Pre-Purchase Considerations For Electric Portable Generators
To help you make the best choice when purchasing your portable generator, we’ve put together a comprehensive buyer’s guide with the key elements you’ll need to consider before making a selection.
There are several pre-purchase considerations to bear in mind if you are in the market for a portable generator.
First, you need to determine how much power you require. For instance, your fridge may require 700 watts to run but as much as 2100 watts to start up. Identify your purpose for making the purchase, and determine the wattage you need accordingly.
You also need to find out the kind of outlets you require. For example, smaller generators typically have a few 120V AC outlets plus USB ports, while larger devices of 4,000 watts often have 240V plugs too. If you want to hire an electrician to wire the generator to your panel, you’ll need to purchase a generator with a 240V plug.
You’ll need to consider how often you intend to use the generator. If you only intend to use a generator in the event of an emergency, a shorter warranty time would suffice. On the other hand, if you intend to use the generator daily for work, a longer warranty is your best pick.
Consider the size of the fuel tank before purchasing the best portable generator to meet your needs. The larger the fuel tank is, the more time you can go without having to add more fuel. You should also decide whether you’d prefer a recoil cord you can pull or if you like an electric start instead.
Noise level is another factor to consider. If you’re going to be in an area where a quiet engine is essential (like a campsite), noise level is going to matter. However, if you plan on purchasing your generator to power large tools at a loud construction site, this probably won’t be an issue.
Types of Generators
There are three main types of generators. The type discussed in this guide is a portable generator. Portable generators run on diesel or gas fuel and offer temporary power for users.
The second type of generator is an inverter generator. Inverter generators run on an engine linked to an alternator for AC power. They also feature a rectifier to transition AC power to DC power.
The third type of generator is a standby generator. A standby generator is electrically powered by an automatic transfer switch that turns on the device during a power outage.
Benefits of Portable Generators
The first benefit of portable generators is clear—they are very portable! You can bring them with you from one place to the next with ease, whether that be your house, a campsite, RV, worksite, or otherwise.
What’s more, portable generators will help you save big if you live in an area that experiences a lot of storms. The generator will keep your appliances running if an unexpected outage occurs and help you avoid your devices dying or food spoiling. Portable generators are also fantastic power sources for gardens or sheds, so you can really use them for any electrical needs you have.
Another benefit of portable generators is that they are easy to use. Not only are they extremely mobile, but they are designed for simple user operation. Many portable generators feature circuit breaker protection and guards, so they are safe and secure for anyone to maneuver and operate.
Portable Generator Questions & Answers
