When and Why You Need a Portable Generator

Your journey to purchasing the right portable generator starts by understanding your needs. Here is a sneak peek of reasons you need to invest in a quality portable generator.

Get Affordable Power Everywhere

Electrical power has become one of the most sought-after resources in the world today. You need it to run your home, communicate, do business, have fun, and much more. Most people connect to the grid to access electricity. Unfortunately, the downing of transmission lines causes power outages which can last for hours.

Also, not all places are connected to the grid. To make matters worse, most green energy sources such as solar and wind are transient and may not be fully reliable to give electricity always. Therefore, truly get the freedom to access electricity from anywhere, anytime, you need a portable generator. Therefore, if you are an outdoor lover and often go camping, a portable generator is an ideal way to power your tent or RV. This way you can enjoy your perfectly brewed coffee or watch your TV thriller in the jungle.

Avoid Food Losses

It is not uncommon for people to stock their fridges. Unfortunately, all you need is for a power outage to strike and last a few hours for the food to go bad. Such a situation can put a dent in your wallet. The good news is that you can avoid such losses by investing in an affordable portable generator.

Keep Your Electric Car on The Road

If you own an electric car and an extended power outage strikes, you can get stranded and find it difficult to run errands. A portable generator can fix this by allowing you to charge your automobile and keep it running during such eventualities.

If You Live in Disaster Prone Area

It is not uncommon for utility companies to shut down power supply during disasters such as hurricanes, floods, and wildfires. These firms take such decisions as a precautionary measure to avoid electrical accidents which can be fatal and destructive. For instance, downed fire lines have been known to cause forest fires, especially during dry and windy conditions. A portable generator allows you to survive such harsh times without the need to suspend your normal uses of electricity.

Keep Your Water Taps Flowing

If you rely on water from your well, your taps can run dry during power blackouts, especially if you don’t have sufficient reserves in your storage tank. In such cases, life can be difficult because you can’t perform essential tasks such as flush the toilet, take a shower, cook, or do laundry. But if you have a portable generator, all you need is to power it up and connect your sump pump to get your taps flowing again.

If You Depend On Medical Equipment

Managing medical conditions is never easy. It even gets more complicated when you have to use electronic devices such as an oxygen tank or heart monitor. The devices require a constant supply of clean electricity. You cannot take chances, by depending on electricity from your utility company. In such cases, investing in the right portable generator is critical if you want to save the life of your loved one.

To Support Your Business or DIY Hobbyists

It is not uncommon for owners of startups and freelancers to work from home. Also, DIY diehards often have their workspaces in their homes.

Types of Portable Generators

As you shop for a top portable generator in the market, it pays to know the available options in the market. For instance, there are generators for both commercial and residential use. Commercial grade electric generators are characterized by high power output as they used to run heavy-duty equipment. On the other hand, portable generators for domestic or personal use are usually smaller in size and produce less power. However, a top portable generator for residential use can be used for commercial purposes.

Another way to categorize portable generators is by the type of fuel used to power it. The commonly used fuels are diesel, gasoline, and LPG. Most generators run on a single type of fuel such as diesel or gasoline. However, there are also designs that use multiple fuels such as gasoline and LPG. Dual fuel engines give clients the flexibility of using readily available and affordable fuel. This feature comes in handy during emergency situations when you cannot access your preferred fuel.

You can also classify portable generators by their design. For instance, most generators that run on fossil fuels, convert only 13-18 percent of the energy from the fuel to electrical power. Most of the energy produced is lost through heat, sound, and smoke.

To make electrical generators more efficient, manufacturers use electrical rectifiers built from powerful magnets. The resultant designs are known as inverter generators. These machines produce both AC and DC currents. People use them to power sensitive equipment due to the low harmonic distortion associated with their electricity. They also tend to be small and easy to carry.

Key considerations

When buying a portable generator, there are top considerations you need to make. Read on to discover them.

Pricing – How much does a portable generator cost?

The pricing of products determines their affordability. It, therefore, goes without saying that your budget affects your choice of a portable generator. A good quality portable generator goes for about $900 while a high-end dual fuel model with about 10,000 watts output goes for about $1,500.

While pricing is a major factor when buying an electrical generator, you shouldn’t rely on it solely to decide whether or not to buy a product. On the contrary, consider focusing on the generator features that meet your needs.

Features that Matter Most

When buying a portable generator try to see how its features meet your needs. For example, your machine of choice should power your equipment effectively. Now, let’s take a deep dive into the features you should look out for in a portable generator.

Power Output

As mentioned above, the power output of a generator determines whether or not you can use it to run your equipment. To estimate the power out of your ideal generator, compute the total wattage of the electronics you want to run.
