Features to Consider

Power Performance

You want to go for a portable generator that has excellent batteries, which are usually lithium-ion batteries. These are perfect because they don’t require any fuel or gasoline to operate, and no fumes will be produced when its in use. The battery should also be powerful enough for your devices, including smartphones, laptops, fans, and more. This way, it becomes a convenient power supply source for places such as campsites, tailgate parties, home improvement projects, and more. 

A key aspect to consider is also how you can recharge the battery. Simply put, you want a battery that can charge in the sun in a few hours, through the use of a solar panel. Furthermore, the generator should also be able to charge through a wall outlet or car cigarette port. Some generator brands even come with pure sine wave technology that provides safe power for your devices.

Safety Features and Noise Produced

While a generator is a reliable power supply unit, you should also note that these units tend to produce some noise during operation. This occurs due to the mechanical and magnetic components, which are in motion as it works to produce electricity. However, the noise level should not surpass the 50dba mark, as any level higher would be too loud.

On top of that, you want to consider the safety features that are available on the device. For instance, it should come with features such as a battery management system, short circuit protection, voltage control, and more. Some generators even feature sine wave AC outlets, which ensure a safe charge for your sensitive devices.

Portability and Safety Features

How convenient is the generator to carry? Well, you will have to evaluate various components of the unit, including the handles and its overall weight. On average, you want a unit that is between 3 to 10 kgs in weight. This way, you can easily carry it along, and you never have to worry about power shortages. Some generators come with unique anti-collision strips. These help to protect the generator against impact and heavy forces. Some brands makers even go as far as incorporating their products with several additional features. These include features such as temperature control, voltage control, short circuit protection, and more.

How to Choose the Right Generator for The Job

You have seen what occurs during natural disasters, storms, or perhaps when you are outdoors hiking. It's always good to have a reliable way through which you can power your favorite devices. To determine the amount of power your need, consider these key steps: 

  • What do you need to power? Make a list. Determine the items you need to power your appliances when there is a power outage. Some people have in-home medical tools, which are a priority.

  • In some cases, you have a computer or server that requires power regularly. If you need a generator for the job site or recreational purposes, then list the tools you will need to use a well. Being able to come up with this list will make it easy to narrow down a suitable brand for your needs. 

  • Determine the power required to start each appliance? Ensure that the generator is powerful enough to start your appliances. The starting watt level is the amount of electricity needed to start an appliance. Usually, its averages at two or three times more the power required to operate the appliance. If you don’t have owners manuals, then consider using a wattage calculator to make things easy. 

  • Estimate your average power needs. This is a two-part equation. First, you will have to add the total running watt level for all the tools that you want to power. This equals the total running watts the generator should produce to operate your equipment. Then, add this amount to the starting watt level of your device. You should now have the average amount of power required to start and operate your devices.

To buy a portable generator, consider these key steps:

  • Determine your power needs. On average, the power ratings for portable generators average between 1,000 to 10,000 watts.

  • Think about ease of use. Most portable generators come with wheels or ergonomic handles, which make them easy to carry. If you need one with wheels, consider going for one with never-flat tires for ease of transportation over rugged terrains.

  • Look for a generator with at least 6 hours of runtime. This provides you with sufficient time to complete your work, or perhaps wait to get a nearby power outlet. 

  • Count the number of outlets you need on the generator. This depends on the number of appliances that you need to power at the same time. Check the appliances to determine the type of outlets you need.
