Size of Generators and their uses

Best Generators for Workshops

Before going to the list of the best portable generators for power tools, you must understand what generator size would work best for your workshop. Let us see the various sizes of generators available in the market and their use cases to increase your understanding.

2000 Watt Generators and Above

These are usually low-power generators used to run fans, lights, lightweight electronic gadgets, or small refrigerators in some cases. They cannot run a load of more than 15A. Hence, these types of generators are usually not fit for the workshop. However, if you have a small workshop with a load less than 15A, like small angle grinders, jigsaws, paint sprayer, sanders, and something like that, you can select this generator size. 

5000 Watt and Above

These generators are preferable for average-sized workshops globally. These can easily handle high-power loads like table saws, woodshops, and miter saws. In some cases, these can also be used to run water pumps.

7500 Watt Generators and Above

These generators are usually heavy with weight more than 200 pounds and convenient to run a complete setup at a workshop having several power tools and motors. Furthermore, these can run multiple high-power machines at the same time.

10,000 Watt Generators

It is the best option to running a shop off to a generator because of its ability to handle hefty loads. You can run a larger residential Jobsite or a complete workshop by plugging it directly into the breaker.


You can check your equipment’s load requirements at the worksite and analyze what generator size would be perfect for you. We have tried to clarify the use of each generator size with some examples above for your ease. You can resemble the instrument’s specifications with these examples for better analysis.

Our Recommendation

All the above-recommended products are well researched and beat other generators in performance, cost, safety, and other features in the given power ratings. If you are looking for a generator, you can blindly trust the suggested products above, depending on your power requirements.

Buying Guide for Generators

Here, we will tell you several factors that you must consider before buying a perfect generator for your workshop or household. If you take care of these factors while purchasing a generator, we guarantee that you will get the best one.

Load Ratings

First, you should consider the load ratings (in Wattage) of a generator according to your appliances power needs. Always buy a generator that can handle more power than the collective power of devices you want to operate with it. After that, check the current and voltage rating of generators. If your load demands 20A while the generator can supply only 15A current, go for another option. 

You can further check the guide above to determine the load requirements for different appliances.

Fuel Types

Another factor that you must consider is the generator fuel types. Always pick a generator depending on the fuel easily available in your area. If there is a deficiency of gasoline in your area, you should choose a gas-powered generator. In comparison, if there is a gas shortage in your area, there is no need to spend extra money on gas-powered generators. You can also buy dual fuel supported generators for your ease.

Tank Capacity and Working Hours

Tank capacity and working hours is another critical factor to determine the generator’s efficiency. Never buy a generator with a fuel capacity lesser than 6 gallons. Otherwise, it will provide fewer working hours and will cause difficulty for you. Further, select a generator with working hours more significant than 10 hours for easy management.

Type of Generator

Different types of fixed and portable generators are available in the market nowadays. You should always select a generator type depending on your working conditions. If your job requires the transfer of a generator various times, always buy a portable generator with solid wheels and a stand. If you want to fix the generator permanently in one place, you can buy a standby generator.


Noise is another critical that you check before purchasing a generator. Because some generators are so loud to make your living difficult, therefore, always buy a generator having noise-reducing mufflers or utilizing any other mechanism for noise control. Never purchase a generator with noise more than 72 dB

Frequently Asked Questions

How Can I Know What Generator is Perfect for me?

Think of devices you want to operate with the generator, and then look on their wattage label. Once you have all the Wattage information, you can add these Watts and find a generator with a rating greater than or equal to your calculated Watts. Then consider the fuel type, noise, tank capacity, and working hours from the buying guide given above.

What type of fuel is best for Generators?

Each fuel type has different advantages and disadvantages. For example, gasoline is readily available in the market. However, it is more flammable. On the other hand, gas is cheaper, but it reduces engine efficiency. Propane has a more significant shelf life, but it needs a larger tank for storage.

What appliances can I operate with my generator?

You can operate any electric appliance with the generator. However, always make sure that the generator power rating is substantial than your appliance needs. Otherwise, it can be harmful to your appliances and generator too.
