Power Requirements

Determine Your Power Needs

When choosing a portable generator, the first step is to determine your power needs. What essential appliances or tools do you need to power during an outage or when you are camping? Make a list of these items and their wattage requirements. This will help you choose a generator with the right power output.

Wattage Calculation

To calculate the total wattage you need, add up the wattage requirements of all the appliances and tools on your list. Keep in mind that different appliances may require different wattages, so it’s important to consider each individual item. It’s better to overestimate your power needs to ensure you have enough power available.

Consider Starting Watts

Some appliances and tools have a higher starting wattage requirement than their running wattage. This is because they need additional power to start up. When choosing a generator, consider these starting watts to ensure it can handle the initial surge of power. It’s important to choose a generator that can handle both the running and starting wattage requirements of your devices.

Determine Runtime Requirements

Another important factor to consider is the runtime of the generator. How long do you need it to run without refueling? Think about how often you will be using the generator and for how long. This will help you determine the fuel tank capacity and estimate the runtime on a full tank.

Fuel Type


Gasoline-powered generators are the most common and widely available. They are usually more affordable and offer a higher power output. However, gasoline may not be readily available during emergencies or in remote locations. It also has a shorter shelf life compared to other fuel types.


Propane generators are a great alternative to gasoline. Propane is cleaner-burning and doesn’t degrade over time, making it a perfect choice for long-term storage. It is also readily available in tanks and can be easily refueled. However, propane generators may have a lower power output compared to their gasoline counterparts.


Diesel generators are known for their fuel efficiency and durability. They are often used in industrial settings or for heavy-duty applications. Diesel fuel has a longer shelf life and is more widely available than gasoline. However, diesel generators tend to be more expensive and require regular maintenance.

Power Output

Maximum Power Output

The maximum power output of a generator refers to the highest amount of power it can produce at any given time. It is important to choose a generator with a maximum power output that can handle the combined wattage requirements of your appliances and tools. This ensures that you have enough power for all your devices.

Rated Power Output

The rated power output of a generator is the amount of power it can continuously provide without overloading. This is the wattage you should consider when comparing different generator models. Make sure the rated power output is sufficient for your needs, taking into account both the starting and running wattage requirements of your devices.

Power Quality

In addition to the power output, it’s important to consider the quality of the power generated by the generator. Some sensitive electronics, such as laptops or smartphones, require a clean and stable power source. Look for generators with inverter technology, as they provide a consistent and reliable power output, free from voltage fluctuations or surges.


Weight and Size

Portable generators come in various sizes and weights. Consider how and where you will be using the generator. If you plan to take it camping or to different job sites, a lightweight and compact generator would be the most suitable choice. However, if the generator will stay in one location, such as your home during power outages, a larger and heavier generator may be acceptable.

Handle and Wheel Design

To enhance portability, many generators come with built-in handles and wheels. These features make it easier to move the generator from one place to another. Look for generators with ergonomic handles and sturdy wheels, as they can greatly facilitate transportation, especially in uneven terrain or tight spaces.

Noise Level

Importance of Noise Level

Generators can be noisy, which can be a concern, especially if you plan to use them in residential areas or campsites. High noise levels can be irritating to you and those around you. When choosing a generator, it’s important to consider its noise level and look for models that offer quieter operation.

Decibel Rating

The noise level of a generator is measured in decibels (dB). Lower decibel ratings indicate quieter operation. Look for generators with a decibel rating of 60 dB or lower, as this is considered a reasonable noise level for most outdoor activities. Some generators also have special features, such as noise-reducing enclosures or mufflers, to further minimize noise levels.

Runtime and Fuel Efficiency

Fuel Tank Capacity

The fuel tank capacity of a generator determines how long it can run before it needs to be refueled. Consider your runtime requirements and choose a generator with a fuel tank capacity that can provide power for the desired duration. Keep in mind that larger fuel tanks may make the generator bulkier and heavier.

Runtime on a Full Tank

The runtime on a full tank is an important factor to consider, especially during emergencies or while camping. The longer the generator can run on a full tank, the fewer interruptions you’ll experience. Some generators offer fuel efficiency features that can extend the runtime, allowing you to save fuel and reduce refueling frequency.

Fuel Efficiency

Fuel efficiency is a measure of how effectively the generator converts fuel into usable power. Generators with higher fuel efficiency can provide longer runtimes on the same amount of fuel. Look for models that offer energy-saving features, such as automatic idle control, which reduces fuel consumption when the generator is not under heavy load.

Additional Features

Electric Start

An electric start feature allows you to start the generator with the push of a button, eliminating the need for manual pulling of a starter rope. This can be a convenient feature, especially for those who may have difficulty starting the generator using traditional methods. Consider this feature if ease of use is a priority for you.

Multiple Outlets

Having multiple outlets on a generator can provide more flexibility in powering various appliances and tools simultaneously. Look for generators with a mix of outlet types, such as 120V household outlets and 240V twist-lock outlets. This will allow you to connect different devices to the generator without the need for additional adapters.

Low Oil Shutdown

A low oil shutdown feature automatically shuts off the generator when the oil level is too low. This helps protect the engine from damage and ensures it operates within safe parameters. This feature is particularly important for those who may forget to check the oil level regularly or during extended use.
