Don't be left in the dark the next time a storm cuts the cord to your home's electricity. With our tips for buying and the best portable generators on the market, you can find the whole-home backup to fit your needs.

The Best Portable Generator for Power Outages

The storm hits. Power lines topple. And your home loses electricity for an hour, a day, or even a week. These inconvenient—and in some cases, downright dangerous—grid failures seem to be more and more prevalent with each passing year. Brief, infrequent outages are a nuisance and if nothing else, remind us of our complete dependence on electricity. But soon enough, the ordeal is over. However, if your area has been experiencing blackouts more frequently, or for more protracted periods, it’s well worth asking this question: If a major storm came rolling into your town tomorrow, would you be ready for the potential consequences?

An electrical outage doesn’t have to mean the suspension of your life until grid power is restored. You can take matters into your own hands, without spending a small fortune, using a portable generator. Deciding you want to buy one is only the first step. Next comes the process of determining which are the best generators to consider for your household. Read on for details on the main considerations to bear in mind as you navigate the assortment of options available and to discover why we’ve chosen these five models as the best portable generators you can get today.

Key Considerations

Portable generators are not “one size fits all”. The best portable generator for you is going to be the one that best 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.

  • Wattage. 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 feel comfortable running during a blackout. Make a list of those must-have appliances, and write down the number of watts that 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 proves sufficient.
  • Fuel Type. That list of must-have appliances also bears on whether the best generators for you to consider are ones that run on batteries, gas, propane, or diesel.
  • Inverter Generators. This category of generators produces electricity in three phases: creating first 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 does this generator 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.
  • Exhaust. Any portable generator that runs on gas, diesel, or propane produces exhaust. For that reason, such machines must be used outdoors, with protection from the weather, at least 15 feet from the house. If you live in California, focus on generators compliant with the standards set by the California Air Resources Board.
  • Noise. Portable gas-powered generators can be pretty loud. But some 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.
  • Accessories. Many things you’d assume are included with a generator must actually be purchased separately, and those incidental costs can add up. 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.
