by amperage (current). It is a simple term to understand and correlate for any physics major but with a little practice, you too can learn how to use this rating to your advantage. Most home appliances today have a clear description of the wattage, which is generally of two kinds.

  • Rated, Running or Continuous Wattage – The wattage that the appliance or device normally runs on.
  • Peak wattage – The maximum amount of wattage the appliance or device will use, usually when it starts or stops.

Noise Level

generator noise

​Noise or audible voice is measured in decibels or better referred to with the acronym dBA. When it comes to portable generators it is measured in terms of dBA at an industry-specific distance of about 21 feet or 7 meters. This is the standard measurement. The noise level for generators usually ranges from 55dBA to about 85dBA.

You may be aware of silent generators – these usually have a dBA of 75 or less. Anything above this limit is quite loud in comparison. Just to put things into perspective imagine the ruckus at a subway station as a train enters it. This is about 85 to 90dBA. So a silent portable generator isn’t actually very silent, it is just less noisy than an otherwise naked generator.

So, why is the noise level important? If you are going to use the generator in a domestic setting, it might actually be a big concern. For example, you are organizing a function, gathering or going to a campsite, the noise of the generator can have a dampening effect on the occasion and overall mood of the location or set up. You do not want people exercising their vocal cords, ears in a function or scare away the wilderness when you are out at a camp. Hence, when making a purchase decision know the kind of acceptable noise level and how much you can deviate on either side of the graph. Personally, for me, anything below 80dBA is fine.

Spark Arrestor Mechanism:

​Generators today come with a spark arrestor mechanism that prevents any sparks from escaping through the exhaust. This is essential if you plan on using the genset out in nature, or in your lawn, backyard since it can help reduce chances of potential fire or damage to the nearby floors and walls.

Size and Portability

​Depending on your usage pattern and expected movement of the generator, you will have to make a choice between portability, size and obviously the wattage. The heavier the generator, the more troublesome it will be to move. So, ensure that you assess well in advance how often you would need to move it around and remember that too small the size and you lose out on wattage.

For a typical home, a heavy generator will not be an issue, since you won’t move it around much from its designated area. However, if you are thinking of a campsite, you will need to be able to take it to load/unload from the trailer or RV, haul it to the campsite, fit it into an RV and more. Generators today tend to offer smaller wheels than before. While this reduces the weight, it can make things harder for you out camping. So basically, for homesteaders large sized, smaller wheels are better but for campers, smaller size with pneumatic large wheels are perfect.

​Starting Options

Generators are now available with a button start option or you could stick with a traditional recoil starter. The latter requires much more effort and can sometimes lead to injury. Whereas, a button start or electric start obviously offers ease of use with easy and quick operating mechanism. Yes, it makes things simpler and safer but a dead battery isn’t going to help you out. My advice – even if you get a Start button type portable generator, it should have a recoil cord too.

Top Rated Portable Generator Features:

  • Inverter Or Microprocessor Controls – A few high-end portable generators come with inbuilt voltage and ampere regulators or ICs that provide a steady current output, which is great for your home appliances
  • Number of Outlets – Ideally you should have one high Amp outlet and three low amp outlets. However, more the merrier provided the portable generator can provide power to all of them at the same time.
  • Lightning Bolt
    Fuel Gauge – I never look at portable generators that don’t have a fuel gauge as adding fuel to a generator once it exhausts its tank means you lose power for a while.
  • Lightning Bolt
    Oil Guard – A failsafe mechanism that prevents the generator from starting if the oil level hits a dangerous low. Usually found in stationary units, some portable generators do provide this, especially those with 10,000 watts or more rating.
  • Lightning Bolt
    Alternate Fuel – Most generators operate on diesel, propane or gas. Thankfully, you can convert a few models using a conversion kit to work with propane and natural gas alongside gasoline

Guide to Finding The Best Portable Generator Part 2:

Generators are now available with a button start option or you could stick with a traditional recoil starter. The latter requires much more effort and can sometimes lead to injury. Whereas, a button start or electric start obviously offers ease of use with easy and quick operating mechanism. Yes, it makes things simpler and safer but a dead battery isn’t going to help you out. My advice – even if you get a Start button type portable generator, it should have a recoil cord too.

If you are planning to buy or own a generator it is important to understand that a lot of factors play a crucial role in the buying decision. However, the most important and critical factor is to exactly know your total power requirements. Overusing the generator or exceeding it’s suggested limits has adverse effects on fuel efficient and causes irreparable damage to the generator. In certain cases, it also damages equipment feeding directly off the generator.

My advice is to first tabulate the total power consumption that you will require and then add about 15 percent extra just to be safe and factor in peak wattage.

A good way to start and know the exact requirements for any generator is to find the user or owner manual of all appliances add the suggested wattage for each unit to reach a conclusive, yet not exclusive number. If you can’t find the manual or are short of time, refer to the table given below and identify an average wattage for any appliance. This is more of a broad outline rather than an accurate calculation. I have tabulated the wattage based on my home appliance’s user manuals.

​Average Wattage Guide

Appliance Wattage Appliance Wattage
Personal Computer 500-2,000 Broiler 1,400
Planer 300-900 Central Air Conditioning 2,000-4,000
Refrigerator/Freezer 600-800 Chain Saw 1,000-1,800
Router 100-1,300 Circular Saw 1,200-1,600
Sanders (belt, disc, orbital) 250-1,500 Coffeemaker 400-800
Shop Vacuum 700-1,400 Drills (depends on size) 250-1,200
Space Heater 1,250 Electric Furnace 5,000-25,000
String Trimmer 600-1,100 Electric Range (oven only) 5,000
Sump Pump 1,500 Electric Range (one element) 2,500
Table Lamp (tri-lite) 150 Hair Dryer 1,200-1,500
Television 100-350 Heater (radiant) 1,300
3/4 HP Paint Sprayer 1,800 Hedge Clippers 300-1,000
Toaster 1,100-1,700 Hot Plate 1,250
Water Heater 3,000-4,500 Leaf Blower 1,000-1,400
Water Pump 1,000-2,000 Microwave 1,200
Window Air Conditioner 600-1,500 Miter Saw 500-1,000

Once you have the approximate wattage value, multiple the resultant number with two and then decide on a generator wattage. Once you know the wattage, it fairly narrows down your search criteria and will let you easily compare and buy a portable generator.

Now that you have concluded the total power your home requires, it’s time to select the right class of portable generator. Based on the total wattage, I have classified all portable generators into three categories.

Compact Portable Generators

Power – 3,000 to 4,000 Watts
Price – $400 to $800
What It Powers –
This sized portable generator powers just the basics such as a refrigerator (600 watts), TV (200 watts), Sump Pump (600 watts), Microwave (1,500 watts) and several lights limited to a total of 400 watts.

Compact generators with inverter capability is a good standby emergency generator. It even works well as a campsite generator. Small in size, lightweight, ultra-portable nature are its biggest advantage. But, don’t get your hopes up of having this unit power everything and be a whole house generator. You will have to be picky about the most important appliances.

Midsize Portable Generators

Power – 5,000 to 8,000 Watts
Price – $550 to $1200
What It Powers –
Can run a portable heater (1,300 watts), computer (400 watts), heating system (500 watts), secondary pump(600 watts), more lights along with a microwave, refrigerator, and television.

Mid-sized generators are an excellent backup generator. Usually no larger than a pressure washer, these generators can be kept in the storage shed and used immediately during emergency situations. They function well as hurricane or storm generators and are portable enough to power RVs and campsites too.

Large Portable Generators

Power – 10,000 Watts or more
Price – $2,000 to $3,000
What It Powers –
Along with everything that a midsize portable unit can power, Large generators can also power central air conditioners, large electric ranges, small water heats and more.

Large portables are actually harder to move around.
