Well, don’t worry, we’ve got you covered. We’ve collated this portable generator guide, which will allow you to find the right generator for you.

What to Look For

Don’t get us wrong, working out which portable generator is right for you is no mean feat. But it is possible! There are so many different ranges to explore, from small petrol models to 2kW diesel generators. Some generators are sensitive, or ones that are much larger for big projects.

Whether you are on the hunt for portable generators that can keep pace on the job site, or an easily maneuverable one for your home, we have the information you need. We’ve taken the time to gather a quick checklist of considerations you can follow to find the right generator for your task.


Before making any generator purchase, you need to ensure the wattage meets your needs. Ensure you work out exactly how much power you need for your job, and check to see if your generator meets those needs.

We get many people asking us what size of portable generator they should choose. Ultimately, the answer to this question will depend entirely on what you plan to use it for. Each portable generator has its wattage level, so you need to consider how much you require your portable generator to produce.

Regardless of what you are using it for, it will not be an efficient purchase if your wattage does not meet your needs.

Domestic or Professional

Some portable generators are ideal for leisure use or DIY hobbyists; some are designed specifically for commercial use.

Most top-quality generator stores or websites will have their ranges split into two categories, one for professional use generators and one for domestic use generators.


Do you want to run sensitive equipment like televisions or computers directly from your generator? If so, you need to ensure the generator you choose is suitable for that sort of job.

If you require power for anything that uses a microprocessor, you must choose a portable generator that suits sensitive electronics. This choice is essential as sensitive electrical items should not be run directly for a generator unless explicitly designed for this use.

Petrol or Diesel

It would help if you thought about how much it will cost to own a portable generator. As well as purchase price, which includes how much you will end up paying on fuel.

If you consider both diesel and petrol generators, you might think there is not much to consider here. However, there are key differences you should be aware of, such as the long-term costs and the upfront costs associated with each option.

Outdoor Use

If you are interested in using your portable generator in an outdoor setting, you will need to choose a weatherproof generator or is usable in wet conditions.

Standby and Specialist Generators

Will you be using your generator as a backup power supply for your property? Do you need a specialist generator to complete an industrial project?

Final Thoughts

In summary, if you follow these steps when making your purchase, you should have no trouble finding the right generator for you.

The final step to take once you think you have found the right generator is to look through independent reviews of the product and business to ensure you are getting a reliable and trustworthy generator that will last you a long time.

Whether for professional or casual use, there are so many generators to choose from; so if you’re still unsure, check out this handy list of portable generators that will help you make up your mind!
