Best Budget Portable Generator Buyers Guide & F.A.Q

Portable generators are a great source of electricity in many situations. From powering an RV, charging a mobile phone, providing homes with power in an emergency, or working on a construction site, they can be extremely useful, even vital. 

Choosing a portable generator, however, is not always easy. What type do you need? How much power? Do you need it to be portable?

Does it have enough running time? All questions you will need the answers to. 

To help deal with these conundrums we have created a guide that will help you learn which portable generator is best for you. It will deal with the most common questions asked and so much more.

After all, a portable generator is not something that you should buy on a whim. You need to be armed with the correct information

What Are The Different Types Of Generators?

There are three main types of generators that may be used as a source of electricity in different situations. These are:

Portable Generator

Usually powered by gas or diesel a portable generator can provide temporary electrical power when needed. They use a combustion engine to conduct electricity and can be plugged into appliances via their sockets.

They have enough power to run a combination of electrical items such as TVs, freezers, and refrigerators. They are ideal for camping or RVs.

Inverter Generator

An inverter generator creates AC power via an engine connected to an alternator. It then converts the AC to DC by using a rectifier. It relies on high-tech magnets to do this and uses advanced electronic circuitry during its three phases; the output of AC, conversion to DC, inversion to AC.

They are more energy-efficient as the engine speed adjusts itself according to how much power is needed and can be set to any voltage and frequency when used with the proper equipment.

Inverter generators are best suited to car batteries and laptops and can be easily carried in cars, RV’s, and boats.

Standby Generator

Running on an electrical system that has an automatic switch to power up a device during periods of power loss, a standby generator is ideal for home emergencies, elevators, medical equipment, and fire protection systems.

They run on either liquid propane or natural gas and can sense power loss within seconds. They constantly monitor utility power and will run a self-check weekly to see that they are properly reacting to power loss.

What Do Generators Run On?

It goes without saying, but we’ll say it anyway, that generators do not run on thin air and need some kind of fuel to operate. Following are the four kinds of fuel that generators typically run on.


By far the most common type of fuel needed to run a generator, gasoline is relatively inexpensive and readily available making it very convenient. It is also safe to use and generators running on this fuel tend to come in smaller sizes and models making them extremely portable.

On the downside, however, gasoline is certainly not environmentally friendly and produces high emissions when in use. It also has a fairly short lifespan, around twelve months in storage, making it a challenge to keep.

Cold weather is also not a gasoline generator’s friend as they can be difficult to start in less than desirable weather.


Of all the fuels diesel is the least flammable making it the safest to use. It is also, like gasoline, readily available so convenient too. Diesel can run the most powerful generators that tend to last longer so long as they are maintained. It also has a shelf life of around twenty-four months, twice that of gasoline.

Diesel also, however, comes with its own set of cons. For one it is slightly more expensive than gasoline and propane, and two its emissions are sky-high. This means that use of a diesel generator should be limited as much as possible.


Providing great fuel efficiency, propane provides the cleanest running engine and the quietest. It is also pretty readily available and has a better shelf life than both diesel and gasoline.

It powers durable machines that can last for a long time and are ideal for small appliances or backup in an emergency. 

Propane is not ideal for large powered operations as the logistics to install them and store them safely is really quite prohibited. Propane is extremely flammable and potentially explosive to boot.

The fuel systems on propane generators are also highly complex and therefore can be partial to potentially frequent failures. 


By far and away solar power is the cleanest fuel type available for running a generator. It is free and also renewable making it highly desirable for use. It works by trapping the sun’s energy using solar panels and storing it up in a battery bank for later use.

There are also no moving parts in a solar generator making maintaining them incredibly easy. They can be used both outdoors and indoors since there are no fumes or emissions. 

Unfortunately, however, solar only produces a relatively low level of power especially compared to the other generator fuels. It is therefore not ideal for powering up heavy-duty and large appliances unless you have a big enough solar set-up.

What Might I Need A Generator For?

There are multiple reasons why you may use or need to use a generator but here are the four most common ones that you may come across.

Home Backup Power

Most people will know that a power outage, especially for longer periods, can be a nightmare to live through. You may be left with no lighting, food will be defrosting, there is no internet, and your smartphone battery may go flat.

It can feel like you have had all contact with the outside world cut off! 

However, by investing in a generator you can power up, at least, your home’s essentials, and for as long as you need. Generally, a standby generator is best suited for this kind of use as it has an automatic transfer switch. You could also run a portable generator as long as you install the switch.

Business Backup Power

When you think about it, virtually every business in operation would be affected by a power outage. Banks, insurance firms, bakeries, restaurants, farms, markets; all use electricity and would be lost without it.

Generators will allow them to continue trading as long as the power outage lasts.

Severe Weather Power Loss

Anyone who lives in a severe climate will benefit from having a generator. After all, power failures in extremely cold areas can be fatal!

With a generator, however, you can power essentials such as heating and lighting; though gasoline may not be the best option due to poor startup in the cold.

Tornado and hurricane areas may also benefit from having the aid of a generator as damage to power lines can last for a long time.

Construction Site Power

Construction workers often require the use of electricity for powering up tools and equipment that are essential to their trade. These tools make their jobs far easier, and quicker, after all, than working with manual non-powered tools.

Generators are ideal for this and can be used to power night lighting as well as tools. This means workers can continue working into the night, improving on efficiency again.

Recreational Power

By using a generator whilst camping or roaming around in your RV, you can transfer the convenience of being at home to your home-from-home. Make coffee, keep cool, charge gadgets, watch TV, and light up your tent, all with the power from a generator.

Portable, fuelled by gasoline are the most popular for recreational usage as they come in small sizes that are easily stored and moved.

Portable Power comes in handy for recreational use

How Much Power Will I Need In A Generator?

The amount of power you will require in a generator will depend on how and where you intend to use it.

Power requirement in a home, for example, is different from that of a camping trip or on a construction site. It will also be influenced by the items that you intend to power up.

Generator Power Required For Camping

The majority of people who go camping will at least take the basics such as kettles, lights, cameras, mobile phones, and perhaps even a laptop. Power consumption may include:

  • Kettle 600W
  • Blender 300W
  • Laptop charger 200W
  • Light Bulbs 100W

Generators for camping will need to be between 1000 and 2000 watts

Generator Power Required For An RV

Compared to standard camper vans, RV’s use a lot of power. This is due to them being fitted with heavy-duty appliances such as air conditioners, fridges, microwaves, and electric kettles. Generators for RV’s will need to be 3500 watts plus.

Generator Power Required For Homes

Home generator power requirements will vary depending not only on the electrical appliances and systems that you have but also on whether they will be running simultaneously or not. Appliances requiring large amounts of generator power include:

  • Clothes dryer 5400W
  • Heaters 4500W upwards
  • Small furnaces 3000W upwards
  • Water well pumps 3800W

Generators for homes will require around 5000 watts.

Generator Power For Construction Sites

Power tools and construction, in general, require a lot of power to function in the correct manner. For example, a ten-inch saw would need 4500 watts of start-up power and at least 1800 watts running. Generators for construction sites, therefore, need to be at least 7500 watts plus.

Portable power is essential for most construction sites

How To Determine The Specific Power Requirements Of An Appliance

The power requirements of an appliance will be located somewhere on the product itself. Where this is may vary with the most common positioning being:

  • The data tag on the motor
  • The name tag
  • The product stamp on the bottom of the appliance

Please note, most appliances list power requirements in amps but you require them in watts. The calculation to translate them is:

Watts = Volts x Amps

How To Determine The Amount Of Power You Need In Total

In the majority of circumstances, you will need your generator to run more than one appliance simultaneously. If this is the case, you will need to calculate the total power required. To do this you should:

  • First, list all the devices you want to run on the generator. For example, fridge, lights, heating, kettle, microwave etc.
  • Second, check all the appliance’s power requirements and note these on your list.
  • As the power requirements will be in amps you will need to change them into watts using the calculation listed above.
  • Finally, add all the watts up and you will have the minimum total power that you require in a generator.

Please note, you should add a couple of hundred extra watts onto your total. This is to make sure that the generator can handle any power fluctuations or additional needs in the future.

Using The Outlets

Most generators have several outlets; this means that you can spread the load out, making it more energy-efficient. However, you should also be aware that using all outlets can put a strain on the unit and affect longevity.

You should only really use all outlets in an emergency situation or when appliances are of low wattage.

How Noisy Are Generators?

Generators vary in the amount of noise they produce from the quiet to those loud enough that they will disturb the neighbors and potentially damage your hearing. 

For these reasons you should always choose one that is as quiet as possible; around 60 decibels is acceptable. At this noise level, you will be able to hold a comfortable conversation and not disturb everyone around you. 

Please note that professional generators will run louder than those used for camping etcetera, due to their higher power rating. Protective gear is essential for this type of generator to safeguard health and wellbeing.

Running Time

Generator running time is usually indicated at either 25% or 50% of their load. This shows how long your generator will run on a full tank of fuel at the set percentage of its total power.

If you are purchasing a generator for emergency power you should buy one with as large a fuel tank as possible. This will help ensure you do not run out of fuel during long power cuts.
