Portable generators are an efficient way to supply power to devices large and small in the event of a power outage. Unlike standby generators that are generally installed in a permanent location, a portable generator is ideal for occasional home use or on-the-go applications, like camping, tailgating, and more.

You’ll find small portable generators with just a few hundred watts of power up to large high-power models with 12,000 or more max watts. Many are somewhere in between, with popular portable generators for home use offering 3,000 to 5,000 watts of power. To tap into this power, consider the type and number of outlets the generator is equipped with. You should look for a mix of 120V household outlets and heavy-duty 120/240V outlets if you plan to operate both large and small appliances. Portable generators usually operate on gas, but some dual fuel models give you the option to utilize propane. Regardless of which type of generator you choose, be sure to check the decibel level to determine how noisy or quiet the generator will be.

Don’t get left in the dark during the next power outage or off-grid occasion. Check out these top portable generators on the market now.

Ryobi Bluetooth Inverter Generator


Inverter portable generators are popular for their quiet operation and compact size. One of the best portable generators of this type is the Ryobi Bluetooth Inverter Generator.

While this portable inverter generator offers more limited power compared to larger models, you can power a single major appliance (like your fridge or microwave) or use it to operate several smaller devices simultaneously (phone charger, lamp, fan, etc.). One of the most common gripes with this generator is that filling it with oil is tricky due to the way the unit is designed. However, with a little patience and the right funnel, the job can be done.

Best Battery-Powered: EGO 56-Volt 3,000-Watt Nexus Portable Power Station Generator

EGO 56-Volt 3000-Watt Nexus Portable Power Station

What to Look For in Portable Generators


The wattage of a portable generator indicates how much power it's capable of producing. You should choose a generator with plenty of wattage for the appliances and devices you plan to operate in the event of a power outage or in an off-grid situation.

There are two important metrics to know when evaluating a generator's power: running watts and starting watts. Running watts indicate how much power the generator can continuously produce. Starting watts are also known as surge watts or peak watts, since these are a measure of how much power a generator can produce in short bursts—such as when turning on a major appliance connected to the generator, like a refrigerator.


The type and number of outlets on a portable generator will vary, but typically include a combination of 120V 20 amp household outlets, 120/240V 50 amp receptacles, and 120/240V 30 amp twist-lock receptacles. Some may have GFCI-protected outlets.

Fuel Type

Portable generators rely on fuel to produce power (with the exception of battery-powered options). Gasoline is the most common fuel type for portable generators, though some models offer dual fuel flexibility and can run using gas or propane. Diesel portable generators are also available on the market and offer greater fuel efficiency but these models tend to be more expensive.

An alternative to diesel, gas, or propane portable generators is a battery-powered generator. This is the only type of generator that can be used indoors but it's also popular for camping or off-grid use. Instead of filling it with fuel, a battery portable generator must be charged up using electricity or solar energy.

Operating Noise

Portable generators have a reputation for being noisy. For the sake of your own sanity (and that of your neighbors), check the operational volume (measured in decibels) for any portable generator you consider purchasing. A quiet portable generator may register at about 60 decibels, but many models are between 70 and 80 decibels.

  • How do you hook up a portable generator to a house?

    If you want to connect a portable generator to your home's electrical panel, you will need to hire an electrician to install a manual transfer switch. If you are looking for an easier way to use a portable generator for your household needs, then stick with using a grounded extension cord to bring power into your home from the portable generator located outside.

  • What size portable generator do you need?

    To find the right size portable generator for your situation, start by making a list of which appliances and devices you want to run using generator power. For each item, note the running watts and starting watts from the manufacturer, or use general guidelines found online. Now it's time to do some math. Add up the running watts of all items you want to plug into the generator. Then, look for the item with the largest number of starting watts. Add this starting watts figure to the total running watts you calculated. This is your peak wattage number and should guide you in selecting a generator that produces enough energy for your needs.

  • How do you use a portable generator?

    Set up the generator outside of the home, at a distance of at least 20 feet. It's important to consider safety when using a portable generator, so be sure that the exhaust is positioned in a way that won't enter the home through a door or window. Check that the generator has sufficient fuel. Then, plug the generator into a heavy-duty extension cord. Run the extension cord into the house via a door or window. Plug the appliance that draws the largest electrical current into the extension cord first, then you can add other appliances or devices, being mindful of the generator's power capacity.
