Portable generators supply power to your home, appliances, small electronics, and even an RV in the event of a power outage or for a camping trip. Using a portable generator is relatively easy, and many models rely on dual fuel, gasoline, solar power, or propane for their ample power output. They also come with multiple outlets, quiet operation volumes, and are easy to transport where needed.

What to Consider When Choosing the Best Portable Generator
Choose a portable generator that suits your needs and circumstances. Making the right choice depends on understanding the product category and the crucial distinctions among the different types of portable generators that are generally available.
Generators vary by the number of watts they are capable of producing. To narrow the field, first determine how many watts you are going to need. Only you can answer that; the answer depends on which appliances you want to be able to run during a blackout.
Make a list of those must-have appliances, and write down how many watts each one needs in order to start. Know that lights typically require 60 to 200 watts to start, a refrigerator needs about 600 watts, and a space heater may need as many 1,500 watts. For many homeowners, a generator in the 5,000- to 7,000-watt range provides sufficient energy for power outages and large appliances.
That list of must-have appliances also has a bearing on whether the best generators for you to consider are ones that run on gas, propane, diesel, solar power, or are dual fuel capable.
- Dual fuel generators do the same job as a single fuel generator. The unit runs on propane or gasoline, allowing you to choose the fuel based on your needs, like power requirements, noise restrictions, and availability in your area. They have an isolated gasoline tank with a fuel capacity that ranges from as small as 2 gallons to more than 10 gallons. The larger the fuel tank on the generator, the longer the generator can provide gasoline-based power.
- Gas generators are very reliable options. As gasoline is a widely available fuel source, it is a common source of fuel for portable generators. The primary disadvantages are that gasoline is more expensive and less efficient than other fuel sources, and gasoline engines typically emit the highest levels of CO2. Also, storing gasoline for long periods of time requires a fuel stabilizer and can present a significant fire hazard if stored incorrectly.
- Diesel-fueled generators are also a reliable option. Although generators fueled by diesel aren’t as common as those fueled by gasoline, diesel is more affordable, more efficient, and can be stored for longer periods of time without a stabilizer. Diesel storage also doesn’t pose as significant of a fire hazard as gasoline.
- Propane-fueled generators are affordable and have a clean-burning source of fuel. Propane is a common fuel source for portable generators and may either be tied into a home’s primary propane gas tank or have a designated tank strictly for the generator. The main disadvantages are that propane isn’t as energy efficient as other fuel sources, and a generator fueled by propane will usually have a lower run-time and produce less power. Propane also presents a fire hazard if stored incorrectly.
- Solar generators are a great source of power for portable battery banks. Opposed to the energy used in gas generators, solar energy is silent, clean, and affordable. In fact, it’s also free. The disadvantages are that the power capacity is determined by the number and size of the panels and the size of the battery it charges. A solar panel’s ability to charge a battery is also dictated by the amount of available sun, so it isn’t as reliable a fuel source as other options.
Portable inverter generators produce electricity in three phases, first creating a high-frequency AC (alternating current), which is then inverted to a DC (direct current) and then inverted once again to your standard AC. Not only do portable inverter generators create more electricity, but this process also produces a very stable electrical flow, which is necessary for protecting delicate electronic systems such as computers and office equipment.
Powerful portable generators can get heavy in order to supply power to small or large appliances, power tools, homes, and even RVs. A good rule of thumb with generators is to know that the larger the unit is, the more power output it has. Many portable generators on the market range from 90 to 200 pounds, but they usually come with built-in handles and wheels to help with maneuvering and portability.
Alternatively, some small portable generators weigh between 20 and 50 pounds, but these supply less power than other comparable generators.
Portable gas-powered generators can be pretty loud. But some gas generators are built with noise-absorbing glass wool, special mufflers, and/or vibration-absorbing feet. If you anticipate noise being an issue, the best generators for you to consider are ones specially designed to do their work effectively but quietly.
A dual fuel generator will produce 50 to 90 dB (decibels)of noise, depending on the size of the generator, the type of fuel (remember that gasoline runs louder than propane), and the power output of the unit. Most generators will fall between 65 dB and 75 dB, which compares to the noise output of a hair dryer on low.
To understand the range of sound produced by a generator, consider these common sounds and their equivalent operating dB level:
- Refrigerator: 50 dB
- Hair dryer: 70 to 90 dB
- Motorcycle: 95 to 110 dB
The quietest dual fuel generators belong to a relatively small group of products that utilize dual fuel technology and inverter technology to create a dual fuel inverter generator.
While the above features are important aspects to consider before purchasing a portable generator, there are a few special features included in select models that add convenience and added power.
- Wheel kits are often sold separately, as are the transfer switches that enable you to wire the generator’s output to your electrical panel. Before you buy a generator, make certain you understand what, if any, components are going to be missing.
- Multiple outlets: Not only are multiple outlets convenient, but they also help distribute the generator’s electrical load when powering multiple devices. Having a portable generator with at least two household electrical outlets is recommended for efficiently spreading the electrical load. Generators may also have RV outlets and USB outlets.
- Line sharing: Purchasing a set of like-branded generators will often give you the ability to wire them in parallel, also known as load sharing. This means that by using a brand-specific kit, you can plug one generator into another to combine their wattages and produce even more power. Load sharing can also be a less expensive way to produce enough wattage to run large appliances or power everything in an RV at once.

Looking for more information about the portable generators available? Consider the answers to some of the most frequently asked questions about this particular type of generator.
Q: Can I use a portable generator to power the entire house?
Most portable generators will not provide enough power for a typical house. Portable generators are designed to power important items or circuits (if connected to the electrical panel) in a home. For more reliable backup power, consider a standby generator.
Q: Is 22kW enough to power the entire house?
While a 22kW generator may be enough to power most essentials and some smaller homes, it is usually not enough to power the entirety of most homes.
Q: Are portable generators loud?
Portable generators are known for being loud, but there are options with sound-dampening features that reduce the noise.
Q: Can I leave my portable generator running overnight?
It isn’t recommended to run a portable generator unattended, and this includes overnight. Most appliances will be fine if left unpowered. However, food in the refrigerator can go bad after 4 hours, and food in the freezer can become unsafe after 24 hours.
If you need to run a portable generator overnight, make sure it has been well maintained and is sitting on stable ground away from the house to eliminate any chance of tipping over or carbon monoxide poisoning.
