A portable generator provides power in the event of a power outage, helping you keep essential appliances like the fridge and stove working. It can also help you avoid expensive home repairs, such as a flooded basement or damaged garage door opener, by keeping the sump pump running. And for outdoor events, a generator can make any party or camping trip more fun by powering things like a screen projector, stereo, and a bouncy house.
When shopping for a portable generator, consider the following:
Space: How much space you have to set up and store the unit can impact where and how easily it’s used.
Power needs: A basic rule is to choose a generator that can run up to the total amount of watts needed for your appliances, but be sure to add up the wattage for items like the air conditioner that you want to use. Generators that produce a higher number of watts tend to be heavier and more expensive.
Fuel type: The kind of fuel you use determines how long the generator buy here will last and its maintenance needs. Gasoline is common, but it isn’t the safest choice for generators as it can build up carbon monoxide and increase fire hazards. It also has a shorter shelf life than other types of fuel, and can be difficult to find in the event of a disaster. Fortunately, newer generators are powered by electronic fuel injection that eliminates the need for carburetors, which can be clogged by dirt and other debris.
Other fuel types include liquid propane, natural gas, and diesel fuel. But Consumer Reports generally doesn’t test these models, because they are less common and more complicated to operate than gasoline-powered generators. If you’re interested in a model that runs on one of these other fuels, contact the manufacturer to learn more.
Noise level: It’s no secret that generators can be noisy machines, but the technology to reduce engine noise has improved dramatically in recent years. In fact, some generators are almost silent when they’re operating under load. If noise is a major concern, look for a generator with an inverter motor, which is designed to be very quiet.
Battery-powered inverters are a good option for some portable generators, especially those that are designed to be recharged via solar panels. However, they’re usually more expensive than generators that use gasoline and typically won’t generate as many watts.
A backup generator can keep your refrigerator and freezer running in the event of a power outage, so that you don’t end up with rotten food. It can also keep your sump pump, garage door, and HVAC system functioning so that you don’t come home to a flooded basement or must deal with the unpleasant consequences of mold and mildew in your home. And if you work from home, a portable generator can keep your Wi-Fi, PC, and printer running so that you don’t miss any critical work. Assess your needs, follow proper operating procedures, and maintain your generator as recommended, and it can be a valuable tool during an emergency.
