What to Look for in a Generator

Why Trust The Spruce?

“The end user needs to confirm what they want to be energized during a power outage and add up the watts to the best of their ability,” explained Angelo Cristofolo, manager of residential electrical sales and installations at Air Group, LLC.

We spoke to experts in the electrical industry about the different types of portable generators. We also rounded up some highly rated portable generators across various price points and wattages, and we consulted safety guidance from the U.S.

Department of Energy and the Occupational Safety and Health Administration to outline how to safely use a generator. These days, there are two main types of portable generators: conventional generators and inverter generators, both of which can run on gasoline, propane or diesel fuels.

Propane isn’t as energy efficient as gasoline, but it performs better in colder weather and typically creates less engine maintenance, according to the U.S. Department of Energy.

Neither portable generator should ever be used inside the house, as they can cause fires and produce potentially odorless and deadly carbon monoxide gas, the U.S.

Champion 9375/7500-Watt Electric Start Gas Portable Generator

  • Department of Energy says. Conventional generators are the larger, louder and more powerful type of portable generator.
  • They’re typically strong enough to power larger electronics and appliances like refrigerators and televisions.
  • Inverter generators are smaller and less powerful than conventional generators, but they also provide cleaner energy and their engines power up or down depending on demand.
  • “Most inverter generators are small so they are limited [in] what you can power up, but [they are] convenient, lightweight and efficient for small appliances and devices,” Cristofolo explained.
  • Because inverter generators maintain a more consistent current, they also tend to be more expensive.
  • Both conventional generators and inverter generators require refueling after a certain amount of time — often eight to 10 hours, depending on the load — so even with a few backup cans of gas, they’re ideal for shorter periods of time.
  • That said, both types of generators vary in how much power they can put out.
  • So, as you shop for the best generator for you, tally up how many watts of power you’ll need and buy accordingly.
  • This chart from Lowe’s is a good starting point if you aren’t sure how much wattage you need.
  • Some devices — like refrigerators and window AC units — have both running watts and starting watts to consider.

Best Standby:Champion 12.5-kW Home Standby Generator with 100-Amp Transfer Switch

Cristofolo explained that the starting watts are “that initial burst of power needed to start the [device],” while the running watts are what’s needed to keep the device powered.

The experts we spoke to said that conventional generators can be useful for powering an entire portion of the house, while inverter generators provide the clean energy needed for more sensitive electronics like cell phones.

Since portable generators often weigh hundreds of pounds, all of the options below either come with wheels or have the option to purchase a wheel kit separately. Each option also has a low oil shutdown feature that automatically turns the machine off when it senses that it’s running out of fuel.

Below, we rounded up highly rated options across both types of portable generators, all of which clearly state their maximum running wattage and starting wattage — we top off each recommendation with pertinent takeaways to help your decision.

How to use a portable generator safely

agency released a report recommending a new mandatory standard to equip portable generators with automatic shut-off features when the machines detect carbon monoxide at an unsafe level.

Whether the portable generator you buy has an auto shut-off feature, OSHA offers general safety guidance to help people avoid carbon monoxide poisoning:.

Never use a generator indoors or in an enclosed space like a garage or a basement. Make sure a generator has 3 to 4 feet of clear space on all sides and above it to ensure adequate ventilation.

Do not use a generator anywhere near doors, windows and vents where carbon monoxide might filter in.

Inverter generators

  • Generators can also be an electrocution hazard if you don’t use them properly.
  • OSHA and the U.S.
  • Department of Energy offer the following guidance to help avoid shock and electrocution:.
  • Never attach a generator directly to the electrical system of a structure unless an electrician has installed the generator with a transfer switch.
  • Plug electrical appliances directly into the generator using the manufacturer’s supplied cords or extension cords that are grounded (3-pronged).
  • Never use frayed or damaged extension cords.
  • Only use extension cords that are appropriately rated in watts or amps.
  • Keep your generator dry and under an open structure.
