Buyer’s Guide

Although you are now aware of the best generator brands in the market, you also need to know more about selecting the best. Knowing the various types, features, and restrictions will help determine the best generator model for your power requirement.

Types of Generators

Types of Generators

There are four main types of generators, out of which you need to choose the type depending on your requirement. It will help you pick the best brand and model of generator suitable for your customized power needs. Let’s identify the various types of generators.

Home Standby Generators

These generators are installed permanently and will start automatically during a power outage. Hence, they need to be installed by an experienced professional with a permit. They are more costly and also supply more power than the other types. The latest models have high-end technology where self-diagnosis tests reveal if or when maintenance is needed. This will be notified to the user or the dealer through email.

You can choose the type of fuel you need, and propane will be the most sought due to less storage risk. However, natural gas will provide an unlimited supply of power. The power output ranges from 5,000 to 20,000 watts, and the typical cost of these generators is from $2,000 to $6,000 without installation.

Portable Generators

Portable generators are relatively cheaper and mostly run on gasoline. You need to add a fuel stabilizer for prolonged storage. These generators can be used anywhere because of their compact size and lightweight support portability. However, do not run them in closed spaces since the toxic fumes emitted during operation may be fatal. Store them at least 20 feet away from your home with a suitable structure to protect it from adverse weather. Here’s how to run a generator in the rain. Portable generators usually provide 3,000 – 8,500 watts, and the costs may vary from $400 to $2,500.

Inverter Generators

Inverter generators cost more than conventional portable generators due to the complexity of the engines. However, they are quieter and provide clean electricity, which is safe for sensitive electronics and communication devices such as mobile phones, smart TVs, and computers. The sophisticated exhaust systems are capable of reducing the noise to favorable levels. Safety precautions, efficient fuel management, and less emission are added benefits of inverter generators. The power output of these generators is from 1,500 to 6,500 watts. Inverter generators have a price range starting from $300 up to $4,000.

Portable Power Stations

These are also known as solar generators as they are powered by a chargeable battery or solar panels. They are relatively new to the market and will be a perfect choice for anyone concerned about noise generation. Portable power stations are extremely quiet as they have no engine like the other generators. Since they run on the charge, you may not be able to run them for extended periods without charging again. They need to recharge with electricity or solar power. These are more expensive and cost from $750 to $3,000 for an output range of 1,200 – 1,500 watts.

How To Choose The Best Generator?

There are some important factors to consider when choosing the best generator. This includes your power needs, construction of the generator, efficiency, and similar features. Let’s learn more about each of them to choose the best generator.

Power Needs

Start by figuring out how much power you need through the generator. Decide the number of appliances you will use and calculate the running wattage. Since the surge wattage is the amount of power consumed at the start of an appliance, it will be higher than the rated wattage. Add up the power required to run your appliances and choose a suitable generator with the rated wattage.


Most people prefer quieter generators, especially when used for outdoor activities. Most campsites and RV parks have limitations on the noise generation level allowed within the premises. Since you don’t want to ruin your night out, it will be best to go for a quieter generator. The latest models have built-in mufflers that minimize the sound levels. Most manufacturers mention the noise level at 25%, which could be way more when operating at a higher load. 


You need to choose something affordable within your budget. However, do not go for a generator that is too cheap. You might end up with a low-quality product. If you have a tight budget, you can choose a low-power generator that meets your basic power requirements. To find more about this, refer to: what can you run on a 3500-watt generator.


A reliable manufacturer often guarantees a sturdy build. Therefore, choose a generator with an original engine from a reputed company. This will ensure the product’s quality and give you a warranty with lifetime technical support.

Fuel Efficiency

Although most engines may look similar, they have various fuel efficiencies depending on the type of fuel used. Innovative manufacturers use modern technology to enhance the fuel economy depending on the power demand detected. The Eco-Throttle technology of Honda is one such example. This increases the runtime per gas tank without compromising the generator’s performance.


Easy setup, use, and maintenance will make your generator way better than most other features. Most new models have easy maintenance as they self-diagnose to determine the engine’s condition. The electric start, automatic low oil shutdown, fuel gauge, and digital monitoring increase the convenience for the user. 

Size and Weight

Choose a generator with the ideal size and weight depending on your requirement. This will be very important if you are looking for a portable generator. You can find much lighter and compact designs from reputed manufacturers offering the same wattage. You can also consider pairing up two generators parallelly to get the desired power output rather than going for a heavy generator.

Power Outlets

The number of power outlets available should be considered, especially in portable generators. They should have at least two AC outlets and one DC outlet. This will save the trouble of having to purchase additional power cords and converters.

Environmental Concerns

Although most new generators emit lesser toxic fumes, they are not completely eco-friendly. Therefore, some states will also have regulations on the types of generators, such as EPA and CARB compliant. Propane is cleaner than other fuels, and solar generators are always the best choice due to zero-emission.

Customer Service

The final yet most important concern is how the company will be helping you after-sales. Reliable manufacturers will assist you in providing lifetime technical support. So always choose a manufacturer with responsive customer service. Don’t forget to check the terms and conditions to identify the repairs offered without additional cost.

Frequently Asked Questions

how far does a generator need to be from a window

Do You Need a Transfer Switch for a Generator?

Yes, a generator used as an alternative power source for a building needs to have a transfer switch.
